COMPUTER-AIDED DESIGN OF DRAWING MODES OF CORED WIRE IN A METAL SHEATH
Determination of the minimum number of passes while ensuring
continuity of the shell and the required density of the powder core of cored wire in
a metal sheath
Non-reciprocal light scattering by lattice of magnetic vortices
We report on experimental study of optical properties of two-dimensional
square lattice of triangle Co and CoFe nanoparticles with a vortex
magnetization distribution. We demonstrate that intensity of light scattered in
diffraction maxima depends on the vorticity of the particles magnetization and
it can be manipulated by applying an external magnetic field. The experimental
results can be understood in terms of phenomenological theory.Comment: 10 pages, 4 figure

The authors analyze how the university scientific conferences in library and information studies are being reflected on the Internet. The findings of the study conducted by authors draw the attention of professional community to the problem of representation of academic proceedings of the Russiaβs institutes of culture. These conferences are seen as a professional communication channel and a means to improve professional competences in the whole library and information industry. The authors analyze the problems of accessing the proceedings of scientific conferences held by the universities of culture, which are the essential component of the Russian library science advance. Through monitoring the www-sites of the universities of culture and studying the Internet resources in the area, the authors review the existing ways of distributing information and propose the options for presenting full-text science information to provide efficient information exchange in the library and information sphere. The resources being built with the open data technology, providing a multiaspect search and storage of information for repeated and free use, are proposed as a priority. The findings of the study evidence that for the moment, the complete representation of the research activities at the universities of culture is unavailable, and there is a need to apply the resources proposed by the authors.ΠΡΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡΠΎΠ²Π°Π½ΠΎ, ΠΊΠ°ΠΊ ΠΎΡΡΠ°ΠΆΠ°Π΅ΡΡΡ Π² ΠΈΠ½ΡΠ΅ΡΠ½Π΅ΡΠ΅ ΠΈΠ½ΡΠΎΡΠΌΠ°ΡΠΈΡ ΠΎ Π²ΡΠ·ΠΎΠ²ΡΠΊΠΈΡ

Considerable enhancement of the critical current in a superconducting film by magnetized magnetic strip
We show that a magnetic strip on top of a superconducting strip magnetized in
a specified direction may considerably enhance the critical current in the
sample. At fixed magnetization of the magnet we observed diode effect - the
value of the critical current depends on the direction of the transport
current. We explain these effects by a influence of the nonuniform magnetic
field induced by the magnet on the current distribution in the superconducting
strip. The experiment on a hybrid Nb/Co structure confirmed the predicted
variation of the critical current with a changing value of magnetization and
direction of the transport current.Comment: 6 pages, 7 figure
Dense Plasma Focus: physics and applications (radiation material science, single-shot disclosure of hidden illegal objects, radiation biology and medicine, etc.)
The paper presents some outcomes obtained during the year of 2013 of the activity in the frame of the International Atomic Energy Agency Co-ordinated research project "Investigations of Materials under High Repetition and Intense Fusion-Relevant Pulses". The main results are related to the effects created at the interaction of powerful pulses of different types of radiation (soft and hard X-rays, hot plasma and fast ion streams, neutrons, etc. generated in Dense Plasma Focus (DPF) facilities) with various materials including those that are counted as perspective ones for their use in future thermonuclear reactors. Besides we discuss phenomena observed at the irradiation of biological test objects. We examine possible applications of nanosecond powerful pulses of neutrons to the aims of nuclear medicine and for disclosure of hidden illegal objects. Special attention is devoted to discussions of a possibility to create extremely large and enormously diminutive DPF devices and probabilities of their use in energetics, medicine and modern electronics
Aluminum surface layer strengthening using intense pulsedbeam radiation of substrate film system
The paper presents formation of the substrate film system (Zr-Ti-Cu/Al) by electric arc spraying of cathode having the appropriate composition. It is shown that the intense beam radiation of the substrate film system is accompanied by formation of the multi-phase state, the microhardness of which exceeds the one of pure A7 aluminum by = 4.5 times
