Estimation of the total inelasticity coefficient in interaction of greater than or equal to 20 TeV hadrons with lead

Experimental data on the interaction mean free path of hadrons with energy E 20 TeV in lead obtained with multilayer X-ray emulsion chambers(XEC) are compared with results of simulation of nuclear-electromagnetic cascades in lead chamber. It is shown that, to explain experimental data, the value of the inelasticity coefficients, K .8 should be assumed

Reconstruction of boundary controls in parabolic systems

In the paper, an inverse dynamic problem is considered. It consists in reconstructing a priori unknown boundary controls in dynamical systems described by boundary value problems for partial differential equations of parabolic type. The source information for solving the inverse problem is the results of approximate measurements of the states of the observed system's motion. The problem is solved in the static case; i. e., to solve it, we use all the measurement data accumulated during some specified observation interval. The problem under consideration is ill-posed. To solve it, we propose the Tikhonov method with a stabilizer containing the sum of the mean-square norm and total time variation of the control. The use of such nondifferentiable stabilizer allows us to obtain more precise results than the approximation of the desired control in the Lebesgue spaces. In particular, this method provides the pointwise and piecewise uniform convergences of regularized approximations and makes possible the numerical reconstruction of the subtle structure of the desired control. In the paper, the subgradient projection method for obtaining a minimizing sequence for the Tikhonov functional is described and substantiated. Also, we demonstrate the two-stage finitedimensional approximation of the problem and present the results of numerical simulation. © 2013 Pleiades Publishing, Ltd

Degradation and Restoration of Superconducting Parameters of HTS Tapes under Mechanical Loads and Heat Treatment

As it is known, the current-carrying properties of HTS tapes are structurally sensitive parameters, and largely depend on the grain size, morphology, texture, presence of pinning centers and others. These structural parameters may be changed by shock loading actions. The report presents the results of research of varying intensity shock loads effects from 0.35 to 100 J/cm2 on the structure and characteristics of superconducting Bi-2223 tapes. A strong degradation of the critical current

The article is devoted to the problem of organizing independent work of students in a higher technical educational institution, held in Tyumen Industrial University of the Nizhnevartovsk branch. This paper analyzes the requirements for students to master the skills of independent work on the basis of the competency model of a university graduate in accordance with the requirements of the professional standard of higher education. The competence of a successful specialist in any dynamically developing industry is considered. The author made an analysis of the works of scientists, teachers, researchers, dealing with the problem of motivation and improving the efficiency of the organization of work activities of students. The tendency to steady interest of students in additional material related to the profile of the main direction of study in the form of problem situations is revealed. Three forms of organization of independent work are highlighted and described in detail: extracurricular, classroom, and creative in the form of NIRS (students' research work). Express questionnaires of students were conducted to measure the time spent on independent work, to identify students' claims for research skills, for the types of independent work that are most laborious for respondents, diagnosing time spent on extracurricular work per week. According to the results of the study, graphs were made and diagnostic diagrams were constructed. The conclusion is formulated.El artículo está dedicado al problema de organizar el trabajo independiente de los estudiantes en una institución de educación técnica superior, celebrada en la Universidad Industrial de Tyumen de la sucursal de Nizhnevartovsk.

"ENERGY APPROACH" FOR CALCULATING THE ECONOMIC VALUE OF BIORESOURCES OF THE HUNTING FARM "SVIYAZHSKOE"

O papel dos animais no ecossistema é determinado por uma ampla gama de fatores. Este é, antes de tudo, o número, a biomassa e a natureza da alimentação. Devido ao fato de que a taxa metabólica em diferentes grupos de animais não é a mesma, o indicador mais importante de sua importância no funcionamento do ecossistema é o fluxo de energia que passa pela comunidade (energia transformável). O artigo apresenta dados sobre o uso de energia transformável para avaliar os recursos de espécies terrestres de vertebrados nas condições da fazenda de caça "Sviyazhskoe. A abordagem implementada pode ser aplicada a diferentes territórios. Uma limitação fundamental pode ser apenas a ausência de dados sistemáticos sobre os registros de todos os grupos.The role of animals in the ecosystem is determined by a wide range of factors.

The article presents data on the use of transformable energy for assessing the resources of terrestrial vertebrate species in the conditions of the hunting farm "Sviyazhskoe.

Synanthropic flora of Kuzbass

The article presents the materials of studies of the adventive flora of the Kemerovo region. For the territory of the Kemerovo region, we identified 244 alien species belonging to 162 genera and 50 families. As a result of the increasing process of invasion of new species into the territory of the region, the need for constant monitoring of alien species for the degree of their naturalization, especially in natural cenoses, is urgent. The problem of synanthropic plant species is becoming increasingly important not only for economically developed territories, but also for the relatively preserved mountain regions of Kuzbass. As a result of the studies, it was found that the synanthropic fraction of the Kuzbass flora, consisting of adventive and apophyte species, accounts for about 18% of the total composition of the flora of vascular plants in the Kemerovo region (60 apophyte species, 244 – advent ones). The revealed heterogeneity in the chorological, ecological and biological terms of the species of the adventive fraction makes it possible to find suitable conditions in various types of ecotopes on the territory of the Kemerovo region. This type of work can serve as a basis for developing a strategy for the preservation of natural phytosystems of Kuzbas
