Universities of the North-western federal district in Russian-Finnish research cooperation

This article focuses on the cooperation between universities of the North-western federal district (NWFD) of the Russian Federation, Sweden, and Finland, its intensity and territorial differentiation. The analysis was conducted on the basis of public domain information on the international activity of universities available on their official websites. The authors identify the principle areas and leading centres of such cooperation. The NWFD universities have significant experience in cooperation with Finnish universities. Cooperation with Swedish universities is proved to be less developed. Approximately 50 NFWD universities, 29 of which are located in Saint Petersburg, are involved in cooperation; most NWFD universities do not cooperate with the mentioned countries. Such low degree of cooperation in the field of education is a serious inhibiting factor, which reduces competitiveness on the modern market of educational services

International research cooperation in the Baltic region: a scientometric analysis

This article examines the processes of international research cooperation in the Baltic Sea region. It focuses on research works published in the leading periodicals in 1993-2012. The empirical material is collected from the world’s largest abstract and citation database, SciVerse Scopus, which makes it possible to evaluate macroindicators at the national and global levels as well as the contribution of scholars to the global progress. The article also offers an assessment of the efficiency of research activities in the Baltic Sea region countries. It is based on a number of scientometric indicators that reflect the performance of universities in terms of research journal publications and the development of research cooperation in the field of Baltic studies. The authors consider the dynamics of research contribution and academic cooperation in the Baltic Sea countries in four leading fields - i. e. agricultural and biological sciences, Earth sciences, ecology and social sciences presented in the SciVerse Scopus scientometric database. The article provides a map of research cooperation in the Baltic Sea region

Features of geological structure and formation of oil & gas deposits in the Vuktyl thrust fault region

The paper is devoted to modeling of the processes of oil and gas deposits formation of the Vuktyl thrust development area, to which the largest in the Timan-Pechora oil and gas province is associated with the same oil and gas condensate deposit. Oil and gas of deeply buried formations of the autochthon of the overthrust region remains poorly studied. Therefore, application of modern methods of basin modeling is relevant for oil and gas content estimation. In order to simulate the section, Schlumberger PetroMod software package was used. The package allows to determine the history of generation of hydrocarbons on the geological time scale, migration paths, amount and type of oil and gas accumulations in both surface and reservoir conditions. Using the 1D and 2D modeling of the Vuktylskaya-58 parametric well and the overthrust region models were obtained. The models reflect the modern geological section, its evolution during the geological time. The processes of formation of oil and gas were studied. As a result, it was shown that the parent rocks of the allochthonous section part could not participate in the formation of the main gas-condensate deposit of the Vuktyl deposit because they entered only the main oil formation zone. In deeply buried deposits of the autochthon starting from the Permian and Triassic formation of the Vuktylsky gas-condensate field and possibly the deposits in poorly studied deep formations could be caused by processes of generation of gases and gas condensates. That is proved by the discovery of a large number of gas emergences beyond the 4-5 km in a section of the only well drilled beyond the 6 km such as Vuktylskaya-58. Generation and accumulation of gas hydrocarbons occurred mainly after the appearance of thrust dislocations, when the main traps were formed both at ordinary and high depths

Copolymer of chitosan with acrylamide: electron beam stimulated synthesis, structure and properties

The aim of this research was to obtain the grafted copolymer of chitosan with acrylamide using the electron beam irradiation. Radiation dose was varied from 6 to 160 kGy. The highest yield of the product was observed at radiation dose of 12–40 kGy. Further increase in the dose caused a decrease in the product yield as well as its solubility in water. Using gel permeation chromatography, it was confirmed that unreacted chitosan remained in the product. NMR study of the water-soluble part of the product obtained under the doses of 6, 12, and 20 kGy showed that the length of the side chains of grafted acrylamide was about 2 elementary units. Investigation of chitosan solutions by means of dynamic light scattering revealed the presence of chitosan agglomerates in the solution. The possibility of obtaining dense films was demonstrated. Mechanical treatment of the copolymer in the ball mill caused an increase in the solubility of the samples obtained even at radiation doses of 80 and 160 kGy. It was determined by means of chromatographic methods that there were no products with low molecular weight in the ball-milled product, and unreacted chitosan did not undergo mechanocracking during the mechanical treatment

Defect and structural imperfection effects on the electronic properties of BiTeI surfaces

Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.-- et al.The surface electronic structure of the narrow-gap seminconductor BiTeI exhibits a large Rashba-splitting which strongly depends on the surface termination. Here we report on a detailed investigation of the surface morphology and electronic properties of cleaved BiTeI single crystals by scanning tunneling microscopy, photoelectron spectroscopy (ARPES, XPS), electron diffraction (SPA-LEED) and density functional theory calculations. Our measurements confirm a previously reported coexistence of Te- and I-terminated surface areas originating from bulk stacking faults and find a characteristic length scale of ∼100 nm for these areas. We show that the two terminations exhibit distinct types of atomic defects in the surface and subsurface layers. For electronic states resided on the I terminations we observe an energy shift depending on the time after cleavage. This aging effect is successfully mimicked by depositon of Cs adatoms found to accumulate on top of the I terminations. As shown theoretically on a microscopic scale, this preferential adsorbing behaviour results from considerably different energetics and surface diffusion lengths at the two terminations. Our investigations provide insight into the importance of structural imperfections as well as intrinsic and extrinsic defects on the electronic properties of BiTeI surfaces and their temporal stability.This work was financially supported by the Deutsche Forschungsgemeinschaft through FOR1162 and the Bundesministerium für Bildung und Forschung (grant numbers 05K10WW1/2 and 05KS1WMB/1).
