STUDY OF THE ABNORMAL WEATHER CONDITIONS INFLUENCE ON THE HEART RATE VARIABILITY OF MEDICAL STUDENTS
Botoeva N.K., Khetagurova L.G.
The influence of the meteorological factors on the state of autonomic regulation according to the heart rate variability of the medical students under the conditions of abnormally warm December 2010 was studied compared to the same period in 2008. The study revealed the growth of the regulatory systems tensity that can be regarded as mobilization of the adaptive mechanisms with the aim of maintaining homeostasis in the conditions of the abnormal environmental influence.

THE ANALYSIS OF TOXIC INFLUENCE OF HEAVY METALS SALTS ON THE BASIC MEDICOBIOLOGICAL PARAMETERS OF HEALTH IN EXPERIMENT AND CLINICS
Dzugkoeva F.S., Khetagurova L.G., Chopikashvili L.V., Kasokhov A.B., Dzugkoev S.G.
The salts of heavy metals induce formation of oxygen active forms initiating lipoperoxidation (LPO) in erythrocyte and renal tissues and infringement of superoxide-dismutase and catalyses activity. The secondary products of LPO cause disfunction of an endothelium and development of toxic angio- and nephropathy. The children, living in ecologically unsuccessful areas of Vladikavkaz, have oppression of immune reactance, decrease in the maintenance antiinflammatory cytokines and increase in proinflammatory concentration, it leads to an exacerbation of a bronchial asthma. Heavy metals salts of are the reason of the genovariations leading to the infringement of genital function of women of reproductive age and congenital developmental anomalies of newborns. Thus prooxidanst render cytotoxic action at a molecular-genetic level, and break neurohumoral mechanisms of regulation visceral systems, promoting formation of the special form of pathological process – vicious circle.

DISASTROUS EVENTS NEAR THE VILLAGE OF BULUNGU AS REFLECTION OF PECULIARITIES AND TRENDS OF DEBRIS FLOW PROCESS DEVELOPMENTS
Zaporozhchenko E.V., Kamenev N.S.
Taking example the debris flow on July, 20, 2010, which (for a third time during the last 15 years) brought about destruction in the village of Bulungu, causes and trends of the increase in debris flow risks and dangers, caused by degradation of glaciation and relevant changes in the situation in peri- glacial and glacial zones of the Northern slope of the Main Caucasus Ridge and also forecast for the near-term outlook in the 21 century, are analyzed.

MINERALOGY OF BROWN MOUNTAIN FOREST SOILS ON GRANODIORITES IN THE RUSSIAN FAR EAST SOUTH
The final research data on mineralogical composition of brown forest soils, formed on biotite granodiorites in the low relief conditions of the Russian Far East south are discussed. Specifics of soil texture and its physical and chemical composition are described. Heavy minerals, revealed with panning in soil horizons, are characterized. The paper presents schemes of transformation of primary rock-forming minerals into secondary clay minerals, found in soil with thermal analysis and X-ray crystallography.

ON THE RIVERS DRAIN FED WITH GLACIERS AFFECT ON THE CLIMATE WARMING
Kamalov B.A., Soliev E.A.
The article considers the glacier-fed rivers drain during the global climate warming. The Sokh river having the big glacier-fed volume till the middle of the seventies experienced a low water period followed by a high water period during the global warming. Correspondently the glacier area increased in the cold period and decreased during warming, the latter can lead to the considerable negative drain trend and its variation growth, the phenomenon being observed for the Isfairam river. The average long-term parameters values of the early drain distribution δ = WVII-IX/WIII-VI determined by a glacier drain value in the average long-term drain while the annual values of δ mainly precipitations sum functions for the hydrological year. The conclusion shows the complications possibility for the irrigated territories water supply due to the glaciers degradation.

NEW MINING TECHNOLOGIES: THEORY AND PRACTICE
Evdokimov S.I., Artyomov S.V., Panshin A.M.
To increase the technological factors of the gold-containing enrichment at the Olimpiadinsky deposit and the copper ores at the Urupsky deposit the stream flotation scheme and the column flotation equipment for the rough concentrate extraction in the 2nd flotation jet were used. During the column flotation the vapor-aerial mixture with foamier and oleic acid was used as a gas phase being supplied to the column through the pneumonic hydraulic diffuser-confussor aerator. The non-empiric method for the vapor expenditure calculation needed for the vapor aerial flotation was developed.

A NEW STAGE IN THE NATALKINSKY GOLD ORE DEPOSIT DEVELOPMENT
Kazimirov M.P., Solodenko A.A.
The laboratory tests of the Natalkinsky deposit ore flotation were carried out resulting in the determination of the main ore enrichment parameters such as the optimal size and the import floto reagents use efficiency. Gold extraction is expected to reach not less than 90% using the gravitation flotation technology in the industrial conditions.

THE INWASHING TECHNOLOGY OF THE CASCADE TYPE STORAGE POND FOR THE WASTE OF THE MINING INDUSTRY
Lolaev A.B., Akopov A.P., Oganesian A.Kh., Sumin M.N.
The object of research is the tailing dump, representing one of the most adverse kinds of stores – the cascade type, with the difference of more than 20 m in water levels in the first and second ponds. The optimization of the subsequent inwash technology for tailing dump has been executed by the following criteria: the stability of the dam; the maximum use of the tailing dump capacity; decrease in material and financial expenses for operation; industrial and environmental safety. Variants of inwashing and warehousing of tails have been investigated by means of physical and mathematical modeling. On the basis of the analysis of mathematical calculations and the results of model tests during in-situ approbations the optimum parameters of the inwash technology of the dam have been defined.
