Authors: Zagorskaya M S , Abdurashytov S F 
Published: December 2021

Abstract
The species of the genus Mentha have been known since ancient times and have significant value in the pharmaceutical, cosmetic and food industries, as well as in medicine. For the widespread use of mint, including in a variety of breeding programs, and the preservation of genetic diversity, effective methods of maintaining cultivars and collection samples are required. Thanks to the development of biotechnological methods, in particular, the creation of slow-growing collections, are now actively used as an effective alternative to field collections. It is known that the cultivation of tissues and organs on artificial culture media can cause somaclonal variability. The purpose of this work is to study the effect of in vitro storage at 4-6°C without illumination after 3 and 4 in vitro conservation cycles on the genetic stability of three cultivars of mint Azhurnaya, Bergamotnaya and Zagrava using ISSR primers. 1 cycle: 1 year of in vitro conservation, microcutting and 2 subcultures of regrowth in a culture room. After conservation, the number of viable explants was 70.0-82.1%. Callus formation at the base of the shoots was not observed in any of the cultivars. After 3 and 4 cycles of in vitro conservation, genetic stability was assessed using 11 ISSR primers. It was found that all three mint genotypes showed full compliance (length and number of amplicons) with the profiles of control samples for all studied markers. It was also found that the markers used by ISSR are highly informative for mint cultivars.

Monitoring of the condition and use of land in settlements (on the example of the city of Tchaikovsky, Perm Krai)
Authors: Simakova T , Simakov A 
Published: December 2021

Abstract
The paper presents a methodology for monitoring the lands of settlements, analyzes the state of the lands of the city of Tchaikovsky by qualitative and quantitative indicators, evaluates the assessment of the actual state of the lands of the city of Tchaikovsky, and develops a set of measures aimed at the rational use of the lands of the city of Tchaikovsky. The calculations carried out on the level of development and intensity of use of the territory over the past 10 years have allowed us to establish that, over the past 7 years, this indicator has hardly changed in the territory of the city of Tchaikovsky, only 1%. According to the results of a qualitative assessment of the state of the land, it was noted that the humus content in the soils is very low: no more than 3%, in heavy varieties, less than 2% - in light ones. Due to the small capacity of the humus horizon, it is completely involved in the arable layer, so it is reduced on the slopes as a result of water erosion. 35.5% of farmlands with a predominance of a weak degree of water erosion are subject to erosion processes. As a result of the assessment of damage from the manifestation of degradation processes, the amount of 60595 thousand rubles was established. As a result of the landscape and ecological zoning of the city territory, violations of the land use regimes within the boundaries of the established zones were established. Based on the comprehensive analysis, measures have been developed aimed at reducing the negative impact of enterprises and degradation processes. A set of measures to stabilize the state of the lands of the studied settlements is proposed.

Authors: Bykasova V , Kolodin K 
Published: December 2021

Abstract
The article reviews one of the types of ecological tourism – ecological settlement, its history, advantages and disadvantages. The domestic experience of ecological settlement engineering according to the criteria was analyzed, as well as the experience of existing settlements in the Baikal Natural Territory. The generally accepted scheme of ecological settlement arrangement cannot be implemented in its original form, since each site has its own features. Lake Baikal and its adjacent territories are UNESCO sites, have difficult climatic, geomorphological, landscape conditions, etc. The relevance of ecological settlement arrangement in this territory has been proved. As a result of the analyzes, a scheme of ecological settlement arrangement in the BNT was created. The results obtained allow us to conclude that it is possible to expand the field of research and search for new models. Cluster-based ecological settlements can serve as one of the directions for development. However, one of the most effective ways to check the results is the actual ecological settlement arrangement in the BNT with subsequent study during construction and operation.

Published: December 2021

Abstract
The gas transportation of Central Asian countries has been traditionally main part of their economic sector, because of geographical location and natural resources. Geographical and geopolitical Central Asia has significant commercial and political consequences across the region, and there gas production and export potential of the key Central Asia plays key role of gas transportation sector. Central Asian located in the centre of Eurasian continent and its transportation gas sector has very less implications in the global marketplace. Nowadays, geo-strategic role of this region is very low on global energy market. Central Asia is an important region of the Eurasian continent, touching Asia in the East and Europe in the West. The region is rich in oil, gas, gold, uranium ore and other underground minerals, and occupies an important geopolitical and strategic position, in which historically interests converged and intertwined diverse forces. This region surrounded by the giant powers Russia and China is still and strongly influenced by the unstable situation in the Middle East, Afghanistan, Pakistan and other adjacent regions. In addition, in the context of the expected increase in demand for energy resources in China, India and other Asian countries, reliable supplies of oil and natural gas from the Central Asian region contribute to the stabilization of the international energy market, in connection with which the importance of this region in terms of providing energy security.

