The article contains the mathematical model of cooling shaving boards, which was made with small-toxic resins; it make possible to determine the length of the cooling boards on given temperature in every moment. Suggested the equipment for cooling shaving boards, which will make it possible very effectively cool the boards

In the article features of implementation and development of financial innovations in commercial banks activity are considered, objective need of their application for banking is proved
The problems of quality of services and issues of cost management on the quality of services are analyzed in the article. Special attention is paid to companies that provide services of audit, consulting, examination and development of measures to improve fire safety and a labour safety at companies. Problems of quality of services are classified. Methods of multidimensional systems analysis of the problems of the quality of services are offered
We have proposed a cutting segment for commercially available feeders; we have also presented the design scheme of the cutting edges and the angle of segment installation on a working body
Chin sativa grain yields on the black-earth soils in Rostov region are studied. Recommendations about applying of mineral fertilizers with symbiotic nitrogen fixation are given
The article presents the violation of water protection zones. The change in soil fertility. Transparency is linked to the nature of the coating beaches and surface destruction. Surface runoff depends on the vegetation cover. The destruction of vegetation (deforestation, excessive grazing, fire), incorrect plowing surface (along the slope) and tillage farming without following the rules lead to increased erosion, local soil erosion, gully erosion and the rise to an increase in turbidity of rivers. Environmental effectiveness of forest plantations. Prevention of pollution and siltation of river. Improving the sanitary condition of the territory
In the article, the results of the analysis of the two-layer pole-switching winding, containing considerable amplitude of lower harmonics are shown. We have also investigated the effect of lower harmonics on the start of an induction motor
In the article, the review of the results of the research of blood supply of the thorax of large horned livestock, a pig and a dog is given. Blood supply and outflow of blood from biologically active spots of the thorax are discussed
The results of study of groups and forms of iron compounds in leached chernozemic soils of Western Ciscaucasia for three crop rotations according to scheme grain-grass-hoeing are presented. With long-term use of leached black soil in terms of Agrigento there is a substantial change in the contents of the various groups and iron compounds. On the non-fertilized variant of rotation, the total content of this element in the 0-20 cm 21-40 cm soil layer by 69.4 and 66.5% of silicate and by 30.6% and 33.5% free group of compounds of iron. The applied system of fertilizer crop rotation helps reduce the silicate and increase of free group its compounds. In leached black soil a group of desilicated iron in the 0-20 cm layer 24.8 % presents crystallizability and to 75.2% amorphous compounds, 21-40 cm layer, respectively, 26.2 and 73,8 %. Under the influence of fertilizers we have noticed increasing of amorphous and reducing the number of cristallizing forms of the compounds of this element the soil. The number of different groups and forms of iron compounds in leached black soil with systematic use of fertilizers in crop rotation is determined not by the size of introducing this element as impurities, and processes such as the alienation of iron with additional derived products, increase its mobility in the soil due to a shift in the reaction of the soil solution, changes in fractional-group composition of humus. Diagnostic criteria state of iron in the soil are leached quantitative ratio of the content of the various groups and forms of the compounds of this element
