"Improvement of Pigs Artificial Insemenation Technology"

The effect of various rearing management traits, within one year period, in breeding and fattening gilts to establish sexual maturity, based on the findings of ovarian activity and uterine morphometry post mortem were investigated. Breeding gilts (n=175) were raised in groups of 20 animals in a box with a drop. From 150th days of age, breeding gilts were stimulated daily by direct contact with sexually mature boars. Fattening gilts (n=389) are raised in closed boxes without outlets in groups of 50 animals and were not stimulated by contact with sexually mature boars. In the age of 180 to 190 days, all gilts were sacrificed, and their reproductive organs are reviewed in the laboratory. It has been shown that significantly greater number (61%) breeding gilts achieve pubertal cyclic ovarian activity until the moment of sacrifice in relation to the fattening gilts (26%). Ovulation rate in the first (10.2) and second estrus cycle (12.4) was significantly higher (p <0.01) at breeding, in relation to the fattening gilts (8.5 and 9.7 ovulation). The results clearly show: (1) that the examination of sexual organs post mortem can determine the precise stage of sexual maturation in gilts, and (2) that fattening rearing conditions delay the establishment of puberty in gilts.

"Unapreenje tehnologije vestackog osemenjavanja svinja"

Ispitivan je uticaj nacina odgoja nazimca, tokom jednogodisnjeg perioda, na uspostavljanje polne zrelosti, na osnovu nalaza ovarijalne aktivnosti i morfometrije uterusa post mortem. Priplodne nazimice (n=175) su odgajane u grupama od po 20 grla u boksevima sa ispustima, a od 150. dana starosti su bile stimulisane svakodnevnim direktnim kontaktom sa polno zrelim nerastom. Tovne nazimice su odgajane u zatvorenim boksevima, bez ispusta, u gupama od po 50 grla i nisu bile stimulisane kontaktom sa polno zrelim nerastom. U starosti 180 do 190 dana, sve nazimice su bile zrtvovane, a njihovi polni organi su pregledani u laboratoriji. Pokazalo se da znacajno vei broj (61%) priplodnih nazimica postizu ciklicnu pubertetsku ovarijalnu aktivnost do momenta zrtvovanja u odnosu na tovne nazimica (26%). Ovulaciona vrednost u prvom (10,2) i drugom estrusnom ciklusu (12,4) je statisticki znacajno vea (p<0,01) kod priplodnih, u odnosu na tovne nazimice (8,5 i 9,7 ovulacija). Dobijeni rezultati jasno pokazuju: (1) da je pregledom polnih organa post mortem mogue precizno odrediti stadijum polne zrelosti nazimica, kao i (2) da tovni uslovi odgoja nazimica odlazu uspostavljanje puberteta.

"Establishment and Management of Energy Plantations"

In accordance with the new directive of European Union according to which 20% of energy must be produced from renewable sources (biomass) in EU countries until 2020, it was necessary to convey some studies relating to formation and management of intensive poplar plantations for energy production. The subject of the study was the possibility of using different poplar clones in appropriate habitats, with appropriate technology of stand establishment for the production of large quantities of biomass for its conversion into different forms of energy. During previous stages of the Project investigation aimed at registration of new clones "Bora" and "Antonije". These clones are capable of growing in less favorable soils, with high biomass yield in early growth stage, in the stands with great number of plants per unit area. Also, it is very important that new varieties have high values of volume density, which is very significant in terms of the potential amount of energy resulting from combustion. According to data obtained from PP "Vojvodinasume" in 2009 more than 330.000 m3 of different wood sortiments , from which 256.691 m3 of different trunk classes, as well as 74.296 m3 of spatial (technical) wood were produced. Total mass (weight) of cutting residue, i.e. waste, together with tiny branches was approx. 8.000 t per year. Potential amount of energy that could be obtained by combustion of biomass obtained in this manner was 134.248 GJ annually. Mass of bark obtained by cutting of the mentioned timber quantity was 14,000 t. Potential heat energy that would be obtained by bark combustion, with calorific value higher than the wood is 322.420 GJ. Therefore, the total heat energy that could be produced by combustion of residues obtained after plantations cutting, and collected bark is 456.668 GJ annually. This amount of energy could replace about 3,200 t of oil annually. Total estimated wood volume that could be produced after 10 years on the surface area under management of PP ,,Vojvodinasume" (approx. 1800 ha for this year), and on the potential surface areas that are presently unused (approx. 10,000 ha this year) would exceed 1.800.000 m3. Total estimated amount of residues obtained during cutting on all of the mentioned surface areas together with bark exceeded 200.000m3 ten years after plantation. These are impresive figures, but it should be noted that this is the potential, and that it is necessary to work on finding the opportunities for cost-efficient collection of residues in the forest, at least over smaller distances, and to find opportunities for local use, which would reduce costs of waste collected in this way, and increase efficacy of its local application.

"Osnivanje i gazdovanje zasadima za proizvodnju energije (V faza)"

U skladu sa novim propisima Evropske Unije prema kojima se 20% energije u zemljama EU mora proizvoditi iz obnovljivih izvora energije (biomasa) do 2020. godine, bilo je neophodno obaviti istrazivanja u oblasti osnivanja i gazdovanja intenzivnim zasadima topola za proizvodnju energije. Predmet istrazivanja je bila mogunost korisenja razlicitih sorti topola, na odgovarajuim stanistima, uz odgovarajuu tehnologiju osnivanja zasada za proizvodnju sto vee kolicine biomase za konverziju u druge vidove energije. U toku prethodnih faza Projekta nastavljena su visegodisnja usmerena istrazivanja koja su dovela do registracije novih sorti, ,,Bora" i ,,Antonije". Te sorte su sposobne da rastu na manje pogodnim zemljistima, sa velikim prinosima biomase u ranoj fazi rasta, u zasadima sa velikim brojem biljaka po jedinici povrsine. Takodje, veoma je znacajno da su nove sorte sa visokim vrednostima zapreminske mase koja je veoma znacajna sa aspekta potencijalne kolicine energije nastale sagorevanjem. Prema podacima dobijenim od JP "Vojvodinasume" u 2009. godini proizvedeno je vise od 330.000 m3 razlicitih drvnih sortimenata, od cega 256.691 m3 razlicitih klasa trupaca, kao i 74.296 m3prostornog (tehnickog) drveta. Ukupna masa (tezina) ostataka sece, odnosno otpada, zajedno sa sitnom granjevinom iznosi oko 8.000 tona godisnje. Potencijalna kolicina energije koja bi se mogla dobiti spaljivanjem ovako nastale biomase iznosi oko 134.248 GJ godisnje. Tezina kore koja se dobije secom navedene kolicine drveta iznosi oko 14.000 tona. Potencijalna topolotna energija koja bi nastala sagorevanjem kore, koja ima veu kaloricnu vrednost od drveta,322.420 GJ. Prema tome, ukupna toplotna energija koja bi se mogla proizvesti sagorevanjem ostataka sece i nastale kore iznosi 456.668 GJ godisnje. Ova kolicina energije bi mogla da zameni oko 3.200 tona nafte godisnje. Ukupna procenjena zapremina drvne mase koja bi se proizvela nakon 10 godina na povrsinama kojima gazduje JP "Vojvodinasume" (oko 1800 ha za ovu godinu), kao i na potencijalnim povrsinama koje su trenutno neiskorisene (oko 10.000 ha ove godine), iznosila bi preko 1.800.000 m3 . Ukupna procenjena kolicina otpada priilikom sece na svim navedenim povrsinama, zajedno sa korom, bi premasila 200.000m3 nakon 10 godina gajenja. Ovo su impozantne brojke, ali treba naglasiti da je to potencijal, a da je neophodno da se radi na iznalazenju mogunosti za ekonomicno sakupljanje ostataka u sumi, barem na manjim distancama, i da se pronadju mogunosti lokalnog korisenja, cime bi se smanjila cena tako prikupljenog otpada i poveala ekonomicnost njegove lokalne primene. Opsiran izvestaj u prilogu.

"Improved of Forage Production on the Grasslands of Vojvodina Province and Romania (Territory of Banat)"

In previous project period, 28 locations were selected on permanent grasslands of the Vojvodina Province. Of these locations three tipycal grasslands were selected (Aradac-Banat, Titel-Backa and Krcedin-Srem) in 2009/10. Locations are differ regarding altitude, soil properties and botanical composition i.e. grassland yield and quality. Together with harrowing, the following N treatments (kg ha-1) were applied: control, N40, N80, N120, N160 and Nleg-under sowing with legumes. The investigation included determination of soil properties and botanical composition before treatments and yield and quality after treatments. Regarding soil chemical composition, pH values varied from slightly acid to slightly alkaline. All the locations showed mainly high content of nitrogen and potassium, while phosphorus content varied from high to low. The locations varied regarding floristic composition, i.e., their utility as domestic animal feed. Dry matter yield increased in proportion to N rate. The highest yield were recorded with highest N rate and lowest in the control and Nleg In all three locations, the undersow species did not survive and thus they had not influence forage yield and quality.

''Unapreenje proizvodnje kabaste stocne hrane na travnjacima Vojvodine i Rumunije (na teritoriji Banata)''

U dosadasnjem radu na projektu determinisano je ukupno 28 lokaliteta na teritoriji Banata, Backe i Srema u odnosu na pedoloske osobine, floristicki sastav, prinos i kvalitet krme na travnjacima. U ovoj fazi istrazivanja (2009) odabrana su tri postojea lokaliteta u odnosu na regione (Banat-Aradac, Backa-Titel i Srem-Krcedin), na kojima su zasnovani specificni agrotehnicki ogledi u cilju utvrdjibvanja edekvatne agrotehnike na prirodnim travnjacima Vojvodine. U skladu sa predvidjenom metodikom, praen je botanicki sastav, odnosno kvalitet travnjaka, kvalitet zemljista i sagledavanje uticaja tretmana azota i podsejavanja na prinos i kvalitet travnjaka. Na determinisanim lokalitetima nakon razmeravanja i parcelisanja/odredjivanje tretmana azota, (drljanje + kontrola, N1-40, N2-80, N3-120, N4-160 kg/ha i N5-podsejavanje sa adekvatnom leguminozom u zavisnosti od botanickog sastava travnjaka) utvrdjen je botanicki sastav i kvalitet prirodne fitocenoze/travnjaka, kao i hemijski sastav zemljista. Svi lokaliteti su obelezeni i locirani uz pomo GPS-a. Takodje, primenjene su adekvatne mere za tzv. prezimljavanje travnjaka, u cilju efikasnijeg sprovodjenja i delovanja tretmana (djubrenje) na prolee naredne godine (2010). Analiza zemljista na svim ispitivanim lokacijama ukazuje da je zemljiste u pogledu reakcije zemljisnog rastvora kiselo do neutralno. Povrsinski sloj zemljista od 0-30 cm karakterise se malom kolicinom CaCO3, visokim sadrzajem humusa i azota. Visok sadrzaj humusa moze se objasniti dugogodisnjom akumulacijom biljnih ostataka u povrsinskom sloju zemljista, sto je karakteristicno za prirodne travnjake. Visok sadrzaj pojedinih elemenata moze se tumaciti permanentnim prisustvom stoke (ovaca) na travnjaku, koja gazenjem, ispasom i tzv. torenjem poboljsava kvalitet zemljista. U pogledu botanickog sastava ucese trava se kree od 48 do 66%, leguminoza od 20 do 26% i otzv. Ostalih vrsta od 14 do 20%. Na svim ispitivanim lokalitetima na kontrolnoj varijanti registrovan je prosecan prinos sena za agroekoloske uslove Vojvodine. Kvalitet suve materije zavisi pre svega od botanickog sastava travnjaka, te se razlikuje u zavisnosti od ispitivane lokacije. Upotrebom azota, a posebno fosfora i kalijuma postojei kvalitet travnjaka se moze znacajno poboljsati. Prinos sena raste sa porastom doze azota, tako da je prinos najvei na tretmanu N4, dok je najmanji na kontrolnoj varijanti i varijanti podsejavanja sa leguminozom. Kod podsejavanje prirodnih travnjaka veoma je bitno da se za setvu koriste tzv. endogene vrste koje se inace javljaju u prirodnoj fitocenozi.

"Development of the Integral Protection Measures of Cucumber From Causers of Cucumber Downy Mildew (Pseudoperonospora cubensis) in Order to Obtain a Health-Safe Product for Further Processing and Export"

In accordance to planned program in 2009, research was performed in field and laboratory conditions. A microtrial with three different genotypes which differed in susceptibility to cucumber downy mildew (Pseusoperonospora cubensis) was set up in Zabalj. Each genotype (Haros, Joker and Regal) were treated with fungicides based on active ingredients Fosetyl Al and combination: Cymoxanil+Fosetil Al+Folpet, as well as untreated control. In laboratory, activity of phenols was determined with the aim to correlate with resistance of cucumber to downy mildew, which fulfilled aims of research given for 2009. It is well known that phenols take part in a number of biochemical processes in plants (photosynthesis, pollination-give colour of flowers, protect plant of pathogens and other damages). Two main characteristics of plant phenols are: they amass in large quantities in resistant genotypes and they have ability to limit pathogen growth. Because of that, they are considered to be potential markers of plant resistance to oxidative stress caused by infection. Results gained by phenol analysys in different cucumber genotypes infected with Pseudoperonospora cubensis and protected with fungicides, partly affirmed their protective role in this investigation. At some genotypes and fungicide treatments a growth in the amount of phenols was determined. The highest trend was noted in flavonoids, in all three genotypes, as well as protoanthocyanidin in Regal. These results were in posistive correlation to DPPH values of free radical test, which is expected because DPPH test represents non-enzymatic ability of plants to remove unstable, free radicals. Although expected, synergistic effect did not occur, and therefore, accumulation of all phenols and tannins trailed in samples. This shows that biological activity in cucumber samples did not depend on all phenol classes, but only few like flavonoids and protoanthocyanidin. Considering that a number of compounds take part in antioxidative defence, that were not included in this study (pigments, vitamin E, C, A etc), these results show that oxidative stress represents a very complex metabolic process. Finally, results show that the use of dissolvable phenols as molecular markers, can be usefull in investigation of cucumber resistance to P. cubensis. References:

"Razrada mera integralne zastite krastavca od prouzrokovaca plamenjace (Pseudoperonospora cubensis) u cilju dobijanja zdravstveno bezbednog proizvoda za preradu i izvoz "

U skladu sa predvienim programom plana istrazivanja u 2009. godini, ispitivanja su obavljena u uslovima polja i u laboratoriji. U lokalitetu Zabalj izveden je mikroogled u cetiri ponavljanja sa tri razlicita genotipa krastavca po stepenu otpornosti prema prouzrokovacu plamenjace (Pseudoperonospora cubensis). Svaki genotip (Haros, Joker i Regal) tretiran je sa fungicidom na bazi fosetil-aluminiuma i kombinacije: cimoksanil+fosetil Al+folpet, kao i kontrole -bez tretiranja. U laboratoriji je ispitana aktivnost fenolnih jedinjenja u svakoj varijanti ogleda u cilju utvrivanja korelacije izmeu ovih jedinjenja i otpornosti biljaka prama plamenjaci, cime su ispunjeni ciljevi istrazivanja predvieni u 2009. godini. Poznato je da fenoli ucestvuju u nizu biohemijskih procesa kod biljaka (fotosintezi, oprasivanju -daju boju cvetovima, stite biljke od napada patogena, kao i od drugih osteenja). Dva osnovna svojstva biljnih fenola su da se nakupljaju u znacajnim kolicinama u rezistentnim genotipovima i da imaju sposobnost da ogranice rast patogena. Iz tog razloga mogu se smatrati potencijalnim markerima otpornosti biljaka prema oksidativnom stresu izazvanog napadom patogena. Rezultati dobijeni analizom fenolnih jedinjenja kod razlicitih genotipova krastavca u uslovima zaraze sa P.cubensis i zastite fungicidima, delimicno su potvrdili svoju zastitnu ulogu i u nasim istrazivanjima. Kod pojedinih genotipova i tretmana utvren je porast sadrzaja ovih jedinjenja. Najuocljiviji trend porasta u odnosu na kontrolu je zabelezen kod flavonoida, u sva tri genotipa, a proantocijanidina kod sorte Regal. Dobijeni rezultati su u pozitivnoj korelaciji sa vrednostima DPPH pomou slobodno radikalskog testa, sto je ocekivano s obzirom da DPPH test predstavlja meru neenzimske sposobnosti biljnog ekstrata da uklanja nestabilne, slobodne radikale. Iako ocekivan, sinergisticki efekat i nakupljanje svih klasa fenola je izostalo, te nije doslo do poveanja akumulacije ukupnih fenola i tanina u uzorcima. Ovo pokazuje da nosioci bioloske aktivnosti u uzorcima krastavca nisu sve fenolne klase jedinjenja ve samo pojedine, poput flavonoida i proantocijanidina. S obzirom da u antioksidantnoj odbrani biljaka ucestvuje veliki broj jedinjenja koja u ovoj studiji nisu obuhvaena (razni pigmenti, redukovani glutation, vitamini E, C i A i dr.), iz rezultata proizilazi da oksidativni stres kod biljaka predstavlja veoma slozen metabolicki proces koji ukljucuje velik broj komponenti. Dobijeni rezultati potvruju korisnost upotrebe rasvorljivih fenolnih jedinjenja kao molekularnih markera u proucavanju otpornosti krastavca prema P. cubensis.

"Influence of Probiotics and Prebiotics on Broiler Production and Morphofunctional Characteristics of Broiler's Small Intestines"

The aim of this investigation was to examine the influence of synbiotic and phytogenic additive on morphohistological characteristics of broiler jejunum. In trial were 648 Cobb 500 broiler chickens. Trial were done with tree groups and four replications. First group were control (C), second group (Synb) with addition synbiotic in feed (Biomin® IMBO; 1kg/t in starter feed, 0.5 kg/t in grower feed and 0.25 kg/t in finish feed) and third group (Phyto) with addition of phytogenic blend (Biomin® P.E.P.; 0.125 kg/t in all tree king of feed). Days , 21 and 42 of age, eight broilers per group were sacrified, and jejunum were removed and processing with standard histological procedures. Obtained histological samples were stained with hematoxilin eosine. As histological parameters, villus height, crypt depth, villus/crypt ratio, villus surface, villus width and thickness of the muscular layer were determined. At 21 day of age, differences in all determined parameters were not significant. But, at the end of trial significant differences at 42 day of age were found. Statistical significant difference in villus height and surface were between control and symbiotic groups. In crypt depth significant difference were between control and phytogenic groups. From the results obtained in this experiment can be concluded that the symbiotic and phytogenic additives have a significant impact on the morphohistological parameters of jejunum. References:

"Uticaj probiotika i prebiotika na proizvodne performanse i morfofunkcionalne karakteristike tankih creva brojlera"

Cilj ovog istrazivanja je bio da se ispita uticaj sinbiotika i fitogenih aditva na histomorfoloske karakteristike jejunuma. U ogledu je bilo ukljuceno 684 brojlera hibrida Cobb 500. Formirane su tri grupe sa po cetiri ponavljanja. Prva grupa je bila kontrola (K), druga grupa je u obrok dobijala sinbiotik (Biomin® IMBO) (grupa Sinb), 1 kg/t u starter smesi, 0.5 kg/t u grover i 0,25 kg/t u finiser smesi, a trea grupa fitogeni aditiv (Biomin® P.E.P) (grupa Fit) u koncentraciji 0,125 kg/t i to u sve tri smese. U uzrastima od 21 i 42 dana, po osam zivotinja iz svake grupe (K, Sinb i Fit) su zrtvovane, uzimani su uzorci creva koji su obraivani standardnom histoloskom procedurom. Dobijeni histoloski preparati su bojeni hematoksilin eozinom. Od histomorfoloskih parametara odreivani su visina crevnih resica, dubina kripti, odnos resica i kripti, povrsina crevnih resica, sirina resica, kao i debljina misinog omotaca. Statisticki znacajne razlike izmeu grupa u uzrastu od 21 dan, nisu uocene ni u jednom od posmatranih parametara. Na kraju ogleda, 42. dana, statisticki znacajna razlika u visini crevnih resica i povrsini resica uocena je izmeu kontrolne i grupe koja je dobijala sinbiotik. Statisticki znacajna razlika uocena je i u dubini kripti izmeu kontrolne grupe i grupe koja je dobijala fitogene aditive. Iz rezultata dobijenih u ovog ogledu moze se zakljuciti da i sinbiotik i fitogeni aditivi imaju znacajan uticaj na morfohistoloske parametre jejunuma, a sa tim u vezi, i procese varanja i apsorpcije hranljivih materija.

"Contemporary Approach in Production Practices of Some Medical Plants, with Respect to the Most Important Pest in Vojvodina Province and Romanian Part of Banat"

In production and disposal of medicinal herbs on the choosy European market especially important segment is the way of its protection from diseases and pests. Thus, in 2009 year significant attention was devoted to pathogens monitoring in order to provide recommendations for protection. At two localities (B. Petrovac and R. Sancevi) on experimental plots of the Institute of Field and Vegetable Crops, Novi Sad, conducted a review of herbs and collected samples of plant material with typical symptoms. It was found that on the medicinal herbs in the strongest intensity were present Marigold powdery mildew (Podosphaera xanthii) and Wormwood rust (Puccinia absinthii). Also it was found occurrence of Alternaria alternata on the Marsh mallow, Fusarium sp. on Pot marigold and were noticed the causes of spotting and drying, whose etiology should be further investigated. In experiment with sowing density at 4 Marigold varieties, conducted on the methodology from the previous year, were taken samples of plant material for analysis of chemical composition of drugs by different harvesting times. Chemical quality analyses are in progress. Along with the testing in field conditions, in semi-controlled conditions carried out the fertilization experiment in Mitscherlich's pots. The greatest number of flowers in the experiment formed by a local variety Backi Petrovac, most flowers was formed at the highest N doses, while the largest flowers obtained at the middle N-doses. The total yield of fresh and dry flowers was the highest at the variety Plamen Plus. Drug yield was equal on the variants with 1.5 and 1g N/pot, and significantly higher compared to the control and the dose of 0.5 g N/pot. In the 2009th year in the experiments included a new species - the basil. The crop was established by direct sowing in early July 2009, and for sowing is used variety Sitnolisni. Crop was irrigated in 4 times with 35 l/m2 water. During the growing season were measured most important ago-biological features and studied the dynamics of yield formation. Also, the experiment with the height of mowing was performed in the initial stage of flowering (at 5, 10, 15, 20 and 25 cm from the ground). At all variants was expressed good plants regeneration. Results showed that with proper agro-measures and irrigation it is possible to achieve a high yield of herb and essential oil content in the later time of basil sowing. References:

"Savremeni pristup tehnologiji gajenja nekih lekovitih biljaka sa osvrtom na najznacajnije patogene u Vojvodini i rumunskom delu Banata"

U proizvodnji i plasmanu lekovitog bilja na probirljivo evropsko trziste narocito vazan segment je nacin njegove zastite od bolesti i stetocina. Stoga je u 2009. godini znacajnija paznja posveena praenju patogena, a u cilju davanja preporuka i mera zastite koje nee narusavati postojei kvalitet. Na dva lokaliteta (B. Petrovac i R. Sancevi) na oglednim parcelama Instituta za ratarstvo i povrtarstvo u Novom Sadu, obavljen je pregled lekovitog bilja i sakupljeni uzorci biljnog materijala sa karakteristicnim simptomima. Utvreno je da je na lekovitom bilju u najjacem intenzitetu prisutna pepelnica nevena (Podosphaera xanthii) i ra pelena (Puccinia absinthii). Konstatovana je i pojava Alternaria alternata na belom slezu, Fusarium sp. na nevenu i odreeni prouzrokovaci pegavosti i susenja, ciju etiologiju dodatno treba ispitati. U ogledu sa gustinama setve kod 4 sorte nevena, postavljenom po metodici iz prethodne godine, uzeti su i uzorci biljnog materijala za analizu promene hemijskog sastava droge po razlicitim vremenima berbe. Hemijske analize kvaliteta su u toku. Uporedo sa ispitivanjem u poljskim uslovima, kod istih sorti izveden je i ogled sa ubrenjem u Mitscherlich-ovim sudovima, u polukontrolisanim uslovima u vegetacionoj kui. Ispitivan je uticaj rastuih kolicina azota na prinos svezih i suvih cvasti te njihov broj i krupnou. Najvei broj cvasti u ogledu formirala je domaa sorta Backi Petrovac, najvise cvasti formirano je pri najveim dozama N, dok su najkrupnije cvasti dobijene pri srednjim dozama. Ukupan prinos svezih i suvih cvasti bio je najvei kod sorte Plamen Plus. Prinos droge bio je podjednak na varijantama sa 1,5 i 1 g N/sudu, a znacajno vei u odnosu na kontrolu i dozu od 0,5 g N/sudu. U 2009. godini u oglede je ukljucena i nova vrsta ­ bosiljak. Usev je zasnovan direktnom setvom pocetkom jula 2009. godine, a za setvu je korisena sorta Sitnolisni. Usev je navodnjavan u 4 navrata sa po 35 l/m2 vode. Tokom vegetacije merene su najvaznije agobioloske osobine i praena dinamika formiranja prinosa. Takoe, izveden je i ogled sa visinom kosidbe herbe u pocetnoj fazi cvetanja (na 5, 10, 15, 20 i 25 cm od zemlje). U svim varijantama kosidbe bila je izrazena dobra regeneracija biljaka. Rezultati su pokazali da je uz odgovarajue mere nege i navodnjavanje mogue postii visok prinos herbe i sadrzaj etarskog ulja i u kasnijem roku setve bosiljka.

"Ecological and Energetic Aspects of Various Land Cultivation Technologies"

In autumn 2008 and 2009 an experiment was set up for harvest of wheat, maize, and sugar beat in Srem and Banat. Experiments were set up using three systems of soil tillage and sowing of cultivars: conventional tillage (used for experiment control), conservation tillage, and strip tillage. In comparison with conventional tillage, substantial energy savings were achieved in wheat production using conservation tillage: fuel consumption savings 11 l/ha, machine labour savings 0,6 h/ha, energy consumption savings 85 kWh/ha. In sowing of maize and sugar beat, largest energy savings were achieved by strip tillage. Relative ratios of energy parameters between conventional, conservation, and strip tillage in tillage and sowing of sugar beat and maize are given below: 1. 2. 3. Fuel consumption 1:0,75:0,5 for maize, 1:0,72:0,4 for sugar beat, Productivity 1:2:3 for maize, for 1:2:4 sugar beat, and Engaged energy 1:0,81:0,45 for maize, for 1:0,88:0,25 sugar beat.

The testing of spring-tine harrow in sowing of maize, soybean, and sugar beat has been continued. For the previously defined crop growth stages, the application of spring-tine harrow resulted in excellent mechanical weed control (approx. 85%) with minimum crop damage and spacing from 0,6 to 1,5 %.

