SYNOPSISCT scans were performed on 72 consecutive patients with a functional psychosis, and compared with 50 community controls. There was a specific difference in lateral ventricular area between these two groups but it accounted for only 11% of the variance in this measure. In contrast, racial and sexual differences in the ventricular-brain ratio (VBR) related to differences in intra-cranial area. It is argued that analysis of variance, using lateral ventricular area and intra-cranial area, is more informative than VBR in examining these structural changes in functional psychoses.

The relationship of the resistivity versus synthesizing temperature of sol-gel YBa2Cu3O7-x samples, with Tc 91K, was studied while synthesizing in flowing oxygen atmosphere. A set of high temperature -T curves were obtained for the whole process. After four rounds of synthesizing, the resistivity of the sample was =1.00×10-3cm at room temperature. The -T curve of the last round also showed that the orthorhombic to tetragonal phase transformation of the sample occurred around 600oC that is lower than the YBa2Cu3O7-x sample prepared in ambient atmosphere. Other measurements such as X-ray diffraction, SEM measurement, low temperature R-T and M-T measurement were also taken to get more information of these samples.

The article is devoted to the analysis of the theoretical approaches of the theory of human capital and its definitions involving the coverage of concepts in historical retrospective. The relevance of the issue is due to a rather serious growth of the terminological field, which complicates the further theoretical conceptual development. Therefore, the aim of the article is to systematize existing approaches and basic concepts of human capital based on changes caused by interchangeable technological structures. The research methodology is based on the use of content analysis, historical and structural approaches. The research basis is classical studies of the theory of human capital as well as the work of Russian scientists over the past ten years. After the collection of scientific papers representing the conceptualization of theories of human capital was completed, selective work was analyzed (the selection was made by experts), which are of interest for systematizing and correlating the concepts of human capital with the theory of technological structures. Through content analysis, a multi-axis map of the «human capital» perception formed from the middle of the 20th century to the present moment was constructed. Such technological arguments were developed and described as «trends affecting the market and the nature of labor» and «education», as technological changes provoke sharp changes in the labor market and requirements for human capital. Moreover, the factors of its genesis and accumulation are changing. As a result, a systematization of human capital concepts was also proposed based on the criteria for interconnection with a change in technological patterns. This study can serve as the basis for further research on human capital in the context of technological and world economic structures. As an option to deepen this direction, we can offer an analysis of existing concepts of human capital based on the criteria for the relationship of its development with structural changes in the global economy.

The author uses the data of sociological researches conducted at the Institute of sociological research of the Russian Academy of Sciences for two dec-ades, one of the tasks of which was to study and analyze the attitude of individuals, groups and sec-tors of the population to the ongoing socio-structural changes in society. The research materials made it possible to analyze the features of the for-mation of new layers and groups in the modernizing Russian society and trace the change vector in their relationships. Secondary analysis of the obtained data allowed the author to identify several condi-tional periods of development of the Russian social system. The basis for highlighting these periods was the respondents' opinions on the criteria of social group membership in the modernizing Rus-sian society, on the relationship of new social groups, as well as the nature of the respondents' behavior strategies in the changed conditions of life. The author considers social and structural transfor-mations as a consequence of the general moderni-zation of the Russian social system.

In this paper, effect of FBG coating in curing monitoring of composites was studied. In the experiment, three kinds of sensors were embedded in the composites. Excursion of the wavelength and temperature was tested in the whole curing process. 3-point bending test of composites which FBG was embedded in was done. Results showed that FBG could be exactly reflecting the relationship of stress and strain in bending state of composites. After cured, composites were heat up to 180°C for 1 hour. Sectional appearance of different optic fibers in room temperature and high temperature was got by optical microscope.

The review contains data from large-scale foreign and Russian studies of the epidemiology of osteoarthritis (OA). It considers the role of modifiable and non-modifiable risk factors for OA, such as age, sex, hormonal status, obesity, etc. There are data on genetic susceptibility to OA and on congenital anomalies that contribute to joint structural changes. Data on the impact of racial and ethnic factors on the development and progression of OA are analyzed. The role of metabolic disorders in the pathogenesis of this disease is highlighted. Data on the relationship of OA to patients' professional activities are summarized.

Freeze-thaw made the microstructure of the soil produce a certain degree of damage, which was relevant with the soil water content. 6 kinds of remolded soil of the water content was prepared, at low temperature of freezed, in room temperature of melt, after not consolidated non-drained triaxial compression test, the soil shear strength parameters was determined. The results show: after thawed, soil shear strength had reduced significantly, and water content exerted such a pronounced effect on strength of reducing amplitude. Accordingly, the relationship of shear strength reducing after thawing of remolded soil and the water content was set up preliminarily.

The article analyzes the relationship between structural changes and economic growth in the world economy and Russia. The authors note the emergence of a growth model in the world economy based on the complementarity of economic policies aimed, on the one hand, at the development of fundamental foundations of economic growth (institutions, human capital, infrastructure, macroeconomic stabilization), and, on the other hand, at initiating growth through structural reforms (even under stable foundations). Analyzing the trends of structural changes in the world economy, the authors consider new forms of structural policy, in particular, the ones oriented at the issue of identification of sectors — potential drivers of economic growth using the portfolio approach. A preliminary version of the model of Russian economy based on the multi-sector variety of the Thirlwall’s law is presented in the paper.

We have investigated the relationship of concanavalin. A binding to the cell surface of normal and transformed cells and the subsequent agglutination of the transformed cells. At room temperature almost no differences could be detected in agglutinin binding between transformed and untransformed cells. At 0°C, however, where endocytosis was negligible, the transformed cells bound three times more agglutinin. However, transformed cells and trypsin-treated normal cells do not agglutinate at 0°C although the amounts of agglutinin bound at 0°C are sufficient to permit agglutination when such cells are shifted up to room temperature. Both transformed and trypsin-treated normal cells show a marked increase in agglutination at 15°C as compared to agglutination at 0°C. From this, as well as the observation that mild glutaraldehyde fixation of the cell surface inhibited agglutination but not agglutinin binding, it was concluded that concanavalin A-mediated cell agglutination requires free movement of the agglutinin receptor sites within the plane of the cell surface.
