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. 

Keywords: sources, volumes, oil components, the Black Sea, hydrocarbons

The article opens the analysis of a role of factors of production in economic processes. The conclusion that a key influencing element of domination of a factor of production is ensuring competitive advantage with it in production is reasoned. Theoretical justification of influence of a key factor of production on processes of creation and cost distribution is given. Comparison of use of dominating factors of production and their contribution to economic development of the country is given in article. Comparison is given over economically developed countries and Russia. Also researches of innovative development of the countries are given in article, given the International research groups, and the main problems of formation and development of the Russian national innovative system are specified.

In article it is briefly considered stages of formation of definition of strategic marketing in scientific literature of Russia. The importance of a services sector in economy and the importance of modernization of the given sphere for the general development of economy as a whole locates. The analysis of dynamics of paid services to the population that will allow to reveal the sphere of servants with the greatest volume of consumption among the population is carried out. Are considered the sphere of transport services of the Rostov region, as a result of research SWOT analysis of marketing strategy is carried out to projections to the sphere of transport services of the Rostov region and recommendations to transport companies of the Rostov region for a choice of suitable marketing strategy are made.

Keywords: diversification of management, production diversification, financial and economic purposes of a diversification, technological purposes of ensuring flexibility of production

The article includes the theoretical aspects of real estate financing, lenders' and borrowers' risks in construction lending. There is information about the analysis of real estate financing in the Russian Federation according to the CBR and FSGS. The results demonstrated a "revival" in construction lending in Russia, reducing the arrears borrowers’ construction sector and identified the benefits of bank lending to construction companies

The proposed method of designing hardware components optical switching systems simplifies prototyping and development of systems of optical switching and multi-core VLSI. This method allows to automatically set parameters of the optical system at the design stage, depending on the requirements. This method may be cost-effective at the stage of technical specifications of the project, as will reduce the time required for its coordination between the customer and the design engineer.
At the heart of developing a method of designing systems, optical switching elements is a comprehensive analysis of the equations and functions describing the electrical and optical properties of laser heterostructures, as well as electro-optic modulators and Fabry-Perrot resonators. Fundamental static and dynamic characteristics of semiconductor diode lasers can be calculated by using a set of kinetic equations describing the interaction of electrons, holes and photons in the active layer of the laser structure. At various stages of this method is processing, evaluation and calculation of the main characteristics of the elements of integrated optical switching systems.  

Keywords: optical switching, integrated injection laser, quantum-scale heterostructure, amplitude modulation, terahertz range
