    The recently selected missions to Venus have opened a new era for the exploration of this planet. These missions will provide information about the chemistry of the atmosphere, the geomorphology, local-to-regional surface composition, and the rheology of the interior. One key scientific question to be addressed by these future missions is whether Venus remains volcanically active, and if so, how its volcanism is currently evolving. Hence, it is fundamental to analyze appropriate terrestrial analog sites for the study of possibly active volcanism on Venus. To this regard, we propose Mount Etna - one of the most active and monitored volcanoes on Earth - as a suitable terrestrial laboratory for remote and in-situ investigations to be performed by future missions to Venus. Being characterized by both effusive and explosive volcanic products, Mount Etna offers the opportunity to analyze multiple eruptive styles, both monitoring active volcanism and identifying the possible occurrence of pyroclastic activity on Venus. We directly compare Mount Etna with Idunn Mons, one of the most promising potentially active volcanoes of Venus. Despite the two structures show a different topography, they also show some interesting points of comparison, and in particular: a) comparable morpho-structural setting, since both volcanoes interact with a rift zone, and b) morphologically similar volcanic fields around both Mount Etna and Idunn Mons. Given its ease of access, we also propose Mount Etna as an analog site for laboratory spectroscopic studies to identify the signatures of unaltered volcanic deposits on Venus

    At present, the problems in one way or another related to the risk of involving young people in illegal activities are recognized as the most pressing. In addition, the issues of well-being of various environments of an individual’s existence are recognized by the expert community and require close consideration. The educational environment is a unity of psychological and pedagogical reality, the purpose of which is to solve educational problems in the presence of specially organized conditions; tasks aimed at socializing students; as well as tasks for the formation and development of the student’s personality. The solution to the listed tasks in the educational environment, along with its psychological and pedagogical support, can act as an alternative to the aggressive social environment which results in the growth of sociogenic diseases. In this regard, this paper presents an empirical research program developed by the authors aimed at studying the psychological and pedagogical security and safety of the educational environment as a factor in providing the national security of the Russian Federation. The paper presents the results of a theoretical and methodological analysis of the main factors and risk indicators of the safety of the educational environment (school baiting (bullying), delinquent behaviour among children and youth, suicidal behaviour of children and adolescents, the problem of psychoactive substances use, the problem of Internet addictions); the research methodology has been substantiated; methodological tools (psychodiagnostics tools, sociological and pedagogical methods, methods of mathematical statistics) have been chosen. In addition, the proposed results have been identified in the framework of the research program, which are designed to contribute to the problem of ensuring the psychological and pedagogical security and safety of the educational environment in educational institutions which is being solved by the world psychological science. © Faculty of Education.

    © 2020. iJET. All Rights Reserved. The aim of this study is to determine the opinions of university students about technology-supported education. In today’s era, technological tools are used in every sector of education. Today, when technologies are rapidly developing, the opinions of students studying at university institutions about technology are very important. As per the outcome of the research, it is important to know the opinions of working people in terms of competencies and attitude towards the technology. The research was carried out in the fall semester of the 2019-2020 academic year with 75 students studying at the Federal University of Kazan (Volga region), the Institute of Legislation and Comparative Law under the Government of the Russian Federation, Plekhanov Russian University of Economics and Sechenov University. As the case study method was adopted in the study, researcher prepared open-ended questions as a data collection tool. In this research, qualitative method was used. According to the results obtained from the research, it was concluded that they did not feel themselves competent in technology, they did not have enough equipment and their schools are not equipped for technology-supported education

    Solar‐Related Variations of the Cloud Top Circulation Above Aphrodite Terra From VMC/Venus Express Wind Fields

    International audienceWinds derived by a digital tracking technique from UV (365 nm) images captured by the Venus Monitoring Camera onboard the Venus Express spacecraft from 2006 through 2013 were used to study the atmospheric circulation at cloud top level (70±2 km). This data set allows variations of the wind speed with both latitude and longitude to be studied and establishes their correlation with surface topography as well as local time dependence. Both zonal and meridional wind components show some correlation with topography. The minimum zonal wind speed was found at noon above Ovda Regio (10° S, 93° E), the highest region of Aphrodite Terra, one of the largest highlands in the equatorial region. The area of slow zonal wind extends to at least 30° S and shifts in the direction of superrotation in the afternoon and with increasing latitude (poleward). The observed deceleration of cloud top wind was recently attributed to the interaction of the gravity (mountain) waves generated by Aphrodite Terra with the atmospheric circulation. The present study was performed for different local time over the mountainous longitudes. The deceleration pattern in the zonal wind field is mainly conserved within a few hours around noon. Systematic longitude shift is observed in the afternoon in the direction of the evening terminator. Another area of perturbation of both zonal and meridional wind components is observed in the equatorial region around LT=13‐14 h and may be explained by the solar tide
