TRAINING OF PEDAGOGICAL EDUCATION MASTERS: PRACTICE-ORIENTED MODEL

Purpose: The article deals with the problems of training, attraction, and retention of teachers of the required qualification in educational institutions. Methodology: This problem is analyzed at the regional level in the context of reforms in the higher education system, the transition to a two-level model in accordance with the provisions of the Bologna process. Result: Based on the analysis of open data in the work it is stated that the shortage of teachers in the region (Samara region) is significant and has a negative impact on the educational process of educational institutions; it cannot be compensated exclusively by bachelors of pedagogical education, issued by pedagogical universities. Applications: This research can be used for universities, teachers, and students. Novelty/Originality: In this research, the model of training of pedagogical education masters: practice-oriented model is presented in a comprehensive and complete manner

Research and Control of the Purity of Production Hydrogen with a High Degree of Purification When Applying the Electrolysis Method of Production

We conducted experimental studies aimed at determining the purity of hydrogen obtained at the electrolysis installation made by Hydrogen Technologies (Norway) at the pipe plant Centravis Production Ukraine in the city of Nikopol, Ukraine.It was established that the determination of hydrogen purity and the degree of its purification from impurities (nitrogen) in microconcentrations involves two stages of measurements:− research into the presence of nitrogen in the samples of production hydrogen in the microconcentrations of [[N2] 0.001−0.01 % (rough estimate);− research into the presence of nitrogen in the samples of production hydrogen in the microconcentrations of [[N2] 0.001−0.01 % (fine assessment).We determined that the purity of production hydrogen, obtained during research, was 99.9±0.1 %. A given value for purity does not match certification indicators for purity of production hydrogen claimed by the manufacturer to equal 99.9999 %.We analyzed the reasons for the mismatch between the purity of obtained hydrogen and claimed characteristics. A detailed analysis revealed that the possible cause of high nitrogen concentration in hydrogen is the worn piston rings in the stage of compressor pistons, which causes the penetration of nitrogen in microconcentrations into production hydrogen. Piston rings in the compressor's stage were replaced. Repeated studies into purity of production hydrogen indicate that the purity of production hydrogen amounted to 99.99±0.01 %, which corresponds to the hydrogen of grade A
