PARKOUR AND RECREATIONAL ACTIVITIES

Recreation philosophy is human ability to relax applying various games and activities, where a game or activity has some purpose, which we should know and understand how to achieve it. Parkour is a movement, form of training, a way of getting it, the art of moving from point A to point B with your own body as a means in as fast, efficient and controlled manner as possible based on your own circumstances. It is completely free from competitions, competitions or other forms of rivalry. Recreation is for people to restore from everyday work routine and stress. Practically people perceive this essence of recreation which gives us a possibility to relax and creates emotions of happiness. Parkour is an art that helps you pass any obstacle to go from point A to point B using only the abilities of the human body. One of recreation and parkour kinds is outdoor activities, which means different open-air activities in nature. Outdoor activities have a physical, mental, emotional and even educational effect on a participant. Recreation and parkour activities are not organized like competitions, to participate in them there are no rules made. People who go in for recreation outdoors need only space on the land, water or in the air. It is an activity which allows an individual to renew interacting with the nature in cities and villages, as well as in virgin nature territories. What separates them from parkour is that they contain more acrobatic and spectacular movements and where there may be an assessment in the performance. Recreational activities and parkour activities have many symbioses, sometimes we can Sayed recreational parkour (parkour of basics) for everyone. We are getting great emotions and physical well-being.

Нанесение микропокрытий конденсацией с ионной бомбардировкой как метод для увеличения износостойкости инструмента

Высокотвердые покрытия обеспечивает увеличение стойкости режущих инструментов. Эффективным и относительно простым методом, с точки зрения оборудования, являются устройства, основанные на процессах сильноточного низковольтного разряда, развивающегося исключительно в парах материала электродов. Таким является способ КИБ (конденсация с ионной бомбардировкой).Причиной потери режущих свойств режущего инструмента являются: износ и появление наклепа. Увеличить микротвëрдость и тем самым и износостойкость и противостоять появлению наклëпа помогают микропокрытия режущего инструмента из высокотвердых материалов. Один из способов получения таких покрытий – КИБ

Efficiency of EM Induction Permanent Magnets Pumps

The efficiency of EM induction pumps on permanent magnets are defined by their main constructive parameters the optimal values of which, in its turn, are depending on specified nominal productivity of pump (developed pressure head and provided flow rate) and its operating conditions, mainly temperature of liquid metal being pumped. The influence on the efficiency of pumps of such main parameters as magnetic field strength, geometry of magnetic active system and channel of pump are considered

Efficiency of EM Induction Pumps with Permanent Magnets

The efficiency of EM induction pumps with permanent magnets is defined by their main constructive parameters, the optimal values of which, in turn, depend on the specified nominal productivity of the pump (developed pressure head and provided flow rate) and its operating conditions, mainly, the temperature of a liquid metal being pumped. The influence of such main parameters as the magnetic field strength, geometry of the magnetic active system and the pump channel on the efficiency of the pumps is considered. Introduction.

Characteristics of Disc Type Electromagnetic Induction Permanent Magnet Pump

The pressure, flow rate and power characteristics of disks type electromagnetic induction pump on rotating permanent magnets (PMP) have been measured on In-Ga-Sn loop for different gaps between magnetic disks. Gained experimental data base is very important for design and evaluation of parameters of disk type PMP as theoretical calculations of parameters of such type of PMP is very difficult task due to non-uniform distribution of magnetic field and, consequently, of induced electromagnetic forces in radial direction. Along the radial direction also other important governing parameters defining the efficiency of pump (such as pole pith length and velocity of generated alternating traveling magnetic field) have non-uniform distribution. Magnetic field distribution between poles for different gaps between magnetic discs was measured. From experimentally measured pressure, flow rate and power characteristics (heat losses in liquid metal layer in the channel of pump and in electrically conducting walls of the channel of pump made from stainless steel) the averaged value of effective magnetic field was determined, which is the main parameter defining the efficiency of pump used at first order evaluation of PMP parameters. The results of measured efficiency of the pump depending on the distance between magnetic discs are very important at practice allowing to choose the gap between discs (which can be varied) to ensure needed protection of permanent magnets from heat radiation depending on the operating temperature of liquid metal in the channel of pump

Comparison of Electromagnetic Pumps with Permanent Magnets with other Electromagnetic Pumps

Many science and technique fields use liquid metals. Every time when it is necessary to operate with liquid metals methods of magneto hydrodynamics (MHD) are the most suitable because liquid metals are good conductors of electricity. Liquid metals can be easily pumped using electromagnetic pumps. Electric current interacts with magnetic field and generates electromagnetic force, which makes liquid metal move. Electric current flows in liquid metal. Therefore electromagnetic pumps do not have direct contact with a pumped medium – there is no need in gaskets, channel of the pump is a hermetic construction. Electromagnetic pumps are used in many fields related with liquid metals. Most important examples are metallurgy and nuclear energetic
