A NEW APPROACH TO THE STUDY OF THE STABILITY OF CONCLUSIONS IN THE MATHEMATICAL MODELS
01.00.00 Physical-mathematical sciences
Description
We have proposed the general scheme for studying the stability of the conclusions obtained by mathematical methods and models regarding tolerance deviations of the original data and background models. The concrete problems of stability are discussed: towards a change of data, its size and distributions, to allowable transformations measurement scales, to the temporal characteristics (time of start of the project, the planning horizon). Reducing the uncertainty can be conducted by changing the type of data, i.e. with the aid of the transition to non-numerical data. The models of concrete management processes of industrial organizations are considered on the examples of stability characteristics of investment projects to change the discount factors and in models of inventory management to change in the coefficients of the model and batch size production

PROBABILISTIC-STATISTICAL METHODS IN GNEDENKO’S RESEARCHES
01.00.00 Physical-mathematical sciences
Description
We analyze the probabilistic-statistical methods in the researches of Boris Vladimirovich Gnedenko – the academician of Ukrainian Academy of Science, which are very important for the XXI century. We have also discussed the limit theorems of probability theory, mathematical statistics, reliability theory, statistical methods of quality control and queuing theory. We give some information about the main stages of scientific career of B.V. Gnedenko, his views on the history of mathematics and teaching

NEGATIVE SIGNS OF PLURALITY OF PERSONS IN CIVIL LAW
Description
In the article we investigated various legal phenomena similar to plurality of persons in civil law, but are not, at the first time in a civil law science. The author considers the plurality of persons with similar legal phenomena to identify the characteristics of the phenome-non of legal plurality of persons in civil law

REGULATION VALUE IN THE CASE OF ALEATORY CONTRACTS
Description
In this article we define the place of the case in aleatory contracts. The conclusion is that the case in aleatory constructions plays a regulative role in the relationship of the parties. Regulatory functions in the case of aleatory contracts are manifested in the fact that the legal consequences of the transaction and its economic results determined random event, which is designed to allow the outcome of the transaction

Description
This article is written in connection with the anniver-sary of 100-th issue of the Scientific journal of Kuban state agrarian University. This event suggests the pos-sibility of studying the dynamics topics of research for publication in the Scientific journal of Kuban state agrarian University. This issue is described in the arti-cle. The instrument for this study was applied auto-mated system-cognitive analysis (ASC-analysis) and software tools - Universal cognitive analytical system "Eidos-X++"

GENE POOL OF INDIGENOUS GRAPE VARIETIES AND INTRODUCENTS IN ABKHAZIA
06.00.00 Agricultural sciences
Description
This article provides an overview of results of the conducting surveys on screening and saving gene pool of indigenous grape varieties in the Republic of Abkhazia, which contributed to detection and identification of the 15 previously described in the literature of Abkhazian native grape varieties

01.00.00 Physical-mathematical sciences
Description
The work presents the calculation on the basis of magnetic circuits of magnetic field induction in the "water" gaps of the device for activation of water with alternating magnetic field of industrial frequency. We have executed the calculations of magnetic inductance of the coil of the device taking into account the thickness of layers of winding current-carrying wires. This allowed experimentally determining - with reasonable accuracy - the value of the relative permeability of the steel used, housing, necessary for the specified calculation of the device in general
