Ways to Improve the Management of the Regional Construction Complex

Construction is one of the leading sectors of the economy of Uzbekistan. One of the features of the construction industry is the regional difference in the development of this industry. The goals of the management system of the regional building complex are determined by the characteristics and level of socio-economic development of the region. This article is devoted to the problem of improving the efficiency of the management system of the construction complex of the Samarkand region. It discusses the principles of improving the management relations of the subjects of the construction complex

New records to the flora of Uzbekistan (Middle Asia)

The Republic of Uzbekistan is a Central Asian country with rich native flora. The territory belongs to the Irano-Turanian region in the Ancient Mediterranean floristic subkingdom of Holarctic. The flora of Uzbekistan accounts over 4300 species of vascular plants including large numbers of endemic species, but the check-list is still incomplete. Presented here ten new records to the flora of Uzbekistan, were found during the field studies and examination of herbarium collections preserved at TASH

Features of selecting and structuring Foreign Language Teaching content in Terms of International Component

© 2015 Canadian Center of Science and Education. All rights reserved. Analysis of Russian curricula and textbooks for foreign language demonstrates that most of them don’t meet the requirements of education internationalization. So, the purpose of this paper is to reveal the features of foreign language teaching content selection and structuring based on the international component. The paper reveals the features of foreign language teaching content for students in the context of education internationalization which includes acquisition of knowledge that interprets the main humanity values, touches upon global problems of the modern multicultural world, cross-cultural and socio-cultural knowledge; shaping skills needed for cross-cultural communication, skills to carry out cross-cultural analysis of the interaction ways with the world around as well as formation of transcultural experience. The materials of this paper may be useful for faculty members of vocational training institutions when selecting and structuring the language teaching content as well as for further education courses of foreign language teachers

Impact of Space Weather on Climate and Habitability of Terrestrial Type Exoplanets

The current progress in the detection of terrestrial type exoplanets has opened a new avenue in the characterization of exoplanetary atmospheres and in the search for biosignatures of life with the upcoming ground-based and space missions. To specify the conditions favorable for the origin, development and sustainment of life as we know it in other worlds, we need to understand the nature of astrospheric, atmospheric and surface environments of exoplanets in habitable zones around G-K-M dwarfs including our young Sun. Global environment is formed by propagated disturbances from the planet-hosting stars in the form of stellar flares, coronal mass ejections, energetic particles, and winds collectively known as astrospheric space weather. Its characterization will help in understanding how an exoplanetary ecosystem interacts with its host star, as well as in the specification of the physical, chemical and biochemical conditions that can create favorable and/or detrimental conditions for planetary climate and habitability along with evolution of planetary internal dynamics over geological timescales. A key linkage of (astro) physical, chemical, and geological processes can only be understood in the framework of interdisciplinary studies with the incorporation of progress in heliophysics, astrophysics, planetary and Earth sciences. The assessment of the impacts of host stars on the climate and habitability of terrestrial (exo)planets will significantly expand the current definition of the habitable zone to the biogenic zone and provide new observational strategies for searching for signatures of life. The major goal of this paper is to describe and discuss the current status and recent progress in this interdisciplinary field and to provide a new roadmap for the future development of the emerging field of exoplanetary science and astrobiology.Comment: 206 pages, 24 figures, 1 table; Review paper.

A self-consistent determination of the temperature profile and the magnetic field geometry in winds of late-type stars

Cool giant and supergiant stars generally present low velocity winds with high mass loss rates. Several models have been proposed to explain the acceleration process of these winds. Although dust is known to be present in these objects, the radiation pressure on these particles is uneffective in reproducing the observed physical parameters of the wind. The most promising acceleration mechanism cited in the literature is the transference of momentum and energy from Alfven waves to the gas. Usually, these models consider the wind to be isothermal. We present a stellar wind model in which the Alfven waves are used as the main acceleration mechanism, and determine the temperature profile by solving the energy equation taking into account both the radiative losses and the wave heating. We also determine self-consistently the magnetic field geometry as the result of the competition between the magnetic field and the thermal pressures gradient. As main result, we show that the magnetic geometry present a super-radial index in the region where the gas pressure is increasing. However, this super-radial index is greater than that observed for the solar corona.Comment: Accepted for publication in Space Science Reviews.
