Conflicting patterns of thought in the Russian debate on transition: 2003-2007
No full textThis article is a continuation of two essays by the same author on Soviet/Russian economic debates between 1987 and 2002 published in Europe-Asia Studies in 2006 and 2007, so now the series of articles covers 20 years of Soviet/Russian discussions on economic reforms. Should Russia strive to become a 'Western' country marked by democracy and a market economy serving the individual interests of its citizens, or was it more important to become a great power again? Are Western patterns of political and economic life suitable for Russia or is the attempt to import foreign institutional structures doomed for failure, making it necessary for Russia to find her own way? This type of question, going far beyond the realm of economics, was and still is at the heart of the debate among Russian economists, which shall be discussed here, on the basis of a qualitative content analysis of the most important economic journals and selected monographs. --

Calculating the radiation flux from the vapour-gas channel in danger-shaped penetration with the electron beam
No full textSince it is not possible to measure directly the depth of the channel which determines the depth of penetration in the process of electron beam welding (EBW), it is necessary to find methods of predicting this parameter on the basis of theoretical models examining the conditions of the energy balance of the channel. The energy balance of the beam is determined by the shape of the surface of the channel. The main radiation losses result from the reflected electrodes, evaporation and thermal radiation. Thus, evolution of the heat flow, emitted from the channel, is of obvious theoretical and practical interestTranslated from Russian (Fiz. Khim. Obrab.

Indication of the condition of woody plants of parks in Dnipropetrovsk on morpho-physiological indexes
No full textThe condition of woody plants of parks in the city of Dnipropetrovsk on morpho-physiological index of model trees was investigated. The highest values on the V.A. Alekseev vitality index were recorded for plants in Gagarin Park and Sevastopolskiy Park, the lowest values for Kalinin Park and Мolodezhnyj Park. The lowest values for length and thickness of annual sprouting relative to the control (Petrikovka Park) were found in Kalinin, Globa and Molodezhnyj parks for all studied species of trees, the smallest difference from the control group of plants being found for Robinia pseudoacacia L. There was a lower quantity of leaves on the annual sprouting in plants in Globa, Kalinin and Мolodezhnyj parks. In other parks, the difference between the experiment and the control was not statistically significant. The area of leaves in the trees was lower in the city parks compared with those of the park in the village, with the exception of Gagarin Park. More important, relative to the above-mentioned parameters, were differences in the assimilation area of the annual sprouting, with the exception of Gagarin Park. The amount of chlorophyll a + b in leaves of woody plants of different parks of the city less than in control. The greatest differences of pigment concentration in the leaves of Acer platanoides L. and Tilia plathyphyllos Scop. were found in Kalinin Park. For the leaves of the R. pseudoacacia no significant differences were found between the content of the amount of chlorophyll a + b in the trees which grow in Gagarin, Khmelnitsky and Sevastopolskiy parks and the background values for this parameter. It was found that the amount of chlorophyll a + b in the leaves of T. plathyphyllos and R. pseudoacacia by weight of the leaves on the annual sprouting was lower in the city parks compared with the trees in the village park, with the exception of Gagarin Park. For A. platanoides this difference was found to be significant in all experimental sites. It is appropriate to use such parameters as the length of the annual sprouting as a bioindicator of the environment annual sprouting, the leaf area, the content of chlorophyll a + b based on the weight of the leaves annual sprouting and assimilation area. As test-objects species sensitive to anthropogenic pollution, such as T. plathyphyllos and A. platanoides should be used. The trees in the best condition of vitality (according to the whole complex of indicators) are those in Gagarin, Shevchenko and Sevastopolskiy parks, the worst are in Kalinin, Globa and Мolodezhnyj parks
Tau-p mapping and interpretation of seismic reflection data from the western Isles region of Scotland
