The possibility of increasing the reliability of assessing air pollution through the use of probabilistic methods is shown. Evaluation of quality indicators on a quantitative basis made it possible to find an error of the first and second kind in assessing the quality of the atmosphere. Based on the Bayesian approach, dependencies were obtained for estimating and predicting atmospheric pollution in the area of ​​a city that does not have a stationary post, based on data from stationary posts in other areas.

Keywords: atmosphere quality, reliability of the estimate, probabilistic methods, quantitative characteristic, error of the first and second kind, Bayesian approach, a priori probability, posterior probability, likelihood of a quantity

First-principles simulation of ultrathin amorphous carbon films has been performed. Nanohybrid graphene-C60 systems were considered. Total energy calculations were performed using pseudopotential method within density functional theory. Local atomic structure and electronic energy spectrum of the systems were studied. It was demonstrated that fullerene-graphene interaction results in significant deformation of their local atomic structure. Obtained results are in good agreement with experimental X-ray UV spectra of hydrogenated amorphous carbon

Keywords: Phase-change resistive memory, ab-initio simulation, pseudopotential method, Kohn-Sham method, graphene, fullerenes, amorphous carbon, atomic structure, electronic structure, adsorption energy

  Structural changes in cumulative labor displace the purposes of social development and generate understanding of that the economy exists for the person, and people – the main value of modern society. The evolution of the term tracked in article the sociolabor relations, consideration of elements, levels and the purposes of the sociolabor relations, the characteristic of types of regulation of the sociolabor relations and an assessment of system of the sociolabor relations of Russia allowed to add definitions of the sociolabor relations by concept «the human capital» and to define system of the sociolabor relations of market economy as a complex of relationship concerning development and effective use of the human capital. 

Keywords: Sociolabor relations, hired worker, employer, work, human capital
