Authors: Demina E N , Simonenkova A P , Luneva O N 
Published: March 2021

Abstract
Today, the production of innovative dairy products using various technological methods that improve quality is steadily growing. The formulation of such products includes various food additives, physiologically functional ingredients, plant materials, etc. Therefore, special requirements are imposed on the safety and quality of such products. The sanitary and epidemic quality of innovative dairy products is determined by the presence of pathogenic and other microorganisms in them. Development of technology for the production of innovative dairy products is usually concentrated in research laboratories. In this regard, close attention should be paid to the organization of measures aimed at creating an appropriate sanitary regime for the production of products of guaranteed quality. Such measures include careful monitoring of the content of microorganisms in the air, on laboratory equipment, utensils and utensils, work clothes and hands of laboratory staff, on the basis of which the sanitary and hygienic state of the production of innovative dairy products is assessed.

Authors: Abrosimova K S , Abrosimova N A , Morozova M A 
Published: March 2021

Abstract
Results are presented of studies on changes in the amount of hydroperoxides (malondialdehyde, diene conjugates and Schiff base) and A, C and α-tocopherol vitamins in the liver of two-year-old carp with aeromonosis in the initial and chronic stages from the farm ponds. An increase in the activity of lipid peroxidation from the onset of the disease to its chronic form has been borne out by a consistent increase in hydroperoxides and a decrease in the activity of vitamins A, C and α-tocopherol being the natural antioxidants of the fish organism. The opinion was expressed that the study of energy losses unauthorized by the fish organism will help optimize the treatment of carp aeromonosis and preserve the nutritional value of fish meat.

Published: March 2021

Abstract
Influence of existing conditions of operational work on terms of delivery of cargoes and observance of car turnover standards is investigated. Presence of considerable discrepancies between planned (standard) and actual indicators of car turnover periods and terms of cargo deliveries is accepted as the evidence of discrepancy of the accepted rationing system with the processes, which actually occur in system of railway cargo transportation of Ukraine. The basic principles of construction of the rationing system of railway cargo transportations, adequate to the actual state of the railway, are offered. The possibility of constructing such a rationing system is demonstrated on the example of data of the Ukrzaliznytsia information system about the time of cars’ turnover, which are to be unloaded at port stations with subsequent loading on the railways. It is shown that the requirements for the adequacy, ability to locate the problem link, adaptability, stability and safety of the rationing system are met by the use of ordinal statistics of the respective transport subsystem.

Published: March 2021

Abstract
One of the ways to save fuel for a road transport enterprises is to improve the regulation of consumption when using trucks in various operating conditions. In this review, domestic and foreign studies of factors affecting fuel consumption were considered. The review of studies shows that several factors are affecting the fuel consumption of vehicles in real operating conditions, which are not taken into account by the current Russian standards for the consumption of fuels and lubricants for road transport. Also, factors such as the rate of fuel consumption for freight turnover and the age of the vehicles need to be clarified. A review of studies has shown that the existing rates of fuel consumption for transport work do not meet modern requirements and additional accounting or clarification of the influence of such factors as the total mass of vehicles, the utilization rate of the carrying capacity, the age of the rolling stock and the technical speed is necessary.
Studying the Impact of Heavy Metals on the Composition of the Food and Processing Industry Wastewater in the Republic of North Ossetia-Alania
Authors: Biragova N F , Tinikashvili N A , Dmitrieva T V 
Published: March 2021

Abstract
The intensive development of industry, the growth of cities and other settlements, and their improvement require solving the issue of preventing the negative impact of human activities on the environment. This particularly concerns the food and processing sectors, which are among the strategic pillars designed to ensure a sustainable provision of the population with the high-quality food required. Water resources rank first by the intensity of the negative impact of food and processing industry on the environment. To eliminate or reduce the damage caused to the environment by industrial waste emissions, it is proposed to switch them to closed cycles. This would allow not only solving the environmental protection issue but also rationally using natural resources.
Wastewater contains feed residues, cooking salt, detergents, nitrites, phosphates, alkalis, acids, and possibly, pathogenic microflora.
The paper describes a rational technology developed for the neutralization and deep purification of agricultural wastewater.
Bilateral Asymmetry and Shape of Lamina Plantago major L
Authors: Baranov S G , Zykov I E , Biryukova T S , Fedorova L V 
Published: March 2021

