Multifrequency dial sensing of the atmospheric gaseous constituents using the first and second harmonics of a tunable CO2 laser radiation

The results of field measurements of concentration of some gaseous components of the atmosphere along the paths, in Sofia, Bulgaria, using a gas analyzer based on the use of a CO2 laser radiation frequency-doubled with ZnGeP2 monocrystals are presented. The gas analyzer is a traditional long path absorption meter. Radiation from the tunable CO2 laser of low pressure and from an additional He-Ne laser is directed to a colliminating hundredfold Gregori telescope with a 300 mm diameter of the principal mirror. The dimensions of the mirrors of a retroreflector 500 x 500 mm and a receiving telescope allow one to totally intercept the beam passed through the atmospheric layer under study and back

Scientific-theoretical background the organization of geobotany employees of the micro enterprises sport and recreation sector

The relevance of the research problem due to the needs of the labor market, terms of developing economy of micro-entrepreneurship in sport and recreation sector and the demands of the subject of labour activity to professional training without discontinuing work. The purpose of the article is to understand the current issues aspects of pedagogical learning situation of a potential employee an experienced professional when using the internal resources of micro-enterprises. A leading approach to the study of this problem is systematically-activity, which allows to represent the process of professional learning in conditions of the micro-enterprise as a system activity of subjects for the development of professional competence of the employee sports and recreation sector. The results of the research showed that the process of training and professional interaction of the micro-enterprise employees to be effective if educational-vocational. interaction of the micro-enterprise employees will be considered as a productive mutual agreed actions of subjects of labour, aimed at solving educational and professional problems in the process of joint labour activity. The article can be useful to researchers of the problem of industrial education in the current socio-economic conditions, from a practical point of view - chiefs of micro-entrepreneurship in sport and recreation sector. © 2016 Andruhina et al

Formation of a microcomposite structure in the surface layer of yttrium-doped titanium

Surface layers containing oxides and carbides of titanium and yttrium are prepared by the electroexplosive doping of titanium with yttrium. The subsequent electron-beam irradiation leads to dispersion of the structure to a nano- and submicron state. The formation of two types of eutectics is revealed using scanning electron microscopy. The eutectics enriched in titanium and yttrium have a globular and plate-like shape, respectively. The formation of a modified surface layer (enriched in yttrium, carbides and oxides of titanium and yttrium) leads to a threefold increase in the microhardness of the titanium, a more than twofold decrease in the friction coefficient of the doped layer, and a more than 2.8-fold decrease in the wear rate

Project approach to training teachers for secondary vocational education

При проектном подходе к подготовке педагогических кадров для среднего профессионального образования изменяются взаимоотношения между заказчиками – учебными заведениями СПО и профессионально-педагогическим вузом, отвечающим за подготовку квалифицированных педагогов профессионального обученияThe design approach to the preparation of teachers for secondary vocational education changed the relationship between customers – educational institutions of secondary vocational and vocational-pedagogical University responsible for the training of qualified, meeting the requirements of the act, teachers of vocational trainin

Structure phase states formation of Ti-Y surface layer by electro explosion and electron-beam treatment

A titanium-yttrium composite surface layer is formed on pure titanium surface by electro explosion and electron-beam treatments. The composite consists of titanium-rich and yttrium-rich eutectic microstructures. Both eutectics are in non-equilibrium state with their chemical constitution deviation from that in equilibrium phase diagram. The surface layer increases the surface hardness by three times, decreases the friction coefficient by 3 times and reduces the ware rate by 4 times in comparison with that of the surface of pure titanium
