The completed observations have confirmed the expediency of vertical installation of the all-season electro helio water heater’s collector under certain conditions. In summer, Kv is considerably more than unity. In winter and low season, Кv is nearly equal to unity, which is necessary
The problem of preparing most suitable optimal technical offer for datacenter systems hardware supply using set cover problem method is considered in this article
The article describes the application fields of a low frequency electromagnetic field for the increase the storage period of agricultural products. It also describes the advantages of the use of electromagnetic fields of the extremely low frequency to enhance the seed germination of crops, drying and reducing the microbization of raw materials in the preparation of it prior to cooking or other processing in the production of food. The article presents the modes of influence of electromagnetic fields of extremely low frequencies at the various processes used in the food industry
The experimental data of the study physical and mechanical properties of modified "poor" concrete for road clothing base device has been presented in this article
The article presents the approach to modeling of microprofile felling areas as the bearing surface of harvesting machines and is an example of the model obtained in the study of the behavior of wheeled vehicle on uneven support surface
In this article, we have considered the possibility and the availability of cold plasma technologies application in different branches of industry. We have described the investigations of cold plasma treated water in potato growing technology which will conduct in PetrSU at Agricultural faculty. The basic parameters of the device for water treatment with cold plasma are described. The results of the experimental investigations about cold plasma treated water influence on potato growth and productivity are presented
In the article, we have revealed the efficiency of sown using of fertilizers, the methods and the doses of additional fertilizing on different maize subspecies growing on the leached black soil of Northern Ciscaucasia which are based on studies in central part of the Kras-nodar region in 2008-2010. We have also given the scientifically-based references of increasing productiv-ity of maize
In the article, we have studied the effect of antibiotics on enzyme’s activity of black soil. Introduction of the high doses (600 mg/kg) of antibiotics benzylpenicillin, nystatin) leads to considerable decrease in enzyme’s activity of soils. The class of hydrolyses is most sensi-tive to the action of antibiotics, their activity decreases for 50-70% from control values, the class of oxidore-ductase is least sensitive (10-40%). Antibiotic’s action on enzyme’s pool of soils has the prolonged character
This article shows the lines for the processing of manure. Besides, the equipment which is necessary for the realization of the process is defined
To solve the problems of full-value feeding for pigs, it is offered to use protein-vitamin-mineral additives as a component of rations. It allows increasing live weight gain, average live weight gain and improving feed conversion efficiency per 1kg of live weight gain
