In this article the basic parameters required for residual life assessment and life extension of the technical condition of water or long operated facilities. Inlet water or prolonged use many facilities design elements out of order it - complete destruction of concrete structures water conveyance structures, the formation of defects, normal operational performance of the design water conveyance facilities, such as violation of butt joints, as well as the destruction of the individual elements of the structure, etc. During the development of methods for extending the life cycle of water conveyance structures are obtained by the use of impervious geotextile cover that make for a correct evaluation of residual life of structures may extend its operational life cycle. The question arises of the need for correct and timely manner and to assess the remaining amount of the carrying capacity of water conveyance structures, to evaluate the technical condition and extend its life cycle. To do this, we can apply the proposed impervious geotextile cover.

  In many applications of profiling cutting tool, define the envelope surface collection. Along with the classic approach to the definition of the envelope of the recently used and new. So, if your family schedule projected two-dimensional surfaces in space R4, then get some three dimensional hypersurface Σ. Kriminanta this is the envelope of family of surfaces. The authors study the surface Σ when setting its parametric equations and equation in implicit form held in the works.  Found some new properties of such surfaces. Due to the fact that when profiling cutting tool set family of surfaces, coordinate transformation equations, an important task is the study received thus hypersurface. On the basis of article studies obtained in a general manner the necessary payment according to calculate kriminanty and diskriminanty hypersurface.  They show examples of how to define envelopes two families of spheres. These are family formulas transform coordinates defining the translational and helical movement. The results are illustrated by computer polygonal models.

Design unique buildings and structures is a complex task requiring high qualifications, training and experience specific performers. The article describes in detail the contents of the various etapovproektirovaniya, the basic requirements and features, starting with the technical specifications of the project and finishing expertise. Outlines the features of pre-training, the issues that must be resolved before the start of work. We consider the load that must be considered and especially the calculations. The requirements on the development of specific technical specifications (CTS) on the object and scientific and technical support of the project (NTS) Particular attention is given of experimental studies of physical models of buildings and unique structures. The following material can serve as a basis for program and algorithm for the design of long-span and high-rise buildings and unique structures.

  Is considered non-stationary axisymmetric problem for fine round bimorph plate under the action of the top end surface of the normal stresses, being an arbitrary function of radial coordi-nates and time. On the basis of the theory of Tymoshenko by the method of finite integral transformations built a a new solution for the electroelasticity system stepwise  variable thickness and stiffness. The obtained relations allow to investigate the stress-strain state and the potential difference between external electrodes bimorph elements.

  Laboratory technology was developed to fabricate flexible piezocomposites with ferroelectric phase - polymers having signal reception factorv • gv 5000 • 10-15 m2 / N. The values of the given coefficient were achieved by switching from a probabilistic (spontaneous) percolation to a correlated one in the process of forming material. This made the production of 0-1–3 piezocomposites, in which a part of piezophase has 0 connectivity, and the other part – 1 connectivity possible. To improve the efficiency of piezocomposite polarization before their manufacturing the surface of piezophase particles, which were obtained by the partial destruction of the porous frameworks, was treated with coupling agent, which did not only improve the polymer adhesion to piezophase, but also allowed the removal of water from the particle surface. The latter effect reduced the value of interfacial conductivity, i.e. prevented the voltage drop of the polarizing field. Matching of polymer conductivity and piezoceramic particles by determining the optimal polarization temperature was carried out as well.

At the end of 2012 – the middle of 2013 pilot questioning among RGSU students was carried out. In total more than 330 students of the first and second courses were interrogated. The work purpose – measurement of dynamics of an emotional component of group installations in relation to a political order. The emotional component of group political installation was measured on technology of semantic differential. It was offered to estimate to respondents on 20 bimodal scales four types political about. Two ideal – ideally positive and ideally negative orders. And two real – local and central. In the linear approximation calculated levels of emotional perception of the political order in the vicinity of the averaged image of the real image of the ideal order to constructs used in the space of features. Perception of an order at the end of 2012 in Region: -0,21892, in Russia: -0,24154 . To the middle of 2013 level of perception decreased: in Region: -0,59429, in Russia: -0,43879 . For the considered period level of a relative deprivation also was analysed: in 2012 level is equal 0,523 and in 2013 made 0,555. Thus, to the middle of 2013 there is a small increase in level of a deprivation that correlates with deterioration of perception of a political order among youth.
