The paper presents the results of experimental studies on the developed bone degreasing stand. The object of the study is the production of valuable components from organic raw materials. Fractions of cattle crushed to the size of 2.5 mm, 5.2 mm and 10.5 mm were used to identify the effective mode of operation of an electrohydroimpulse installation. Physical and chemical methods of fat extraction are currently not relevant from the point of view of economy, due to environmental damage and labor intensity. In this regard, new effective methods of extracting fat from bone mass are needed. Therefore, the proposed method of extracting fat by spark discharge is an actual and alternative method for today. During the study, an acceptable temperature regime for fat production was obtained. Next, a laboratory stand was assembled, with which you can degrease the bone mass without changing the properties of fat. Experimental studies show that with an increase in the capacity of the capacitor bank in energy storage devices and the length of the discharge gap, the bone degreasing process becomes more efficient. During the study, it was found that at a liquid temperature of 38 °C and a pulse voltage of 25 kV on a switching device of an electrohydroimpulse installation, the degree of fat extraction increases without destroying the morphological structure of bone mass. Using the hexane extraction reaction, we determined the efficiency of fat extraction at a temperature of 38 °C, at which the fat mass from the bones is effectively broken down, and using the UV-1800 spectrophotometer, we determined the amount of protein in the bones before and after treatment. The study also showed that with a capacitor bank capacity of 0.5 uF, crushed to a fraction of 10.5 mm of pelvic bone, the separated fat is 18.7 %, and with constant grinding of the capacitor bank to a fraction of 2.5 mm – 19.4 % [ABSTRACT FROM AUTHOR]

The key goal of the inspection was construction buildings and facilities examination, technical condition estimation, bearing capacity and further running qualification testing. The present research is based on the following complex examination materials: physical and corrosional tear and wear of the ferroconcrete and metal constructions detection; the actual dimension of the cross - section construction elements identification; drawing up defect registers and serviceability estimation. The inspection showed that the technical condition of buildings and facilities is functional on conditions of complete rebuilding maintaining. In further it is necessary to maintain needed fixing in time, as well as to comply with the rules of the constructions technical maintenance. Recommendations on water supply and draining systems restoration are given. [ABSTRACT FROM AUTHOR]
