Compact objects in conformal nonlinear electrodynamics

In this paper we consider a special case of vacuum non-linear electrodynamics with a stress-energy tensor conformal to the Maxwell theory. Distinctive features of this model are: the absence of dimensional parameter for non-linearity description and a very simple form of the dominant energy condition, which can be easily verified in an arbitrary pseudo-riemannian space-time with the consequent constrains on the model parameters. In this paper we analyse some properties of astrophysical compact objects coupled to conformal vacuum non-linear electrodynamics

Contribution of nonlinearity in tsunami generated by submarine earthquake

International audienceRapid co-seismic bottom displacements during strong submarine earthquake give rise to intensive low-frequency elastic oscillations of water layer. Nonlinear energy transfer from the elastic oscillations to long gravitational waves may provide an additional contribution to tsunami. The nonlinear tsunami generation mechanism is examined analytically. Finiteness of bottom elasticity is taken into account. General parameters responsible for amplitude and energy of the nonlinear contribution to tsunami wave are revealed

Role of Russia in peaceful settlement of the conflict of North and South Korea: event analysis

This study analyzes the conflict between North Korea and South Korea. The Russian Federation has played an important role in the peaceful settlement of this conflict, which has an impact on the formation of the appearance of Russia in the international arena. The theoretical basis of the study was the theory of images, communication and international conflicts. Using the eventanalysis method, an event-based picture of the conflict was built, comparative assessments were made, conflicting parties, indirect participants and intermediaries were identified. An analysis of the current situation is given, groups of interests and the role of Russia in the peaceful settlement of this conflict are identified.Este estudio analiza el conflicto entre Corea del Norte y Corea del Sur. La Federación de Rusia ha desempeñado un papel importante en la solución pacífica de este conflicto, que tiene un impacto en la formación de la aparición de Rusia en la arena internacional. La base teórica del estudio fue la teoría de las imágenes, la comunicación y los conflictos internacionales. Utilizando el método de análisis de eventos, se construyó una imagen del conflicto basada en eventos, se realizaron evaluaciones comparativas, se identificaron las partes en conflicto, los participantes indirectos y los intermediarios. Se presenta un análisis de la situación actual, se identifican los grupos de intereses y el papel de Rusia en la solución pacífica de este conflicto.Este estudo analisa o conflito entre a Coréia do Norte e a Coréia do Sul.

On a possibility of inelasticity partial coefficient K sub gamma determination in pi C and pi Pb interactions at 10 to the 14th power eV (experiment PAMIR 1)

The investigation of hadron-nuclear interactions in Pamir experiment is carried out by means of X-ray emulsion chambers of two types: carbon (C) and lead (Pb). While comparing the results from the chambers of both types it was found a discrepancy in n sub h and E sub h(1)R values. The observed discrepancy in C and Pb chambers is connected with the difference in values of effective coefficients of energy transfer to the soft component K sub eff for C and Pb chambers

Innovations and support for quality in agriculture : a case study

The aim of the article is to investigate the economic and legal aspects of integrating innovations in agriculture and supporting the quality of agricultural products in the context of modern Russia. Throughout the process of research, the authors analyzed the directions of agricultural sector development, mechanisms of quality and safety support, as well as customer rights protection. As a result the authors have agreed on, the need to integrate cluster models in the agricultural sector, notably in the bee-keeping, seed production (including financing of this activity), as well as legislative stimulus to shift towards «green» biotechnology in the domestic agriculture. Based on the research conducted, the authors have proposed mechanisms to improve the current Russian legislation in the spheres of innovation development and support for quality and safety of agricultural production.peer-reviewe

Socio-Cultural Potential of a scientific Library of Higher Education Institution in Students’ value Attitude to Education Development

© 2015 Canadian Center of Science and Education. All rights reserved. The article is aimed to identify social-cultural potential of a scientific library of higher education institution in students’ value attitude to education development, and also to reveal the content and technology of students’ involvement in its activity. With reference to the specified goals, the main approach to this issue research has been the social-cultural approach that determines the efficiency of applied problems solutions in the process of students’ value attitude to education development in the context of a scientific library of higher education institution. In the article there has been revealed the specifics of social-cultural activity of a scientific library aimed at the formation of students’ value attitude to education; there has been presented the complex of task-oriented and systematic pedagogical impacts on personality consciousness and behavior via involving tem in social-cultural forms of work of a scientific library in the process of which there takes place the development of students’ value attitude to education. Materials of this article can be useful for teachers to develop students’ value attitude not only to education but to scientific-research activity as well; to researchers who deal with the subject of personality value attitude development

Efficiency of carotine-chlorophyllic complexes use in a-hypovitaminosis of poultry

The principal purpose of this study was to investigate the possibility of using chloroprenol as a vitamin supplement in diets of broiler chickens for the prevention of A-vitamin deficiencies and improve the commercial quality of poultry products. In accordance with desired goal we have estimated the clinical-biochemical status of the broiler chickens under production-line conditions, defined the optimal dosages of chloroprenol for the broiler chicken, determined the effect of the drug on the morphological and biochemical parameters of blood, studied their effect on the natural resistance parameters of the body, accumulation of biological active substances in the liver, viability and productivit
