Electron tunneling to the surface states at photocatalysis

Simulation of tunneling electrons excited by the sunlight in TiO2 to surface states is performed for TiO2/Si nanostructure. The tunneling transmission coefficient of the surface states created by organic compounds was calculated by phase function method. Dependence of the transmission coefficient of tunneling electrons on potential barrier parameters is explained by interference of transmitted and reflected waves

Problems of modern higher education in the sphere of Russian philology and the ways of solving them (On the example of the situation in Kazan federal university)

© Author(s).The article is devoted to the actual problems of modern higher education in the sphere of Russian Philology which depends on the world crisis situation, that continues to persist, despite the efforts to reform it. This article aims to mark some important problematical items necessary to realize the reformation of higher philological education and to formulate a number of key statements that could help in future. The theoretical character of the article is based on analytical approach to the problems of higher education. The article analyzes modern curricula on “Philology” and “Pedagogical education”, the bases for professional training at the undergraduate and graduate programs in Kazan Federal University. The practical significance of the article lies in the possibility of using the results of the study to improve a curriculum in training future specialists not only in Russia

Features of French, American and Russian intercultural interaction

The article deals with the functioning of cultural stereotypes in French, American and Russian linguistic consciousness. Cross-cultural interaction is interpreted within the framework of mastering linguocultural communication codes and the worldview of allophones. The analysis of factual data is based on the linguosemiotic approach to its interpretation within a discursive utterance

Emotive-expressive potential of phraseology of linguistic identity: Vladimir Putin

Deals with the linguistic identity of the politician on the material of statements of V.V. Putin. The politician's discourse is studied based on the interpretative analysis of phraseolog

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

Radiological diagnosis of copd exacerbations

Review of the literature in problems of diagnosis of chronic obstructive pulmonary disease (COPD) exacerbation and the main radiological techniques of COPD exacerbation were presented. Diagnostic possibilities of screen-film radiography, functional low-dose digital fluorography (LDDR), high-resolution computed tomography (HRCT), inspiration-expiration HRCT, ventilation-perfusion pulmoscintigraphy and magnetic resonance tomography in patients with COPD exacerbation were described. The advantages offunctional LDDR in patients with COPD exacerbation were shown

Temperature dynamics of organic matter of the bazhenov suite from electron paramagnetic resonance

© SGEM2017. All Rights Reserved. Revealing the conditions and mechanisms of evolution of oil deposit based on optical and electron microscopy, electron paramagnetic resonance (EPR) is a necessary step to create improved of recovery methods. Application EPR for study temperature, mechanical and radiation dynamics of organic matters were presented in this communication. The subject of the investigation was the core material from Bazhenov suite (East Siberian oil and gas province). In order to reveal the features of the material composition and the generation potential of the organic matter of rocks, the EPR spectra of the Bazhenov suite samples were investigated. Methods of chloroform extraction, isothermal treatment at a temperature of 350°C and 600°C in hydrogen atmosphere for samples from core section were used. The main hydrocarbon generation zone was established during the degradation of kerogen at 350°C. The inhomogeneity of distribution of carbonate matter is revealed. The main phase of oil generation in the area of 350°С is accompanied by the destruction of kerogen and the formation of a liquid phase of hydrocarbons and leaching of iron. Potential hydrocarbon generation opportunities are associated with destruction of kerogen at 350°C

COMPLEX ESTIMATION OF BRONCHOPULMONARY SYSTEM IN PATIENTS WITH HODGKINS LYMPHOMA

One of the important problems with patients with Hodgkin's lymphoma is lung injury, caused both by a tumor effect and the influence of chemoradiotherapy. Before the treatment an obstructive lung function pattern connected with tumor substrate has been revealed in 38% of cases. After chemoradiotherapy the restrictive lung pattern was shown in 14% of the patients and mixed lung pattern was seen in 12% of the cases, which were caused by the development of pneumosclerosis and emphysema
