Changes in Chemical Composition of Natural Waters in Response to Technogenic Load (the Case of Tomsk City, Russia)

The article provides the analysis of chemical composition of the ground and surface waters on the left bank of the river Tom’ within Tomsk area. This study is being conducted in context of active development of the area. The results obtained are compared with the analysis data of the earlier periods. It is concluded that the closed lakes have more changes in water chemical composition, which is caused by increasing content of petrochemicals, heavy metals, phosphorus and nitrogen compounds due to growing economical activities near the water bodies

Phase formation processes and synthesis of solid solutions in Ca-R-Nb-M-O systems

During the study of the phase formation process in Ca-R-Nb-M-O systems (R=La, Bi, M=Mo, W), an attempt was made to obtain single-phase compounds of CaRNbMO8 composition by the standard ceramic technique. In addition, samples based on LaNbO4, CaWO4, BiNbO4 were also synthesized by the standard ceramic technique. The phase composition of the samples was studied by XRD analysis. The electrical conductivity of the obtained solid solutions and potential composite materials was investigated by impedance spectroscopy

Educational Migration Bridge: From Metaphor to Project

The purpose of the article is to analyze the topical problem of educational migration and ways to solve it. The article identifies factors preventing from successful adaptation and socialization of foreign students in recipient country as legal, pedagogical, psychological, lingvo-communicative are identified. Minimization of negative factors actualized the integrated strategy of educational migration «bridge construction» development aimed at solving tasks of migrants’ integration in Russian labour market, providing them with all-round support in getting education, improving professional qualification, adaptation and socialization. The term «bridge» is metaphorically used as an artificial, virtual «construction» functioning as a means for educational migration support of citizens.The experience of the Orenburg State University in development and realization of the longterm integrated strategy of educational migration «bridge construction» presented within the Strategic Academic Leadership Program «Priority 2030» is studied. Regarding the potential of the University and Orenburg region the ways of educational migration «bridge construction» are determined: introduction of educational migration interactions into mission and policy of the university; development of open university migration interactions network structures; implementation of educational migration interaction based on norms, values and ideals of person’s lingvo-communicative culture. The practical steps for the strategy realization within the project «Educational migration bridge» are described: formation of the united scientific, educational and cultural environment based on mutual activity in international scientific and educational community; arrangement of universities regional consortium for informing applicants from Asian countries, for training and living in universities campuses; establishment of the Faculty of foreign students’ education and digital educational platform ensuring logistics and student educational improvement management; development and realization of module network programs for foreign students; realization of additional educational programs in OSU Linguistic center. The authors analyze the main indicators of the project effectiveness: quantitative and qualitative results of the Faculty of foreign students’ education activity in training Russian and culture; establishment of the Orenburg branch of Foreign Students Association, students’ involvement in various interaction forms and special career guidance events; scientific and methodological support for teachers. Realization of the strategy implies creation in OSU in the nearest future a specific environment including social infrastructure for foreigners

Differences in risk behaviours and HIV status between primary amphetamines and opioid injectors in Estonia and Russia

Background and objective People who inject drugs (PWID) account for over half of new HIV infections in Eastern Europe and central Asia, where opioids continue to be the dominant illicit drugs injected. Stimulants including amphetamines (ATS) have been associated with HIV infection risk in several settings. We sought to examine whether primary ATS injection was associated with greater HIV risk, compared to opioid injection in two European locales with significant HIV epidemics. Methods PWID in Kohtla-Järve and St. Petersburg were recruited using respondent-driven sampling in 2012–2013. Survey data on demographic characteristics, service use, injecting and sexual risk behaviours and HIV-status (and HCV in Kohtla-Järve) were compared between primary opioid and ATS injectors using logistic regression models. Results Of 591 injectors recruited in Kohtla-Järve and 811 in St. Petersburg, 195 (33%) and 27 (4%) primarily injected ATS in each city. In both cities, ATS injectors were younger than opioid injectors, initiated injection later, injected less frequently and were more likely to have been paid for sex. In both cities, PWID had high levels of multiple sex partners. In Kohtla-Järve, ATS-injectors had lower odds of back-loading and greater odds of polydrug use than opioid-injectors. In St. Petersburg, where over half of PWID reported unsafe sharing practices, ATS-injectors were less likely to report these practices. ATS-injection was negatively associated with being HIV positive in Kohtla-Järve (aOR = 0.6; 95%CI: 0.5–0.8) and St. Petersburg (aOR = 0.3; 95%CI: 0.1–0.7). ATS-injection was negatively associated with HCV-reactivity in Kohtla-Järve (aOR = 0.5; 95%CI: 0.3–0.6). Conclusions In both locations, primary ATS injection was associated with lower injecting risk behaviours, lower odds of HIV and being paid for sex compared to opioid injection. Interventions targeting the characteristics and needs of ATS injectors are needed to increase contact with services and reduce sexual and injecting risk. Harm reduction services, including sexual risk reduction, need to be expanded for all PWID in St. Petersburg