Abstract
The aim of the work was to answer the question whether pollution by vehicles and the geographical location of populations affect the asymmetry and shape of the leaf plate Plantago major. The Generalized Procrustes Analysis was provided and the difference in the variance of paired landmarks was indicated. Based on vector coordinates, the symmetry and asymmetry covariance matrices of two types were created, and canonical covariance analysis was performed. The difference was found using the distances between the centers of the coordinate sets, the so-called Mahalanobis distances. The overall pool of leaves showed the presence of fluctuating asymmetry at the level of leaf blades in roadside populations. In the control, a mixture of two types of asymmetry: fluctuating and directional was traced. Canonical variation analysis showed the difference between the center of sets (p <0.0001). A correlation was obtained between the symmetric and asymmetric components of the shape. An allometric ratio of size/asymmetry and size/shape of the sheet plate were not obtained. The decrease in the number of landmarks from 52 to 26 did not affect the results. Thus motor transport, as shown by most of the samples (4 out of 6), had a significant impact on both the shape and asymmetry of the leaf blades. The geographical difference also affected both type of variability, as the difference in the asymmetry and shape of the plantain leaf blades increased over the geographical extent from Vladimir to Moscow on a distance about 200km.

Authors: Kalacheva L P , Ivanova I K , Portnyagin A S 
Published: March 2021

Abstract
In this work, the kinetic parameters and equilibrium conditions of the formation of natural gas hydrates in moist fresh and saline sand samples were studied by the method of differential thermal analysis. It was found that, in comparison with the systems "water-natural gas" and "sodium chloride solution-natural gas" in dispersed rocks, the equilibrium curves of hydrate formation are shifted to the region of high pressures and low temperatures. It is shown that the salinity of the pore solution leads to a decrease in the amount of absorbed gas and a decrease in the rate of hydrate formation.

Published: March 2021

Abstract
The reliability of operation of the main pumps is one of the most important in the pipeline transportation. In most cases, the failure of the unit is preceded by a sharp increase in the level of vibration. With a long service life of the pumping equipment, the frequency components of the vibration increase linearly and slowly enough with time, and then a strong increase in the oscillations begins, which ends in failure. The article is devoted to the analysis of the reasons for the high level of vibration of pipings, in particular during resonance with the disturbing frequency of main line pumps. The causes of vibration of pipings of the main line pumps and the influence of frequency regulation on the level of vibration of the main line pump are analyzed. Under the condition of frequency regulation of the operating modes of the pumping unit, the rotor speed can approach or coincide with the natural frequency of the straining vibrations.

Published: March 2021

Abstract
We studied corrosion fatigue cracks of operational origin in a steel gas pipeline and obtained a number of statistical data on their distribution on the metal surface.
This information is important for eddy current flaw detection of steel gas pipelines with stress-corrosion cracks. These data were used for making specimens of crack groups in special steel samples. Experimental studies of the signals of eddy current sensors over a group of cracks were carried out using these specimens.
Results of experimental studies of the signals of eddy current sensors of various types (absolute, differential) with different diameters of ferrite cores over specimens of crack group in special steel samples that are located at different intervals are presented. The research results show that the waveform of eddy current sensors undergoes significant transformation when changing the parameters of the group of continuity defects in the metal.
In the case of an absolute surface eddy current sensor additional local maxima signals, which are located over the center of continuity defects in a group of cracks, appear. In the case of differential surface eddy current sensor additional local extrema (maxima and minima) signals appear. These extrema are associated with the number and location of continuity defects in a group of cracks. It is shown that the waveform of the surface eddy current sensor over a group of cracks is determined by its type and parameters of a group of cracks in the metal. Mathematical conditions that make possible resolution or non-resolution of the signal of the surface eddy current sensor in the space of a group of cracks in the metal are found.
It is shown that when the defects in a group of cracks approach each other, a significant increase in the amplitude and half-width of the signal of the surface eddy current sensor occurs. The half-width of the signal of the surface eddy current sensor depends on the interval between the defects of continuity and their number in the group of cracks.

