Regional manifestations of changes in atmospheric circulation in the Central Black Earth region : by the example of Belgorod region

The aim of this work is the estimation of the reasons of occurrence of the area of dangerous hydrometeorological phenomena and the analysis of the circulation processes, leading to the establishment of extreme weather conditions in the region. Using the calendar of the consistent changes of elementary circulation mechanisms and daily observations of the weather in the south of Central Black Earth region (by the example of Belgorod region).yesBelgorod State National Research Universit

Reconstruction of Zigzag Graphene Edges: Energetics, Kinetics and Residual Defects

Ab initio calculations are performed to study consecutive reconstruction of a zigzag graphene edge. According to the obtained energy profile along the reaction pathway, the first reconstruction step, formation of the first pentagon-heptagon pair, is the slowest one, while the growth of an already nucleated reconstructed edge domain should occur steadily at a much higher rate. Domains merge into one only in 1/4 of cases when they get in contact, while in the rest of the cases, residual defects are left. Structure, energy and magnetic properties of these defects are studied. It is found that spontaneous formation of pairs of residual defects (i.e. spontaneous domain nucleation) in the fully reconstructed edge is unlikely at temperatures below 1000 K. Using a kinetic model, we show that the average domain length is of several $\mathrm{\mu}$m at room temperature and it decreases exponentially upon increasing the temperature at which the reconstruction takes place.Comment: 5 pages, 4 figure

Electromagnetic response of the three-layer construction on the basis of barium hexaferrite and a foam glass

This paper contains results of study of the frequency dependence of reflection coefficient of the ceramic surface coated with the construction consisting of following layers: metal, composite on the basis of ferrite with hexagonal structure, and foam glass. It is shown that foam glass layer reduces significantly the reflecting characteristics of the construction

Дискурс коммунизма и социалистическая языковая личность: риторический аспект

Within the conception of the Sochi Linguistic & Rhetorical School the paper argues for the idea of discourse of Communism as a cover term for the «officialese» in the Soviet Union and former Socialist countries singling out four periods of its development: origin, formation, official existence, dismantling. The article pays special attention to the heterogeneity of the longest period of the discourse's official existence, which consists of the alternating stages: rise in the revolutionary and post-revolutionary years, during war and past-war time with the expansion of the discourse of Communism to other countries; and fall with the massive reprisals of 1930s and the “stagnation” epoch. During the period of its official existence three of its facets – official, public and real – reflect contradictions between the Communist ideas imposed by the authorities and the state of the Socialist linguistic personality confronting the meanness of daily life. The paper reveals those contrasts drawing on the diaries of Olga Berggolts and Alexander Dovzhenko as well as the destinies of Mikhail Prishvin, Alexey Tolstoy and Alexander Fadeyev.Dentro de la concepción de la Escuela Lingüística y Retórica de Sochi, el artículo argumenta a favor de la idea del discurso del comunismo como un término de cobertura para los «officialese» en la Unión Soviética y los ex países socialistas que señalan cuatro períodos de su desarrollo: origen, formación, oficial existencia, desmantelamiento. El artículo presta especial atención a la heterogeneidad del período más largo de la existencia oficial del discurso, que consiste en las etapas alternas: ascenso en los años revolucionario y posrevolucionario, durante la guerra y el tiempo de la guerra pasada con la expansión del discurso del comunismo. a otros países; y caer con las represalias masivas de 1930 y la época de "estancamiento". Durante el período de su existencia oficial, tres de sus facetas, oficial, pública y real, reflejan contradicciones entre las ideas comunistas impuestas por las autoridades y el estado de la personalidad lingüística socialista que confronta la mezquindad de la vida cotidiana. El documento revela esos contrastes basados ​​en los diarios de Olga Berggolts y Alexander Dovzhenko, así como los destinos de Mikhail Prishvin, Alexey Tolstoy y Alexander Fadeyev.В русле концепции Сочинской лингвориторической школы статья обосновывает идею дискурса коммунизма, обобщающую интерпретации «официолекта» в Советском Союзе и в бывших странах социализма, и выделяет четыре периода его развития: зарождение, формирование, расцвет и угасание. Отмечена неоднородность наиболее длительного и значимого периода расцвета, который состоит из чередующихся этапов: вознесения в революционные и послереволюционные годы, в военное и послевоенное время, сопровождавшееся расширением границ дискурса коммунизма на другие страны; и упадка, с которым соотносятся массовые репрессии конца 30-х годов и эпоха «застоя». На всех этапах расцвета дискурса коммунизма его три ипостаси – официальная, публичная и реальная – отражали противоречие между коммунистическими идеями, навязываемыми властями, и состоянием социалистической языковой личности, сталкивающейся с превратностями повседневной реальности. Указанные контрасты раскрываются в статье на материале дневников Ольги Берггольц и Александра Довженко, а также на примере литературных судеб Михаила Пришвина, Алексея Толстого и Александра Фадеева

Use Of Plants To Remediate Soil Polluted With Oil

In the present investigation the growing and development ability of various annual and perennial plants to grow on model peat substrate artificially polluted with oil products in the range of concentrations from 1 to 5% was evaluated. The highest tolerance towards peat contamination by oil products has been demonstrated by three annual crops (maize, oat and lupine). These plants were tested for phytoremediation of polluted black soil from the area of oil refinery plant (Mazeikiai, Lithuania), which was treated by association of oil oxidizing bacteria up to residual concentration of the oil products of 4.5 %. The maize plants revealed the highest remediation ability: oil content in the soil decreased by ~ 1.5 times in one month plant vegetation
