TO THE QUESTION OF PHENOLOGY OF СONVALLARIA MAJALIS L. IN THE CONDITIONS OF THE MIDDLE DON
DescriptionFor the conservation of biodiversity, this study of patterns of biological processes and phases in the development of Convallaria majalis L. that are repeated annually becomes actual. In the article, we have presented an analysis of five years of observations of the rhythm of the development of Convallaria majalis L. in the conditions of the middle Don. There were allocated phenological phases of lily of the valley: vegetative (beginning of sprout growth, deploying of leaves), bud formation, flowering (disclosure of the first flower, mass blossoming, the withering of separate flowers, the ending of flowering), fruitage (the beginning of fruit setting, mass of fruit setting, mass ripening of fruits), the end of the vegetation (appearance of the first changes in color of leaves, the complete drying). We have defined daily average temperature and the appropriate amount of positive temperatures for the passage of various phases of development Convallaria majalis L. By the results of two growing seasons, the optimal daily average temperature for the flowering period is 14,3 ° C (the sum of average daily temperatures 161,3-204, 0С) - until 9-15 days. At higher daily air temperatures flowering begins at lower amount of positive and effective temperatures after 40-45 days after the start of the vegetation. At lower daily air temperatures flowering is longer than at higher. In the conditions of the middle Don there were allocated some examples of Convallaria majalis L. which bloom two years in a row

COGNITIVE MODELS OF PREDICTION THE DEVELOPMENT OF A DIVERSIFIED CORPORATION
DescriptionThe application of classical forecasting methods applied to a diversified corporation faces some certain difficulties, due to its economic nature. Unlike other businesses, diversified corporations are characterized by multidimensional arrays of data with a high degree of distortion and fragmentation of information due to the cumulative effect of the incompleteness and distortion of accounting information from the enterprises in it. Under these conditions, the applied methods and tools must have high resolution and work effectively with large databases with incomplete information, ensure the correct common comparable quantitative processing of the heterogeneous nature of the factors measured in different units. It is therefore necessary to select or develop some methods that can work with complex poorly formalized tasks. This fact substantiates the relevance of the problem of developing models, methods and tools for solving the problem of forecasting the development of diversified corporations. This is the subject of this work, which makes it relevant. The work aims to: 1) analyze the forecasting methods to justify the choice of system-cognitive analysis as one of the effective methods for the prediction of semi-structured tasks; 2) to adapt and develop the method of systemic-cognitive analysis for forecasting of dynamics of development of the corporation subject to the scenario approach; 3) to develop predictive model scenarios of changes in basic economic indicators of development of the corporation and to assess their credibility; 4) determine the analytical form of the dependence between past and future scenarios of various economic indicators; 5) develop analytical models weighing predictable scenarios, taking into account all prediction results with positive levels of similarity, to increase the level of reliability of forecasts; 6) to develop a calculation procedure to assess the strength of influence on the corporation (sensitivity) of its member enterprises; 7) to finalize the software tools the ask analysis to the level of information technology, given its adaptation and development to predict actions in a diversified corporation

MODELING DEEP BAR INDUCTION MOTORS FOR SUGAR FACTORY ELECTRICAL POWER SUPPLY SYSTEMS
DescriptionThe article is devoted to solving the urgent task, which is improving the accuracy of transient simulation modes of power supply systems of sugar factories. The material of the article is exploratory in nature, manifested in the fact that we have studied various mathematical models designed for the analysis of symmetric modes of deep bar induction motors. A number of the provisions of article have scientific novelty, which lies in the approach to the choice of the coordinate system for modeling deep bar induction motors. We have formulated the requirements for transient analysis method for deep bar induction motor. We have developed the mathematical models of high-voltage induction motors in different coordinate systems for the analysis of steady-state and transient modes of operation. Based on double-circuit rotor model of induction motor, an analytical expression for the frequency characteristic of the deep bar induction motor is obtained. As an example, we have calculated and presented real and imaginary parts of the frequency characteristic of the induction motor type 2АЗМ-2000 with slip s = 1. The mathematical models of induction motors allow using mathematical apparatus more efficiently to explore different symmetrical modes of engines. The study proposed to use transients in the power supply systems of sugar factories for the analysis. The authors suggest an approach to modeling, which can also be useful for modeling induction generators

06.00.00 Agricultural sciences
DescriptionThe article presents the comparative assessment of economic traits of Holstein cows of various ecogenetic types in the Volgograd region, the Russian Federation. The study of adaptive ability of Holstein cattle imported from the United States (245 heads), Denmark (245 heads), Germany (386 heads), and Australia (250 heads) has been carried out based on breeding plant OOO "Donskoye" in Russia since 2006. The milk producing ability of the animals was studied during the period of first three lactations. The cows imported from the United States showed the maximum productivity. The cows from the USA and Germany were registered to have the highest fat content in milk. The mathematical modeling for predicting production processes revealed that with respect to the milk yield, the Holsteins of Danish selection were superior to the cows of American, German, and Australian selections by the fifth lactation. The high correlation between the milk yield and the body weight, as well as between the body weight and the fat content of milk from Holstein cows of various selections has been established. The cows of Danish, German, and Australian selections showed a positive correlation between economic traits and genetic parameters for the period of three lactations. The cows from Australia have been proved to have higher indices of protein composition of milk (the total nitrogen content, the amount of essential amino acids). The level of the adaptive ability of the animals of the same breed but different eco-genetic types has been found to be stable

DescriptionAdequate and effective assessment of the efficiency, effectiveness and the quality of scientific activities of specific scientists and research teams is crucial for any information society and a society based on knowledge. The solution to this problem is the subject of scientometrics and its purpose. The current stage of development scientometrics differs greatly from his previous appearance in the open as well as paid on-line access to huge amount of detailed data on a large number of indicators on individual authors and on scientific organizations and universities. The world has well-known bibliographic databases: Web of Science, Scopus, Astrophysics Data System, PubMed, MathSciNet, zbMATH, Chemical Abstracts, Springer, Agris, or GeoRef. In Russia, it is primarily the Russian scientific citing index (RSCI). RSCI is a national information-analytical system, accumulating more than 9 million publications of Russian scientists, as well as the information about citation of these publications from more than 6,000 Russian journals. There is too much information; it is so-called "Big data". But the problem is how to make sense of these large data, more precisely, to identify the meaning of scientometric indicators) and thus to convert them into great information ("great information"), and then apply this information to achieve the objective of scientometrics, i.e. to transform it into a lot of knowledge ("great knowledge") about the specific scientists and research teams. The solution to this problem is creating a "Scientific smart metering system" based on the use of the automated system-cognitive analysis and its software tools – an intellectual system called "Eidos". The article provides a numerical example of the creation and application of Scientometric intelligent measurement system based on a small amount of real scientific data that are publicly available using free on-line access to the RSCI
