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.

Regularities of the processes of transport and deposition of soil material by water flows small depth The main objective of this work by the example of soddy-podzolic soil of different degree of wash off quantitatively assess the ability of small depth flows at the system level «flow-soil» to transfer certain mass of soil material. Determination of quantities transfer and deposition of soddy-podzolic soil of different degree of wash off spend on a large erosive tray. In the experiments was determined by the following indicators: the average velocity of flow and turbidity of water, the radius of the transported and deposited in the stream bed of aggregates and other. These indicators are used for verification of the theoretical equation transporting capacity.  

Application of the European soil standards in the territory of Azerbaijan At present the integration to the European and international structures goes on in many directions, including scientific. Against a background of globalization it is fundamentally important to form an adequate soil-information space which would ensure progressive international cooperation in the field of soil science. As is known, the new digital soil database of Mediterranean and Caucasus Countries’ territory in the format of the soil geographical information system of the European Union (EU) is being prepared within the program for the Extension of the European Soil Database (ESDB). These researches intend to create the Soil Geographical Database of Eurasia at scale 1 : 1, 000, 000 as a part of the European Soil Information System (EUSIS). The current stage of the Azerbaijan soil resources inventory on supranational level is closely linked with the processes of adaptation of the country to the conditions of new geopolitical realities. It is of fundamental importance to preserve and develop the national scientific and practical traditions and their harmonious integration with the EU soil inventory. Taking into consideration the urgency of the problem, we have made researches in order to create the digital data base of the soils of the Republic of Azerbaijan. The digital soil map of Azerbaijan has been prepared in a scale of 1:1000000 using modern geoinformation technologies and taking into account the ESDB requirements. During the analysis of soil database of Azerbaijan, some difficulties that impede the integration process to the ESDB were revealed. Generally, the work that has been done brought to a conclusion that the knowledge available on soils of Azerbaijan makes the integration to the EU soil-geographic data base possible.

Bayesian analysis of 2?2 contingency tables relative proportions A new standard expression for distribution of epidemiological risk ratio estimates has been found out using two by two methods of study. Comparing homogeneous groups the distribution is operational within wide-ranging conditions studying both rare and frequent events. Support value of the distribution formula will increase primarily in cases with small amount of the cases or controls observed. Using the derived distribution excess mortality from lung cancer of the Mayak PA workers was associated with radiation exposure with high reliability of the observation.

The comparative study of the influence of pathogenic factors on the formation of congenital and acquired neurosensory hearing loss The aim is to carry out a comparative analysis of pathogenic factors influence on the formation of congenital and acquired NHL and on the formation of complex pathologies and peculiarities of psycho-physiological status of the child. Сhildren with NHL have a physical developmental lag in the process of individual ontogenesis, which is manifested in the lack of functional maturity of somatic and visceral systems of the body, the simultaneous presence of different of anomalies of growth and development. The comparative analysis of the influence of the environmental pathogenic factors on the formation of the congenital and the acquired NHL showed that the condition of intra- and inter-hemispheric integration and the nature of spectral power density of the EEG ranges in children with NHL can act as a functional criterion for the pathology development.

Problems and prospects of the main biogenic elements intramolecular isotope correlations using as a new resource of different aetiology pathologies diagnostics It is shown that chemical elements isotopes fractioning in chemical and biochemical reactions is based on two fundamental kernel properties — the mass and the spin; differences between them can affect on both chemical reactions speed and reactive systems energy state. In some cases deviations in mass-dependent linear isotopic effect for most of uneven isotopes from hydrogen to uranium are observed. These fractioning peculiarities can be used: in living organisms — for early disease detection of different aetiology pathology; in abiogenous natural systems — for new methods of heavy elements isotopes enrichment development.
