This technology allows you to perform measurements with high accuracy in various areas of production. At present, the use of satellite technology in geodesy is limited at quarries in Vietnam and is mainly used to create a control network in the “Static” observation mode. The use of satellite positioning technology using reference stations allows you to simplify and improve the efficiency of geodetic surveys in quarries. However, Vietnam currently does not have its own network of base stations. This article presents the possibility of using a foreign network of base stations to create a topographic plan for the Nuubeo quarry (Vietnam).","PeriodicalId":103378,"journal":{"name":"Proceedings of the International Symposium \"Engineering and Earth Sciences: Applied and Fundamental Research\" dedicated to the 85th anniversary of H.I.

It is shown that the sources of pollution of the regional environment form a complex technogenic system triggering the development of qualitatively new negative processes violating comfortable living conditions of the local population. The complexity and scientific uncertainty of environmental impacts caused the development of modern methods of analysis of environmental safety in the region. The purpose of experimental and theoretical study was to develop a rational complex of modeling procedures ensuring reliable forecast as a basis of efficient solution to manage regional environmental condition. The above purpose was achieved via joint use of such mathematical methods as the integrated system analysis, synthesis of alternatives, algorithmization of processes and generalization of experimental data.","PeriodicalId":103378,"journal":{"name":"Proceedings of the International Symposium \"Engineering and Earth Sciences: Applied and Fundamental Research\" dedicated to the 85th anniversary of H.I.

Innovation policy in the development of the road network is not a one-time campaign, but the very essence of the modernization of the republic's economy, therefore, innovation activity is impossible without the use of high production technologies and management of the economic complex, without the involvement of management personnel and production personnel of high qualification and moral qualities.","PeriodicalId":103378,"journal":{"name":"Proceedings of the International Symposium \"Engineering and Earth Sciences: Applied and Fundamental Research\" dedicated to the 85th anniversary of H.I.

A power function of time is proposed to describe the change in the radionuclide flux from the atmosphere. It was found that there is good compliance between observations and the results of calculations (the discrepancy is less than 30%) concerning the Black Sea Rim Current and the Western Cyclonic Gyre. The maximum differences occur in the areas of anticyclonic vortices. The Cs stock in the Black sea was estimated for the period from 1986 to 1991.

Physic-mechanical and tribological characteristics of PTFE based polymer composite materials containing 1–10 wt.% CF+1 wt.% UPTFE have been studied. Simultaneous introduction of carbon fibers and UPTFE in PTFE causes the deformation-strength characteristics to remain at the level of those of the polymer matrix regardless of the CF content. Increased content of carbon fibers in UPTFE increases the stress during compression and decreases the PCM density. Wear resistance increases up to 310 fold, and the coefficient of friction of polymer composites decreases by 17–19% compared to that of the initial polymer. The results of the study of polymer composites by XRD analysis and scanning electron microscopy are presented. Introduction of fillers in PTFE changes the supramolecular structure, which is followed by an increased degree of crystallinity. The developed materials are promising for use in friction units of machinery and equipment.","PeriodicalId":103378,"journal":{"name":"Proceedings of the International Symposium \"Engineering and Earth Sciences: Applied and Fundamental Research\" dedicated to the 85th anniversary of H.I.

The study of urban floras identifies directions, dynamics and nature of the anthropogenic transformation of phytobiota and is of interest due to biodiversity conservation and historical significance for understanding phlorogenesis. The purpose of our study is to identify features of the biomorphological structure of the flora of Grozny, reflecting the adaptive potential of its phytobiota. The object is to identify life forms of the vascular plants of Grozny. The work analyzes field data obtained during expeditionary studies of the local flora. The methodological basis is the classification of climamorph suggested by C. Raunkier and the linear system of life forms developed by V.N. Golubev. The modern flora of Grozny includes 737 species which belong to 392 genera, 92 families and 3 divisions of higher vascular plants. The results of the study on the biomorphological structure show the prevalence of hemicryptophytes (51.28%) and polycarpic herbs (52.1%) in the urban flora. There are a lot of plants forming rhizomes (95 species) which is typical of natural communities of middle latitudes. The flora is of mesophytic nature, retains zoning features. It is foreststeppe hemicryptophyte-terophytic and similar to the regional flora. There are no saprophytes and an insignificant share of hamefits. Synanthropization of the flora is due to the apophytic fraction and its adventitization.","PeriodicalId":103378,"journal":{"name":"Proceedings of the International Symposium \"Engineering and Earth Sciences: Applied and Fundamental Research\" dedicated to the 85th anniversary of H.I.

The basic composition of heat-resistant ceramsite concrete was used in the study. This composition included a ceramsite gravel of the Kizilyurt Ceramsite Plant as a large and small filler, as well as the composite binding composition of portland cement + impalpable ceramsite sand with the activation on a planetary mill Activator – 4M. The use of light heat-resistant concrete instead of single-piece refractory materials in kilns of various thermal units will allow decreasing the material consumption by 30-40% and reducing heat losses by 25-35%. [8]. The use of local construction materials allows increasing the efficiency of concrete in comparison with imported refractory materials. The composition of light heatresistant concrete with large and small fillers from ceramsite gravel of the Kizilyurt Ceramsite Plant and the activated composite binding agent based on the portland cement of the Buynaksk Cement Plant with impalpable ceramsite sand is developed for the study. The activation of a composite binding agent effectively increases the reaction capacity of a binding agent and reduces the water cement ratio, which improves the performance of concrete [1, 2, 10] due to the reduction of chemically unbound water in concrete. We believe that the preheating of a mixture prior to drying at a temperature of 105°C effectively affects the performance of concrete and reduces its destruction due to the presence of chemically unbound water. This reduces the number of microcracks in the structure of a concrete due to intensified hydration of the activated composite binding agent. The optimum mode of preheating and its influence on thermomechanical characteristics of concrete is defined.
