Cationic, hydrophobically associating polyacrylamide (PDA) was synthesized via the inverse miniemulsion polymerization in the presence of template. Dimethyloctane(2- acrylamidopropyl)ammoniumbromide (DOAB) was synthesized via quaternization reaction and used as the hydrophobic monomer. Polyacrylic acid (PAA) was used…
The membranes of sulfonated polyetheretherketone(SPEEK) doped with rare earth metal oxide nanometer cerium oxide (CeO2) were prepared for direct methanol fuel cell (DMFC) application, which was treated by parallel or perpendicular high magnetic field of 6 Teslas (T) at 100°C. The proton conductivity of membrane specim…
Thermo-oxidative degradation of graphite/epoxy composite laminates due to exposure to elevated temperatures was characterized using weight loss and short beam strength (SBS) reduction data. Test specimens obtained from 24-ply, unidirectional AS4/3501-6 graphite/epoxy laminates were subjected to 100, 150, 175, and 200°…
The article represents the attempt of social-philosophical analysis of public relations concepts of the contemporary researchers. The research results in the author's conclusions about the functional characteristics of public relations as social communication. The author considers social integration to be one of the m…
For the last twenty years is made the conversion of the Russian's consciousness. Through the aid of the west and Russian mass media went dethronement of our people ideals and imposition of the alien myths. Particularly active this was done during Gorbachev's perestroika and glasnost. As a result of myth's creation was…
In article is considered a problem of crisis of religious belief in the West European culture, the factors which have caused it - scientific revolution and philosophical concepts of New time, and also its display in art sphere.
Data on a domestic program complex «МВТУ» are short stated. The example of modeling of the technical system, illustrating high efficiency of a program complex is resulted.
In this article the author dwells the historical consciousness, its elements and sources of formation as well as the factors which influence the process of intercultural communications.

Acrylic polymers are widely used for fabricating pressure-sensitive adhesives (PSAs) with the inherent unique advantages of transparency and superior intrinsic adhesive properties over other polymer-based adhesives. In this study, we have developed and evaluated a method of obtaining by radical copolymerization PSAs f…
In the paper method for solving the direct problem for a differential equation of second order with variable coefficients is presented. This equation arises in the analysis of longitudinal oscillations of rods of variable rigidity on the basis of difference schemes. The way of determination of the law of change of You…
An analysis of mathematical model of the Process of granulation of the raw materials. Justified mode granulator
Top-priority national blueprint "Accessible & Comfortable Houseroom for Russian Citizens" is based on a federal purposive program "Home" & channeled into the solution of social problems which need concentration of material & administrative resources of the Federal Center & regional authorities. The article is about a…
Based on the use of the terms of set theory and mathematical logic and operations on them before the general approach to signal information about the equipment on the production and sharing of both types of information
The variants of answers are registered by cross (mark) in many test forms. The mark must be put on definite field of the test form. It is necessary tj employ the system of pattern recognition for corrective encoding this field. This system of pattern recognition must be stable against various distortions and interfere…
The new decision of a task of synthesis of set of frequencies for the purposes of synchronization of processes in automation is offered. The difference from now in use «grid» of set of frequencies with a constant step is, that the formation of set of grids or set of irregular meanings of frequencies is provided. It is…
The paper shows the results of research on relations between elements of production system of machine-building plants with individual and small-scale production from the position of process management. It specifies the main principles used when creating integrated systems of process planning and management.
The new design of a plane bearing with combined metal-polymeric surface differs from analogous models by ability to keep lubricant in the working zone, that considerably reduces a friction coefficient and life time of the bearing.
In this paper, pristine and oxidized multi-walled carbon nanotube (MWCNT)/poly(vinylidene fluoride) (PVDF) composites were prepared and the temperature dependence of some electrical properties of these composites were studied. It is found that the transition temperature (Tt), from positive temperature coefficient (PTC…
Visually-declarative language, N-Visual Language (NVL), intended for projection of the software of information systems: database structure and a code realising business logic, is in-process introduced
