The article deals with development of hydropower in the Altai region. Indicates the need for widespread adoption in the economic practice of farms renewable energy. Provides information about the basic types of equipment of small hydro power plants. Analyzes the main problems encountered during the construction and operation of small hydroelectric power plants. In this time have a potential for the construction of small hydroelectric power stations for the needs of farms in the area of the foothill zone of the Altai Territory. It is noted that the implementation of such a project is possible only at the state level, because of the large amount of necessary investments. As a priority area of hydropower development for the needs of farms Altai proposed project of building 26 small hydro power plants on the rivers Charysh, Anouilh and Peschanaya. Indicated that the project could provide more than 95% of the needs of agriculture in the region's electricity . According to the analysis of the above issues,we can the following conclusions: (1) small hydropower plants are spent in terms of technology and affordable source of renewable energy, and (2) is now possible to create a sufficiently large hydroelectric complexes of low power, the ability to make a significant contribution to the region's energy supply structure and (3) the market has a large number of manufacturers of equipment for hydroelectric small power, including and domestic enterprises, which allows to put into practice projects by individual energy supply, without any technical difficulties, (4) the high priority in the development of small hydro power plants, in relation to the needs of the agriculture of the Altai Territory is to create a pool of 26 small hydro power plants on the rivers Charysh, Anouilh and Peschanaya with a total installed capacity of 404 MW, with an annual production volume of 1540 million kWh of electricity per year, and (5) small hydropower plants are a priority of energy supply based on renewable energy sources of agrarian industry in the foothills southeast of Altai Territory.

Vocal speech is a random process. Taking into account the fact that the main characteristics of a singing voice vary with time, in the article vocal speech is studied as an acoustic nonstationary random process. To describe this process we should calculate one of its informative parameters – the autocorrelation function. The findings show that there are some differences between the autocorrelation functions for professional and nonprofessional singers. This helps to make a quantitative assessment of a singer’s professionalism which, alongside with a vocal teacher’s subjective assessment, can present an objective view on a singer’s voice and provide a good basis for optimization of academic voice training. Moreover a teacher does not have to be technically educated because this quantitative assessment is presented in diagrams which are quite easy to assess visually. It is especially important to consider when we use the given voice assessing method in music schools, colleges and universities.

Keywords: Vocal speech, acoustic signal, nonstationary random process, autocorrelation function, the maximum autocorrelation interval, quantitative assessment

The current system of intergovernmental fiscal relations , the trends of its development in Russia , including the alignment process , aimed at smoothing the territorial differentiation of socio- economic development of regions. The main task of any state , regardless of the device is to smooth regional disparities through a reallocation of financial resources. In this case, the stability of intergovernmental fiscal relations between the federal center and the subjects of the federation is largely determined by well-functioning system of fiscal federalism. Currently, the budget process is characterized by serious contradictions that arise during the development phase as well as on the stages of implementation of management decisions. Global experience demonstrates the lack of an optimal model of intergovernmental relations . Vertical alignment is the process of achieving a balance between the commitment of each level of government expenditure with the potential of its revenue sources . The tools include the vertical alignment of the fixing of taxes for a certain level , subventions and subsidies, regulating the distribution of income. The horizontal alignment is aimed at providing a unified standard level of consumption of public services to the residents of different regions of the country. With reference to the Russian economic space horizontal alignment problems are quite complex , since there are strong differences in socio-economic development of the regions due to climatic and historical factors .

This article reviews systems of respiratory activity registration in relation to sports medicine. Attention is devoted to the use of miniature accelerometers that record the movement of the chest, as the optimal method for the diagnosis of the respiratory parameters. Other methods are based on piezo-resistive sensors, pressure and airflow sensors, and airways resistance sensors. The authors' developed device based on three-axis accelerometer is proposed. It recognizes episodes of apnea with sufficient accuracy for long-term monitoring. The algorithm of the accelerometer data processing is described. In order to minimize noise impact on the useful signal it is necessary to transform the three-dimensional cloud of accelerometer data into a flat sector. Then the relation of gravity vector deviation angle and the nominal position in time is determined. This presented device due to its ability to transmit data via Bluetooth technology, after appropriate software development for mobile phone and the receiving terminal of medical professional, will be able to organize a simple ergonomic long-term remote monitoring of respiratory activity.

The catalytic activity of Pt/C and PtxNi/C electrocatalysts prepared by  borohydride methode was studed. It was established that the specific activity  of fresh prepared Pt3,7Ni/C  catalyst  in oxygen  electroreduction  reaction is higher in compare with Pt/C material. After treatment of Pt3,7Ni/C material in the hot acid  nickel in the surface layers of nanoparticles was dissolved and the composition of nanoparticles was changed to Pt5,6Ni. The electrochemical surface area of the Pt5,6Ni catalyst and specific activity was slightly decreased after corrosion treatment.
