Description
The research results on regeneration activity of wilding cuttings of phylloxeraresistant varieties of grapes influenced by heteroauxin treatment are analysed in the article. The preliminary studies were held in All-Russian research institute of viticulture and wine-making of Ya.I. Potapenko using cuttings of 3 grape varieties – Berlandieri x Riparia Cober 5bb, Riparia x Rupestris 101-14 and Berlandieri x Riparia CO-4. The cuttings were soaked during 48 hours in 0,005 % heteroauxin and were implanted in sand in adjustable conditions of temperature, humidity and aeration. In 2012-2013 experiments were continued in Kuban State Agrarian University. The varieties Gravesak, RSB and Berlandieri x Riparia Teleki 5C were added to the experiment. Three-items buds were shooted in damp steamed sawdust in a film hothouse. In preliminary researches application of heteroauxin has allowed to increase root-growing by 20,3-40,0 %. The greatest increase of root-growing (40 %) was observed on variety СО-4, that is characterized by the weakest potential rhizogenesis activity, and the least (20,3 %) on control variety Cober 5 bb. Next researches show that treatment of cuttings basal ends by 0,01 % heteroauxin activated their regeneration process, that was expressed in: increase in sprouts length – variety 5 C, 101-14 and Gravesak by 23,1- 157,6 %; increasing of cuttings root-growing from 16,7 % on variety 5C to 60,0 % on variety Cober 5 bb, the quantity of cuttings with not fewer of 3 roots from accordingly 13,0 % to 54,7 %; increasing of roots from 0,7 on variety СО-4 to 2,7 on variety 101-14 or in 1,7-2,7 times. The application of heteroauxin on variety RSB did not show positive results, because of the variety peculiarities

FASCIATION IN NATURE AND IN EXPERIMENTS
DescriptionThe phenomenon of fasciation on the example of higher plants was considered. The effect of fasciation on the various particularities of plants has been shown. The numerous examples of the different groups of plants with fasciation bodies are given. We have demonstrated that the phenomenon of fasciation is more common for cultivated plants than for wild. In most cases, fasciation is considered as an exceptional phenomenon. A number of authors have distinguished fasciation to inheritable and non-inheritable. The first is caused by internal reasons. The second is the influence of external factors such as insect damage, injury, weather conditions. The number of regularities was installed: reproductive bodies of plants fasciationing more often; thermophilic forms are more likely to be fasciation. The images of different cultures with fasciation parts are given. We discuss using the introduction of the term ”connаtions” as morphological abnormalities. Fasciation can be considered as a marker trait for the cause of this phenomenon with violation of ecological situation. The plants with morphosis, including fasciation of the certain parts of bodies, can act as indicators of environmental pollution. The study of the phenomenon of fasciation in higher plants can be regarded as a method of breeding for large fruit size. From one side, to establish the adaptation abilities of newly created genotypes. Thus, the phenomenon of fasciation has affected many areas of science. On the other side, it is proof of the violations caused by environmental factors. On the other hand, it is hereditary reasons, and can also serve as a model for studying morphogenesis

Description
The present work describes the chemical synthesis of poly-N,N-diallyl pyrrolidinium bromide and polyN,N-diallyl morpholinium bromide - high-molecular compounds containing quaternary nitrogen atoms, which included in two five- and/or six-membered heterocyclic rings. These polymers are perspective modifiers for industrially produced anion-exchange membranes, the use of which should significantly improve the resistance to degradation of the membranes at over-limiting current regimes. The structure of obtained polymers was characterized by FTIR, 1H and 13C NMR spectroscopy. The optimal reaction conditions, which increase the yield of desired products, were defined. It is shown that is preferable to use 1-butanol as a solvent and benzoyl peroxide as an initiator

DescriptionClassic quantitative measure of the reliability of the models: F-measure by van Rijsbergen is based on counting the total number of correctly and incorrectly classified and not classified objects in the training sample. In multiclass classification systems, the facility can simultaneously apply to multiple classes. Accordingly, when the synthesis of the model description is used for formation of generalized images of many of the classes it belongs to. When using the model for classification, it is determined by the degree of similarity or divergence of the object with all classes, and a true-positive decision may be the membership of the object to several classes. The result of this classification may be that the object is not just rightly or wrongly relates or does not relate to different classes, both in the classical F-measure, but rightly or wrongly relates or does not relate to them in varying degrees. However, the classic F-measure does not count the fact that the object may in fact simultaneously belongs to multiple classes (multicrossover) and the fact that the classification result can be obtained with a different degree of similarity-differences of object classes (blurring). In the numerical example, the author states that with true-positive and true-negative decisions, the module similarities-differences of the object classes are much higher than for false-positive and false-negative decisions. It would therefore be rational to the extent that the reliability of the model to take into account not just the fact of true or false positive or negative decisions, but also to take into account the degree of confidence of the classifier in these decisions. In the intellectual system called "Eidos", which is a software toolkit for the automated system-cognitive analysis (ASC-analysis), we use initially proposed by its developers measure of the reliability of the models, which is essentially a fuzzy multiclass generalization of the classical F-measure (it is proposed to call it the L-measure). In this article, L-measure is mathematically described and its application is demonstrated on a simple numerical example

MANAGEMENT OF THE FINANCIAL AND THE ECONOMIC STATE OF A COMPANY USING A MATHEMATICAL MODEL
01.00.00 Physical-mathematical sciences
DescriptionThis article focuses on the mathematical modeling of evaluation of financial and economic activities of a company and on definition (based on this model) of such balance settings (line F1 and F2) which would make financial-economic indicators of the activities of the organization optimal, and the total cumulative score was the maximum. The knowledge and the use of the optimal parameters of the balance will allow the managers to plan strategy for the future development of the company. The article analyzes the dependencies of each of the 15 basic indicators (profitability, turnover, financial stability, liquidity and solvency) of financial and economic activity of the organization on the balance parameters. The optimal values of the parameters of the balance and the main indicators of financial and economic activities of the organization have been found. We have also built a mathematical model of optimal control of financial and economic indicators in the form of a problem of mathematical programming. For example, for the company called "Nika" it is shown the possibility of improving estimation of financial and economic condition of the organization. Knowledge of the optimal parameters of the balance will allow the managers to plan strategy for the future development of the organization. To solve this problem we have used the method of generalized reduced gradient implemented in Excel, with which there was found a maximum of the objective function for the article restrictions. The article describes the analysis algorithm of the optimization problem. A common assessment was carried out in stages, based on the calculation algorithm of sequentially improved target functions
