THE DESCRIPTION OF PROCESS OF WATER GIVING OF THE AEROHYDRAULIC WATER LIFT WITH THE REGRESS EQUATION
Description
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

EXPERIMENTAL RESEARCHES OF THE AEROHYDRAULIC WATER LIFT
Description
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

Description
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
