Mari of Bashkortostan in 1970-2010: Demographic and Linguistic Aspects of Ethnic Development

The issues of ethnodemographic and ethnolinguistic development of the Mari population in Bashkortostan are considered. Particular attention is paid to the characteristics of the ethno-demographic situation in the regions of the country with a significant number of the Mari ethnic group. The results of a comparative analysis of the natural reproduction of the Mari in comparison with other ethnic groups in the republic are presented. The question is raised about the ethnolinguistic identity of the Mari population, which, according to census data, is losing its national language. The novelty of the study is seen in the fact that for the first time an analysis of the demographic and linguistic aspects of the development of the Mari population in the regions of the Ural-Volga region was carried out. The relevance of the study is due to the fact that the issue of demographic development of the peoples of Russia at the present stage is becoming not only a social, but also a political and strategic problem. The authors elaborate on the results of interethnic interaction of the Maris in the zone of ethnocultural contacts. It is proved that, despite the high birth rate, the demographic development of the Maris has a negative balance. A review of the ethno-linguistic development of the Mari population is carried out taking into account the administrative-territorial division. It is concluded that the emerging trend of urbanization of the Mari negatively affects the preservation of the native Mari language

The future of Russian-arab relations in the context of the political crisis in the middle east

© Serials Publications. The urgency of the problem is caused by the growing role of Russia in the context of the deteriorating political situation in the Middle East, which, in turn, reveals a fundamentally important issue. Is there a future for Russian-Arab relations and what is their international legal basis, especially in the context of the political crisis in Syria? The purpose of this article is to identify and study trends that indicate the growth of Russian influence in the Middle East, as well as analysis of the main areas of joint cooperation and legal framework of multilateral Russian-Arab relations. Leading approaches to the study of this problem are political modeling and forecasting in combination with the structure functional study of the object of cognition. As a result of the study, we came to the following main conclusions: 1) the "Arab view" in relation to Russia is ambiguous and directly depends on the political and economic goals of a particular state of the region; 2) legal framework of Russian-Arab relations is quite diverse and is conditioned by the main areas of Russia's cooperation with the countries of the Arab East (counter-terrorism, arms transfers, construction of energy facilities); 3) activation of Russia's position in Syria has formed a true balance of power in the region, having filled up the void of the failing pro-Western and, above all, pro-American influence on the political alignment of forces in a number of Arab states. Materials of this study may be useful for analysts, orientalists, international lawyers, as well as teaching staff of higher education institutions, specializing in teaching International relations and International law

Manifestation of Identity among Diaspora Groups in Russian Multiethnic Region (on Example of Bashkortostan Jews)

The problems of identity manifestation in ethno-disperse groups, in particular Jews, in the Republic of Bashkortostan as one of the polyethnic Russian regions are considered. The study is based on the analysis of ethnolinguistic identity of Jews in the region in the late 19th, during 20th and early 21st centuries. It is noted that in the late 19th - early 20th centuries the ethnolinguistic identity of the Jewish population remained very high, but during the Soviet period, living in a multi-ethnic Republic, highly urbanized Jewish ethnic group, adapting to the local Russian-speaking environment, largely lost the native language of their nationality. Based on the results of a comparative analysis of the all-Union and all-Russian population censuses, it is proved that, despite the measures taken to revive the native languages, in the post-Soviet period, compared with the Soviet one, Jewish ethno-disperse group had no special changes in the ethnolinguistic identity - the recognition of the Jewish language as a native language remained very low. It is emphasized that the Jewish population living in Bashkortostan unlike representatives of other ethnic groups in the region (Bashkirs, Tatars, Russians, etc.), is mostly aware of the all-Russian identity more than regional

Double magnetic resonance in MnCO3

© Kazan Federal University (KFU). Results of experiments on MnCO3 investigations by double magnetic resonance are presented. Additional mode of oscillation has been observed in a created Bose-Einstein condensation of magnons state in MnCO3. The properties of observed signals are similar to Goldstone modes

Annealing of PrF3 nanoparticles by microwave irradiation

The influence of microwave irradiation on the recovery of nanocrystalline PrF3 powders has been experimentally analyzed by nuclear magnetic resonance (NMR) at T = 1.5 K. It is established that the relaxation times of 141Pr and 19F nuclei rise significantly with an increase in the hydrothermal-treatment time, whereas the 141Pr NMR spectra narrow, which indicates a decrease in the number of defects in the lattices of nanosamples. © 2014 Pleiades Publishing, Ltd

The spin kinetics of 3He in contact with nanosized crystalline powders LaF3

© Published under licence by IOP Publishing Ltd. The spin kinetics of 3He in contact with nanosized crystalline powders LaF3 has been studied by NMR methods at the temperature 1.5 K. The 3He longitudinal relaxation time increases proportionally to the magnitude of the external magnetic field and the transverse relaxation time does not depend on the magnetic field. Relaxation of the gaseous and liquid 3He in contact with nanosized crystalline powder LaF3 takes place by the 3He adsorbed layer. The nuclear magnetic relaxation of adsorbed 3He layer on the surface of LaF3 nanoparticles is due to the two-dimensional spin-diffusion motion

Size effect in the (PrF3 nanoparticles-3He) system

Spin kinetics of adsorbed and liquid 3He in contact with crystalline nanopowders of the Van Vleck paramagnet PrF3 at a temperature of 1.5 K has been studied by nuclear magnetic resonance. The correlation between the parameters of the nuclear magnetic relaxation of 3He and the sizes of the sample particles has been found. A qualitative model of the magnetic relaxation of 3He describing the experimental results has been proposed. © 2013 Pleiades Publishing, Ltd

Magnon BEC in antiferromagnets with Suhl-Nakamura interaction

From atomic physics one knows the phenomenon of Bose-Einstein condensation (BEC), where a macroscopic ensemble of particles occupy coherently a single state. Similar phenomena were observed for different types of quasiparticles in condensed matter. Here we present the results of investigations on the BEC of elementary magnetic excitations - magnons - in antiferromagnets with a dynamical frequency shift. © 2014 Springer Science+Business Media New York

Comments on the cross-relaxation effect between adsorbed 3He and PrF3 nanoparticles

© 2015 AIP Publishing LLC. The spin kinetics data of 3He in contact with PrF3 and LaF3 nanosized powders are reported. All experiments have been carried out by pulse NMR methods at temperature 1.5K. The analysis of obtained data testifies in favor of cross-relaxation presence in the nuclear spin-lattice relaxation data, which takes place between 3He and 141Pr nuclei

Generalized Global Defect Solutions

We investigate the presence of defect structures in generalized models described by real scalar field in $(1,1)$ space-time dimensions. We work with two distinct generalizations, one in the form of a product of functions of the field and its derivative, and the other as a sum. We search for static solutions and study the corresponding linear stability on general grounds. We illustrate the results with several examples, where we find stable defect structures of modified profile. In particular, we show how the new defect solutions may give rise to evolutions not present in the standard scenario in higher spatial dimensions.Comment: RevTex, 10 pages, 2 figures; version to appear in EPJ
