Mobility coefficients in the systems of magnetic dipolar particles
In this paper, we present our first results on the mobility coefficients in the systems of magnetic dipolar particles. In our study, we investigate the influence of chain formation and polydispersity of particles on self-diffusion. The work is purely theoretical and combines direct calculations with the density functional approach to calculate equilibrium densities of chains. We study mainly bulk systems. It is shown that the formation of chains leads to the average decrease of mobility in monodisperse systems, but in the case of bidisperse particle size distribution, the particle mobility becomes a function of the fractional composition. The mobility coefficients obtained here are important for calculating the diffusion coefficients in case of gradient-induced diffusion (be that of the field or density gradient) in magnetic fluids with chain aggregates
Search for axioelectric effect of 5.5 MeV solar axions using BGO detectors
A search for axioelectric absorption of solar axions produced in the reactions has been performed
with a BGO detector placed in a low-background setup. A model-independent limit
on an axion-nucleon and axion-electron coupling constant has been obtained: for 90% confidence level. The
constrains of the axion-electron coupling have been obtained for hadronic axion
with masses in (0.1 - 1) MeV range: .Comment: 6 pages, 4 figures, to be published in EPJ C. arXiv admin note:

Search for solar axions produced by Compton process and bremsstrahlung using the resonant absorption and axioelectric effect
The search for resonant absorption of Compton and bremsstrahlung solar axions
by Tm nuclei have been performed. Such an absorption should lead to the
excitation of low-lying nuclear energy level: Tm Tm Tm (8.41 keV). Additionally the
axio-electric effect in silicon atoms is sought. The axions are detected using
a Si(Li) detectors placed in a low-background setup. As a result, a new model
independent restrictions on the axion-electron and the axion-nucleon coupling:
and the axion-electron
coupling constant: has been obtained. The
limits leads to the bounds 7.9 eV and 1.3 keV for the
mass of the axion in the DFSZ and KSVZ models, respectively ( C.L.).Comment: 6 pages, 3 figures, contributed to the 9th Patras Workshop on Axions,

ИСЛАМ И КРЫМСКИЕ ТАТАРЫ ПОСЛЕ 2014 ГОДА
The article is devoted to the analysis of the religious situation among the Crimean Tatars, which came after events of the spring 2014. The article deals with the change in the identity structure of the Crimean Tatars and with the perception of the role of Islam in the life of the people. The assessments of respondents regarding changes in conditions in the development of Islam inCrimeaand the situation in the intra-Muslim dialogue are given within. The author draws attention to the dominance of survival / self-preservation values among the Crimean Tatars, and to the growing influence of traditional values, among which an important role is assigned to Islam.Статья посвящена анализу религиозной ситуации среди крымских татар, сложившейся после известных событий весны 2014 года. В ней рассматривается изменение структуры идентичности крымских татар, представление о роли ислама в жизни народа и изменения, имевшие место в религиозной сфере в течение последних нескольких лет. Статья написана по результатам фокус-группового исследования «Ценности и потребности крымских татар», проведённого автором в январе 2017 года. В работе ставится вопрос об актуализации конфессиональной составляющей в структуре идентичности крымских татар и по итогам исследования делается вывод, что этот процесс носит преимущественно декларативный характер. Возрастает и влияние традиционных ценностей, среди которых важная роль отводится исламу
“... And Their Mosques From Churches of God to Build in Distant Places”: to Qquestion of Formation of Interethnic and Interfaith Borders in Western Siberia in 18<sup>th</sup> Century
The process of building ethno-religious boundaries in the 18th century in the social space of Western Siberia is considered on the example of the provincial center — Tobolsk. The relevance of the study is due to the transformation of ethno-confessionalism from a cultural phenomenon into an instrument that can be used for political purposes in modern Russia. One of the methodological research tools is the method of analysis of the “new local history”, which allows you to create a holistic perception of the study of the social life of the past “at a local object”. The main stages of the state ethno-confessional policy in the 18th century are highlighted. The facts of the forced Christianization of Muslims are clarified. The authors draw attention to the role of the personal (subjective) factor in the processes under study. On the example of the activities of Metropolitan Sylvester Glovatsky and the governor F. I. Soimonov, the vector of the development of interfaith relations is considered, which often depends on the foresight and ideological attitudes of local authorities. Particular attention is paid to government decrees reflecting the position of the state in the ethno-religious sphere. The features are revealed and the main stages of the process of Christianization of Siberian Muslims during the 18th century are highlighted. The process of formation of interfaith boundaries in the multiethnic Siberian region is analyzed. The historiography of the topic under study is presented
Composition of Population of Tatar Settlement of Tobolsk according to the “Census Book of Tatar Yurts in River Irtyshu” (Second Half of 17th Century)
Based on the materials of the Russian State Archive of Ancient Acts (RSAAA), questions of the ethnic composition of the main city of Siberia - Tobolsk in the XVII century are examined. Attention is paid to the characteristics of various groups of the urban Turkic population. A review of census books on Siberia of the 17th century is completed. Particular attention is paid to the analysis of the “Census book of Tatar yurts in river Irtysh”, introduced by the authors into scientific circulation. The results of a comparative analysis of data from the census book of 1682 with other sources are presented. The question is raised about the features of the population formation of the Tatar settlement of Tobolsk. It is proved that the formation of the Tatar urban population included various categories of the Turkic population. A classification and characterization of such population groups of the city of Tobolsk as service Tatars, feudally dependent Tatars, and Bokharans are proposed. The novelty of the study is determined primarily by the lack of knowledge of the ethnic composition of Siberian cities, in particular, in the 17th century. The relevance of the study is due to the need to identify ways of forming the population of the Siberian capital
