In this paper, based on Darcy equations that govern the lubricant in porous layers , and the modified Reynolds equation in the framework of a short bearing solve the problem of unsteady motion of a viscous incompressible lubricant in the bearing clearance double-layer porous . Here we consider the case when the permeability in porous layers in the axial direction is changed by the normal law , and the combined feed lubrication is performed simultaneously in the axial and perpendicular to the bearing axis directions. As a result, the pressure field found in porous layers and in the lubricating layer and analytical dependences for the efforts of the oil film . Compiled by the equation of motion tongue and solved the problem of the stability of the unsteady motion of a pin bearing , found that in the case of a combined bearing lubrication working more steadily compared with the cases or axial directions perpendicular to the axis lubrication . The results obtained can be offered for the development of cylindrical dampers with double-layer porous collar , effectively attenuating transmitted force imbalance in the combined feed lubrication.

The article examines the cognitive and behavioral components of group attitudes toward political order of students of DGTU.  Pilot study took place in 2013 and was carried out using questionnaires, which was attended by 52 people. The analysis represents a hierarchical clustering on the basis of consecutive factorization. It is received, group level of a relative deprivation – 0,46. In assessing deprivation group decomposed into two subgroups, with average values in each - 0.3 and 0.6. Perceptions of political order at the cognitive level:  -0,174 for local government and-0,139 for Russia. In perception of local government the group broke into two subgroups: -0,3 and 0,2. Behavioral component perception of political order defined by two subfactor: active behavioral level - 0.39, and the estimated level of oppositional behavior - 0.57.

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.

Fe-doped AlN nanorods were studied by means of x-ray absorption spectroscopy above the Fe K- and L2,3- edges. Theoretical simulations of the x-ray absorption spectra show that Fe atoms mainly substitute Al. A minor fraction of Fe interstitials or Fe-Al-N ternary alloy can be identified as well. Bader’s AIM analysis predicts that neutral substitutional FeAl defect is in 2+ charge state, though Al in pure AlN is in 3+ charge state.  Fe L2,3 absorption spectra and photoluminescence data indicate the coexistence of Fe2+/Fe3+ in AlN:Fe nanorods so different charge states of substitutional FeAl should co-exist.

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.
