Реферат: An estimate of the ecological state of the springs\' outlets in West Kazakhstan is given in the article. The research results and the GPS-positioning of groundwater outlets are given in the article. The analyses of foreign research of the springs have been carried out. The results of hydro-chemical and toxicological examination of 30 springs in West Kazakhstan are given in the article. A comparison of the springs parameters have been made. An estimate of the spring water chemistry formation is given in the article. The paper describes the content of cations and anions, heavy metals, oil products in hydro-geochemical samples of spring water in comparison with the sanitary standards and requirements to water quality. In some springs the MPC exceedance of cadmium and chromium has been revealed. The estimation of spring waters contamination by nitrates and the influence of various factors on its level has been accomplished. It was established that the low nitrates concentrations in water, which do not exceed the MPC are peculiar for majority of the studied springs. The \"Risk factors\" for the occurrence of nitrates in water are the close allocation of agricultural landscapes and the location of springs on the slopes of draws. The influence of anthropogenic factor on the condition of spring areas of the West Kazakhstan has been assessed. Three groups of springs have been distinguished according to the fracturing level of their natural state and to the character of anthropogenic impact.

Реферат: The article prezents the results of clinical and pathomorphological study of 579 slaughtered and compulson slaughtered sheep in Almaty region. Pathomorphological study has revealed that echinococcosis of sheep mainly affects liver and lungs, other organs are rarely affected. In all cases in affected organs larval echinococcus has been a unilocular cyst filled with liguid and surrounded with two-lauer shell of significant sizes. In terms of histology a necrosis zone has been formed around the cyst, theh, a site of cellular infilration from eosinjphils, plasmatic cells, lymphocytes, macrophages and fibroblasts. Occasionally sites of accumulation of lymphoid elements have been observed, which form lymphatic nodes.

Реферат: The studies conducted have provided data enabling one to evaluate the productivity of feed crop in the frontier zone of the West Kazakhstan Provinct of the Republic of Kazakhstan and the Saratov region of the Russion Federation for the use innovative technologies on feed protein production. The studies have sacertained the feasibility of cultivation of sorghum, Sudan grass and milled agrophytoctnoses in the noted frontier zone instead of the conventional barley crops. Suggested croppers are distinguished by active protosynthetic activity. Over the 5-year period the average maximuza leaf area of sorg hum crop makes 52.0 thousand m/ha, crop of Sudan grass and coarse millet generat 46.0 and 42 thousand m/ha, respectively. And in the bearley crop does not excttd 23.6 thousand m /ha. Studied agrophytocenoses of annual forage crop differ fy yield og fodder units, digestible protein, feeding protein units (FPU) per unit og land, and the accumulation of the metabolic energy. Over 5-year study period, the highest yield of green mass was provided by sorghum and Sudan grass crop - 26.1 t/ha and 16.2 t/ha, respectively. Productivity of barley was significantly inferior to sorghum and Sudan grass, accounting for just 12.0 t/ha.
Ways of Increasing the Grain Crops Yield under the Farming Biologization
Реферат: In recent years the strengthening of anthropogenic impact onto an arable land, an unsysrematic use of land and lack of measures to preserve the fertility have led to the intensive soal degradation. In this regard, the preority direction was the increase of in plant gpowing productivity and quality of crops while preserving the soil fertility by the biological factors acrivating that do not violate the natural essenct and ecological balance of agroecosystems. With the comprehensive research we could find an influenct of organic fertilizers (animal manure, a straw, green manures) on the crop yields. In the conducted researhes we have studied the dependence of crop yield on the conditions of their moisture provision, agrophysical and agrochemical indices of the dark chestnut soil.

Реферат: The present researsh work shows the humus content change due to the longterm anthropogenic impact. In particular, there has been shown the humus content change under various soil treatments: plowing, flat- cutting treatment of 25-27 cm and 12-14 cm, and zero tillage. Involvement of the flat-cutting treatment (25-27 cm) in crop rotation has lead to a significant increase of humus content in soil layer of 0-40 cm in comparison with plowing on the same depth.
Diffraction of plane wave by strip with arbitrary orientation of wave vector
Реферат: The classical problem for diffraction of a plane wave with an arbitrarily oriented wave vector at a strip is considered asymptotically by Wiener-Hopf method. The boundary-value problem has been broken down into distinct Dirichlet and Neumann problems. Each of these boundary-value problems is consecutively solved by a reduction to a system of singular boundary integral equations and then to a system of Fredholm integral ones of second kind. They are solved effectively by a reduction to a system of linear algebraic equations with the help of the etalon integral and the saddle point method.

Фотокаталитическое разложение сероводорода из сероводородсодержащих нефтяных, попутных и отходящих газов
Реферат: Полученные данные свидетельствуют о том, что нанесенные на монтмориллонит Fe-, Ti- и W-катализаторы можно использовать для фотокаталитического разложения H[2]S при УФ и солнечном облучении в мягких условиях.
Пилларированные алюминием и железом слоистые алюмосиликаты в процессах очистки водных растворов от хрома (III)
Реферат: Исследована адсорбция от хрома (III) из водных растворов на модифицированных монтмориллонитовых и каолинитовых глинах Казахстанских месторождений в динамическом режиме. Показана высокая эффективность удаления хрома из водных растворов путем сорбции на пилларированных алюминием и железом монтмориллонитах и каолинитах. Преимуществом предлагаемых сорбентов является то, что природные глины добывают во многих регионах Казахстана в непосредственной близости от возможных мест потребления, что способствует расширению масштабов их применения для очистки вод тяжелых катионов, в том числе от хрома.
