    Modeling and the numerical analysis of the process of binary electrolyte transfer in the desalination channel of the electrodialytic device in the potentially static mode

    The paper discusses the modeling and the numerical analysis of the process of binary electrolyte transfer in the desalination channel of the electrodialytic device. The authors propose various mathematical models of ion transfer in the potentially static mode in the form of system of the quasilinear equations with private derivatives. Transition to a dimensionless kind is carried out and presence of some small parameter ε>0 is shown at the senior derivatives in the equations. If speed of electrolyte circulation through the desalination chamber is considerable there is one more small parameter λ>0. The special stretched system of coordinates is used for the numerical analysis. The basic laws of occurrence and development of a spatial charge in the desalination channel of electrodialytic device are revealed. Various asymptotic and numerical methods of the solution are proposed.

    Designing and building resistance furnaces for the monocrystal growth device

    The paper discusses a method for calculating the temperature distribution along the length of resistance furnaces. The method has several advantages: it reduces the time to build a furnace, saves resources and leads to the desired result. Muffle material and heat insulation material are taken into account. A resistance furnace with a given temperature distribution was built based on the calculation.

    Intrapopulation and ecological-geographical variability of gentian Pyrenean (Northwestern Caucasus)

    The paper examines intra- and interpopulation variability of a gentian Pyrenean in Alpine and subalpine phytocenoses of the Northwest Caucasus. Based on the majority of dimensional signs and the number of metameres of a flower, the authors show that there is a differentiation of cenopopulations of this species from various phytocenopses. It is assumed that these signs are the most plastic and depend to a greater degree on influence of environment factors.

    The dynamics of the statistical heart rate indices in the adolescents learning in the Physical Training Faculty

    The participants in this study (40 adolescents) were all students at a Faculty of Physical Training who were surveyed in the dynamics of the first and second year of training. The dynamics of heart rate statistics was studied in autumn (in the dynamics of the first year of training in semester 1 and at the beginning of the second year of training), as well as before and after examinations in the period of winter and summer examinations. Physiological mechanisms of adaptation of young men to training process at Faculty of Physical Training promote strengthening centralization of heart rate control only in reply to examination tension that occurs at the expense of reduction of a parasympathetic tone and increase of the adrenergetic influences, capable to provide short-term mobilization of additional energy resources.

    The neurophysiological status and its relationship to a morphotype of sportsmen-track and field athletes

    This paper reports upon research on the neurophysiological status at sportsmen-track and field athletes. It is revealed that somatotypological features influence the character of display of the basic properties of nerv-ous system: lability, mobility, force and degree of balance of nervous processes. The obtained results are attractive for a choice of tactics and strategy of track and field athlete training, taking into account a current condition of nervous system.

    Age dynamics of oxygen consumption at relative rest of persons with the various modes of impellent activity

    The level of energy potential of a biosystem can serve as a criterion for stability of an organism to a wide range of adverse effects. Increase in maximal oxygen consumption (VO2max) is possible only at application of great in volume and intensity physical activities. According to the theory of oxidative stress the increase in power loading can lead to accumulation of oxidative damage and to fast exhaustion of a biological resource of an organism. On the other hand, high energy expenditure during a working phase is accompanied by considerable economization of activity in a condition of relative rest, consequently, by decrease in intensity of free radical oxidation. In the present research, an attempt is undertaken to quantitatively assess a degree of this economization on the basis of indicators of the main exchange and oxygen consumption in a condition of relative rest at persons with high level of impellent activity.

    Polymorphisms G197 and 197A of the pro-inflammatory IL-17A gene associated with cardiovascular diseases and malignant new growths of female reproductive organs at inhabitants of the Republic of Adygheya

    The distribution of polymorphisms G197/197A of the pro-inflammatory cytokine IL-17A gene is investigated by the SNP (single nucleotide polymorphism) method in ethnic groups (Russian and Adyghes) of the population of the Adygheya Republic: donors, patients with different variants and starting mechanisms of cardiovascular diseases and malignant new growths of female reproductive organs. The «normal» G197 allele IL-17A, which is most widespread in populations, is associated (Đ=0,011) with risk of development of peripheral atherosclerosis and tumoral progression at a cancer of a mammary gland (đ=0,026). Availability of polymorphism G197 of pro-inflammatory IL-17A can be used for inhabitants of the Adygheya Republic as a marker of system inflammatory reactions of the organism involved in pathogenesis of cardiovascular diseases and malignant new growths.

    Physiological assessment of fifth-former adaptation to learning activities on the basis of a vegetative component of heart rate variability

    This work studies adaptation of pupils to learning activity in the initial stage of training in the 5th form using the method of the mathematical analysis of heart rate variability. The authors reveal sexual distinctions of adaptation potentialities of an organism. It is shown that the main physiological mechanism of initial adaptation is the high tone of parasympathetic section of vegetative nervous system. The above-segmentary level of regulation serves as a marker of reserve possibilities of an organism in the considered age.

    Polymorphisms of angiotensinogen and receptor I of the angiotensinogen type in teenage groups

    Frequencies of Met235Thr and Thr174Met in the polymorphisms of a gene of AGT and A1166C of 2alleles of receptor I of the angiotensinogen-2 (AGT2R1) type associated with risk of development of cardiovascular diseases at the healthy surveyed teenagers living in Maikop (Adygheya Republic), are 0.410; 0.177; and 0.211, respectively. Frequency of Met235Thr in the polymorphisms of AGT gene exceeds similar indicators characteristic of the population in the Rostov region (0.179). No significant distinctions in frequency of Met235Thr of the polymorphisms of AGT gene in ethnic populations of the Adyghes, Russians and Armenians have been revealed.
