The concept of community readiness for preventive action
Authors: Citic-Popovic Branislava , Pavlovic-Zunic Vesna
Published: July 2008

Community readiness is defined as the extent to which a community is adequately prepared to develop and implement preventive interventions. The concept makes it possible to provide theoretically and scientifically grounded explanations of inconsistent effectiveness of prevention programs implemented in different communities. The article outlines the history of the community readiness model, its basic components (dimensions and stages) and practical implications - how to assess community readiness, and strategies to improve it.
The antinomies of Christian Zionism
Authors: Boer Roland , Abraham Ibrahim
Published: July 2008

Defining Christian Zionism as conservative Christian support for the state of Israel, and an influential political force, especially in the United States, this article outlines four antinomies of such a position. Firstly, although Christian Zionism argues that it is purely theological, that it follows God?s will irrespective of any politics, and although mainstream Zionism is resolutely political, we argue that such a separation is impossible. Indeed, mainstream Zionism cannot avoid being influenced by Christian Zionism?s political agenda. Secondly, despite the efforts by mainstream Zionism to use Christian Zionism in order to influence US foreign policy in the Middle East, mainstream Zionism is playing with fire, since Christian Zionists wish to convert or annihilate all Jews. Thirdly, Christian Zionism is the ultimate version of anti-Semitism, for it wishes to get rid of Arabs (as hindrances to the Zionist project) and then dispense with Jews. (Both Arabs and Jews are by definition Semites.) Finally, since Christian Zionists are fundamentalist Christians, they must take the Old and New Testaments at their word. However, this position is impossible to hold, and in order to resolve the tension they must resort to the violence of the final conflict, Armageddon.
Constructing reality through music: The example of Richard Wagner’s festival theatre in Bayreuth
Authors: Jeremic-Molnar Dragana
Published: July 2008

In this article the author endeavors to present music as socially powerful and effective art, which has enormous potential to participate in the complex process of constructing reality, especially the reality of "symbolic universe" (in Peter Berger?s and Thomas Luckmann?s meaning of this term). In an attempt to define the role music could play in the process of reality construction, special attention is paid to music?s ability to create temporal and spacial coordinates of a "symbolic universe", as well as to the importance and consequences of belonging to the so-called "community of listeners". In the second part of the article the conclusions are tested by being applied to the audience of Richard Wagner?s Festival Theatre in Bayreuth. The main reason for examining the socially-constructive power of music is found in the fact that Wagner established his theatre with the express purpose of constructing (by optical and acoustical means) an essentially deviant reality of a novel "symbolic universe", reality strong enough to outgrow the reality of everyday life and replace it at the position of paramount - or, in Wagner?s words, "genuine" - reality.
From subculture to scene and tribe: Post-Birmingham approaches to the relationship between youth, music and style
Authors: Stanojevic Dragan
Published: July 2008

The paper discusses the so-called "post-Birmingham approaches" to analyzing the relationship between youth, music and style. Three especially pertinent theoretical approaches are presented: Sarah Thornton?s research based on the concept of "subcultural capital", the concept of "scene" developed by Keith Harris and Will Straw, and "neo-tribalism" borrowed from M. Maffesoli and applied to youth studies by Andy Bennett. All these concepts are based on a critique of subcultural theories conceived and elaborated at CCCS in Birmingham. The author stresses theoretical contributions of the new concepts and through critical insight argues that the notion of subculture is no longer capable of explaining contemporary social reality.
War, plague and exploitation in DR Congo
Authors: Dimcevska Antoaneta , Kecmanovic Sonja , Masanovic Marija
Published: July 2008

Late in autumn 2006 one of the headlines in world media was the first democratic elections in DR Congo. They took place after 30 years of Mobutu Sese Seko?s dictatorship and bloody civil wars in the period 1996-2002. These conflicts, which took approximately 4 million human lives, are called "The First African World War". Elections were held but they did not guarantee the end of trouble for the divided and tormented people in the northeast of Congo, the real scene of bloodshed. The area is still turbulent because it abounds in mineral wealth - gold, diamonds and raw materials for nuclear technology. For a whole decade, unscrupulous actors of the African crisis were fighting there, for illegal profits (achievable in the chaos of bloodshed) rather than for democracy, defense of tribal interests, security, etc. as they claimed. In the mines of Eastern Congo unprecedented exploitation of people is still going on, especially of children, victims of conflicts, who suffer in great numbers from violence, starvation and diseases. These slaves of the crisis make local "warlords" and their mentors rich. The looting of the mines has stabilized the crisis because it makes possible enormous accumulation of wealth among armed decision-makers - which also includes availability of countless slaves-miners who have lost everything except their bare lives. Eastern Congo is, however, one of world?s three old focuses of plague; wild exploitation of ores in the area of this endemic disease has activated a sleepy focus and added pneumonic plague to the burdens suffered by the population of the rich but ill-fated region. This was to be expected because endemic plague in the gold-bearing evil circumstances impedes safe mining - and this will be the crucial challenge in the future of Congo. This article is an anthropological outline of the area where gold, plague, weapons and incomparable suffering of people merge together just because of cynic greed producing abuse and death, including the plague.
Organizations and national culture
Authors: Mojic Dusan
Published: July 2008

