EXPERIMENTAL RESEARCHES OF THE AEROHYDRAULIC WATER LIFT

abstract 0971403052 issue 97 pp. 759 – 772 31.03.2014 ru 1069
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

HUMUS CONTENT CALCULATION THE METHOD WITH USE OF REMOTE SENSING OF THE EARTH

abstract 0921308044 issue 92 pp. 672 – 682 31.10.2013 ru 1072
In the article, we have made an attempt to develop and calculate a model of humus content estimation in the black leached soil according to remote sensing of the ground. We have presented the model which has a number of restrictions for its continuous use when carrying out soil environmental monitoring of land grounds. It is established, that for calculation of similar model it is necessary to perform the cameral works including selection and the preliminary analysis of fields, including using of contemporary records of Remote sensing of the ground for definition of sampling points, to carry out an assessment of space photo shooting and sampling of soils in optimum terms with the maximum synchronism (cameral work and soil and agrochemical inspection), to make the analysis of the selected samples of soils for humus content with traditional methods, and finally to calculate regression models with use of data of the carried-out space shooting and the agrochemical analysis of soil samples

RESEARCH OF THE TEAMWORK OF WATER AND AIR ENVIRONMENT IN THE CONSTRUCTION OF THE AEROHYDRAULIC WATER LIFT

abstract 0891305009 issue 89 pp. 97 – 116 29.05.2013 ru 1214
In the article, we present the experimental model allowing defining physic and mechanical characteristics of the air at the aerohydraulic water lift. Data of the air compression with the hydraulic compression effect were obtained and compared with calculation sizes. Possibility and efficiency of use of water-air pressure system were estimated

STIMATION OF ECONOMIC EFFICIENCY OF THE METHOD OF CULTIVATION OF RICE WITH THE REUSE OF DRAINAGE WATERS

abstract 0971403053 issue 97 pp. 773 – 783 31.03.2014 ru 1329
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