Authors: Kapelkina L P , Teplyakova T E 
Published: March 2021

AbstractThe structure and composition of the forming vegetation at the developed oil field in Western Siberia is considered. The absence of pathologies in plants in reclaimed and self-growing developed areas and the growth of Dactylorhiza maculata (a specially protected plant from the Khanty-Mansi AO Red Book) in the post-technogenic territory testify to the restoration of biodiversity and environmental safety of the emerging post-technogenic communities. Dactylorhiza baltica populations from the Red Book of the Russian Federation have been identified on the Russian Plain in the Leningrad and Yaroslavl Regions in the protected area of oil pipelines. In addition, in the Yaroslavl region, populations of Neottia nidus-avis, Platanthera bifolia, Glyceria lithuanica, Carex sylvatica, Dactylorhiza incarnata, Dactylorhiza maculata, Dactylorhiza fuchsii, Listera ovata, Ophioglossum vulgatum, Veratrum lobelianum, were found. These species are especially protected in the Yaroslavl region. The characteristics of their populations are given: the number of locations, the number of specimens, biotopes. The areas of various grassy biotopes in forest regions are increased through the length of treeless and protected spaces above oil pipelines. Thus these treeless spaces contribute to the conservation of rare and endangered edge-meadow, meadow and bog-meadow plants. Measures for the conservation and restoration of populations of specially protected species are recommended. A suggestion is made about the necessity to expand the assortment of sown plant species when carrying out reclamation work on post-technogenic lands using indigenous species for sowing seeds.

Published: March 2021

Abstract
The Russian Far East is a developing territory that is of a geopolitical importance for the country. A distinctive and significant role play the railroads that comprise 71% of total traffic. This explains a special attention of the state bodies to the railroad maintenance. The target of research is the roadbed deformation on some sections in the south of the Primorsky Region. The roads are built in complex engineering and geological conditions that suppose seasonal flooding and extreme weather conditions which produce some challenges for maintenance. The paper presents the results of field researches, current state data and surveys of hazardous road sections carried out by Far East State Transport University, Khabarovsk, Russia. Some consistent causes of deformation are determined, and the design and technological solutions as well as stability methods are offered for this region.
Suevites and Tagamites of Zhamanshin Astrobleme: Distribution in the Crater and Petrographic Features
Authors: Sergienko E S , Yanson S Yu , Kosterov A , Kharitonskii P V , Frolov A M 
Published: March 2021

Abstract
The study of impact glasses from the Zhamanshin meteorite crater has a long history extending back to early 1970ies. Most attention is paid to unique impact-related rocks known as zhamanshinites (bombs) and irghizites (lapilli). But, as first shown by V.L. Masaitis, other, more common types of impactites, suevites and massive melts (tagamites), are also present in Zhamanshin. We study the distribution in the crater, structure and composition of these particular rocks using powder X-ray diffraction and scanning electron microscopy. It is shown that all impact glasses from the Zhamanshin crater are genetically related and derive from the impact event, while the observed petrographic differences between them reflect the conditions of their formation. Individual varieties of studied impactites (suevites and tagamites) are spatially separated and, as a rule, do not intersect. This points to the absence of global mixing of the target material as a result of the impact event, as well as to the complex nature of the impactor.
Method of Autonomous Implementation of Manipulation Operations with Underwater Objects Having Predetermined Shape
Authors: Konoplin A Yu , Pyatavin P A 
Published: March 2021

