Data on environmental monitoring and the marine environment pollution by oil are presented and new highly efficient technical means of oil-containing water purification systems are developed, which have high quality of oil-containing water purification, a long service life of filter elements, simple design and operation. The combined separation system for the purification of oily waters has a high efficiency and provides the purification of oily waters to a concentration of petroleum products lower than 5 million-1. The design of the regenerated filter and separator with granular loading ensures the regeneration of filter elements without disassembling and replacing them, which significantly simplifies the maintenance and operation of the system.

The shared economy has been developing rapidly with low cost, low consumption and high environmental efficiency features under the background of internet waves. The shared economy model has emerged in housing, catering, and travel. As people look forward to high quality of life and their social interaction need, the shared kitchen platform arises at the right moment. This paper takes the shared kitchen as an example, focusing on the patients and their caregivers, the existing shared kitchens and its service platform as well as the space system design and human-computer interaction of the shared kitchen have been investigated and analysized. Taking the "high efficiency, the intelligence and the humanization" as the design principles, we are committed to exploring new directions for modular kitchen design under the background of shared economy.

The theory of the executive activity of a personality and the ability to determine its correlates are analyzed. High efficiency executive activity is considered as a predictor of a high quality of life and professional activity of an individual. The results of the study of the individual psychological properties of the personality associated with the characteristics of performing activities are presented. A combination of properties is highlighted: irritability, sociability, extraversion, which positively affect the type of execution. They form a triad closely associated with all the properties of executive activities. Some personality properties that inhibit the development of characteristics necessary for effectiveness are identified. Aggressiveness and high emotional lability are characteristic of students with low responsibility. According to the research results, mutually exclusive properties are organization and openness. The definition of determinants and correlates of performing activities opens up opportunities for psychologists and educators to create spaces for the development of a highly effective personality. Executive activity is a system construct. Understanding its structure allows us to see its flexibility and form individual trajectories of learning and personality development.

The paper describes the widespread types of filtering materials and their specifications. It is shown that a filtering material is characterized by a number of parameters influencing both operating parameters of filtering systems and the efficiency of conditioned natural water purification. Changing these parameters, it is possible to predetermine the operating parameters of filtering systems and the quality of purified water. At a design stage of filtering systems it is necessary to determine the effective parameters of the filtering material, such as the height of the working layer, fineness and heterogeneity of fractions, and filtration rate to achieve the high quality purified water. It is shown that the finer fraction of the filtering material allows to increase the filtration rate preserving the quality of obtained water and, respectively, the productivity of filtering systems due to the increased specific surface of grains despite the increase in the load resistance and pressure losses.

ABSTRACTA total area conversion efficiency of 10.2% has been achieved for a 1Ocm×1Ocm integrated-type single-junction amorphous silicon (a-Si) solar cell submodule. It is the highest conversion efficiency ever reported for an a-Si solar cell with an area of 100cm2, including multi-junction cells. The effective area conversion efficiency is as high as 11.3%. The high efficiency is obtained by improving the quality of the i-layer and the p/i buffer layer, as well as by utilizing a highly textured, high-quality transparent electrode. The quality of the i-layer plays a dominant role in the performance of a-Si solar cells, especially in high efficiency cells. Techniques that control the properties of the high-quality a-Si films for the i-layer are described. Electric conductivity, ESR spin density and the Raman spectra of high-quality a-Si:H films are investigated as well as their thickness-dependence and substrate-dependence.A Through-Hole Contact (THC) integrated-type submodule has been developed as a new-type a-Si solar cell module structure. Numerical simulations on the output power of the structure show that the output power can be significantly improved by the THC structure.

AbstractCurrently in Russia and other countries in family farms there is a demand for lowering cost of animal production. Main direction to achieve new terchnological solutions characterized by low energy constumption and high efficiency with maintaining high quality of product (mineral). For example, lately in animal production are acquired concentrates with low unity costs. Realising targets releated with lowering costs of forage production with usage comminution and crease of grain. Previously conducted own researches and literature analises shows, that currently used solutions are characterized by big errors made by construction of the devices, and technology effect of obtained product (grain). The paper presents the criteria for optimalization of technical indicators of shredding devices affecting the quality of the product.