The paper deals with the most important contributions in studying cultural influences on organizations. The interest of social scientists in this topic began in the 1960s, based on the belief that it was necessary to overcome the dominant parochialism of US researchers in organizational theory and practice. Increasing internationalization of business activities, especially in the 1970s, imposed the need for large-scale studies and for finding practical solutions to the completely new problems encountered by multicultural organizations whose number was constantly rising. In spite of numerous and serious difficulties in every cross-cultural organizational study, several decades of development in this field have produced important theoretical and empirical contributions, enabling further advances in this scientific and practical discipline.
Eugenics as ideological component of fascism in Serbia in the 1930s
Authors: Malovic Ilija
Published: July 2008

The article presents an overview of racist ideas publicized in the nationalistic journal Ideas, the organ of the extreme right in Serbia in the 1930s. Inspired by the theories of inferior and superior races and nations very popular at the time, some intellectuals in Serbia tried to prove the Aryan origin of Serbs and Yugoslavs, but also to suggest how "racial hygiene" and "people's health" might be preserved. The article discusses especially the historical and social context in which such reactionary theories emerged, as well as the influence of leading racist ideologists from Fascist Italy and Nazi Germany on conservative intellectuals in Serbia.
Value goals as factors of youth political attitudes and opinions
Authors: Kuzmanovic Bora , Petrovic Nebojsa
Published: July 2008

The paper aims at establishing the relation between the degree of acceptance and preferences of relatively general personal and social goals (18 of each) and attitudes toward a set of politically relevant issues. The sample consisted of 243 18-year-old high school students. The resulting correlations between goals and attitudes are shown to be slight to moderate. Socially and politically relevant attitudes are connected more strongly with preferred social than personal goals. Two opposite groups of values (goals) have been found - conditionally speaking, modernism and traditionalism. They correlate positively or negatively with a number of attitudes, social identifications, trust in institutions and readiness for activism. This tendency has been confirmed by canonical correlation analysis.
An image of multiculturalism in Vojvodina: Language as a condition for communication
Authors: Pusic Ljubinko
Published: July 2008

The paper presents summarized results of a part of the research entitled "Sociological Aspects of Multiculturalism and Regionalization and Their Influence on the Development of the Autonomous Province of Vojvodina and the Republic of Serbia." The fact that Vojvodina represents a distinctly multicultural region necessitated further research of the following two questions: Do the inhabitants of Vojvodina speak some of the minority languages (apart from their native languages)? Should the people belonging to the majority nation learn a minority language, if they live in the surroundings where the respective minority constitutes the majority? The research data points to the conclusion that there is an unstable social basis for sustainable multiculturalism.
Welfare state: Evolution of an idea
Authors: Perisic Natalija
Published: July 2008

Originating from the so-called 'care of the poor', with substantially modified functions in later periods (which in turn determined its scope), the contemporary welfare state is currently at a crossroads, after the profound influence it exerted on the transformation of 20th century capitalism. Changes in conditions and circumstances in which it operates, in resources at its disposal, and in social forces defending it raise a number of questions regarding its survival. This in turn has consequences on the (achieved and future) level of social security of the population, and on the humanization of their living and working conditions. The emancipator potential of the welfare state, from the perspective of pursuing the goals of social inclusion, derives from the view that difficulties people in society are facing are not problems to be solved just by the individual and his/her family but which also demand complementary involvement of the state.
Oxidoreductase in rats intoxicated with cadmium
Authors: Olariu Lucia , Lupea Alfa , Chisu Iuliana , Tulcan Camelia
Published: July 2008

There are a lot of literature data concerning the toxicity of cadmium on liver and kidney. The present work is concerning with the investigation of the effect of two plant extracts: Alloe and Allium sativum and an alcoholic Propolis extract on the behavior of the antioxidant systems. There were studied especially the activity of three enzymes: catalase, methaemoglobine reductase and superoxid dismutase consecutive an installed oxidative stress after cadmium administration in single doze. The changes which appear in the protection enzyme's activity are different in the red blood cells and in liver. The natural extracts had a different influence on the enzymes activity. The alcoholic propolis extract was more efficient on catalase and superoxid dismutase activities in comparison with the Allium sativum extract. The last one had an important role in the activity of superoxid dismutase.
Transferring of Sclerotinia resistance from wild into cultivated sunflower: Combining of conventional and laboratory techniques
Authors: Vasic Dragana , Taski Ksenija , Terzic Sreten , Kevresan Slavko , Skoric Dragan
Published: July 2008

