Bondarenko V.A. THE UNIVERSITY DEVELOPMENT IN THE CONTEXT OF THE SOCIO-CULTURAL DYNAMICS OF THE COUNTRY AND REGION In this article the necessity of the broadening of the regional university regarding the perspective development of all the branches of national economy is well-grounded. The author uses the experience of the US regional universities where the educational programs are adapted to the concrete economic and industrial needs. Successes achieved by Orenburg State University in this direction are also summed up in the article. The author maps out concrete measures, and lays down a program of the further perspective of the fundamental science of Orenburg region on the basis of the technological progress of the regional national economy.
Kiryakova A.V. VALUE CONCEPTION OF THE PERSON ORIENTATION IN THE WORLD OF EDUCATION The notion of value is a key-word in axiology as a theory of values. However it is also very important in education while the orientation of a person in the world at large is dependant on his/her orientation in the world of values.
Zelenskaya L.L. CULTURAL ASPECTS OF EDUCATION The author analyses the historical background and the current situation in higher education in Russia. For many decades education had to meet the goals and needs of the ruling party. Now that Russia has undergone drastic changes education is facing new problems including humanization, differentiation, individualization and integration. Because of these new concerns there is a problem of creating a new university environment since it is impossible to educate new generations of professionals with a different human mentality within the old system. A university student should be "placed" in the crossroads of educational, scientific and cultural segments of the new university environment.

Kucherenko M.G. BROWNIAN RANDOM WALKS AND ALIKE ELECTRONIC EXCITATIONS ANNIHILATION KINETICS A formal description of annihilation kinetics of alike quasi-particles is developed in the work on the basis of methods of Brownian motion theory. The probability of particle survival for given realization of its Wiener's path is determined. Observed time dependence of survival probability are presented as statistical average of different the random walk. A variant of kinetics description with the account of the dispersion of volume is considered. Small impact on the asymptotic stage of kinetics is analysed. The conclusion of another authors about the fluctuation stage of reaction kinetics is confirmed.
Stryapkov A.V., Podosenov D.E., Koshchei E.V. INVESTIGATION OF JOINT HYDROLYSIS OF CERIUM (III) WITH FERRUM (III) Precipitation composition produced by joint hydrolisis precipitating of cerium(III) with ferrum(III) from sulfate solutions under various pH has been studied. It is found that bond strength of cerium(III) with precipitation is great enough and only ions presented in the solution are recovered with cationite KУ-2х8. The mechanism of coprecipitating included acidic properties of joint ion strengthening and formation of covalent bonds is suggested.

Fot A.P. DYNAMIC PROPERTIES OF MULTIPOSITIONAL PROVING EQUIPMENT The article considers one of the aspects of multipositional equipment designing regarding interdependence of separate units (outfits and mechanisms) in the given equipment operation and current dynamic processes. Disrespect of interdependence effect may cause negative results and unnecessary expenditure for the elimination of consequences through the designer's mistake. Widely spread computer technologies based upon mathematical modeling of the given structure and computer experiment eliminate labour input of multipositional equipment calculations. This method has been first applied by the author in the evaluation of dynamic properties of multipositional tearing machines (MTM) intended for corrosion and mechanical testing of material specimen. The calculation results of machine parameters according to the proposed dynamic model showed that the dynamic model MTM in comparison with the simplified static model gives much more information about the load changes in a specimen. The machine design rationality as well as the expediency of MTM usage in corrosion and mechanical testing of materials have been testified.
Rassokha V.I. SYSTEMATIC MAINTENANCE OF FATIGUE BENCH-TESTS OF VEHICLE FRAME METAL CONSTRUCTION UNITS The loading scheme for fatigue bench-tests of longeron section junction unit and cross-beam site of vehicle welded frame has been developed. The expressions for the size definition of unit elements as well as the parameters of testing unit strength loader, which provides the parameters similarity of fatigue destruction process with the operational one, have been inferred.

He shows the main stages of the development of the science of construction, its role and place in the scientific and technological progress. Social, technical and aesthetic aspects presented by the author show general rules of human activity in the sphere of architecture and construction in the forthcoming century.
Shevelenko V.D., Shevelenko D.V, Kvitek E.V. FILTRATION OF MEASURING SIGNALS BY MEANS OF FORMING THE QUOTIENT SUMS OF FURJE ROWS This article describes the spectral method of filtration of measuring signals founded on the possibility to reduce (to cancel) the volumes of transformations over a signal by means of transition from the basis of harmonic functions to the basis in the form of Dirichle nucleus. Correlations providing the realisation of the filtre property of orthorationing basis by means of the reproducing the Dirichle nucleus in the form of the amplitude-modulated oscillation were received. The authors show the possibility of the practical realisation of the filtre device and assess its errors.
Polyshchuk V., Sagitov R. FEATURES OF THE AUGER PRESSING GEAR OIL PRESS In the present article the mathematical model of flow of an oil-yielding material in the channel auger oil press is considered. The introduced model allows to define four arguments of effect - productivity of the pressing gear, power of forces of useful resistance, power consumption of process of squeezing and gain which is operational on end-effectors (axial force or a torque). The described mathematical model after its verification can be utilised for optimization of pressing gears at the stage of initial designing oil presses.
