The article presents the design of hand mowers with cutter, consisting of the rotating screw and stationary segments. It also shows the results of experimental studies to determine the rational angle turns of spiral screw
The article deals with improving the reliability of data collection and storage of historical data. Investigated the reliability of collecting historical information, the technique, allowing on the basis of general logical and probabilistic methods to identify the most important elements to increase the reliability of which will sig-nificantly increase the reliability of the whole system
In the article the technology of obtaining carbide steel with hot punching porous billets produced by shock compaction, based on no form powders is described, the structure and properties of the obtained composite material are studied, the parts with enhanced mechanical properties are presented
The article has analyzed the state of the delivery process of mineral fertilizers to agricultural producers
The combined method of formation of the “Steel - superficial of materials with effect of memory of the form on the basis of TiNiCu” composition, which includes mechanical activation of powder, the high-speed gas-flame dusting, the subsequent thermo-mechanical processing is considered. The operating parameters are defined and the optimum modes of processing providing formation of the layers with nano-sized structure are recommended, chemical and phase composition of which corresponds to the shape memory effect
We have presented the program, methodology and the results of the experimental research of the functioning of a complex for climate control of beehives
We have presented a methodology for the optimization of technical parameters of the complex based on a solar system combined with a wind generator according to the criteria of efficiency and consumption of materials
The results of the effect of the electro dialysis treatment on the composition and properties of salt whey are presented. The main regularities of the demineralization process of salt whey and its efficiency are determined
Solar collectors of helio water heater with ramified surface were developed. We have made an energy estimation of helio unit construction and enhancement of the efficiency of its work because of multiple reflections of solar fluxes
We have made energy estimation of absorbed solar fluxes with a glance of diffuse insolation which passes through double- glazing unit to the right-angled planar radiator. While designing the model it was conceded to assume that direct solar radiation is the radiation of a point source
