ASSESSMENT OF SOIL POLLUTION IN THE ZONE OF INFLUENCE OF METALLURGICAL ENTERPRISES [№ 9 ' 2017]
The total contents of heavy metals in soils selected in the zone of influence of Karabashmed CJSC, Satkinsky Iron-smelting Plant JSC and Uchalinsky Ore Mining and Processing Plant OJSC were analyzed. The excess of the standards for all metals except manganese has been established. The phytoremediation method — accumulation of heavy metals from soil by plants was tested on the investigated soils. It is shown that after growing plants in the soils, the content of iron, zinc and copper decreased. Assessment of soil contamination degree using the concentration coefficient showed that in the studied soils before planting the total amount of most metals is within the limits of natural fluctuation. A weak level of soil contamination with cadmium has been established (Uchaly), moderate contamination with copper (Uchaly) and zinc (Karabash), heavy pollution with cadmium and copper (Karabash). As a result of the use of phytoremediation technology, the concentration coefficients for iron, zinc and copper have significantly decreased. And according to the content of copper, Uchalv’s soil passed from the category of moderate pollution to the category of low pollution. To estimate the multielement influence the levels of heavy metal contamination were calculated using the Saet’s index and the index proposed by Yu.N. Vodyanitsky, taking into account the different toxicity of heavy elements and based on the average geometric parameters. It is shown that the use of phytoremediation technology decreases the level of total contamination of soils with heavy metals.

THE MASK OF PROVINCIAL IN THE STORIES BY EVG. POPOV'S 1970–80 [№ 11 ' 2012]
In the article for the first time investigating the specificity of creation provincialities discourse in collection stories "Merry-making of Russian" by means of author's mask. The author's mask is considered as stylistically marked narrative device, and as the mean with the help of which the author presents himself in the text.

VIRTUAL COMPONENT OF SPIRITUAL EXISTENCE OF SOCIETY [№ 7 ' 2007]
The phenomenon of virtual reality as ideal and wider than spiritual world of a human being where the subject transforms the content of substantial, social or psychological realities is regarded in this article. In his work the author rests upon workings in the sphere of mentality, consciousness, spiritual and ideal of such researchers as N. Vinner, D.I. Dubrovsky, N.I. Zhukov, E.V. Ilienkov, N.N. Moiseev, V.V. Orlov, Z Freud, K.G. Yung, at the same time making alterations at reading of general philosophical and scientific categories by them.

OPTIMAL SPEED MODELING OF THE OIL DISPLACEMENT AND OIL SATURATION AROUND THE INJECTION POINT [№ 2 ' 2005]
Dependence of the residual oil content on the filtering rate is studied in the statistical formation model, filtering process and water-oil displacement. Its nonmonotonic dependence is cleared up, optimal filtering speed for a minimal residual oil content is rated. Residual oil content fields around the injection point are constructed by the computational modeling. Their nonmonotonic dependence is from a distance to the well. This is necessary to get into account while projecting the seam pressure support system.

TO THE PROBLEM OF AUTOMATED MANAGEMENT PROJECTING AND SUBSYSTEMS MODELING OF MAINTENANCE OF SEAM PRESSURE ASUTP OF PETROLEUM PRODUCTION [№ 12 ' 2004]
Questions of projecting of automated management subsystem with technological conditions of liquid pumping for maintenance of seam pressure (PPD) as a part of petroleum production ASUTP, were regarded in this article. Functional, logical and topological models of adaptive SAU of PPD system with etalon model were worked up. The analysis of model management system in linear approximation with account of decomposition on local models was passed here.
