Opis:
This paper presents the first results on formation and study of structure and properties of micro- and nanocomposite combined coatings. By means of modeling the deposition processes (deposition conditions, current density-discharge, plasma composition and density, voltage) we formed the three-layer nanocomposite coatings of Ti-Al-N/Ti-N/$Al_2O_3$. The coating composition, structure and properties were studied using physical and nuclear-physical methods. The Rutherford proton and helium ion backscattering, scanning electron microscopy with microanalysis, grazing incidence X-ray diffraction, as well as nanohardness tests (hardness) were used. Measurements of wear resistance and corrosion resistance in NaCl, HCl and $H_2SO_4$ solutions were also performed. For testing mechanical properties such characteristics of layered structures as hardness H, elastic modulus E: $H^3//E^2$ etc. were measured. It is demonstrated that the formed three-layer nanocomposite coatings have hardness of 32 to 36 GPa and elastic modulus of 328 ± 18 to 364 ± 14 GPa. Its wear resistance (cylinder-surface friction) increased by factor of 17 to 25 in comparison with the substrate (stainless steel). The layers thickness was in the range of 56-120 μm.

Opis:
Using the two technologies: plasma-detonation and vacuum-arc deposition, we fabricated two types of coatings: Ti-Si-N/WC-Co-Cr/steel and Ti-Si-N/steel. We found that the top coating of Ti-Si-N was nanostructured one with 12 to 15 nm grain sizes and H = 40 to 38 GPa hardness. A thick coating which was deposited using the pulsed plasma jet, demonstrated 11 to 15.3 GPa hardness, an elastic modulus (E) changing within 176 to 240 GPa, and tungsten carbide grain dimensions varying from 150 to 350 nm to several microns. An X-ray diffraction analysis shows that the coating has the following phase composition: TiN, (Ti,Si)N solid solution, WC, $W_2C$ tungsten carbides. An element analysis was performed using energy dispersive spectroscopy (microanalysis) and scanning electron microscopy, as well as the Rutherford backscattering of $\text{}^4He^{+}$ ion and the Auger electron spectroscopy. Surface morphology and structure were analyzed using scanning electron microscopy and scanning tunnel microscopy. Tests friction and resistance (cylinder-plane) demonstrated essential resistance to abrasive wear and corrosion in the solution. The decrease of grain dimensions ≤ 10 nm occurring in the top Ti-Si-N coating layer increased the sample hardness to 42 ± 2.7 GPa under $Ti_{72}-Si_8-N_{20}$ at.% concentration.

Opis:
The characteristics of territorial distribution of greenhouse gas emission sources have been analyzed for eastern Polish regions. Mathematical models and information technology for spatial analysis of greenhouse gas emissions from fossil fuel consumption of heat/power plants and households have been developed in consideration of the territorial distribution of greenhouse gas emission sources and structure of statistical data for the Polish voivodships: lubelskie, podkarpackie, podlaskie, and świętokrzyskie. The results of spatial analysis for these eastern voivodeships are presented in the form of thematic maps. Key words: information technology, spatial analysis, greenhouse gas emissions, heat/power plant, residential sector, fossil fuel.

Opis:
The current state of the labor market in Ukraine is researched. A lot of processes are irregular and uncontrollable as a result of shadow or informal employment at the market nowadays. Different structural and cyclical influences caused high unemployment and a gap between labor market needs and labor force qualification and education. The impact of the political crisis on employment has been related to a large and growing internal flow of people leaving the areas of warfare and looking for new jobs. The migration of the working age population to other countries has accelerated over the last years. Thus it is important to increase the economic activity of young people by reduction of imbalance between supply and demand for labor, reduction of shadow employment, labor migration of young people. The problems and difficulties for university graduates in the job search and difficulties for employers related to hiring educated young people in the conditions of considerable supply of labor in the Ukrainian labor market are analyzed. The gaps of labor demand and supply are considered from two directions: graduates’ view – challenge of finding jobs for young people; employer’s view – complexity of the employee selection with a high employment potential and an adequate psychological portrait. The measures for preventing and solving the mentioned problems are proposed, among them innovative ways of interviewing and an algorithm for employers for finding highly skilled workers. It is stressed that the problems of employment in Ukraine can not be addressed in isolation from the global processes on the world labor market. The Association between Ukraine and the EU may have a significantl influence, increasing the number of migrant workers and mobility.

Opis:
This paper describes the development of geoinformation technology for the spatial analysis of greenhouse gas emissions caused by fossil fuel combustion in the industry sector in Poland. Mathematical models and software have been elaborated, which make it possible to calculate the emissions and construct an appropriate geospatial database. The models are based on algorithms of proxy data disaggregation to the level of point- and area-type emission sources. These tools take into account the non-uniformity of anthropogenic activity and spatial distribution of emission sources. Numerical experiments were conducted and the results of spatial analysis are presented in the form of digital maps.
