Generation Performance in Selection of Different Flower Types of Sheep

The weight of the offspring is used to compare the degree of manifestation of major selection qualities in the selection of karakul sheep with the indicators acquired in the selection of other species of shee

Torsion free groups with indecomposable holonomy group I

We study the torsion free generalized crystallographic groups with the indecomposable holonomy group which is isomorphic to either a cyclic group of order ${p^s}$ or a direct product of two cyclic groups of order ${p}$.Comment: 22 pages, AMS-Te

Solving the problem of credit defaults in retail sector

The article analyzes dynamics of the volume and annual rate of loan delinquency of the country’s population for intermediate quarter dates, compares default retail credit portfolios with similar portfolio of organizations, and determines the main reasons for appearance of population’s debts before banks. It is concluded that it is necessary for banks to focus on development of their own tools and technologies of payment recovery, related to determination of early problematic debt for the purpose of taking preventive measures for preventing the appearance of past-due debts, which is possible under the condition of investing money assets into own analytical and technological tools. An approach to segmentation of debts and factors that could be used as indicators in the process of accompanying and servicing of credits are offered.peer-reviewe

СРАВНИТЕЛЬНОЕ ИССЛЕДОВАНИЕ ОСОБЕННОСТЕЙ СОЦИАЛЬНОЙ ИДЕНТИЧНОСТИ У РАЗЛИЧНЫХ КАТЕГОРИЙ ОБУЧАЮЩИХСЯ В УСЛОВИЯХ ВЫСШЕГО ОБРАЗОВАНИЯ

This article investigates the characteristics of meaningful social identity of an individual in terms of higher education; reveals its structure and analyzes the functional blocks which are basic, personal and professional one. The research explains that various functional blocks of social identity are activated at different levels and forms of education according to the age characteristics of students. The full-time students demonstrate activating of the basic block; the students of correspondence courses and PhD-students demonstrate activating of professional and personal ones. The author specifies the dominant professional types of the students trained in higher institutions. The research is significant due to applying of the research results in politics, education, business and management. In particular, they can be applied in social and psychological forecasting, development of psychotherapeutic practice, increasing effectiveness of training professionals in new social-economic conditions. The data represented can be applied in the educational process, as they supplement and specify the sections of social, educational and aged psychology.В данной статье исследованы содержательные характеристики социальной идентичности личности в условиях высшего образования, выявлена ее структура, проведен анализ функциональных блоков: базового, личностного и профессионального. В результате сравнительного исследования доказано, что на разных уровнях и формах обучения активизируются различные функциональные блоки социальной идентичности в зависимости от возрастных особенностей, а именно: у студентов очной формы обучения - базисный; у студентов заочной формы обучения и аспирантов - профессиональный и личностный. А также экспериментально определены доминирующие профессиональные типы у разных категорий обучающихся в вузе. Практическая значимость исследования определяется тем, что его результаты могут найти применение в политике, образовании, бизнесе, управлении. В частности, могут быть полезны для построения социально-психологических прогнозов, развития психотерапевтической практики, повышения эффективности подготовки специалистов для работы в новых социально-экономических условиях. Данные могут использоваться в учебном процессе, так как дополняют и детализируют разделы социальной, педагогической и возрастной психологии

Anisotropic flow fluctuations in hydro-inspired freeze-out model for relativistic heavy ion collisions

The LHC data on event-by-event harmonic flow coefficients measured in PbPb collisions at center-of-mass energy 2.76 TeV per nucleon pair are analyzed and interpreted within the HYDJET++ model. To compare the model results with the experimental data the unfolding procedure is employed. The essentially dynamical origin of the flow fluctuations in hydro-inspired freeze-out approach has been established. It is shown that the simple modification of the model via introducing the distribution over spatial anisotropy parameters permits HYDJET++ to reproduce both elliptic and triangular flow fluctuations and related to it eccentricity fluctuations of the initial state at the LHC energy.Comment: 12 pages including 9 figures as EPS-files; prepared using LaTeX package for publication in the European Physical Journal

THE ASSESSMENT OF CLIMATE CHANGE AND WATERSHED EFFECT ON THE HETEROTROPHIC METABOLISM IN THE LAKE ONEGO ECOSYSTEM

Lake Onego, as one of the largest water bodies in a humid zone, is the recipient of terrestrial carbon and plays an important role in the global balance of this element. Due to heterotrophic metabolism in the Lake Onego ecosystem, substantial emissions of carbon dioxide from this lake into the atmosphere can be assumed. However, the extent of this phenomenon is still poorly known. As a climate change has led to an increase in water and organic matter flow into the northern water bodies, the carbon balance study of aquatic ecosystems is of particular relevance. The elements of the water balance for the Lake Onego catchment area in the current climate conditions are assessed. Based on satellite images the model of Lake Onego watershed terrestrial ecosystems is used to simulate the flow of organic matter into the lake with different types of vegetation and topography consideration. The assessment of the benthic communities habitat is carried out taking into account the accumulation of organic matter in various parts of Lake Onego

Cyclic peroxides and related initiating systems for radical polymerization of methyl methacrylate

Cyclic peroxides as initiators for the radical polymerization of methyl methacrylate were proposed. The initial rates, initiation rates, and effective activation energies of polymerization initiated by cyclic peroxides and cyclic peroxide-1-pyridyl-2-ferrocene systems were determined. The radical yields to the volume upon the thermal decomposition of cyclic peroxides and their catalytic decomposition in the presence of 1-pyridyl-2-ferrocene were determined. In combination with 1-pyridyl-2-ferrocene cyclic peroxides form efficient initiating systems favoring an increase in the polymerization rate, a decrease in the molecular weights, and an increase in syndiotacticity of the synthesized poly(methyl methacrylate). © 2013 Springer Science+Business Media New York
