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.
Keywords: Interphase layer, Entropy, Concentration, Adsorption, Surface tension boundary layer, the surface energy, electrochemical electrode

We describe the hardware and software package designed to get the dependencies of instantaneous values of the electric field E of the magnetic field H, and, depending on the module surface impedance and phase shift of the electric and magnetic fields on the amplitude of the alternating magnetic field. The digital synchronous detection method applied in this article to analyze the spectral response of the substances. This article gives the results for ferromagnetic materials, paramagnetic materials and dielectrics.
Keywords: surface impedance, ferromagnetisms, alternating magnetic field, alternating electric field, digital synchronous detection.

In article the concept and structure of the human capital, the investment as a basis of its formation are considered; classification and features of investments into the human capital; an optimum parity of market and state investments into the human capital. Creation of the scientifically-educational centers promoting integration of the advanced researches and formation, for the purpose of growth of the human capital in Russia and to its more effective use is offered.
Keywords: reproduction of the human capital, the investment into the human capital, features of investments into the human capital, components of the human capital, the scientifically-educational center.
The basis for building the effective system of making a decision on municipal level is necessary to develop an activities of sustainable development. The system of municipal indicators of a sustainable development allows to estimate stability development of a territory, results of implementation of existing regional target programs, timely reveal the becoming problems, to correct plans of social and economic development of the region.
Keywords: sustainable development, municipality, indicator, efficiency, system
The article examines features of the backlog of business formation for design companies of road-building complex which apply value-based management system. The most important factors influencing the decision making about inclusion potential projects in the backlog of business are considered. The close attention is payed to substantiation of VBM metrics reflecting the contribution of projects to value creation by analyzed companies, and to value modeling of projects which let to evaluate projects depending on tender prices.
Keywords: Backlog of business, value-based management, Design Company, tender.
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.
Keywords: passive sensors, ZnO nanowire, surface acoustic waves, interdigital transducer.
Analog-to-digital converter, with modulation, amplification and demodulation of the input signal is carried out. To compensate the additional error of voltage conversion, concerned with temperature instability, used dynamic cancellation technique, based on the correlation between offset voltage and modulator temperature fluctuation. ADC with response time 0.85 s performs the threshold of sensitivity 1 nV; 8,5 s - 0,31 nV, 85 s - 0.13 nV, 850 s - 0.1 nV, respectively, in the full-scale range 400 mV. Estimation of offset voltage temperature drift is 40 pV / ºC, time drift - 100 pV / h.
