Mathematic model considers the geometrical and physical nonlinearity, the adaptability of creep flow. Arc work is accounted for by the method of constructive anisotropy, but with due regard for shear and torsion rigidity. In solving physically nonlinear problems, secant modulus is defined directly from the «σ-ε» curve, found experimentally. Mathematic model is written in the form of functional of total deformation energy. This model can be used for comprehensive analysis of the stability of reinforced shells of revolution.

Keywords: stability of reinforced shells of revolution, linear-elastic problems, the nonlinear-elastic problems, the problem of creep flow.

The sensor design on surface acoustic waves (SAW), representing the delay line with unidirectional inter-digital transducers (IDT) is considered. The factor of reflection of SAW from the unidirectional IDT loaded on impedance depending on value of resistance connected to it is investigated. On dependence of factor of reflection on size of resistance there is almost linear site at values of resistance more than 50 Ohm. The new design of the connected lattices of nanowire of zinc oxide, having the general resistance in a range of 50-250 Ohm which is connected to reflective IDT as loading is developed.

Theoretical analysis of constructive and technological restrictions in the avalanche photodiode structure for photon-counting mode is made in this work. It is shown that critical parameters are load resistance and a time constant of a photodiode internal capacity recharge. For decreasing this time constant one needs size restriction of separate section of the photodiode and association of several such sections on a crystal together with registration schemes.

A modified analog-SSOR of variation type is used for numerical realization of two-dimensional discrete mathematical model of the aquatic environment, which is based on a three-dimensional hydrostatic model. Governing equations of the given model are equations for incompressible fluid, hydrostatic equation and Navier-Stokes equation. Developed model is used to predict the processes of sedimentation and the impact of negative factors affecting the condition of coastal and offshore structures. An algorithm for the minimal residuals modified analog-SSOR method for solving the difference equations is presented in the paper. The results of numerical experiments are presented.

It was investigated the influence several additives and process parameters on the properties of piezoelectric ceramics based on PZT phase systems. It was shown that the use of the substitution of Pb2+ ions on the Bi3+, and Ti4+ ions, and Zr4+ to Fe3+ and Mn4+, as well as the method of "chemical assembly «allows to obtain increase the Curie temperature of ceramic samples of 50 - 170°C. The theoretical aspects of this area of research have been discussed in this article.

The paper presents the results of research level of perception a political order among students of Grozny (GGNI) at the beginning of 2012. The questioning method was used. In total 320 respondents were interviewed, and captured the age group from 17 years to 20 years. On national structure the group was almost uniform (95,9% - Chechens). The main purpose of questioning - the definition of the emotional component of the group political installation on the classical method of semantic differential Charles Osgood. A comparative analysis was carried out of the averaged semantic level of emotional portraits and making real political order. It is revealed, the image of an order is in the Republic 45% closer to positive "ideal" construct in comparison with image of an order in Russia as a whole. It is received, by the beginning of 2012 perception level considerably decreased to normal value (in comparison with "incredibly positive" 2011). Thus small excess of perception of a political order in the Republic remained.

On the basis of these calculations the conclusion that it is necessary to determine by this analytical method parameters of the three-parametrical law of Waybill for set of final volume on the basis of the received parameters on a sample is drawn.

  Results of the flight research spent in student's RBSU environment in December, 2011 are presented. The method of semantic differential is put in a basis of questioning. Respondents were offered to estimate four types of a political order by using of 20 double modal seven-ball scales. Two "ideal" orders are as much as possible attractive order and as much as possible unattractive one. And two real orders are the political order existing in Rostov region and a political order in Russia as a whole. The estimation was spent in linear approach, and also in frameworks the early developed phenomenological model considering typical nonlinearity, which is probable for a considered case. It is received, that in the end of 2011 students were characterized by negative perception as political order in area (with level -0.7, a level was normalized from +1 to-1), so an order in Russia in whole (with level -0.77). Surfaces of the stationary states, allowing to detail dynamics of change of perception level are calculated. Comparative dynamics of behaviour of emotional perception level of real political orders from the end 2009 on the end 2011 is presented.
