Behaviour of the Blazar CTA 102 during two giant outbursts

Blazar CTA 102 underwent exceptional optical and high-energy outbursts in 2012 and 2016-2017. We analyze its behaviour during these events, focusing on polarimetry as a tool that allows us to trace changes in the physical conditions and geometric configuration of the emission source close to the central black hole. We also use Fermi gamma-ray data in conjunction with optical photometry in an effort to localize the origin of the outbursts.AST-1615796 - Boston Universit

Simultaneous spectrophotometric determination of chromium(VI) and iron (III) by H-point standard addition method

In this work the possibility of simultaneous spectrophotometric determination of chromium (VI) and iron (III) in alloys with help of the mixed organic reagent (diphenylcarbazide and 1,10-phenanthroline) is studied. We have applied Н-point standard addition method to determine concentrations of chromium (VI) and iron (III) from the mixture. The pure signals of complexes of chromium (VI) with diphenylcarbazide and iron (III) with the 1,10-phenanthroline and their calibration plots are previously carried out. We established the possibility of simultaneous determination of chromium (VI) and iron (III) in the different concentration ranges by Н-point standard addition method. Correctness of determination of concentration by means of the offered technique is proved by "added-found" method for a series of mixtures with different ratios of concentration of chromium (VI) and iron (III). It is founded that the error of determination of concentration doesn't exceed 33 %.

Learning analytics in massive open online courses as a tool for predicting learner performance

Learning analytics in MOOCs can be used to predict learner performance, which is critical as higher education is moving towards adaptive learning. Interdisciplinary methods used in the article allow for interpreting empirical qualitative data on performance in specific types of course assignments to predict learner performance and improve the quality of MOOCs. Learning analytics results make it possible to take the most from the data regarding the ways learners engage with information and their level of skills at entry. The article presents the results of applying the proposed learning analytics algorithm to analyze learner performance in specific MOOCs developed by Ural Federal University and offered through the National Open Education Platform. © 2018, National Research University Higher School of Economics.This study was support- ed by financial assis- tance provided under the Resolution of the Government of the Rus sian Federation No. 211, Contract No. 02.

Risk Assessment at the Cosmetic Product Manufacturer by Expert Judgment Method

A case study was performed in a cosmetic product manufacturer. We have identified the main risk factors of occupational accidents and their causes. Risk of accidents is assessed by the expert judgment method. Event tree for the most probable accident is built and recommendations on improvement of occupational health and safety protection system at the cosmetic product manufacturer are developed. The results of this paper can be used to develop actions to improve the occupational safety and health system in the chemical industry

Personalized patterns of teachers training in document science course subjects in a vocational pedagogical university

The article is focused on the study of challenging issues which occur when updating methodological-pedagogical support and applying personalized educational paths in the training of future teachers of document science course subjects for intermediate vocational education institutions, as well as according to various other programmes of students training as part of the "Vocational training (by branches)" course. The key method of the given problem research is meant to be analysis and experience summarization of vocational-oriented, academic, teaching and guiding and scientific work with the students of Russian State Vocational Pedagogical University, being taught according to principal educational programme "Document management in an organization" as part of "Vocational training (by branches)" preparation as well as learning methodological approaches for creating personalized educational paths for them. Research results: developed approaches to applying personalized educational paths in the training of students in a vocational pedagogical university; drawn-up recommendations on updating methodological-pedagogical support in the training of future teachers of document science course subjects for intermediate vocational education institutions, undertaken analysis of the possible ways of improving their training. The content of the article may prove helpful for: university faculty and universities chief executives for the improvement of the training quality of future professionals, for more effective educational process organization, for forming personalized educational paths in the training of students; for chief executives of intermediate vocational education institutions where the specialized training "Document support of management and archive science" is provided; for students being trained as part of "Vocational training (by branches)" course. © Authors

Hole-hole interaction in a strained Inx_xGa1−x_{1-x}As two dimensional system

The interaction correction to the conductivity of 2D hole gas in strained GaAs/In$_x$Ga$_{1-x}$As/GaAs quantum well structures was studied. It is shown that the Zeeman splitting, spin relaxation and ballistic contribution should be taking into account for reliable determination of the Fermi-liquid constant $F_0^\sigma$. The proper consideration of these effects allows us to describe both th temperature and magnetic field dependences of the conductivity and find the value of $F_0^\sigma$.Comment: 7 pages, 6 figure

PECULIAR FEATURES OF TEACHING HISTORY TO ECONOMIST STUDENTS IN RUSSIAN UNIVERSITIES

The purpose of the article: The article is aimed at studying of key issues of the set of methods and methodology of teaching history to students of the direction "Economics"; identifying of key aspects of the history course, competent understanding whereof is important for development of professional competencies of future economists, is of special attention.Materials and methods: The leading approach to the study of this problem is the analysis of key problem issues of the history course, a competent understanding of which is important for the formation of professional competencies of economists.Results of the research: The article shows that in the history of economics there are a lot of controversial, controversial issues on which quite superficial, subjective judgments and conclusions can occur in the journalistic, and sometimes academic literature. A number of similar questions are considered, the features of their study with students are revealed. The work identifies key aspects of the course of history, a competent understanding of which is important for the formation of professional competencies of future economists. The recommendations of the methodological and methodological plan for their study are proposed to increase the effectiveness of training future economists. Applications: This research can be used for the universities, teachers, and students. Novelty/Originality: In this research, the model of peculiar features of teaching history to economist students in Russian universities is presented in a comprehensive and complete manner