Five populations of each H. molis, H. maximiliani, H. rigidus and H. tuberosus were screened for resistance to stem form of Sclerotinia. On the basis of the results obtained by screening, nine crosses of resistant populations with either other wild species populations or with cultivated sunflower were made. As in some crosses a small quantity of seed was produced and the seeds germinated poorly, modified tissue culture methods were used to enhance germination and produce clones of interesting plants. These methods were found to be efficient both for seed germination and plant production and multiplication.
Heterosis in crosses between wheat genotypes with different spike architecture
Authors: Kobiljski Borislav , Dencic Srbislav
Published: July 2008

In order to estimate hybrid vigor, wheat genotypes differing in spike architecture (normal, tetrastichon and branched) were crossed and the F1 and F2 generations analyzed for the number of fertile spikelets/spike, number of grains/spike and grain weight/spike. The parents used for crossing were Sava (normal spike), Forlani (normal spike), ZG T 171/1 (tetrastichon spike) and ZG 172 (branched spike). The F1 and F2 progenies, except those from the cross Sava x Forlani, had a lower number of fertile spikelets/spike compared with the better parent. In the crosses between genotypes with normal and branched spikes, the F1 and F2 progenies formed significantly fewer grains/spike. On the other hand, the F1 of the crosses between genotypes with normal and tetrastichon spike showed a significant level of heterosis with respect to the number of grains/spike, particularly the cross Forlani x ZG T 171/1. In regard to grain weight/spike, significant heterosis was detected in all crosses except Sava x ZG 172.
The crosses between genotypes with normal and tetrastichon spikes that exhibited significant heterosis for two main yield components were most promising in the context of hybrid wheat development. Such crosses deserve further attention and investigation.

Authors: Krstic Borivoj , Boza Pal , Merkulov Ljiljana , Krstic Lana , Pajevic Slobodanka , Stankovic Zivko
Published: July 2008

The Lathyrus species are wild relatives of cultivated peas. Results of morphological, anatomical and physiological analyses of Lathyrus latifolius L. are presented in this paper. Certain measured parameters and observed morphological characteristics are not in agreement with available literature data, whereas no reference to the winged stem width, length of inflorescence pedicle, calyx length and leaflet index can be found. Two forms, f rotundifolium RCHB and f. latifolius BECK have been determined. Leaflets are amphystomatic, with anisocytic stomata present in almost equal number on both epidermises, dorsoventral, with one-layered palisade and many-layered spongy tissue. Stem in transverse section is rotund to oval with two long lateral wing-like expansions and cortical bundles. Mineral element analysis shows that the highest N, P and K concentrations were obtained with the flower while Ca and Na with the leaf. Leaf pigment content was higher than stem content while net photosynthesis rate was twice as high as respiration rate.
Molecular characterization of glutenin alleles at the Glu-Dl locus
Authors: Vapa Ljiljana , Obreht Dragana , Kobiljski Borislav , Davidovic Mihajla
Published: July 2008

It is well known that the composition of high-molecular-weight (HMW) glutenin subunits impacts the bread making quality. The HMW subunits 1Dx5-1Dyl0 are typically associated with high dough strength and good bread making quality contrary to 1Dx2-lDyl2 subunits. Bread wheat cultivars from Institute of Field and Vegetable Crops in Novi Sad have been screened for the alleles present at Glu-Dl locus using traditional SDS PAG electrophoresis method and a new PCR based approach. The Glu-Dl locus was screened for two main x-type alleles which code for HMW glutenins 2 and 5, and two main y-type alleles which code for HMW glutenin subunits 10 and 12. Among the analyzed cultivars 55.6% expressed the presence of 1Dx5 and 1Dy10 alleles at the Glu-Dl locus. These results confirmed that by using marker-assisted selection (MAS) it is possible to identify genotypes with alleles for good bread making quality which could be successfully used in wheat breeding programs.
A contribution to the study of stand degradation process on the territory of Fruska Gora National Park
Authors: Bobinac Martin
Published: July 2008

We analyzed the process of stand degradation of individual forest ecosystems in the region of the zonal community Tilio-Carpino-Qurcetum robori-cerris Jov. 79 located in the western part of Fruska Gora National Park. Degradation occurred is consequence to regeneration felling and it progressed towards the extinction of oaks, first of all the valuable pedunculate oak and Vergilius's oak, and then also Turkey oak. The analyzed mature stands were degraded coppice and mainly predominated by the Turkey oak in the tree stratum. In juvenile stands, often initially well regenerated with Turkey oak, the dominant species in the tree stratum are lime, hornbeam, flowering ash, field maple and other secondary species, predominantly of coppice origin. Restitution of the degraded stands is possible by applying an adequate regeneration system. Taking into account the primarily protective function of the analyzed forest ecosystems and the fact that these are degraded and coppice stands, the system of regeneration should be based on combined restoration.

