?ivanovi? Sandra,NikoliSandra,Jevti? Milorad,Koci? Sanja
Medicinski Pregled , 2010, DOI: 10.2298/mpns1010668z
Abstract: Introduction. Knee osteoarthrosis is a degenerative disease which induces intense trouble. Material and methods. The aim of the study was the parallel analysis of clinical and ultrasound examination in patients diagnosed with knee osteoarthrosis. A group of 88 patients underwent the clinical examination and the outflow and size of flexion were determined, the intensity of pain was assessed by the patient's mark on VAS, the functional ability by HAQ index, and the size of effusion and synovitis by arthrosonography. Results. The minimal outflow was diagnosed in 34.1% of patients, medium in 22.7%, and significant in 4.5%. Synovitis was evident in 67% of patients, 17.0% had nodular, 30.7% diffuse and 19.3% nodular-diffuse type. Effusion was observed in 75% of patients. The average size of synovitis in suprapatellar recess (SR) in the patients with significant, medium and lateral outflow was 6.68 (2.93-10.04) mm (p=0.000), 1.57 (0-5.53) mm (p=0.006) and 6.18 (3.44-7.10) mm (p=0.000), respectively. The grade of pain on VAS was the highest in patients with significant outflow 70(60-95) (p=0.014), effusion 60 (50-80) (p=0.024) and nodular type of synovitis 70 (50-90) (p=0.029). There was a significant correlation on VAS in the positive direction with the size of effusion (r=0.238, p=0.025) and synovitis in LR (r=0.215, p=0.044), HAQ index (r=0.502, p=0.000), and in the negative direction with the size of flexion (r=-0.346, p=0.001). The average size of flexion in the patients with significant outflow was 90 (82.5-90)°(p=0.000), HAQ index 1.99 (1.49-2.30) (p=0.078). HAQ index depended on effusion in LR in the positive direction (p=0.014). Discussion and Conclusion. Clinically significant outflow is shown by arthrosonography as the biggest in SR, moderate and minimal only in LR. Moderate or significant outflow, effusion and nodular type of synovitis lead to intensive pain. Patients with bigger functional disability had intense pain, significant outflow in LR and significantly limited motions.

Abstract: Above-ground biomass production of three white clover cultivars with different origin (Jura, Regal and Rivendel ) was investigated on two soils with 5.61 and 6.27 pH values and at substrate with pH 7.56. Total above-ground biomass, leaf and stolon mass, leaf/stolon ratio and dry matter content of leaf and stolon were evaluated on 30 days old plants. Significant influence of soil was found for all investigated traits with exceptions of leaf/stolon ratio and dry matter content of stolon. On the cultivars average plant development was the best on the soil with pH 6.27, and worse at substrate. Cultivars significantly differed in all investigated traits with exception of leaf/stolon ratio trait. Cultivar Regal obtained the lowest values of most of the investigated traits. Cultivars Jura and Regal differed from each other in dry matter content of leaf

Abstract: Aggregatibacter actinomycetemcomitans is considered one of the bacterial species of etiological importance in periodontitis. The aim of this study was to evaluate the serotype of A. actinomycetemcomitans in the subgingival biofilm in subjects with periodontal health and disease. Pooled samples of subgingival plaque were taken for culture-based identification of microorganisms. Colonies suspected to be A. actinomycetemcomitans were selected for molecular identification using either multiplex or conventional PCR in serotype-specific genotyping and 16S rRNA gene sequencing. In silico analysis showed that most selected colonies belong to the genus Campylobacter, although positive signals for serotypes of A. actinomycetemcomitans were obtained with these samples. Identification of A. actinomycetemcomitans by conventional PCR for 16S rRNA with one species-specific and one universal primer was inconclusive because an almost identical signal with Campylobacter gracilis was obtained. Although PCR-based methods for the identification of A. actinomycetemcomitans are more rapid, sequencing should not be omitted.

