Description
The stability of strongly basic anion-exchange membranes MA-41-2P (JSC "Schekino-Nitrogen", Russia) and AMX (Tokuyama Soda, Japan) under intensive current regimes was investigated in the current study. The process of water molecules dissociation at current densities above the limiting one in 0.01 M sodium chloride solution was studied in detail. The length of the electroconvective instability at the membrane / solution interface at currents exceeding the limiting current was measured by laser interferometry

Description
In the article the mathematical model of the space charge region in the bipolar membrane is considered. The structure of the space charge region under passing of electric current, and without electric current is discussed. The results of experimental studies of water dissociation in the bipolar membrane in the presence of chromium(III) are discussed

THE EFFICIENCY OF THE "MYCOSIM SP +" ENZYME FEED ADDITIVE IN THE DIET OF QUAIL
Description
The article presents the materials on the effect of "My-cosim SP +" enzyme feed additive on growth and de-velopment, biochemical and morphological parame-ters of the quail and the results of post-mortem autopsy of quail to determine the effect of additives on changes of the quality and flavors of the meat

DYNAMICS OF RESTORATION OF BIOLOGICAL PROPERTIES OF BLACK SOILS POLLUTED WITH OIL
Description
Negative impact of oil on biological properties of soils right after pollution is shown in the article. Eventually, there is their restoration. However, even in some years after pollution, the biological properties of soils aren't restored completely

Description
In the article we have investigated the influence of nickel oxide in the amount of 100, 1000 mg/kg of the soil (1, 10 MPC), combined with the influence of an alternating magnetic field of induction of 50, 100 and 650 µT power frequency of 50 Hz on the biological properties of alkalinity black soil

Description
The article gives an assessment of resistance of the brown typical soil of the Utrish national reserve to pollution with heavy metals (Cr, Cu, Ni, Pb) and oil on biological indicators

BIOLOGICAL FEATURES OF THE BLACK SOIL DEPOSITS IN THE BOTANICAL GARDEN OF SFU
Description
We have studied changes in flora, humus content, peroxidase activity and polyphenoloxidase in ordinary black soils in natural succession of different-age deposits. We have also selected stage successions in uneven deposits

Description
This article presents an assessment of the stability of the black soil of the Crimea to contamination with heavy metals (Pb, Cu, Cr, Ni) and oil using biological indicators

Description
This study was aimed on testing of IRAP markers developed at plum on varieties of peach, Russian plum and cherry plum and genotyping of home and foreign varieties of plum, followed by an analysis of the data. During the testing of the markers have been identified as a high level of polymorphism between genotypes of plum and between the studied species. On the basis of the results obtained by genotyping 15 samples of Prunus was built dendrogram. Cluster analysis was divided into 3 groups corresponding varieties of P. persica, P. domestica and a common group for varieties of Russian plum and cherry plum

Description
The optimum combination of quantitative and qualitative relationships between structures of organic and mineral wastes of various industries provides the formation of compound composts, which improves its physical, chemical and biological properties of the soil, helps conserve macro- and micronutrients, organic matter, enhance ecological niches system, to ensure the development of ecological trophic groups of microorganisms
