On the meteor trail spectra

Meteor radiation appears as a result of collisions between meteoroid atoms and air molecules. Depending on duration, this radiation is usually divided into the following types: radiation of the meteor head; radiation of a coma surrounding or immediately following the meteor head; radiation of a trail formed as a result of fragments lagging behind or by the afterglow; and radiation of a meteor train forming from a tail as a result of various chemical and dynamical processes. To investigate physical processes caused by each of the above types, it is necessary to obtain the corresponding experimental data. The physical processes of the radiation and the measurement of the experimental data is discussed

METHODOLOGICAL APPROACH TO CONDUCTING CORPORATE TECHNOLOGICAL FORESIGHT AND AN EXAMPLE OF ITS USE FOR A COMPANY IN THE OIL AND GAS SECTOR OF RUSSIA

A methodological approach for conducting a technological foresight at the corporate level has been proposed. A corporate foresight based on general methodological approaches used in world practice should take into account a number of additional factors imposed by the specifics of the industry and organization in order to obtain a list of priority technologies and technological directions relevant to the company’s activities. Methodological approach is based on the concept “Markets-Trends-Technologies”. Global markets research allows us to determine key problems and trends of society evolution in economic, social, political and other arears. The transition to the corporate level is carried out by identifying trends in the company’s industry. The methodology have described in detail the methods of attracting experts to assess the power of mutual influence of trends and technologies. The results of the assessment can be used for subsequent technological mapping in scientific and technical forecasting and strategic planning

Geographic Information System and Geoportal "River basins of the European Russia"

The geoinformation system (GIS) and Geoportal with open access "River basins of the European part of Russia" were introduced. The GIS includes the results of spatial analysis and modeling, in particular, the assessment of anthropogenic impact on river basins; estimates of water flow and precipitation; climatic, geomorphological and landscape zoning of the European part of Russi

The Uzbek National Tradition in the Pedagogical Practices of Adult Educators

Received 2 April 2020. Accepted 1 June 2020. Published online 9 July 2020.While Uzbekistan strives to preserve its traditional culture and values (for example, respect for elders), interest in modern teaching methods is growing incrementally. This study aims to investigate whether and to what extent the national context affects teaching methods, in particular the interactive methods, which Uzbek professors use for training the civil service talent pool. The study is based on focus groups and content and cluster analysis. The results show that although Uzbek professors acknowledge the importance of the national context, their adult students’ needs and their own pedagogical experience are paramount in their choice of interactive methods. We also found that professors are highly motivated to try new methods, despite the lack of adequate access to cutting-edge resources. Therefore, their professional development should be aimed at improving their teaching qualifications by introducing the latest global trends in instruction methods. Conventional methods have to be revised and complemented with modern ones. This will lead to mutual enrichment between unique and strong Uzbek national traditions in education and contemporary international trends

Navigated Pattern Laser System versus Single-Spot Laser System for Postoperative 360-Degree Laser Retinopexy

Purpose. To compare three 360°-laser retinopexy (LRP) approaches (using navigated pattern laser system, single-spot slit-lamp (SL) laser delivery, and single-spot indirect ophthalmoscope (IO) laser delivery) in regard to procedure duration, procedural pain score, technical difficulties, and the ability to achieve surgical goals. Material and Methods. Eighty-six rhegmatogenous retinal detachment patients (86 eyes) were included in this prospective randomized study. The mean procedural time, procedural pain score (using 4-point Verbal Rating Scale), number of laser burns, and achievement of the surgical goals were compared between three groups (pattern LRP (Navilas® laser system), 36 patients; SL-LRP, 28 patients; and IO-LRP, 22 patients). Results. In the pattern LRP group, the amount of time needed for LRP and pain level were statistically significantly lower, whereas the number of applied laser burns was higher compared to those in the SL-LRP group and in the IO-LRP group. In the pattern LRP, SL-LRP, and IO-LRP groups, surgical goals were fully achieved in 28 (77.8%), 17 (60.7%), and 13 patients (59.1%), respectively (p>0.05). Conclusion. The navigated pattern approach allows improving the treatment time and pain in postoperative 360° LRP. Moreover, 360° pattern LRP is at least as effective in achieving the surgical goal as the conventional (slit-lamp or indirect ophthalmoscope) approaches with a single-spot laser

An improved adsorption method for the characterization of water-based supercapacitor electrodes

The specific surface area is a key characteristic of carbon materials used in supercapacitor electrodes. In this paper, the use of a methylene blue technique for specific surface area determination is presented. Values for the specific surface area, determined by a new method, provide better correlation with theoretical values for the specific electrical capacity of highly-porous carbon electrodes than the values measured by the common BET method. Additionally, the methylene blue adsorption method is thought to characterize carbon adsorption activity in relation to a supercapacitor electrolyte

Weakly-nonlocal Symplectic Structures, Whitham method, and weakly-nonlocal Symplectic Structures of Hydrodynamic Type

We consider the special type of the field-theoretical Symplectic structures called weakly nonlocal. The structures of this type are in particular very common for the integrable systems like KdV or NLS. We introduce here the special class of the weakly nonlocal Symplectic structures which we call the weakly nonlocal Symplectic structures of Hydrodynamic Type. We investigate then the connection of such structures with the Whitham averaging method and propose the procedure of "averaging" of the weakly nonlocal Symplectic structures. The averaging procedure gives the weakly nonlocal Symplectic Structure of Hydrodynamic Type for the corresponding Whitham system. The procedure gives also the "action variables" corresponding to the wave numbers of $m$-phase solutions of initial system which give the additional conservation laws for the Whitham system.Comment: 64 pages, Late
