MATHEMATICAL METHODS OF CLASSIFICATION THEORY
01.00.00 Physical-mathematical sciences
DescriptionThis article gives a review of mathematical methods of construction and using of classifications. The main approaches to solving the problems of cluster analysis and grouping are discussed. We have also proposed global and local natural classification criteria. The methods of discriminant analysis (diagnosis, pattern recognition with the teacher) are discussed in connection with the construction of generalized indicators (ratings)

TRACE ELEMENTS AND HEAVY METALS IN WATER AND BOTTOM SEDIMENTS DRAINAGE NETWORK DAGHESTAN
06.00.00 Agricultural sciences
DescriptionIn the main collectors in the North-West Caspian we have found the concentration of priority chemical elements: in water - Zn, Cu, Mn, Co, B, Mo, Cr, Ni, Pb; in sediments - Zn, Cu, Mn, Cr, Ni, Pb. It was found that a common and characteristic feature of drainage water is a low concentration of these elements investigated (except Mn, B, Pb). In the bottom sediments collectors content of gross forms of Zn, Cu, Mn, Ni, Pb and mobile forms of Zn, Cu was below the MRL and the content of the gross forms of Cr and Mn mobile forms was a little higher

MODEL OF MANAGEMENT OF ACCOUNTING OF THE INSOLVENCY PROCESS OF A COMMERCIAL ORGANIZATION
DescriptionIn the article we have considered in detail the questions of ratios of the economic categories of "insolvency" and "bankruptcy". The model of management of accounting of "insolvency" is considered. Introduction in accounting of the poor debtor of the structured book of accounts is offered

MODERNIZATION OF ASSORTMENT OF TABLE GRAPES FOR FARMERS AND CROFT VITICULTURE
06.00.00 Agricultural sciences
DescriptionThe article highlights the issues of improving the assortment of table grape plantations for use in the farms and croft forms of management. Brief presentation of results of the five-year study of 12 table grape varieties in industrial environments for their cultivation: in the OAO AF of "Juznaja", OOO "Phanagoria-Agro" training field "Kuban" and branches of the Department of Viticulture Kuban State Agricultural University: Citrine, Helios, Bogatyanovsky, Anthracite, Dolgogdanij, Preobragenije, Academic K, Rochefort K, Libya K, Kubattik, Nizina and Chrysolite. These varieties are the basis of modern conveyor of table varieties and are recommended for introduction in the State register of breeding achievements of the Russian Federation in all regions of our country

Description
Correlations between values of the differences of first potentials ionization of atoms and molecules (ΔE) and valency angels α for three coordinated molecules of types ЭХ3 (Э=N, P, As, Sb are carried out; X=F, Cl, Br, I, CH3), and also ЭХ2 (Э=O, S, Se, Te; X = CH3, SiH3, GeH3) are described in this article. It is shown, that the entered value ΔE can serve as additive measure of change of the valency angle α in the basic and raised stances. We have also established that the functional dependences correlate with changes in the of hybridization of orbitals and the R parameters characterizing the interaction of electronic pairs near the central Э atom

06.00.00 Agricultural sciences
DescriptionIn this article the influence of agrotechnologies of cultivation of field cultures on soil indicators and distribu-tion of heavy metals on the horizons of the black leached soil is considered. Regularities of distribution of gross and mobile forms of manganese, zinc, lead, cobalt, copper and cadmium on the genetic horizons of the black leached soil of the Azov-Kuban lowland are revealed

GENERAL RELATIVITY AND METRICS OF INHOMOGENEOUS ROTATING UNIVERSE
01.00.00 Physical-mathematical sciences
DescriptionThe metric of inhomogeneous rotating Universe is discussed. There are examples of universal metrics obtained in Einstein's theory of gravitation. On the basis of solutions of Einstein’s equation we have proposed universal metric describing the properties of galaxies, groups and clusters of galaxies in inhomogeneous rotating Universe
