Description
The article is dedicated to the features of the correlations between the indicators of shoot and root growth ability of grape cuttings varieties of Moldova and Vostorg of different lengths, under the influence of the processing them with Norwegian growth regulator - Radix plus. We have found that in the control variants on both varieties there are fairly close correlation connections between the number of shoots, their length and the degree of blooming buds. However, in the advanced options the character of the relationship between these parameters depends on the varietal characteristics manifested in the potential root activity cuttings. For Moldova cuttings which are characterized by high root activity, the use of Radix plus led to some strengthening of the correlations, and for Vostorg (with the weak activity of rooting of cuttings) - to decreasing of the correlations. This fact may indicate that the negative effects of growth regulators on the activity of endogenous hormones in the cuttings of Vostorg varieties, which explains the decrease of rooting of longer cuttings. Processing the cuttings of Moldova with Radix plus led to increasing in the frequency and extension of the correlations between shoot and root growth ability of cuttings. For Vostorg, on the contrary, the use of Radix plus led to the weakening of these connections. The reason for this phenomenon, as is the case with figures of shoot growth ability may be a change in the activity of the endogenous phytohormone influenced by exogenous auxin. Character of correlations identified between indicators of root growth ability of cuttings shows that rooting depends primarily on the hormonal activity of cuttings, number of roots - on cuttings plastic substances, and the yield of cuttings with 3 roots and more - on both of these points

01.00.00 Physical-mathematical sciences
DescriptionIn the article, we have suggested a general mathematical model of non-stationary and non-isothermal process of a binary electrolyte transfer in dilute solutions in an electro-membrane system (EMS), taking into account the joint action of gravitational convection, forced convection and electro convection in potential dynamic mode. This model is a boundary problem for a system of two-dimensional quasi-linear Navier-Stokes equation and Nernst-Planck-Poisson in partial derivatives equation. We have developed a theory of similarity of the process of heat and mass transfer in electro-membrane systems, specifically, in a desalting channel of electro dialysis apparatus, taking into account joint actions of concentration polarization, space charge, gravity convection, forced convection and electro convection. It is shown that the criterion of electro convection does not directly depend on the initial concentration, and, therefore, electro convection occurs at any initial concentration. At the same time, the criterion of concentration convection linearly dependents on the initial concentration, and, therefore, at high concentrations, concentration convection prevails, while at lower concentrations, the role of gravitational convection begins to fall whereas the role of electro convection increases. The theory of similarity of the process of heat and mass transfer in the desalting channel of electro dialysis apparatus built in this work taking into account the joint action of concentration polarization, space charge, gravity convection, forced convection and electro convection is important for engineering calculations, for scaling the results of experiments in an electro-membrane cell for industrial electro dialysis water desalting apparatus

FEATURES OF LOAN COMMITMENTS IN FINANCIAL OBLIGATIONS
DescriptionThe article has examined the legal nature of borrowings. The author carries out a comparative legal analysis of debt obligations in comparison with the obligations arising from the contract of bank deposit, bank account agreement, loan agreement, factoring agreement, the insurance contract, the contract of storage. On the basis of a comparative research of the obligations arising from the loan agreement with the other financial liabilities we have determined the state of borrowings in the financial obligations. The author proves the general nature of the obligation of the loan in relation to other financial obligations. A contract of loan for the purpose of its subject and obligations arising from it is much closer to the lease contract and the loan, rather than to the same insurance contract or bank deposit. Borrowings are different from financial obligations only by the fact that its objects are things that contain generic characteristics, interchangeable and not individually defined, as it is in the case of contracts of property employment and loans. An important difference between the loan agreements from other financial instruments is the fact that in the loan agreement the property is transferred to the ownership and not in the possession and use of the borrower

Description
The article presents the results of the studies on the effect of processing grape cuttings of different lengths with Norwegian rooting stimulator called Radix plus on their regenerative capacity. In the experiment we used two-, three-, four- and five buds cuttings of Vostorg table grape variety, characterized by weak rooting activity. Paraffined and pre-processed by growth regulator, these cuttings were rooted in vessels with water. The studies found that with the increasing length of cuttings we decrease the degree of blooming buds, which is associated with the manifestation of the longitudinal polarity. Processing cuttings with Radix Plus leads to inhibition of blooming buds and shoot growth, which is enhanced by increasing the length of cuttings from two to five buds. The maximum of rooting ability of the cuttings and output with 3 or more was reached by roots of two-buds cuttings. The regularity of these parameters decrease with increasing length of the four buds cuttings with some increase in the five buds; the maximum number of roots was reached by two buds and five buds cuttings. Using of Radix Plus reduces the difference between the rooting on short and long cuttings. The most consistent effect of Radix Plus is the output of the cuttings with 3 roots and more on three buds cuttings, and on the increasing number of roots - in the three- and four buds cuttings. When germinating the cuttings of Vostorg variety in comfortable conditions, without using growth regulators, it is better to use two buds cuttings, and in the case of pre-processing them with Radix Plus – we suggest three buds cuttings