No full textSeismic data are conventionally recorded, processed and displayed in the X-T domain, where X is the source-receiver. offset and T is the two-way traveltime. There are advantages, however, in mapping the same data in a different domain; that of intercept time T and horizontal ray parameter p. Computer programs .written for performing the transformation from X-T to -p were adapted for use with marine data acquired in the western Isles region of Scotland in order to obtain information about the velocity structure in that area. The results obtained are compared with those produced by the more conventional methods of refraction surveying and it is found that the data are of insufficient quality to facilitate a geological interpretation to be made with the -p method alone and that the method is of no use with the poorest quality data. Recourse to the conventional methods is found to be necessary, and the results obtained verify previous results from other work
Diagnostical meaning acute phase proteins in cerebrospinal liquid in children with neuroinfections
No full textIn the article presented results of the examination of acute phase proteins in cerebrospinal liquid in 237 children with meningitis and encephalitis viral and bacterial etiology. The dependence between the level of acute phase proteins in cerebrospinal liquid and etiology of neuroinfectional process, the severity of brain damage and the process stage was determined. Diagnostic and prognostic efficiency of the acute phase proteins (C-reactive protein, albumin, alpha-1-antitripsin, alpha-2-macroglobulin, gaptoglobin) examination in children with neuroinfections was specified. Developed method of express diagnostics of the severity of inflammatory damage of the brain in bacterial meningitis in children by determination in cerebrospinal liquid alpha-2-macroglobulin is described
Major and minor lymphocytes subpopulations in peripheral blood and cerebrospinal fluid of children with meningitis
No full textIntroduction. The analysis of current publications indicates at our insufficient understanding of subpopulation composition of lymphocytes in peripheral blood and cerebrospinal fluid (CSF) during pediatric neuroinfectious diseases. It has been found that the main lymphocyte populations are divided into many small (minor) subpopulations.The purpose of this research was to assess percentage of major and minor blood and CSF lymphocyte subsets in children with aseptic viral meningitis (AM) or bacterial purulent meningitis (BM).Materials and methods. Phenotyping of blood and CSF lymphocytes of children aged from 4 months to 17 years diagnosed with AM (n = 86) and BM (n = 39) was carried out by using flow cytometry. As a comparison group, we analyzed peripheral blood and CSF samples collected from children with acute respiratory viral infections (ARVIs) associated with syndrome of meningism (n = 27). There was evaluated percentage of the major cell subpopulations (CD3+ T-lymphocytes, T-helpers — CD3+CD4+ Th, cytotoxic T-lymphocytes — CD3+CD8+ CTL, natural killer cells — CD3-CD16+CD56+ NK, B-cells — CD3-CD19+), as well as minor lymphocyte subsets (double positive (DP) (CD3+CD4+CD8+), double negative (DN) (CD3+CD4-CD8-) T-cells, NKT (CD3+CD16+CD56+), CD3-CD8+ NK, CD3+CD8dim and CD3+CD8 8bright).Results. It was found that the acute period of BM and AM vs. the comparison group (ARVI) was characterized by significant differences in the blood and CSF composition of major and minor lymphocyte subsets. In particular, blood T-cells, Th, CTL, NK, NKT, DN, CD3-CD8+ NK, CD3+CD8bright and CD3+CD8dim dominated in parallel with significantly lowered B-cell frequency in AM vs. BM. In the CSF of children with AM, T-cells and Th prevailed, whereas count of B-cells and CD3-CD8+ NK was lower compared to those in BM. In addition, further differences were revealed in CSF and blood cell subset composition depending on nosological entity, while maintaining differences in some major and minor lymphocyte subpopulations lacked in the comparison group. Calculating the CSF/blood ratio for the major and minor lymphocyte subsets uncovered the prevalence for the majority of cell subpopulations (the coefficients ranged from 1.2 to 16.4) in the CSF of the comparison group (ARVI), except B-cells, NK and CD3-CD8+ NK (coefficients ranged from 0.07 to 0.31). AM and BM were featured with various changes in the CSF/blood ratio found for most of the studied subpopulations in the acute period as well as the recovery phase highlighted with characteristic traits for each nosological form.Conclusion. The data obtained indicate about finding specific features in the activation of systemic and intrathecal immune response during viral and bacterial meningitis in children, which may be used as an additional differential diagnostic criterion
