Genetička divergentnost divljih populacija Mačijeg repa (Phleum pratense L.)

The collection consisted of 10 autochthonous populations of timothy, originated from eastern, western and south-eastern Serbia was investigated. Several morphological traits and dry matter yield were measured. Significant differences between populations were detected by analysis of variance of two-year results. The highest average within population variability was determined for the dry matter yield per plant (CV 85.08%). The highest variability was, also, determined for the number of tillers (CV 64.88%), while the lowest variability was determined for time of heading (CV 5.8%). The highest dry matter yield per plant was measured in the population of Crni Vrh, Rendara and Nerađe locality. Also, these populations had high average values for the other studied traits.Na kolekciji od 10 autohtonih populacija mačijeg repa poreklom iz istočne, zapadne i jugoistoične Srbije proučavane su morfološke osobine i produktivnost suve materije. Na osnovu dvogodišnjih rezultata analizom varijanse su utvrđene značajne razlike između ispitivanih populacija. Prosečno najveća unutarpopulacijska varijabilnost je zabeležena za prinos suve materije po biljci (85,08%). Visoka varijabilnost je zabeležena i za broj izdanaka po biljci (64,88%), dok je najmanje variranje utvrđeno za vreme klasanja (5,8%). Najveći prinos suve materije po biljci utvrđen je za populacije poreklom sa lokaliteta Crni Vrh, Rendara i Nerađe. One su takođe pokazale visoke prosečne vrednosti i za ostale ispitivane osobine

von Willebrand Factor and Oxidative Stress Parameters in Acute Coronary Syndromes

Considering the role of von Willebrand factor (vWf) in hemostasis, and the role of oxidative stress in the development of endothelial dysfunction and atherosclerotic disease, the aim of our study was to investigate the relationship between vWf, parameters of oxidative stress and different types of acute coronary syndromes (ACS). Levels of vWf activity (vWfAct), vWf antigen (vWfAg), nitric oxide (estimated through nitrites–NO2 −), superoxide anion radical (O2 −), hydrogen peroxide (H2O2), index of lipid peroxidation (estimated through thiobarbituric acid reactive substances–TBARS), superoxide dismutase (SOD) and catalase (CAT) activity of 115 patients were compared with those of 40 healthy controls. ACS patients had significantly higher vWfAct and vWfAg levels, as well as TBARS levels, while their levels of NO2 −, H2O2, SOD and CAT activities were lower than controls'. vWfAg showed high specificity and sensitivity as a test to reveal healthy or diseased subjects. Multivariant logistic regression marked only vWfAg and TBARS as parameters that were under independent effect of ACS type. The results of our study support the implementation of vWf in clinical rutine and into therapeutic targets, and suggest that ACS patients are in need of antioxidant supplementation to improve their impaired antioxidant defence

Stanje i problemi u proizvodnji kabaste stočne hrane u zapadnoj Srbiji

In order to improve forage production, through more efficient use of agricultural land, conducted a study of fertility and soil acidity, and the manner of its use in hilly and mountainous areas of the Municipality of Kosjerić. The largest number of sampled soil is acidic chemical reaction, very low the level of provision easily accessible phosphorus, which is a limiting factor in successful growing legume. Depending on the results and the production potential of the sampled area and the needs of local farmers, were applied technologies that will contribute to increased yield or biomass and changing botanical composition in terms of increased participation of legumes.U cilju unapređenja proizvodnje stočne hrane, kroz efikasnije korišćenje poljoprivrednog zemljišta, vršeno je ispitivanje plodnosti i kiselosti zemljišta, kao i načina njegovog korišćenja u brdskim i planinskim područjima Opštine Kosjerić. Najveći broj uzorkovanih zemljišta je kisele hemijske reakcije, veoma niske obezbeđenosti lako pristupačnim fosforom, što predstavlja ograničavajući faktor pre svega uspešnom gajenju leguminoznih biljnih vrsta. U zavisnosti od dobijenih rezultata i proizvodnog potencijala uzorkovanih zemljišta kao i potreba lokalnih farmera, primenjene su tehnologije koje će doprineti povećanju prinosa biomase ali i promeni botaničkog sastava u smislu povećanog učešća višegodišnjih krmnih leguminoza

Gamma angle, a measurement tool of the femoral head angular translation in adults hips with cam or mix form of impingement femoroacetabulare

Femoral head translation leads to the cam deformity development. It is formed on the femoral head-neck junction. Cam deformity produces femoroacetabular impingement. There are no particular techniques for femoral head translation assessment. The offset index is the most regularly applied. It quantifi es the relation between the femoral head and neck junction. We introduce the original method to test the femoral head translation. The purpose of this survey was to draw, measure and to test gamma angle rates. Tested groups were subjects with cam and mix form of femoroacetabular impingement. We compare gamma angle values with the offset index. Gamma angle role in femoral head angular inclination measurement, we considered.</p

Chromosomal diversity in Apis mellifera carnica from Serbia

Comparative chromosomal investigations of three honey bee ecotypes of A. m. carnica (the Banat, the Timok and the Syenichko–Peshterski ecotype) from Serbia were performed. G-band analyses revealed differences between Timok and Banat honey bee ecotypes in chromosomes 2, 4, 11 and 13. Between the Timok and Syenichko–Peshterski ecotypes, differences were observed for chromosomes 1, 12, 15 and 16. The greatest differences in G-band number and distribution were registered between the Syenichko–Peshterski and Banat ecotypes in chromosomes 1, 2, 4, 11, 12, 13, 15 and 16. The results point to great interecotype variability of G-band pattern of chromosomes of the carniolan honey bee in Serbia. To preserve such honey bee diversity in Serbia, the three investigated ecotypes require attention for conservation

Calibration System for Thermocouple Testing

One of activities of the Mining and Metallurgy Institute is production of thermocouple elements made of precious metals. Since this is a complex technological process and the quality control of produced elements is performed by other institutions, sometimes the whole series of products can happen to be bad and not useful. This is increasing costs and time of production, as well. To prevent wasting of time and money, the special measuring system is developed. The kernel of the system is already existing microprocessor measuring station - MMS. The MMS’s hardware configuration, initially designed for industrial process control requirements with suitable input channel characteristics and adequate response time is adapted for the purpose of thermocouple calibration. Appropriate software solution is developed, as well. This article describes the practical solution for thermocouple testing and calibration. Hardware interface, principles of system integration and developed software are also included
