The Influence of the Spatial Variability on the Goal-Directed Behavior Organization Serkova V. V., Nikolskaya K. A. The influence of the spatial variability on the goal-directed behavior organization in adult mice line F1 from DBA/2J and C57BL/6J was studied. It has been found that sudden change of initial structure of the maze during the moment of imprinting of spatial information has negatively affected on possibility to form the adaptive behavior in accordance with the offered task conditions. It is assumed that the constancy of the initial spatial information can be an system factor which together with the other will ensure the success of the cognitive process.

Spatio-Temporal Variability of Phytoplankton State of the Seversky Donets River Reshetnyak O. S. It was considered the variability of quantitative and qualitative indicators of phytoplankton communities in different parts of Seversky Donets. It is shown that the characteristic feature of the development of phytoplankton in period 2002–2011 is high variability of quantitative indicators, suggesting an unstable state community. In the composition of phytoplankton was recorded from 12 to 39 species, the dominant complex were compiled diatoms and green algae. Aquatic ecosystems are able to anthropogenic ecological stress by level of phytoplankton development.

Investigation of the activity some 8-aminoderivatives of 3-methyl- 7-?-hydroxi-?-isopropoxipropylxanthines at the experimental hyperlipidemia. Ostapenko А. А., Belay I. M., Romanenko N. I. We made research in analysis of the antioxidant features of the newly synthesized derivatives of 3-methylxanthine in experimental hyperlipemia in rats. The results of the computer prediction of the possible manifestations of the biological activities indicate that the majority of the analyzed compounds can influence on the different sides of lipid metabolism. Markers of the influence on the activity of lipid peroxidation and the complex antioxidant activity during administration  of derivatives 3-methylxanthine were studied. This screening has allowed to identify some patterns of connections between the structure and the direction and severity of changes in the antioxidant properties of the blood of experimental animals. In addition, prospect of further pharmacological studies of the effects of synthetic analogs of xanthine are confirmed by appropriate patents and informational letters.

30 years' Changes of Probabilistic and Information Characteristics of the Humus Content in Southern Chernozems in Western Siberia The analysis of transformation of the probabilistic-statistical distributions (PSD) of the humus content in southern chernozems at the studied territory in the whole, situated on the Priirtyshsky uval for the 30-year period revealed existence of the tendency to decrease in the humus content in the top layer and its increase in underlying layers of soil. Transformation of PSD of the humus content is followed by very essential reduction of statistical entropy up to 60% of initial value that speaks about essential change of a condition of chernozems in spite of the fact that taxonomically soils don't change. The analysis of information divergence showed that the revealed tendencies in a sandy loam version are expressed more strongly, than in the loamy soils. And the greatest transformation of PSD of the humus content for the studied period happened in a layer 30-50 cm due to increasing of the low boundary of the interval of variation. The revealed transformations of PSD are interpreted from the point of view of interaction of soilforming, climatic and landscape and exogenous processes.

Consequences of eco-toxicological effects of hazardous heavy metals compounds on the benthic communities of river ecosystems The paper presents the results of the analysis of long-term regime hydrochemical information about the hazardous heavy metals (mercury, cadmium and lead) content of the river waters and hydrobiological information about the structural organization of the benthic communities. The possible  changes assessment of the ecological status of river ecosystems was conducted. It is shown, that the variability of the quantitative indicators of the benthic communities is response to the transformation of the component composition of the aquatic environment river’s.  The strengthening processes of environmental regression of  benthic communities takes place in river ecosystems with a high level of contamination of the toxic heavy metals.

The functional state of the organism of calves during cold method of cultivation. Кostesha Nikolay Yakovlevich, Makarevitch Veronika Gennadievna For  the experiment 2 groups of calves were taken. An experimental group of  5 days old calves was put into individual cabins where the temperature was minus 4-5C. The control group was put into similar  cabins where the temperature was 11-12oC. The test of peripheral blood  in the experimental group showed that the quantity of erythrocytes increased significally compared with the control group of calves. The authors believe that moderate stress (according to the increase of cortisol in peripheral blood) stimulates erythropoiesis. Since the 7th  day of the experiment the calves began to gain weight up to 25% compared with the control group.

Evaluation of the rate constants reactions of the alkyl, allyl and aryl radicals with hydrocarbons with use the artificial of neural network Evaluation of the rate constants reactions of the alkyl, allyl and aryl radicals with hydrocarbons with use the artificial of neural network Tumanov Vladimir Evgen’rvich This paper discusses the use of feed-forward artificial neural network to predict the rate constants of organic molecules in the bimolecular radical reactions R + R1H in the liquid phase on the experimental data. The hybrid algorithm of calculation of rate constants of bimolecular radical reactions on the experimental thermochemical data and an empirical index of the reactionary center is offered. This algorithm uses an artificial neural network for a prediction of a classical barrier of bimolecular radical reaction at a temperature of 298 K, a database of experimental characteristics of reaction and Arrhenius's formula for calculation of a rate constant. Results of training and a prediction of the network are discussed. Results of comparison of logarithms of the calculated and experimental of the rate constants are given.
