At present, there is great interest in the problem of brain lateralization and dynamic changes in functional interhemispheric asymmetry due to the new knowledge obtained in the field of sports physiology. This paper explores the influence of durational table tennis playing on the indices of sensorimotor asymmetries, as well as neuro-physiological indicators in adolescents with different lateral phenotypes. To evaluate interhemispheric relationships, the α rhythm sampling rates (8–9 Hz, 10–11 Hz, 11–13 Hz) were analyzed, as well as the coherence of α-rhythm with a frequency of 10 Hz. We have established that after long hours of playing table tennis, athletes show an increased asymmetry of the α-rhythm in the occipital regions in the high-frequency range, especially in right-handers, and en-hances of the coherence of the EEG in the α-range as compared to untrained peers.

According to three-dimensional localization of sources of increased electrical activity of the brain with the help of the BrainLoc program, resentment and guilt are deep forms of aggression; verbal, physical, indirect aggression and negativism – superficial; and irritability and suspicion – intermediate. A detailed localization of these forms of emotion is given in the paper. The prerequisites for a new classification of aggressive manifestations are discussed – on the cerebral vertical, that is, on the level of generation of the focus of increased electrical activity of the brain.

The authors have discovered that the largest encounter rates of a polymorphism are characteristic of genes of blood clotting of PAI-1, MTRR, MTR; and the least encounter rates are indicative of genes of FGB, ITGB-3, FV, FII, FVII, and MTHFR. In this paper, we examine genes of a folate cycle and clotting system at which polymorphisms occur more often than at other genes of blood clotting. By means of a hypothesis of the distribution law of a random value (Pearson's criterion) of encounter rates of a polymorphism of these genes, connection with blood-group specificity and Rh affinity at women was established. Polymorphisms of alleles of MTR are significantly associated with patho-logical processes of blood clotting system at women with blood group O – I0I0D+ and D– affinity, with blood group A – IAI0D+ affinity, and with blood group AB – IAIBD+ affinity; for other chosen cases such association is unproved.

The paper shows the influence of polymorphisms of genes of angiotensin-converting enzyme (ACE) and Bradykinin Receptor of type 2 (BDKRB2) on indicators of the oxygen transport system (OTS) of young men depending on the level of their physical activity. At athletes whose level of the motive mode is high (480 minutes/week), ACE gene polymor-phisms are authentically associated with the average volume and the size of erythrocytes, content of oxygenic hemoglobin and oxygen tension in blood. BDKRB2 gene polymorphisms point to the level of a physical condition of an organism, adaptation opportunities of cardiovascular system and tolerance to physical activities.

The paper presents the generalized results of monitoring 90Sr and 137Cs content in the soils of Tula, Orel and Ryazan regions, its average values and standard intervals. There is significant spotting of radioactive contamination in soils. The standard interval of changing the 137Cs content in the soil of the Tula region is equal to 23–221 Bq/kg (or 0,9 to 1,8 CI/km2), in the Orel region, 43–117 Bq/kg (0,36–0,95 CI/km2), and in the Ryazan region, 75 Bq/kg (0,61 CI/km2), and the standard interval of changing the 137Cs content in the soil is equal to 44–106 Bq/kg (0,36 to 0,86 CI/km2). The 90Sr content in the soils of these areas is low. In all the surveyed areas, the risks of agricultural production contaminated with 90Sr above the standard are practically absent. The results on radioactive soil pollution in human settlements and the data on local radiation monitoring of agricultural land in reference areas are in good agreement and successfully complement each other.

The article traces the dynamics of changes in the acid-base properties of the soil, the content of exchange bases and heavy metals during prolonged use of mineral fertilizers and plant protection products in the field crop. After ten years of research, a decrease in pH from the initial level of 0,21 units was found, that the resistance of TM to the action of factors in the experiment can be arranged in the following sequence: Ni>Cu>Co>Pb>Zn>Cd. The results obtained on the contents of heavy metals in the soil provide a basis to assess the environmental situation in agro-ecosystems of Krasnodar region in making fertilizers in recommended doses, as completely satisfactory and provides getting environmentally safe products.

The work presents data on the specific composition of amphibiotic insects of the Kartsadon small mountain river, the left tributary of the Fiagdon River (the Terek River basin). In the benthos, representatives of the orders of the subspecies mayflies (Ephemeroptera), stoneflies (Plecoptera), caddis flies (Trichoptera), Diptera (Diptera) are noted. Among the detachments caddis flies (12 species), mayflies (8 species), stoneflies (7 species) and finally, Diptera (5 species) dominate. All species belong to the oligosaprobic, litterophilic fauna, and are an essential part of the natural forage reserve of salmonids, along with the Amphipoda squad.

For a specific type of cubic differential system we find that, under special coefficient conditions, it cannot have three centers and six saddles. We prove that if the system has nine singular points in a limited part of the phase plane, then five of them are the centers, and four are saddles. An example of such a system is given.

We have established that the full hyper frequencies considered as functionalities on a set of solutions of the linear uniform differential equations above the third order with the continuous coefficients limited on a semiaxis are not residual (that is can change at changing solution on a final piece). Besides, at any beforehand set , an example of the linear uniform differential equation of n order, for some solution of which full and vector hyper frequencies do not coincide, is given.

In this work, we carry out the statistical analysis of the stochastic model of moisture transfer. To determine the statistical parameters, the Adler’s equation comes down to a sequential solution of six one-type problems, solved by the iteration method using the sweep algorithm. The results of the calculation obtained by the formulas of the sweep method are stable. Based on the algorithm considered in the work, we developed a program implemented in the Turbo Pascal environment and calculated a test case for the values of random functions listed in the program.

We have obtained the analytical solution describing the stationary motion of electrolyte in magnetic field for a case of the Cartesian geometry of system taking into account interaction of a free surface of electrolyte with air. Comparison of the results of the theory and a field experiment shows that influence of air on the movement of elec-trolyte is very small and in order to achieve greater agreement it is necessary to use methods of numerical modeling with the corresponding more general statement of the problem.

The work explores kinetics of natural water electrocoagulation with the help of the granulated aluminum sulfate, the polymerized aluminum oxychloride and compositions made on their basis. By using a complex of physicochemical methods, we have found out that speed and mechanism of electrocoagulation in the systems under study is determined by correlation of different types of electrostatic interactions. They influence the double-layer parameters and electrophoretic mobility of the particles. We have established the synergistic effect of coagulants and nitrite-hydroxide mixtures in the conditions of electrocoagulating purification of natural waters.

The study of queues in health care systems allows us to define the criteria for the operation of the hospital system, among which the most important are the average waiting time in queue of hospitalization and the average length of the waiting queue. We use such information to select the appropriate level of service. Currently existing versions of the applications, features of their maintenance, shaping queues, the location, the number and organization of the service channels was the reason for the emergence of a large variety of queueing systems. Theoretically, the possi-bility of new advances in medicine is unlimited, but in practice, there is a shortage of doctors and nurses, lack of medicines, facilities, finance, etc. In this regard, there are many urgent problems, the solution of which would allow us to use the limited resources available with maximum efficiency. Our proposed work deals with the organization and planning of health services.
