Published: February 2022

Abstract
Transportation of passengers by city transport plays an important role in the transportation of urban residents in Russia. The preference for personal transport over public transport leads to congestion of highways, increases the time of movement around the city, both by personal and public transport, and causes environmental pollution. For the population to choose public transport, it is necessary to improve the quality of transport services, and first of all, the transport accessibility of urban passenger transport. The main types of urban transport and their scope have been identified. The data of a questionnaire sociological survey of more than 16 thousand city residents were analyzed, 11 bus routes (12% of all routes) were studied. The standards of transport services were established and the analysis of deviations of the actual values from the declared ones was carried out. Individual indicators of comfort, timeliness, regularity, information content, as well as satisfaction with the quality of transport services in general in the city districts were assessed. Recommendations for reforming the city’s passenger transport are presented.
Biodegradable Food Packaging: Benefits and Adverse Effects
Authors: Shershneva E G 
Published: February 2022

Abstract
The article considers the problem of transition to environmentally safe types of food packaging materials. Features of modern biodegradable food materials and evolutionary generations of packaging materials are explored. Based on literature review, the author identifies a new generation of biodegradable food packaging – smart bio-packaging, representatives of which can be considered materials that have both “green” properties and advanced consumer qualities. Examples of such innovative biodegradable packaging are given: films and containers with antiseptic properties, enriched with vitamins and edible. It is generalized that bio-plastic has acceptable organoleptic, mechanical and chemical properties and can be an alternative to synthetic polymers. At the same time, the analysis of biopolymer production from the resource position revealed adverse environmental, economic and anthropogenic effects. In this context, the author presents “Paradox of ecological ricochet”: a contradiction between positive properties of biodegradable food materials and problems of increasing environmental burden for obtaining biomass. It is concluded that eco-safety of bioplastics depends on such factors as composition of materials, production process and how these material is destroyed after use.

Published: February 2022

Abstract
The article discusses the global climate warming impact on the most important agro-climatic parameters of the southern half of the Russian Federation European part. It has been established that in recent years a stable zone of moisture deficiency, stretching as a strip from Bryansk to the border of the Chelyabinsk region with Kazakhstan, has formed. At the same time, the most stable moisture deficit in summer is observed in the Bryansk region. For 2014-2016 the amount of moisture deficit according to the Bryansk State Agrarian University meteorological station was 47%. Due to the increasing climate aridity, the Bryansk region is approaching in agroclimatic parameters to traditionally grain regions. The increase in the amount of active temperatures turns its territory into an agro-climatic analogue of the northwestern part of the United States Corn Belt. A significant warming of winter, as well as a reduction in stable snow cover period, increases the beef cattle breeding competitiveness. At the same time, the cultivation of berries, raspberries in particular, becomes impossible without artificial irrigation.
Phosphorites and Glauconites as Additional Reserves in the Development of Titanium-Zirconium Sands of the Centralnoye Deposit (Tambov Region of Russia)
Authors: Georgievskiy A F , Bugina V M 
Published: February 2022

Abstract
After the Soviet Union demise, Russia was plagued by severe titanium resource problems. The bulk of titanium concentrates is imported from Ukraine. But Russia has its own titanium resources not lesser than in leading countries of the world (China, Brazil, South Africa). Ores form both primary and alluvial deposits, including those located in economically developed regions. The better example is the ancient marine placer of the Centralnoye deposit in the Rasskazovsky district of the Tambov region. In addition to ilmenite, rutile and zircon, ore sands also include phosphates and glauconite. The deposit was discovered in the middle of the last century and, after geological prospecting, was classified as one of the ten largest world objects of placer titanium ores. Despite this, for many years the Centralnoye deposit remained abandoned, since by that time, in the Soviet Union in Ukraine, several mining plants were already operating, which satisfied the industry’s demand for titanium. Today Russia is in dire need of titanium raw materials and the question of the need to develop the deposit has been repeatedly raised. This topic is being discussed especially actively today since a decision has been made on the expediency of its development. However, in the modern market environment, the implementation of this decision is an extremely difficult task. Here, the factors that can reduce operating costs that can improve the economic performance of mining and processing of ore sands become important. These factors include mining and use of both phosphorites and glauconites contained in titanium-zirconium ores and in the “overburden” rocks. The article describes the technogenic waste (tailings) of titanium - zirconium ores. Their material, mineral and granulometric composition is considered, and the technological properties of phosphorites and glauconites are described in the article. On the basis of experimental data, it has been shown that the accumulated concentrates represent high-quality raw materials for the production of phosphate rock and effective phosphorus and potassium ameliorants.
Mineralogy and Geochemistry of Metal-Bearing Formations Associated with the Sikhote-Alin Ultrabasites (Primorye)
Authors: Molchanov V P 
Published: February 2022

