    Investigation of physical properties of dense plasmas is one of the important topics in the physics of inertial confinement fusion, warm dense matter and high-power lasers physics. Due to the big difference between the mass of ions and electrons the considered plasma is dense and non-isothermal. It is known that the interaction potentials between particles are also of importance for correctly calculation of plasma properties taking into account peculiarities and parameters of investigated plasma [1]..

    The purpose of the research is to establish the species composition and contamination of saigas with the main helminths, as well as to determine the effectiveness of the supramolecular complex of albendazole with polyvinylpyrrolidone at helminthoses in the conditions of the West Kazakhstan region. Materials and methods. Incomplete helminthological autopsy according to K. I. Skryabin was used to study the contamination of saigas with helminths. Supramolecular complex of albendazole with polyvinylpyrrolidone was tested on 30 saigas spontaneously infected with gastrointestinal strongylates and Moniezia spp. Animals of different groups of 10 animals each were administered orally the supramolecular complex of albendazole with polyvinylpyrrolidone at a single dose of 2.0 mg/kg of the AS compared with the base drug albendazole in a dose of 7.5 mg/kg of the AS. The control was a group of saigas that did not receive the drug. The effectiveness of the drugs was considered according to the data of coproovoscopic studies of saigas by the flotation method before and 14 days after administration. Results and discussion. The prevalence of saiga infection with Moniezia spp. in the West Kazakhstan region averaged 37%, Echinococcus sp. 25, Trychostrongilus spp. 62, Ostertagia spp. 87, Marshallagia sp. 87, Haemonchus sp. 75, Nematodirus spp. 87 and Trichocephalus spp. 25%. The 100 % efficiency of the supramolecular complex of albendazole with polyvinylpyrrolidone was obtained at strongylatosis of the gastrointestinal tract and monieziosis of saigas at a dose of 2.0 mg/kg of the AS according to the studies of fecal samples with 80–70% effectiveness of the base drug. ЦСль исслСдований: ΡƒΡΡ‚Π°Π½ΠΎΠ²ΠΈΡ‚ΡŒ Π²ΠΈΠ΄ΠΎΠ²ΠΎΠΉ состав ΠΈ ΡΡ‚Π΅ΠΏΠ΅Π½ΡŒ инвазированности сайгаков основными Π³Π΅Π»ΡŒΠΌΠΈΠ½Ρ‚Π°ΠΌΠΈ, Π° Ρ‚Π°ΠΊΠΆΠ΅ ΠΎΠΏΡ€Π΅Π΄Π΅Π»ΠΈΡ‚ΡŒ ΡΡ„Ρ„Π΅ΠΊΡ‚ΠΈΠ²Π½ΠΎΡΡ‚ΡŒ супрамолСкулярного комплСкса Π°Π»Π±Π΅Π½Π΄Π°Π·ΠΎΠ»Π° с ΠΏΠΎΠ»ΠΈΠ²ΠΈΠ½ΠΈΠ»ΠΏΠΈΡ€Ρ€ΠΎΠ»ΠΈΠ΄ΠΎΠ½ΠΎΠΌ ΠΏΡ€ΠΈ Π³Π΅Π»ΡŒΠΌΠΈΠ½Ρ‚ΠΎΠ·Π°Ρ… Π² условиях Π—Π°ΠΏΠ°Π΄Π½ΠΎ-ΠšΠ°Π·Π°Ρ…ΡΡ‚Π°Π½ΡΠΊΠΎΠΉ области.

    The purpose of the research is to identify the law of cattle infection by main helminth species in West Kazakhstan region depending on environmental conditions.Materials and methods. Fullebourn’s method of flotation was used to study helminths infection of cattle. Calculation of the number of helminth eggs and larvae in 1 g of feces was conducted with the help of count chamber VIGIS. Strongylata identification up to generation was conducted according to P. F. Polyakov after larvae cultivation according to N. A. Akulin based on the morphological structure of infective strongylata larvae parasitizing in cattle. Thelazia was washed out from conjunctival eye sac by 3% boric acid solution. Parenchymal organs (hepar, lungs) were tested on detection of caseworm cysts. The researches were conducted once every three months to study helminths seasonal dynamics.Results and discussion. Maximum precipitation in steppe and semi-desert zones is observed in spring 24.2 and 18.7 mm and in autumn 33.0 and 28.0 mm, and minimum precipitation is observed in summer 9.2 and 8.5 mm respectively. Maximum precipitation in desert zone is suited on winter (14.4 mm) and at autumn (14.0 mm). Cattle prevalence by main helminths species in steppe, semi-desert and desert zones of West Kazakhstan region was the lowest in winter and the largest in autumn. In steppe zone the degree of infection by digestive tract strongylata was 27.6 and 44.3%, by moniezia 17.9 and 19.1%, by thelazia 3.2 and 86.9% respectively. In winter and in autumn in semi-desert zone the degree of cattle infection by digestive tract strongylata was 14.4 and 33.8%, by moniezia 15.7 and 18.2%, by thelazia 2.2 and 79.3 % respectively. In winter and in autumn in desert zone the degree of cattle infection by digestive tract strongylata was 11.4 and 27.2%, by moniezia 14.8 and 15.3%, by thelazia 2.4 and 78.2% respectively. Prevalence by caseworms did not change essentially during the year and was in steppe, semi-desert and desert zones average 40.3%, 35.6% and 31.6% respectively.ЦСль исслСдований: ΠΎΠΏΡ€Π΅Π΄Π΅Π»ΠΈΡ‚ΡŒ Π·Π°ΠΊΠΎΠ½ΠΎΠΌΠ΅Ρ€Π½ΠΎΡΡ‚ΡŒ инвазированности ΠΊΡ€ΡƒΠΏΠ½ΠΎΠ³ΠΎ Ρ€ΠΎΠ³Π°Ρ‚ΠΎΠ³ΠΎ скота основными Π²ΠΈΠ΄Π°ΠΌΠΈ Π³Π΅Π»ΡŒΠΌΠΈΠ½Ρ‚ΠΎΠ² Π² Π—Π°ΠΏΠ°Π΄Π½ΠΎ-ΠšΠ°Π·Π°Ρ…ΡΡ‚Π°Π½ΡΠΊΠΎΠΉ области Π² зависимости ΠΎΡ‚ мСтСорологичСских условий.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    Trends in soil changes in the South-West of the Belgorod region

    No full text
    The analysis of the Landsat 5 satellite data helped to study the processes of soil changes which took place from 1991 to 2011 inclusively at the test site located in the south-west of the Belgorod Region. As a result, it was found that despite intensive agricultural land use the proportion of soils, the properties of which have changed over the past 20 years, within the total area studied is quite small. The changes of soil erosion status were recorded within the territory of no more than 1 % of the total area; the territories characterized by soil humus losses on subhorizontal surfaces cover no more than 2 % of considered area. The most intensive process among the others is humus accumulation in the soil, the increase in humus content is noted on 5.6 % of the analyzed area. The identified tendencies in soil changes may be due to both the specifics of agricultural land use and climate changes