"Ekoloski i energetski aspekti razlicitih tehnologija obrade zemljista"

U jeseni 2008. i 2009. god. postavljen je ogled u setvi psenice, kukuruza i seerne repe, u Sremu i Banatu. Ogledi su postavljeni uz primenu 3 sistema obrade i setve ratarskih kultura. Primenjena je konvencionalna obrada kao kontrola, konzervacijska obrada i minimalna konzervacijska (strip till) obrada. U proizvodnji psenice realizovane su znacajne energetske ustede primenom konzervacijske u odnosu na konvencionalnu obradu i setvu i to: usteda goriva u proseku 11 l/ha, masinskog rada 0,6 h/ha, angazovane energije 85 kWh/ha. Pri setvi kukuruza i seerne repe najvee energetske ustede su ostvarene primenom delimicne konzervacijske obrade (strip till). Relativni odnosi analiziranih energetskih pokazatelja kod obrade i setve seerne repe i kukuruza konvencionalne prema konzervacijskoj i prema strip till obradi: 1. potrosnje goriva 1:0,75:0,5 za kukuruz, odnosno 1:0,72:0,4 za seernu repu, 2. produktivnost 1:2:3 za kukuruz, odnosno 1:2:4 za sernu repu i 3. angazovana energija 1:0,81:0,45 za kukuruz, odnosno 1:0,88:0,25 za seernu repu. Nastavljeno je ispitivanje Eko drljace u usevu kukuruza, soje i seerne repe. Uz ranije definisane faze uzrasta useva za primenu Eko drljace ostvareni su izvanredni efekti mehanickog unistavanja korova oko 85% uz neznatna ostecenja useva i proreivanja od 0,6 do 1,5 %.

"Research on Typisation of Aviary and Other Kinds of Virus Influence by Molecular Diagnostic Techniques"

In this research period the attention was directed to the determination of the systemic and local humoral immune response in the animals included in vaccination against bovine herpsevirus-1 (BHV1). Systemic humoral response was monitored through the detection of specific antibodies against BHV-1 in cow blood sera at the moment of calving, and in the blood sera from their calves immediately after calving, but before intake of colostrum. The study included 106 cow and 107 calves (one twin calving). The cows and their offspring derived from 5 herds where the infection with bovine herpesvirus-1 had been detected earlier. The virus neutralization test was used for detection of antibodies against BHV-1. Neutralizing anti-BHV-1 antibodies were detected in all cow blood sera and in blood sera taken from 16 calves before colostrum ingestion. The antibody titre in cows sera ranged from 1:4 to 1:512, and in calves sera from 1:2 to 1:16. It is well known that the bovine herpesvirus-1 (BHV-1) entry site is the nasal and conjunctive mucosa. For that reason determination of the concentration of anti-BHV-1 IgM and IgG antibodies, as effectors of humoral immune response, was performed from nasal cavity secretes (mucus). ELISA method was used for the determination of immunoglobuline immediately before vaccination and on several occasions after vaccination with attenuated anti-BHV-1 vaccine. The discharge was sampled using a sponge swab, placed deeply into the nasal cavity for 10 minutes. The experiment was conducted with two groups (10 experimental and 10 control animals). During the whole examination the values of IgM concentrations were different - unequal, with a tendency of decline in both groups. On the day of vaccination the average value of IgM was 2266 ng/mL, at day 5 after the vaccination was 1985 ng/mL, at day 14 (the day of revaccination) 2130 ng/mL, and at day 19 (which is 5 days after revaccination) was 1968 ng/mL. However, the detected concentration of IgA antibodies in the examined animals were more equal, and by looking at the average value it can be concluded that during the examination the concentration of IgA was in a mild increase. An average concentration of IgA class was 2320 ng/mL at the day of vaccination, 2480 ng/mL at day 7 after the vaccination, 2436 ng/mL at day 14 (the day of revaccination) and 2501 ng/mL at day 21 (7 days after revaccination). After the analyses of the specific antibody titers against BHV-1 detected in blood sera from calves before colostrums ingestion, certain conclusions may be made. The detected antibodies in calves point that the infection of fetus with BHV-1 does not have to end up with stillbirths or abortions. However, this points to a need for examination in the situations like selection of the future breeding animals or when a vaccination program for calves is to be designed. The detected concentration of IgM and IgG antibodies in nasal secrete is the significant evidence of local immune reactivity, but their function needs to be evaluated through the determination of the specific antibody titers against BHV-1.

"Izucavanje implementacije programa kontrole i eradikacije herpesvirusne infekcije u priplodnim zapatima goveda"

U ovom istrazivackom ciklusu ispitivanja su bila usmerena na utvrivanje sistemskog i lokalnog humoralnog imunog odgovora kod zivotinja predvienih za vakcinaciju protiv goveeg herpesvirusa-1 (BHV-1). Sistemski humoralni imuni odgovor praen je utvrivanjem specificnih antitela protiv BHV1 u krvnom serumu krava u momentu poroaja i njihove teladi odmah posle roenja, a pre uzimanja kolostruma. Ispitivanjima je bilo obuhvaeno 106 krava i 107 njihove teladi (jedna krava je otelila blizance). Ispitivane krave i njihova telad poticali su iz 5 zapata u kojima je ranijim ispitivanjima utvrena infekcija goveim herpesvirusom-1. Utvrivanje antitela protiv BHV-1 vrseno je metodom virus neutralizacije i utvrena su u svim uzorcima krvnih seruma krava i u 16 uzoraka prekolostralnih krvnih seruma teladi. Vrednosti titra antitela su iznosile kod krava od 1:4 do 1:512, a kod teladi od 1:2 do 1:16. Poznato je da su vrata infekcije goveeg herpesvirusa-1 sluzokoze nosne duplje i ociju. Iz tog razloga je vrseno utvrivanje koncentracije IgM i IgG klase u sekretu (sluzi) nosne duplje, koji predstavljaju efektore humoralnog imunog odgovora u funkciji antitela. Utvrivanje koncentracije imunoglobulina, vrseno je imunoenzimskim testom (ELISA) neposredno pred vakcinaciju i u vise navrata posle sprovedene vakcinacije atenuiranom anti BHV-1 vakcinom. Sekret je uziman pomou tampona od sunera, koji je bio postavljen duboko u nosnoj duplji i drzan oko 10 minuta. U eksperimentu je bilo ukljuceno 20 junadi, od cega je 10 cinilo eksperimentalnu, a 10 junadi kontrolnu grupu. Utvrene koncentracije IgM klase, tokom citavog perioda ispitivanja, bile su neujednacene i imale su tedenciju opadanja, kako u oglednoj, tako i u kontrolnoj grupi. Na dan vakcinacije prosecna vrednost IgM klase iznosila je 2266 ng/mL, 5. dana 1985 ng/mL, 14. dana (dan revakcinacije) 2130 ng/mL, a 19. dana, odnosno 5 dana po revakcinaciji 1968 ng/mL. Meutim, utvrene koncentracije IgA klase kod iste junadi bile su ujednacenije, a analizirajui prosecne vrednost moze se rei da je koncentracija IgA klase tokom perioda ispitivanja bila u blagom porastu. Prosecna koncentracija IgA klase na dan vakcinacije je iznosila 2320 ng/mL, 7. dan 2480 ng/mL, 14. dan (dan revakcinacije) 2436 ng/mL i 21. dan (7. dan po revakcinaciji) 2501 ng/mL. Analizom utvrenih vrednosti titra specificnih antitela protiv BHV-1 kod teladi, pre ishrane kolostrumom mogu se izvesti znacajni zakljcci. Utvrena antitela kod teladi ukazuju da se infekcija fetusa BHV-1 ne mora uvek da zavrsi uginuem i pobacajem. Meutim, ovakav nalaz upuuje na potrebu ispitivanja u situacijama kada se vrsi odabir buduih priplodnjaka ili kada se izrauje program imunoprofilakse teladi. Utvrene koncentracije IgM i IgG klase u sekretu nosne duplje su znacajan pokazatelj lokalne imunosne reaktivnosti, ali njihova funkcija zahteva da se potvrdi utvrivanjem vrednosti titra specificnih antitela protiv BHV-1.

"Comparative Analysis of Animal Health in Zoo and Wild Animals and Risk of Transmission to Humans"

This study showed importance of gastrointestinal and lung parasites to sheep menagement practice and effect of antihelmintic drug - doramectin. After one dose treatment with this antiparasitic drug, we registered 100 % reduction for Trichostrongylus spp, Dyctiocaulus spp and Strongyloides spp., 91,9% for Nematodirus spp and resistence only for Trichuris spp. 28 days after treatment. Becouse of high efficiacy of doramectin it will be drug of choice in our region. Our preliminary results with nematofagous yeast Duddingtonia flagrans must be continue with different doses and shedules of peroral administration, becouse we didn't registered reduction of parasites in sheep. Infection with tissue protozoa Neospora caninum, which is causal agent of abortion in sheep and calf, we registered in 6,81% sheep, and in dogs, as natural reservoir, prevalence was 9,7%. We registered high prevalence (29,5% ) of Toxoplasma gondii antibodies in sheep in our region. Coprological examination of zoo animals from Palic, was made in three times, and one dose of antihelmintic treatment is 100% efficient in carnivores. References:

"Komparativna analiza zdravstvenog stanja zivotinja u ZOO vrtovima i divljoj prirodi i potencijalni rizik za sirenje parazitskih bolesti na ljude"

U cilju ispitivanja pojave rezistencije na novije antiparazitske lekove, ispitali smo uticaj doramektina na zeludacno-crevne i plune nematode ovaca. Rezultati ukazuju na visoku zarazenost (93,3%) ovaca. Nakon jednokratnne primene doramektina, cetvrtog dana doslo je do potpune eliminacije Trychostrongylus spp., Strongyloides spp i Dyctiocaulus spp. dok je za Nematodirus redukcija parazita iznosila 91,9%. Na Trichuris spp. registrovana rezistencija i 28 dana nakon primene doramektina. Zbog visoke efikasnosti doramektin se moze smatrati lekom izbora u lecenju parazitskih nematoda na nasem podrucju i rezistencija za sada nema veliki zncaj. Noviji podaci govore o uticaju nematofagne gljive Dudingtonia flagrans, na helminte kod prezivara, ali u nasem preliminarnom istrazivanju nije dokazana redukcija parazita kod 30 ovaca nakon peroralne primene ciste kulture ove gljive u dozi od 1 milion spora /ml. Infekcija sa Neospora caninum, protozoom koja uzrokuje pobacaje kod goveda i ovaca, registrovana je kod 6,81% ovca, a kod pasa kao prirodnih rezervoara, na uzorku od 31 zivotinje povisen titar antitela registrovan je kod 9,7%. Povisen titar antitela na Toxoplasma gondii naen je kod 29,5% ovaca. Koproloski pregled zivotinja u ZOO vrtu Pali, uraen je u tri navrata, a jednokratna dehelmintizacija stoprocentno je eliminisala crevne parazite kod mesojeda.

"Monitoring of Deoxynivalenol in Cereals and Feeds in Vojvodina"

The aim of this study was deoxynivalenol (DON), mycotoxin, the most frequently detected one throughout the world of the trichothecene family. Consumption of contaminated feeds by livestock has been associated with a variety of adverse health effects including feed refusal, emesis and reduced weight gain. During 2009. we have collected from area of Vojvodina, 108 samples of cereals and feed. Deoxynivalenol was determinated by Enzyme Immunoassay (ELISA). A significant attention was paid on maize and wheat maize because these cereals are especially sensitive to Fusarium graminearum fungus which often produces DON. In maize samples (65) the presence of DON was 23.1%. 34 samples of wheat were analyzed and presence of DON in wheat 8.8% was established. In 4 analyzed soybean and soybean meal samples was not established presence of DON. In 5 analyzed sunflower and sunflower meal samples was established presence of DON 20.0%. Analyzed wheat is precisely the sorts that are most common in the territory of Vojvodina, and these samples are provided in cooperation with the Institute of Field and Vegetable Crops. However, in analyzed samples, the level of DON was not above the maximum level adopted by the EC. The primary aim was achieved, which means that data about presence and DON content on area of Vojvodina are supplemented. Our study is going to be continued, because we believe that every following year, meaning harvest, conduces reliable representation of DON presence in our crops. References:

"Monitoring deoksinivalenola u zitaricama i hranivima Vojvodine"

Kao i prethodnih godina, predmet nasih istrazivanja je bio deoksinivalenol, mikotoksin, cije prisustvo u hrani za zivotinje izaziva odbijanje hrane, povraanje i konacno gubitak njihove tezine. Posledica infekcije plesnima koje produkuju deoksinivalenol, dovodi do smanjenja velicine zrna, kolicine proteina i stetnog uticaja na klijavost, sto rezultira smanjenju prinosa i kvaliteta hraniva. Potreba za ovakvim ispitivanjem se nametnula iz razloga, sto za nasu zemlju nisu postojali pouzdaniji podaci o sadrzaju ovog mikotoksina u zitaricama. Nakon istrazivanja tokom 2004.-2008., nastavilo se sa prikupljanjem uzoraka sa podrucja citave Vojvodine. Ukupan broj prikupljenih uzoraka tokom 2009. godine je iznosio 108. Analiza deoksinivalenola je raena primenom imunohemijske (ELISA) metode. Sakupljen je i analiziran najvei broj uzoraka kukuruza (65), jer je ova kultura uz psenicu najvise osetljiva na prisustvo Fusarium graminearum, plesni koja najcese produkuje DON. Uzorci kukuruza su sakupljeni neposredno nakon zetve i analizirani sa prirodnim sadrzajem vlage. U analiziranim uzorcima kukuruza utvrena je prisutnost DON-a od 23,1%. Analizirano je 34 uzorka psenice i utvrena je prisutnost DON-a od 8,8%. U svega 4 analizirana uzorka soje i sojinog griza nije utvrena prisutnost DON-a, dok je u 5 analiziranih uzoraka suncokreta i suncokretove sacme utvreno da je 1 uzorak bio pozitivan (20,0%). Maksimalno dozvoljene koncentracije preporucene od strane Evropske komisije nisu prekoracene ni u jednom uzorku. Analizirana psenica predstavlja upravo one sorte koje su najzastupljenije na podrucju Vojvodine (Dragana, Pobeda, Renesansa, Ljiljana, Simonida, Takovcanka, Evropa i druge), a ovi uzorci su obezbeeni u saradnji sa Institutom za ratarstvo i povrtarstvo. Planirani cilj ovog istrazivackog projekta je realizovan, sto znaci da su dopunjeni podaci o prisutnosti i sadrzaju deoksinivalenola na podrucju Vojvodine. Nasa istrazivanja nastavljamo, jer smatramo da je svaka sledea godina, odnosno zetva doprinosi verodostojnijoj slici prisutnosti DON-a u nasim usevima.

"Soybean Grain with Reduced Content of Tripsin Inhibitor in Pig Fattening Feeds"

In order to decrease the cost of processing soybean grains and reducing the cost of pig production examined the possibility of usage raw soybean (RSB) grain without previous processing, with emphasis on varieties with low level tripsyn inhibitor. Study are included in the fattening pigs that were fed a mixture that is'nt processed soybean with low level tripsin inhibitors included in the amount of 0%, 5%, 10% and 15%. The average daily gain in fattening pigs in the group without the participation of soybean with low level inhibitors tripsin was 811 g. In the group where the participation of grain amounted to 5% has an average daily gain of 805 g. Increase participation soybean with low level tripsin inhibitors led to decrease in daily growth and, at the level of 10% was 737 g, while the level of 15% was 706 g. Consummation food was equalized and ranged from 2.10 to 2.13 kg. Conversion kg of food for growth in the group without the participation of soybean with low level tripsin inhibitors was 2.61 kg. Including soybean grains with low level tripsin inhibitors increased conversions. At the lowest level of grain than 5% of conversion was 2.64 kg, increasing to 10% resulted in the conversion of 2.88 kg, and the worst conversion is achieved at the level of 15% and was 2.97 kg. The results indicate that it non processed soybean with low levels tripsin inhibitors may be somewhat used in the diet of pigs in the fattening.

"Sojino zrno sa smanjenim sadrzajem tripsin inhibitora u ishrani svinja u tovu"

U cilju smanjenja troskova obrade sojinog zrna i pojeftinjenja proizvodnje svinjau tovu ispitivana je mogunost njenog korisenja kao sirovog zrna bez predhodne obrade, sa akcentom na sortu sa nizim nivoom tripsin inhibitora. Ispitivanjem su obuhvaene svinje u tovu koje su hranjene smesama u koje je ne obraeno sojino zrno sa nizim nivoom tripsin inhibitora ukljuceno u iznosu od 0%, 5%, 10% i 15%. Prosecan dnevni prirast svinja u tovu u grupi bez ucesa sojinog zrna sa nizim nivoom tripsin inhibitora iznosio je 811 g. U grupi gde je ucese ovog zrna iznosilo 5% ostvaren je prosecan dnevni prirast od 805 g. Poveanje ucesa sojinog zrna sa nizim nivoom tripsin inhibitora dovelo je do smanjenja dnevnog prirasta i to, pri nivou od 10% iznosio je 737 g, dok je pri nivou od 15% iznosio 706 g. Konzumacija hrane je bila ujednacena i kretala se od 2,10 do 2,13 kg. Konverzija hrane za kg prirasta u grupi bez ucesa sojinog zrna sa nizim nivoom tripsin inhibitora iznosila je 2,61 kg. Ukljucenjem sojinog zrna sa nizim nivoom tripsin inhibitora poveavala se konverzija. Pri najnizem nivou ovog zrna od 5% konverzija je iznosila 2,64 kg, poveanjem na 10% rezultiralo je konverzijom od 2,88 kg, a najlosija konverzija je ostvarena pri nivou od 15% i iznosila je 2,97 kg. Dobijeni rezultati ukazuju da se ne obraeno zrno soje sa nizim nivoom tripsin inhibitora moze donekle koristiti u ishrani svinja u tovu.

''Cornelian Cherry (Cornus Mas L.) Selection for Organic Fruit Production in the Vojvodina Province''

During the last period of the research is located and marked with GPS positioning system for 26 new Cornelian cherry genotypes. Previously isolated genotypes, as well as new located have been involved in all phases of testing in 2009. year. In all genotypes accompanied by phenophases flowering, leaves and ripening. The fruits of the trees were marked in the defense phase of full maturity and on 50 fruits per genotype were performed morphometric measurements (length and width of fruits, fruit weight and stone), based on which index is calculated form of fruits and flesh to stone ratio, as an important indicator of the economic feasibility of growing particular Cornelian cherry genotype. After separation from the stone, located mezokarp new genotype of 2009 is analyzed in detail the content of total dry matter content of soluble substances, acids, total and reducing sugars, sucrose content, vitamin C, protein, tannin, cellulose and Ca pectates. Also, the mineral composition was determined (Cu, Fe, Zn, Mn, Mg, K, Na, Ca). Separate seeds from all fruits were treated different preparations in order to accelerate the germination and placed in the stratification. In October 2009, sown in the experimental nursery Rimski Sancevi seeds that were stratified in the preceding research period, and is expected to germinate during the vegetation period of 2010. Since the production process of generative rootstocks very time consuming and uncertain, grace March 2010 imported in 2000 year Cornus mas L. seedlings that will be ready for grafting in August 2010, with the aim of accelerating the production of finished Cornelian cherry trees, for which the government very great interest, as here and in neighboring countries. During the summer months of 2009 the first successful experimental rooted green cuttings that are planted in September, and their acceptance and growth will be monitored during the vegetation period 2010th year. In February this year, Cornelian cherry hardwood cuttings are taken from parent trees and treated with various regulators and put on rooting, and the result is expected during the 2010th year.

"Selekcija drena (Cornus mas L.) u Vovjodini za organsku proizvodnju voa"

Tokom proteklog istrazivackog perioda locirano je i obelezeno GPS sistemom za pozicioniranje 26 novih genotipova drena. Prethodno izdvojeni genotipovi, kao i novo locirani su bili ukljuceni u sve faze ispitivanja tokom 2009. godine. Na svim genotipovima praene su fenofaze cvetanja, listanja i zrenja. Plodovi sa obelezenih stabala su obrani u fazi pune zrelosti i na 50 plodova po genotipu izvrsena su morfometrijska merenja (duzina i sirina ploda, masa ploda i kostice), na osnovu cega je izracunat index oblika ploda i randman, kao veoma bitan pokazatelj ekonomske opravdanosti gajenja odreenog genotipa drena. Nakon odvajanja od kostice, mezokarp novo lociranih genotipova iz 2009 godine detaljno je analiziran na sadrzaj ukupne suve materije, sadrzaj rastvorljive materije, kiseline, ukupne i redukujue seere, sadrzaj saharoze, vitamina C, proteina, tanina, celuloze i Ca pektata. Takoe, utvren je mineralni sastav (Cu, Fe, Zn, Mn, Mg, K, Na, Ca) mezokarpa ploda navedenih genotipova drena. Izdvojeno seme iz svih plodova je tretirano razlicitim preparatima u cilju ubrzavanja procesa klijanja i stavljeno na stratifikaciju. U oktobru 2009 godine posejano je u semeniste rasadnika Oglednog polja na Rimskim Sancevima seme koje je bilo stratifikovano u prethodnom istrazivackom periodu, i ocekuje se klijanje tokom vegetacionog perioda 2010 godine. Obzirom da je proces proizvodnje generativnih podloga drena veoma dugotrajan i neizvestan, pocekom marta 2010 godine uvezeno je 2000 sejanaca drena koji e biti spremni za kalemljenje u avgustu 2010, a sve u cilju ubrzavanja proizvodnje gotove sadnice drena, za kojom vlada izuzetno veliko interesovanje, kako kod nas, tako i u okolnim zemljama. Tokom letnjih meseci 2009 godine uspesno su prvi put ogledno oziljene zelene reznice drena, koje su posaene u septembru u rastilo, a njihov prijem i porast e se pratiti tokom vegetacionog perioda 2010. god. U februaru ove godine, zrele reznice drena su skinute sa maticnih stabala i tretirane razlicitim regulatorima te stavljene na oziljavanje, a rezultat se ocekuje tokom 2010. god.

"The Role of Stationary Long-Term Experiments in Achievement of Environmental Protection and Optimal Yields of the Most Important Field Crops in Vojvodina Province"

The use of mineral fertilizers, which is based on a scientific basis, has a growing importance in the modern cropping technology. This project comprises of four long-term experiment. Investigations concerning the effect of organic and mineral fertilizers on the yield of four crops: sugar beet, maize, spring barley and wheat. Since organic fertilizers manure, liquid manure and crop residue in combination with five doses of N 0-200 kg / ha and 20 combined with NPK fertilizer in quantities of 0,50,100 and 150 kg in all the different rearing systems. The use of organic fertilizers has affected positively on the yield of all four crops. The highest average yields were obtained in treatments where the applied 100 kg/ha N. Yield of sugar beet has increased the amount to 100 kg N/ha, while the technological quality of roots and sugar yield decreased at higher amounts of N from 50 kg/ha. Yields of wheat ranged from 772 kg ha/ha (control) to 7857 kg/ha in variant three crop rotation with 100 kg N/ha. Were taken and soil samples for agrochemical analysis, and particularly the content of organic C in the soil. The fertilized variants was confirmed by the reduction of humus in soil which has a 10% lower values than the values that are determined at the time of establishing the experiment. They also analyzed the physical properties of soil (density, structure and texture). Start the exploration results show that the application of microbial fertilizers positively influence the development of microorganisms in the soil, but differently depending on the dose of N applied and whether the crop residue plowed or not.

"Visegodisnji stacionirani ogledi u funkciji ocuvanja zivotne sredine i postizanja optimalnih prinosa najvaznijih ratarskih biljaka u Vojvodini"

Upotreba mineralnih ubriva, koja se zasniva na naucnoj osnovi, ima sve vei znacaj u savremenom pristupu tehnologiji gajenja rataskih biljaka. U ovaj projekat ukljucena su cetiri visegodisnja ogleda. Ispitivanja se odnose na uticaj organskih i mineralnih ubriva na prinos cetiri ratarske kulture: seerna repa, kukuruz, jari jecam i psenica. Od organskih ubriva ispituju se: stajnjak, tecni stajnjak i zetveni ostaci u kombinaciji sa pet doza azota od 0-200 kg/ha i 20 kombinacija ubrenja sa NPK hranivima u kolicinama od 0,50,100 i 150 kg sve u razlicitim sistemima gajenja. Primena organskih ubriva uticala je pozitivno na prinos sve cetiri gajene biljne vrste. Najvei prosecni prinosi kukuruza ostvareni su na varijantama gde je primenjeno 100 kg/ha N. Prinos korena seerne repe se poveavao do kolicine 100 kg N/ha, dok se tehnoloski kvalitet korena i prinos seera smanjivao pri kolicinama N veim od 50 kg/ha. Prinosi psenice su se kretali od 772 kg/ha (kontrola) do 7857 kg/ha na varijanti tropolja sa 100 kg N/ha. Uzimani su i uzorci zemljista radi agrohemijskih analiza, a posebno sadrzaja organskog C u zemljistu. Na ubrenim varijantama je potvreno smanjenje sadrzaja humusa u zemljistu koja ima za 10% manju vrednost u odnosu na vrednosti koje su utvrene u vreme zasnivanja ogleda. Takoe su analizirana i fizicka svojstva zemljista (zapreminska masa, struktura i mehanicki sastav). Rezultati israzivanja pokazuju da primena mikrobioloskih ubriva pozitivno utice na razvoj mikroorganizama u zemljistu, ali razlicito u zavisnosti od doze primenjenog N i toga da li su zetveni ostaci zaorani ili ne.

"Clonal Selection of Domestic (Autochthonic) Grapevines Cultivars in Vojvodina"

Vineyards housing traditional old cultivars are very few in existence and are quite spread out in the country side. Furthermore properly maintained vineyards where actual scientific research can take place are even more sparse, thus making this research even more challenging. In 2009 the researchers visited and identified 10 additional vineyards on top of the 19 vineyards identified in 2008 that indepth research could be performed. The Vineyard geographic research and visitation encompassed the whole of Vojvodina including Bac, Stara Moravica, Curug, Sivac, Ridica, Stanisic and Biserno Ostrvo. The first criteria was to identify the best maintained vineyards for research. It was determined that the most authentic vineyards were nested on sandy and normaly soil, planted and replanted with vinifera rootings, where they have survived for better part of plus 100 years. Following the trail of the old cultivars in Vojvodina poses a significant challenge as there are various nomenclatures given to the same cultivar across the different local regions makes the detective work even more challenging. Some of the cultivars will be identified and documented during the 2010 growing season based on pictures and the international cultivar atlases which researches are expecting to receive the updated versions from their respective colleagues abroad. During the second course of the 2009 vineyard visits, the researchers picked grapes from the previous year marked vines in vineyards and brought the samples over for further research at the Sremski Karlovce research station. Unfortunately, on some of the vines there was such little yield due to age of the vine or in-climate weather or birds that they could not yield any tangible samples. Part of the identified samples were left with the vineyard owners to make wine in order to close the loop on the research. On these identified and processed that is mentioned above, researchers do not have any sugar and acid contents readings, due to the fact that the respective vineyard owners did not have appropriate equipment for that measurements. From 107 identified vines, researches yielded 81 samples which were brought over to the research station at Sremske Karlovce. From the 81 samples collected they generated 66 wines as the quantities were so small that some of the batches just did not materialize. They made wines from the following cultivars: Moravka (Frankovka), Portugizac, Prokupac, Crna Slamenka, Bela Slamenka, Crvena Slamenka, Kreaca (Banatski rizling) and Seudsa. They produced 6 wines from Stejanovaci and Ridica where the identification of the cultivar is just under way. The commission which was formed to test the wines, recognized as a commission for the award "Najbolje iz Vojvodine" founded by the EC of the APV, was satisfactory based on the limited quantity produced, however the grading on the balance of cultivar follows here forth: The best scored wines 1/1 sample of Prokupac from Rivice with 18.4 points, followed by 1/3 sample of potugizac from Sremski Karlovaca with 18.1 points, 18/1 samples kreaca from Vrsac with 18 points, 22/1 sample of bele slamenke from Berkasova with 17.8 points, etc. The commission conclusion on this project was that this work is critically important and merits continuing.

