THE SYMBOLIC SYSTEM IN TATAR POETRY OF THE FIRST HALF OF THE TWENTIETH CENTURY: THE TRANSFORMATION OF NOMINATIVE MEANINGS

verifies the term of “nomination” in relation to poetic images-symbols. The interconnection of literary and cultural linguistics methods of analysis through the concept of nominations to the images-symbols made it possible to apply a new theoretical approach to the study of the symbolic system. Methodology: in our study, we rely on the methodology of considering the symbol in the aspect of a system of nominations, which, in our opinion, expands the views on the process of symbolization. Result: Thus, symbols characterize the national peculiarities of poets’ creativity and the artistic world of poetic works, the principles of organizing the subject level and the ideological and semantic potential of works. As a result, symbols have become a kind of “codes” that defines the unique and universal features of Tatar poetry. Applications: This research can be used for universities, teachers, and students. Novelty/Originality: In this research, the model of The Symbolic System in Tatar Poetry of the First Half of the Twentieth Century: The Transformation of Nominative Meanings is presented in a comprehensive and complete manner

Directions to improve economic efficiency of regional production

The paper provides theoretical grounding and the directions for improving the economic efficiency of the regional feedstuff production. The study develops a conceptual model of distributing management functions of feedstuff production between the regional authorities of state sectoral and economic management and the district level. The authors suggest the methodology for calculating potential capacity of intraregional feedstuff market, considering the demands of all categories of agricultural manufacturers. The study examines possibilities for implementing the strategy of diversified growth and development of the intraregional feedstuff market, including the terms of interaction between the large and micro-business inside the industry and cooperation of micro-business feedstuff manufacturers with agricultural production. The authors have developed the methodology for assessing the efficiency of feedstuff production, based on the aggregate estimation of the management organization, conditions for the development of feedstuff production and changes in the feedstuff production and livestock breeding industry.peer-reviewe

対人関係の光と影 : 「絆」の形成、拒絶、そして崩壊の社会心理学的研究

© 2015 Springer Science+Business Media New York. The feasibility of applying thermal analysis to study of oil-containing rocks and organic matter is reviewed. Using heavy crudes from the Ashal'cha and Mordovo-Karmal fields, the potential for analysis of the effectiveness of iron-containing precursors of aquathermolysis catalysts is demonstrated with use of data derived from thermal analysis. The thermal effects detected in the presence of the catalyst precursor, as compared with the original sample, reflect decomposition of the catalyst precursor and degradation processes for the components of the crude oil activated by the catalyst. It is shown that use of thermal analysis is feasible for preliminary selection or optimization of catalyst compositions for in-situ upgrading of crude oils, taking into account the activity of the catalyst relative to certain components of the crude in a specific temperature range

Electron paramagnetic resonance studies of asphaltenes complexes in heavy oils and bitumen

The present paper is focused on the application of some of the multifrequency (9.5 and 94 GHz) continuous wave and pulsed EPR techniques to study the dynamics and structure of asphaltenes and vanadyl complexes from the crude oils and bitumen at near room temperature. The features of the observation of EPR in these systems at high frequencies are pointed out. Longitudinal and transverse relaxation times of asphaltenes and vanadyl complexes are measured. Usage of the data obtained for DNP of protons of crude oils and bitumen is discussed

Features of colloidal disperse structure formation in petroleum bitumen

© 2016, Pleiades Publishing, Ltd.Temperature-modulated differential scanning calorimetry has been employed to analyze the structure-related thermal properties of petroleum bitumen. This method enables one to distinguish between “order–disorder” and glass transitions, thereby making it possible to monitor and identify structure-related phase transformations, the signals from which are invisible or overlapped in the thermograms of conventional differential scanning calorimetry. Bitumen has been shown to be a colloidal disperse system only under certain temperature–time conditions. Its dispersed phase may be represented by aggregates of two types with colloidal sizes. Saturated hydrocarbons form a solid crystalline phase in accordance with the regularities of first-order structural phase transitions and nucleation mechanism of phase separation. Asphaltenes and resins form a solid amorphous phase for a relatively long time as a result of a structural relaxation glass transition by the spinodal mechanism of phase separation

Composition of oils in Vereiskian and Bashkirian carbonate reservoirs of the Akanskoe oilfield in the Republic of Tatarstan

The mineral and organic components of the core material from Vereiskian and Bashkirian deposits of the Akanskoe field in the Republic of Tatarstan have been studied by complex thermal analysis. The occurrence depth intervals with abnormally light oil have been revealed in the Bashkirian deposits. These facts together with the data on the composition of oils (high values of the ratio of light to heavy alkane homologues for heavier and more viscous Bashkirian crude oils, the bimodal MMD character of C 9-C 20 n-alkanes, and enrichment in high-molecular-mass asphaltenes at the bottom of the reservoir) suggest the influx of a lighter oil to the formed Bashkirian deposit. No facts of this sort have been identified for the Vereiskian oil. © 2012 Pleiades Publishing, Ltd

Study of Organic Self-Assembled Nanosystems by Means of High-Frequency ESR/ENDOR: The Case of Oil Asphaltenes

© 2018, Pleiades Publishing, Ltd. An approach to investigate self-assembly of oil disperse systems based on high-field electron nuclear double resonance has been suggested. As exemplified by asphaltenes, the oil components most prone to self-assembly, the formation of planar rather than multilayer structures has been directly evidenced experimentally. The suggested method can be applied to elucidate the self-assembly mechanism in wide range of organic objects

Hyperuricemia as a risk factor for arterial hypertension among the population of the Fergana region of the Republic of Uzbekistan

Today, a lot of data has been accumulated on the role of purine metabolism disorders in the development of a number of diseases, including cardiovascular diseases. However, the results of a large number of epidemiological and clinical studies aimed at detecting the pathogenetic relationship between hyperuricemia (HU) and arterial hypertension (AH) are contradictory. According to the purpose of the study - to study the epidemiological conditions in relation to hypertension in connection with HU and other risk factors in order to be ¬able to plan multifactorial prevention on this basis, we carried out epidemiological study ¬of hypertension due to a combination of risk factors such as HU, impaired carbohydrate tolerance (IHT), pesticideemia, dyslipoproteinemia (DLP), overweight and smoking among rural men ¬and women of working age. We chose a continuous method of epidemiological examination with the measurement of blood pressure, ECG, anthropometric and biochemical studies. To determine the groups for primary, secondary and tertiary prevention, we have established the level of individual risk of developing hypertension. On this basis, a percentile distribution was built and the entire population of men and women was divided into 3 groups: 1-group of moderate risk (84.6%); 2-high-risk group (10.3%) and 3-group of patients (5.1%)

Toward the Asphaltene Structure by Electron Paramagnetic Resonance Relaxation Studies at High Fields (3.4 T)

© 2016 American Chemical Society.A series of 12 asphaltene samples extracted from heavy oils and the oxidized bitumen of different origin has been studied with high-frequency W-band (94 GHz) pulsed electron paramagnetic resonance (EPR) spectroscopy. Transverse (T2e) and longitudinal (T1e) relaxation times of the free radical (FR) and the vanadyl porphyrin (VO2+) were measured for each sample. A significant contribution of the spectral diffusion to T2e has been revealed and ascribed to the dipole-dipole interaction between the FR and VO2+. This indicates that the distance between the FR and VO2+ does not exceed a few nanometers, which means, in turn, that VO2+ can participate in construction of the asphaltene aggregates via the intermolecular interactions