Avalanches in self-organized critical neural networks: A minimal model for the neural SOC universality class

The brain keeps its overall dynamics in a corridor of intermediate activity and it has been a long standing question what possible mechanism could achieve this task. Mechanisms from the field of statistical physics have long been suggesting that this homeostasis of brain activity could occur even without a central regulator, via self-organization on the level of neurons and their interactions, alone. Such physical mechanisms from the class of self-organized criticality exhibit characteristic dynamical signatures, similar to seismic activity related to earthquakes. Measurements of cortex rest activity showed first signs of dynamical signatures potentially pointing to self-organized critical dynamics in the brain. Indeed, recent more accurate measurements allowed for a detailed comparison with scaling theory of non-equilibrium critical phenomena, proving the existence of criticality in cortex dynamics. We here compare this new evaluation of cortex activity data to the predictions of the earliest physics spin model of self-organized critical neural networks. We find that the model matches with the recent experimental data and its interpretation in terms of dynamical signatures for criticality in the brain. The combination of signatures for criticality, power law distributions of avalanche sizes and durations, as well as a specific scaling relationship between anomalous exponents, defines a universality class characteristic of the particular critical phenomenon observed in the neural experiments. The spin model is a candidate for a minimal model of a self-organized critical adaptive network for the universality class of neural criticality. As a prototype model, it provides the background for models that include more biological details, yet share the same universality class characteristic of the homeostasis of activity in the brain.Comment: 17 pages, 5 figure

Fine Structure of Avalanches in the Abelian Sandpile Model

We study the two-dimensional Abelian Sandpile Model on a square lattice of linear size L. We introduce the notion of avalanche's fine structure and compare the behavior of avalanches and waves of toppling. We show that according to the degree of complexity in the fine structure of avalanches, which is a direct consequence of the intricate superposition of the boundaries of successive waves, avalanches fall into two different categories. We propose scaling ans\"{a}tz for these avalanche types and verify them numerically. We find that while the first type of avalanches has a simple scaling behavior, the second (complex) type is characterized by an avalanche-size dependent scaling exponent. This provides a framework within which one can understand the failure of a consistent scaling behavior in this model.Comment: 10 page

Comparing frequency and Trueness Scale Descriptors in a Likert Scale Questionnaire on Language Learning Strategies

This paper reports on the comparison of two types of scale descriptors in a questionnaire on language learning strategies.The main purpose of this study was to investigate which type of the two scale descriptors,frequency-based or trueness-based,is better for language learning strategy research. With a few weeks\u27 interval,a questionnaire on learning strategies was administered to 408 EFL learner twice with frequency-based scale descriptors and trueness-based scale descriptors alternately. First, mean differences in the responses obtained from the two different scale descriptors were examined.Second,confirmatory factor analysis was applied to see which scale descriptor of the two shows better fit to the hypothesized model. Finally,equidistance between the categories was checked. Results show that trueness-based scale descriptors elicited slightly higher mean values of responses, which resulted in a better fit to the model. The distances between the categories were almost identical for both scale descriptors.The findings of the current study partially provide supportive evidence for the claim made by Dornyei and his colleagues that trueness-based scale descriptors are preferable to frequency-based counterparts in a questionnaire on learning.But they also show that the latter descriptors are not totally “flawed” as was claimed
