The adaptation challenges of foreign students in TPU from the perspective of cross-cultural communication

The goal of Russian universities is to join the international scientific community. This aim is closely connected with the attraction of foreign students to study in Russia. TPU is one of the greatest centres to attract foreign students in our region. There are different programs of the adaptation to life in Tomsk and university life for foreign students. For our research it was important to learn about the features of the adaptation of foreign students who are away from home. We held a survey with 22 foreign students. In our research we identified important problems faced by foreign students: problem with communication; the problem of isolation living in separate hostels and studying; climate component in the process of the adaptation. In conclusion, we can say that Tomsk can be considered prosperous and hospitable zone for foreign students. Задача российских вузов - выйти в международное пространство и прочно утвердиться в нем. Эта цель тесно связана с привлечением иностранных студентов для обучения в России. ТПУ представляет собой один из крупнейших центров по привлечению иностранных студентов в своем регионе. Для иностранных студентов университетом предусматриваются различные программы адаптации к жизни в городе и к университетской жизни. Для нашей работы представлялось важным узнать об особенностях адаптации иностранных студентов, находящихся вдали от дома. Мы провели анкетирование 22 иностранных студентов. В нашей работе по опросу были выявлены важные проблемы, с которыми сталкиваются иностранные студенты: проблема с коммуникацией; проблема социальной замкнутости: отдельное проживание и обучение; климатическая составляющая процесса адаптации. В заключение мы можем сказать, что Томск может считаться процветающей и гостеприимной зоны для иностранных студентов

Factors for increasing strength of composite materials based on fine high-calcium fly ash

Industrial high-calcium fly ashes obtained by burning Kansk-Achinsk coal at a thermal power plant and selected from different fields of electrostatic precipitators of an ash collecting plant were studied as the basis for composite binders (CB). The main factors influencing the properties of such CBs are the particle size, the concentration of superplasticizer at a water:binder (w/b) ratio of 0.25, and the proportion of HCFA in the mixture with cement. In particular, for cementless CBs at w/b 0.4, it was found that a change in the particle size d90 from 30 μm to 10 μm leads to an increase in compressive strength by more than 2 times – from 5.5–14 MPa to 11–36 MPa, accordingly, with a curing age of 3–300 days. The 0.12% additive of Melflux 5581F superplasticizer at w/b 0.25 increases the compressive strength – up to 14–32 MPa and up to 24–78 MPa, accordingly. The HCFA-cement blends were investigated in the range of 60–90% HCFA and the maximum compressive strength 77 MPa at 28 days of hardening was found at 80% HCFA. On the basis of 80% HCFA blend with the 0.3% addition of Melflux 5581F and 5% silica fume, the specimens of ultra-high strength (108 MPa at 28 days of hardening) were obtained

Experience of Self-Translation of a Lyric Poem from Russian into Erzya by a Bilingual Poet

The purpose of the study is to consider the experience of self-translation of a lyric poem from Russian into Erzya by a bilingual poet. An analysis of the experience of automatic translation from Russian into Erzya allowed us to come to the conclusion that each translated work has its own “code of behavior,” which makes it uniquely withstand the translation procedure. The “code of behavior” of a poem consists of a number of factors - genre, theme, main idea, motives, image of the lyrical hero, the author’s personality, national and non-national signs and symbols, the time of creation of the text and the time of its translation. All this affects how the work will enter the space of another language. It may ‘agree’ to a new linguistic shell and then retain its original concept, without losing anything, but also without gaining anything, or it ‘may begin to resist’ the new sound, which will cause the birth of new meanings, and therefore new images, and complicate the nature of artistic expression. The native language, as a language genetically inherited from parents, conveys to a person the so-called “innate ideas” recorded in the gene pool of his ancestors. And they play an important role both when creating an original work and when translating it into another language. Research methods: descriptive, genetic, comparative

Petromagnetic features of sediments at the Mesozoic-Cenozoic boundary: Results from the Gams section

The paper continues a cycle of petromagnetic investigations of epicontinental deposits at the Mesozoic-Cenozoic (K/T) boundary and is devoted to the study of the Gams section (Austria). Using thermomagnetic analysis, the following magnetic phases are identified: goethite (TC = 90-150°C), hemoilmenite (TC = 200-300°C), metallic nickel (TC = 350-360°C), magnetite and titanomagnetite (T C = 550-610°C), Fe-Ni alloy (TC = 640-660°C), and metallic iron (TC = 740-770°C). Their concentrations are determined from M (T). In all samples, ensembles of magnetic grains have similar coercivity spectra and are characterized by a high coercivity. An exception is the lower coercivity of the boundary clay layer due to grains of metallic nickel and iron. With rare exceptions, the studied sediments are anisotropic and generally possess a magnetic foliation, which indicates a terrigenous accumulation of magnetic minerals. Many samples of sandy-clayey rocks have an inverse magnetic fabric associated with the presence of acicular goethite. The values of paramagnetic and diamagnetic components in the deposits are calculated. According to the results obtained, the K/T boundary is marked by a sharp increase in the concentration of Fe hydroxides. The distribution of titanomagnetite reflects its dispersal during eruptive activity, which is better expressed in the Maastrichtian and at the base of the layer J. The along-section distribution of metallic iron, most likely of cosmic origin, is rather uniformly chaotic. The presence of nickel, most probably of impact origin, is a particularly local phenomenon as yet. The K/T boundary is not directly related to an impact event. © Pleiades Publishing, Ltd. 2008

Influence copolymers of ethylene with vinyl acetate on the physicochemical properties of Bitumen

The results of experiments are presented concerning the modification of road bitumen by ethylene copolymer with vinyl acetate (EVA). This polymeric additive make a strong structure-forming influence on bitumen. At that the penetration value changes most rapidly at 25 °C. The higher the concentration of copolymer and the content of the ester groups in it, the less the penetration depth of the binder needle. The introduction of excess amount of copolymers with vinyl acetate groups develops a spatial structure conjugated with asphaltene associates, and providing the stability of all bitumen heterogeneous system. The reduction of elongation and brittleness temperature is revealed at the introduction of low molecular EVA, which allows to obtain the binders with improved low temperature properties. The most intensive change of properties is achieved by the introduction of EVA into bitumen with the molecular weight of 25,000, which is manifested in softening temperature increase with brittleness temperature reduction, and the extension of plasticity range by 8-20 °C. At the same time the introduction of granulated EVA into bitumen with high molecular weight leads to a significant increase of softening and brittleness temperature and ductility interval decrease. The study results showed that the bituminous compositions modified by EVA with a high content of vinyl acetate groups are somewhat inferior to the softening temperature and the extensibility of the compositions, modified by EVA with a low content of ester groups, because of the greater initial plasticity of the copolymer in the second case

Surface functionalization of titanium with silver nanoparticles

This study aims to investigate the most efficient ways for metallic samples functionalization with silver nanoparticles (AgNPs). Three different techniques of surface functionalization have been used for the coating of titanium metal, i.e. the sessile drop method (evaporation), dip-coating and electrophoretic deposition (EPD). AgNPs stabilized with polyvinylpyrrolidone had a spherical shape and the metallic core diameter, charge and polydispersity index were 70±20 nm, -15 mV and 0.192, respectively. SEM analysis revealed that AgNPs were homogeneously distributed over the entire surface and did not form the particle agglomerates only in case of EPD. Thus, EPD method and spherical AgNPs can be used for further investigation concerning the preparation of biocomposites with antibacterial and bioactive properties