Authors: Nikolic Zorica , Zlokolica Marija , Milosevic Mirjana , Vujakovic Milka
Published: July 2008

A study has been conducted in order to assess genetic variability in three maize populations, which are part of breeding material of Institute of Field and Vegetable Crops in Novi Sad. Variability has been analyzed for seven enzymes. PGM enzyme was monomorphic while enzymes ACP, GLU, IDH, MDH, PHI and PGD had from 2 to 5 alleles. In the total sample which consisted of 228 lines, 34 alleles were found. The greatest variability was found in Pgd1 and Pgd2. The average heterozygosities of loci per population were from 0.203 to 0.274, and polymorphism varied between 0.727 and 0.818. The genetic distances and heterozigosities among the populations marked them as suitable material for selecting parental pairs in development of maize hybrids.

Authors: Radenovic Cedomir , Hojka Zdravko , Selakovic Dragojlo , Misovic Miroljub , Pavlov Milovan , Secanski Mile
Published: July 2008

A hypothesis that elite erect leaf maize inbred lines are characterized by properties of an efficient photo-model and that as such are very desirable in increasing the number of plants per unit area (plant density) in the process of seed production has been confirmed in the present study. The properties of the observed elite erect leaf maize inbred lines were based on the effects and characteristics of thermal processes of delayed chlorophyll fluorescence occurring in their thylakoid membranes. The temperature dependence of the delayed chlorophyll fluorescence intensity, the Arrhenius plot for the determination of phase transitions (critical temperatures) and activation energy are the principal parameters of the thermal processes. Based on the obtained results on photosynthetic properties it was also possible to estimate the tolerance and adaptation of elite erect leaf maize inbred lines to high temperatures and drought.
Study of sugarbeet genotype response to nitrogen nutrition using leaf analysis
Authors: Petrovic Novica , Marinkovic Branko , Kastori Rudolf
Published: July 2008

Nitrogen rates and NPK ratios applied in the study had different effects on total nitrogen and nitrate contents in the laminas and petioles of the studied sugarbeet genotypes. Amount of nitrates, especially in the petioles can be considered the most reliable indicator for determining sugarbeet plant supply with nitrogen. Differences in nitrate content found among the genotypes indicate the necessity of knowing the genetic specificity in nitrogen nutrition for individual genotypes.

Published: July 2008

Hoverflies are well-investigated insects group on Obedska bara Marsh due to long-term investigations carried out by a scientific team from Faculty of Sciences, University of Novi Sad, Serbia (Vujic et al., 1998). After 15 years, monitoring of biodiversity in this Ramsar site is continued by scientific project 1770 of Ministry of Science and Environmental Protection Republic of Serbia. Based on new investigations and current nomenclature changes, the following results were obtained: record of Eupeodes goeldlini Maz?nek, L?ska et Bicik, 1999 is the first for Serbia, nine species were recorded for the first time for Obedska bara Marsh, seven species were replaced by recently established junior synonyms and three were excluded from the faunal list of Obedska bara Marsh. These data complete the list of 93 hoverfly species registered on Obedska bara Marsh.
Ornithologycal impotrance of Gruza accumulation
Authors: Barjaktarov Daliborka
Published: July 2008

Damming the middle part of Gruza River, in order to supply drinking and technical water for Kragujevac District caused appearance of Gruzanska accumulation. This lake fills the depression of Knicko Polje between the Gledicke Mts and Kotlenik. As the ornithofauna of accumulation lakes, both in this country and abroad, is poorly studied, this paper presents the data on the state of ornithofauna of Gruzansko Lake. The lake has an important role in migration of both native and foreign bird populations, but also as a wintering area for certain species of ducks and geese, as it is situated on the assumed Morava -Vardar migration route. During the research, 78 bird species were recorded and for 25 species it was proven that they breed in the area. Most species were recorded in the zone of strong anthropogenic influence, which is understandable as before the building of the dam and the artificial lake the Knicko Polje was dominated by agricultural land, mowed meadows and orchards.
Presence of Campylobacter spp. in nature
Authors: Stojanov Igor , Velhner Maja , Orlic Dusan
Published: July 2008

