The analysis of ethnic migration at the regional level, more detail is given on the example of Stavropol territory.

In the territory of Stavropol, integumentary loams have broad, almost universal distribution and lie on various elements of a relief. Article is devoted to questions of wrong opinion of local geologists and authoritative scientists of Russia, which carry this soil to diluvial educations. Based on new achievements of paleogeography and paleoclimatology proved the Genesis of Aeolian loams and their belonging to single loess formations in the South of Russia. Questions, extremely important for an explanation of genesis of integumentary loams are considered: what geological agent how, from where and, the main thing, under what physiographic conditions primary material for integumentary loams of Stavropol could deliver? The geological section of districts of Stavropol from the prospecting reports showing against diluvial genesis of integumentary loams of the city. Analyzed assessment of the Genesis of covering loams as the following extracts from reports and of the city, planning regulations and the findings based paleogeographic environment of their accumulation.

This article presents the theoretical foundations (the concept of tectonic activity and the concept of the mechanism of formation of the structures of the central type and their interpretation, with an assignment of zones of compression, stretching, geodynamic centers and nodal points). It provides the specific results of interpretation of topographic maps and satellite images with detection of structures of the central type (SCT) and lineaments, the interpretation of SCT with an assignment of possible zones of abnormal high pressures on the territory of the Krupskaya area of the Azov Kuban cavity, on the Kamyshovoe and the Ravninnoe fields in the Kumo-Manych cavity, and specifically identified zones of abnormal high pressures on the Kasatkinskaya area at the junction of the Caspian cavity and the Karpinski ridge. For the first time the paper provides not only the results of decryption of aerial and satellite images and topographic maps, but also the method of their interpretation, with an assignment of regions of interference of zones of stretching, compression (prospective zones of abnormal high pressures) and nodal points or zones of subver-tical destruction, that are promising to contain oil and gas, and seismicity.

The region of Caucasian Mineral Waters is one of the oldest and leading Russian recreation areas, on which territory there are a variety of recreational resources: hydromin-eral, mud, etc. This contributed to the formation of Caucasian Mineral Waters region as the largest sanatorium complex of the country. The article discusses about one of the significant historical stages of development of the resort region of Caucasian Mineral Waters - 1920 of the 20-th century. The peculiarities of the development of sanatorium-resort complex of the region during the study years were identify in connection with events in the country and government regulations. It is shown how to expand the network of sanatoriums and material and technical base, improved resort infrastructure, developing recreational activities and occurred the formation of new Spa treatment, and also presents information about dynamics of holidaymakers during the period.

Fundamental research of Quaternary glaciations in the West Caucasus conducted in the 20th century between 1940's and 1960's. For example the Teberda river valley glaciation models of different authors were represented. Research, presently conducted in the Gandaray river valley allowed to clarify the steps of formation of recessional moraines of upper quaternary glaciations and for the first time to create a paleogeographic model of transformation of the altitudinal geobotanical zones for each stage of glacial retreat. Modern tendencies in the dynamics of glaciers and changes in biotic components of the regions are linked to global warming and factors of human activities.

Spectrum and kinetics of dibromdibenzotiofen phosphorescence in n- hexanes at 77 K have been studied. It has been shown that the visible multiplet structure of phosphorescence spectrum is determined of the superposition of spectra emitted by different types of centers. The existence of the three types of radiating centers is supported by different efficiency of quenching their phosphorescence in the presence of acenaphthene, which is energy acceptor triplet excitations and is supported by the dependence of the intensity distribution between the components of the multiplet on the exitation method.

In this paper, we carried out the XRD results and 3D structural models of short-range order of amorphous cellulose obtained by ball milling of microcrystalline cellulose. The amorphous cellulose has the well-reproducible effect of influence of ozone treatment on its proton conductivity, which allows to use this material as a gas sensor. Calculation of the quantitative characteristics of the short-range order (radii of coordination spheres and their dispersions, coordination numbers) of amorphous cellulose was carried out from distribution pair functions curve by using the Finback-Warren method. The space atoms configurations was carried out by Debye method. After that, the models were distorted by converting into packages disoriented relative to each other layers. The X-Ray diffraction patterns were calculated for 3D models and compared with experimental curves.

