    Physiological features of cardiovascular system of male athletes in the age range of 17-46 years

    The paper presents the results of a study of the cardiovascular system in athletes and untrained males at the age of 17-46 years. Functional changes in cardiovascular system of athletes are caused by age processes and specifics of long-term adaptation. The work shows various variants of the organization of a functional condition of cardiovascular system at rest and when performing the dosed physical activities. Increased functional reserve of cardiovascular system is most pronounced at athletes of period I of mature age, coaching endurance at whom the economization of energy expenditure at expansion of functional reserves of a myocardium was observed. In group of period II of mature age decreased variability of heart rate is noted; at athletes coaching endurance it is combined with increase of stress index, and at athletes coaching force it is combined with power reduction of a high-frequency spectrum. At the same time, at the latter, operability of the left ventricle during the dosed physical activity considerably lags behind growth of minute volume of blood flow. At untrained persons the increased minute volume of blood flow during standard loading is followed by decrease in operability of the left ventricle which can be regarded as an inadequate response associated with fatigue. Spotted unresponsiveness to the standard load by systolic and diastolic blood pressure in a group coaching endurance is noted, while in group coaching force during standard and specific probe, hyperkinetic reactions are noted. In the conditions of application of physical activities, the interrelation of a vagosympathetic index and minute volume of blood flow is shown that testifies to direct dependence of vagosympathetic balance with intensity of blood circulation at 40-46 year-old athletes coaching endurance. In group of athletes of 40-46 years coaching force, close dependence of the hemodynamic parameters on the performance variability is revealed. In group of 40-46 year-old untrained persons, dependence of indicators of heart rate variability on the degree of myocardial relaxation is noted.

    Long-term variability of an annual runoff of the rivers in the Northwest Caucasus and features of its spatial distribution

    The paper discloses factors and features of spatial distribution of long-term variability of an annual runoff of the rivers in the Northwest Caucasus. Corelations of variation coefficients of the annual runoff with the average elevation of the river reservoirs are investigated. The uniform dependence reflecting the law of long-term variability reduction with increasing average elevation of reservoirs has been obtained. The map of isolines of variation coefficients of the annual runoff, uncovering features of its spatial distribution, is implemented. The conducted researches expand theoretical and applied aspects of regional hydrological researches.

    Evaluation of the stability of brown forest soils of the Adyghea Republic foothills to pollution with toxic microelements according to biological indicators

    Contamination of soils in foothill forests of Adyghea Republic with zinc, cadmium, molybdenum or selenium deteriorates the biological properties of the brown forest soils. The conducted research has shown that the degree of reduction of biological indicators is directly dependent on the concentration of pollutants in the soil. According to the degree of toxicity to the biological properties of brown forest soils the elements under study form the following sequence: Zn > Cd > = Se > Mo.

    The study of positive and negative effects of migration of the population for the social-economic development of the countries of the world

    This paper examines the impact of immigration processes on social and economic development of the state, as well as on interethnic relations. The effects of immigration are mixed: on the one hand, objective needs in the country's labor force are replenished, but, on the other hand, interethnic tension is triggered, crime situation is worsening and the competition in the labor market is growing.

    Korteweg-de Vries equation and mathematical models of socioeconomic systems

    In this paper we give a method of constructing Partial differential equation that describes the mathematical model of the problem of information transfer in the learning process. To construct such a model, we established a correspondence between the terminology of differential equations and that of the field of information transmission. As an example, the Korteweg-de Vries equation is examined. Also we consider some of the properties of solitons.

    Approach to formation of a total assessment of the level of learning a curriculum material at intermediate certification of trainees on the basis of the weighed coefficients of the estimated indicators

    The paper presents the technique of the solution of a non-standard problem related to determination of coherence of expert opinions on a set of the estimated signs to justify a total assessment of the level of learning a curriculum material at intermediate certification of trainees. New approach is proposed on formation of both quantitative structure of the estimated examination card signs, and determination of the weighed coefficients of the estimated signs. The general criterion for formation of a total assessment is defined. Recommendations are given on the formation of the general total assessment of the trainee in examination or test. Practical realization of such approach in educational process will allow better monitoring of level and completeness of mastering a training material at the accepted corresponding criteria of an assessment.