Acta Periodica Technologica , 2005, DOI: 10.2298/apt0536091c
Abstract: Two new Mn(III) mixed-ligand complexes with two acetylacetonate (acac) ligands and one maleate ligand and its hydroxylamine derivative of the general formula [Mn(C5H7O2)2L] were prepared. Their structure was established by using elemental analysis, FTIR and UV/VIS spectroscopic methods, as well as magnetic measurement. Replacement of the acetylacetonate ligand by the corresponding acid ligand has been confirmed in Mn(III) acetylacetonate. Based on the obtained experimental data and literature indications, structural formulae to these compounds were assigned.

Journal of the Geographical Institute Jovan Cvijic, SASA , 2012, DOI: 10.2298/ijgi1202015n
Abstract: For an integral perception of the possibility of forecasting erosion-deposition processes and their consequences it is essential to analyze the factors of erosion and deposition. The attempt was made in the paper to analyze quantitative and qualitative impact of some of the most important factors of erosion-deposition processes. The analysis was performed through a multidisciplinary approach, on the example of the Zapadna Morava River upper basin. The methodology of research encompasses an application of the adequate knowledge from the areas of meteorology, geomorphology, hydrogeology, spatial planning, economic geography, forestry, hydrology and environmental protection. The analysis encompasses meteorological factors, terrain characteristics and anthropogenic factors. The importance of the analysis and forecasts of the investigated processes for the industry, economy, spatial planning and environmental protection was emphasized.
Ethno-cultural stereotypes in the function of local identities

Glasnik Etnografskog Instituta SANU , 2008, DOI: 10.2298/gei0801115n
Abstract: The paper discusses various problems in regional identities of ethnic and other groups in Serbia. According to the author, a forming and maintenance of local identities is under a heavy influence of stereotypes held by one group towards the other, neighboring groups, where ethno-demographic, historical and socioeconomic features also play the role. Cultural and character features of a group stand out as markers of the group homogeneity; these markers also serve to differentiate a group from another, while humor is cited as a primary way to express a stereotype. The author further discusses long lasting and slow changes in stereotyping, and argues that stereotypes could be overcome with a more even distribution of existential means along side better understanding of ethno-cultural characteristics of an ethnicity. The research in Serbia confirms inter-dependency of local identities and stereotypes; this, in turn, creates conditions for forming cultural types of population (in this case the Goranci and Era) which represent local cultures and carriers of local identities.

Economic Annals , 2004, DOI: 10.2298/eka0462191n
Abstract: In this paper we have calculated indexes of export-import similarity (Serbian exports and EU imports) by using certain statistical methods. A considerable increase in indexes of export-import similarity, after the approval of the EU preferential, shows that Serbian exports used to be adjusted to the EU market. After suddenly increasing, indexes of export-import similarity then decreased followed by a fall in the share of manufactured products in total exports, although the total exports and exports to the EU recorded a further increase. This fact clearly shows that a growth in exports was achieved mainly by primary products, which widened a gap between the Serbian export structure and that of the EU import structure. Therefore, a growth in Serbian exports can not be sustained without radical restructuring of the Serbian export sector.
Is there a structural improvement in the merchandise exports of the Balkan countries in the period 2000-2012?

Economic Annals , 2013, DOI: 10.2298/eka1396099n
Abstract: The value of indicators of the similarity of Balkan countries’ export and import structures to those of developed countries grew only mildly, which indicates that the unfavourable structure of exports has been retained. While similarity coefficients increased in the period until and including 2012, they failed to reach a critical turning point as in advanced European countries in transition. In practically all Balkan economies, since 2000 the technological intensity and the factor intensity of foreign trade have changed toward an increased share of highly-processed products, but the share of skill-intensive manufactures remained almost two times smaller than in developed economies. An aggravating factor was the continual strong double-digit growth of exports in most Balkan countries, which ‘ forced’ exports based on the existing inappropriate structure and prevented a change in export structure. Balkan countries would have to attract FDI in export sectors that are capital- or skilled labour- intensive. A targeted industrial policy and sector- and firm-level strategies are necessary to give momentum to a shift towards technology-intensive activities, associated with higher spillover effects. It is realistic to expect that the evolution of the economic system through restructuring would additionally improve the still unfavourable structural characteristics of Balkan countries’ exports.