Abstract
A new promising type of multimetal ores and placers, spatially and genetically associated with the intrusion of the ultrabasites of the Sikhote-Alin orogenic belt has been discovered. The features of mineralogy and geochemistry of ore-placer occurrences of gold-ilmenite and gold-antimonite ores belonging to the Ariadnoye massif of ultrabasic rocks have been studied. The composition of the major industrial (economic) minerals has been revealed, the complex of associated high-technology metals being determined. The obtained data confirm the participation of these ore bodies (motherlodes) in the formation of the placers. The occurrences of titanium mineralization were the suppliers of ilmenite, platinum, copper and mercury gold, as well as of associated strategic metals. The antimonite-quartz veins were another power supply source for the placers.

Published: February 2022

Abstract
The article presents the results of multi-year research on technogenic pollution of biosphere components with wastes of cassiterite-sulfide formation processing. The areas of mainly Far Eastern taiga and Priamurye-Primorye coniferous-broad-leaved forest in the Far Eastern Federal District (FEFD) of Russia have been withdrawn from the forest land fund for their development. As a result, large amounts of mining waste have been accumulated, with negative impact on forest ecosystems. In this regard, the aim of the study was to substantiate forestry measures for improving their efficiency by reclamation and phytomelioration of technogenically contaminated lands with toxic mineral processing waste to accumulate carbon stock. The analysis and systematization of the literature and patent search materials testify that the article is devoted to the actual problem of carbon stock accumulation within the impact boundaries of the technogenic system by reclamation and phytomelioration. These problemsr in the conditions of mining enterprises of the Far Eastern Federal District of Russia are poorly studied. It is shown that the mineral development by the mining enterprises closed in the last century led to the large-scale destruction of forest communities. Methods of reproduction of productivity of technogenic polluted lands using bioremediation which novelty was confirmed by Patents of the Russian Federation are developed. By means of their reclamation and phytomelioration an increase in forestry measures and accumulation of carbon stocks in the reclaimed lands was achieved by more than 2.5 times in comparison with the nonreclaimed lands.

Abstract
Formation of a modern comfortable environment in Russian cities has become one of the priority tasks of the state scale. Development of fundamentally new approaches to the organization of integrated landscaping of courtyards and inter-building spaces according to the principles of comfort and bio-positivity will improve the quality of life of the country’s urban population. However, there are a number of organizational and informational problems associated with the interaction of territorial bodies of state and municipal administration, the interests of the population and organizations performing these types of work. The paper proposes a methodology for choosing elements of the improvement of the territory of courtyards and inter-building spaces both for the existing development and for newly built territories, based on taking into account the optimal ratio of the parameters of a comfortable environment, taking into account the peculiarities of the urban planning situation, utilities, the morphotype of the building, the type of yard, its configuration squares.