Presence of bacteria from Campylobacter spp. in nature and their importance encourages many researchers to study their biology. The aim of this study was to understand the epizootiology of these bacteria by analyzing all available data and our own results. This would help to follow their movements and prognosticate the outbreak of the disease caused by Campylobacter. In this experiment we used parts of the digestive tracts and reproductive organs of poultry and intestines of pigs and cattle. Isolation methodology was adjusted to the conditions favorable for Campylobacter spp. by providing selective mediums and microaerophilic conditions. Final determination of the isolates was done with Api Campy strips and appropriate software. Of the 60 samples analyzed, 42 were positive for the presence of Campylobacter spp. Campylobacter jejuni in 28 and Campylobacter coli in 14 cases. After examining samples from the reproductive tract, 4 birds were positive, with Campylobacter jejuni in 3 and Campylobacter coli in 1 sample. Of the 12 samples from pigs, 7 were positive (Campylobacter jejuni). Of the 6 samples from calves, Campylobacter jejuni was present in 4 cases. For the sake of clarity, the overall epizootiological situation, established on the basis of literature data and the obtained results, may be viewed as consisting of three interactive parts. The first one is the territorial prevalence of Campylobacter spp. The second is their presence in different kinds of animal and their systems (organs), and the third are health problems that occur in consequence to their presence.
The soil proteolytic activity and organic production of corn under the conditions of applying different nutrition systems
Authors: Mandic Leka , Djukic Dragutin , Stevovic Vladeta
Published: July 2008

The effects of increasing amounts of mineral nitrogen (90, 120, 150 kg?ha-1) liquid (80 t?ha-1) and solid manure (45 t?ha-1) those of inoculation with Azotobacter chroococcum (the strain 84) on the soil proteolytic activity and corn yield grown in monoculture were surveyed over the 3-year-long research work. The research results indicated that proteolytic activity and corn yield depended highly on the fertiliser sorts, amounts and on the research year too. Over the first research year, the highest proteolytic activity was recorded on the variants with organic fertilisers, whereas the fertiliser stimulating effect markedly decreased, particularly with liquid manure over the following two years of the research. Mineral fertilisers were also found to remarkably stimulate the biological parameters we have been concerned above, particularly the mean N amount (120 kg ? ha-1). While the highest corn yield could be obtained using 120 kg N ? ha-1 throughout all the research years, its insignificant rise and barely altered soil proteolytic activity using corn seed inoculation with 84 Azotobacter chroococcum could be noticed.
Biotic indices to be used for assessment of Ichthyofauna structure of the Zapadna Morava river (West Serbia, the Danube basin)
Authors: Markovic Goran , Veljovic Predrag
Published: July 2008

The presence of 25 fish species from 8 families was found to exist in the ichthyofauna of the Zapadna Morava river (the Danube basin, West Serbia) in the period from 1996-1999. The structure of the fish community was analysed using a substantial number of indices (Shannon's index - diversity Margalef's index of diversity, Sorensen's index of biotic similarity and Saprobic index of community). Qualitative-quantitative relationships in the ichthyofauna of the 4 river and one lake profiles were compared, too. High differences due to diversity in the general environmental conditions existing in the individual habitats were also established. An excessively high antropogenous impact on the diversity of aquatic ecosystems gave rise not only to a deteriorated water quality, but also to an abundance of the allochthonous ichthyofauna representatives.

Published: July 2008

Yellow pheasant?s Eye is a herbaceous plant from dry ressy areas. Owing to habitat destruction and over- collection for ornamental and medical purposes A. vernalis L. has became scarce in central and south Europe. The reasons for A. vernalis threatened are manyfold. The low seeds germination rate is significant. According to our investigation the main cause of fruit destruction is fungal infection. From the surface of the fruits, collected in Deliblato Sands, the following micromycetes has been isolated and determinated: Fusarium solani (Mart) Sacc., Fusarium sporotrichioides Sherb., Alternaria sp. and Drechslera sp. Histologycal analysis showed the presence of conidiomata and conidia Phoma sp. in the seeds.
Useful adaptive effect as a physiological process in functional systems of the organism
Authors: Zuravljev Vasiljevic
Published: July 2008

In the present work physiological principles and processes have been considered with respect to the theory of functional systems developed by Academician P. K. Anokhin. The elaboration of these principles, as well as the results of previous experiments, allowed us to propose a new notion of useful adaptive result. The adaptive effect is considered as a physiological process in the central nervous system, which results from reverse afferentation concerning the characteristic of an external object to neurons in the result- accepting apparatus. New notions of the useful effect (regulation of blood pressure, feeding behavior and human social activity) were evidenced by logical and experimental data. We reviewed the neurophysiological processes that accompany goal-directed activity of animals and underlie the formation of useful adaptive result in the system.
Isolation of Pasteurella multocida subspec. Multocida from chronic periapical lesion: First isolation in ex-Yugoslavia)
Authors: Suvajdzic Ljiljana , Mrdja Ekaterina , Dzambas Ljubomir , Bogavac Mirjana
Published: July 2008