Abstract: In four interspecies crossing combinations of grapevine (Seedling 108 x Muscat Hamburg, Muscat Hamburg x Seedling 108, S.V. 18315 x Muscat Hamburg and Muscat Hamburg x S.V. 12375) during three years period, important phenological phases (bud burst, blooming time, veraison and ripening time) were examined. Based on results of analysis of variance, for all investigated characteristics, components of variability, coefficients of genetic and phenotypic variation and coefficient of heritability in a broader sense were calculated. Values of these parameters depended a lot on examined crossing combination. In majority of all investigated characteristics and almost for ail crossing combinations, genetic variability took the biggest part in total variability. Only for blooming time, in crossing combinations Seedling 108 x Muscat Hamburg and Muscat Hamburg x S.V. 12375, year variability participated the most in total variability. The lowest coefficients of genetic and phenotypic variation were established for blooming time (4.01%; 4.86%), and the largest for veraison (36.43%; 38.81%). Considering examined crossing combination, coefficient of heritability was from 63.08% up to 70.76% for bud burst, from 60.61% up to 87.71% for blooming time, from 84.58% up to 88.14% for verasion and from 56.86% up to 89.29% for ripening time.

Abstract: Introduction. Forensic expertise has not specified with certainty any specific injury among fatally injured frontal car-occupants in frontal car collisions. Objective. To establish if blunt injuries of thoracic aorta, heart, and pericardium could be used as predictors where the fatally injured car-occupant was at the moment of car-collision. Methods. A retrospective autopsy study was performed. The subjects were fatally injured car-drivers, front-seat and rearseat passengers in head-on car collisions. In each of them we analyzed the injuries of thoracic aorta, heart and pericardium. Results. 492 subjects were analyzed (378 male and 104 female): 239 car-drivers, 194 front-seat and 49 rear-seat passengers. The isthmus of aorta was the commonest site of simple blunt rupture among car-drivers and front-seat passengers. Among more than half of the observed subject, there was aortic blunt rupture as concomitant injury with heart and pericardium injuries. Heart and pericardium ruptures were most common among fatally injured car-drivers. Most frequently injured part of the heart was the right atrium. Injuries of thoracic aorta, heart and pericardium indicated a higher probability that the fatally injured would be the car-driver (λ=0.818; df=2; p=0.011, λ=0.906; df=2; p=0.000, and λ=0.951; df=2; p=0.000); this was also pointed out by the rupture of the right atrium and multiple ruptures of the thoracic aorta (λ=0.966; df=2; p=0.000 and λ=0.918; df=2; p=0.009). The concomitant injuries of the thoracic aorta with thoracic spine, sternum and heart pointed out that the injured person was the car-driver (λ=0.971; df=4; p=0.007, λ=0.974; df=4; p=0.013 and λ=0.958; df=4; p=0.000), as well as the concomitant injuries of heart and sternal fracture (λ=0.960; df=4; p=0.001). The probability of about 80% that the fatally injured person in head-on collisions was a car-driver was pointed out by concomitant blunt thoracic aorta rupture with fractured sternum and ribs (Wald. coeff.=8.611; df=1; p=0.003, and Wald. coeff.=3.875; df=1; p=0.049). Conclusion. The basic mechanism of the injury of thoracic organs is deceleration, as well as anteroposterior compression with caudorostral hyperextension. That is why thoracic organ injuries are mostly concomitant. Fatally injured car-drivers suffered more often of these injuries than other car-occupants. The probability that the fatally injured was the car-driver rises with the number of concomitant injuries of thoracic aorta, heart and pericardium, as well as with the fractured thoracic-cage bones.
