POWER SUPPLY UNITS OF OZONE GENERATORS USED IN AGRICULTURAL MANUFACTURING
Description
Numerous studies confirming the effectiveness of the use of the ozone-air mixture in various fields of agricultural production lead to an increase in demand for devices that generate ozone. With the increase in demand, the requirements for these devices also increase. Requirements from customers can be combined in the following series: mobility, ease of operation, ability to smoothly control performance. The solution of these tasks is an important scientific and technical task. This article describes possible options for power supplies for ozone generators, and offers a power supply circuit with the ability to adjust the frequency, the duty cycle and the amplitude of the signal arriving at the discharge gap of the ozonizer. Using this scheme will reduce the mass-size indicators of the ozonizer, thereby increasing its mobility, in addition, it will be possible to accurately regulate its performance and improve efficiency. If necessary, with the help of the proposed scheme, it is possible to introduce the ozone generator into the electric resonance mode, which will allow obtaining the maximum productivity of the ozonator. Thus, the ozonizer, equipped with the proposed power scheme, can be used in various technological processes of the same enterprise

PROCESS MODEL OF MANAGEMENT SYSTEM OF LABOR SAFETY OF A MACHINEBUILDING ENTERPRISE
Description
This article is devoted to the implementation of the process approach in the OSH at a machine building enterprises. The approaches to the construction of process system have been considered, taking into account the open nature of certain system and methodological recommendations developed for QMS processes. Processes of OSH are a part of the general processes system of the machine-building enterprise. However, there is no clear a division of the necessary processes into managerial and main production, in any existing standards, supporting and auxiliary processes. In the article, known schemes of OSH processes are considered and a variant of the scheme is developed which meets all the requirements of the interested parties, influence of the external and internal environment of the enterprise, risks and opportunities. A variant of the decomposition of the process of system functioning with the allocation of subprocesses of the first, second and third levels

Description
The article compares various hypotheses that explain the mechanisms of the influence of the magnetic field with different characteristics on liquids, physico-chemical and biological systems. Physical effects that cause specific biological activity of water (magnetic treatment of water, production of thawed water, degassing, etc.) make water be metastable or non-equilibrium states. Water attracts the attention of researchers as a likely universal mediator in the transmission of electromagnetic field signals to the biological level. Water is involved in a variety of chemical and metabolic reactions, so the question about the ability to change the properties of water and solutions under the influence of fields of different nature: an electromagnetic field with different frequencies, with different combinations of field orientations (parallel constant and variable magnetic field, slope fields, rotating magnetic fields, magnetic fields close to zero and electric fields) arises. At the heart of existing methods for treating liquids lie methods that use the energy of the acoustic and magnetic fields, as well as complex methods of influencing the electromagnetic field in combination with thermal heating, pressure change, etc. The analysis of existing hypotheses about the mechanisms of the influences of fields of a different nature on the treated liquid makes it possible to put forward a hypothesis about the possibility of the joint influence of the acoustic and magnetic fields on the liquid by means of the acoustic and magnetic device

TECHNICAL SOLUTIONS OF AN ENERGY SUPPLYING COMPLEX OF APIARY BASED ON A SOLAR PLANT
Description
We have presented technical solutions of an energy supplying complex of apiary based on a solar plant, which ensure its functioning in the winter. Various aspects of the influence of the snow cover on the functioning of the complex are considered in the article. The favorable effect of the snow cover includes increasing the diffuse insolation, improving the thermal insulation of the building for placement of bees, which protects bee families from fluctuating external temperature. The negative effect of the snow cover includes adherence of snow to the receiving surfaces of solar energy converters, which can lead to decreasing the efficiency of using of photovoltaic modules and solar collectors. Both active and passive methods of combating snow sticking are suggested in article. Passive methods include installation of solar energy converters at an angle close to 90°, as well as their placement on the windward side. The simulation of the functioning of the complex based on a solar plant was conducted for climatic conditions of the Republic of Mari El (the time interval – from 14 October to 14 April, a photovoltaic module area – 1,3 m 2 with installation angles of 72˚ and 88˚). Because of the simulation, we obtained graphs of the changing the power of the photovoltaic module. Active methods include air injection onto the receiving surfaces of solar energy converters and using of heating elements

TO THE APPLICATION OF THE SEVEN TOOLS OF QUALITY CONTROL IN HIGHER MILITARY EDUCATIONAL INSTITUTIONS
Description
The article notes the importance of identifying and taking into account factors affecting the quality of the educational process. To solve these problems the collection, processing and analysis of various data are required. In higher educational institutions, it can be achieved reasonably and conveniently using the application of "seven tools of quality control". Differences between civil and military institutions of higher learning determine not only the features of the educational process, methods for achieving quality of teaching, but also the specificity of the "quality" understanding. This article discusses and explains the use of three of the seven tools of quality education control in the higher military educational institutions. According to the authors, the specificity of these institutions is more close collaboration between the processes of the quality management system (QMS) in comparison with civilian educational institutions. In military academies when the causes of nonconformities in the educational process are eliminated, the processes of the cadets’ "second half of the day" are simultaneously improving. In this regard, the scheme of processes, process maps and other documents of the QMS of the military institution will be significantly different from similar documents of the civil. The forms of checklists proposed in the article, the methods of applying the Pareto and Ishikawa diagrams are of an applied nature