"Klonska selekcija izvornih (autohtonih) sorti vinove loze"

Vinograda sa starim sortama ima malo, rastrkani su, i cesto za istrazivace nedostupni. U 2009. godini su istrazivaci pored 19 odabranih vinograda iz 2008. obisli jos 10-ak u razlicitim delovima Vojvodine (Bac, Stara Moravica, Curug, Sivac, Riica, Rivica, Stanisi, Biserno Ostrvo). Prvobitni stav, da samo dobro odrzavani, uredni i zdravi vinogradi, budu predmet istrazivanja, je dopunjen stavom o izvornosti vinograda. Ispostavilo se da su najpouzdaniji i najizvorniji vinogradi na pesku ili vezanom zemljistu, koji su ''zanavljani'' reznicama, te su tako na ''istom'' mestu 100 i vise godina! Zatiranje tragova o postojanju starih sorti u Vojvodini su ocigledni! Veliki problem i dalje predstavljaju razlicita suimena za jednu istu sortu u razlicitim krajevima, sto otezava njihovo prepoznavanje. Neke sorte e biti prepoznate u toku vegetacije 2010. godine, na osnovu slika i atlasa, koje istrazivaci ocekuju od kolega iz susednih zemalja!U toku drugog obilaska vinograda 2009. godine, istrazivaci su obrali groze sa obelezenih cokota, u odabranim vinogradima, i doneli ga na dalju obradu na Ogledno dobro Poljoprivrednog fakulteta u Sremske Karlovce. Deo uzoraka je ostavljen kod proizvoaca, da oni postupkom mikrovinifikacije proizvedu vina, nebi li se sto neposrednije ukljucili u ovo istrazivanje! Za te uzorke nepostoje podaci o sadrzaju seera i kiselina u grozu, jer ti proizovaci ne poseduju ureaje za njihovo odreivanje, ali istrazivaci su svesno isli na to. Nazalost, na nekim cokotima je bilo tako malo groza, zbog iznurenosti cokota, ili je pojedeno, da se nije mogao uzeti uzorak za vino. Sa 107 odabranih cokota je skinut 81 uzorak i donesen na obradu u poljsku laboratoriju u Sremske Karlovce. Postupkom mikrovinifikacije je proizvedeno 66 vina, jer su neki uzorci, zbog otezanog rada sa malim kolicinama, propali. Napravljena su vina od sorti moravka (frankovka), portugizac, prokupac, crna slankamenka, bela slankamenka, crvena slankamenka, kreaca (banatski rzling) i sedusa. Proizvedeno je 6 vina od uzoraka iz Stejanovaca i Riice, gde prepoznavanje sorti tek predstoji. Komisija, u istom onom sastavu kao za dodelu priznanja ''Najbolje iz Vojvodine'' je bila zadovoljna kakvoom uzoraka, a ocene su date u prilogu ovom izvestaju. Najbolje ocenjena vina su bila 1/1 uzorak prokupca iz Rivice sa 18,4 poena, sledi 1/3 uzorak portugizca iz Sr. Karlovaca sa 18,1 poena, 18/1 uzorak kreace iz Vrsca sa 18,0 poena, 22/1 uzorak bele slankamenke iz Berkasova sa 17,8 poena i td. Osnovni utisak ocenjivaca (komisije) je bio da je ovaj rad izuzetno vredan i da ga treba nastaviti.

''Program of Biotechnology Procedures for Diagnostic and Control of Trichinellosis in the Region of the Province of Vojvodina''

The research is about epidemiology and epizootiology of Trichinellosis based on the analyses on the reports from Vojvodina. In last 5 years in Vojvodina 39 occurrences of epidemics with 628 sick persons were reported. According to the topographic distribution the epidemics was reported in all the counties. The largest number of epidemics was in Srem county (9). Trichinellosis in Vojvodina occurs as an outbreak associated with the consumption of pork and pork products from pigs raised in back yards and slaughtered. Most frequently Trichinellosis is detected after the consumption of pork sausages. The outbreaks are seasonal, and the largest number occurs in winter time. In the region of Srem Trichinella-positive samples were detected by the method of compression: 88 pigs samples from 65 back yards, eight samples from wild boars and one from a horse. The largest number of Trichinellapositive animals was detected in Sid county. Since in the Province of Vojvodina about 2 million of pigs are slaughtered, this research included sera from pigs in intensive raising, i.e. from farms. A representative number of samples from 5 pig farms was examined using ELISA test and Trichinellosis was not detected. The samples from wild boars, from 4 locations, were examined and 15.4% were seropositive. References:

"Biological Effects of Insecticides Depending on Water Quality and the Storage Duration of the Spray Liquids"

The classification of water different in quality (neutral, alkaline and acid) and of significance for application in agriculture, was done. Physicochemical properties (pH and electro-conductivity) of insecticide (acetamiprid, metaflumizone and alpha-cypermethrin) spray liquids (SL) differently formulated (water soluble granules, concentrated suspension, emulsion concentrate) were determined, depending on the water quality and duration of their storage in the reservoir (immediately after preparation, after three and six days). Insecticidal effect was determined by biotest, and it differed subject to water quality and SL storage duration. After three and six days of SL storage, insecticidal effect increases compared to the SL applied immediately after preparation. This unusual alternation may result from metabolite formation which was validated by chemical analysis. By liquid chromatography method, it was established that acetamiprid and thiamethoxam content decreases, especially in alkaline water by aging, and metabolites - clothianidin and 6-chloronicotinic acid, were also detected. Duration of active ingredient and its metabolites activity in plants is not known, althought problems evidented in pollinating insects after their contact with plants in blossom whose seed was earlier treated by mentioned neonicotinoids, are known. Results were statistically processed. On the basis of the above presented, it can be concluded that standardization of water quality used for insecticide SL preparation is a necessity. In the light of this fact, duration of SL storage should be determined in order to preserve biological effect, improve their application quality, and all this in the function of helth safety of agricultural products and environment conservation.

"Bioloski efekti insekticida zavisno od kvaliteta vode i vremena cuvanja radne tecnosti"

Izvrsena je klasifikacija voda od znacaju za primenu u zastiti bilja razlicitih po kvalitetu (neutralna, kisela, alkalna). Odreena su fizicko-hemijska svojstva (pH i elektro provodljivost) radnih tecnosti (RT) insekticida (acetamiprid, metaflumizon i alfa-cipermetrin) razlicitih formulacija (vodorastvorljive granule, koncentrovana suspenzija, koncentrat za emulziju) zavisno od kvaliteta vode i duzine stajanja (odmah po pripremi, posle tri i sest dana) istih u rezervoaru. Biotestom odreen je insekticidni efekat, koji se razlikovao zavisno od kvaliteta vode i duzine stajanja RT. Stajanjem RT tri i sest dana poveava se insekticidni efekat u odnosu na RT primenjenu odmah po pripremi. Ova neuobicajena promena moze biti rezultat nastajanja metabolita sto smo potvrdili hemijskim analizima. Metodom tecne hromatografije konstatovano je da se sadrzaj acetamiprida i tiametoksama smanjuje starenjem RT najvise u alkalnoj vodi, a detektovani su i metaboliti -klotianidin i 6-hlornikotinska kiselina. Duzina dejstva aktivne materije i metabolita u biljkama nije nam poznata iako su nam poznati problemi koji su evidentirani kod insekata oprasivaca posle kontakta sa biljkama u cvetanju a prethodno je bilo seme tretirano pomenutim neonikotinoidima. Rezultati su statisticki obraeni. Na osnovu iznetog moze se zakljuciti da je neophodno normiranje kvaliteta vode za pripremu RT insekticida. Shodno tome odrediti i vreme stajanja RT u cilju ocuvanja bioloskog efekta, poboljsanja kvaliteta primene istih a sve radi zdravstvene bezbednosti poljoprivrednih proizvoda i ocuvanja zivotne sredine.

''Development of Superhard Nanocomposites''

Deposition of different types of nanocomposite and nanolayered coatings with a goal to produce superhard nanocomposites was made by different deposition processes: 1. ion beam assisted deposition (IBAD) and 2. plasma enhanced sputtering with high power pulse magnetron (HPPMS) were used. The application of an ion source allows a well controllable, reproducible and flexible deposition process. The ion flux, atom flux, ion energy, ion incidence angle, ion to atom arrival ratio and the substrate temperature were independently varied over a wide range. Thanks to the high pulsemodulation ratio, high-energy pulses lead to very high rates of ionization and plasma enhancement in HPPMS. Different materials were combined to produce coatings. Titanium and silicon targets together with nitrogen atmosphere were used to produce nanocomposite and nanolayered nc-TiN/a-Si3N4 coatings. Process parameters were varied to control the size of nanocrystals, and thickness of amorphous phase in nanocomposite coatings. Also by varying of process parameters thickness of individual layers in nanolayered coatings was controlled. Mechanical properties such as Young modulus of elasticity and hardness of coatings deposited on steel substrates were performed using nanoindentation technique. Morphology and microstructure were studied by using light optical microscopy (LOM), scanning electron microscopy (SEM), high resolution scanning electron microscopy (HRSEM) and transmission electron microscopy (TEM). Determination of crystal phases was conducted by using X-ray diffraction analysis (XRD and GIXRD). The composition of films was determined by using energy dispersive X-ray analysis (EDX). Surface topography of coatings was visualized by atomic force microscopy (AFM). Produced nanocomposite coating consisting of small crystallites (size of 5-10 nm) imbedded in thin amorphous matrix (2 nm thin) as well as nanolayered coatings whit modulation ratio in order of few nanometers, which will result in superior mechanical properties (superhardness, H > 40GPa, high elastic recovery > 80%), high chemical and temperature resistance References:

''Features of Ground Pepper Oleoresins Obtained by Classical and Supercritical Fluid Extraction with CO2''

Ground pepper oleoresins were extracted using hexane (oleoresin SX) and supercritical carbon dioxide, under the pressure of 150 (oleoresin SF 150), 200 (oleoresin SF200), 300 (oleoresin SF300) and 400 (oleoresin SF400) bars. In the present work all oreosines displayed an effective (p 0.05) scavenging activity against superoxide anion radicala, in a concentration-dependent manner. Obtained IC50, as the concentration of extract required for 50% scavenging of radicals under experimental conditions, were 4.42 mg/ml for oleoresin SX, 2.4 mg/ml for SF150, 4.14 mg/ml for SF200, 3.66 mg/ml for SF300 and 5.04 mg/ml for oleoresin SF400. condition. A smaller EC50 value corresponds to a higher antiradical activity. Antiproliferative activities of obtained oleoresins were investigated by measuring their cell growth effect on human tumor cell lines ­ HT-29 (colon adeno carcinoma) in the concentration range from 0.2 to 100 µl/ml. Oleoresin SX and SF400 inhibited significantly (p 0,01) the growth of HT-29 cells at the concentration higher than 70 µl/ml. The grouth of the cells were inhibited in the presence of all investigated oleoresins at the concentrations higher than 6 µl/ml and the concentrations of 50 µl/ml of oleoresin SX showed antiproliferative effect of 60%. Beside antiproliferative effect of oleoresins on HT-29 cell line, the growth stimulation of these cells was observed in the presence of SF200 i SX oleoresins applied at the lowest concentarions.

''Development and Structure Design of Polymeric Materials''

Thermal degradation of poly(urethane-isocyanurate) networks and segmented polycarbonate-based polyurethanes was investigated by nonisothermal thermogravimetry analysis, using TG-MS and SDT methods. Viscoelastic and damping properties of polyurethanes obtained using different network precursors were estimated by dynamic mechanical measurements. Modulated differential calorimetry was used to investigate thermal behavior of segmented polyurethanes, synthesized using one-step technique. Fourier transform infrared spectroscopy was used to investigate the hydrogen bond formation and chemical structure of prepared segmented polyurethanes. The investigation of the influence of hard segment content on morphology and surface topography of prepared segmented elastomers sheets was done by atomic force microscope. In order to determine the degree of cristallinity and to evaluate the dispersion of montmorillonite and bentonite in the polyurethane matrices, the prepared samples were characterized by wide angle X-ray scattering. Curing kinetics of alkyd resins based on castor oil and dehydrated castor oil with melamine resin have been studied by DSC method with programmed heating. The results determined from dynamic DSC curves were mathematically transformed using Ozawa isoconversional method for obtaining the isothermal data. Effects of chromium active centers distribution on silica on the polymerization of ethylene were analysed. The effect of nanoparticles on the mechanical properties, thermal ageing and gama­radiation resistance of elastomeric materials based on different network precursors were assessed. References:

Biogas. During the monitoring of the 10 biogas plants, more than 100 parameters were collected at each biogas plant, and consequently relevant criteria for efficiency assessment are chosen. Prerequisites for the selection were: data availability, measurement and calculation simplicity, coverage of all aspects of biogas production. Relative methane yield and methane productivity are describing efficiency of the process of biogas production. Utilization ratio of CHPU and degree of methane utilization are describing the efficiency of biogas utilization. Specific GHG emissions and cumulated energy demand are environmental figures, and profit and labor input are economic criteria. Methodology for efficiency assessment of biogas plants is based on two methods: AHP (Analytic Hierarchy Process) and SAW (Simple Additive Weighting). The first one is used for determination of relative weights (importance of criteria), and the second is applied for weighing of values of criteria, and overall utility is calculated. Consequently, biogas plants are ranked, and insight in reasons for (in)efficiency is possible, wherewith it is possible to define ranges for criteria that enable efficient operation of biogas plants. Biodiesel. In the initial stage of the project the production phases of biodiesel life cycle chain and the relevant processes in terms of their environmental impacts were defined. A flow chart diagram was selected which represents the typical elementary material and energy flows of biodiesel production practice in Vojvodina. Data on elementary flows are organized in 11 impacts category each representing one particular aspect of environmental protection. Human health, ecosystem quality and non-renewable energy depletion represent the three areas of protection which were used as reference for the quantification of the environmental impact of biodiesel production. The results confirm the positive energy balance of biodiesel, but emphasize the large variation in the results depending on the implemented methodological approach and assumptions considered Nanostrucures. The low temperature magnetization was analyzed in thin films. In published papers was exposed discussion conserning "physical and non-physical states" in last 30 years. This problem was solved by Dyson which has shown that two excitations at one lattice point give extremely low (exponential) contribution to magnetization. This Dyson's proof is not applicable for thin magnetic films where exponentially small contributions appear even in harmonic approximation. In these structures the correct expression for low temeperature magnetiyation can be obtained by means of exact Boze repesentation of spin operators. It was subject of published papers.

Svi predvieni ciljevi su realizovani. Biogas. Tokom monitoringa 10 postrojenja, sakupljeno je oko 100 parametara po postrojenju iz kojih su definisani i izabrani kriterijumi kojima moze da se oceni efikasnost rada biogas postrojenja. Preduslovi za odabir pokazatelja bili su: dostupnost podataka; tacnost merenja i jednostavnost izracunavanja; pokrivenost svih aspekata proizvodnje biogasa. Relativni prinos metana i produktivnost metana opisuju efikasnost procesa proizvodnje biogasa, a iskorisenje kapaciteta i iskorisenje energije sadrzane u metanu efikasnost iskorisenja biogasa. Emisije gasova koji doprinose efektu staklene baste i akumulirana potreba za energijom predstavljaju ekoloske, a profit i ulozeni rad ekonomske pokazatelje. Ocena efikasnosti biogas postrojenja zasniva se na dve metode: AHP (Analytic Hierarchy Process) i SAW (Simple Additive Weighting). Prvom se dobijaju relativne tezine, tj. vaznosti kriterijuma, a u drugoj su one primenjene na vrednosti kriterijuma i izracunata je ukupna korisnost. Zatim su biogas postrojenja rangirana, a mogu je i uvid u razloge (ne)efikasnosti, cime su definisani opsezi kriterijuma koji omoguuju efikasan rad. Biodizel. Definisane su faze i kvantitativnom metodom su utvreni relevantni procesi u zivotnom ciklusu biodizela sa stanovista zastite zivotne sredine. Sastavljen je dijagram elementarnih materijalnih i energetskih tokova osnovnih procesa pri proizvodnji biodizela koji oslikava proizvodnu praksu u uslovima Vojvodine. Prikupljeni podaci o elementarnim tokovima grupisani su u 11 kategorija uticaja koji pokrivaju pojedine aspekte zastite zivotne sredine. Ljudsko zdravlje, kvalitet zivotne sredine i korisenje neobnovljivih resursa su odreeni kao tri oblasti zastite preko kojih se iskazuje uticaj proizvodnje i primene biodizela na zivotnu sredinu. Rezultati potvruju pozitivan energetski bilans biodizela, ali i ukazuju na veliku varijaciju u dobijenim rezultatima u zavisnosti od primenjenog metoda proracuna i uzetih pretpostavki. Nanostrukture. Analizirana je niskotemperaturska magnetizacija u strukturama sa narusenom simetrijom. U objavljenim radovima je izlozena tridesetogodisnja problematika fizickih i nefizickih stanja pri zameni spinskih operatora Boze operatorima koja se odnosila na idealnu strukturu. Ispostavilo se da se rezultati ovih istrazivanja ne mogu primeniti na strukture sa narusenom simetrijom pa je formulisan model koji za ovakve strukture daje ispravne rezultate. Posto u Srbiji jos uvek ne funkcionise ni jedno biogas postrojenje poseban znacaj dat je prenosenju iskustava iz inostranstva od onih koji se time ve duze bave. Ostvareni su brojni kontakti i razmena informacija u Srbiji, Sloveniji, Austriji, Hrvatskoj, Nemackoj i Maarskoj, sa kolegama iz inostranih instituta i preduzea koja proizvode i eksploatisu biogas potrojenja od sirovina iz poljoprivrede. Zahvaljujui afirmaciji stecenoj prikazom u javnosti rezultata rada na ovome projektu, rukovodilac projekta ucestvovao je u znacajnim aktivnostima u zemlji i inostranstvu u oblasti unapreenja koriscenja obnovljivih izvora energije.

''Istrazivanje i realizacija novih resenja energetskih pretvaraca u industrijskim elektromotornim pogonima''

U petoj godini rada na projektu, a u skladu sa postavljenim ciljevima za ovu godinu istrazivanja, istrazivaci su se bavili novim resenjima energetskih pretvaraca u slozenim elektromotornim pogonima i u sklopu obnovljivih izvora elektricne energije. Energetski pretvraci u elektromotornim pogonima su vezani za napredna resenja kod pogona trofaznih i visefaznih elektricnih masina. Dva tipa pretvaraca u posebno usavrsavana u ovom periodu. Nastavljena su istrazivanja iz prethodnog perioda, s tim sto je paznja je usmerena ka novim resenjima za petofazne i sedmofazne pogonske masine. Sa industrijskim partnerima napravljani su preliminarni projekti za izradu prototipova petofazne i sedmofazne elektricne masine. Uraene su i odreene modifikacije na ranije realizovanom sestofaznom invertoru u cilju prosirenja mogunosti korisenja ovog pretvaraca za eksperimente u elektromotornim pogonima sa petofaznim i sedmofaznim masinama. Realizovani energetski pretvarac back-to-back topologije za povezivanje visefaznih masina u generatorskom radu na elektricnu mrezu, unapreen je kroz usavrsavanja i modifikacije konstrukcije i upravljacko-regulacionog sistema.

''Implementation of RFID Technology in Supply Chains (Implementation of Automation Systems in Logistics)''

According to the proposed research plan, the researchers have accomplished the required tasks. As the research topic is very interesting, great amount of researchers' energy is devoted to spreading the knowledge about RFID technology, both to economy participants, and to the students who get acquainted with the identification technologies in various teaching subjects. The continuation in research has also brought cooperation continuation with ZZ VI-agra from Vrbas, which has enabled gaining of the required data for designing and analysis of RFID system model for identification of big cattle, based on RFID tag application. The cooperation with the company Rumaplast from Ruma has been continued in implementation of RFID technology. Furthermore, the company L.A.B.B. group from Sid has allowed access to the logistic part of the system where RFID technology has been implemented, which resulted in the analysis of the system's functioning and improving of IML robot grasping process. The researchers from the Electrotechnical faculty in Istocno Sarajevo have continued with work on software development, which accompanies the continuation in research. Also, Agricultural faculty from Sarajevo has joined the research by taking the required preparations for RFID technology implementation at the farms in Bosnia and Hercegovina. These activities are necessary for development of the system for identification of livestock, which will not only be bred, but also imported to/exported from Bosnia and Hercegovina, so it is also necessary to provide the compatibility of both the identification system and the data available to the system users.

''Tehnologija proizvodnje hrane za zivotinje, bezbedna za zivotinje, ljude i okolinu''

Postupkom ekstrudiranja hraniva u proizvodnji hrane za zivotinje i ljude obezbeuje se visok kvalitet ekstrudiranih hraniva kako u nutritivnom, tako i higijenskom kvalitetu. Rezultati ekstrudiranja kukuruza, kukuruznog loma, kukuruznog stocnog brasna, razi, sojinog zrna, uljane repice, sacme uljane repice i mesavine sacme uljane repice sa kukuruzom potvrdili su da ekstrudiranjem hraniva biljnog porekla dolazi do poveanja njegove nutritivne vrednosti, poveanja iskoristljivosti skroba, proteina i ulja a smanjenja sadrzaja vlage i antinutritivnih materija i poboljsanja senzornih karakteristika. Ekstrudiranjem se smanjuje sadrzaj mikroorganizama, narocito plesni, cime se obezbeuje higijenska ispravnost hraniva namenjenih za ishranu zivotinja i ljudi. Ispitan je kvalitet pileeg mesa dobijenog ishranom pilia sa razlicitim ekstrudiranim proizvodima uljane repice i ekstrudiranim kukuruznim stocnim brasnom i utvreno je da je kvalitet mesa ujednacen za ovakvu kategoriju zivotinja i da je visoke nutritivne vrednosti. Istrazivanja su obuhvatila mogunost primene lekovitog i aromaticnog bilja u odrzivoj proizvodnji hrane za zivotinje. Biogeni aditivi, koji predstavljaju mesavinu lekovitih aromaticnih biljaka i etericnih ulja u ishrani zivotinja, povoljno deluju na njihovo zdravlje u nekoliko pravaca: kao antioksidanti, poboljsivaci metabolizma, kontrolori rasta i razvoja patogenih mikroorganizama, ukljucujui dejstvo na plesni i bakterije. Delovanje etericnih ulja na zdravlje i performanse zivotinja, provereno je kroz bioloski ogled sa piliima.

''Continued Examinating of Tisa Eco-sistem in Martonos Senta Sector in 2009''

From 20 May 2009 to 25 November 2009 the water quality of the River Tisa was monitored on weekly bases in Martonos-Senta sector, on the Keres Brook, Madaras Canal and Kocis Canal. From April there was a change in the ecosystem of the Keres Brook. The wastewater from the city of Subotica was discharged into the Tisa over Madaras Canal about 1,000 m upstream from Kanjiza. Thus the load of the Keres Brook was cut off downstream from Ludos Lake and the fishpond of Kapetanski Rit.From October the wastewater from Subotica was again discharged into the Tisa via Keres, which was seen in a drastic drop in water quality of the Keres Brook. Madaras Canal water was still polluted since wastewater from paprika processing in Martonos was being discharged into the canal.The source of poisoning of the Tisa regarding the factory of Alltech-Fermin was solved by setting up a new facility for wastewater treatment within the plant. Apart from the investigation plan, the flora of the Tisa was explored in the summer period when during the low water and slow flow due to Becej Dam the river took the characteristics of stagnant water. In the analyses of mineral composition of apples and pears grown in the flooded area of the Tisa it was established the increased concentrations of Cd, Cu and Pb were above MDK in both fruits.

''Kontinuirano ispitivanje ekosistema reke Tise na deonici Martonos-Senta u 2009. godini''

Od 20. 05. do 25. 11.2009 nedeljno je praen kvalitet vode reke Tise na relaciji od Martonosa do Sente, potoka Keres te kanala Madaras i Kocis. Od aprila meseca doslo je do promene u ekosistemu potoka Keres. Otpadna voda iz Subotice pustena je preko kanala Madaras u Tisu oko 1000 m uzvodno od Kanjize. Na taj nacin je preseceno optereenje potoka Keres nizvodno od Ludoskog jezera i ribnjaka na Kapetanskom ritu. Od oktobra meseca otpadna voda iz Subotice ponovo se ispusta u Tisu preko potoka Keres sto se uocava u drasticnom pogorsanju kvaliteta vode potoka Keres. Kanala Madaras i dalje je izuzetno zagaen zbog ispusta otpadne vode iz pogona za preradu paprike u Martonosu.Izvor zagaenja Tise od strane fabrike Alltech ­ Fermin je eliminisan pustanjem u pogon novog precistaca otpadne vode u okviru samog pogona. Mimo plana istrazivanja ispitana je flora Tise u letnjem periodu kada usled niskog vodostaja i usporavanja toka sa strane brane kod Beceja reka poprima karakteristike stajae vode.Analizom mineralnog sastava jabuke i kruske uzgajanih na plavnom podrucju Tise utvreno je poveanje koncentracije Cd, Cu i Pb i u jabuci i u krusci iznad MDK.