This study presents five isolates of Pasteurella multocida subsp. multo-cida isolated from chronic periapical inflammatory lesion. We described the methods of sampling and cultivation as well as diagnostic criteria. Pasteurella multocida was diagnosed on the basis of characteristic cultural and tinctorial properties and the facts that all strains produced indole and induced ornithine decarboxilation, glucose, saccharose and manitole fermentation. Isolates produced neither urease, nor fermented lactose and maltose. Further classification to subspecies multocida was based on the fact that all investigated isolates fermented trechalose, xylose and sorbitol the traits which are diagnostically significant for the species. Patients deny any contact with farm animals or pets, which indicates a possible aerosol transport and animal-human as well as human-human infection. We consider that this organism should be paid more attention by dentist, oral surgeons and microbiologists.
Urticaria caused by Arcanobacterium haemolyticum: Diagnostic and therapeutic failures
Authors: Suvajdzic Ljiljana , Mrdja Ekaterina , Bogavac Mirjana , Dzambas Ljubomir
Published: July 2008

We presented a case of seventeen-year-old girl exhibiting mild symptoms of sore throat, a marked urticarial rash and heavy desquamations of the skin on palms and soles. According to the antibiogram and diagnosis of Streptococcus non A non B group obtained in routine laboratory procedure, the patient was treated with penicillin; however, ineffectively. Escalation of urticaria and failure of the initial penicillin therapy shifted the diagnosis towards exanthema toxoalergicum and thus to treatment with corticosteroids and antihistamines, yet with no improvement. The culture was repeated with a new specimen. Diagnosis was made according to the specific pattern in a double CAMP test, and confirmed by the ApiCoryne diagnostic set (BioMerieux). With respect to cultural traits, the isolate mimicked Streptococcus pyogenes, yet developing specific pattern in a double CAMP test that directed our diagnosis towards coryneform microorganisms. The diagnosis of Arcanobacterium haemolyticum was confirmed with 99.9% probability rate and T = 0.75.

Evaluating public participation geographic information systems (PP GIS) is essential to make improvements and generate standard practices for future projects, but it is probably the most neglected activity of the PP GIS development cycle. This research makes a contribution to the scarce information available about the usefulness of these systems in planning practice. The research examined the use of the PP GIS which was developed during last five years under the sponsorship of the Dutch Ministry of Spatial Planning, Social Housing and Environment, called "The New Map of the Netherlands".
The role of phosphorus in eutrophication
Authors: Bogdanovic Darinka
Published: July 2008

Eutrophication is an increase in the biological productivity of water basins resulting from the accumulation of biogenic elements under the influence of anthropogenic factors. Natural eutrophication is a slow and inevitable process. Artifical eutrophica-tion is caused by human activity and it can be very rapid, especially in technologically developed countries. Eutrophication does not represent a mere change of water but a change in the metabolism of the entire ecosystem and hence a change of the ecosystem itself. In Serbia and Montenegro, all factors are present that promote eutrophication in both still (especially in lowland areas) and running waters. This paper deals with the results of eutrophication monitoring and prognostication for the DTD canal network and major rivers and lakes in Serbia, including a special review of the trophic status of lakes in the country's main lowland region, the Vojvodina Province. As phosphorus concentration is an important factor in the process of eutrophication of a body of water, the study has devoted particular attention to the control of this element.
Variability of leaf characteristics in different pedunculate oak genotypes (Ouercus robur L)
Authors: Nikolic Natasa , Krstic Borivoj , Pajevic Slobodanka , Orlovic Sasa
Published: July 2008

The objective of this study was to determine genotype influences on pedunculate oak's leaf traits: leaf area, specific leaf area (leaf area per unit of leaf mass), concentration of photosynthetic pigments, rates of photosynthesis and respiration, and nutrient concentrations (nitrogen phosphorus, potassium, calcium, and sodium). Leaf samples were taken from seventeen Q. robur genotypes originating from clonal seed orchard Banov Brod (Srem, Vojvodina, Serbia). Leaf area of the studied genotypes ranged from 248.4 to 628.8 cm2, SLA from 109.4 to 160.7 cm2 dry matter-1, rates of photosynthesis and respiration from 6.98 to 20.32 and from 6.73 to 14.65 ?mol O2 m-2 s-1, respectively. The leaves of genotype 35 contained the highest concentration of photosynthetic pigments, while the lowest were recorded in genotype 29. The following pattern of nutrient concentrations was obtained for the studied genotypes: N>Ca>K>P>Na. Genotype variability of P K, Ca, and Na concentrations was more pronounced when compared with nitrogen. Estimated quantitative differences are the consequence of interaction of certain genotype and common environmental conditions for all trees. These results will provide information on intraspecific variation of the studied leaf characteristics.
Dynamics of dry matter synthesis during corn development
Authors: Latkovic Dragana , Starcevic Ljubinko , Marinkovic Branko
Published: July 2008

Effects of mineral nutrition and combinations of mineral and organic nutrients on the dynamics of vegetative mass development in corn have been examined in a long-term stationary trial. The dynamics was monitored per phenological stage and per plant part. The obtained results showed that the dynamics of dry matter accumulation changed in dependence of development stage and nutrition variant. Smallest gains in dry matter in all stages under study were obtained in the control variant. Highest gains were obtained in the variants which combined mineral nutrition and manuring. The smallest gain of dry matter, 7.22% of the dry matter accumulated at full maturity, was registered at the seven-leaf stage.

