The problem of professional burnout in stress management

The problem of professional burnout is extremely relevant in current stress management. By its nature, professional burnout is a unique type of stress syndrome that is characterized by emotional exhaustion. It leads to loss of energy and interest in one’s job. A burnout could be the result of such syndromes as – burnout and boreout. It could emerge as the reaction of the organism to the high working intensity and stress working conditions or due to the boredom and absence of the sphere for professional realization. Both syndromes negatively influence the professional activity and require serious research and an adequate approach to the study. Studies have been conducted in the higher educational environment and among production employees. The studies were conducted with the application of the existing tests for revealing the “boreout” and “burnout” syndromes. Studies have shown that the syndrome “burnout” is common among workers with free working regulations, whose work requires greater independence, initiative and responsibility. According to the results of the study, the employees who are more free in the performance of their professional duties (teachers, managers) are less subjected to the boreout syndrome. For the prevention and control of professional burnout company management needs to apply the achievements of stress management

The policy of import substitution as the basis for economic security and well-being of society

The study presents the analysis of import substitution opportunities on separate branches of economic activity, preceding the realization of import substitution policy with the aim to support national economic security, which is essential for the contemporary society welfare insurance. Currently, social well-being is considered to be the reflection of economic activity, the instrument of state influence on the society, as well as an indicator of the social security system. Due to the fact that Russia is integrated into the world economy, the foreign-economic policy currently is playing an important role in the development of national security and the state's interest to the spheres of economy considering external and internal threats. Decline in external economic conditions may result in serious consequences for the functioning and development of the country as well as for the trade and investment activities, which will further lead to the decline in export, withdrawal of capital, recession of industrial production, trade and investment sphere, fall of GDP and living standards. Thus, considering the current state of instability in the world economy and the growing political tension in relation to Russian Federation, the measures to increase economic security in the country should be taken. The policy of import substitution is considered to be one of the major solutions nowadays

About the use of R-66 reagent in the technology of flotation enrichment of mixed copper

The paper presents laboratory and pilot flotation tests of the R-66 reagent on samples of mixed copper ore from the Konyrat deposit. The medium regulator reagent was supplied to the main flotation. Laboratory tests of the technology of flotation concentration on ore with a copper content of 0,31 % in a closed cycle in the optimal mode: R-66 - 100 g/t, sodium sulfide - 150 g/t, xanthate - 45 g/t, blowing agent - 60 g/t allows to extract copper into concentrate up to 85 %. At the same time, the copper content in the concentrate after two cleanings was reached at the level of 4,5 %, sulfur 42,3 %. At the same time, the R-66 reagent (100 g/t) makes it possible to completely eliminate the use of lime (1 000 g/t) in the ore dressing scheme

Mathematical models of viscosity diagrams and crystallization temperatures of melts of the CaO – SiO2 – Al2 O3 – B2 O3 system

Mathematical diagrams of viscosity and crystallization temperatures of melts of the CaO – SiO2 – Al2 O3 – B2 O3 system were created. To obtain them, experimental studies were carried out using the simplex-lattice method of experiment planning. It was used to study 35 slags containing (wt.%) 9.8-52 CaO, 33.6-70.4 SiO2, 16.0-51.52 Al2 O3, 0-20 B2O3. The experiments were carried out on an electrovibrational viscometer in molybdenum equipment, in a stream of purified argon in the temperature range of 1 473–1 923 K

Using radio astronomical receivers for molecular spectroscopic characterization in astrochemical laboratory simulations: A proof of concept

We present a proof of concept on the coupling of radio astronomical receivers and spectrometers with chemical reactorsand the performances of the resulting setup for spectroscopy and chemical simulations in laboratory astrophysics. Several experiments including cold plasma generation and UV photochemistry were performed in a 40\,cm long gas cell placed in the beam path of the Aries 40\,m radio telescope receivers operating in the 41-49 GHz frequency range interfaced with fast Fourier transform spectrometers providing 2 GHz bandwidth and 38 kHz resolution. The impedance matching of the cell windows has been studied using different materials. The choice of the material and its thickness was critical to obtain a sensitivity identical to that of standard radio astronomical observations. Spectroscopic signals arising from very low partial pressures of CH3OH, CH3CH2OH, HCOOH, OCS,CS, SO2 (<1E-03 mbar) were detected in a few seconds. Fast data acquisition was achieved allowing for kinetic measurements in fragmentation experiments using electron impact or UV irradiation. Time evolution of chemical reactions involving OCS, O2 and CS2 was also observed demonstrating that reactive species, such as CS, can be maintained with high abundance in the gas phase during these experiments.Comment: Accepted for publication in Astronomy and Astrophysics in September 21, 2017. 16 pages, 18 figure

On the application of surface enhanced Raman scattering to study the interaction of DsRed fluorescent proteins with silver nanoparticles embedded in thin silica layers

The interaction of proteins with silver nanoparticles (AgNPs) is of primary importance to uncover silver antimicrobial efficiency and environmental hazard. This interaction can affect silver reactivity, bioavailability and, eventually, silver toxicity towards the environmental media. Detection of the interaction of DsRed fluorescent proteins with AgNPs embedded in thin silica layers is demonstrated using surface enhanced Raman spectroscopy (SERS), but deep analyses require the design and elaboration of dedicated plasmonic substrates giving a high enhancement factor

Изучение цитокинов в крови больных туберкулезом, ассоциированным с вич-инфекцией

In the present work the data of comparative studying the cytokine status (serum concentration and spontaneous production IL-4, IFN-g, TNF-a) at HIV-infected and HIV-non infected persons with the active for the first time revealed tuberculosis, and also an establishment of possible interrelation between these parameters and amount of virus loading, level CD4+T-cell in blood of HIV- infecte patients from TB (group HIV/TB). In process of progressing associated HIV/ТВ infections and development of heavier forms of TB the increase serum content IFN-g and TNF-a testifying about displacement of balance aside increases proinflammatory cytokines on a background of decrease in number CD4+T-cell, increase of virus loading of a HIV is marked. The received results testify about immunosupreses with an exhaustion of functional reserves mononuclear cells of the peripheral blood aggravated in process of progressing of disease, being one of pathogenetic mechanisms of formation of secondary diseases, both virus, and the bacterial nature.В настоящей работе представлены данные сравнительного изучения цитокинового статуса (сывороточной концентрации и спонтанной продукции IL-4, IFN-g, TNF-a) у ВИЧ-инфицированных и ВИЧ-еинфицированных лиц с активным впервые выявленным туберкулезом, а также установление возможной зависимости между этими показателями и количеством вирусной нагрузки, уровнем CD4+T-лимфоцитов в крови ВИЧ-инфицированных больных с активным впервые выявленным туберкулезом (группа ВИЧ/ТВ). По мере прогрессирования ассоциированной ВИЧ/ТВ инфекции и развития более тяжелых форм туберкулеза отмечается увеличение сывороточного содержания IFN-g и TNF-a, свидетельствующее о смещении баланса в сторону увеличения провоспалительных цитокинов на фоне снижения числа CD4+T-лимфоцитов, нарастания вирусной нагрузки ВИЧ. Полученные результаты свидетельствуют об иммуносупрессии с истощением функциональных резервов мононуклеонарных клеток периферической крови, усугубляющейся по мере прогрессирования заболевания, являющейся одним из патогенетических механизмов формирования вторичных заболеваний как вирусной, так и бактериальной природы