"Further Development and Study of in the Domain of Sensored and Powered Artificial Multi-link Foot with Ankle of Humanoid Robots"

According to the project research agenda all the planned tasks have been fulfilled completelly. Besides the sensor static characteristics, their dynamic characteristics were also thoroughly tested. It has been demonstrated that the sensors are fast enough not only for measuring ground reaction forces during normal walk, but also in case of abrupt distrubances. In the period that follows the development of the walk control algorithm is planned. This algorithm should not concentrate only on the ankle joint but also on another joint in order to efficiently react to an abrupt disturbance ­ a horizontal impact. The feedback should be taken only from the measured ground reaction force components. References:

"Realization of High Performance Micro-Sensors for Operation in Extreme Environmental Conditions"

The most important result achieved within this project is realization of a sensor for measuring water concentration (or moisture) in buliding materials. The cost-effective sensor was fabriacted in PCB (Printed Circuit Board) technology. The sensor has an innovative design (for the first time capacitive prt and inductive part of the sensor have been realized in one metal layer), it is wireless and without an internal power supply such as battery. After succesful fabrication, the sensor was embedded in test material samples in our case clay brick and autoclaved aerated concrete block. Anntena coil was placed around the sensor and moisture or internal water content of the samples could be monitored with antenna by tracking the changes in the sensor's resonant frequency using HP-4194A Impedance/Gain-Phase Analyzer. When the sensor was exposed to increased water concentration, dielectric constant of the capacitance of the LC circuit was increased, thus increasing capacitance and decreasing the sensor's resonant frequency. The sensor was successfuly tested for continual monitoring of water content in clay brick and autoclaved aerated concrete block. References:

"Realizacija mikro-senzora visokih performansi za rad u ekstremnim uslovima okruzenja"

Najznacajniji rezultat postignut u okviru ovog projekta predstavlja realizacija senzora za merenje koncentracije vode (odnosno vlage) u graevinskim materijalima. Fabrikovan je jedan jeftini senzor u PCB (Printed Circuit Board) tehnologiji. Realizovani LC senzor ima inovativni dizajn (gde su po prvi put kapacitivni deo i induktivni deo senzora realizovani kompletno u jednom metalnom sloju) i bezican je, a za svoj rad ne zahteva nikakvo baterijsko napajanje. Nakon fabrikacije senzora izvrseno je njegovo tesitranje tako sto je postavljen u uzorak graevinskog materijala koji se ispituje, u nasem slucaju - obicna cigla i siporeks blok. Oko senzora je postavljen jedan antenski namotaj i koncentracija vlage odnosno apsorbovane vode je praena preko ovog antenskog namotaja i merena je rezonantna ucestanost senzora korisenjem instrumenta HP-4194A Impedance/Gain-Phase Analyzer. Izlaganje senzora veoj koncentraciji vlage je poveavalo dielektricnu konstantu kapacitivnog dela senzora, a time i njegovu kapacitivnost odnosno dolazilo je do smanjivanja rezonantne ucestanosti senzora. Fabrikovani senzor je uspesno testiran za kontinualno posmatranje procenta vlage u graevinskim materijalima kao sto su glinena cigla i siporeks blok.

''Functional Properties of Tailor-Made Fat for Bakery and Confectionery Products''

Physical properties of different tailor made margarines for puff pastry were determined. Physical properties are important parameters which determine use of margarine, dough processing and quality of end product. Margarines which are used in the process of lamination should posses specific properties such as: wide interval of plasticity over temperature, to be easily processed in order to form homogenous and continual fat layers. Layers formed within dough should resist thinning in laminator and water vapor pressure during baking without bursting. Physical properties were determined as hardness by penetration method. Rheological properties were defined by flow curves, from which parameters such as flowability and spreadability were calculated. Five different samples of margarine were tested and all of them exhibited thyxotropic behavior. Kinetics of crystallization my means of crystal seed development, growth of crystals and formation of final fat structure were determined by various methods. In these way number, size, shape and polymorphism could be predicted. Fat fillings are suspension of particles in fat as continuous phase. Percentage of fat in filling is rather high (30-40%) so it determines properties of filling such as consistency, melting and hardening. Partial substitution of fat in confectionery filling was done by maltodextrin-product of starch hydrolysis which is known to be fat substitute. In order to define sensory properties of food by objective methods instrumental textural measurements were done. Influence of two different maltodextrins on hardness and adhesives of confectionery filling as parameters of spreadability were measured. Maltodextrin increased hardness and adhesives which means that fillings with addition of maltodextrin were less spreadable. The possibility of development of spread made from hull-less pumpkin flour and higholeic sunflower oil in order to develop high nutritive and functional product were looked into. References:

"Funkcionalnost namenskih masti za pekarske i konditorske proizvode"

Odreivane su fizicke karakteristike razlicitih namenskih margarina za lisnata testa. Fizicke karakteristike bitan su parametar koji utice i definise obradu testa i kvalitet lisnatog paciva. Margarini koji se koriste pri procesu laminiranja treba da zadovolje odreene funkcionalne karaktristike: da imaju sirok interval plasticnosti u funkciji temperature, da se lako obrauju i formiraju homogene u kontinualne slojeve koji se na cepaju pri visestrukom istanjuvanju tokom laminiranja i pritisku vodene pare tokom pecenja. Fizicke karakteristike odreene su kao cvrstoa metodom penetracije. Reoloske karakteristike definisane u metodom krive proticanja, iz kojih se dobijaju parametri mazivosti i tecljivosti. Ispitano je pet razlicitih margarina i utvreno da svi pokazuju tiksotropan nacin proticanja. U zavisnosti od sastava cvrstih triglicerida margarini su imali razlicite reoloske parametre koji su definisani racunski. Ispitivana je kinetika nastajanja kristalizacionih jezgara, rasta kristala i formiranja konacne strukture masti u cilju kontrolisanja broja, velicine, oblika i polimorfa kristala. Masna punjenja predstavljaju suspenziju masne kontinualne faze u koju su uklopljene cvrste cestice. Sadrzaj kontinualne faze, odnosno masti je visok (30-40%) tako da u potpunosti odreuje osobine masnog punjenja (konzistenciju, brzinu topljenja, i ocvrsavanja). Masti za konditorske proizvode ispitane su formiranjem masnog punjenja kod koga je deo masti zamenjen skrobnim hidrolizatommaltodekstrinom. Teksturometrijska merenja su izvedena u cilju definisanja senzornih karakteristika hrane instrumentalnim metodama i objektivnim testovima. Ispitan je uticaj koncentracije dve vrste maltodekstrina na cvrstou i adhezivnost masnog punjenja koji definisu osobine mazivosti prilikom primene. Utvreno je da dodatak maltodekstrina poveava cvrstou i da je ovaj efekat koncentracciono zavistan. Masna punjenja sa dodatkom maltodekstrina imala su vee vrednosti adhezivnosti tj. bila su slabije maziva. Takoe ispitana je mogunost dobijanja namaza od brasna dobijenog mlevenjem pogace semena tikve golice uz ododatak ulja visokooleinskog suncokreta. Ovako dobijeni namaz poseduje povoljne nutritivne i funkcionalne karakteristike.

"Molecular Physiology of Leydig Cells in Stress Response"

Potential health risks associated with non-therapeutic use of anabolic-androgenic steroids (AAS) by large number of healthy individuals believed to be high. Despite popular interest in AAS, we still lack a broad understanding of mechanisms involved in AAS-affected biosynthesis of steroid hormones in vivo. In order to mimic the most likely route of human exposure, groups of adult male rats were androgenized with testosterone-enanthate (5 mg/kg bw) for one day and two weeks, as well as with two doses (5 or 25 mg/kg bw) for two months. Leydig cells isolated from control and androgenized rats used to follow the expression and activity of the steroidogenic machinery. Obtained results showed that both types of prolonged exposure to testosterone-enanthate decreased the expression of Sr-b1, Tspo, Star, Cyp11a1, Cyp17a1 in Leydig cells from androgenized rats. Oppositely, the expression of Hsd3b, Ar and Pde4 was increased. Androgenization for two weeks inhibited Cyp19 transcription, while two months exposure caused opposite effect. The expression of Lhr was affected only with two months treatment. Steroidogenic capacity and in vitro production of cAMP and androgen declined, while progesterone and estradiol production was stimulated. Taking together, exposure of adult male rats to supraphysiological doses of testosterone-enanthate strongly disturbed the steroidogenic machinery in Leydig cells, probably trough increased Ar expression.

"Molekularna fiziologija Leyding-ovih elija u odgovoru na stres"

Siroko rasprostranjena upotreba anabolika-androgenih steroida (AAS) od strane zdravih osoba (pogotovo u populaciji koja upraznjava "feetnes" ili pak AAS koristi u kontraceptivne svrhe) predstavlja potencijalnu opasnost po zdravlje. Iako je poznato da AAS inhibisu gonadalnu steroidogenezu, precizni efekti njihove upotrebe kao i potpuno razumevanje mehanizama preko kojih AAS remete biosintezu steroidnih hormona jos uvek nedostaje. Da bi imitirali najcese korisen nacin upotrebe AAS od strane zdravih ljudi, adultni muzjaci pacova su tretirani sa testosteron-enantom (5 ili 25 mg/kg bw) jedan dan, dve nedelje ili dva meseca. Dobijeni rezultati su jasno pokazali smanjen steroidogeni kapacitet izolovanih Leydigovih elija u uslovima produzenog tretmana kao i smanjenu gensku ekspresiju elemenata steroidogeneze: Sr-b1, Tspo, Star, Cyp11a1, Cyp17a1. Nasuprot tome, ekspresija 3Hsdb, markera steroidogene aktivnosti Leydig-ovih elija je bila stimulisana. Takoe, produzeni tretman je indukovao ekspresiju Ar i Pde4, odgovorne za hidrolizu cAMP-a u Leydigovim elijama. Dvo- nedeljni tretman je inhibisao transkripciju Cyp19 dok je dvo-mesecni imao suprotan efekat. Generalno posmatrano dobijeni rezultati su pokazali da dvo-mesecni tretman pacova sa testosteron-enantom i inhibise ex vivo produkciju cAMP i androgena dok je produkcija progesterone i estradiola bila stimulisana.

"The Adaptation of the Germanium Detector Active Shield for Low Energy Gamma Region"

Several gamma spectra of big volume germanium detector are acquired. Gamma lines emitted after neutron capture, as well as after inelastic scattering on the germanium crystal were detected and then analyzed. The thermal and fast neutron fluxes were calculated and their values were compared for the two different kinds of detector shield. Several materials having different neutron slowing-down properties were packed in Marinelli geometry, positioned on the lead shielded detector and measured for around 106 s. The main goal was to estimate a possible influence of the sample on the intensity of the neutron induced Ge gamma lines. During the first tests of coincident operating mode of germanium detector and plastic scintillator the coincident spectra without any sample inside lead shield are acquired. By analyzing of these spectra, it is possible to found which part of muon spectrum is mainly responsible for certain events registered in coincident spectrum of Ge detector. We completed the necessary NIM modules for design of fast coincidence circuit based on big plastic scintillator , small plastic scintillator and Ge detector for analysis of muon induced reactions.

"Transition Metal Complexes with Some Schiff Bases and Pyrazole Derivatives"

The new metal complexes with some Schiff bases and mono-, bi- and tridentate pyrazole derivatives were synthesized and their physico-chemical and structural characteristics were analyzed. Thus, the tridentate NNN Schiff base 2-acetylpyridine S-methylisothiosemicarbazone (HL) gave two structurally very interesting monomeric and one dimeric copper(II) complex of the formulas [Cu(HL)SO4(H2O)]·H2O (1), [Cu2(HL)2(mi-SO4)2]·2H2O (2) and [Cu(HL)(NCS)(SCN)] (3). The common characteristic of all three complexes is their square-pyramidal structure with the neutral HL ligand in the basal plane. In the case of monomeric complexes 1 and 3, the appical position is occupied by the oxygen atom from the monodentate SO4 group or sulfur from the ambidentate NCS group. In the centrosymmetrical dimer 2, oxygen atoms from both bridging SO4 groups, beside the equatorial, are occupying also the apical positions in both coordination polyhedra. In addition to the complexes, the X-ray analysis of the protonated ligand form HIHI was carried out. Also, with tridentate ONO Schiff bases, semicarbazones of pyridoxal (PLSC) and 2(diphenylphosphino)benzaldehyde (SCPPh2), respectively, the complexes of V(V) and Ni(II) were obtained with square-pyramidal and square-planar structures of the formulas NH4[VO2(SCPL-2H)] and [Ni(SCPPh2-H)N3]. Here it is worth mentioning that the isolated complex of Ni(II) with SCPPh2 is the first complex ever described with semicarbazone ligand containing phosphorus atom as ligating one. Finally, among the Schiff base complexes, the square-planar Cu(II) compound with tridentate ONN pyridoxalaminoguanidine ligand (PLAG) of the formula [Cu(PLAG)MeOH](NO3)2 was obtained, in which the pyridoxal moiety of this ligand is in the form of a zwitter ion. Among the metal complexes with ligands pyrazole derivatives, the tetrahedral complexes of Zn(II) and Hg(II) with monodentate 4-acetyl-3-amino-5-methylpyrazole (aamp) of the formulas [Zn(NCS)2(aamp)2] and (aampH)2[Hg(SCN)4] were obtained and characterized by structural and physico-chemical analyses. With 3,5-dimethylpyrazole-1-carboxamidine (HL) as bidentate NN ligand, two monomeric and one dimeric octahedral complex of Cd(II) of the formula [Cd(HL)X2] (X=Cl, Br) and [Cd2(HL)4(miCl)2](NO3)2, respectively, were synthesized and characterized by various methods. The same ligand with zinc(II) forms a very deformed pentacoordinated complex (tau=0.55) of the formula [Zn(HL)2Cl]NO3. Finally, copper (II) and nickel (II) formed the complexes with the in situ prepared NNO N,N-bis(4acetyl-5-methylpyrazole-3-yl)formamidine of the formula M(ampf)(NO3)2x2MeOH which were also characterized by various physico-chemical methods.

Tako, sa tridentatnom NNN Sifovom bazom S-metilizotiosemikarbazonom 2-acetilpiridina (HL) dobijena su strukturno vrlo zanimljiva dva monomerna i jedan dimerni kompleks bakra(II) formula [Cu(HL)SO4(H2O)]·H2O (1), [Cu2(HL)2(mi-SO4)2]·2H2O (2) i [Cu(HL)(NCS)(SCN)] (3). Zajednicko za sva tri kompleksa je da imaju kvadratno-piramidalnu strukturu sa neutralnim ligandom HL u bazalnoj ravni. U slucaju monomernih kompleksa 1 i 3 u apikalnom polozaju se nalazi atom kiseonika monodentatne SO4 grupe, odnosno atom sumpora ambidentatne NCS grupe. U centrosimetricnom dimeru 2 atomi kiseonika obe mostovne SO4 grupe, osim ekvatorijalnih, zauzimaju i apikalne polozaje u oba koordinaciona poliedra. Pored kompleksa, uraena je i rentgeno-strukturna analiza (RTG) protonovane forme liganda HI HI.

Ovde je vazno napomenuti da izolovani kompleks Ni(II) sa SCPPh2 predstavlja prvi kompleks uopste sa semikarbazonskim ligandom koji kao jedan od ligatora sadrzi atom fosfora. Na kraju, od kompleksa sa Sifovim bazoma dobijen je i sa RTG okarakterisan kvadratno-planarni kompleks Cu(II) sa tridentatnim ONN piridoksalaminogvanidinom (PLAG) formule [Cu(PLAG)MeOH](NO3)2, u kojem se piridoksalni ostatak ovog liganda nalazi u obliku zwitter-jona. Od kompleksa metala sa ligandima derivatima pirazola sintetizovani su i fizicko-hemijski i strukturno okarakterisani tetraedarski kompleksi Zn(II) i Hg(II) sa monodentatnim 4-acetil-3-amino-5metilpirazolom (aamp) formula [Zn(NCS)2(aamp)2] i (aampH)2[Hg(SCN)4]. Sa 3,5-dimetilpirazol-1-karboksamidinom (HL) kao bidentatnim NN ligandom, sintetizovani su i razlicitim metodama okarakterisana dva monomerna i jedan dimerni oktaedarski kompleks Cd(II), formula [Cd(HL)X2] (X=Cl, Br); [Cd2(HL)4(mi-Cl)2](NO3)2. Isti ligand sa cinkom(II) daje jako deformisani pentakoordinovani kompleks (tau=0,55) formule [Zn(HL)2Cl]NO3. Na kraju, sa bakrom(II) i niklom(II) sintetizovani su i fizicko-hemijski okarakterisani kompleksi sa in situ dobijenim tridentatnim NNO N,N-bis(4-acetil-5-metilpirazol-3-il) formamidinom (ampf) opste formule M(ampf)(NO3)2x2MeOH.

"Development of Chemical Methods of Analysis of Neonicotinoids and Pyridine-Carboxilic Acid Derivatives"

In the area of the development of methods for detection and determination of neonicotinods by voltammetric method, the following investigations were carried out: With the aim of choosing the right working electrode, voltammetric study of selected neonicotinoid insecticides was carried out on the different carbon-based electrodes, namely: carbon-paste electrode, glassy carbon electrode, and glassy carbon electrode modified in situ by bismuth film. Preliminary experiments have been performed to apply antimony-film electrode for the determination of trace metals. A voltammetric method has been developed for the determination of thiametoxam using tricresyl phosphate-based carbon paste electrode. Further, a rapid derivative spectrophotometric method has been developed for the determination of imidacloprid in the presence of 6-chloronicotinic acid, the method being suitable for the analysis of commercial formulations. In the photocatalytic degradation of clopyralid and picloram with the catalysts TiO2 Degussa P25, and TiO2 Wackherr under UV irradiation the effect of temperature on the reaction kinetics was studied in the temperature range of 25-50 ºC. It was found that in all cases the reaction was fastest at 25 ºC. Besides, the degradation rate of clopyralid was studied in the presence of TiO2 (anatase) undoped and doped with nitrogen, as well as of TiO2 (rutile) undoped and doped with the different amounts of iron (0.13-1.48 at.%), applying visible light as the radiation source. It appeared that the degradation rate was higher with nitrogen-doped TiO2 (anatase) compared to undoped TiO2, whereas in the case of TiO2 (rutile) the highest degradation rate was achieved using TiO2 doped with the highest iron content. In all cases, the degradation kinetics was followed by HPLC­DAD and spectrophotometry. Finally, photocatalytic efficiency of AlFe-pillared clay and Fe-ZMS-5 catalyst was examined in the degradation of imidacloprid in water. The results were compared with those obtained using the photoFenton reaction and TiO2 Degussa P25. References:

Razraena je voltamterijska metoda odreivanja tiametoksama primenom elektrode od ugljenicne paste na bazi trikrezil-fosfata. Nadalje, razraena je brza derivativna spektrofotometrijska metoda za odreivanje imidakloprida u prisustvu 6hlornikotinske kiseline koja je pogodna za analizu sastava komercijalnih formulacija. U fotokatalitickoj razgradnji klopiralida i piklorama uz katalizatore TiO2 Degussa P25, odnosno TiO2 Wackherr i UV zracenje proucavan je uticaj temperature (25-50 ºC) na kinetiku reakcije.

Pokazalo se da je brzina razgradnje vea primenom TiO2 (anataze) dopovanog sa azotom u odnosu na nedopovan TiO2, dok je u slucaju TiO2 (rutil) brzina razgradnje najvea u prisustvu TiO2 dopovanog sa najveim sadrzajem gvoza. U svim slucajevima kinetika razgradnje je praena primenom HPLC­DAD i spektrofotometrijski.

"Technology of Obtaining and Characterization of Amorphous Semiconductors"

Studies of complex amorphous semiconducting systems were continued. One of the objectives that has come out from previous investgations was concerned with the measurement of electrical conductivity in DC and AC regimes. An appropriate modification of the method for determining electric properties of high-resistance semiconductors was carried out while paying special attention to the exprerimental set-up and computational methodology to eliminate the parasitic effects on the measured quantities. On the basis of a theoretical analysis and experimental AC measurements a conclusion has been drown that there is a marked influence of parasitic capacitance and parallel resistance in the measurement of highresistance samples. These parasitic effects are a consequence of the instrument adapter and temperature chamber. It appeared that the effect of parasitic capacitance was more pronounced than the parallel resistivity, and parasitic effects influence more the real part of dielectric permitivity than the impedance itself. A simple numerical technique was proposed to compensate for the parasitic effects in the concrete high-resistance semiconducting glasses. Detailed studies of the frequency dependence of dielectric parameters of bismuth glasses were carried out in the 1 kHz-1 MHz interval at the corresponding temperatures. The results, interpreted in terms of the Debye theory of molecular dipoles, indicated the existence of diversity in the types of dipoles that determine dielectric behavior of a given glass. The Cole-Cole diagrams allowed the determination of several dispersion parameters that describe closer the phenomenon of dielectric relaxation in the lowand high-temperature regions. Based on the Erying theory of chemical reaction rate it was possible to determine the enthalpy H and activation energy of dipole relaxation F. The results indicated the existence of distribution dipole relaxation times and different sources of dipoles in low- and hightemperature regimes. It was found that the polaronic mechanism is responsible for a significant increase in the dielectric constant at higher temperatures. For the Cu-containing systems, the DC and AC conductivitis were measured in the frequency interval of 102-106 Hz from 300 K to the temperture of 398 K. The increase in Cu content enhanced the conductivity and decreased the activation energy. The quest for finding a best method to calculate dispersion of the refraction index of thin films has continued. It was found that certain corrections are needed in the application of the Cheremukhin method to monolayer and multilayer amorphous systems. Detailed studies of optical characteristics of semiconductors doped with rare earth elements are in progress. References:

"Tehnologija dobijanja i karakterizacija neureenih poluprovodnika"

Nastavljena su istrazivanja slozenih sistema amorfnih poluprovodnika. Jedan od ciljeva proistekao iz dosadasnjih istrazivanja bio je usmeren na razlicita merenja elektricne provodljivosti u rezimu jednosmerne i naizmenicne struje. Izvrsena je odgovarajua modifikacija metoda za odreivanje elektricnih svojstava visokootpornih poluprovodnika pri cemu je posebna paznja posveena eksperimentalnoj postavci i racunskoj metodologiji za eliminisanje uticaja parazitnih efekata na merene velicine. Na osnovu teorijske analize i eksperimentalnih AC merenja doslo se do zakljucka da postoji izrazen uticaj parazitne kapacitivnosti i paralelne otpornosti prilikom merenja uzoraka visoke elektricne otpornosti. Ti parazitni efekti su posledica neminovnog uticaja adaptera instrumenta i temperaturne komore. Pokazano je da je uticaj parazitne kapacitivnosti izrazeniji nego paralelne otpornosti, kao i da parazitni efekti vise uticu na realni deo dielektricne permitivnosti nego na samu impedansu. Predlozena je i jednostavna racunska metoda kompenzacije parazitnih efekata za konkretna poluprovodnicka stakla visoke elektricne otpornosti. Izvrsena su detaljna ispitivanja frekventne zavisnosti dielektricnih parametara stakala sa bizmutom u intervalu 1 kHz-1 MHz na odgovarajuim temperaturama. Dobijeni rezultati tumaceni su u skladu sa Debye-evom teorijom molekulskih dipola i ukazali su na postojanje razlicitosti u tipu dipola koji odreuju mehanizam dielektricnog ponasanja ispitivanog stakla. Iz Cole-Cole dijagrama odreeno je vise disperzionih parametara koji blize opisuju pojavu dielektricne relaksacije u niskotemperaturskoj i visokotemperaturskoj oblasti. Prema Erying-ovoj teoriji hemijske brzine odreeni su jos i entalpija H i aktivaciona energija dipolne relaksacije F. Rezultati su ukazali i na postojanje distribucije vremena relaksacije dipola, kao i postojanje razlicitih izvora dipola u nisko- i visokotemperaturskom rezimu. Utvreno je da je polaronski mehanizam odgovoran za znacajno poveanje dielektricne konstante na visim temperaturama. Na sistemima sa bakrom u temperaturnom intervalu 300-420 K ispitivana je elektricna DC provodnost, kao i AC provodnost u frekventnom intervalu 102-106 Hz do temperature od 398 K. Pokazano je da poveanje udela bakra utice i na poveanje provodljivosti, kao i na smanjivanje aktivacione energije. Nastavljena su iznalazenja najpogodnijih metoda za proracun disperzije indeksa prelamanja tankih filmova. Utvrene su potrebne korekcije kod primene Ceremuhinovog metoda na jednoslojnim i viseslojnim amorfnim sistemima. Zapoceta su detaljna istrazivanja optickih karakteristika poluprovodnika dopiranih elementima iz grupe retkih zemalja..

"Linear and General Algebra Tools in Information Technology"

Predicted targets of research in the fifth year of the project fully implemented. New results in the field of applied linear algebra are obtained. They are related to the problem of localization of generalized characteristic roots, and the localization of characteristic roots that can be used to demonstrate the stability of dynamical systems. This problem is present, among other things, in creating wireless networks, optical networks, in control theory, and in the construction and providing appropriate convergence computer algorithms. The new results, obtained by the researchers on this project, made significant progress in these areas of application. In this part of the research project, cooperation with universities in Wuppertal (Germany), Valencia (Spain), Zaragoza (Spain), Poznan (Poland), Rostov (Russia) Ioannina (Greece) and Kent (Ohio, USA) is continued . The results of that cooperation are published in the form of scientific papers in international journals and presented at international conferences. In the area of general algebra /semigroup theory/ we investigated the question whether a finite involution semigroup is inherently nonfinitely based (INFB). Aside from a criterion implying that a finite involution semigroup is INFB, obtained in collaboration with K.Auinger and M.V.Volkov, we managed to describe broad classes of finite involution semigroups lacking this property. In the area of discrete mathematics, the games of Avoider-Enforcer type were analysed. A precise estimate of the smallest number of moves needed for Enforcer's win in games of non-planarity and non-bipartiteness is obtained References:

''Alati linearne i opste algebre u racunarstvu"

Predvieni ciljevi istrazivanja u petoj godini rada na projektu su u potpunosti realizovani. Dobijeni su novi rezultati iz oblasti primenjene linearne algebre, koji se odnose na problem lokalizacije generalizovanih karakteristicnih korena, kao i na lokalizaciju karakteristicnih korena koja se moze iskoristiti za dokazivanje stabilnosti dinamickih sistema. Ovaj problem prisutan je, izmeu ostalog, u kreiranju wireless mreza, optickih mreza, u kontrol teoriji, kao i u konstrukciji i obezbeivanju konvergencije odgovarajuih racunarskih algoritama. Novi rezultati koje su dobili istrazivaci na ovom projektu napravili su znacajan pomak u navedenim oblastima primene. U okviru ovog dela istrazivanja na projektu nastavljena je saradnja sa univerzitetima u Wuppertalu (Nemacka), Valenciji (Spanija), Zaragozi (Spanija), Poznanu (Poljska), Rostovu (Rusija), Ioannini (Grcka) i Kentu (Ohio, USA). Rezultati te saradnje publikovani su u vidu naucnih radova i saopstavani na meunarodnim konferencijama. U oblasti opste algebre /teorija polugrupa/ istrazivano je svojstvo nasledno beskonacne baze (INFB) za konacne involutivne polugrupe. Pored kriterijuma za egzistenciju ovog svojstva, dobijenog u saradnji sa K. Auingerom i M.V. Volkovom, opisane su siroke klase konacnih involutivnih polugrupa koje nemaju INFB. U oblasti diskretne matematike, analizirane su igre tipa Avojder-Enforser. Data je precizna procena najmanjeg broja poteza potrebnih Enforseru za pobedu u igrama neplanarnosti i nebipartitnosti.