Published: July 2008

The biochemical marker phaseolin and isozymes were used in this work to display the variation of common bean germ plasma. Fifteen bean genotypes of different origin i. e. selections were studied. From 8 analyzed enzymic systems, enzymes MDH, SKDH, ME and IDH were polymorphic, while there were no differences in zymograms for enzymes PGM, PHI, PGD, and ADH. Analysis of phaseolin revealed two types: S and T. The S type of phaseolin was found in most of analyzed genotypes (9). Phaseolin type T was found in varieties of Novi Sad selection: Zlatko, Sremac and Aster, domestic population Zuto-zeleni Stepanovicevo and Jovandeka, Croatian variety Slavonski zuto-zeleni. Those varieties were developed from domestic populations from north-west region of Balkan, Slavonia, and Vojvodina.

The F2 progenies from crosses of wheat varieties Pliska, Sreca, Vila, Holly, three BM lines as Lr 26, Lr 34 and Lr 38 near isogenic lines (NIL), were tested simultaneously in the greenhouse at seedling stage (20?C) and differentiated according to the reaction type to Puccinia triticina monopustule isolate collected from Pesma, the most resistant wide grown variety in Serbia. The presence of Lr 26 and Lr 26 + Lr 34 genes was found in incomplete but not in partially resistant varieties Sreca and Vila. Pliska and three BM lines had a complete resistance controlled by other genes. Genes from Pliska acted complementary in authentic cytoplasm and were single effective in Lr 34 NIL (Thatcher background) one. Resistance of two BM lines was dependent of one gene. Lr 26 and Lr 34 had influence on resistance enhancement in the F2 of crosses with Sreca and Vila when NILs were donors of cytoplasm. They also increased frequency of completely resistant plants in progenies of Pliska. Resistance suppression controlled by gene linked with Lr 34 on 7D chromosome was evident.
Etiopathogenetic consideration and definition of the clinical manifestation of erosive dental defects
Authors: Stojsin Ivana , Blagojevic Duska
Published: July 2008

Dental defects of erosive nature are defined as irreversible losses of dental tissue, caused by long lasting and repeated action of acids that dissolve top layer of hydroxyapatite and fluorideapatites crystal structure, under assumption that aggressive factor is not of bacterial nature. Acids that cause changes on teeth according to their origin are gastric, dietetic, or they are of environmental origin. Current way of life, as well as nutritional habits create potentially dangerous conditions for the hard dental tissue, for prevention of mineralization process causes defects of oral system homeostasis. Defects occur on primary teeth, as well as on permanent teeth. However, this happens once and a half time more frequently on primary teeth due to the weaker primary maturation. In initial phases, changes are localized in enamel and by their development the bottom locates in dentine. Defects appear as smooth, shiny, round concavities on caries immune positions, or as cupping of occlusal surfaces. The depth of an eroded lesion consists of the depth of the crater plus the depth of tissue demineralization at the base of the lesion. Early verification of the etiological factor, together with good knowledge of the manifested shape change has influence to the prevention of the crown of tooth loss, complete occlusion, mastication and speech.

During the year 2006, climatic conditions were favourable for the appearance of head blight in the majority of localities in which wheat was grown in our country. In the locality of Apatin, in certain plots, the amount of detected infection was up to 25 infected heads per m2. During the harvest, heads with distinct disease symptoms and sporulation of Fusarium graminearum fungi were gathered. Grains from the parts of heads with manifested disease symptoms were separated into separate samples, together with the grains above and below the infested head part. Apart from ocular evaluation, the percentage of grain infestation by Fusarium genus fungi was determined in all three sample categories, using wet chamber method. Deoxynivalenol (DON) was determined in the samples after extraction, using acetonitrile-water (84:16 v/v) solution. Quantitative amount of DON was determined using liquid chromatography with DAD detector at 220 nm. The content of DON in the samples was as follows: grains with manifested disease symptoms 353,4 ppm (?g/g), grains above the infested head part 0,225 ppm (?g/g), grains below the infested part 0,125 ppm (?g/g). The content of zearalenone in the samples was determined using thin layer chromatography method. This toxic agent was determined only in the samples taken from the head part in which disease symptoms were clearly manifested in the amount of 2,1 ppm (?g/g).

