The substantiation of the need for the preparation of thermal hydraulic drive road construction machinery (SDM) operating in the North. Given that a significant number of failures falls on hydraulic drive elements, it becomes urgent need to study their work and causes of failures. In order to analyze the thermal training funds, the development of new systems is necessary to study thermal characteristics of hydraulic drive elements SDM operated at low subzero temperatures. It is necessary to take into account the rate of change of the processes occurring in the hydraulic drive. In accordance with the above requires a quality measuring equipment, created on the basis of analog-to-digital converters. For this analysis instrumentation for experimental studies. Currently, at the Department of Transportation and technological systems developed hardware and software for temperature measurement system for monitoring hydraulic drive elements SDM.

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.

The ability to choose the right anti-wear additives [1-6 ] allows you to create lubricants , which are thin layers have different properties than in large volumes. It is commonly assumed that the additives are functioning only in the zone boundary lubrication and are outside the scope of the hydrodynamic theory of lubrication . However, the beneficial effect of additives as indicated in many studies [1-5 ] we have in the " thin layer" of hydrodynamic lubrication .As is well known , lubrication bearings operate on different types of lubricants which are composed of base oil and additive compositions that provide the required functional properties of the oil . Additives polymers with high molecular weight oils impart viscoelastic properties . Analysis of existing studies [ 7-9] on the calculation of bearings running on a viscoelastic lubricant , shows that they do not take into account the dependence of the viscosity and shear modulus of the pressure and temperature, and mode of friction is assumed laminar. It is known [ 10 ] , high-speed bearings operating in turbulent friction , higher pressure and higher temperature, and so the development of methods for calculating the bearings running on a viscoelastic lubricant requires consideration of the above factors.In connection with the above written shall first develop the computational model of thrust bearings running on micropolar lubricant with the viscosity characteristics of the lubricant on the pressure in contrast to the existing theoretical models do not take into account these dependencies (task 1).And then consider the calculation model of extra load -bearing capacity , working on a viscoelastic lubricant for the dependence of its characteristics on the pressure (objective 2).