"Lattice Methods and Applications"

The proposed plan of investigation is completely fulfilled and the related results are either published or accepted for publication or submitted to international journals. The investigation on lattice methods was conducted in two directions. Firstly, new results on rectangular islands were obtained, using lattice and combinatorial methods. It is proved that for every lattice valued relation there is a rectangular relation with the same islands. Further, new results about weighted tree automata are obtained using the cutworthy approach. Also, new results about lattice valued identities and algebras and also lattice valued ideals and filters are proved. The results are presented at international conferences and also published in eminent journals in the field. Concerning the second line of investigation, the concept of homomorphism-homogeneity of relational structures was treated. This concept was introduced by Peter Cameron and Jaroslav Nesetril as an interesting and natural generalization of the classical notion of homogeneity. The problem of classifying homomorphism-homogeneous structures is attracting more and more attention of the scientific audience, and up to now only some combinatorial results were published, mostly by the researchers affiliated to this project. In our recent results we managed not only to characterize, but also to enumerate some classes of homomorphism-homogeneous objects; we have also succeeded in providing a model-theoretic insight into the structure of countable homomorphism-homogeneous objects. Some of those results form a basis for the PhD dissertation of dr Maja Pech (defended on May 22nd, 2009; supervisor: dr Dragan Masulovi). References:

"Mrezne metode i primene"

Svi ciljevi istrazivanja u ovom periodu su ispunjeni. U vezi sa prvim pravcem istrazivanja dobijeni su novi rezultati u vezi sa rektangularnim ostrvima, u saradnji sa kolegama iz Segedina, a takodje i ocekivani rezultati u vezi sa tezinskim automatima u saradnji sa kolegama iz Drezdena. Pored toga, dobijen je i vei broj novih rezultata u vezi sa korisenjem rezidualnih mreza u rasplinutim skupovima i rasplinutim relacijama. Ovi rezultati su izlozeni na meunarodnim konferencijama gde su pobudili veliki interes. U vezi sa drugim pravcem istrazivanja i dalje je proucavana homomorfizamhomogenost. To je osobina relacionih struktura na koju su ukazali Piter Kameron i Jaroslav Nesetril kao na interesantno i prirodno uopstenje klasicnog pojma homogenosti. Problem utvrivanja da li data relaciona struktura poseduje osobinu homomorfizam-homogenosti ili ne je veoma aktuelan, a do sada je dobijeno svega nekoliko kombinatornih rezultata, i to uglavnom u radovima clanova ovog projekta. U radovima ciji autori su clanovi ovog projekta prvi put je ne samo okarakterisana, ve i potpuno enumerisana jedna klasa homomorfizam-homogenih struktura. Osim toga, prvi put je dat modelteoretski pristup razumevanju strukture homomorfizam-homogenih objekata. Istrazivanja na polju homomorfizam-homogenih objekata proizvoljnih kardinalnosti kao jedan od rezultata imaju i odbranjenu doktorsku disertaciju dr Maje Pech (mentor: dr Dragan Masulovi, datum odbrane: 22. maj 2009. godine)

"Mathematical Models in Information Technologies"

1. Mathematical models for Global Computing Systems. We have continued, in the field of clone theory, with the study of maximal hyperclones on a finite set. The work was inspired by results of Tarasov, in which he investigates maximal partial clones on a two-element set. We introduce a new operation in the set of extended hyperoperations and define a quasiclone as a composition closed set of extended hyperoperations containing all projections which is closed with respect to the new operation. Finally, we re-state the results of Tarasov in hyperclone framework. We have continued with investigation of the lambda Gentzen calculus, intuitionistic sequent term calculus, in two directions. We constructed two sub-calculi that enjoy the very important Church-Rosser property (aka the confluence). These calculi are obtained by modification of the syntax and the reduction rules, in order to implement particular computational strategies, namely "call-by-value" and "call-by-name". We proved that both new systems, with the same set of rules for assigning simple types, preserve the good properties of their predecessor - the strong normalization and the subject reduction property. We have been developing mathematical models for distributed system and decentralized peer-to-peer networks in which users have limited access to the data. A location (peer) is described with its data and processes. In order to obtain a system in which users have different access rights, we assign sets of roles and we use them to control data usage. The access rights of a role at a location can be changed (increased or decreased) only if policy of that location allows it. We propose a type system which ensures that the specified network policy is respected during computations and that a user can access and change only data in the range of its roles. 2. Mathematical models for digital image processing. Area coverage segmentation methods, resulting in object representations with fuzzy borders, are further studied and developed. Application of the proposed methods to medical (X-ray and CT) image registration is successfully performed and evaluated. New distance functions, to be used to measure distance between sets, are proposed and evaluated, with a particular interest in applications to image registration. Tests on real biomedical images confirm excellent performance of the proposed distances and related registration method. As an important step prior to segmentation, de-noising of images is explored as well, and methods based on total variation minimization are considered. An existing, well performing method for total variation minimization, is further improved by incorporating a new optimization approach, based on the SPG (Spectral Conjugate Gradient) algorithm. The proposed method outperforms the state of the art methods, while at the same time providing more flexibility in application. The method is successfully tested on the task of denoising SRµCT wood fiber images, used in automatized quality control of wood fibers, required in paper industry. References: 1. 2. 3. 4. 5. 6.

"Matematicki modeli u informacionim tehnologijama"

1. Matematicki modeli za globalno racunarstvo. U oblasti teorije klonova nastavljeno je sa proucavanjem maksimalnih hiperklonova na konacnom skupu. Date su karakterizacije tri klase maksimalnih hiperklonova koje su odreene Rosenbergovim relacijama. Uraena je uporedna analiza Tarasovih rezultata sa poznatim rezultatima o maksimalnim hiperklonovima na dvoelementnom skupu. U domenu razvoja formalnih metoda koje su osnova teorijskog racunarstva, istrazivanje lambda Gentzen racuna, intuicionistickog sekventnog racuna sa termima, je nastavljeno u dva smera. Konstruisana su dva podsistema osnovnog racuna koja zadovoljavaju osobinu konfluentnosti, cije odsustvo je predstavljalo najozbiljniji nedostatak lambda Gentzen racuna. Definisana su pravila redukcije i tipski sistem sa osnovnim tipovima za ovaj racun, i dokazane su osobine jake normalizacije i ocuvanja tipa prilikom redukcije. Nastavljen je rad na razvijanju matematickog modela za distribuirane sisteme i decentralizovane peer-to-peer mreze u kojima korisnici imaju ogranicena prava pristupa podacima. Jedna lokacija (peer) u nasem modelu je opisana podacima i procesima koji se na njoj nalaze. U skladu sa zahtevom da korisnici imaju razlicita prava pristupa podacima, procesima dodeljujemo uloge i na osnovu njih kontrolisemo upotrebu podataka. U domenu istazivanja relacija bisumulacija za procesne racune, radili smo na primeni Leifer-Milner RPO tehnike za dobijanje sistema oznacenih tranzicija iz sistema reakcija. Relacija bisimulacije koja odgovara ovako dobijenom sistemu oznacenih tranzicija je relacija kongruencije. Primenom optimizovanog oblika ove tehnike na pi-racun dobili smo konacan sistem oznacenih tranzicja i pokazali da je odgovarajua relacija bisimulacije sintakticka. 2. Matematicki modeli za racunarsku obradu slike. U daljem istrazivanju razvijane su metode segmentacije koje kao rezultat daju objekte sa fuzzy-rubom, u skladu sa prekrivenosu piksela. Nastavljen je rad na poboljsanju metoda za registraciju 2D i 3D digitalnih slika dobijenih X-zracima, gde se poboljsanje postize korisenjem fuzzy segmentovanih objekata. Predlozene su i detaljno evaluirane nove funkcije rastojanja izmeu skupova, koje se mogu primeniti u postupcima registracije slika.

"Spectroscopic and Thermodynamic Investigation of Complexes in Multicomponent Systems"

There is a growing interest of utilization of so-called alternative energy sources, such as solar radiation, wind, cooling water, exhaust gases, off-peak electric energy, etc. So far, the solar energy is mainly used in residential field (space heating and cooling, domestic water heating systems) and in agriculture (greenhouse heating), but there are also several pilot solar electric power plants. To achieve demands of alternative and renewable energy sources, solar energy should be stored and available at night and on cloudy days. For that reasons, all solar heating systems require a thermal energy storage device suitable for passive solar applications. Such "smart materials" can be easily incorportaed in building materials and their development is mostly oriented towards the area of latent heat storage in phase change material (PCM). Low temperature multicomponent systems containning inorganic salts or inorganic salt ­ organic solvent mixture suitable for thermal heat storage have been investigated. Calcium nitrate tetrahydrate or ammonium nitrate and their mixtures with some organic compounds (formamide, Nmethylformamide, dimethylsulfoxide) have high latent heat of fusion and have been considered as phase change materials (PCM) for thermal energy storage during our work. Electrical conductivity of liquid xCa(NO3)2·zH2O + (1­x)NH4NO3 mixtures was measured as a function of temperature over the whole composition range. A new assessment and experimental confirmation of quasi crystal theory of molten salts was made using electrical conductivity measurements as a suitable tool to show the difference between aqueous solutions and aqueous molten salt systems. Also, the influence of the electrolyte and water concentration on transport properties of the mixture was investigated. Also, DSC studies of calcium nitrate tetrahydrate and calcium nitrate tetrahydrate ­ ammonium nitrate mixtures were studied. From DSC thermograms, scanned in the temperature range 25 ­ 80 oC, the melting temperature, temperature of crystallisation and the latent heat of fusion were determined for pure compounds and their mixtures. Complex formation between cobalt(II) and halide and nitrate ions in different solvents were studied at several temperatures by spectrophotometric method. From an analysis of our experimental results, the number of absorbing species were determined by factor analysis. The overall stability constants of these complexes and the corresponding resolved species spectra were calculated. The influence of the solvent composition on complex formation were also studied.

''Spektroskopska i termodinamicka istrazivanja kompleksa u visekomponentim sistemima''

Proucavane su osobine pojedinih visefaznih sistema elektrolita i jonskih tecnosti koje se sastoje od dve neorganske soli ili jedne neorganske soli i organske komponente. Ovakve smese su posebno interesantne zbog svojih osobina poput visoke latentne toplote i niske tacke topljenja, sto omoguava njihovu primenu kao fazno-promenljivih materijala pogodnih za skladistenje energije. Stoga je od velike vaznosti bilo odreivanje njihovih fundamentalnih karakteristika i parametara. U tom cilju, ispitana je elektricna provodljivost smesa kalcijum-nitrat-tetrahidrat - amonijum-nitrat, formamid - amonijum-nitrat i dimetilsulfoksid - amonijum-nitrat. Razmotren je uticaj sastava smesa na njihovo konduktometrijsko ponasanje, sa posebnim osvrtom na eksperimentalnu potvrdu kvazikristalnog koncepta sistema koji ne sadrze, ili sadrze jako malu kolicinu vode (rastopa soli). Osim toga uraena su termicka merenja i ispitane termicke osobine pojedinih komponenti navedenih binarnih sistema, a u cilju mogunosti njihove primene kao fazno-promenljivih materijala. Kada se u ovakve sisteme doda neka susptanca koja podleze promeni boje sa promenom temperature (termohromni efekat), tada je mogua njihova primena i kao materijala za osencenje prostorija ili staklenika i njihovu zastitu od preteranog suncevog zagrevanja. Stoga je proucavano i kompleksiranje kobalta(II) sa halogenidnim jonima u gore navedenim smesama. Za reakcije nastajanja ovih kompleksa, odreene su odgovarajue konstante stabilnosti primenom nelinearne regresione analize i termodinamicki parametri (standardna entalpija i entropija nastajanja). Rezultati nasih istrazivanja prezentovani su na nekoliko meunarodnih kongresa, odrzano je jedno predavanje po pozivu (Molten Salt Discussion Group), dva rada su objavljena u meunarodnom casopisu kategorije M23, a dva u vodeim meunarodnim casopisima koeficijenta M21. Dr Slobodan Gadzuri ima objavljenu i monografiju stampanu u SAD i Velikoj Britaniji na engleskom jeziku. Osim toga, ucesnici projekta ucestvovali su na nekoliko meunarodnih kongresa i uspesno izlozili svoje najnovije rezultate.

"Determinig the Persistan Organic Pullutants in Abiotic and Biotic Matirx of Southern Backa"

Within the industrial area of the South Backa, surface water and sediment samples were collected and analysed on presence of residues of PAHs and PCBs. In surface water samples, naphthalene was detected in the concentration level range of 0.011-0.07 µg/l. Naphthalene, anthracene, fluoranthene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, indeno(1,2,3,c,d)pyrene and benzo(g,h,i,)perylene were detected in samples of sediment. Concentration levels of PCBs in water samples were below limit of detection, while PCBs in sediment were not detected. In the frame of the project task, air samples from the four sampling sites in the city of Novi Sad were collected and subjected to GC/MS analysis on content of PAHs. In addition, soil samples from the same four locations were collected and analysed. Using obtained experimental results, theoretical absorption model of atmospheric gas-particle distribution of the semi volatile organic compounds, as well as partitioning of POPs in the complex heterogeneous system air-soil, was tested on the territory of Novi Sad. Human milk in the earliest lactation was analyzed on the presence of DDT and their metabolites, isomers of HCH and PCBs. Comparing the results of human milk's contamination in South Backa region from 1982, the decreasing concentration trend for DDT and metabolites, HCH and PCBs could be noticed. The latest results indicate that, at the beginning of lactation, average daily intake of human milk is below limit value according to EU standard value for the pesticides in food for infants and kids. According to the research plan for 2009, concentration levels of compounds were monitored above the open tanks of the waste water treatment in Oil Refinery Novi Sad. Measurements of volatile organic compounds were conducted in the printing industry as well. Concentration levels of isopropyl alcohol, acetone and methyl ethyl ketone were detected as the result of use of these chemicals in the printing process, as the basic components included into the printing colour and the means for moistening. Detected concentration levels were within recommendations of international organizations. References:

"Odreivanje perzistentnih organskih polutanata u abiotskom i biotskom matriksu Juzne Backe"

Na podrucju industrijske zone Juzno Backog okruga odreen je sadrzaj perzistentnih organskih polutanata (PAH, PCB) u sedimentu i povrsinskoj vodi. U uzorcima vode sa svih lokaliteta, detektovan je naftalen u koncentracionom opsegu od 0,011-0,07 µg/l. U sedimentu ispitivanih lokaliteta detektovani su naftalen, antracen, fluoranten, benzo(b)fluoranten, benzo(k)fluoranten, benzo(a)piren, indeno(123-cd)piren i benzo(ghi)perilen. Koncentracioni nivoi PCB u uzorcima vode bili su ispod granice detekcije, dok u uzorcima sedimenta nisu detektovani. Istrazivanje sprovedeno u okviru Projekta obuhvatilo je odreivanje sadrzaja policiklicnih aromaticnih ugljovodonika u gasovitoj i suspendovanoj fazi ambijentalnog vazduha na cetiri merne tacke teritorije grada Novog Sada. Kao dodatni pokazatelj nivoa kontaminacije selektovanih mernih tacaka, uzorkovano je i zemljiste na definisanim lokalitetima. Rezultati eksperimentalnog odreivanja predstavljali su osnovu za procenu validnosti teorijskog KOA apsorpcionog modela raspodele poluisparljivih organskih jedinjenja izmeu gasovite i cesticne faze atmosfere, kao i raspodele polutanata u kompleksnom sistemu vazduh-zemljiste, teritorije grada. Humano mleko u najranijoj laktaciji analizirano je na sadrzaj DDT i metabolita, izomera HCH i PCB. Monitoring kontaminacije humanog mleka u Juznoj Backoj od 1982, ukazuje na trend pada za DDT i metabolite, heksahlorcikloheksan i izomere i PCB, znacajan za svaku dekadu u odnosu na prethodnu (u okviru 4 dekade praenja). Poslednji rezultati ukazuju da je na pocetku laktacije procenjeni dnevni unos novoroenog deteta znatno ispod gornje granice Evropske zajednice za pesticide u hrani namenjenoj odojcadi i maloj deci. U skladu sa istrazivackim planom za 2009 godinu nastavljeno je sa monitoringom koncentracionih nivoa BTEX jedinjenja iznad otrvorenih rezervoara postrojenja za obradu otpadnih voda Rafinerije nafte Novi Sad. Sprovedena su merenja koncentracionih nivoa lakoisparljivih organskih komponenti u stamparijama. Detektovano je prisustvo izopropil alkohola, acetona i metil-etil ketona, kao rezultat upotrebe pomenutih hemikalija u procesu stampe kao osnovnih komponenti koje ulaze u sastav stamparskih boja i sredstva za vlazenje. Detektovani koncentracioni nivoi su u okvirima preporuka meunarodnih organizacija.

''Variational Approaches to Some Non-Linear Vibration Problems''

The main aims of this project are related to the applications of the variational approaches to different mechanical systems for the sake of their quantitative studies. These applications include: conservative oscillators with a fractional-order restoring force and constant parameters (publications 1, 5, 7, 8 and 10 in point 1.2 above), oscillators with a fractional-order restoring force and time-varying parameters (publication 4), a uniform cantilever beam carrying a lumped mass (publication 3), a rotor (publication 6), as well as some considerations of the brachistichrone problem (publication 2) and the minimum plane path for movable end-points (publication 9). The quantitative analyses have been performed by developing new analytical methods based on the simultaneous and non-simultaneous variation, an optimal variational iteration method as well as on the combination of the Krylov-Bogoliubov method with Hamilton's variational principle. The brachistochrone problem and the minimum plane path problem have been considered by means of the non-simultaneous variation. The results obtained have been published in four journal papers (publications 1-4), presented at a national conference (publication 5) and two international conferences (publications 6 and 7). In addition, three journal papers have been submitted for review (publications 8-10). Current research activities are concerned with the qualitative and quantitative study of the oscillators with a non-polynomial restoring force and linear viscous damping. This study has been carried out in cooperation with the researchers from Timisoara, and is expected to be completed in due course. References:

''Varijacioni prilazi nekim problemima teorije nelinearnih oscilacija''

Osnovni ciljevi projekta se ticu primene varijacionih prilaza za kvantitativnu studiju razlicitih mehanickih problema. Njihova realizacija je ostvarena kroz primenu na: konzervativne oscilatore sa restitucionom silom necelog stepena i konstantnim parametrima (publikacije 1, 5, 7, 8 i 10 u tacki 1.2), oscilatore sa restitucionom silom necelog stepena i vremenski promenljivim parametrima (publikacija 4), problem grede sa koncentrisanom masom (publikacija 3), jedne klase rotora (publikacija 6), kao i na razmatranje problema brahistohrone (publikacija 2) i problema nesimultane varijacije i minimuma putanje za pokretne granice (publikacija 9). Kvantitavine analize su ostvarene kroz razvijanje novih analitickih metoda baziranih na simultanoj i nesimultanoj varijaciji, optimalnog varijacionog iterativnog metoda, te na bazi kombinacije KrilovBogoljubov metode i Hamiltonovog varijacionog principa sa nekomutativnim pravilom. Problem brahistohrone i minimuma putanje su razmatrani u svetlu nesimultane varijacije. Rezultati istrazivanja navedenih problema su publikovani u formi cetiri radova u casopisima sa SCI liste (publikacije 1-4), prezentovani na skupu od nacionalnog znacaja (publikacija 5) i na dva skupa od internacionalnog znacaja (publikacije 6 i 7). Osim toga, rezultati istrazivanja su dostavljeni na recenziju u casopise sa SCI liste u formi tri rada (publikacije 8-10). U toku je kvalitativna i kvantitativna studija oscilatora sa nepolinomijalnom restitucionom silom i viskoznom dispativnom silom, koja se radi u koautorstvu sa istrazivacima iz Temisvara, a cija se finalizacija ocekuje u narednih nekoliko meseci.

"Roma Children Integration into Education System of Serbia"

During previous research year, a field research in which 150 children were assessed was done (50 Roma chldren, 50 non-Roma children from economically deprived families and 50 non-Roma children from economically average families). School readiness was assessed with School Readiness Test (which is the result of the previous work in this project) and correlated with the school achievement (estimate by the teachers), economic status and demographic variables. Results achieved bring the data on necessary measures which could improve the school achievement of Roma children: necessity of pre-school program which could improve the incorporation of school skills and improve cognitive maturity, as well as necessity of wide action in order to change the negative attitude towards eduction among Romas. Additionally, results proved a validity of School Readiness Test (compared with parallel test TIP-1, as well as with the school achievement). At the end of the research year, a followup study on Roma children (now in the 2nd grade) started. Reference:

"Integracija romske dece u skolski sistem Srbije"

Osnovni projektni zadatak prethodne istrazivacke godine bila je provera valjanosti testova namenjenih proceni zrelosti za skolu u kontekstu realne uspesnosti u skoli, kao i istrazivanje faktora koji doprinose trajnoj nefikasnosti romske dece u skoli. Tokom prve polovine istrazivacke godine obavljeno je ispitivanje (na dodatnom uzorku) razlika u postignuu na testovima zrelosti za skolu meu romskom, ne-romskom i socijalno depriviranom ne-romskom populacijom, kao i ispitivanje povezanosti specificnih stavova i vrednosti sa uspesnou i uklopljenosu dece u skolski sistem. Posredni cilj je bio ispitivanje valjanosti Testa zrelosti za skolu u predikciji uspeha romske dece u prvom razredu. Dobijeni rezultati ukazali su na nesumnjivu valjanost Testa zrelosti za skolu (koji je rezultat rada na projektu u prethodnom istrazivackom periodu) kako u kontekstu kros-validacije (u poreenju sa testom TIP-1) tako i u kontekstu prediktivne validnosti (uspeha u skoli). Rezultati su objavljeni u casopisima i prikazani na naucnim skupovima. U drugoj polovini istrazivacke godine sprovedeno je ispitivanje uspesnosti u II razredu ucenika koji su testirani pre polaska u skolu, kao sastavni deo follow-up studije.

"Multiculturality of AP Vojvodina as a Factor of Regional Linking in Southeastern and Central Europe"

For this project year (2009) there was foreseen elaboration and theoretical explanation of the results of the pilot-questionnaire (which was realized during research activities in the previous year). Elaboration of the results means: a) statistical elaboration; b) quantitative and qualitative analysis of the data received by polling. On the basis of these proceedings it was approached to the explanation of received data (Sokolovska, Cobanovi, Niin, 2009; Cobanovi, Sokolovska, Nikoli-ori, 2009), as well as their wider theoretical problematization (Kokovi, 2009; Marinkovi, 2009a, Marinkovi, 2009b). It is important to mention that two of the articles are published on English in the journals which belongs to the M24 category (Sokolovska, Cobanovi, Niin, 2009; Cobanovi, Sokolovska, Nikoliori, 2009), and are also available online, which makes them accessible for interested experts worldwide. Also, the member of the research team dr. Valentina Sokolovska introduced some parts of the project results at two international conferences hold in Ljubljana and Segedin: 1. Cobanovi, K. i V. Sokolovska (2009). Changes in the Marital Structure of the Population of Vojvodina in Respect to their National-Ethnic and Confessional Affiliation. In: Lara Rusa and Hanez Star (ed.)

"Politicki mitovi na prostoru bivse Jugoslavije"

Osnovni cilj clanova istrazivackog tima bio je da se problem mitova epohe socijalizma osvetli iz perspektiva istorije, politicke sociologije, sociologije kulture i antropologije. Kao rezultat rada na projektu napisano je pet radova, ukupnog obima oko stotinu i pedeset stranica. Radovi clanova istrazivackog tima iz Srbije prevedeni su na engleski jezik. U radu ,,Politicki mitovi socijalizma od komunizma do boljsevizma" prof. dr Ljubisa Despotovi najpre na uopste nacin analizira mitotvoracku praksu socijalizma, da bi zatim presao na razmatranje mitologizacije i mistifikacije licne vlasti J.B. Tita. Posmatrajui mitove kao oblik kulturnog resursa, doc. dr Sran Sljuki (,,Mit o izabranosti: komunizam u Jugoslaviji") pise o mitu o ,,izabranosti" komunista, sa posebnim osvrtom na jugoslovenske komuniste. Prof. dr Darko Gavrilovi (,,Komunisticki mitovi: pravoslavna crkva u Sovjetskom Savezu i Jugoslaviji kao neprijatelj i prognanik komunizma") usredsreuje se na mit o neprijatelju u verzijama sovjetskih i jugoslovenskih komunista. U svom prilogu pod nazivom ,,Kult narodnih heroja i patriotska mitologija titoizma", prof. dr Vjekoslav Perica (Filozofski fakultet Rijeka, Hrvatska) analizira patriotske mitove jugoslovenske socijalisticke ere (1945-1990).

"Dialect of Novi Sad"

The analysis was carried out on the data gathered from 231 questionairres answered by adult citizens of Novi Sad (either born in Novi Sad or those who immigrated from the territories of South Backa or Severni Srem vernaculars; or from other dialectal regions), 40 school children from lower grades and 97 high school students; as well as the language of the media and a 15 hour corpus of spoken language. The pilot study was carried out on the sample of speakers from Petrovaradin (61 subjects). Research results: remarkably high degree of standard language features in the morphology of nouns and verbs (Milan Ajdzanovi), derivational models and in the derivation of ktetics (Gordana Strbac, Milan Ajdzanovi, Gordana Stasni, Dusanka Vujovi, Ivana Simovljevi), stable usage of infinitives in the formation of the Future I and functioning as a complemetizer (Jelena Vojnovi), stable standard language models of impersonal and passive sentence structure (Isidora Bjelakovi, Jelena Ajdzanovi), relatively stable models with causal and final adjuncts (Milivoj Alanovi), and in the complementization of adjectives (Natasa Kis). The results of the lexical research: significantly lower use of Germanisms and Hungarianisms (Milivoj Alanovi, Margita Snel, Edita Andri, Dusanka Zveki); passive knowledge of the terminology of the traditional culture ­ home and household, food and drinks, occupation, wedding ceremonies (Maja Stokin, Gordana Strbac, Zarko Bosnjakovi, Gordana Dragin). The study of pragmatic features: relatively stable models of addressing people regarding the age of the subjects (Mirjana Joci); poetic usage of vernaculars and dialects is exaggerated in the artistic works and special journalistic genres (Gordana Strbac, Jasmina Drazi, Ivana Lazi-Konjik, Vera Vasi), innovations in official and colloquial names of streets and city districts (Violeta Raki, Gordana Dragin). An overview of standard idioms (Isidora Bjelakovi, Jelena Vojnovi, Milena Zori); the future of Novi Sad spoken language (Ljiljana Suboti, Zarko Bosnjakovi, Vera Vasi, Maja Markovi, Ljiljana Petrovacki i Dejan Sredojevi).

