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 results of analysis of computational aspects of the method of obtaining the XANES spectra for Ru L2 ,3-edges by integrating the dipole transition matrix elements involving DFT. The convergence of the numerical integration procedure for the parameters used in the earlier papers, crystals as an example [Ru (NH3) 6] 3 +. More specifically, it is proved that it is possible to use a small area of ​​integration and big enough step between points, which helps to minimize the requirements for computing power and offers the prospect of using this method for the simulation of the XANES spectra in coordinated ruthenium catalysts for splitting water research in the field of solar energy.

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.

The analytical method determination parameters of the three-parametrical Waybill distribution for final volume population on the basis received parameters on a sample is stated in this work The algorithm of calculation on which computing experiment is made is presented. 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.
