By the method of the dipole moments the connections of (p-XC6H4)3As=N-C6H4-Y series have been examined. The method of the vector-statistical analysis of the dipole moments helped to define the ranges and directions of the moments of (Сар)3As=N-Cар, (Сар)3As=N и N-Cар series. There has been shown that the substitution of the para-assistants X and Y in aromatic groups doesn't lead to an additional interaction influencing the electronic properties of the (Сар)3As=N-Cар group. The comparative analysis of the (Сар)3Ð=N-Cар (Ð=P, As) group moments specifies the essencial shift of the electron density to Сар(N) when replacing atom P to As
In this article, generalization of managerial process by gathering extra means is resulted; principles of management are shown by formation of the extra capital; the concept financial leverage, effect financial leverage and a technique of its calculation is resulted; look-ahead change of effect financial leverage at the expense of influence of optimum structure of the capital of some agricultural organizations of Krasnodar region is calculated
In this work, the example of skidding vehicle passes distribution along a skidding trail is considered. The distribution is determined when vehicle capacity is being decreased in skidding process because of rut depth increasing on the soils with low bearing capacity
The article defines the importance of the problem of investment attraction of agriculture and its assessment. We analyzed the current state of investment activity in agriculture of the Rostov region
The results of development tools and mechan-ism of supplement training system, retraining and extension course for qualified personnel of enterprises and organizations focused on innovation- economy are shown. The article may be useful for economists and other pro-fessionals interested in the formation and de-velopment of company and staff competen-cies
The effect of glue filling of internal voids of the surface tracheids and their relative position in the radial wood surfaces gluing on the strength of adhesive joints is theoretically considered. It is shown that for the maximum joint strength it is necessary that the amount of deposited adhesive provides filling of all cavities tracheids of wood surface and formation of the intermediate layer between the substrates
The article presents the results of the study of the effect of different modes and their structure on the amount of furfural and formaldehyde emitted from beech and oak wood. The recommendations on re-ducing of impact of harmful substances on the envi-ronment are given
The article deals with the concepts of situations that are set by the verb ‘tener’ on a material of Kamilo José Sela work of art. Semantic dominants of constructions with ‘tener’ are defined and analyzed
This article discusses the actual problem of using SSR-markers in studies of the genus Prunus. We have examined the works on the most important cultures of genus, collected and analyzed contemporary literature of the subject. Data of the initial stage of Prunus SSR-based genetic diversity study in the North-Caucasian region has been described in the presented publication
The research work was conducted on the tomato hybrid F1 Мо 755 × L. esculentum var racemigerum (Lange) Brezh. The individual characteristics of the reproductive system of tomato F1 hybrid were studied for their further inclusion into the selection programs. The dynamics of these factors in regard to the clusters in the tomato inflorescence was investigated.
