ORIGIN, EVOLUTION AND DISTINCTIVE FEATURES OF LANGUAGE AND COMMUNICATION IN NATURE
DescriptionThe article considers current trends and unsolved problems in studies of the origin and evolution of communication in nature. Distinctive features of natural language, its biological, cognitive and sociocultural foundations are revised from the perspectives of new findings in this field. The article also investigates the main characteristics of primal and basic forms of "communication" (e.g. in bacteria and plants). It is argued that to them are more applicable non-representational models of communication, because they are not based on the representation of meanings or the processes of cognition and interpretation. On the example of the acoustic signals of birds and primates it is shown that they have such linguistic features as referentiality, plasticity and sociocultural heritability. Discovery of the faculty, for instance in some species of birds, for a "semantically compositional communication" ("semantic compositionality"), reveals also the presence of the "protosyntax" in animal communication. Considered studies enable to bring together features of communication in nature and natural language and to see the evolution of communication as the more gradualistic process than previously thought. Nevertheless, it is emphasized that there is a need for the development in the modern studies the socio-cultural approaches to communication that take into account the non-genetic inheritance system and the cumulative nature of culture

DescriptionIncreasing the yield of crops is a global challenge posed by the scientists from all over the world. To achieve this goal, we use various methods such as: engineering, agro-technical, agronomic, chemical, physico-chemical and so on. We conducted a theoretical study, which showed that the use of physical and chemical methods of treating seed before sowing has a positive effect on the growth processes of seeds. One of such methods is an ozone treatment, which has established itself as a quality growth stimulator of agricultural plants. But despite numerous studies there is no clear description of the mechanism of ozone effects on seeds. In this article, based on our theoretical study, we have presented a material that allows revealing the positive effects of ozone exposure to the seed. To confirm these theoretical results, we have decided to conduct a pilot study. In connection with what, in this article we have included the materials containing information on laboratory equipment and methods of the experiment. We have also presented measuring equipment and methods of iodine-metric method for determining the concentration of ozone in the ozone-air mixture, exact conformance with calibration gas analyzer which will allow to obtain reliable data on the dose effects of ozone on the grain

DescriptionIn this article we propose a method of determining the share or the significance (weight) of indicators of Beaver and risks R in the portfolio formed by these parameters allowing us to minimize the mean square error evaluating the effectiveness of the portfolio (risk) in the assessment of the financial condition of the companies investigated. The proposed method is the minimization of a quadratic form in variables satisfying lengthy conditions, i.e. the quadratic programming. This technique is implemented using four methods of optimization: analytical method, using built-in function minimization block given, the penalty function method and the gradient method. More so, this technique allows, as shown by the results of the computational experiments, the expert without routine statistical data processing to obtain additional information on the credit worthiness of the investigated enterprise and make a more informed conclusion about its financial condition, which speeds up the decision on granting a loan required by a company. Based on the techniques proposed in this paper, other techniques of assessing the creditworthiness of businesses may be constructed using the results of optimization theory based on well-established applied research methods: Method of evaluating the creditworthiness of Russia, Credit scoring method, the American method, method of Altman and others

ECONOMIC-BIOLOGICAL FEATURES AND EXTERIOR MAINTENANCE OF YOUNG CATTLE IN THE KRASNODAR REGION
06.00.00 Agricultural sciences
DescriptionIn the Krasnodar region there is a unique gene pool of animals both for dairy and meat. To assess the heifers the authors formed five experimental groups of animals, the most common species in the region. The authors studied the main economic, biological and exterior features: live weight, measurements, assessment of the exterior. The studies found that among intensive species with the largest body weight throughout the growing period, in 8-month old Charolais heifers superior Simmental ones at 17.4 kg. In one year old Simmental heifers were 9.2 kg (R˂0,05) ahead of Charolais and in 15 months – 10 kg (R˂0,05). Over the entire period of growth the highest rates of relative growth rates of heifers were obtained by red steppe breed type named Kuban, which had an advantage over the Aberdeen-Angus – 19.1%, Charolais – 5.6%, Hereford – 6.2%, and the difference between them and Simmental weren’t fixed. When growing, the animals become less tall, more stretched, wide and massive. We have noted that during the period of cultivation we had increased indices: stretch (9% – Red Steppe, 13.8% – Charolais, 16.1% – Hereford); chest (5.4% Aberdeen Angus). This reduces the index of long legs of red steppe – 5.6%, 10.9% for Charolais. The study of linear growth of animals confirms that the animal meat breeds of live weight increase was due to the extension of the body and increase the width of the pelvis and chest. Some different facts were observed in heifers of Red Steppe breed. For them, the most characteristic increase in the width of the chest was 1.44 times, as well as increasing the depth of the chest and chest girth behind the shoulders

