Specific features of entrepreneurial departments management in Russian companies

The topic is considered to be relevant due to the fact that entrepreneurship is necessary for the businesses survival and development worldwide, including Russia, and today some Russian companies are adapting their economies to the more developed economic standards. The entrepreneurial format adoption is an important stage of development for possible changes and growth in the future. The aim of this research work is to analyze some approaches to the phenomenon of entrepreneurship, to determine some specific features of entrepreneurial departments, including in the context of the Russian business space, and to study specific characteristics of these departments management in Russian companies. The main methods used in the study are the theoretical materials analysis, as well as the analysis of statistical data in the study area, the method of expert judgments, the survey method. The research work included the study of Russian entrepreneurship experience, specific features of entrepreneurial departments. The specific features of the Russian entrepreneurship were identified during the own diagnostic research, as well as some entrepreneurial difficulties caused by the entrepreneurship. Identified due to this research peculiarities of Russian entrepreneurship and difficulties of this phenomenon development in the Russian business space will allow to develop the Russian entrepreneurial business model based on its specific characteristics. On the basis of the obtained data a special mechanism can be created for the support and development of intra-entrepreneurship departments within the overall entrepreneurship management mechanism in Russian companies, where the full range of necessary organizational and economic conditions, as well as the possibilities for entrepreneurial results assessment will be presented, combined with a complete list of tools to facilitate the emergence and development of intrarepreneurship in companies. © 2016 Troshina et al

Environmental risk to health of the population

Researches of the last years in the field of ecological epidemiology and the analysis of risk for health allow to claim with confidence that the polluted environment is one of the important factors defining changes of a state of health of the population. Expert opinions on the scale of this influence differ considerably now. These estimations vary from small shares of percent to several percent, reaching in some cases 30-50%. An attempt to elaborate economic approaches to a risk assessment to health of the population has been made in this work. The main reason which demands development of special approaches for an assessment of an environmental risk is that quantitative estimation of risk for health from environmental pollution is difficult to be realized. As a rule, population is affected by the whole set of the polluting substances from the atmosphere, drinking water, food, etc. For effective risk management it is necessary to assess and compare diverse risks caused by action of various pollutants coming to an organism in different ways. The stated methodical materials give an idea of possibility of the stage-by-stage multilevel risk analysis at the solution of environmental problems. Further comparative analysis connected with definition and comparison of various dangers can be done by means of the results received at a risk evaluation stage. © 2016 Anopchenko et al

Biosensing platform combining label-free and labelled analysis using Bloch surface waves

Bloch surface waves (BSW) propagating at the boundary of truncated photonic crystals (1D-PC) have emerged as an attractive approach for label-free sensing in plasmon-like sensor configurations. Due to the very low losses in such dielectric thin film stacks, BSW feature very low angular resonance widths compared to the surface plasmon resonance (SPR) case. Besides label-free operation, the large field enhancement and the absence of quenching allow utilizing BSW coupled fluorescence detection to additionally sense the presence of fluorescent labels. This approach can be adapted to the case of angularly resolved resonance detection, thus giving rise to a combined label-free / labelled biosensor platform. It features a parallel analysis of multiple spots arranged as a one-dimensional array inside a microfluidic channel of a disposable chip. Application of such a combined biosensing approach to the detection of the Angiopoietin-2 cancer biomarker in buffer solutions is reported

Label-free and fluorescence biosensing platform using one dimensional photonic crystal chips

The increasing demand for early detection of diseases drives the efforts to develop more and more sensitive techniques to detect biomarkers in extremely low concentrations. Electromagnetic modes at the surface of one dimensional photonic crystals, usually called Bloch surface waves, were demonstrated to enhance the resolution and constitute an attractive alternative to surface plasmon polariton optical biosensors. We report on the development of Bloch surface wave biochips operating in both label-free and fluorescence modes and demonstrate their use in ovalbumin recognition assays

Organizational Model of Regional Socio-Economic Territorial Management

The problem of accounting risk management of socio-economic development of territories has several aspects. Along with the relative novelty of the scientific development management, risk management tasks in industrial urbanization have not yet received sufficient methodological support. This article defined directions and tasks of captive insurance mechanism at the regional level, disclosed the peculiarities of captive insurance companies proposed mechanisms for its effective functioning. As a result, the study proposed a model of regional organization of risk management, the essence of which is to combine units monitoring organization and functional environment, to analyze the factors and assess the level of risk, as well as reference and methodological information. It is recommended to account for the industry-specific risk organizational structure of management and identify characteristics of the information flows three-component scheme of risks.

Electrical behavior of MIS devices based on Si nanoclusters embedded in SiOxNy and SiO2 films

We examined and compared the electrical properties of silica (SiO2) and silicon oxynitride (SiOxNy) layers embedding silicon nanoclusters (Sinc) integrated in metal-insulator-semiconductor (MIS) devices. The technique used for the deposition of such layers is the reactive magnetron sputtering of a pure SiO2 target under a mixture of hydrogen/argon plasma in which nitrogen is incorporated in the case of SiOxNy layer. Al/SiOxNy-Sinc/p-Si and Al/SiO2-Sinc/p-Si devices were fabricated and electrically characterized. Results showed a high rectification ratio (>104) for the SiOxNy-based device and a resistive behavior when nitrogen was not incorporating (SiO2-based device). For rectifier devices, the ideality factor depends on the SiOxNy layer thickness. The conduction mechanisms of both MIS diode structures were studied by analyzing thermal and bias dependences of the carriers transport in relation with the nitrogen content