Authors: Ambrosova Galina , Kruglikova Anastasiia 
Published: December 2021

Abstract
This scientific work is devoted to the results of the local treatment facilities’ work for food enterprises sewerage. The complex under consideration is intended for the anaerobic processing of whey, formed during fermented milk production. Whey is one of the specific organic substances, which main component is lactose (sucrose). It is converted under anaerobic conditions into lactic acid, which is a metabolic dead end. The capacity can be used as a homogenizing tank, obtained in this way. In the future, it is proposed to increase the homogenizer volume to 100 m3. It is recommended to use ammonium hydroxide or sulfate to ensure the required ratio between COD and biogenic element (nitrogen) in the loaded whey. Possible biogenic additives can be sewage sludge or slurry. The experience of adjustment was shown that slurry from cattle farms was quite simple, inexpensive and quite effective. Slurry can be injected in 3-4 m3 every 2-3 days. The stability of pH values in the bioreactor can be ensured by the correct placement of sensors for monitoring this indicator and by changing the method of alkali introduction. It is recommended to install pH control sensors at the bottom of the bioreactor, instead of whey loading pipeline. In order to provide for fractional injection of alkali, we should introduce part of the alkali at the homogenization stage, and part directly into the bioreactor. For an unimpeded build-up of anaerobic biomass, it is recommended to replace the centrifuge thickener operating with flocculant with the classic version of thickening in a compactor without flocculant adding.

Investigation of the possibilities of dewatering sewage sludge by the method of electroosmosis in order to prevent land littering
Authors: Kholudeneva A O 
Published: December 2021

Abstract
Wastewater sludge from industrial enterprises is disposed of at disposal sites. This leads to a negative impact on the soil cover. The well-known methods of dehydration of moisture-containing materials have been studied. The chemical composition of sewage sludge was investigated. A technical solution for reducing the volume of wastewater sludge formation is considered on the example of cardboard and paper production. An electroosmotic installation is proposed. To study the process of sludge dewatering, a series of experiments was carried out on the installation with variable parameters of the voltage between the electrodes. A model of the particle velocity in the medium under study was presented. It has been proven that with the help of an electroosmotic device, up to 70% of moisture is effectively removed from the volume of waste sludge waste. This makes it possible to significantly reduce their volumes, reduce areas for possible or temporary placement and reduce the environmental load on the environment.

Published: December 2021

Abstract
One of the areas of land management in territorial formations is the establishment of a special legal regime for their use. The main purpose of this research is precisely the comprehensive analysis of legal and social environment in order to create special-condition zones for the use of territories. Deductive, inductive, analytical, comparative legal and other scientific methods have been applied. This article identified a diversified nature that regulates the process of establishing zones under consideration and, besides, specifics of their parameters and restrictions to be imposed. The documentation setting out such parameters for each zone to be established was examined, and the interrelation between the features of the objects and the configuration of their protection zones was established. The greatest emphasis was placed on differentiating the conditions for the formation zones in two ways: in the process of integrated development of territories and in the creation of conditions for the protection of those sites that are already in use. As a result, it was revealed how the establishment of special-condition zones for the use of territories influences the content of urban planning documentation. In the first case, such a procedure is carried out during the planning phase of allocation of engineering and transport infrastructure. In the second case, zoning is carried out in order to bring the legal regime of previously commissioned infrastructure elements or natural and historical-cultural sites into compliance with current legal norms. However, in both cases there is an inextricable link to the territorial planning system.

Abstract
Among the many ways of representing and processing space information, polygonal ones are not so often found, although polygons, as geometric means of describing spatial information objects, are very common in wide internet content. In computer games, design, even in fine art and many other applications, the polygonal description of such objects is not only widely present, but also received from developers, both theory and practical implementation, a fairly wide set of mathematical and software tools. In this article, it is proposed to extend some well-proven developments in the analysis and transformation of computer images to real digitized satellite images, as well as to use combinations of satellite processing methods and polygonal methods which are characteristic for virtual reality conditions. In addition, the paper provides approaches for detecting hidden and being hidden artifacts – information bookmarks. The definitions of the main directions of intel-latency are given, as an important property of complex images of the Earth’s surface obtained during space monitoring of problem-oriented territories. A variant of the classification of the types of manifestation of this property is given, as well as its description in the language of soft models.

Published: December 2021

Abstract
Our article discusses the materials obtained by the authors in the study of the oxidation zone and primary ores of various deposits of the Kokpatassky ore field. The obtained research results confirm that the predominant part of gold remains in minerals replacing sulfides (pyrite, arsenopyrite) with the preservation of gold and its characteristic satellites in the oxidation products of sulfides (hedrogoethite, goethite and scorodite). Native gold belongs to fine and small size classes. The main concentrators of native gold are quartz, carbonate and oxidized forms of sulfides. Often, together with gold, arsenopyrite, scorodite, tetrahedrite, acanthite, electrums are noted.

