Abstract: We extend the exploration regarding dynamic approach of macroeconomic variables by tackling systematically expenditure using Statistical Physics models (for the first time to the best of our knowledge). Also, using polynomial distribution which characterizes the behavior of dynamic systems in certain situations, we extend also our analysis to mean income data from the UK that span for a time interval of 35 years. We find that most of the values for coefficient of determination obtained from fitting the data from consecutive years analysis to be above 80%. We used for our analysis first degree polynomial, but higher degree polynomials and longer time intervals between the years considered can dramatically increase goodness of the fit. As this methodology was applied successfully to income and wealth, we can conclude that macroeconomic systems can be treated similarly to dynamic systems from Physics. Subsequently, the analysis could be extended to other macroeconomic indicators.

Abstract: A New analysis of the electrical resistivity has been studied for Cu-Mn Kondo alloys, and it was found a solution like a logarithm power series between resistivity and temperature, which cover all ranges of maximum and minimum in the resistivity and all kinds of interactions at low temperatures. The s-d exchange integral Jsd acting the main role in Kondo effect Phenomenon, Jsd is negative or positive, according to a kind of interaction between conduction electron spins of the host normal metal and localized spins of the transition element. PACS: 75: 50, 75:10, 75: 40, 75: 30.

Abstract: As a result of work are received p-n heterojunctions in thin-film execution, described by high values of differential resistance. Results of researches show, that film p-n the structures received by a method of discrete thermal evaporation in a uniform work cycle, are suitable for use in low-voltage devices. The effect of conditions of precipitation on clarifying properties SiOх of surface slicks for thermophotovoltaic elements on a basis Bi2Se3 and Bi2Te3 is probed. The comparison with values of a current density of short-circuit raw of thermophotovoltaic elements is conducted. The augmentation of a current density with body height of concentration of oxygen in a mixed gas is exhibited during precipitation of a film that is explained by smaller absorption of a light in a film. For the maximal augmentation of a current of short-circuit of thermophotovoltaic elements the optimum thickness of optical stratums is defined.
