    Анализируя средства массовой информации Латинской Америки и результаты опросов, проведенных в Боливии в декабре 2014 г., автор пытается выявить ключевые моменты дискуссии о событиях в Украине и определить, насколько Россия может рассчитывать на поддержку государств региона в своем противостоянии с Западом, что именно влияет на наличие или отсутствие данной поддержки.

    This is English translation of the Thesis, originally written in Russian and remained unpublished. The Thesis was an attempt to combine data from three previously independent areas: the structure and kinematics of stellar populations of the Galaxy, photometric and dynamical models of galaxies, and models of the dynamical and physical evolution of galaxies. The Thesis was completed in November 1971 and defended in March 17, 1972 for the degree of Doctor of Science in astronomy and celestial mechanics. This synthesis was made with the goal to understand better the vast topic of the structure and evolution of galaxies. The main results of the study can be divided into methodical and astronomical. The methodical results include: (i) extrapolation of the mass distribution function beyond the Sun���s distance, and the determination of the circular velocity at the Sun���s distance from the Galactic centre; (ii) conditions of physical correctness of models are developed, and the generalised exponential model is suggested; (iii) a method has been developed to construct spatial and hydrodynamical models of stellar systems, using a combination of observational data on populations, and data on physical evolution of populations. The main astronomical results are: (i) spatial and hydrodynamical models of the Galaxy and the Andromeda galaxy M31 are elaborated in several approximations; (ii) the dynamical evolution of the Galaxy is reconstructed using kinematical characteristics of stellar populations of different ages; (iii) on the basis of stellar evolutionary tracks and star formation function, a theory of the evolution of galaxies is elaborated. The basic conclusion of the study is: it was impossible to reproduce the observed rotation curves of galaxies with known stellar populations.

    The detection of small quantities of proteinuria has gained significance as multiple studies have demonstrated its diagnostic, pathogenic, and prognostic importance. More than 260 samples of urine taken from the patients suffering chronic kidney disease (CKD), diabetes and hypertension have been analysed in the certified laboratory, with urine analyser H-50 (urine test strips) and with an optoelectronic setup specially designed for this study. Albumin, protein and creatinine concentrations have been determined in the laboratory and the data thoroughly analysed with the aim to find new approaches to tackle the lowered level proteinuria problems. Special attention has been paid to a particular screening focus group of 16 patients all having normal or slightly abnormal levels of albumin in parallel with enhanced levels of total protein (45% cases) up to 0.4 g/L. A fair correlation between the maxima in the protein, protein/creatinine, protein/albumin values and CKD in the focus group has been observed. The urine test strips method gave 94% negative false results for the focus group whereas the new sensor has shown in all cases the presence of proteins. The sensor signals higher than the mean in this focus group were obtained for the donors with the diagnosed CKD and some other diseases. The new method is based on the optical absorption measurements (285 nm) in the protein fractions received with use of the commercial desalting columns PD-10. The method can be applied in the wide region of protein concentrations from ≤0.1 g/L up to the levels of severe proteinuria (~10g/L). © 2016 Samara State Aerospace University (SSAU).

    The article deals with the problem of the existence of the Russian language at the end of the 20th century against the background of socio-cultural and political changes in society. The author identifies three main lexical cycles in the formation of the communicative portrait of the epoch. The change in the appearance of the language is associated with the processes that have received the greatest development in the 20th century: coding and codification; recoding - decodification - new codification, etc. The increased role of the administrative-territorial sub-paradigm of the Russian language in the creation of new speech models is noted. The author emphasizes that the 20th century influenced the change of language sign. The article deals with the problem of the sociolinguistic status of the Russian language in the pre-revolutionary period in the Soviet and post-Soviet times. The author says about the loss of the position of the Russian language at the end of the 20th century. Its role in the trance-ethnic space of post-Soviet Russia is noted. The author makes conclusions about the prospects of using the Russian language in Western Europe.

    The etymology of the noun baidak [river boat, barge] is somewhat obscure. The purpose of the article is to trace the etymology of the lexeme included in its title. It is absent from the literary language. We think that baidak meaning ‘river boat/river vessel’ is related to the verb idti [to go]. We can divide this noun into prefix ba-, stem -id-, and suffix -ak. Step by step, citing examples, we prove that these morphemes could exist in the Russian language. Thus the morphological and semantic analysis with elements of comparative research of the noun baidak helps us to clarify its etymology. The theoretical value of the results of research is an opportunity to use them when studying other regional nominations. Their practical value lies in the linguistic experiment that helped us define the etymology of this dialect word and draw the attention of other scholars to the unique cultural landscape of the language.