CREATING THE LOW BUDGET INTENSIVE APPLE ORCHARDS IN THE REPUBLIC OF DAGESTAN
06.00.00 Agricultural sciences
DescriptionIn the conditions of foothill soil-climatic zones of the Republic of Dagestan we have explored the creation of low-cost intensive apple orchards. This work was initiated by the authors in 2011 due to the Republic "Horticulture Development Program for 2011-2016", according to which, it was planned to plant 6,200 hectares of new gardens. However, the experience of gardening in the Republic, taking into account recently prevailing socio-economic relations, subsidized nature of the economic and a chronic lack of funds, shows the riskiness of the creation of high-tech pillar-dwarf plants with the cost of 1-1,5 million rubles per hectare. Inability to overcome quickly the existing problems in the development of the industry sharp gardening at this stage, forced us to seek a way in a single direction - reducing the cost of the creation of apple orchards, while maintaining their high economic efficiency. Theoretical studies were realized as a planting of the apple garden in the district of Karabudakhkent of Dagestan of four perspective late-ripening varieties on the medium growing rootstock in the spring of 2013. The results of the three years of scientific research were embodied in the creation of intensive apple garden on the medium growing rootstock which allow now to make the following preliminary conclusions: 1.It is possible here in Dagestan to create intensive apple orchards, with an estimated yield of 30-40 tons per hectare, on the medium growing rootstock already at a density of 666 trees per hectare. 2. Cost of such a garden, without compromising quality indicators, can be reduced in the current market price of labor and the necessary materials, up to 214 thousand rubles per hectare, with access to the full return of all costs in the seventh year of operation. Such intensive garden, according to common practice, during the period of operation is able to give at least 22 full-weighty harvests and provide a net profit about 6.6 million rubles per hectare, or 236,000 rubles per hectare per year for the entire period of alienation of the land for a garden

06.00.00 Agricultural sciences
DescriptionThe article presents the characteristics of the mechanical composition of clusters, the chemical composition of grape juice and fresh grapes and wine tasting evaluation of three varieties of table. We have identified the following uvologic indicators of clusters of cultivars Flora, Nisina and Anyuta: structure - 90.0; 91.5; 87.3; addition - 8.0; 6.6; 10.8; structural - 6.4; 5.4; 8.1; berries - 17.6; 15.0; 10.4. In the studied berries of grape varieties the mass concentrations of sugars and titratable acids were in the range 18,1-23,5 and 0,73-0,78 g/100 cm3 respectively. The combination of sweetness and acidity causes high taste properties of grapes. In grape berries of Flora and Nizina the concentration of fructose was two times more than glucose. Differences in the content wine, malic, lemon and succinic acids in berries varieties of Flora and Nizina were insignificant. In the berries of Anyuta variety, the concentration of lemon and succinic acids was more, malic was less than other varieties. Most of the studied varieties of berries contain malic and wine acids. More of cations of potassium, sodium, calcium and magnesium then in other varieties and it contain less than Anyuta berries. The difference in the content of various cations in the berries of varieties of Flora and Nizina is negligible. Tasting score of fresh grape of Flora variety was 7.0, Nisina - 7.8 and Aniyta - 7.6 points

DescriptionIn practical use of methods of applied statistics we do not apply separate methods for describing data, estimation, testing hypotheses, but we must use deployed whole procedures - the so-called "statistical technology". The concept of "statistical technology" is similar to the concept of "technological process" in the theory and practice of organization of production. It is quite natural that some statistical technology can better meet the needs of the researcher (user, statistics) than others, some - are modern, and others - outdated, some properties are studied, and the others - no. It is important to stress that a qualified and efficient use of statistical methods - this is not one single statistical hypothesis testing and estimation of characteristics or parameters of a given distribution from fixed family. This kind of operations - only the individual building blocks that make up the statistical technology. The procedure of the statistical data analysis - is an information process, in other words, one or other information technology. Statistical information is subject to a variety of operations (series, parallel, or more complex schemes). In this article we discuss statistical technologies and the problem of "docking" algorithms. We introduce the concept of "high statistical technologies" and then we prove the necessity of their development and application. As the examples we have given the researches of Institute of high statistical technologies and econometrics of Bauman Moscow State Technical University. We have also considered a number of education problems in domain of high statistical technologies
