The article describes methods allows to control the degree of anisotropy piezoelectric ceramics based on doped phase PbTiO3. As a model of the object has been selected phase of Pb0,76Ca0,24Ti0,94(Cd0,5W0,5)0,06O3. The model phase was obtained by the following methods: by solid state reaction method and the chemical construction. For comparison phases obtained by these methods were used modern analytical research methods (DTA, TGA, XRF, XRD, power and tunneling microscopy, computer-program research results). Piezoceramic samples were obtained from the synthesized phases and electrical parameters were measured. Were revealed that the samples, obtained from the charge, synthesized by chemical construction had values of  piezoelectric constants d31 and d33 much more than samples obtained by the method of solid state reaction.

The expediency of in-home population health services development is shown, forms of such service are specified. Advantages of medical equipment for in-home application (MEfIHA) usage from positions of patients are proved. Results of the population questioning, concerning with MEfIHA usage, executed by authors are presented. Structure MEfIHA available in sale and actually used by population is compared. For the majority of MEfIHA kinds their functionality, ranges of costs, features of application by patients are characterized. Variants of maintenance service for MEfIHA are investigated. The conclusion, that volumes of population MEfIHA usage are insufficient, are substantiated.

It is shown that to describe the phenomena and processes in a transition interfacial layer having a certain thickness, it is useful to distinguish the boundary layer of the surface and boundary diffusion layer, which lies entirely in the less condensed phase related. In accordance with this energy and power characteristics of the transition layer should be attributed to the boundary surface of the interphase transition layer. The basic equation of electro capillary boundary of the surface layer, establishing the dependence of the surface tension of this layer on the chemical composition of the second phase, and bordering the jump of electric potential between them.

The article “Modeling adaptation strategies of social intellect of the Russian students” applies adapting and decoding models of defining, forming and measuring social intellect in peer groups of testees: pupils, students and teachers. Considering essential views on the nature of social intellect makes it possible to formulate the system of its characteristics of essence which is revealed as generic characteristics of social intellect. This approach might serve as a methodological prerequisite for further examining the essence of social intellect, its properties and functions.

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.
