Application of regular representation of a integrodifferential singularly perturbed system equations for their numerical solution
In this paper we give a regular representation of a boundary value problem for a singularly perturbed Fredholm type integrodifferential second order equation in the perturbed Fredholm type integral equation form. Two different successive approximation methods are determined. It is shown how the regular representation of singularly perturbed equations allows us to construct efficient methods for solving differential.

UmovPoynting vector for the electric and magnetic dipole moments
This paper examines the properties of UmovPoynting vector for the electromagnetic field of an arbitrary varying electric and magnetic dipole. It is shown that in the near zone, at distances comparable with the typical wave length, the direction of the energy flow vector is not radial. The derived formulae in the far zone asymptotically approach the known expressions for dipole radiation. Special cases of linearly varying and precessing dipole moment are considered.

The paper provides data on the karyofund features of populations Chironomus nuditarsis (Chironomidae, Diptera) from plains, foothills and mountains of the Central Caucasus (KabardinoBalkarian Republic). We have found 11 banding sequences – two in the arms À (ndt A1, ndt A3), Â (ndt B1, ndt B2), F (ndt F1, ndt F2) and G (ndt G1, ndt G2) and one in the arms C, D and E – ndt C1, ndt D1, ndt E1. Ten of them have already been known, and one – ndt F2 (17fm  19ag) is endemic, it is described for the species for the first time, but had previously been identified in Ch. plumosus.

Condition of cardiovascular system and neurophysiological status of students attending the football class
The paper discusses mechanisms of regulatoradaptive possibilities of cardiovascular system of the students who attend the football class. Data on heart rate variability were used to determine the regulatoradaptive status of students. Three groups of students who attended the football class were revealed: with high degree of adaptation (47%), with pressure of regulator mechanisms (20%) and with unsatisfactory adaptation (33%). Features of the neurophysiological status are defined within each group.

Pathophysiological role and the prognostic importance of the angiotensinogen (AGT) gene M235T polymorphism at illnesses of a heart continuum
An analysis is made of data of the international ethnogenetic researches carried out in 1995 through 2010 by frequency and association of M235T polymorphism of AGT in patients with risk of development of cardiovascular diseases using HuGENet data. In 12 % of the researches conducted in different ethnic populations, significant increase of frequency of ̀235̉ polymorphism of AGT in groups of patients with cardiovascular diseases is observed. This allows us to regard it as a prognostic significant criterion for risk of development of illnesses of a heart continuum. We consider it expedient to study distribution and associations of 235̉ polymorphism of AGT gene in groups of patients with cardiovascular diseases in different regions of the world taking into account ethnic features of surveyed contingents of the population.

Biological features of a leaf of Spiraea specimen
The paper provides the results of studying morphological features variability of the leaf of Spiraea L. specimen. It is established that the majority of the leaf features has high degree of variability; the greatest variation factor of the leaf size is at S. japonica `Macrophylla`. The results of research of epidermis and leaf stomata of Spiraea genus are given. The maximum general factor of features variation was observed at Spiraea x bumalda Pall., the average level of features variability at Spiraea alba Du Roi. and S. betulifolia Pall.

The generic and zoogeographical analysis of the fauna of scarab beetles (Scarabaeoidea, Coleoptera) in the Adygheya Republic
The paper presents the results of generic analysis of fauna and areal data of beetle species of the superfamily Scarabaeoidea occurring in the territory of Adygheya. The generic analysis of Adygheya scarab beetle fauna allows the authors to allocate 77 genera belonging to 5 families and 121 species belonging to them, of which 3 species are marked for the first time in this study area. The Caucasian species make up 16% of the fauna under study.

Muscle activity when doing a backheel by highlyskilled female judoists
The 2D and 3D video analysis was used to examine doing a backheel, one of the basic techniques in judo. Female judoists – members of the youth national team of the Russian Federation participated in experiment. It has been established that doing the backheel is accompanied by the greatest changes in relative length of muscle, as well as by the highest speed of contraction of the following muscles: right m. adductor longus, caput breve left m. biceps brachii, left and right m. biceps femoris, right m. latissimus dorsi, right m. obliquus externus abdominis, right m. rectus femoris, right m. sartorius, left and right m. gastrocnemius.

Some aspects of people's awareness of foods produced from genetically modified organisms
The paper provides a brief overview of the different points of view on foods produced from genetically modified organisms (GMO), on regulation of their production and on problems of people’s awareness of this food. The results of the author’s pilot interview on actual questions related to foods produced from GMO are considered. It was established that citizens of the region, despite their sufficient high education, are poor informed about foods produced from GMO. The author points to the key sources of information about foods from GMO and about their low efficiency. The advices to raise people’s awareness are given. Recommendations are aso given for the regional authorities concerning the transgenic products production and the creation of GMO free zones.

Graphanalytical model of regulation regional transport
The paper provides a model of formation of optimum structure of a regional transport management based on a graphanalytical method. The model’s prospects are related to the analysis and a choice of priorities at formation of various schemes of regulation of the regional transport complex. The model can be used to make the comparative analysis of already functioning models of regulation and to choose the best among them. The model develops ideas of the cognitive approach at the solution of the poorly structured problems, developed at the Institute of Problems of Management of the Russian Academy of Sciences.

Increase of efficiency of vehicle braking on slippery roads
The paper is dedicated to the questions of increasing efficiency of vehicle braking on slippery roads owing to strengthening of coupling properties of a wheel with a road covering. This is achieved by creation of shortterm artificial increase in a roughness of a racetrack of the tire on all its length and of a road surface at emergency braking of a vehicle.
