The magnetic structure of a polycrystalline nanowire at the weak or missing magnetostatic interaction exhibits the special self-organization of magnetization. As is known, the magnetization structure forming in a random crystallographic anisotropy field has a characteristic length range, which involves tens and hundreds of crystallites. This leads to the occurrence of stochastic domains. The induced uniform anisotropy of magnetostatic nature or the texture co-directed with the crystallite anisotropy axes masks the picture of stochastic domains. Nevertheless, as we show, the information on stochastic domains remains in the magnetization structure. The experimental techniques for obtaining information on the magnetic properties of stochastic domains are proposed. © 2017, EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

A comparative analysis of the influence of random fluctuations of the crystallographic anisotropy and surface roughnesses on the pinning of a domain wall in a nanowire has been performed in the framework of the model of a polycrystalline nanowire. The initial magnetization curve and the coercive force for these mechanisms of pinning have been calculated. A criterion has been formulated according to which surface inhomogeneities of the nanowire play the key role in the process of pinning of a domain wall. The analytical results obtained have been verified using computer simulation. © 2011 Pleiades Publishing, Ltd.

Legal regulation of the cultural development of Indigenous Peoples Arctic Siberia - an essential condition to preserve their unique culture. Indigenous Peoples of the Arctic Siberia live compactly in 12 regions of the Siberian Federal District (Russia). Currently there is no specific legal framework to preserve the unique culture of the Indigenous Peoples in the Arctic Siberia Siberian Federal District (Russia). Preserving the unique culture of the Indigenous Peoples of the Arctic Siberia will possible if the legal base will soon be created for this. Need to learn from the experience of the Republic of Sakha (Yakutia) and other regions where the regulatory framework for the conservation of the unique indigenous culture exists and operates in real cultural space of the Indigenous Peoples of the North.

The article is devoted to the problem of formation of positive ethnic identity of indigenous peoples of the Arctic Siberia. In this article are discusses the results of applied research in 2010-2014. Were used focus groups, questionnaires, personal interviews, expert opinion. In the study were directly involved Evenks, compactly living in Krasnoyarsk and in Evenkia. Were identified difficulties in interethnic communication between ethnic groups of indigenous peoples of the Arctic Siberia and the Russian ethnic group. The main reason of difficulties between the Evenks and Russians is that a large number of residents of the city of Krasnoyarsk and the Krasnoyarsk region have no information about the unique culture of the indigenous peoples of the Arctic Siberia. Evenks are afraid that endangered is their own unique culture. Are proposed measures to strengthen state support to preserve the unique culture of the Evenks.

This article focuses on the processes of ethnic and cultural identification and self-identification, which the indigenous peoples of the North of Russia and Siberia, living in the Russian Federation, are currently going through. The post-Soviet cultural practices of preservation of ethnic identity of the small-numbered peoples of Siberia-the Kumandins and the Dolgans -are studied. The conclusion is made that there is not any state language policy aimed at preserving of the Kumandin language and Dolgan language. The Kumandins and the Dolgans have active processes of ethnic identification, but the post-Soviet cultural practices do not relate to these processes. Processes of ethnic and linguistic assimilation are accompanied by post-Soviet practices, where state policy does not increase and does not weaken the ethnic identity of the indigenous peoples of Central Siberia. In present time are developed and strengthened social stratum "national elites", which are characterized by symbolic ethnicity. For modern ethnicity processes of Indigenous Peoples of Central Siberia are characterized by dual ethnic identity.

The article presents the results of many years' field research of small-numbered indigenous peoples of the North and Siberia, resident in the territory of Krasnoyarsk Region (the Russian Federation). At the present time small-numbered indigenous peoples of Krasnoyarsk Region (the Evenks, Enets, Chulyms, Nganasans, Nenets, Selkups, Kets, Dolgans) are exposed to serious influence of modernization and global transformations. Ethnogeny and culture genesis processes are not the same for these ethnocultural groups. Some post-Soviet cultural practices support formation of a positive ethnocultural identity of indigenous peoples of the North and Siberia. Museumization of the Nganasan culture (an indigenous Siberian people resident only in Krasnoyarsk region) confirms the conclusion that Taymyr Neo-Shamanism is significantly different from the Shamanism of archaic and traditional cultures. Museumization of the Nganasan cultural heritage points out that the culture experiences a strong impact of modern market mechanisms. True Shamanism is no longer typical of the ethnocultural identity of the Nganasans.

Algorithms for solving linear PDEs implemented in modern computer algebra systems are usually limited to equations with two independent variables. In this paper, we propose a generalization of the theory of Laplace transformations to second-order partial differential operators in ℝ 3 (and, generally, ℝ n) with a principal symbol decomposable into the product of two linear (with respect to derivatives) factors. We con- sider two algorithms of generalized Laplace transformations and describe classes of operators in ℝ 3 to which these algorithms are applicable. We correct a mistake in [8] and show that Dini-type transformations are in fact generalized Laplace transformations for operators with coefficients in a skew (noncommutative) Ore field. © Pleiades Publishing, Ltd., 2012.

The fauna and rodent populations were studied in the forest belt of the Sayan and Kuznetski Alatau mountains. A comparative analysis of the composition and organization of their communities was conducted in 10 key sites located in different parts of the region. The differences in the communities were related to those in moisture conditions of their habitats. There were distinguished excessively wet (pergumid), wet (humid) and moderately moist (semihumid) sectors. The leading environmental factors affecting the rodent populations were the following: the eco-coenotic composition of subordinate forest layers, the composition and crown density of forest-forming species, heat and moisture characteristics, and anthropogenic transformation of the territory. Owing to variable effect of these factors on the rodent communities in different sections of the sites, information characteristics (diversity index) differ to a great extent.

We propose a generalization of Laplace transformations to the case of linear partial differential operators (LPDOs) of arbitrary order in Rn. Practically all previously proposed differential transformations of LPDOs are particular cases of this transformation (intertwining Laplace transformation, ILT). We give a practical procedure of construction of ILT and describe the classes of operators in Rn suitable for this transformation. © Springer-Verlag Berlin Heidelberg 2014.

The dynamics of shrews association in the mountain taiga of the Eastern Sayan was considered during the years 1981 to 2010. The work was carried out in the territory of "Stolby" reserve. The structure of the association, the duration of cyclic changes of different species, effect of succession and climatic processes on the composition and structure of the community have been studied. © 2012 Pleiades Publishing, Ltd.
