THE SLOWED-DOWN FLUORESCENCE AS THE METHOD OF RESEARCH OF CHANGE OF AGROCHEMICAL INDICATORS OF THE SOIL COVER AT HEAT TREATMENT (ON THE EXAMPLE OF THE STEPPE ZONE OF ORENBURG OBLAST) ^{[№ 10 ' 2015]}
On the basis of a pilot study the method of research of change of agrochemical indicators of a soil cover of the Steppe zone of Orenburg Oblast at its heat treatment is offered. Sampling of soils when carrying out experiments was carried out by an envelope method on different profiles of the horizons, tests of soils were exposed to heat treatment at temperatures from 200 to 800 °C within 30 min. and were analyzed on installation for registration of the slowed-down fluorescence. Experimental groups of soils were also exposed to the chemical analysis on the maintenance of the main agrochemical indicators. The made experiments showed that for all studied types of soils irrespective of the modes of temperature influence the exponential law of attenuation of fluorescence is carried out, but all types of soils are various on an indicator of intensity of a luminescence and coefficient of attenuation. The soil which is thermally processed in the range from 400 to 600 °C is characterized by the raised maintenance of mobile forms of phosphorus and potassium, and it рН increases with temperature increase. In work the algorithm of technology of restoration of fertility of the soil at introduction of the calcinated soil as fertilizer is presented, taking into account рН and the maintenance of nutritious elements in it on the basis of which it is possible to carry out melioration and recultivation of the soils broken as a result of an industrial erosion.

FOREIGN STUDENTS IN RUSSIA: CONDITIONS AND BARRIERS OF INTEGRATION ^{[№ 4 ' 2010]}
The results of empirical research conducted among foreign students in institutes of higher education of Nizhny Novgorod are given in this article. The analysis of data allows revealing conditions and barriers of foreigners’ integration into new social-cultural reality. An aspiration of a foreigner to keep cultural identity is balanced with a wish to connect own future with Russia, but weak adaptive activity — with comfort feeling in Russian region.

PARAMETER OF DAMAGEABILITY AND CLUSTER MECHANISM OF STEEL HYDROGEN BRITTLENESS ^{[№ 2 ' 2006]}
The cluster mechanism peculiarities of brittle destruction of the system: steel – hydrogen in conditions of transient diffusion of chemical impurity are researched on the base of law of hydrogen damageability. It was distinguished that metal-hydrogen clusters are slim disks with diameter from five to forty Angstroem units. Pictures of clusters zones on steel breakings at abruption and pure shear were got. The analysis of existing conceptions of chemical impurity introduction clusterization was done here. The new results are basis of dynamic active conditions of metal-hydrogen clusters with hyperelastic features.

SYNERGETIC CONCEPTION OF HYDROGEN DAMAGEABILITY OF METALS AND METALS (STAGES OF DEVELOPMENT AND PERSPECTIVES) ^{[№ 1 ' 2006]}
It is shown in the article that synergetic approach to the phenomenon of hydrogen materials fragility, originated at the contact with damp hydric sulphide gas, allowed getting original scientific results, working out theory of hydrogen fragility and solving actual practical tasks of diagnostics and increase of steel hydrogen resistance. A new concept of fractal energy hierarchy of structural material conditions, which has an applied and fundamental meaning and opens opportunities of energy parameterization of microstructures were introduced in physics of durability and materials science.

DISSIPATIVE TRANSFORMATIONS OF THIN STEEL`S MICROSTRUCTURES IN CONDITIONS HYDROGEN`S DIFFUSIVE TRANSFER ^{[№ 10 ' 2005]}
The article is devoted to researches of open system steel - hydrogen in conditions of diffusive transfer of an embedding impurity. The method of x-ray diffraction in situ is used during electrochemical hydrogenation of membranes and electronic microscopy for studying transformations of defective metal structure. Repeatability of processes of accumulation and discharge of micropressure with reorganization of defective structure in ОКР are established, migration of borders, formation of deformation relief, a substructure and porosity are also examined. The initial structure of steel influences on the kinetics of transformations.

MATHEMATICAL MODELLING OF RADIOACTIVE NUCLIDE MIGRATION IN SOIL – VEGETATIVE COMPLEXES OF ORENBURZHYE ^{[№ 9 ' 2005]}
Research of migration of elements on a soil structure is one of the important approaches to studying of anthropogenous influence on vegetation. Radioactive nuclide migration on a ground structure occurs due to moving of soil particles, which form its structure, due to movement of the soil moisture, containing soluble and colloidal their forms. Sorption of heavy metals is carried out due to two processes fast – exchange and slow not exchange.

CORROSION PROPERTIES OF STEEL WITH CELLULAR-POLYGONAL SUBSTRUCTURE ^{[№ 9 ' 2005]}
It is experimentally established that the two-level cellular-polygonal substructure received on technology of explosive hardening and thermal processing, in one and a half – three times improves parameters of corrosion resistance and water resistance of steel in hydrogen-sulphidous medium. The mechanism of increase of thermodynamic stability of metal is discussed.
