SPECIES DIVERSITY OF LONG GOURD LAGENARIA SICERARIA (MOLINA) STANDL
DescriptionThe issues of international spread of fruits of long gourd lagenaria and the introduction of it in culture are considered in the article. We have shown how to use it as a vegetable crop and considered varietal diversity of this species. The biological characteristics of lagenaria cultivation as vegetable plants, including peculiarities of the reproductive system have been marked. We have also considered the issues of cultivation and distribution of long gourd lagenaria (zycca) for food

OVERREGULATION OF OVERFLOWS OF PLAIN KRASNODAR TERRITORY
DescriptionSurface sewer depends on vegetable cover. Deleting the vegetable cover (due to cutting, overindulgent fall out live-stock, fires), wrong plowing up of surfaces (along declivity) and processing of ground without observance agronomic rules bring reinforcement of erosions, local soil washout, origin gully erosions and to increase the turbidities of the rivers

QUESTIONS OF PROTECTION OF SOIL IN THE AGROLANDSCAPES
DescriptionBalance of heavy metals in the topsoil describes their content at admission and take-out for a specific period of time. Sources of heavy metals in the soil are their admission with atmospheric precipitation, sowing material, dust, organic and mineral fertilizers, as well as other components. Take-out of elements from the soil is taken into account with a crop (grain yield of green mass, roots, etc.), as well as with the removal of water and wind erosion

SORTIMENT TABLES FOR ESTIMATION OF ARTIFICIAL ORIGIN OAK FORESTS IN THE LOWER VOLGA REGION
DescriptionThe article proposes a system of regression equations for estimating industrial wood size by categories and varieties of commercial trunks of oak plantations in the Lower Volga region. The authors developed a table of logs for the taxation of trees and forest stands of oak

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

01.00.00 Physical-mathematical sciences
DescriptionThis article briefly reviews the classical concept of functional dependence in mathematics, determines the limitations of this concept for adequate modeling of reality and formulates the problem, consisting in search of such generalization of the concept of func-tions, which is more suitable for the adequate reflec-tion of causal relationships in the real domain. Also, it discusses theoretical and practical solving the prob-lem, consisting in: (a) we suggest the universal method of calculating the amount of information in the value of argument about the meaning of the function, i.e. cognitive functions which is independent from the subject area; b) we offer software tools: Eidos intelli-gent system, allowing in practice to carry out these calculations, i.e. to build cognitive functions based on a fragmented noisy empirical data of high dimension. We also offer the concepts of nonreducing, partially and completely reduced direct and inverse, positive and negative cognitive functions and the method of formation of reduced cognitive function, which is a generalization of known weighted least-squares meth-od on the basis of observation the amount of infor-mation in the values of the argument about the values of the functions accounting

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)

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

COSMOLOGY OF INHOMOGENEOUS ROTATING UNIVERSE AND REALITY SHOW
01.00.00 Physical-mathematical sciences
DescriptionOn the basis of the solutions of Einstein we have proposed universal metric describing the properties of an inhomogeneous rotating universe. It is shown that in the case of space-time metric of negative curvature, the field equations are hyperbolic, parabolic or elliptic type, depending on the equation of state. An equation for the general state of the species, describing the emergence of matter, as the aggregate state of dark energy proposed

HEEDING OF HETEROGENEITY OF ENVIRONMENT WHEN CALCULATING A MAGNETIC FIELD
01.00.00 Physical-mathematical sciences
DescriptionThe formula for definition of magnitude and direction of secondary sources of a field as surface currents for the registration of heterogeneity of environment is found. We have shown that it is possible to solve non-linear field problems, using the mathematical deduc-tions shown in this article
