The External Economic Factor in the Development of Northwestern Regions: Institutional Support and an Impact Assessment
This research is warranted, since the Northwestern Federal District accounts for a significant proportion of Russia’s exports. The study aims to reveal the connection between the federal district’s external and internal economic development and to identify the extent to which institutional support for international economic cooperation facilitates brisk international trade. The authors consider international trade from the perspective of its procedural and institutional components. The study stresses dependence between the total international trade and internal economic performance of Russia’s North-West. Another focus is an analysis of institutional support for the development factors and the levels and areas of international economic cooperation. The analysis shows that the Northwestern regions’ external and internal economic development is interdependent and there is considerable support for international cooperation at different levels and in different areas. To a degree, this is explained by the federal district’s geographical position and transport connections, the ‘Nordic’ character of the economy shared by the Russian and neighbouring territories, and the multi-tier nature of the institutional framework for international economic cooperation in the international region
Scientific Communication 2.0: Features of Presenting Scientific Content on German Popular Science YouTube Channels
The article is devoted to the feature’s analysis of the presentation of scientific content on the German-language popular science YouTube channels maiLab and Terra X Lesch & Co. It has been established that, in general, the popular science YouTube channels maiLab and Terra X Lesch & Co. are oriented towards the strategies and forms of presentation of scientific content adopted in the field of science: types of thematic progression characteristic of theoretical discourse (descriptive, explicative and argumentative) are used, as well as scheme of an argumentative statement. It is shown that, in contrast to the objectification mechanism of information exchange, which determines the presentation of scientific content within the scientific community, a personalization mechanism operates in the network of popular science communication, which is determined by the peculiarities of the interaction of the participants in network communication and the polymodality of the Internet as a medium. The authors consider in detail the techniques of intimization, emotionalization, dialogization, metaphorization, visualization and implementation of a narrative pattern. It is noted that these techniques allow bloggers to maintain the attention and interest of their channel subscribers, as well as simplify the presentation of scientific content, making it easier to understand. It is proved that the use of the strategy of personalization of information exchange, which is characteristic of mass media discourse, leads to a consistent violation of the prohibitions existing in theoretical discourse on any explicit manifestation of the subject of speech in a statement. The analysis of the material allows the authors to conclude about the active interaction of different discourses — theoretical and mass media — in their peripheral zones and describe the mechanisms of this interaction
Double-spiral magnetic structure of the Fe/Cr multilayer revealed by nuclear resonance scattering
We have studied the magnetization depth profiles in a [57Fe(dFe)/Cr(dCr)]x30
multilayer with ultrathin Fe layers and nominal thickness of the chromium
spacers dCr 2.0 nm using nuclear resonance scattering of synchrotron radiation.
The presence of a broad pure-magnetic half-order (1/2) Bragg reflection has
been detected at zero external field. The joint fit of the reflectivity curves
and Mossbauer spectra of reflectivity measured near the critical angle and at
the "magnetic" peak reveals that the magnetic structure of the multilayer is
formed by two spirals, one in the odd and another one in the even iron layers,
with the opposite signs of rotation. The double-spiral structure starts from
the surface with the almost antiferromagnetic alignment of the adjacent Fe
layers. The rotation of the two spirals leads to nearly ferromagnetic alignment
of the two magnetic subsystems at some depth, where the sudden turn of the
magnetic vectors by ~180 deg (spin-flop) appears, and both spirals start to
rotate in opposite directions. The observation of this unusual double-spiral
magnetic structure suggests that the unique properties of giant
magneto-resistance devices can be further tailored using ultrathin magnetic
layers.Comment: 9 pages, 3 figure
Clustering in light nuclei in fragmentation above 1 A GeV
The relativistic invariant approach is applied to analyzing the 3.3 A GeV
Ne fragmentation in a nuclear track emulsion. New results on few-body
dissociations have been obtained from the emulsion exposures to 2.1 A GeV
N and 1.2 A GeV Be nuclei. It can be asserted that the use of the
invariant approach is an effective means of obtaining conclusions about the
behavior of systems involving a few He nuclei at a relative energy close to 1
MeV per nucleon. The first observations of fragmentation of 1.2 A GeV B
and C nuclei in emulsion are described. The presented results allow one
to justify the development of few-body aspects of nuclear astrophysics.Comment: 7 pages, 8 figures, 3 tables, Nuclear Physics in Astrophysics-2,

Arquivar atividades em termos de autenticidade de documentos eletrônicos e variação do número de cópias
The article is devoted to the problems of archive activity during the digital era, which are conditioned from the authors' point of view by the introduction of electronic documents that have changed the content of paperwork and archiving key categories - authenticity and copy number variation, as well as related originality and authenticity. The technologies of work in the archive, always considered as a unique system of originals are based on the traditional understanding of these categories. Using the method of expert assessments during the determination of key category content, the authors conclude that the current activity of the archives is aimed at copy production activity increase, their management and the provision of authenticity, reliability, integrity and suitability for use. Nowadays the issue of document archiving requires the consolidation of state and non-state structure efforts to develop a new attitude to the authenticity of electronic documents, to change the usual nature of archival institution interaction with users and interested citizens, state authorities and administration, law enforcement and judicial system.El artículo está dedicado a los problemas de la actividad de archivo durante la era digital, que están condicionados desde el punto de vista de los autores por la introducción de documentos electrónicos que han cambiado el contenido del papeleo y las categorías clave de archivo: autenticidad y variación del número de copias, como así como la originalidad y autenticidad relacionadas.

Feasibility of study magnetic proximity effects in bilayer "superconductor/ferromagnet" using waveguide-enhanced Polarized Neutron Reflectometry
A resonant enhancement of the neutron standing waves is proposed to use in
order to increase the magnetic neutron scattering from a
"superconductor/ferromagnet"(S/F) bilayer. The model calculations show that
usage of this effect allows to increase the magnetic scattering intensity by
factor of hundreds. Aspects related to the growth procedure (order of
deposition, roughness of the layers etc) as well as experimental conditions
(resolution, polarization of the neutron beam, background etc) are also
discussed.
Collected experimental data for the S/F heterostructure
Cu(32nm)/V(40nm)/Fe(1nm)/MgO confirmed the presence of a resonant 60-fold
amplification of the magnetic scattering.Comment: The manuscript of the article submitted to Crysstalography Reports.

Structures and orientational transitions in thin films of tilted hexatic smectics
We present detailed systematic studies of structural transformations in thin
liquid crystal films with the smectic-C to hexatic phase transition. For the
first time all possible structures reported in the literature are observed for
one material (5 O.6) at the variation of temperature and thickness. In unusual
modulated structures the equilibrium period of stripes is twice with respect to
the domain size. We interpret these patterns in the frame work of
phenomenological Landau type theory, as equilibrium phenomena produced by a
natural geometric frustration in a system having spontaneous splay distortion.Comment: 7 pages, 6 figure
