#2 / 2015Biological SciencesKagazezheva N.Kh., Kolomiytseva N.S., Doronina N.V.Features of adaptation alterations of cardiorespiratory system of an organism of young football players Features of adaptation of oxygen-transport system of young football players to performance of intensive physical activity are analyzed. Scientific researches were conducted on the basis of educational - research laboratory of the Department of Biomechanics and Medicobiological Disciplines of the Adyghe State University and in the diagnostic center of Sport Center of the Maikop State University of Technology with participation of football players aged 13-16 years who passed training of the preparatory period. The obtained data indicate that systematic football occupations are followed by a natural economization of functions of oxygentransport system and promote acceleration of processes of restoration and decrease in physiological cost of loading in process of long-term adaptation at teenagers
Indexes of heart rate variability after standard physical training of young athletes specializing in judo and unarmed self-defence Studying the mechanisms of adaptation at young athletes during the training process is of theoretical and practical significance for sports physiologists. Currently, an objective method of studying the system of the body, especially the cardiovascular system, is the analysis of heart rate variability which allows fast control of the athlete’s state. Known as periodic changes of heart rhythm, the heart rate variability reflects the state of vegetative nervous system which is an important component providing adaptive reactions of the body. At the same time, a change of the vegetative status may reflect both a positive adaptive response and the beginning of development of prenosological states. In order to obtain the most complete information on the state of the regulatory systems, we must assess the level of functional reserves, for the determination of which functional tests should be conducted
The polymorphisms of ITG and SEL genes associated with the bronchial asthma, complications of peripheral and coronary atherosclerosis and mammary gland adenocarcinomas at inhabitants of the Adyghea Republic For many years, the leading places in structure of the reasons for the population mortality in the Adyghea Republic are taken by cardiovascular (CV) and oncological diseases. Relevance of this research is caused by searches for early molecular and genetic markers of multifactorial diseases. Distribution of single nucleotide replacements (SNP – single nucleotide polymorphisms)of genes of integrin adhesion molecules ITG (ITGA2 C807T, rs1126643, ITGB3 Leu33Pro, rs5918) and SEL selectins (SELE Leu554Phe, rs5355; Ser128Arg, rs5361, SELP Thr715Pro, rs6136) at inhabitants of Adyghea Republic is investigated by SNP method in 44 samples of DNA of donors (n=10) and sick people (n=34) with CV (n=17), malignant new tumors( MNT) (mammary gland adenocarcinoma, n=8) and chronic inflammatory diseases of lungs (the bronchial asthma (BA), n=9). As a result of research it has been obtained that 128Arg polymorphism of SELE gene – endothelial E-selectin (χ2=6,66; P=0,01; OR=15) and platelet P-selectin SELP Thr715Pro (χ2=4,55; P=0,03; OR=7) are statistically significantly associated with system pathological processes. The carriage of pathological homozygous Arg128Arg of a genotype and «mutant» 128Arg SELE allele is associated mainly with peripheral (respectively χ2=12,31; P=0,002; OR=39; χ2=21,96; P=0,000003; OR=100) and to a lesser extent coronary atherosclerosis (χ2=4,09, P=0,04; OR=10). A molecular and genetic predictor of an ischemic and hemorrhagic stroke is the carriage of 715Pro SELP gene allele (χ2=7,54, P=0,006; OR=17)
Use of adsorbents to increase the ecological and biological value of beef The aim of the research is to study the efficiency of using adsorbent preparations of Helaton and Toksi-nil Drei in diets with the excess level of heavy metals to increase an ecological and nutrition value of the bull-calves’ meat production. To increase an ecological and nutrition value of beef it is advisable to include combined adsorbent preparations of Helaton and Toksi-nil Drei in the bull-calves’ diets if food for animals contains the excess level of heavy metals
Evolution of the Adyghea Republic toponymy formatio The paper presents the results of the etymological and semantic analysis of oikonyms and a periodization of stages of the population moving in the Adyghea Republic. More than 232 names of settlements in the Republic of Adyghea are investigated on the basis of materials of the 2010 population census. The stratigraphic analysis of toponymic layers is made. The main toponymic background of Adyghea oikonyms is identified
Adaptive opportunities of cardiovascular system at students, working on computers at informatics lessons in the conditions of fatigue prevention The paper discusses the influence of computers on a functional state and adaptive opportunities of cardiovascular system at students at informatics lessons. The adaptive response of cardiovascular system at students during the work on computers can be regarded as a less effective, more energy-intensive and imperfect model of adaptation. This is supported by alterations of an index of functional changes and type of self-control of blood circulation. Efficiency of carrying out fatigue prevention at lessons with the use of computers is revealed

MathematicsStash A.Kh.On some properties of full and vector frequencies of signs and roots of solutions to linear homogeneous two-dimensional differential systems The paper explores the ranges of full and vector frequencies of signs and roots of linear twodimensional differential systems and the continuity of extreme frequencies using a set of two-dimensional systems. The paper shows that for any pre-set natural number p the linear two-dimensional differential system with periodic coefficients is provided. Sets of various values of full (vector) frequencies of signs and roots of uncommon solutions to this system consist of not less than p of various essential numbers. Existence of two-dimensional differential system with limited coefficients with the same calculating range of full (vector) frequencies of signs and roots is proved. In addition, the point is given in space of linear two-dimensional differential systems with continuous limited coefficients, in which each of extreme frequencies of signs and roots suffers jumps both up and down at disturbances of the coefficients disappearing on infinity

On the velocity of thermophoresis of solid two-layer large and moderately large aerosol particles In the Stokes approximation, the theoretical description is carried out of steady-state motion of large and moderately large solid double-layer spherical aerosol particle in a nonuniform in temperature monatomic gas, when the thermal conductivity coefficients of the core and cover of the two-layer particle are considerably different in value
Radiation of the damped harmonic oscillator (the methodological aspects) The model of radiation of the damped nonrelativistic oscillator is the basic one for the description of many phenomena discussed in electrodynamics, radiophysics and quantum optics. However, in standard textbooks, the topic is presented briefly. Sometimes important details for practical calculations are omitted. In this paper, we derive exact formulas for spectral angular distribution of the damped oscillator radiation. The approximate expressions for oscillator with low attenuation coefficient have been obtained. Attention is paid to the physical interpretation of the formulas obtained

Assessment of quality indicators of thematic tasks of the subject test module and level of its mastering The paper explores the techniques of a quality assessment of the developed tests and level of mastering a learning material on the basis of algorithmic procedures of the standard office Microsoft Excel program and graphical representation of outcomes of their analysis. Graphic dependences have been obtained to examine the solubility and discriminativeness coefficients of thematic test tasks, test reliability and levels of mastering a learning material, both for the basic structural (didactic or modular) units, and in general. The analysis of graphic materials enables us to determine not only the qualitative characteristic of the developed test modules, but also to find thematic test tasks with a low discriminativeness. This will make it possible to come in due time to the relevant administrative decisions on their completion and the subsequent use for monitoring of quality of mastering the learning material at the accepted corresponding criteria for an assessment
