In conditions of an aggravation of competitive struggle with the foreign companies the production of a question about determining influence of innovation development of the domestic enterprises on final results of their activity becomes especially urgent. The character of influence of the investments in innovation sph…
Ethylene-propylene-diene-graft-polystyrene (EPDM-g-PS) copolymers were synthesized to obtain different structures of graft copolymers with different graft lengths and graft densities. The structure of synthesized EPDM-g-PS copolymers was characterized by gel permeation chromatography (GPC) and by Fourier transforms in…
The waterborne polyurethane (WPU) dispersions from the reaction of cycloaliphatic diisocyanates [4,4’-methylenebis(cyclohexyl isocyanate) (H12MDI) and isophorone diisocyanate (IPDI)] and polyethylene glycol (PEG) with various molecular lengths were synthesized using our modified acetone process. Differetial scanning c…
The results of researching function of cost of welded lap joints are presented. Two lap joints are examined, working both on a tension, and on a squeezing: plate with a plane and corners with a plane. The dependences are deduced for designing welded lap joints with minimal cost. The results of researches can be useful…
The review of methods of calculation and optimization of die forging processes is submitted. The scheme of direct and inverse mathematical simulation of metal forming and methods realization of calculation are considered. On concrete examples the principles and methods of the calculation of optimum original and interm…
In clause directions of perfection of a technique of definition of a complex estimation of a condition of the built up territories are considered. Procedure of a complex estimation includes calculation of ecological, economic, social parameters and association of the received values in a uniform parameter. For the acc…
The model that allows forecasting of particle size distribution when milling magnetic powder in the magnetovibrating layer using beater mill was proposed. Model arguments are initial grain size distribution, milling time and variable magnetic field gradient. The correlation of model with experimental results is shown.
The article covers the problem of correlation between intellect and aptitude for empathy in terms of the individual style of economists and physicists' to be activities. The influence of typological peculiarities of students on the efficiency of their professional activity is registered on the basis of the results of…
Presented results of the diffusion processes research in alloyed Fe-base powdered steel at lowtemperature diffusion saturation by nitrogen and carbon. There was installed mechanism of the shaping structured-phase composition diffusion layer depending on contentses alloyed elements and spread of time processing.
In article is described the mathematical model of form-building curvilinear profile for polish. The model take into account nonlinear operators of transformation and nonstationary accidental influences.
The role of civil society is changing nowadays under the pressure of global problems, spread of national borders and constantly growing process of informatisation. It is not only linked to the state but overcomes the state frontiers to solve up-to-date problems of mankind. Thus civil society becomes global that can be…
Corporation human resources consist of general, private and special components. Function of corporation human resources have to based on scientific management and conform interests of corporation and personal. Reproduction of special human resources depending on level of social responsibility and optimal development c…
Results of research of properties of the polycomponental powder materials formed of separate components in factorial space of "mixing - property" on the flat simplex diagram are submitted. Thus on the basis of the general principles of construction of information-analytical system (IAS) the decision of individual prob…
It was suggested a new conception of identification of wear intensity of lubricated steel friction surfaces by size and distribut6ion of micromechanical characteristics in thin undersurface level, deformated by friction. Suggested criterion characterize antiwear features of lubrication oils.
In our work we form the principles of organizational and technological design of robotized technological complexes for manufacturing large-scale, non-rigid, spatial structures with great number of short-length welding joints. The algorithm of design process is also considered.
This article provides the analysis of the concept of «sign», gives an overview of main characteristics of «semiosphere», pointes out the ground of misunderstanding of cross-cultural adds; detenmines the types of signes and thein connection.
In the accepted model of formation of chip we were based on hydrodynamical laws, and also on reological appearances taking place during relative movement of particles of the body. Theoretical expressions for definition of pressure on a true rake of the tool were obtained.
The article is devoted to transformation of a course policy of Bank of Russia and introduction of "a basket of currencies " consisting of Euro and US dollar. Since February, 2005 the currency basket is one of major factors of a monetary and credit policy of Bank of Russia influencing on formation of a real rouble exch…

By using mercaptosuccinic acid-cerium(IV) sulfate and mercaptosuccinic acid-KMnO4 redox systems in acid aqueous medium, the polymerization of acrylamide monomer was performed at room temperatures. Water soluble acrylamide polymers which contain mercaptosuccinic acid end-groups were synthesized. The dependence of polym…