''Role and Importance of Media Studies in Regional Cooperation''

Research within the project "Role and importance of media studies for interregional cooperation" focused on social position of the media. The primary areas of interest were specificities of media language and importance of creation of individual journalistic styles, media discourse analysis and effects of press reporting and interpreting major political events. Prominent topic was regional press reporting about multiculturalism, importance of media ethics in crises situations, the topic of the importance of library fond for media studies, and even the topic of active journalism and audience. Research under the last topic thematizes active audience approach with an aim to establish different levels of activity, from the one that follows from the semiotic understanding of communication to the activity in virtual communication. In the second part of that paper, the author discusses the implications of the audience activity for the journalism and journalism education. One of the main goals of the project was to establish the scope and manner of print media reporting about the topics related to national minorities in the countries of the region, and about multiculturalism. Research provided a comprehensive picture of the regional media context, and contemporary state of Vojvodinian media space. Topics are complementary in a best possible way ­ subtle analysis bordering media discourse theories, media genres analysis and their presence and impact on different forms of cultural cooperation are supplemented by concrete and qualitative analysis. Hence the project research made a connection between theoretical approaches and practical research of media effects. Following researchers took part in project realization: Janos Banjai, Mirjana D. Stefanovi, Dubravka Vali-Nedeljkovi, Dejan Pralica, Vladimir Barovi, Jelena Kleut, Violeta Raki i Kornelija Farago. The results of the project were published in the periodical "Zbornik radova", Faculty of Philosophy, 2010. Publication of the research in the periodical significantly contributes to the authority of the media studies within university disciplines. References:

"Mesto i znacaj medijskih studija za medjuregionalnu saradnju"

Istrazivanja na projektu Mesto i znacaj medijskih studija za meureginalnu saradnju su bila usmerena prema drustvenoj pozicioniranosti medija. U prvom redu prema saznanjima o specificnostima medijskog jezika i vaznostima izgradnje individualnog novinarskog stila, prema analizi medijskih diskursa, i prema ucincima stampe u pogledu njenog tumacenja znacajnih poitickih dogaaja. Meu istaknutim temama je bila i tema stampe iz regiona o multikulturalizmu kao i znacenje medijske etike u izostrenim situacijama, kao i tema znacaja biblioteckog fonda za studije medija, pa i znacaj aktivnog novinarstva i publike. Istrazivanje na tu poslednju temu problematizuje pristup aktivnoj publici sa ciljem da se odrede razliciti nivoi aktivnosti, od onog koji proistice iz semiotickog razumevanja komuniciranja do aktivnosti u virtuelnom komuniciranju. U drugom delu tog rada diskutuju se implikacije aktivnosti publike po novinarstvo i obrazovanje novinara. Jedan od osnovnih ciljeva projekta je bio da se istrazi u kojoj meri i na koji nacin odabrani stampani mediji iz pet zemalja regiona pisu o temama koje su u vezi sa problematikom nacionalnih manjina drzava regiona, ali i o multikulturalizmu Istrazivanja daju potpunu sliku o kontekstu medija u regionu, znaci u trenutno stanje celog medijskog prostora Vojvodine. Teme su komplementarne na najbolji mogui nacin. Uz suptilnije analize koje se granice sa teorijama medijskog diskursa, zanrova medija, kao i njihovog prisustva i uticaja na oblike kulturalne saradnje, vrsene su konkretne i kvalitativne analize. Dakle na projektnim istarzivanjima su zajedno teorijska promisljanja medija i prakticna izucavanja medijskih efekata. U realizaciji projekta su ucestvovali Janos Banjai, Mirjana D. Stefanovi, Dubravka Vali-Nedeljkovi, Dejan Pralica, Vladimir Barovi, Jelena Kleut, Violeta Raki i Kornelija Farago. Rezultati naucnoistrazivackog rada na projektu su objavljeni u Zborniku radova, Filozofski fakultet, Novi Sad, 2010. Istrazivanja objavljena u Zborniku radova u znacajnoj meri doprinose i autoritetu medijskih studija u sklopu univerzitetskih disciplina.

"Spiritual Resources of Vojvodina"

The question of man and world Kovac is a fiziokrat who accepts the world as it is. The world can be better, but the man should tend to better himself. Kovac's work belongs to the aestheticks of sameness and to the aesthetics of opposition. In the chapter the reader is exposed to Kovac's: 1. christianic moral imperatives: God's commandments, virtues, main sins, acts of mercy, evengelist councils; 2. glosary of biblical-theoretical questions: life, world. God, man, people, death, declaration, evangelism, evangelists, love, eart, language, ideas of stoicism, sin, shame, history, soul, time, work, children, sowing, reaping, church, bread, peace, consience; 3. philosophy and supramolism aesthetics of N.N. Fedorov, one of the versions of aesthetic sameness, implicitly present in Kovac's work. Fedorov functionalises the view of the world of the Russian people, and consumed with its spirit he speaks in their language, uses their emotional energy. This is not only the question of new history; it's a question of a new religion. In this religion whole mankind is a big family, connected by close family ties og common ancestors and unique destiniy, but, at the same time, it is a family about to fall apart, forgettings its cousins. To turn the hearts of the living towards the dead, the hearts of sons towards the fathers, is a big task directed by feelengs, a vow whose fulfillment by one mind determines the completion of the common task. The ancesstor cult is in the basis of Fedorov's religion. The religion of "common task" is introducing sence into human life and history. Know yourself in your fathers, and your fathers in yourself, and you will be the brotherhood of sons. That is the teaching of supramoralism, the philosophy of general syntesis of N.N.Fedor. Kovac takes over his two main conclusions. Our life is an aesthetic way of creation and: There is no art work that does not change life in some way. That is why art work is a project of new life.

Glosar biblijskoteoloskih pitanja; zivot, svet, Bog, covek, narod, smrt, zemlja, ljubav, objava, stid, istorija, crkva, hleb, smrt.3. imlicitno prisutna u Kovacevom delu filozofija i estetika supramoralizma N.N.Fedorova, jedne od verzija estetike istovetnosti. Fedorov funkcionalizuje pogled na svet prostog ruskog seljackog naroda, obuzet njegovim duhom progovara njegovim jezikom, koristi njegovu emocionalnu energiju.Nije rec samo o novoj istoriji, rec je o novoj veri. U toj veri citavo covecanstvo je velika porodica, povezana tesnim rodbinskim vezama zajednickih predaka i jedinstvenom sudbinom, ali, istovremeno, i porodica pred raspadom. Kult predaka je u osnovi religije Fedorova. Prof. dr Lajos Genc: U okviru teme Visejezicnost i multikulturalizam u Vojvodini proucavani su pedagoski aspekti ovih fenomena u voojvoanski uslovima. Osnovni rezultati saopsteni su na skupu Safe Children in Safe Communities (22-5. jun 2009, Novi sad) kao i u publikacijama pisanim za roditelje koji upisuju decu u prvi razred osnovne skole i treba da izaberu nastavni jezik. Takoe je izucavana problematika porodicnog vaspitanja u heterogenoj sredini i rezulati su publikovani u radu u prilogu. Prof. dr Jozef Salma proucavao je i zakljucke uoblicio temu Osnove nacela graansko pravne odgovornosti. Takoe, proucavao je osne prava zivotne sredine, kao i ugovorna i vanugovorna graansko pravna pitanja odgovornosti u delu slovenackog akadmeika Stojana Cigoja. Proucavao je i pravne aspekte razvoja porodicnog nasleivanja u Srbiji. Sve je to uobliceno u radovima koji su dati u prilogu.

"The Family as the Value in the Time of Socio-Political Transition"

Within this year, research team investigated following topics: development of family roles and relationships, functioning of families with a chronically ill child or child with psychiatric symptom, and functioning of foster families. Among other results, the first topic included research of correlates of mental health and life satisfaction of pregnant women. Also, we identified and described specific relations within families with preschool-aged child, that are related to conceptualization of parenting roles, parenting alliance, and that are observed as determinants of father involvement. The second and third topic aimed to identify and describe specific aspects of functioning and functionality of families with chronically ill child, or child with psychiatric symptom. Also, research team identified and described specific sources of stress related to foster parenting. This data might be helpful for the experts preparing future foster parents, and their families for the specific roles and relations they are about to experience. References:

"Porodica kao vrednost u drustvu u procesu tranzicije"

U ovoj projektnoj godini, tim projekta se bavio funkcionalnosu porodica u kontekstu razvoja porodicnih uloga i odnosa, specificnih porodicnih konstelacija (hraniteljske porodice) i u kontekstu zdravstvenih i/ili psihickih teskoa deteta. U prvoj oblasti (razvoj porodicnih uloga i relacija) prepoznati su cinioci mentalnog zdravlja i zadovoljstva zivotom trudnica. Cinioci se ticu kako relativno trajnih individualnih karakteristika, tako i karakteristika pripreme za materinstvo u smislu anksioznosti vezane za meterinsku ulogu, identifikacije sa trudnoom kao razvojnim procesom, samopouzdanjem i slicno. U daljem razvoju porodice, identifikovane su specificne relacije unutar porodice koje znacajno uticu na ukljucenost oceva, ali i na formiranje roditeljskog saveza i roditeljske uloge oca. Takoe, ispitivana je i funkcionalnost bracnih parova sa i bez dece, gde su uocene kategorije parova prema specificnim oblastima snaga i rizika. U drugoj i treoj oblasti identifikovane su i opisane specificnosti funkcionisanja porodica sa zdravstvenim i psihickim teskoama deteta, te oblici smanjene funkcionalnosti relacija unutar njih. Takoe, identifikovani su i opisani izvori stresa specificni za hraniteljsku ulogu, koji su od znacaja za pripremu hranitelja i pomo ovim porodicama u adaptaciji na uloge i relacije koji svojom strukturom imaju.

"Innovative Culture as a Factor in Creating and Developing Innovative Systems"

Research conducted using yuantitative methods of statistic analysis provides the ansver to the basic research question: is there an interconnection between elements of climate of the organisational creativity with measured level of management in the sample consisting of 244 economy organisations in APV. Theoretical framework of this research is based on scientifically and practically vrified models of management efficiency by M. Baldridge and on Situational Outlook Questionaire by Isaksen and Kaufman (1990) that assesses the climate of organisational creativity. The main hypothesis of this work has been confirmed ­ in reality, there is an interconnection between embryonic elements of organisational creativity climate and management efficiency in the observed selection of organisations in Vojvodina. By using several statistical tests, it has been confirmed that there is weak interconnection between organisational creativity climate and management efficiency in the observed of organisations in Vojvodina. Based on this evidence in contemporary Vojvodina, management of economy organisations, shaped according to traditional tailor model from early stages of capitalism, cannot be regarded as efficient. Only few organisations in Vojvodina that have from of modern economy organisation (creativity climate, learning organisations...) feature some advantages regarding organisational efficiency when compared to organisations that feature none of it. Althout to a marginal extent, management that fosters the climate of organisational creativity stands more efecient than majority of organisations featuring conflicts in human relations, dysfunctional debates and lack of willingness to except the risk of changes. Results of this research show members of management of economy organisations in Vojvodina are mostly unsatisfied by the actual organisational practice, and that they are quite often oriented towards adopton of modern approaches regarding improvement of efficiency of management in general; characteristics of manageres based on social experience fall into the system that determines their attitudes towards creativity. Thesse findings imply that better understanding of personal characteristics of members of management can serve as an important factor in establishing high level of management efficiency in organisations in Vojvodina.

"Inovaciona kultura kao faktor u formiranju i razvoju inovacionih sistema"

Istrazivanje koje smo sproveli tokom 2009 ­ 10. godine, primenom kvantitativnih metoda statisticke analize daje odgovor na osnovno istrazivacko pitanje: postoji li povezanost elemenata kreativne organizacione klime sa izmerenim nivoom efektivnosti menadzmenta na uzorku od 244 privredne organizacije u AP Vojvodini. Teorijski okvir ovog istrazivanja zasnovan je na naucno i prakticno verifikovanim modelima efektivnosti menadzmenta M. Baldridza i na upitniku situacionog pregleda Isaksena i Kaufmana iz 1990. koji meri kreativnu organizacionu klimu. Osnovna hipoteza istrazivanja je potvrena ­ da u stvarnosti postoji povezanost embrionalnih elemenata kreativne organizacione klime i efektivnosti menadzmenta u posmatranom skupu organizacija u AP Vojvodini. Primenom vise postupaka statistickih testova, potvreno je da postoji slaba povezanost kreativne organizacione klime i nivoa efektivnosti menadzmenta u analiziranom uzorku organizacija. Na osnovu ovog dokaza, u savremenim okolnostima u Vojvodini ne moze se smatrati efektivnim menadzment privrednih organizacija koje su oblikovane prema tradicionalnom tejloristickom modelu proisteklom iz ranih etapa razvoja kapitalizma. Kod malog broja ispitivanih organizacija, sa karakteristikama modernih privrednih organizacija (kreativna klima, elementi organizacije koja uci...) mogu se zapaziti prdnosti u pogledu organizacione efektivnosti u odnosu na organizacije bez takvih karakteristika. Iako u neznatnoj meri, menadzment koji neguje kreativnu organizacionu klimu je efektivniji od veine organizacija u kojima preovlauje klima konflikata u meuljudskim odnosima, nefunkcionalnih rasprava i sporenja kao i odsustva spremnosti da se prihvati rizik promena. Rezultati ovog istrazivanja pokazuju da je kod pripadnika menadzmenta privrednih organizacija u Vojvodini u znacajnoj meri prisutno nezadovoljstvo aktuelnom organizacionom praksom i da su stoga relativno cesto orijentisani na usvajanje savremenih pristupa unapreivanju efektivnosti menadzmenta, da je njihova sklonost uspostavljanju kreativne organizacone klime pozitivno korelirana sa nivoom efektivnosti menadzmenta u celini, kao i da posmatrane socijalnoiskustvene osobine pripadnika menadzmenta spadaju u sistem odrednica njihovih stavova prema negovanju klime kreativnosti, i najzad, pokazalo se da crte licnosti pripradnika menadzmenta imaju znacajan uticaj na formiranje stavova prema kreativnosti. Implikacija ovih nalaza je saznanje da poznavanje osobina licnosti pripadnika struktura menadzmenta moze predstavljati znacajan faktor za ostvarivanje visokog nivoa efektivnosti menadzmenta u privrednim organizacijama u AP Vojvodini.

"Design of the Revitalisation Programme for Depopulated Border Regions in Banat"

The main aim of the project "Design of the revitalisation programme for depopulated border regions in Banat" is a detailed analysis of border municipalities in Banat: Novi Knezevac, Coka, Kikinda, Nova Crnja, Zitiste, Secanj, Plandiste, Vrsac and Bela Crkva in order to define the present condition and find solutions for depopulation decrease. The content of the project is divided into several parts. The introductory part refers to the position and geographical features of border municipalities in Banat. The next part is a detailed demographic analysis which comprises changes in population number, population structure (gender, age, ethnic, religious, economic and educational), migrations, households and employment. The last part incorporates several local proposal programmes: for emigration prevention, primarily younger population groups, for unemployment reduction in municipalities, with joint programmes for tourism development and complementary services. Within this proposal regarding revitalisation of depopulated border regions in Banat, several subproposals have been introduced for local, municipal, county, regional and state's level. Furthermoer, SWOT analysis has been conducted to highlight strengths and utilisation of potentials, to identify weaknesses and handling the problems and to define opportunities and threats as well as to establish the procedures for population increase and emigration decrease. The final goal of the project is the identification of high priority through several points: Design of local programmes for family planning including precalculated number of children necessary to ensure long term generation replacement , prevention of emigration, primarily the young population, employment expectancy by the year 2013 with regard to business and occupation, improvements in local and intercity traffic to enable daily instead of permanent migrations, unemployment reduction in municipalities. Successful field research and detailed analysis of specialist and scientific literature in demographic disciplines have resulted in numerous scientific papers and one published monograph. Within the project, there was one plenary talk on the topic "Changes in the Population Size of the Border Municipalities in Banat", held in Zrenjanin on March 13 2010. The lecture was attended by geography teachers, members of the school management and municipality representatives. Reference:

"Izrada programa za revitalilzaciju depopulacionih pogranicnih podrucja Banata"

U toku proteklog istrazivackog perioda na projektu pod nazivom ''Izrada programa za revitalizaciju depopulacionih pogranicnih podrucja Banata'' data je detaljna analiza pogranicnih opstina Banata: Novi Knezevac, Coka, Kikinda, Nova Crnja, Zitiste, Secanj, Plandiste, Vrsac i Bela Crkva kako bi se definisalo trenutno stanje u ovim opstinama i pronasla mogua resenja za smanjenje depopulacije. Sadrzaj prijekta sastoji se iz nekoliko celina. Uvodni deo odnosi se na polozaj i geografske karakteristike pogranicnih opstina Banata. Sledeu celinu cini detaljna demografska analiza koja obuhvata promene broja stanovnika, strukture stanovnistva (polna, starosna i etnicka struktura, struktura prema veroispovesti, ekonomska struktura i obrazovna struktura stanovnistva), migraciona kretanja, domainstva i zaposlenost. Poslednji deo odnosi se na izradu lokalnih programa za zaustavljanje odseljavanja, pre svega mlaih kategorija stanovnistva, na smanjenje broja nezaposlenih lica u opstinama, a sve to kroz programe razvoja turizma i komplementarnih delatnosti. U okviru predloga mera za revitalizaciju depopulacionih pogranicnih podrucja Banata dati su predlozi koje treba sprovesti na lokalnom nivou, na nivou opstina, na nivou okruga, na regionalnom nivou i na nivou drzave. Takoe uraena je i SWOT analiza gde su istaknute prednosti, odnosno jake tacke (strengths), kao i mogunosti iskorisenja tih potencijala, zatim slabosti, odnosno slabe tacke (weaknesses) i mogunosti reakcije na date probleme, takoe definisane su i mogunosti, odnosno sanse (opportunities) kao i pretnje (threats) i utvrene su preporucive reakcije kako bi se poveao broj stanovnika i smanjilo odseljavanje. Krajnji cilj projekta je i odreivanje prioriteta koji se ogledaju u izrada lokalnih programa za planiranje porodice u kojima e se prethodno izracunati potreban broj dece za obezbeivanje dugorocne zamene generacija, zaustavljanje odseljavanja, pre svega mlaih kategorija stanovnistva, izrada projekcije potrebnih kadrova do 2013. po delatnostima i zanimanjima, pospesivanje lokalnog i meugradskog saobraaja, kako bi se umesto stalnih omoguile dnevne migracije i smanjenje broja nezaposlenih lica u opstini. Uspesna terenska istrazivanja i detaljna analiza strucne i naucne literature iz demografskih disciplina rezultirale su mnogobrojnim radovima i jednom objavljenom monografijom. U okviru projekta organizovano je i jedno plenarno izlaganje na temu "Promene broja stanovnika u pogranicnim opstinama Banata", koje je odrzano u Zrenjaninu 13.03.2010 godine. Predavanju su prisustvovali profesori geografije, clanov skolske uprave i predstavnici opstina.

"Regional Linguistic, Literary and Cultural Vectors in Multicultural Discourse: Slovak Model"

This project studies language, literature and culture of the Slovak ethnic minority in Vojvodina, Hungary and Romania with emphasis on the Slovak paradigm in Vojvodina. Research of the literature focuses on developing, typological and genre impressions and the situation in the 2nd half of the 20th century, especially on the newest literary events: aspects of narrative discourse in minority slovak literature in Vojvodina, Hungary and Romania (Michal Harpá), popular and elite dynamics in contemporary slovak literature (Adam Svetlík), bibliography of Juraj Tusjak´s translations (Jozef Valihora), the beginings of slovak children´s prose in Vojvodina (Jarmila Hodolic), permeations and parallels between the prose of Víazoslav Hronec and Serbian prose from the late 60's, 70's and 80's (Marína Simáková Speváková). The project also studies the linguistic culture in postmodern situation (Miroslav Dudok), consequences of corrections in the rhythmic law to word formation and change (Michal Týr) and the use of phraseologisms in a bilingual setting (example of Vojvodinian Slovaks) (Zuzana Týrová). Project researchers demonstrate the lingual, literary and cultural dynamics of the Slovak minority`s culture and its coexistance and cooperation with other ethnic paradigmas in the multicultural space of Vojvodina (overwhelming the territory of Vojvodina).

"Entrepreneurial Aspirations of Students in Vojvodina"

Factors which influence forming of entrepreneurial inclinations among high school students are explored in this study. Structural model was used in research including the following variables: education in entrepreneurship, school profile, school results, gender, family background, motivation, and observed obstacles in social environment. Empirical study through questionnaire is done at the sample of 775 last year students of general high schools and vocational (professional) schools in six cities of Vojvodina. Reserach results show that students in most cases think that they get partial knowledge in the field of entrepreneurship through teaching process. Almost half of them see teachers' engagement in the porcess od entrepreneurial culture development as partial. About forty per cent see overall school environment as partly stimulating for development of innovative abilities. One forth of tested students only estimate that they will have enough knowledge and abilities to start their own business after graduating high school. Almost 45 per cent of tested students showed inclination towards business start up. There is statistically significant relation between gender, father profession, scholl results on one side and entrepreneurial inclinations. Over half students evaluate social circumstances as negative for entrepreneurship and 9 per cent only as good, what is a signal that social circumstances are disrupting factor for young people to enter entrepreneurship. Above mentioned results confirm suitability of this reserach as a valid basis for widening and enriching education in entrepreneurship in high school curricula and through other school activities. Key words: students, entrepreneurship, education, business start-up, social environmnet. References:

"Preduzetnicke sklonosti studenata i odnos prema budunosti "

U 2009. godini istrazivane su determinante oblikovanja preduzetnickih sklonosti meu ucenicima srednjih skola u Vojvodini. U istrazivanju je primenjen strukturalni model (Rodrigues, Raposo at all., 2007; Turker, Sonmez Selcuk, 2008) koji ukljucuje sledee varijable: preduzetnicko obrazovanje, tip skole, skolski uspeh, rod, porodicno poreklo, motivaciju i opazene prepreke u drustvenom okruzenju. Empirijsko istrazivanje putem upitnika sprovedeno je na uzorku od 775 ucenika zavrsnih razreda srednjih strucnih skola i gimnazija u sest gradova u Vojvodini: Novom Sadu, Rumi, Iniji, Subotici, Vrscu i Zrenjanin. Nalazi istrazivanja ukazuju da je proces formiranja preduzetnicke kulture poceo da se odvija i u srednjim skolama. U malom broju skola preduzetnistvo je uvedeno u skolske kurikulume kao poseban predmet, dok u nekima postoje prakticni programi za ohrabrivanje preduzetnickih aspiracija srednjoskolaca (ucenicka preduzea, projekti i radionice). Meutim, samo petina ispitanih ucenika ocenila je da kroz nastavne predmete dobija znacajan fond znanja iz preduzetnistva, nesto preko 40% parcijalna, dok vise od treine smatra da su takva znanja izostala. Gotovo polovina ocenjuje angazman nastavnika u razvijanju preduzetnicke kulture kao delimican, petina konstatuje da on postoji, a nesto ispod treine da ga nema. Priblizno 9% percipira opstu atmosferu u skoli kao vrlo podsticajnu, 41% kao delimicno podsticajnu, a treina da nije podsticajna za razvijanje inovativnosti. Shodno ovim nalazima, samo cetvrtina ispitanih ucenika smatra da ima dovoljno znanja i sposobnosti da nakon zavrsetka srednje skole osnuje vlastiti biznis. Priblizno 45 procenata anketiranih ucenika ispoljilo je preduzetnicke sklonosti. Utvrena je statisticki znacajna povezanost izmeu obelezja rod, zanimanje oca, skolski uspeh i preduzetnicke sklonosti. Nesto vise od polovime mladia (51,78%) zainteresovano je za otvaranje privatnog biznisa, a nesto manje od treine devojaka (32,97%). Ucenici iz porodica preduzetnika najcese ispoljavaju sklonost ka zapocinjanju vlastitih biznisa (62,66%), a zatim deca rukovodilaca i strucnjaka sa visom skolom (blizu polovina). Vise od polovine ucenika sa prosecnim uspehom izmeu 2,0 i 3,0 je orijentisano ka otvaranju privatnih biznisa, a samo jedna treina onih sa prosecnom ocenom izmeu 4,1 i 5,0. Preko polovine ispitanika ocenilo je drustvene okolnosti u Srbiji danas kao nepovoljne za preduzetnistvo, a samo 9,0% kao povoljne. Treina smatra da su preduzetnici, koje poznaju, uspeli na poluleglne ili neleglane nacine. To ukazuje da su navedene okolnosti ometajui faktori za ulazak mladih u preduzetnistvo. Izneti rezultati potvruju celishodnost ovog istrazivanja kao validne osnove za prosirenje i obogaivanje preduzetnickog obrazovanja u kurikulumima srednjih skola.

''Possibility of Cultural Tourism Development in Vojvodina''

The development of tourism in Vojvodina can be based on the rich and diverse cultural heritage. For the creation and shaping of the culture tourism offer, it is necessary for the management of Vojvodina to define tourism as an important part of the total development of the Province, to encourage the development of resources management, to investigate and define culture as a resource for the creation of the tourism attractiveness of Vojvodina. It is very difficult to create an image of Vojvodina as a tourist destination. However, the development of culture tourism in Vojvodina would contribute to the faster development of the identity and the image of Vojvodina as a tourist destination. This is why it is necessary for culture tourism of Vojvodina to be included in the development planning on all levels, more precisely from the networking of The Provincial Secretariat for Culture and The Provincial Secretariat for Economy, to the networking of urban communities in the Province. In Vojvodina, culture tourism has not been included in the tourism development plans yet, and there still exists the misinterpretation of culture as an element of mass tourism product. The development of culture tourism in Vojvodina would ensure the protection of culture traditions as well as enhancement of the quality of living in rural and urban settings. The achieved economic benefits from culture tourism would be used for the conservation and preservation of cultural heritage. The development of cultural tourism in Vojvodina depends on the development of resources management in which culture and cultural heritage are investigated and defined as tourism resources.

''Mogunosti razvoja kulturnog turizma u Vojvodini''

Razvoj turizma u Vojvodini, moze da se zasniva na bogatom i raznovrsnom kulturnom nasleu. Za stvaranje i oblikovanje ponude kulturnog turizma, potrebno je menadzmentu Vojvodine odrediti turizam, kao vazan deo celokupnog razvoja pokrajine, podsticati razvoj resursnog menadzmenta, istraziti i odrediti kulturu, kao resurs za stvaranje turisticke privlacnosti Vojvodine. Veoma je tesko stvoriti imidz Vojvodine, kao turisticke destinacije. Meutim, razvoj kulturnog turizma u Vojvodini, doprineo bi brzem razvoju identiteta i imidza Vojvodine, kao turisticke destinacije. Zato je neophodno kulturni turizam Vojvodine ukljuciti u razvojne planove na svim nivoima, tacnije od povezivanja Pokrajinskih sekretarijata za kulturu i privredu, do povezivanja gradskih naselja u Pokrajini. U Vojvodini kulturni turizam jos nije usao u planove razvoja turizma i jos uvek postoji pogresan stav, da je kultura element proizvoda masovnog turizma. Razvoj kulturnog turizma u Vojvodini, omoguio bi zastitu kulturnih tradicija, kao i obogaivanje kvaliteta zivota u ruralnim i urbanim sredinama. Ostvareni ekonomski efekti od kulturnog turizma, koristili bi se za obnovu i zastitu kulturnih dobara. Razvoj kulturnog turizma u Vojvodini, zavisi od razvoja resursnog menadzmenta, u kojem se kultura i kulturna dobra istrazuju i odreuju, kao turisticki resursi.

