In the article we have presented the results of research of influence of activated mineral fillers on mechanical properties of fine-grained concrete. It is shown that clay and zeolites in mechanical activated condition have increased both early and estimated durability of concrete
THE DESCRIPTION OF PROCESS OF WATER GIVING OF THE AEROHYDRAULIC WATER LIFT WITH THE REGRESS EQUATION
In the article we have considered the experimental installation, for realization of full factorial experiment on research of productivity of the aerohydraulic water lift. The regress equation describing process of water giving of the aerohydraulic water lift has been
received. We have also checked the adequacy of the equation of regress
In the article, we have presented the experimental researches of the aerohydraulic water lift. The influence of the pressure on the aerohydraulic water lift and water giving height on productivity has been researched as well as we have made a multifactorial research of productivity of aerohydraulic water lift. It has been established that productivity of the aerohydraulic water lift depends on the difference between pressure and water giving height. Influences
of diameters of submitting and nutritious pipelines on productivity have been established
The article considers the questions of definition of economic efficiency of the developed method for reuse drainage waters. The size of the economic result with account of ecological factor and cost of building production is defined. The estimation of efficiency of the developed method on following indicators is made: the discounted net profit; the profitableness index; the internal norm of profitableness; time of recovery of outlay
In the article, the following items are represented: mathematical formulation of system including: asynchronous generator with cage rotor, condenser’s for excitation, induction load. Electromagnetic and electromechanical processes of induction motor’s connecting and feeding are described. Equations of voltage stability, equations of current, equations of rotor are used for describing of electricity circuits of generator
This article considers the criteria of the efficiency of means for antierosion processing of soil with reference to industrial-economic conditions of the Kabardino-Balkarian republic
In this article, we have given a short review of scientific bases of designing of blocks and module cars and some perspective works for opening new possibilities of increasing the efficiency of technologies of intensive mountain and foothill gardening
This article considers factors which are necessary for considering at application of the minimum processing of soil. The scheme of power saving processing of soil and the scheme of the minimum processing of soil in a crop rotation with good water penetration are offered
Current state and prospects of development of technical service of machine-tractor forces of agroindustrial complex are analyzed. Basic factors of development concept of technological service are based. They are: quality, repair and technological equipment, documentation and skilled staff
This article studies the influence of various methods of thermal, acoustic and electromagnetic exposure on free lipid content, acid and peroxidation number of oil in sunflower seeds during their after harvesting ripening. We have investigated the influence of traditional and microwave heating on lipase activity of seeds. We
have also founded the most efficient conditions for the rate and the temperature of microwave heating of freshly harvested sunflower seeds and determined their effect on the rate of drying
