Destruction mechanisms and methods of laboratory autoclave tests of internal coatings of oil pipes

The main mechanisms of destruction of internal anticorrosive polymer coatings (IACPC) of the inner surface of tubing and fielding pipes are review in the article. They are divide into decompression peeling, substrate destruction under the corrosion of and natural aging of the polymeric basis. A critical analysis of the existing standards for the testing of internal anticorrosive coatings was made. The carrying out test on these documents does not allow obtaining the destructions identical to those found during the exploitation of pipelines. Investigations on the selection of optimal regimes of autoclave tests and the methodology for conduct research are describe. A comparison for the results of laboratory and experimental field tests of the coatings presented. Document type: Articl

Компенсаторная перестройка бронхиальных сосудов в условиях нарушенного легочного кровотока

Внутритканевой инъекцией лимфатических сосудов желудка установлены некототорые особенности его регионального лимфообращения. Наличие обильных анастомозов между лимфатическими путями обусловливает отсутствие каких-либо ограниченных по току лимфы территорий желудка. Не наблюдается строгой закономерности направлений лимфатических сосудов из определенных отделов желудка в определенные группы лимфатических узлов. Лимфатические сети в толще желудочной стенки тесно взаимосвязаны и их отводящие сосуды ориентированы из глубоких слоев (слизистой оболочки) к поверхностным (серозной оболочке)

Assessment of the functional state of the autonomic nervous system of women doing the health improving physical training

Article is devoted to the problem of the analysis of visual and motor reactions of the women who are going in for health improving physical culture depending on polymorphisms of a gene of 5HTT of system in aspect of the predictive assessment of stability of reactions of central nervous system within dynamics of training loadings. It has been supposed that carriers of the various polymorphisms of genes of 5HTT have different resistance of central nervous system to development of the central exhaustion that is shown in dispersion of visual and motor reactions at physical activities. Research problem: to carry out the analysis of associations of polymorphic loci of genes of 5HTT of system with changes of indicators of a condition of TsNS and control before and after the physical and mental activities. The results of researches on studying of the psychophysiological condition of the women, confirming a hypothesis have been presented.Статья посвящена проблеме анализа зрительно-моторных реакций женщин, занимающихся оздоровительной физической культурой в зависимости от полиморфизмов гена 5НТТ системы в аспекте прогностической оценки устойчивости реакций ЦНС в динамике тренировочных нагрузок. Предполагалось, что носители различных полиморфизмов генов 5НТТ имеют разную устойчивость ЦНС к развитию центрального утомления, что проявляется в дисперсии зрительно-моторных реакций при физических нагрузках. Задача исследования: провести анализ ассоциаций полиморфных локусов генов 5НТТ системы с изменениями показателей состояния ЦНС и контроля до и после физических и психических нагрузок. Представлены результаты исследований по изучению психофизиологического состояния женщин, подтверждающие гипотезу

APPLICATION OF COGENERATION IN REPUBLIC OF MOLDOVA

Efficiency of gas engine cogeneration is investigated for the regional conditions of Moldova. The influence of different factors on the payback period is analyzed and discussed in detail. It is shown, that gas engine cogeneration is very profitable for Moldova and can be recommended as the main technology for development of the Moldavian energy system. It is concluded, that construction of gas engine cogeneration plants with power in the range from 3 to 10 MW in many Moldavian towns and modernization of the Central Heating and Power Plants in Kishinev and Balti will lead to the creation of the perfect energy system for Moldova. As a result, security of energy supply in Moldova will be increased; transportation and distribution losses will be reduced. In addition, it allows putting down the heat energy tariff, improving the standard of living of Moldavian people and competitive ability of Moldavian wares. Later the gas engine cogeneration plants can be transformed in the modern three-generation plants, and supplemented by the best high efficient renewable fuels technologies

Influence of electric fields on mass transfer in gas-liquid media

The rectification and evaporation processes and also the intensification by an action of the corona, barrier discharges or EHD dispersion of lyquid have been investigated. The aim is to determine the possibilities of electric discharges according to the mass transfer action on the rectification in the dispersion conditions. First the mechanisms of mass transfer intensity change at rectification in the conditions of electric charge realization in the gas phase or EHD dispersion of liquid have been obtained. The in the main new high effective methods and apparatuses have been developed, they permit to essentially increase and improve the basic indices of technological equipment; the ranges of optimum regime and desing parameters have been selected. The method of performing mass transfer processes and apparatus have been introduced at rectification of the vine alcohol. The introduction effectiveness at rectification of secondary wine-marking products for Research Enterprise of Agricultural-Production Association "Yalowen" is 20000 roubles/year, for "Prosozstroy" - 1200000 roubles. Area of application: rectification, evaporation, adsorption in wine-marking, alcohol, liqueur-vodka productions and other technologies of food industryAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

ONE OF THE WAYS TO RISE THE EFFICIENCY OF THE KISHINEV TOWN HEAT AND POWER STATIONS

Methods to rise the efficiency of fuel using at town heat and power stations are discussed in detail. It is shown that application of hot water/exhaust absorption chillers allow to use heat energy surplus especially in warm season. As the results, the consumption of heat energy from the power stations is more constant during the year, the efficiency of fuel using is higher, and economics is better. Different technological schemes are discussed in detail