''Kabinet malog crteza sa Kolekcijom crteza najboljih studenata i Kolekcijom crteza svih profesora i saradnika Akademije umetnosti''

Umetnicka praksa u poslednjim decenijama prepoznaje neminovnost koja se razvija kroz saradnju umetnosti i nauke. Od Disana do savremene umetnicke prakse, sprega nauke i umetnosti je neraskidiva kako na teorijskom tako i na prakticnom planu. Vizuelna komunikacija preko novih elektronskih medija dominira u sferi brzo prenosivih komunikacija i postaje umrezeni sistem uz pomo koga se informacija prenosi brzo neumoljivo i postaje globalni proces. Vizuelna komunikacija temelji se na crtezu kao osnovi za sve dalje vidove likovnih izrazavanja. Kroz crteze studenata Akademije umetnosti u Novom Sadu, koji se selektuju i teoretski obrauju jasno se vidi put koji studenti prelaze da bi ovladali elementima i principima crtanja i prosirili opservaciju, izgradili apstrahovan nacin misljenja licnom invencijom i otvorili put ka novim nacinima izrazavanja kroz sredstva novih likovnih, vizuelnih komunikacija. Obradu recentnih studentskih crteza sa teorijsko prakticnog aspekta izvrsili su clanovi projektnog tima. Obrada je konstantna, radi se na zavrsetku svakog semestra, te ima tendenciju stalnog rasta, i kao takva pruza velike mogunosti komparacija i edukacija. Clanovi projektnog tima cine: Jelena Trpkovi, vanred. prof . -rukovodilac projekta, Ljubomir Vucini, docent, Milos Vujanovi, docent, Olivera Mari - Nedi, docent i Biljana Jevti, asistent. Kabinet malog crteza, do sada, pored redovnih studentskih izlozbi na Akademiji, realizovao je izlozbu na Fakultetu likovnih umetnosti u Beogradu, u Kulturnom centru Novog Sada u Noi muzeja. Kabinet je realizovao CD izdanje kabineta koje sadrzi fotodokumentaciju, arhivski broj i strukturalno poetsku analizu svih radova. CD izdanje arhivirae se u Muzeju savramene umetnosti Vojvodine, Muzeju savremene umetnosti u Beogradu, Akademijama i fakultetima umetnosti, univerzitetskim bibliotekama, Akademijama umetnosti u Becu i Solunu i Francuskom kulturnom centru sa kojima imamo ostvarenu saradnju. Bie ponuena i ostalim kulturnim centrima i institucijama. U toku ove godine, kabinet malog crteza, prosirio je svoje kolekcije. Pored kolekcije studentskih crteza, nastala je kolekcija crteza svih nastavnika i saradnika koji su radili i rade na Akademiji umetnosti u Novom Sadu , kao i poklon kolekcija, sacinjena od umetnika van Akademije i Novog Sada koji zele da njihovi radovi budu deo, ovog, sada ve ekskluzivog Kabineta. Pored nesumljivog kulturnog blaga Novog Sada i Vojvodine, ova kolekcija analizira sociokulturoloske aspekte na osnovu individualnih poetika prikupljenih radova i prikazuje kopatibilnost sa savremenim pristupima umetnicke prakse kod nas i u svetu.

"The Interdependece of Economic Efficiency and Working and Living Enviroment Protection in Vojvodina Province"

The sum of individual values and inclinations, based on the qualified majority, directs and forms (through their legitimate representatives) the frameworks and aims of a community's policy (state, region, local self-government) or an organization (enterprise, company, and corporation). In this way, therefore, generating and establishing the majority of the same valuable matrices, the same or similar awareness on any phenomenon, aim or sense, it is possible to exert influence or pressure to change behavior and found different valuable orientations and systematic shaping the rules of behavior and their organized groups and communities. Education and information have the key role in these processes. The education system (and upbringing, too) is the key lever in forming and defining ecological awareness and actions based on it with a view of solving the set (or one at least) of problems relating to the living environment. Starting from the fact that ecological awareness includes ecological knowledge, ecological attitudes, ecological values and ecological behavior, we have researched personal attitudes of the employed about the ecological awareness in organizations (enterprises) in Vojvodina, the most developed region in Serbia, and we have found the interesting data presented in the project.

"Regional Aspects of the European Prosperity State with a View of Vojvodina"

In the current phase of research, it is tried to identify the degree in which the different social protection programs are successful in reducing poverty and how these solutions and experiences can be applied in Vojvodina. In order to do that, using the econometric methods (corrected ordinary least squares and panel regression) it is investigate the extent to which poverty rate is driven by economic, institutional and political variables in the EU-15 countries. The results suggest that employment, especially women employment, is the key factor for reducing poverty in the EU-15. When level of employment of poverty risk groups is high and levels of unemployment is low, more people contribute to the welfare state and the less draw on it, making any given level of redistribution more effective. Hence, the main task of social policy should be the promotion of employment programs. There are different ways for achieving the high employment rate of poverty risk groups. In recent years, the decentralisation of employment policy becomes a central issue. Bringing decision making closer to where problems are, decentralisation facilitates coordination of economic development strategies with labour market policies, adapting them to the regional and local needs and conditions. The final results are the better outcomes in terms of employment, social cohesion and sustainable development. Currently, decentralisation of social policy is one of the central issues for labour market policy in the EU-15. Therefore, the adaption of labour market policies, in the terms of greater decentralisation and enhancing the rule of regional and local authorities, implicitly becomes the one of crucial conditions not only for resolving the social problems but also for accelerating the European integration process of Serbia.

"Regionalni aspekti evropske drzave blagostanja s osvrtom na Vojvodinu"

U okviru tekue faze istrazivanja, cilj je bio da se utvrdi u kojoj meri su razliciti programi socijalne zasite u zemljama EU-15 dali pozitivne rezultate u suzbijanju siromastva i kako se ta resenja i iskustva mogu primeniti u Vojvodini. Da bi se to utvrdilo, primenom odgovarajuih ekonometrijskih metoda (korigovanih obicnih najmanjih kvadrata i panel regresije), istrazen je uticaj veeg broja ekonomskih, institucionalnih i politickih varijabli na stopu siromastva u zemljama EU-15. Dobijeni rezultati ukazuju da je zaposlenost, posebno zaposlenost zena, kljucni faktor smanjenja siromastva u EU-15. Uz visoku stopu zaposlenosti i nisku stopu nezaposlenosti socijalno rizicnih grupa, vise pojedinaca doprinosi nego sto zavisi od socijalne politike, cinei svaki sistem redistribucije znatno efikasnijim. Otuda, prioritetan zadatak socijalne politike bi trebalo da bude promovisanje programa usmerenih ka jacanju zaposlenosti. Razliciti su nacini za ostvarivanje viske stope zaposlenosti socijalno rizicnih grupa. Poslednjih godina, sve vise se istice znacaj decentralizacije politike zaposljavanja. Spustanjem procesa donosenja odluka do nivoa gde se problemi nalaze, decentralizacija snazno doprinosi koordinaciji i prilagoavanju strategija ekonomskog razvoja i politika trzista rada regionalnim i lokalnim potrebama i uslovima. Konacan ishod su bolji rezultati u pogledu stope zaposlenosti, socijalne kohezije i odrzivog razvoja. Decentralizacija politike zaposljavanja, danas, predstavlja jedno od centralnih pitanja trzista rada u zemljama EU-15. Otuda, prilagoavanje politike trzista rada, u smislu vee decentralizacije i jacanja uloge regionalnih i lokalnih vlasti, implicitno se namee kao jedan od kljucnih uslova ne samo u resavanju socijalnih problema ve i u procesu evropskih integracija Srbije.

''Industrial Policy and the Possibilities for Reindustrialization of Vojvodina''

According to the program of the research, the problem of the determining the strategy for reindustrialization of Vojvodina is being processed on three different levels. On the first level, the analysis on national frame of reindustrialisation was conducted in the function of development of export-oriented producing structures. Second, the problem of development of the agro-industrial complex in Vojvodina and the national energy system as basis for realization of regional strategy for reindustrialization was processed. The emphasis in the research of the factors of development of the agro-industrial complex was on identification of measures and mechanisms for its transformation in to export-oriented sector on the principles of self-reproduction and private initiative. The basis of the research of energy complex was on determining the principles of its privatization and liberalization in the function of creating good environment for private investments. On the third level, the research connected to the problem of development and functioning of basic producing-organization models in the industry of Vojvodina. The key finding was that the socialistic industrialization of Vojvodina in the period 1947-1990 had been realized by the model of industrial districts (sub regions). Until the end of that period, 7 industrial districts (Novi Sad, Subotica, Pancevo, Zrenjanin, Sombor, Sremska Mitrovica, and Vrbas) were formed with 27 sub regional or regional producing systems that had a structure of clusters that were mainly based on natural resources and/or investments. With the restorations of capitalism that structure has disappeared, because the industrial districts had lost their development functions, while the structure of regional and sub regional clusters was transformed (except NAFTAGAS as the part of NIS). In this context, the conducted research points out that the reindustrialization of Vojvodina should be realized by: (1) rehabilitation of industrial districts by developing at least one export-oriented macro-cluster, by using the inherited resources and private initiative, (2) developing at least one (authentic regional) pole of generic growth (in Novi Sad), and (3) more efficient use of synergetic effects of the overflow technologies and business from pole of generic growth from Belgrade in the regional industrial districts near the border (Pancevo, and Sremska Mitrovica).

"Industrijska politika i mogunost reindustrijalizacije Vojvodine"

Saglasno programu istrazivanja, problem odreivanja strategije reindustrijalizacije Vojvodine je sagledan u tri ravni. U prvoj ravni, izvrsena je analiza nacionalnog okvira za reindustrijalizaciju sa naglaskom na odreivanju novog koncepta makroekonomske politike u funkciji razvoja izvozno orijentisane proizvodne strukture. U drugoj ravni, obraena je problematika razvoja agro-industrijskog kompleksa Vojvodine i nacionalnog energetskog sistema kao materijalne osnove za realizaciju regionalne strategije reindustrijalizacije. Naglasak u istrazivanju faktora razvoja agro-industrijskog kompleksa je bilo na identifikaciji mera i mehanizama za njegovu transformaciju u izvozno orijentisani sektor na principu samoreprodukcije i privatne inicijative. Teziste istrazivanja u energetici je bilo na utvrivanju principa na kojima bi trebalo izvsiti njegovu privatizaciju i liberalizaciju u funkciji ostvarivanja visoke infrastrukturne udobnosti za privatno investiranje. U treoj ravni, realizovana su istrazivanja vezana za problematiku razvoja i funkcionisanja osnovnih proizvodnoorganizacionih modela u industriji Vojvodini. Kljucni nalaz je da je socijalisticka industrijalizacija Vojvodine u periodu od 1947. do 1990. realizovana po modelu industrijskih okruga (subregiona). Do kraja posmatranog perioda, formirano je 7 industrijskih okruga (Novi Sad, Subotica, Pancevo, Zrenjanin, Sombor, Sremska Mitrovica i Vrbas) sa 27 subregionalna ili regionalna proizvodna sistema koji su imali strukturu klastera, uglavnom, voenih prirodnim resursima i/ili investicijama. Restauracijom kapitalizma ova struktura je nestala, jer su svi industrijski okruzi izgubili svoje razvojne funkcije, dok su strukture regionalnih i subregionalnih klastera (sem NAFTAGAS-a u okviru NIS-a) razgraene. U ovom kontekstu, izvedeno istrazivanje ukazuje da bi reindustrijalizaciju Vojvodine trebalo izvesti: (1) rehabilitacijom industrijskih okruga razvojem bar jednog izvozno-orijentisanog makro-klastera, pre svega korisenjem onoga sto je ostalo od nasleenih resursa na osnovu privatne inicijative, (2) razvojem bar jednog (autenticnog regionalnog) pola generickog rasta (u Novom Sadu) i (3) efikasnijim korisenjem sinergetskih efekata prelivanja tehnologija i poslova iz pola generickog rasta u Beogradu na rubne regionalne industrijske okruge (Pancevo i Sremsku Mitrovicu).

''Competitive Advantages of Intelligent Data Analysis Methods in Strengthening the Sector of Small and Medium Sized Enterprises''

In the second year of the project research, due to the poor quality of acquired data and additional inconsistencies revealed during the intelligent data analysis (described in more detail in [6] and [7]), we have focused on specific, particular aspects of data subsets analysis, which are of greater value, thanks to a lover level of "noise" in such data (described in [1]). Furthermore, with the aim of data quality improvement, we made some consultations with relevant institutions (for e.g. the Regional Chamber of Commerce from Sombor), in order to acquire the missing data. Following the timeconsuming efforts of editing, transforming and loading the data, the previously established behavioral patterns, similarities and relations in SMEs data were verified. We also searched for better results by means of different analysis tools, as described in [2]. Besides diversified software tools, we have utilized different data mining algorithms for clustering. The justification of such a combined approach is given in [3] and [4], and the results are summarized in [5]. In this year of research, we started the development of Web based expert system (ES) for SMEs creditworthiness assessment, in EXSYS Corvid development tool. The domain knowledge acquisition was conducted through interviews with mr Miodrag Sljuki, B.Sc of Ecc. The conceptual model of ES has been developed and a knowledge base designed. In respect to the limitations of the development tool, the implementation has followed the modular architecture, comprising of separate ESs for assessment of business efficiency, financial standing, profitability, solvency and leverage, and the structure of incomes and expenditures.

"Komparativna prednost inteligentnih metoda analize podataka u jacanju sektora malih i srednjih preduzea"

U drugoj godini istrazivanja na projektu, zbog slabog kvaliteta obuhvaenih podataka i dodatnih nekonzistentnosti uocenih tokom sprovedenih analiza podataka inteligentim metodama (opisano u rezultatima [6] i [7]), smo se fokusirali na pojedinacne, specificne aspekte analize nad podskupovima podataka, koji su imali veu upotrebnu vrednost zahvaljujui manjem stepenu ,,sumova" u podacima (vidi [1]). Takoe smo u cilju poboljsanja kvalilteta podataka obavili razgovore sa relevantnim institucijama, kao npr. Regionalnom privrednom komorom Sombor, radi obezbeivanja nedostajuih podataka. Nakon zahvata editovanja, transformacije i objedinjavanja, ranije otkrivene sheme ponasanja, slicnosti, kao i uzrocno-posledicne veze u podacima o MSP su se potvrdile. Takoe smo pokusali dobiti bolje rezultate primenom razlicitih alata namenjenih rudarenju podataka, o cemu govori rezultat [2]. Pored razlicitih alata, rudarenje podataka smo sprovodili razlicitim tehnikama klasterovanja. O opravdanosti ovakvog kombinovanog pristupa se govori u rezultatima [3] i [4]. Nalazi do kojih smo dosli kombinovanim pristupom data mininga su sumirani u [5]. Tokom ove god. istrazivanja, zapoceli smo izgradnju Web baziranog ekspertnog sistema (ES) za procenu boniteta preduzea, u alatu EXSYS Corvid. Obavljena je akvizicija domenskog znanja putem intervjua sa domenskim ekspertom, mr Miodragom Sljukiem, dipl. oecc. Izgraen je konceptualni model ES i osmisljen dizajn baze znanja. Postujui ogranicenja razvojnog alata, implementacija je obavljena kroz modularnu arhitekturu, koja obuhvata ES namenjene oceni profitabilnosti, bilansne i finansijske moi, ekonomicnosti, solventnosti i leveridza, kao i strukture prihoda i rashoda organizacije.

"Study of New Natural Substances with Antimicrobial Action against Causative Agents of Bacterial Infections in Women, with Special Emphasis on the Causative Agents of Spontaneous Miscarriage and Premature Birth''

From 161 pregnant women at a gestational age range of 16-19 weeks, who were admited at Clinic of Gynecology and Obstetrics in Novi Sad because of early amniocentesis indicated by geneticist, the blood samples and samples of amniotic fluid were taken. Standard markers of infection were determined in blood samples (CRP, white blood cell count, erythrocyte sedimentation). The levels of IL-4, IL-6, IL-8, IL-10, IL-13 were determined in serum and amniotic fluid samples. We found that there is homeostatic balans between investigated cytokines with slightly predominant proinflammatory immune response. Also, the amniotic fluid levels of IL-8 and IL-10 were significantly different in pregnant women with infection compared with healthy pregnant women. Parameters of oxidative stress (activity of superoxide dismutase, xanthine oxidase, glutathione peroxidase, glutathione reductase, extent of lipid peroxidation, reduced glutathione content) were determined in amniotic fluid samples. Values of investigated parameters were detectable, but 10 to 1000 times lower than in blood hemolysate. Antimicrobial activity of essential oils of caraway, coriander, aniseed and peppermint is evaluated on the bacterial strains isolated from genital fluid. The strongest antimicrobial effects exhibited peppermint essential oil. All investigated essential oils increased the effects of selected comercial antibiotics. Reference:

''Iznalazenje novih prirodnih supstanci sa antimikrobnim delovanjem kod uzrocnika bakterijskih infekcija kod zena, sa posebnim osvrtom na uzrocnike spontanih pobacaja i prevremenih poroaja''

Kod grupe od 161 trudnice od 16 do 19 nedelje gestacije koje su primljene na Kliniku za ginekologiju i akuserstvo u Novom Sadu, radi rane amniocenteze koja je indikovana od strane geneticara, uzeti su uzorci krvi i amnionske tecnosti. Iz uzoraka krvi su uraeni standardni markeri infekcije (CRP, broj leukocita, sedimentacija eritrocita). U uzorcima seruma i plodove vode odreeni su nivoi IL-4, IL-6, IL-8, IL-10, IL-13. Utvreno je da postoji homeostaza izmeu proinflamatornih i antiinflamatornih citokina, sa malom predominacijom proinflamatornog imunog odgovora. Takoe, dobijene su statisticki znacajne razlike u nivou IL-8 i IL-10 u plodovoj vodi trudnica sa infekcijom u odnosu na zdrave trudnice. U amnionskoj tecnosti trudnica odreeni su parametri oksidativnog stresa (aktivnosti enzima superoksid-dizmutaze, ksantin-oksidaze, glutation-peroksidaze, glutation-reduktaze, glutationS-transferaze, intenzitet lipidne peroksidacije, sadrzaj redukovanog glutationa). Dobijene su merljive vrednosti ovih parametara, ali su od 10-1000 puta nize u odnosu na vrednosti u hemolizatu krvi. Odreeno je antimikrobno delovanje etarskih ulja kima, korijandera, anisa i mente na izolovane bakterijske sojeve iz genitalnog sekreta. Najjace antimikrobno delovanje ispoljilo je etarsko ulje mente. Sva ispitivana etarska ulja pojacala su delovanja odabranih komercijalnih antibiotika.

''Dosage Regime for Antibacterial Drugs in the Function of Pharmacodynamic Parameters''

During previous research year, we continued with activities on collecting and analyzing data of content of the home pharmacies in Novi Sad, with special interest in families with small children. We compared results with centers in the Slovakia and the Czech Republic in the field of selfmedication within the framework of started Serbian-Slovak-Czech project. We conducted a study of content of home pharmacies in Slovakia, town Kosice, with emphasis on the use of antibiotics. Holders of the partnership are prof. Vladimir Krcmery and prof. Miron Sramka. The initial results of investigation of resistance of pathogens that cause outhospital infections on the territory of South Backa County showed high incidence of multiresistant outhospital strains of P. aeruginosae, Acinetobacter spp, coagulase negative staphylococcus, which indicates on the transmission of infection from the hospital to out-patient environment and also spreading of infections caused with multiresistant strains out of hospital. The investigation of the type and duration of antibiotic prophylaxis in hospitals for surgery within the framework of started multinational project which involved Surgery clinics of six countries, including the Surgery Clinic in Novi Sad, shows that, in general, the same antibiotics are using for prophylaxis in surgery in all Balkan countries. The difference is only in the length of prophylaxis among these states, where irrationally long postoperative use of antibiotics responsible for whole situation of resistance to mentioned drugs. Holder of the partnership is prof. P. Papaioannidou. References:

''Dozni rezim antibakterijskih lekova u funkciji farmakodinamskih parametara''

U toku prethodne istrazivacke godine, nastavljeno su aktivnosti na prikupljanju podataka i analizi stanja kunih apoteka na teritoriji Novog Sada, sa posebnim naglaskom na porodice sa malom decom. Rezultati su uporeeni sa centrima u Slovackoj i Ceskoj u oblasti samomedikacije u okviru zapocetog Srpsko-Slovacko-Ceskog projekta. Nosioci od strane inostranih partnera su prof. Vladimir Krcmery i prof. Miron Sramka. Pocetni rezultati ispitivanja rezistencije uzrocnika vanbolnickih infekcija na teritoriji Juznobackog okruga je pokazalo visoku ucestalost multirezistentnih vanbolnickih sojeva P. aeruginosae, Acinetobacter spp, koagulaza negativnog stafilokoka, sto ukazuje na prenosenje infekcije iz bolnicke u vanbolnicku sredinu i sirenje infekcije multirezistentnih sojeva i u vanbolnickoj sredini. Ispitivanje vrste i duzine trajanja antibiotske profilakse na klinikama za Hirurgiju u okviru zapocetog multinacionalnog projekta koji je obuhvatio klinike za hirurgije sest evropskih zemalja, ukljucujui i Kliniku za hirurgiju u Novom Sadu, pokazuje da se generalno isti antibiotici koriste za profilaksu u hirurgiji svih zemalja Balkana, razlika je samo u duzini trajanja profilakse izmeu drzava gde je neracionalno duga postoperativna primena antibiotika odgovorna za ukupno stanje rezistencije na navedene lekove. Nosioc od strane inostranog partnera je prof. P. Papaioannidou.

Branimir Guduri, Marica Miokov, Milan Breberina, Dusan Jovanovi, Tomislav Petrovi Academy of Sciences and Arts of Vojvodina, Novi Sad, Serbia ''Early Detection of Colon Carcinoma in Different Ethnic Groups of Vojvodina. A Pilot Study'' In the previous year of screening for Colorectal carcinoma with Hemocult testing, additional 1236 persons, that are altogether 5339 persons or (0,73%) asymptomatic inhabitants older then 50 years of age in Vojvodina, (according to the Republic statistical data 729.569 were recorded for 2006y.) were screened. That number is allmost identical to the number of last year screened, as planed spread of early detection to the Oncological Dispanser in Sombor failed due to financial problems. So, 1200 persons screened per year are optimal number in so organized screening campaine. Further elevation of this number ask for more pariticipants of general practitioners on primary health level, or reorganisation of the screening protocol. However, performing screening on more then 5000 persons are highly statistically significant sample number for the pilot program, and resuts obtained are considered as valuable proof for spreading of sceening to the seminational program. In april of last year Ministary of Health of Serbia published National program rules for screening of colorectal cancers, and using these directive with obtained results in this project, together with good will and finacial basis, can surrely be starting point for organizing screening in whole Vojvodina population. In 2009/10 year 10 (ten) aditional cancers, 41 cancer in whole period of screening had been found (0,76%), but the number of removed polyps had been much lower, (only 11 versus 23 in last year) due to postpoining removal of the found polyps for second "interventional colonoscopy" practised in last year. That produced long "waiting lists", and substantial numbers of patient refused to participate in scond colonoscopy. Beside these problems, 72 (1,3%) polyps removed in whole period of screening, are very valuable numebr as excisions of polyps as precancerous lesions are primary prevention of colorectal cancers. Moreover, analyzing cancers discovered during this period, acording to the epidemiological situation in Vojvodina, with incidence od 120,3 per 100.000 inhabitans older then 50 years, (for 2006y.), calculated obtained incidence during these screening with 768 per 100.000 that are more then six times superior then usualy reported, and highly justify these screening campaine. However, beside this successes on detection level, in colonoscopic diagnosis of the lesions appeared problems, either due to the inadequate equipment or inexperienced endoscopiests, as inexplicable high number of the patients with postive HKT tests refuse further diagnosics due to, presumably long waiting lists (in last year up to ONE THIRD OF HKT POSSITIVE) . Furthermore, lack of video confirmation of the intubation to the cecum, as well as, inability to electroexcisse of the polyps (specialy larger then 1 cm in diameter) in the same setting, neccesary for screening programs, ask for solution, before national screening program can be proposed. New measures had to be considered (Starting of planed endoscopy school, better renewal with necessary equpment ect.) or even planing of new research of problems of implementation of results of these sreening of whole Vojvodina population. For evaluation of the corelation between incidence of colorectal cancers and nutritional habits of the population, as it was pointed out in previous reports, larger numbers of diagnosed cancers versus patients screened are necessary, and that justify continuation of this program of CRC screening in the future.

Kao sto se vidi, broj ispitanika u ovoj godini je bio priblizno identican proslogodisnjem, jer nije doslo do planiranog ukljucivanja Onkoloskog Dispanzera iz Sombora, zbog neresenih finansija. Zato se broj od oko 1200 pregledanih godisnje moze smatrati optimalnim za ovako organizovano istrazivanje i njegovo poveanje bi bilo mogue samo ukljucivanjem novih ucesnika (Lekara opste medicine na primarnom nivou) ili pak reorganizacijom celog istrazivanja. Ovaj broj od preko 5000 pregledanih asimptomatskih osoba starijih od 50 godina starosti, predstavlja visoko predikciono - statisticki znacajan uzorak za pilot istrazivanja. Zato se rezultati koji proiziu iz ove analize mogu smatrati dovoljnim za opravdaje zapocinjanja ranog otkrivanja karcinoma debelog creva na mnogo sirem pa i seminacionalnom nivou. Posto je proslog aprila u sluzbenom listu objavljena Nacionalna strategija ranog otkrivanja Karcinoma debelog creva od strane Ministarstva zdravlja Republike, ovi nalazi uz prisustvo dobre volje i obezbeenja finansiske baze mogli bi biti pokretac organizovanja skrininga na nivou cele Pokraine. U 2009/10 godini otkriveno je jos 10 deset karcinoma sto ukupno cini 41 karcinom otkriven u celom istrazivanju odnosno (0,76%), dok je prijavljen znatno manji broj uklonjenih polipa (svega 11 u odnosu na 23 prosle godine). Ovo je posledica uvodjenja prakse da se polipi ne otklanjaju u toku prve kolonoskopije kada su dijagnostikovani, ve se zakazuju za naknadnu "interventnu kolonoskopiju". Time oni prelaze iz grupe skriniranih na redovne preglede i stavljaju se na liste cekanja koje su zbog velike duzine dovodile do velikog broja odustajanja pacijenata od ove intervencije. Zato se eventualno javljanje polipa kao prekanceroza koje je ranije bilo redovno evidentirano, sada moze uzeti samo uslovno a nikako kao pravi rezultat incidencije tih lezija kod ispitavanih. Cak uzimajui i ovo u obzir, broj od 72 polipa koji su uklonjeni i histoloski verifikovani u toku celog ispitivanja je vrlo visok (1,34% pregledanih) i dalje opravdava izvoenje skrininga. Analizirajui pak, broj otkrivenih karcinoma debelog creva u odnosu na epidemioloske podatke incidence ovog obolenja u Vojvodini koja za 2006 godinu (poslednja dostupna) za osobe starije od 50 godina, iznosi 120,3 na 100.000 vidi se da u okviru ovog istrazivanja, ta preracunata incidenca je 768 na 100.000, odnosno preko sest puta vea no pri redovnom otkrivanju. Ipak, pored ovih uspeha na detekcionom nivou kod kolonoskopske dijagnostike pojavili su se problemi kao posledica neadekvatne opreme i/ili nedovoljne obucenosti izvodjaca, jer je neprihvatljivo veliki broj pacijenata sa pozitivnim HKT testom, odustao od daljeg ispitivanja zbog dugackih lista cekanja ( u ovoj godini SKORO TREINA OSOBA SA HKT POZITIVNIM TESTOM NISU DOVRSILI KOLONOSKOPSKO ISPITIVANJE ZBOG DUGACKIH LISTA CEKANJA). Isto tako, video potvrda kompletnosti kolonoskopije JE IZUZETNO RETKO izvodjena, a i pomenuti problemi kod primarne elektro-excizije polipa traze resenje ovih problema pre preduzimanja nacionalnog programa skrininga. Odlaganje zapocinjanja rada "Skole vido-endoskopije", kao i nedovoljna nabavka kolonoskopa za sve Zdrastvene centre Vojvodine, predstavlja skup negativnih cinjenica, koje mozda traze i novo istrazivanje problema implentacije ovih dobrih rezultata dobijenih u okviru ovog istrazivanja na primarni nivo zdrastvene zastite pre zapocinjanja nacionalnog programa. Najzad, kao sto je to istaknuto u proslom izvestaju za odgovor o korelaciji zivotnih navika i nastanka karcinoma debelog creva, potreban je znantno vei broj otkrivenih karcinoma, pa to zahteva nastavak istrazivanja.