Authors: Fomichev P A , Fomicheva E V 
Published: February 2022

Abstract
The use of traditional means of vibration isolation of ship power plants does not always give the desired effect, which predetermines the need to search for and use fundamentally new devices to improve the efficiency of vibration isolation of a ship engine. This can be achieved by installing active-passive vibration isolators in the elastic mounts of the engine, such as electromagnetic hydraulic vibration isolators (EHVO) for auxiliary engines and other marine equipment. Despite the seeming simplicity of the design and principle of operation, the calculation of EHVO is a rather complex problem, the solution of which is associated with a number of difficulties due to the specific features of electromagnetic devices, since their calculation is associated with a large number of factors and limitations. The known functions of time obtained by solving the equations were used to calculate the dynamic parameters of the EHVO: vibration energy, periodicity, overheating of the coils and efficiency

Motion Control Model and HUV Dynamics for Patrolling Sea Areas with Complex Bottom Topography
Authors: Kiselev L V , Kostenko V V , Medvedev A V 
Published: February 2022

Abstract
The Patrolling sea areas is one of the main tasks of the HUV when performing both typical search and survey works and a number of special-purpose works when servicing marine infrastructures [1]. The task of patrolling includes a purposeful choice of the route of the HUV with the search and examination of objects (targets), which implies the use of effective control under conditions of uncertainty in the environment and a correct dynamic model of movement, taking into account possible errors in the initial data. Particularly difficult is the task of realizing the spatial movement of the HUV near the bottom with a variable relief and the presence of significant obstacles along the route of movement. In the general case, it is required to provide equidistant movement relative to the bottom with safe overcoming of obstacles and minimization of traffic costs [2]. The solution to the problem depends on the effectiveness of the executive bodies (propulsion and steering complex) and obstacle detection equipment (echolocation systems for forward and downward vision). The control algorithm is based on multi-channel rangefinder information to obstacles and the angular orientation of the AUV relative to the bottom topography profile. The structural and hydrodynamic characteristics of the hybrid vehicle obtained in [3] are used in the model of the dynamics of the HUV. The report presents the results of research on the issues under consideration based on modeling dynamic processes using software tools Simulink Matlab, StateFlow Simulink and available experimental data.

Abstract
This article presents the results of the research into the crop yield and productivity of deer pastures in the Republic of Sakha (Yakutia). Currently, the policies aim to preserve and increase the headcount of local breeds of domesticated reindeer. Due to this, we researched the food resources of deer pastures in Anabarsky Ulus. Laboratory research and livestock analysis of the food resources of deer pastures were carried out at the clinical diagnostic research laboratory of the Arctic State Agrotechnological University. The analysis of soil was carried out at the laboratory of the Agricultural Service State Budget Company under the auspices of the Ministry of Agriculture of the Republic of Sakha (Yakutia). The authors prove that the crop yield of natural deer pastures reaches up to 41.3 dt/ha at the total power of 38.4 GJ/ha, 2891 fodder units, and 198 kg of raw protein. Day-long deer pasturing plays an important role in preserving pastures. This system stipulates that the herdsmen actively control the herd and change the pastures daily depending on the deer’s need in grazing and having rest and taking into account the weather conditions, as well as the availability and quality of fodder.

Published: February 2022

Abstract
The development and operation of gas and gas condensate fields in Western Siberia is associated with a number of serious problems associated with the aging of the fields. One of these problems is the formation of sand plugs at the bottom of the well, which leads to a halt in production and the need for repairs. To solve this problem, it is necessary to correctly calculate the optimal well flow rate, taking into account the filtration resistance and pressure losses along the wellbore. The construction of an adequate mathematical model of fluid filtration in the conditions of sand plug formation will make it possible to correctly regulate the flow rate of the well and avoid complications in its operation.

Abstract
Information-computing technologies are becoming a necessary tool in solving various kinds of problems related to research in the field of agriculture. Modern methodology also does not ignore soil science and ecology. Unified databases are being created on the most important physicochemical parameters characterizing soils. This leads to the emergence of more and more promising means of computing technologies. In particular, software systems that would make it possible not only to make long-term forecasts, but also to simulate various kinds of processes. As a result, there is a gradual transition to artificial intelligence. At the same time, very broad tasks are set before him. One of them is the enhancement of human capabilities. But at the same time, one should not forget that artificial intelligence can work effectively only if tasks are prescribed for it to be performed. He is able to study, analyze, collate a huge amount of data and use the knowledge gained to properly organize the environment.