Authors: Tangirov A , Ishboboev T , Urunov B 
Published: December 2021

Abstract
The leading role in the placement of gold mineralization in the Bukantau mountains belongs to structural and lithological factors. For gold-ore and gold-silver occurrences, sandy-shale strata of the flyschoid and olistostrome formations are favorable, then, rocks of the volcanogenic-dolomite-siliceous formation and then the carbonate formation (Okzhetpes type). The leading types of near-ore hydrothermal alteration of the host rocks in the studied deposits are silicification and, to a lesser extent, carbonatization and sericitization. They are accompanied by chloritization, biotitization, argillization, etc. Gold ore deposits and ore occurrences of sulfide-disseminated ores are confined mainly to the deposits of the Karashakh suite of the Middle Carboniferous (C2b + m1 kr). Moreover, gold-sulfide mineralization in the rocks of the Karashakh Formation is unevenly distributed.

Published: December 2021

Abstract
In this article, based on accounting, the interaction of the Earth’s crust blocks is limited by the deep breaks in the form of three-layer panels. The analysis dependences for tectonic pressure on elasticity parameters and the Earth’s crust layers capacity were obtained using the hypothesis of linear changes of deformations on the height of panels and the elasticity for bottom layers of the Earth’s crust. This paper considers the elastic interaction of crustal blocks bounded by deep faults in the form of three-layer panels. Using the hypothesis of linear measurement of deformations along with the height of the board and the elastic limit for the lower layer of the Earth’s crust, calculated dependences for tectonic stresses on the elasticity and thickness of the layers of the Earth’s crust are obtained.
Investigation of the width of the entry of an excavator when loading a mobile crushing plant in the conditions of the Angren coal mine of Uzbekistan
Authors: Bulatov G , Annakulov T 
Published: December 2021

Abstract
This article presents the results of studies to establish the optimal entry width for an excavator working in conjunction with mobile crushing plants in the development of overburden of the Angren open pit. According to the results of the research, an analytical relationship was established to determine the maximum productivity of the mining system “excavator-mobile crushing-reloading-conveyor complex” with cyclical-flow technology. A structural diagram has been developed that allows you to select the type and determine the main technological parameters of the equipment with the selected criteria for evaluating the effectiveness of the complexes. It has been established that the choice of equipment for conveyor lines should be carried out taking into account the mutual influence of adjacent technological links of the central heating systems, including the influence of the excavator-crushing and crushing-conveyor complexes on the efficiency of their mutual functioning within the framework of the adopted system as a whole. A functional graphical dependence of the excavator performance on the face width was obtained, taking into account the relationship of all technological parameters of the face. It has been established that the maximum excavator productivity of 1478.1 m3/hr is achieved with an excavator entry width of 17.4 m for the conditions of the Angren open pit. The resulting schedule makes it possible to assess the possibility of increasing the operational performance of single-bucket shovel excavators under various conditions of work, as well as to continue the optimization of excavation.

Abstract
The article is devoted to the study of steppe landscapes functioning of the Karadag nature reserve for the period of 6 years (2014-2019). The article uses a methodical approach to the assessment of intraday states of weather conditions to diagnose the nature of the steppe landscapes functioning. As results of the steppe landscapes functioning during the whole year the categories “development”, “destruction” both prerequisites and results of landscapes’ functioning, “accumulation” of prerequisites of landscapes development, and also mixed categories are distinguished. In general, the considered territory in the period from 2014 to 2019 is characterized by 85 variations of weather types. Considering of the steppe landscapes functioning in separate seasons, it is noted that, relatively alternating among them, in the winter period dominate the process of functioning prerequisites accumulation of steppe landscapes, and the process of prerequisites and results destruction of steppe landscapes functioning. The accumulation process is noted as the main result of steppe landscapes functioning in the spring season. It is dominant and fluctuates within 62.8 % and 96/8 % of the total number of functioning processes in steppe landscapes. The main result of functioning revealed in the summer season is development. It accounts for 63.2% (in 2014) to 99.9% (in 2015) of the diagnostic signs exhibited in steppe landscapes. In the autumn season the destruction process prevails, in a complex with parallel processes of various results of the steppe landscapes functioning.

Abstract
Development of territories from ancient times implied the presence of the most important component of life for all mankind: water. Man has always used the attractiveness of coastal living, which is associated not only with aesthetic perception, but also with production needs and quality standard of living. Thus, with the increase in human needs for water, the development of energy, transport, agricultural infrastructure, and the development of territories on the banks of rivers, lakes and seas increased. The creation of hydroelectric power plants became a powerful impetus in the development of energy in the XX century. Some of them were built as a result of the complex construction of a hydroelectric complex on flat rivers. After the creation of large reservoirs, the reformation of the shores invariably takes place. The city of Novosibirsk is the third largest city in Russia and it is quite natural that every year there is a population growth associated with the migration of residents from the nearby regions, Altai and Trans-Baikal Territories, and the northern regions of our country. The purpose of this work is to assess the current state of the banks of the Novosibirsk Reservoir and to predict shoreline reshaping. As a result of the work performed, data were obtained on the reformation of the coastline and the coastal destruction. The analysis was carried out at intervals of 50 years. The obtained materials are used and can be used to coordinate the placement of construction objects, allocation of land and preservation of land in the used territory, allotted for any type of use.
