PROSPECTS OF SMALL HYDROPOWER PLANTS IN THE PIEDMONT AND MOUNTAIN STREAMS
Description
The article reveals the advantages of low energy in comparison with other renewable energy sources. It is shown that broad prospects are visible for small (100 - 1000 kW) and micro hydropower plants (up to 100 kW) when used in the foothill and mountain areas. At the same time, the construction of hydropower plants of sleeve-type has improved the operational and technical characteristics, among other types of small-scale power plants. The article presents main analytical expressions for calculating hydroelectric power generator and it has built graphic dependences for the power generator of pressure and water flow. To improve the performance of small hydroelectric power plants we have proposed using unregulated water turbine and non-contact induction generator in their construction, thus, we could stabilize voltage and frequency directly by the frequency converter. Depending on the requirements of consumers to power supply reliability and electricity quality, we have offered several options for structural and circuit solutions of autonomous systems of electrosupply, made using small hydroelectric power plants. Thus, we can greatly enhance the efficiency of such systems if they are used with other types of renewable sources, such as windfarms or solar power plants

PROSPECTS AND FEATURES OF BIOGASOLINE STATIONS
Description
The article deals with one of the promising areas belonging to energy-saving technologies; it is the introduction of biogasoline stations into agricultural production. The analysis of the application in the world has been shown. To determine the cost-effectiveness of biogasoline stations we have shown the data for the calculation of the potential of biomass: organic waste settlements; animal waste; waste of poultry; crop residues; waste processing industry. We have obtained graphic dependences of electricity generated in the day from livestock and poultry, as well as the number of sunflower, rice, and sugar beets. The table also shows the thermal properties of organic agricultural wastes, allowing increasing the efficiency of calculations to determine the biomass resources. We have considered the schemes of biogasoline stations, a gas turbine power plant and a steam turbine power plant and disclosed the features of their work. To improve the operating and technical specifications of the stations intended for power generation we have proposed using non-contact generators and stabilization of parameters of electric power in their designs to carry out direct frequency converter. We have disclosed the advantages and disadvantages of biogas, as well as the direction of its effective use. It is shown that the use of all the possibilities in the complex of biogasoline stationns (production of fertilizers and motor oil, production of heat and electricity) would improve the efficiency and the payback of investment would be from 3 to 5 years, which is mainly determined by the volumes of biomass

EVALUATION OF THE QUALITY OF EDUCATION OF STUDENTS AND EFFECTIVENESS OF TEACHERS
Description
Modern universities do not have effective techniques for evaluating the quality of education of students and effectiveness of teachers' activity that allows controlling and directing its activities. We have proposed to perform the quality evaluation of students preparation based on the results of intermediate assessments, examinations, and test results of the teachers, who held their classes. The article provides analytical expressions for calculating the quality of the current preparation of students and the quality of education of graduates, the effectiveness of teachers in core activities (educational, methodical and scientific work). In assessing the quality of education, we have considered the learning outcomes, employment potential, i.e. educational and labor activity. The proposed techniques will increase the objectivity of the assessment of the quality of graduates’ education in technical universities and the effectiveness of teachers. This will allow us to make changes in the organization of educational process and the content of working programs of training, educational and methodical and material and technical support, to change the contents and technologies of improvement of qualification of the teaching staff that will contribute to increase demand for graduates in the labor market

TO THE QUESTION OF IMPROVEMENT OF THE EFFECTIVENESS OF UNIVERSITY DEPARTMENTS IN SCIENCE
Description
The article proves the impossibility of interaction of scientific work with educational process to prepare highly qualified specialists, who would be able to solve industrial problems and develop the economy of the country. The scientific results are indicative of the level of qualification of teaching staff, which affects the quality of students. The article defines the structural relationship and the content of the organizational activities of scientific and educational departments of the University, the departments and the deans of faculties. They are aimed at improving the quality of recruitment and training of students, informing about the achievements of the University, establishment of links between companies and organizations interested in the results of scientific research of the University and its graduates. The reviewed activities and structural links with the coordinated work of the structural subdivisions of the University and implementation of the best practice are the basis of progress. They will not only increase the efficiency, including the efficiency of scientific work, but also they will increase the quality of students