''Influence of Hormonal Therapy on the Increase of Fertile Potential in Children with Undescended Testes''

During the continuation of the project, and over the periof from March 2009 - March 2010 a total of 135 patients underwent orchiopexy and testicular biopsy in Vojvodina. All biopsies were fixed in cold 2% gluter-aldehyde in phosphate buffer, according to the research protocol. Biopsies were sent to Switzerland for further preparation and patohistologic expertize. Part of the biopsies biopsies were prepared in Serbia in Institutions equipped for electron microscopy. Findings were supervized by Prof. Hadziselimovic in Liestal, Switzerland. Out of 135 patients, 44 completed the biopsy, and finished hormonal therapy according to the accepted research protocol. Another 39 patients underwent surgery and biopsy, results of expertize are obtained, parents are informed, and the patients who are in need started hormonal therapy. Additional 25 patients have completed surgery and analysis of the biopsies, and the process of informing the patients is ongoing. We have recently sent another 25 biopsies in Switzerland and we are awaiting results. Results obtained so far showed need for postoperative hormonal therapy in 82.5% of the patients, what is quite similar to the results obtained over the past several years. We have compared those results with results of biopsies of undescended testes from other regions (USA, Switzerland), and we have found a statistically significant differences, as we have already published in Acta Paediatrica. We hope to find causes of these discrepancies. Besides above mentioned results we have also started with analysis of spermiograms of healthy adolescents and adolescents treated in childhood for undescended testes, but the nuber of patients is until now to low to allow valid statistical analysis. We expect to be able to do that til the end of the next year. References:

''Uticaj hormonalne terapije na poveanje fertilnog potencijala dece sa nespustenim testisima''

U nastavku odobrenog projekta, a u periodu od marta 2009 godine do marta 2010 godine u vojvoanskim zdravstvenim ustanovama u kojima se vrsi tretman nespustenog testisa uzeto je 135 biopsija testisa. Svi preparati su fiksirani u 2% gluteraldehidu u fosfatnom puferu, a po predvienom protokolu istrazivanja. Preparati su shodno predlozenoj proceduri upueni u drzavu Svajcarku radi dalje pripreme i patohistoloske ekspertize. Deo preparata je pripremljen u ustanovama u kojima se radi elektronska mikroskopija u republiuci Srbiji. Svi preparati su poslati u Svajcarsku kod Prof. dr Hadziselimovia na ekspertizu. Od toga je za 44 pacijenta dobijen nalaz putem elektronske poste, i svi pacijenti su u zavisnosti od rezultata obavesteni, a pacijenti koji su imali losu histolosku sliku su zapoceli hormonalni tretman u skladu sa prihvaenim protokolom lecenja. 39 pacijenata je kompletno obraeno, roditelji su obavesteni a proces hormonalne terapije kod pacijenata kod kojih je potreban je u toku. Dodatnih 25 pacijenata je kompletno obraeno u Svajcarskoj, i rezultati su poslati elektronskom postom, a proces obavestavanja roditelja je u toku. Bioptati 27 pacijenata su nedavno poslati u Svajcarsku, i ocekujemo u dogledno vreme da nam stignu rezultati ekspertize. Do sada dobijeni rezultati su ukazali na potrebi za dodatnim postoperativnim hormonalnim tretmanom kod 82.5% pacijenata, sto je veoma slicno rezultatim dobijenim tokom prethodne dve godine. Mi smo ve uporeivali dobijene rezultate sa rezultatima analize bioptata nespustenih testisa pacijenata iz drugih regiona, i ustanovili smo da postoji statisticki znacajna razlika u odnosu na njih. Ove rezultate smo i objavili i casopisu Acta Pediatrica. Nadamo se da emo biti u mogunosti da ustanovimo uzroke ove diskrepance u histologiji nespustenih testisa pacijenata iz Vojvodine u odnosu na slicne pacijente iz drugih regiona (Svajcarska, SAD). Osim gore navedenih rezultata zapoceli smo analize spermograma zdravih adolescenata, kao i adolescenata kojima je u detinjstvu raena operacija nespustenog testisa. Broj pacijenata je za sada nedovoljan da bi se adekvatno odradila statisticka analiza rezultata, pa ocekujemo da emo biti u mogunosti da ove rezultate pripremimo za sledeu godinu.

''Biochemical Heterogeneity of the Brain Parenchyma: 1H MR Spectroscopic Study of the Effect of Aging and Region on Metabolites Concentration in the Brain''

Purpose: To determine metabolic differences in hippocampi of the patients with juvenile myoclonic epilepsy (JME) and healthy controls by using magnetic resonance spectroscopy (MRS). Methods: We performed 3D multivoxel MRS study on 1.5T scanner of both hippocampi (3 voxels in the head, 3 in the body and 3 in the tail of each hippocampus) of 26 patients with JME (26.5 ± 7.5 years old; 10 females; range 18 ­ 50) with normal brain MRI, treated at the Institute of Neurology, Clinical Center of Serbia, and 19 age and sex matched controls. Three dominant signals were measured: Choline (Cho), Creatine (Cr) and N-Acetylaspartate (NAA) and expressed as ratios of Cho/Cr, NAA/Cr, NAA/Cho and NAA/(Cho+Cr). MRS was performed in interictal period for both GTCS and myoclonic seizure types (>48 hours) in all patients. Results: Patients suffered JME 11.8 ± 8.5 years (range 1 ­ 33) prior to the study. A positive family history of epilepsy in close relatives was found in 4 patients. Ratios of NAA/Cr, NAA/Cho and NAA/(Cho+Cr) in hippocampi of patients with JME and healthy controls were significantly different in head, body and the tail. Discussion: Although not previously recognized as a part of epileptogenic network, our results suggest that hippocampus, well known as a key player in focal epilepsies, may have certain role in the pathogenesis of JME.

''Biohemijska heterogenost mozdanog parenhima: 1H MR spektroskopska studija uticaja starenja i regije na koncentracije metabolita mozga''

Cilj istrazivanja je bilo ispitivanje razlika u metabolizmu hipokampusa protonskom magnetnorezonantnom spektroskopijom kod pacijenata sa juvenilnom mioklonickom epilepsijom (JME) u poreenju sa grupom zdravih dobrovoljaca. Metode: Precizna prostorna lokalizacija volumena od interesa za spektroskopiju je bazirana na ortogonalnim trodimenzionalnim snimcima glave, debljine 3 mm. Tro-dimenzionalni (3D CSI) PRES volumen od interesa velicine 4×4×4 cm je postavljen u regiji levog i desnog hipokampusa posebno. Kod svake osobe je izvrsena analiza spektara na 18 lokacija (po 3 u glavi, telu i repu levog i desnog hipokampusa ). Analizirana su tri dominantna signala: Holin (Cho), Kreatin (Cr) i N-acetilaspartat (NAA). Koncentracije metabolita su izrazene relativno, u odnosu na kreatin kao interni standard. U okviru matematicko-statisticke obrade podataka primenjena je: faktorska analiza, deskriptivna statistika, diskriminantna analiza i t test. Rezultat: Detektovano je znacajno sizenje NAA/Cr, NAA/Cho and NAA/(Cho+Cr) u telu i repu oba hipokampusa (p<0.05) kod bolesnika sa JME. Diskusija: Ovim istrazivanjem je dokazano postojanje neurohemijskih promena u hipokampusu kod JME, sto do sada nije objavljeno u literaturi.

''Responses of the Human Body to Physical Stress and Limits of Compesatory Mechanisms''

We continued with the dynamometric and ergometric testings of athletes and non-athletes and increased the representativeness of the sports database created at the Department of Physiology. In collaboration with our Russian partner from the Institute of Normal Physiology of the Moscow Medical Academy we published an article related to cognitive, psychological and vegetative changes after of psycho-physical relaxation. In collaboration with the Research Centre for Society and Health, BUCKS New University, Buckinghamshire, UK, lead by prof David Brodie and the Center for imaging diagnostics in Sr. Kamenica we prepared an article on the functional and morphological changes during a twelve-week controled physical training. On the topic of heart rate recovery one article was accepted for publishing in the Journal of Sports Science nd Medicine. The focus of this segment of our investigation was on heart rate variability and regulatory mechanisms of cardiovascular functions in rest, exercise and recovery. References:

''Blidness and Low Vision and the Importance of Cataract Surgery for Decrease of Treatable Blindness in Vojvodina''

PURPOSE: To analyse binocular and monocular visual status of Vojvodinian population, and significance of refractive error correction, cataract surgery and diabetic retinopat risk factors controle for decreasing main vision impaired ocular disease. METHODS: The cross sectional, bifasic stratified random sampling was analised.The sample of 502 subjects was examinated by ophthalmologist including VA testing:natural, with one's glasses and BCVA. Paralele investigation was performed as the multicenter study of cataract suirgery in hol the region. The clinical follow up of 166 DM patients was performed according to the most common risk factors for vision loss. RESULTS: Out of 48,8% ubjects with satisfactory vision status (0,5) 51,2% of total 502 subjects number was vision impaired (0.3). When applying the adequate refractive correction the vision impaired simple decreases from 51.2 to 24.5% (7.6% blind and 16.9% low vision). Low quality vision of 24.3% subjects is due to the uncorrected refracted errors. The mean age of the blind individuals is 74.5 years and 76.0 years for the low vision group, where both are significantly higher than the mean age of the whole sample (68.2 years). Monocular low vision (9.8%) and blindness (7.2%) had an impact on vision quality of the population in 17% of the subjects. Incidence of blind and low vision individuals increases with age but decreases with higher education levels. Prevalence of visual handicap (BCVA 0.3) in people older than 50 years of age is 1.39%, and is the highest in the group older than 70 years of age. But according to the WHO categorization due to good vision in the other eye this could not be categorized as visual disability. Vojvodina cataract study in 2009 shows a steady number (4946 )of surgery compared to previous years, but also shows a decrease of blind (10.4%) and low vision (16.4%) individuals waiting for cataract surgery. Cataract surgery of the other eye was performed in 28.5% of patients. The Quality of cataract operations was increased with 71,6 % of procedure performed with phacoemulsification technique and the implanted IOLs were mostly hydrophilic and silicon lenses. The overall percentage of intraoperative complications was 3.9%. High comorbidity percentage (66.2%) was mostly associated with cardiovascular disease (44.6%) and diabetes mellitus (21.7%). In clinical case study of DR patients the 6.6% were blinde and 11% low vision impaired. The most important risk factors in the whole group were high blood sugar levels (mean HbA1c 8,5%) and hypertension in 71% of patients. CONCLUSION: The magnitude of visual impairment in Vojvodina population over 50 years of age is higher then in European countries causing by treatable or avoidable diseases as the uncorrected refractive error, cataract and diabetic retinopaty.

"Slepilo i slabovidost i znacaja hirurgije katarakte za smanjenje izlecivog slepila u Vojvodini"

Analiza randomiziranog uzorku od 502 ispitanika prosecno starih 68,2 godina, ukazuje na dobar vida (0,5 i vise), kod 48,8% stanovnika Vojvodine, a kod 51,2% on je oslabljen (0,3 i manje) Nedovoljan kvalitet vida ima cak 24,3% stanovnika zbog nekorigovane dioptrijske greske. Ovaj broj vidom onesposobljenih, uz dioptrijske naocare se smanjuje cak na polovinu sa 51,2% na 24,5% gde preostaju 7,6% slepih, a 16,9 % slabovidih. Broj slepih i slabovidih osoba se poveava sa starosu, a opada sa visim stepenom obrazovanja. Prevalenca vidne nesposobnosti (BCVA 0,3 i manje) od 1,39 % kod stanovnistva preko 50 godina, najvea je u grupi preko 70 godina starosti. Starosni prosek za slepe je 74,5 g. a slabovide je 76,0 g. sto je signifikantno vea starost od proseka svih ispitanika (68,2 g.). Jednostrana slabovidost (9,8%) i slepoa (7,2%) remete kvalitet vida cak u 17% vojvoana ali dobar vida na parnom oka iskljucuje njihovu kategorizaciju u vidom onesposobljene( po SZO) . Studija o lecenju katarakte u 2009g. pokazuje da se ukupno broj od 4.946 operacija u javnim hirurskim centrima u Vojvodini odrzava na nivou iz prethodne dve godine. Najvise operacija je uraeno u Novom Sadu- Klinicki centar Vojvodine 1.831 (37%). Zatim, sa preko 700 operacija, slede ocna odeljenja u Sremskoj Mitrovici (757 15,3%), Subotici (751 - 15,2%) i Pancevu (734 - 14,6%) a Sombor, Zrenjanin i Vrbas ima znacajno manje. U ovom periodu se meu operisanima znacajno smanjio broj slepih (10,4%) i slabovidih (16,4%) osoba sa kataraktom u odnosu na pocetnu 2006g. U treini obolelih (28,5%) operacija katarakte je izvrsena i na drugom oku. Analizom kvaliteta zivota pre i nakon operacije katarakte,VQOL-index se bitno ne menja kod operacije jednog oka koja pruza kvalitet zivota kao i operacija na oba oka. Najvei broj je operisan metodom fakoemulzifikacije sa ugradnjom savitljivog vestackog sociva (3544 -71,6%), a manji manuelnom ekstrakapsularnom metodom(1221 - 24,7%). Najvise je ugraeno hidrofilnih i silikonskih intraokularnih sociva. Detaljnom analizom rezultata 785 dvomesecnih operacija (oktoba-novembar 2009), registruje se znacajno manja ucestalost intraoperativnih komplikacija (3,9%),u odnosu na prethodni period (10.4% i 8,5%) .Zabelezen je visok stepen komorbiditeta (66,2%) kod operisanih od katarakte, najvise kao kardiovaskularna oboljenja (44,6%) i seerna bolest (21,7%). Praenjem 166 dijabeticara sa prosekom od 17 godina trajanja DM, naeno 6,6% (11) slepih i 11%( 18) slabovidih sa najtezim oblicima PDR. Vodei rizik faktori koji dovode do gubitka vida u svih su bili losa kontrola DM sa dvomesecnim prosekom seera u krvi od HbA1c 8,5% i arterijska hipertenzija u 71%, 117 ispitanika.To postavlja potrebu novog programa mera za sprecavanje slepila od ove preventibilne bolesti.

"The Effect of Medicamentous Therapy and Functional Electrotherapy on Spasticity and Quality of Life in Children with Cerebral Palsy"

Spastiic form of cerebral palsy (CP) is one of the most common causes of physical disability in early childhood. The main objective of this study was to establish the effects of botulinum toxine type A (BTX-A) and functional electrotherapy (FET) on the quality of life of children with CP. The study is largely prospective. The sample has included 41 patients in which we injected for first time BTX-A. Results indicate that after application of BTX-A has been increase range of motion in all segments of the lower extremity and reduce of spasticity was in all observed time intervals (2 weeks, 1.5, three and five months after treatment). It was significantly increased abduction of hips (p <0.05) and popliteal angle (p <0.05). The attitude of parents investigated by analyzing the questionnaire which was filled by 20 parents, at least 5 months after the conducted treatment:75% of parents noticed the reduction of spasticity in treated muscles, the improvement of motor function 80% and quality of motor skills 85% of patints. In 7 patients with hemiparesis after application of FET results show that there has been improvement of segment mobility, grip, support and postural reactions in treated patients. Application of BTX-A and FET-a leads to improved functional status of treated patients, and therefore the quality of life of children with CP. References:

"Uticaj medikamentozne terapije i funkcionalne elektroterapije na spasticnost i kvalitet zivota kod dece obolele od sindroma decije cerebralne paralize"

Spasticni oblik decje cerebralne paralize (CP) je jedan od najcesih uzroka fizicke nesposobnosti u ranom detinjstvu. Osnovni cilj istrazivanja bio je da se ustanove efekti botulinum tokisn tip A (BTXA) i funkcionalna elektroterapija (FET) na kvalitet zivota dece sa CP. Studija je veim delom prospektivna. Uzorak je do sada obuhvatio 41 pacijenta kojima je prvi put injiciran BTX-A. Rezultati ukazuju da je nakon primene BTX-A doslo do poveanja obima pokreta u svim segmentima donjih ektremiteta kao i smanjenja spasticnosti u svim posmatranim vremenskim intervalima (2 nedelje, 1,5, tri i pet meseci nakon tretmana). Statisticki znacajno bilo je poveanje abdukcije u kukovima (p<0,05) i poplitealnog ugla (p<0,05). Stav roditelja ispitan je analizom upitnika koji je popunilo 20 roditelja, najmanje 5 meseci nakon sprovedenog tretmana: 75% roditelja navodi da su uocili smanjenje spasticnosti tretiranih misia, poboljsanje motorickih funkcija 80% kao i kvaliteta motoricke vestine 85% anketiranih roditelja. Kod 7 pacijenata sa hemiparezom nakon primene FET-a rezultati pokazuju da je doslo do poboljsanja segmentne pokretljivosti, hvatova, oslonca i polozajnih reakcija kod tretiranih pacijenata. Primena BTX-A i FET-a dovodi do poboljsanja funkcionalnog statusa tretiranih pacijenata, a samim tim i kvaliteta zivota dece sa CP.

"Developmental Dysplasia of Hip Tele-Ultrasound Screening ­ Feasibility of Assisted Ultrasound Dyagnosis in a Real Time, on Distant, through Internet Connection of Low Band Width"

Telemedicine offers the opportunity to incorporate standard and innovative procedure. Applied software and hardware solutions through the Internet low bandwidth connections, carried out the teleultrasound screening of developmental hip disorders, in real time, with follow-up ultrasound examination (video stream). Analysis of the used software package were based on the Qt programming environment and VLC multimedia library. Subjective assessment of the quality of transmitted video was conducted, which was ranked from 0 to 3, so that 0 indicates the connection termination and loss of video signal, 1 indicates a poor quality video, 2 indicates good quality video and 3 indicates the excellent quality video. Performed measurements included 280 tests with codecs WMW1, WMW2, DivX2, DivX3, Theora, Dirac and H263. For the each codec was performed 40 tests with 8 different values of bandwidth in the range of 32-400 kbps and 5 different values Framerate in the range of 1-10 fps. Dirac codecs, Theora and H263 did not give satisfying results while other codecs fulfilled the needs of clinical parameters Framerate 3fps and Bandwidth > 160kbps for codecs and WMW2 DivX3 or > 224kbps for codecs and WMW1 DivX2. Over 840 tests measured the delay between video sender and receiver and on this occasion it was determined that it is moving in the range of 2.046 to 2.544 seconds. We designed a conceptual solution in overcoming the effects of delays in transmission of ultrasound images remotely, using appropriate software modifications. New solutions are designed to conduct remote ultrasound examination by trained sonographers through navigation. Teleultrasound screening, using low-bandwidth Internet connection can, with the used software package, provide an adequate ultrasound image and video, which is the basis for the clinical application of this model.

''Intracellular Markers of Oxidative Stress in Women Of Generative Age''

The aims of the subproject «Markers of oxidative stress in normal pregnancies and pregnancies complicated with preeclampsia", of the project INTRACELLULAR MARKERS OF OXIDATIVE STRESS IN WOMEN OF GENERATIVE AGE were to establish concentrations of markers of oxidative stress (TBARS, SOD, HORAC, ORAC) and the level of their activity in normal and preeclamptic pregnant women as well as intercorrelation of the markers of oxidative stress with other features of preeclampsia and among themselves. Nonrandomized, prospective study of markers of oxidative stress was done on pregnant women with preeclampsia (PEE) (28 women, group I) and healthy pregnant women (29 women, group II), as pairs matched by gestational age. There was no difference in age (p0,116) nor gestation between the two groups (p0,721). Results: there is no statistical difference in concentration of Thiobarbituric Acid Reactive Substances (TBARS) (p0,107), superoxid dismutase (SOD) (p0,093), nor it's enzyme activity (SOD%) (p0,114), although there is clinical difference (SOD I 666, II 379, SOD% I 24%, II 17,7%). Statistical difference is significant in markers of Hydroxyl Radical Antioxidant Capacity Activity (HORAC netAUC) (p< 0,001), and HORAC MGAEL (p0.002), but no difference was found in Oxygen Radical Absorbance Capacity (ORAC NetAUc p0,882, ORAC eqTrolox p0,680). In group I there is correlation between diastolic and systolic arterial pressure (TAD/TAS) (r 0,622, p<0,001), and proteinuria and TAS (r 0,450, p 0,027). There is negative correlation between TAS and SOD (r - 0,378, p 0,047), as well as SOD% and TAS (-0,392, p 0, 039), HORACnet and TAS (r -0,577, p 0.001), HORACGael and TAS (r - 0.582, p 0,001). Although the results of the study do not give the possibility of final conclusion of the role of oxidative stress in pathogenesis of PEE, the results of differences in the levels of markers of oxidative stress in pregnancies with PEE are important for further investigations. Conclusion: the aims of the studz are fullfilled. Although the results of the study do not give the possibility of final conclusion of the role of oxidative stress in pathogenesis of PEE, the results of differences in the levels of markers of oxidative stress in pregnancies with PEE are important for further investigations. Prospective nonrandomized study was conducted on the Clinic for infectious diseases KC Vojvodina during 2009. Aims of the study were to evaluate the influence of 2 months multivitamin and multimineral suplementation on oxiredox homeostasis, symptoms of CFS (FFS) and quality of life (Health Related Quality of Life - SF 36) among female patients of reproductive age. We included 38 women with CSF of whom 35 finished the study following including and excluding criteria. We found significant dicreasing of concentrations and activity of SOD after the suplementation. Avarage concentrations of antioxidative markers were elevated after suplementation, but the difference was not statisticaly significant. FibroFatigue score was significantly lower after suplementation especially for reduction of muscle tension, fatigue, autonomic nerve symptoms, headake and subjective impression of infection. We found significantly improved some aspects of quality of life of our patients, due to general improved health, decreised pain, influence on psychological stability, decreised exostering and fatigue and positive effects on social life of patients.

''Intracelularni markeri oksidativnog stresa kod zena generativne dobi''

Nerandomizovano, prospektivno ispitivanje markera oskidativnog stresa kod trudnica sa preeklampsijom (PEE) uradjeno je na 57 uzoraka - ispitivana grupa sa PEE (I) 28 zena, kontrolna (II) 29 zdravih trudnica. Svaka trudnica I grupe imala je svoj par u grupi II odgovarajue gestacijske starosti. Nije bilo razlike u starosti (p0,116) niti u gestaciji dve grupe (p0,721). Rezultati ispitivanja markera okdsidativnog stresa: nema statisticke razlike u koncentraciji tiobarbituricne kiseline (p0,107), superoksid dizmutaze (p0,093), ni njene enzimske aktivnosti (p0,114), mada postoji razlika sa klinickog stanovista kod oba parametra (SOD I 666, II 379, SOD% I 24%, II 17,7%). Statisticka razlika je znacajna kod markera HORAC netAUC (p< 0,001), i HORAC MGAEL (p0.002). Kod markera ORAC nema statisticke razlike (ORAC NetAUc p0,882, ORAC eqTrolox p0,680). U grupi I ima korelacije izmedju dijastolnog i sistolnog pritiska (TAD/TAS) (r 0,622, p<0,001), kod proteinurije i TAS (r 0,450, p 0,027). Izmedju TAS i markera stresa SOD ima negativna korelacija (r - 0,378, p 0,047), kao i kod SOD % i TAS (-0,392, p 0, 039). Negativna korelacija postoji izmedju HORACnet i TAS (r -0,577, p 0.001), kao i kod HORACGael i TAS (r - 0.582, p0,001). Mada rezultati istrazivanja ne daju mogunost konacnog zakljucka o ulozi oksidativnog stresa u patogenezi preeklampsije, za dalja istrazivanja vazni su rezultati o razlikama nivoa enzimskih aktivnosti u oksidativnom stresu kod trudnica sa PEE. Na Klinici za infektivne bolesti KC Vojvodine sprovedeno je nerandomizovano prospektivno istrazivanje o uticaju multivitaminsko mineralne suplementacije u trajanju od dva meseca na oksiredoks homeostazu i simptomatologiju, te kvalitet zivota pacijentkinja kod kojih je dijagnostikovan Sindrom hronicnog umora. U studiju je ukljuceno 38 zena - 35 je zavrsilo istrazivanje. Utvrdjena je statisticki znacajna razlika izmedju koncentracija i aktivnosti superoksid dismutaze pre i posle suplementacije u smislu smanjenja koncentracija, odnosno aktivnosti. Iako su srednje vrednosti antioksidativnog kapaciteta protiv peroksil radikala (ORAC) i hidroksil radikala (HORAC) bile vise u grupe posle suplementacije, razlika nije bila statisticki znacajna. Subjektivne tegobe bolesnica praene kroz FFS statisticki su se znacajno smanjile nakon suplementacije u ukupnom skoru.,kao i u domenu: misine napetosti, umora, glavobolje, autonomnih poremeaja i subjektivnog oseaja postojanja infekcije. Korelacija izmedju markera oksiredoks homeostaze i FFS nije bila statisticki znacajna. Dobijeno je statisticki znacajno poboljsanje kvaliteta zivota u domenima koji se odnose na poboljsanje zdravlja, smanjenja bolova, uticaja na smirenost i spokojnost, smanjenje iscrpljenosti, smanjenje umora i uticaja psihofizickog zdravlja na drustvene aktivnosti pacijentkinja.
