In the article are introduced research results of physicochemical properties of ammonium nitrate – potassium nitrate water system at 25o C. The literary source analysis is performed that no clear opinion about solid phases composition. The different composition double salts, solid solution and eutectics are identifies. Appeal is specifies a look and properties of formed structures. Methods of differential thermal analysis and X-ray diffraction have been establishing that the equilibrium solid phase of the studied system represents two types of solid solutions. A first type based on the III phase of ammonium nitrate crystal latitude (at the content of nitrate of potassium to 20 %) and a second type based on the potassium nitrate rhombic syngony (at the content of nitrate of potassium more than 80 %). Crystal cells parameters of being formed phases submit to the Vegard rule. The ammonium nitrate sample (at the content of nitrate of potassium more than 12 %) keeps phase stability at the temperature range minus 50 to plus 100о С. Burst in components miscibility at the potassium nitrate concentration range 30 to 80 % is observed.

This paper presents a method of processing and interpreting data from the semantic differential technique. It is shown, the emotional perception calculated on the standard method of average values gives an incomplete picture. The technique is approved in research of emotional perception of the political order among DGTU students. It is obtained, distribution of the studied group is inhomogeneously on emotional perception of political orders. For audience as average, and the most probable levels of perception of local and central political orders are positive and equal 0,1. However, 27% of students are characterized by a negative level of emotional perception of political order, with the average value -0.3.

Currently, more than 80% of water conveyance structures worked much the normative life. At the same time there is a simultaneous increase in the load on the aging waterworks, in the absence of the necessary skilled personnel and technical repair base will inevitably lead to an increase in the number of accidents due to operational reasons. Identification of factors that influence the condition of the facilities at the intersections , the search for methods of calculation and control of non-destructive methods to evaluate their work , life extension , etc. is of paramount importance at this stage. Residual life for the safe operation of water conveyance structures determined on the basis of system analysis with the development of the block diagram of a dynamic system having a number of subsystems. The main property that determines the life of the system , is the reliability of its elements , ie reliability and trouble-free operation for a certain period of operation. Dependability and reliability of the system as a whole is determined by the condition that each element of the system can be in one of two states - serviceable or failure.

Specialized robots are occupying a vast share of researches worldwide. In terms of aerial specialized robots, autonomy is the one of the major subjects that are being studied. As  known, flight autonomy is consisting of three parts: Mission planning, trajectory generation and path tracking. While it exists variety of local and global generation algorithm, UAV path planning is always associated with machine vision. This intellectual approach is solid because it can give a dual supervision link to the situation being surveyed. The operator has always the authority to step in and stop any unwanted action. The machine vision based algorithm has a huge disadvantage due to homogeneity and identity factors. This is because from distance object tend to look the same geometrically as well as color wise. In this paper we offer a solution to tackle the homogeneity problem between tracked agents which can cause local minimum problems. The UAV will forecast the next position of the tracked agent using Artificial Neural Networks. Position estimation is based on registered previous coefficient.

The combination of the unique, abnormal properties shown by oxidic systems with structure of spinel on the basis of transitional elements chromites draws attention of researchers for many years. Some systems on the basis of transitional elements chromites (for example, nickel and copper chromites) have critical elements (multicritical points, lines of phase transitions of the second sort, etc.) on the phase chart. Near these elements of the phase chart materials possess unique chemical and physical properties. Therefore development methods of receiving and research of phase forming and properties in NIO-CoO-CuO-Cr2O3 system represent fundamental and practical interest for chemistry and technology of inorganic substances. In this work processes of spinel structure formation in system 0,6 NiCr2O4 – 0,2 CoCr2O4 – 0,2 CuCr2O4 from crystal chemistry positions are considered. Formation of two solid solutions on the basis of nickel (II) chromite – with structure of cubic spinel and with tetragonal distorted structure is established. The influence of cooperative Yahn-Teller effect on processes of a spinel forming and on stabilizing impact of chloride of potassium on process of education of  two spinel solid solutions is suggested. Influence of a power factor of cation stabilization in knots of a crystal lattice as one of the important factor in reaction of spinel structure formation is considered.

The paper is devoted with the analysis of sources and volumes of oil components’ input into the Black sea. The topicality of this problem is connected with of transboundary the status of water object that contributes to the complexity of such works. Black Sea has important significance for transport and development in the coastal zone of the oil complex, combined with a great recreational potential. As a result, ecosystems are technogenic impact. The paper describes the main natural and anthropogenic sources of oil components in the Black Sea. On the basis of the results of our expeditionary research and analysis of sources of pollutant concluded chronic character oil pollution of the Black Sea. And the conclusion that the most optimistic estimates, entrance of oil components in the ecosystem in the Black Sea is approximately 270 thousand tons per year, which is higher than the currently accepted values of 2−2.5 times.

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.