LINGUISTIC DETERMINISM, CUMULATIVE EVOLUTION AND DEVELOPMENT OF SCIENTIFIC KNOWLEDGE
DescriptionThe main purpose of this study is to examine how language and its historically inherited content and structure allows accumulating knowledge and determines the development of the individuals, culture and science. The article shows the theoretical drawbacks of modern "pragmatic turn" in which language is depicted only as a derivate of natural, cultural and cognitive systems. Instead, it is stated that language, in addition to all of the above, have to be considered also as a relatively independent basis and one of the causes that determine individual and social development. For that reason, the study examines the system nature of language, thought and culture, their environmental and social "embeddiness", a close relationship with other sign systems and with various forms of social activities. From that point, theoretical reduction of multiple relations and varying causes in complex ecological and social systems only to bilateral relations of language-thought, language-culture are revised. Particular attention is paid to the role of language in the accumulation and systematization of scientific knowledge and the transmission of cultural traditions. In that context, language is seen as part of the non-genetic inheritance systems, "social a priori" that determines the content and creates conditions for cumulative social evolution. Therefore, it is maintained that the comprehensive studies of language and its significance for culture and science have to embrace within a systems approach both the linguistic and pragmatic "turns"

STATE REGULATION OF ORGANIC FARMING: BASES AND FEATURES OF THE EUROPEAN AND THE U.S. LEGISLATION
DescriptionRegulation of environmental protection in agricultural production is very important at the present time due to the growing trend of deterioration of the environment and public health worldwide. A severe negative impact on the environment is due to productive human activities in agriculture, one of which is soil pollution due to excessive use of pesticides. The implementation of organic methods of cultivation of agricultural crops is one of the ways of improving soil fertility. This trend was established in the EU and the US. In these countries, the sector of organic agriculture was modernized with following parameters: legislation, certification and standardization. In the article the authors analyze the characteristics of European and American legislation on organic production of agricultural products, the process of the emergence and development of this activity, as well as conditions for the formation of normative-legal acts, standards and certificates in the EU and the US. Major adverse effects of the widespread use of pesticides and other intensive methods of agricultural production were listed. We have also substantiated the need for the development of organic agriculture as a real instrument for the development of modern and competitive agriculture in the global food market, taking into account Russia's accession to the WTO. We have analyzed European and American legislation on organic production of agricultural products. The process of the emergence and development of this activity, as well as conditions for the formation of normative-legal acts, standards and certificates in the EU and the US has been revealed. We have also proved the need for the development and improvement of legislative base of the Russian Federation in the field of organic agriculture, certification and standardization, taking into account the experience, as the EU and other countries

Description
The article proposes the updated model of the influence of logs length onto a size of wooden chips produced with the use of a disk chipper. This article focuses on the fact that the length of any of the logs in the process of chipping is reduced. For this reason at the final stage of chipping, any of the logs with a standard initial length of 1.2 m inevitably transform into short logs, for which the conditions of chipping are significantly different from the chipping conditions at the start of chipping. The task of accounting for these changes is reduced to finding a solution of the transcendental equation. The results of numerical simulation indicate a progressing decreasing trend in the bevel angle and increasing in the length of the particles of wood chips with decreasing of logs length. Adequacy of the modeling results confirmed by laboratory tests and production experiment. Measuring linear and angular dimensions of chip real particles showed that the particles of such length may be equal to 7 cm, which is 3.5 times larger than the standard length of 2 cm. The angle of the bevel of the cutting plane of the particle may be 14º, which is approximately three times less of standard value equal 39º- 43º. We also discuss the comparison with the approximate solution, which was published in 2012 year. The article can be useful for specialists of wood-preparatory cycle in the paper industry

Description
A diet of a modern man affects the formation of a healthy lifestyle very highly. It supplies the body with the main and irreplaceable nutrients, mineral components and energy. The Russian Federation population surveys, which were carried out by government agencies of the country show us that there is a lack of many nutrients with high nutritional value. Russian market is gradually stuffed with food products which have high nutritional value. For the maintenance of health, active longevity, and for improving their performance, people must consume their organism with all the necessary nutrients. That's why achieving an optimal balance among the nutrients is one of the important question of vital activity. In this article, there were considered optimization approaches to human diet with considering different types of metabolism and maintain weight with using economic and mathematical methods. Also in this article you can find the calculated values of the daily values depending on your calorie eating plan, anthropometric parameters and energy expenditure. We obtained daily value of calories and distributed basic food components- carbohydrates, proteins and fats, and also we calculate the optimal diet for the results of each type of physique - ectomorph, endomorph and mesomorph