Iscusses empirical functions that were defined when-blajenno, for example, based on some measurements of the observed process or phenomena obtained in the experiment. Such functions are considered to be summable in a certain area of observation, but not differencethe get adequate in the usual sense. Difficulties associated with the use of conventional derivatives for the analysis of such functional dependencies require the development of such methods of functional analysis which would operirovat-whether the so-called generalized derivatives (also operators of generalized differentiation). The corresponding apparatus was proposed by the authors earlier is applied to solve differential equations in case of discrepancy and based on the performance of the studied functions by singular integrals. Within the present work from the suggested above approach is extended to the case when the integrals in IP-initial representations of functions have the form of the Stieltjes integral (Lebesgue - Stieltjes). In a number of application tasks desired functions as the initial assumptions required the need to present in the form of the Stieltjes integral. A similar situation can occur in the theory of potentials and the theoretical physics problems that use inte-integral operators of potential type. This approach significantly extended the content of the unit of approximation of functions, giving it greater efficiency and clarity in those tasks when you have to «construct» the model of functional dependence according to rough data (also in conditions of a priori uncertainty). Thus, the computational schemes that are associated with practical carrying out-she described the method in applications in some cases can be much simpler and more eficient algorithms that are required for the implementation of integral representations of functions based on singular integrals. The work performed in the construction and justiication of the computational method, an example illustrating possible applications of the presented Noi the theory of representation of empirical functions.

We studied the changes of the component composition and physic-chemical parameters of the nutrient medium before and after cultivation of bifidobacteria. Developed methods for purification of spent growth media from products of metabolism and tested different methods to restore nutrient media for regeneration. The data obtained indicate the possibility of restoring the original properties of nutrient mediums by restoring its neutral reaction. The most effective are physical and chemical methods of regeneration using semi-permeable membranes. Regenerated nutrient medium can be used for microbiological and biochemical industries. These studies allow us to make the process of using mediums cost effective because it will significantly reduce the cost of preparation of the nutrient medium and its disposal by the possibility of increasing the usage frequency of nutrient medium.

Currently, the importance of vitamin D for human body is determined not only by ability to regulate calcium and phosphorus metabolism, processes of osteogenesis and maturation of the skeleton, but also affects the immune system and psychomotor development. The aim of the study was to investigate the effect of high-protein milk product, fortified with calcium and vitamin D in different doses of mineral metabolism in laboratory animals in childhood and adolescence. A biochemical study of 72 Wistar rats in different periods of postnatal ontogenesis. Mineral metabolism was evaluated by content calcidiol, calcium, inorganic phosphorus, calcium-phosphorus ratio, total protein and activity of alkaline phosphatase in serum. It was found that rats not treated milk product is insufficient vitamin D. the necessity of selecting the optimal dose for targeted prevention of hypovitaminosis D. It was shown that rats treated with a milk product enriched with calcium, protein and a therapeutic dose of vitamin D, metabolic disorders was accompanied by a pronounced and prolonged biochemical syndrome, which is not observed in the other groups.

A study of daily dynamics of transaminases in the blood under the influence of alcoholic beverages in rats. It was found that the treated rats as alcohol and non-alcoholic beer, the daily dynamics of the content and alanine aminotransferase, aspartate aminotransferase and disorganized even at ordinary light mode and is particularly aggravated during shift illumination mode. These animals mounted significantly higher values aspartate levels in the blood for days, compared with data for control animals throughout the experiment.

Theoretical justification of application of new physical approach to research of structure of lifeless and alive objects - a method of fractal geometry is given. It is shown that the brain of animals is a product of deeply nonequilibrium processes, and, therefore, object with fractional dimension. The technique of determination of fractal dimension (D) studied objects is offered. Results of the fractal analysis of computer images of microphotographs of the frontal cuts of supraoptic (SO) and are presented paraventricular (PV) nuclei of a hypothalamus of a cat. On the basis of the obtained data it is established that 1) the studied groups of neurones of area of each core have pronounced monofractal structure with different fractal dimensions; 2) therefore, each core in general is a multifractal.

The article describes the results of a survey of 134 adolescent boys, carried out with the aim of studying modality indicators of the state of cerebral hemodynamics teenagers with beer alcoholism. We found a significant circulatory disorders in the brain in adolescents depending on the day of drinking beer. As indicators of estimating cerebral hemodynamics in teenagers with beer alcoholism noted: the increase in pulse blood and vasodilatation; the presence of spasm of peripheral vessels; change the state of tone and elasticity of blood vessels; violation of vascular tone of the initial part of the microvasculature, arterioles and precapillary's; violation of the venous outflow. These indicators can be used to assess the toxic effect of beer on the physiology of adolescents and install the latest days of consumption.
