The relativistic impulse approximation for the exclusive electrodisintegration of the deuteron

The electrodisintegration of the deuteron in the frame of the Bethe-Salpeter approach with a separable kernel of the nucleon-nucleon interaction is considered. This conception keeps the covariance of a description of the process. A comparison of relativistic and nonrelativistic calculations is presented. The factorization of the cross section of the reaction in the impulse approximation is obtained by analytical calculations. It is shown that the photon-neutron interaction plays an important role.Comment: 31 pages, 14 figures, 1 tabl

Residents’ interest to form a “green” territory brand

The main aim of this article is to examine the residents’ interest of a region to form a territorial “green” brand. It refers to the region of Rostov where there is a continuous attempt to develop the territory based on sustainable green initiatives. The article reveals if the residents are aware on the authorities’ efforts and how the population supports the initiatives as well as how active the residents are to develop the territory. The results of this research allow to forecast the success of the “green” brand formation with certain correction of the priorities concerning the informational and communication work to explain the significance of the given process to the residents and possibly the improvement of the population’s standard of living.peer-reviewe

Magnetothemopower study of quasi two-dimensional organic conductor α\alpha-(BEDT-TTF)2_2KHg(SCN)4_4

We have used a low-frequency magneto-thermopower (MTEP) method to probe the high magnetic field ground state behavior of $\alpha$-(BEDT-TTF)$_2$KHg(SCN)$_4$ along all three principal crystallographic axes at low temperatures. The thermopower tensor coefficients ($S_{xx}, S_{yx}$ and $S_{zz}$) have been measured to 30 T, beyond the anomalous low temperature, field-induced transition at 22.5 T. We find a significant anisotropy in the MTEP signal, and also observe large quantum oscillations associated with the de Haas - van Alphen effect. The anisotropy indicates that the ground state properties are clearly driven by mechanisms that occur along specific directions for the in-plane electronic structure. Both transverse and longitudinal magnetothermopower show asymptotic behavior in field, which can be explained in terms of magnetic breakdown of compensated closed orbits.Comment: 9 pages, 10 figure

Partial level density of the n-quasiparticle excitations in the nuclei of the 39< A <201 region

Level density and radiative strength functions are obtained from the analysis of two-step cascades intensities following the thermal neutrons capture. The data on level density are approximated by the sum of the partial level densities corresponding to n quasiparticles excitation. The most probable values of the collective enhancement factor of the level density are found together with the thresholds of the next Cooper nucleons pair breaking. These data allow one to calculate the level density of practically any nucleus in given spin window in the framework of model concepts, taking into account all known nuclear excitation types. The presence of an approximation results discrepancy with theoretical statements specifies the necessity of rather essentially developing the level density models. It also indicates the possibilities to obtain the essentially new information on nucleon correlation functions of the excited nucleus from the experiment.Comment: 29 pages, 8 figures, 2 table

Improving the efficiency of university management : teacher’s performance monitoring as a tool to promote the quality of education

This study aims to examine the essence of education monitoring, its place in the higher education management system and the practical implementation of teacher’s performance monitoring as a tool to promote the quality of education. The article considers theoretical aspects of monitoring as a tool to promote the quality of education, assesses the performance of the university departments, research and teaching staff and discusses the results and suggestions on how to improve monitoring activities in higher education. Based on their research and findings, the authors claimed that the monitoring of the performance of the university research and teaching staff on the base of an indicator system in terms of education, methodology, research, organization and counselling services would lead to valid conclusions as to the effective performance of both individual researchers and teachers and university departments, in general.peer-reviewe

Regge Field Theory in zero transverse dimensions: loops versus "net" diagrams

Toy models of interacting Pomerons with triple and quaternary Pomeron vertices in zero transverse dimension are investigated. Numerical solutions for eigenvalues and eigenfunctions of the corresponding Hamiltonians are obtained, providing the quantum solution for the scattering amplitude in both models. The equations of motion for the Lagrangians of the theories are also considered and the classical solutions of the equations are found. Full two-point Green functions ("effective" Pomeron propagator) and amplitude of diffractive dissociation process are calculated in the framework of RFT-0 approach. The importance of the loops contribution in the amplitude at different values of the model parameters is discussed as well as the difference between the models with and without quaternary Pomeron vertex.Comment: 34 pages, 36 figure

An efficient strategy for the development of tourism at regional level

Tourism promotes the development of small and medium-sized business, an increase in employment and self-employment, and allows smoothing the disproportions of territorial development. The objective of this work is to study the modern state of the tourism industry and to reveal the strategical development trends of tourism in the regions of the Southern Federal District (SFD). The statistical data of Rosstat (Federal Service of State Statistics), Federal Agency for Tourism, the database of the EMISS (Unified Interdepartmental Statistical Information System) and other open sources of information were used as the sources of secondary information. The practical part of the research is based upon the application of the author’s method of estimation of the current state of the tourism industry in the regions that presupposes the calculation of the complex index of tourism development in the region. The results of the performed research allowed classifying the regions according to the level of tourism development and determining the strategies of competitiveness improvement of the regional touristic products on its base.peer-reviewe

Investment instruments to stimulate depressed regions’ development

There are a number of problems of regional development, including tgose that impress most of all – the growing differentiation and polarization of the regions’ development. It caused the emergence of so called depressed territories with the level of social and economic development being the lowest among the territories of this type. In this context, it is quite urgent to stimulate the development of depressed territories, in particular, the development and efficient use of investment instruments in this process. This research aims at stipulating investment instruments to support the development of depressed regions. The article considers theoretical grounds of the emergence and functioning of depressed regions, foreign experience on financial support for the depressed territories’ development. Based on experts’ survey, investment instruments to support the development of depressed regions are stipulated, peculiarities of forming priorities of developing depressed regions are specified, an algorithm for selecting top priority areas for economic activity in the depressed region is offered, a generalized system of financial instruments to stimulate the development of priorities for sustainable development of the depressed region is given, and consequences of applying them in the region are characterized.peer-reviewe

Effect of electron irradiation on vortex dynamics in YBa_2Cu_3O_{7-x} single crystals

We report on drastic change of vortex dynamics with increase of quenched disorder: for rather weak disorder we found a single vortex creep regime, which we attribute to a Bragg-glass phase, while for enhanced disorder we found an increase of both the depinning current and activation energy with magnetic field, which we attribute to entangled vortex phase. We also found that introduction of additional defects always increases the depinning current, but it increases activation energy only for elastic vortex creep, while it decreases activation energy for plastic vortex creep.Comment: 4 pages, 3 figures, submited to Phys.