HACCP (Hazard Analysis and Critical Control Point) is a concept which identifies, evaluates, and controls hazards, significant for food safety. It is applicable to the entire food chain, "from farm to table". Prevention of a food borne mycotoxin contamination of commodities is the most rational and cost-effective method for preventing adverse effects of fungal metabolites on human and animal health. Deoxynivalenol (DON) belongs to the group of mycotoxins produced by certain Fusarium species, which can damage several vital organs, or demonstrate immunotoxic effect, when ingested in small amounts for a longer period of time. Of particular concern is exposure of children to this mycotoxin through cereals, which are believed to lead to reduced weight gain and decreased liver weights. For that reason, we tried to present HACCP concept for preventing wheat contamination with deoxynivalenol. To be able to apply this system, hazards must be identified and risks assessed, and for that purpose a real picture of area (region) in which preventive measures shall be applied, need to be established. According to the results of the study conducted in the laboratory at our department, DON contaminated wheat samples in the region of Vojvodina accounted for 41,6% in 2004 and 2005, whereas amounts of deoxynivalenol ranged from 57 to 1840 ?g/kg.

A total of 88 and 40 wheat samples collected immediately prior to harvest in 2005 and 2006, respectively, under different agroecological conditions, were studied in respect to the occurrence of Fusarium spp. and the production of fusariotoxins. The greatest number of samples was infected with species of the genera Fusarium (81.8 and 65.0%), and Alternaria (36.3 and 17.5%) with the intensity ranging from 9.4 to 84.0% in 2005 and from 23.4 to 80.6% in 2006. Out of 13 identified species belonging to the genus Fusarium, F. graminearum had the highest frequency (35.2 and 12.5%) and the intensity up to 67.2%, and 21.9%, in 2005 and 2006, respectively, followed by F. poae but only in 2005 (20.4%), and F. proliferatum in 2006 (19.7%). The natural occurrence of mycotoxins in positive samples varied from 37 to 331 ppb for zearalenone and from 31 to 125 ppb for diacetoxyscirpenol (DAS) and T-2 toxin. The concentration of mycotoxins amounted, on average, to 133.4, 61.0 and 45.7 ppb for zearelenone, DAS and T-2 toxin, respectively.

The antifungal activity of Nepeta rtanjensis Diklic et Milojevic essential oil on mycelia growth has been performed by macrodilution method. The most efficient impact of N. rtanjensis essential oil on mycelia growth in vitro was found in Alternaria species with the same value of minimal inhibitory quantity (MIQ) of 0.6 ?l/ml. Bipolaris spicifera and Cladosporium cladosporoioides had MIQ values of 1.0 ?l/ml whereas Trichoderma viride with MIQ value of 1.6 ?l/ml showed the most efficient defense against the essential oil examined. The values of minimal fungicidal quantity (MFQ) in Alternaria sp. 2, B. spicifera and C. cladosporioides match the MIQ values whereas MFQ values in Alternaria sp. 1 is 0.8 ?l/ml, and in T. viride 1.8 ?l/ml.

Marshmallow is an important medicinal plant in Serbia. Because of increasing demands on the market, cultivation has been started. Through regular quality control of commercial seeds and plantations, mycopopulation of marshmallow was recorded in the period 2000-2006. Seeds of marshmallow were dominated by Alternaria alternata and species from the genus Fusarium (Fusarium verticillioides, F. proliferatum, F. semitectum, F. oxysporum and F. solani). Species belonging to Fusarium genus are the cause of rot of seeds and roots of marshmallow, causing chlorosis and fading, and therefore deterioration and necrosis of plants, as well as decrease of seed germination of seeds. Leaves and stalks of marshmallow were from time to time under massive attack of Puccinia malvacearum, and that was the reason why leaves were unuseful as a herbal drug. On roots and lower part of the stalks, massive appearance of Sclerotinia sclerotiorum, a causal agent of the white rot, in cases when marshmallow was cultivated after sunflower, was recorded, too. From other fungi in roots, species belonging to the genus Fusarium (F. oxysporum, F. solani and F. verticillioides) were dominant.

Dogs are animals that are most often kept as pets in the cities. Their health problem may be the cause of infections of humans and animals. Skin changes and etiology factors present important segment of the diseases that disturb health of the pets. The objective of this work was mycology examination of scarifications and skin swabs from dogs with clinical symptoms. The aim was to find out which fungi species can be isolated from the changed parts of the skin, and whether is possible that, besides dermatophyte, saprophyte fungi from the environment may also be the cause of the changes, and to reveal their effect on the host. During a one year period, 67 swabs and scarifications from dogs were examined to detect the presence of fungi. The samples were streaked on Sabourdaud's dextrose agar and incubated for 10-21 days at 25?C. In microscopis examination according to their shape, and color, the colonies were identified as conidia, macroconidia and conidiaophora. From 59, of total 67 samples, the following saprophyte fungi were isolated: Aspergillus sp., Penicillium sp., Alternaria sp., Mucor sp. and Fusarium sp. Occurrence of these fungi means that a considerable increase of this microbiological flora may be expected in homes of the owners. This may be the cause of systemic mycosis and allergies in animals and humans, as well as a possibility of contaminated food and incidence of mycotoxicosis.
