Difficulties of succession pipeline in large industrial enterprises of Nizhny Tagil in studies of tendencies of competitiveness of higher technical education
There have been significant changes in the higher education system in Russia recently. The possibility to apply for post-secondary education to several universities according to the results of the Unified State Examination (USE) and the transition to the two-level structure of higher education have significantly changed the landscape of competitiveness not only between individual universities, but also between large cities, which have become centers of mass attraction of applicants and young specialists. The number of students studying federally funded has been decreasing over the years. As a result, regional universities suffer a shortage of applicants, while local industrial enterprises suffer a shortage of young qualified personnel. The described problems are fully demonstrated in the system of higher education and training of young engineering personnel for large industrial enterprises in Nizhny Tagil. The article reviews the results of the study on the motivational field of academic migration of young people from the Nizhny Tagil city, conducted in February-March 2020. © Published under licence by IOP Publishing Ltd

MASTER: The Mobile Astronomical System of Telescope-Robots
We present the first russian robot-telescope designed to make prompt
observations of gamma-ray bursts (http://observ.pereplet.ru). The telescopes
are near Moscow. The system of telescopes with prompt pointing rates connects
to the internet. The main parameters are the following: Richter-Slefogt system
telescope (355 mm, f/d=2.4); Richter-Slefogt system telescope (200mm, f/d=2.4);
Flugge system telescope (280mm, f/d=2.5); TV-camera with 20x40 degree
objective; Two CCD cameras (Pictor 416); One CCD Apogee Camera AP16E. The type
of mount is German with 8 grad/sec slew rate. MASTER images stars down to 19
magnitude in a 1 min exposure covering 6 square degrees.Comment: 3 pages, 2 figure

Combined MASS-DIMM instrument for atmospheric turbulence studies
Several site-testing programs and observatories currently use combined
MASS-DIMM instruments for monitoring parameters of optical turbulence. The
instrument is described here. After a short recall of the measured quantities
and operational principles, the optics and electronics of MASS-DIMM,
interfacing to telescopes and detectors, and operation are covered in some
detail. Particular attention is given to the correct measurement and control of
instrumental parameters to ensure valid and well-calibrated data, to the data
quality and filtering. Examples of MASS-DIMM data are given, followed by the
list of present and future applications.Comment: Accepted by MNRAS, 11 pages, 8 figure
Features of Structural and Phase Transformations in Mo–Si–B and Сr–Al–Si–B Systems During Self-Propagating High-Temperature Synthesis
This study is dedicated to investigation of the combustion mechanisms during the SHS of ceramic
materials in multicomponent Mo–Si–B and Cr–Al–Si–B systems. It is concluded that the following
processes are defined the SHS for Si-rich Mo–Si–B compositions: Si melting, its spreading over the surfaces
of the solid Mo and B particles, followed by B dissolution in the melt, and formation of intermediate Mo3Si phase film. The subsequent diffusion of Si into Mo results in the formation of MoSi2 grains and MoB phase forms due to the diffusion of Mo into B-rich melt. The formation of MoB phase for B-rich compositions
may occur via gas-phase mass transfer of MoO3 gaseous species to B particles and B2O2 to Mo particles. In
Cr–Al–Si–B system firstly, the Al–Si eutectic mixture undergoes contact melting followed by formation
of the reactionary surface as the eutectic melt spreads over the Cr and B particles surface. An increase in
Al content increases the proportion of the Al–Si eutectic melt. The dissolution of Cr particles in this melt
becomes the rate-limiting stage of the combustion process. The melt is saturated with these elements followed by crystallization of CrB and Cr(Si,Al)2 grains. In the Cr- and B-rich areas and low melt concentration, the formation of CrB may occur via gas-phase mass transfer of B2O2 gaseous species to Cr particles. Consecutive formation of chromium and molybdenum borides and silicides is established by means of dynamic X-ray diffraction analysis. Compact ceramic samples were produced using forced SHS pressing technique. Their structural investigations were conducted by XRD and SEM
