    The vision status in teleut native countymen residing in Kemerovo Region. Studied structure and prevalence of eye disease have been evaluated following ophthalmologic examination of 609 teleuts (213 men and 396 women) accounting for 30% of the whole population residing at this area. The general population disease rate was found to account for 1 394,08‰.Изучено состояние органа зрения у коренного малочисленного населения - телеутов, проживающих на территории Кемеровской области. Установлены структура, распространенность и особенности формирования болезней глаз на основании осмотра 609 телеутов (213 мужчин и 396 женщин), составивших высокорепрезентативную выборочную совокупность (более 30% общего количества проживающих на данной территории коренных сельских жителей). Общепопуляционный показатель распространенности болезней глаз составил 1 394,08‰

    Coal is one of the main energy resources and development of new promising technologies on its basis is certainly topical. This article discusses the use of new technology of gas and fuel oil replacement by mechanically activated micronized coal in power engineering: ignition and stabilization of pulverized coal flame combustion, as well as gasification of micronized coal in the flow. The new technology coal combustion with two stages of grinding is suggested. Optimization of the scheme of two-stage combustion is calculated. The first experimental data on the combustion process are obtained. The first demonstration tests on gas and heavy oil replacement by micronized coal during boiler ignition were carried out in the real power boiler with the capacity of 320 tons of steam per hour

    MODELING OF PROCESSES OF CONTACT MELTING WITH THE SURFACE QUASI-LIQUID LAYER

    A contact melting model based on the possible existence of a quasiliquid layer on the metal surface is proposed. Using the interaction potentials between metal atoms, the temperature at which a quasiliquid layer will exist on the surface of at least one of them upon contact of their surfaces is calculated. It is shown that this temperature is lower than that realized in experiments on contact melting

    В статье представлено обоснование необходимости внедрения электронно-коммуникационной площадки в социально-экономическом аспекте для сферы образования. Предложены основы архитектуры, базирующиеся на задачах участников, которые они могут решить при использовании, а также влияние функционирования такой площадки на качество образования и развития науки в стране.The article presents a rationale for the need to introduce an electronic communication platform in the socio-economic aspect for the education sector. The fundamentals of architecture are proposed, based on the tasks of the participants that they can solve when used, as well as the impact of the functioning of such a platform on the quality of education and the development of science in the country

    Impact Factor: outdated artefact or stepping-stone to journal certification?

    A review of Garfield's journal impact factor and its specific implementation as the Thomson Reuters Impact Factor reveals several weaknesses in this commonly-used indicator of journal standing. Key limitations include the mismatch between citing and cited documents, the deceptive display of three decimals that belies the real precision, and the absence of confidence intervals. These are minor issues that are easily amended and should be corrected, but more substantive improvements are needed. There are indications that the scientific community seeks and needs better certification of journal procedures to improve the quality of published science. Comprehensive certification of editorial and review procedures could help ensure adequate procedures to detect duplicate and fraudulent submissions.Comment: 25 pages, 12 figures, 6 table

    A research aiming at assessing the effectiveness of LAP technology has been conducted. It has been found that this technology allows one to process product surfaces with a roughness less than Ra 0.5 μm with a slight increase in asperity. As a result, a clean matte surface is achieved. © 2016 Author(s)
