O. Dzenzerska, S. Rudenko Seasonal features of CNP-stoichiometry of transboundary rivers of Northern Bukovina
Abstract. During the spring flood in all transboundary rivers of Northern Bukovina, the limitation of stoichiometric availability of Phosphorus has been established: the molar ratio of DIN:DIP varies between 66-380, which is significantly >38 (the lower threshold of stoichiometric Phosphorus limitation). During the summer period, the molar ratios DIN:DIP in the Prut and Siret rivers were significantly <22, which indicates the limitation of the stoichiometric availability of nitrogen. In the Dniester River in this period, the corresponding ratio is in the range 22-38, where there is no pronounced stoichiometric limitation between these elements. The stoichiometric ratios of DIN:DIP and DIC:DIP during the summer period were decrease in compared with the period of spring flood. This is due to an increase in the molar Phosphorus concentration in the summer period against the background of a more or less stable level of Nitrogen and Carbon throughout the year.
Keywords: CNP-stoichiometry, Nitrogen, Phosphorus, Carbon, the rivers of Northern Bukovina.

O. Hromyk, O. Ilyina Radionuclides and heavy metals in soils and waters on the territory of radioactive contamination in Volyn region
Abstract. An important environmental issue is the need to develop cost-effective measures to reduce contamination of soil and water with heavy metals and radioactive substances. Soil and water are intensively used in agricultural production and require analysis of their condition due to the risk of food contaminants. The estimation of radionuclides and heavy metals in the soil and surface waters on the territory of radioactive contamination in the Volyn region was conducted. It shows that the proportion of 137Сs, 90Sr exceeds the maximum permissible concentration of heavy metals. The study area requires a long process of social and economic rehabilitation, which involves restoration of natural resources and safe living conditions, the introduction of advanced technologies for the production of environmentally friendly agricultural products.
Keywords: radionuclides, heavy metals, water, soil, maximum permissible concentration, radiological analysis, radioactive contamination.

Yu. D. Shuisky, O. R. Andrianova Basical research results of long term fluctuations of the sea level along the world ocean coasts
Abstract. As it was represented (per various estimates) the World Ocean level can be rise by a value from 0,07 to 0,55 m/100 years. In the 19th century the average rates were +1,2 mm/year and in the 20th century it was +2,8 mm/year. The average rate of the World Ocean level during past 130 years was 1.76 mm/year. In the past 25 years, the average rate has exceeded 3,5 mm/year. In several hydrometeorological points essential differences were discovered by in comparison with average values. A concept for optimal averaging is developed. During the period 1880-2010 along eastern coasts of the Atlantic Ocean the sea level increased by 0,16 m, along the western coast – by 0,33 m and in general – by 0,19 m. During the same time along the eastern shores of the Pacific Ocean the growth was 0,16 m, along the western coast – by 0,29 m, and in general – by 0,23 m. Along the coasts of the Indian Ocean the average sea level growth was 0,12 m (at minimums) and 0,24 m (at maximums). These values were formed on the background of global values for the whole World ocean level: at minimums – by 0.17 m, and at maximums – by 0.23 m.

Abstract. Given the impact of hypovitaminosis D on the development of complications of pregnancy that cause maternal and infant mortality, this study is an actual problem of modern obstetrics. Note that during pregnancy and lactation, even when taking multivitamin complexes with a vitamin D content (up to 400 IU / day), a high frequency of hypovitaminosis D remains. According to the data, in this category of women in 73% of cases the level of vitamin D is < 20 ng / ml, and in newborns, vitamin D deficiency is noted in 83% of cases. The results of the study showed that only 4.6% of pregnant women had 25 (OH) D in blood serum within the normal range, insufficiency was noted in 13.6%, and vitamin D deficiency in 81.8%, which corresponds to the average value for Ukraine . Understanding of this problem calls for the use of therapeutic and prophylactic measures to eliminate the vitamin D deficiency both at the stage of pregravid preparation, and during pregnancy and lactation.
Keywords: vitamin D, pregnancy, polyhydramnios, сomplications of pregnancy, vitamin D deficiency.

O. O. Chugay Functional disturbances of immune response in different periods of experimental pneumonia development
Abstract. One of the main mechanisms of protecting immune system against pathogens is functioning of different parts of the immune system of respiratory mucosa. At the same time, there was activation of humoral immunity, manifested by increase in B- lymphocyte level and circulating immune complexes in the blood both in early and late periods of experimental pneumonia. This condition may be caused by the nature of the agent. Since experimental pneumonia in guinea pigs was provoked by Staphylococcus aureus, which is a gram-positive bacterium, humoral immunity plays a leading role in combating this infection.
Keywords: experimental pneumonia, T-lymphocytes, B-lymphocytes, circulating immune complexes.

Abstract. In modern football, the search of the criteria, which are characterized by sustainable biological nature and might be informative for the management and prediction of individual sport training, is of growing interest. We consider that individual- typological properties of higher parts of the central nervous system can meet these requirements. Thus, the goal of the research was to find out what individual-typological properties of higher parts of the central nervous system are fixed genetically and to determine their correlation with the indicators of special preparedness and bioenergetics of football players. We performed the investigation using “Diagnost-1M” and “D & K-Test” computer devices on 13 pairs of monozygotic (MZ) and 12 dizygotic (DZ) twins who did not go in for sport and 26 professional football players, and determined typological properties of the nervous system. Besides, we found physical and technical preparedness of the football players. We found the expressed hereditary conditionality for the functional mobility of the nervous processes (FMNP) (70%) and the relative predominance of genotypic factors (50%) for the strength of the nervous processes (SNP) and the equilibrium of the nervous processes (ENP). We determined the predominance of phenotypic factors (30%) for the indicators of sensorimotor reactions. The indicators of bioenergetics metabolism, physical and technical preparedness, expert evaluation of game activity of the highly qualified football players depended on the genetically determined properties – the functional mobility of the nervous processes.

Abstract. This paper deals with cluster systems. Authors have paid much attention to architecture of these systems. They have also explained all laws and paradigms that are related to computer cluster systems. The authors propose a new method rating of nodes in inhomogeneous cluster systems. This method based on two tasks: proof of work and proof of trust. Task proof of work consists of two steps, on the first server sends requests for all nodes and takes information about software and hardware. After this server makes the decision if server can use this node for calculation or not. If all is ok, the server starts step two and sends simple task for calculation. Using a result of the task server makes rating table with nodes, which can be used for calculation.