Abstract
The report presents the stages of developing a new method for automatic underwater manipulation operations with pre-known objects. Based on the proposed method, a system builds on point clouds obtained from the onboard multibeam sonar of an autonomous uninhabited underwater robot identifies an underwater object with a known shape. To determine the location and spatial orientation of the specified object, a pre-built three-dimensional model of this object is used, and converted to a point cloud and subjected to additional processing. Then, by projecting the desired trajectory of the manipulator’s tool onto the object surface obtained during triangulation of the cloud points belonging to it, and evaluating the relative position of the real and desired trajectories, the system checks the accuracy of combining the point clouds of the constructed model and the real object being scanned. Based on the assessment, a decision is made to work out the trajectory built on the object’s surface by the manipulator. Even if the device has a low bandwidth communication channel with the operator, then the desired and real trajectories can be sent to the operator’s console for additional coordination of the possibility of performing a given manipulation operation. The proposed method is based on algorithms for combining point clouds, triangulation, and trajectory projection. The developed system is implemented in the C++ programming language using the open libraries PCL and Eigen. When performing numerical simulation of the system operation in the V-REP environment, we used a multi-beam sonar model, as well as scanned scenes that include objects of work. The project is built on the CMake system and uses "OpenGL Core" as a graphical shell.
Influence of the Speed of Motion of Public Motor Transport and the Time of the Green Signal of the Light Traffic on the Formation of Their Transport Flow
Authors: Averyanov Y I , Asfoor H M A , Golenyaev N S 
Published: March 2021

Abstract
The optimal traffic flow of public transport through a controlled intersection can be achieved by taking into account its speed and the time of the green traffic light. Regularities of the influence of the green traffic light period on the number of public transport passing through the intersection, the acceleration time of public transport on its speed, the green light duration on a distance that public transport can cover, and the distance covered by public transport on the passing time are revealed. The results of the study suggest that there are reserves for increasing traffic flow by controlling the high-speed mode of public transport and taking into account the operating time of a traffic light object.
Economic Benefits and Costs of Platform Solutions in the Modern Development of Natural Resources of the Russian Arctic
Authors: Pilyasov A N , Tsukerman V A 
Published: March 2021

Abstract
The article describes a new platform business model for the development of natural resources in the Arctic, which had emerged in recent decades and replaced the conveyor model of large industrial mining plants of the Soviet era. Using the example of new resource projects in the Russian Arctic, we analyze its main advantages associated with high adaptability, labor productivity, innovation, widespread use of artificial intelligence technologies, and the disadvantages associated with extraterritoriality and social alienation from the territory of presence. The role of the state in these conditions is analogous to the role that the branch trade unions had played in the industrial era: it is to protect labor over capital. We are talking about the formation of the state regulation of corporate social responsibility in the Arctic, about the use of the institution of social license for the company, which has proved its efficiencyabroad, partnership agreements with the municipal and regional authorities of the Arctic territories. Contemporary priorities of the public policy in the Arctic, which are aimed at raising the level of real incomes of its residents to the national average and helping to attract private investment in the Russian Arctic, do not in any way work to correct the imbalances between labor and capital arising in the platform business model.

Authors: Arslanova M M , Shornikova E A 
Published: March 2021

Abstract
An increase of technogenic load on the catchment area with a decrease of the volume of water protection measures leads to spread of surface water pollution. The paper considers the chemical composition of surface waters in Khanty-Mansi autonomous okrug – Ugra. The technique for analyzing the chemical composition of surface waters based on the combined application of the method of cluster analysis is presented. In this work, the concentration of metal ions in the rivers under study was determined. It was found that concentrations of iron and zinc ions exceeded the maximum permitted concentrations for fishery rivers (MPC) in 100% of samples, as for copper concentration an excess of MPC was noted in some cases. The spatial dynamics of the distribution of chlorides and oil hydrocarbons in surface waters is considered. According to the monitoring data, the analyzed surface water samples had very low concentrations of chlorides and oil hydrocarbons.

Published: March 2021

Abstract
The possibility of enriching the intestinal microbiota of cockroaches of the species Pycnoscelus nigra with a cellulolytic strain - Bacillus pumilus IB-320 was reviewed, as well as an assessment of the effect of the used microorganism on process of bioconversion of various types of paper waste and soil humification. Based on the results of a model experiment with a period of 90 days, various degree of bioconversion of cellulose-containing wastes for the zoomicrobial comple were found (in descending order): grass hay, paper and soil substrate (mix of brick crumbs, softwood sawdust and coconut-fiber substrate). Treatment with strain IB-320 contributed to an increase in the total number of bacteria obtained from the substrates and fecal extracts of cockroaches by 1.5-1.7 and 1.5-3 times, respectively. The introduction of the selected strain also significantly increased the rate of destruction of such substrates as cardboard and egg trays by 40% and 25%, accordingly. In the variant with using the grass hay, the presence of strain IB-320 led to an increase in humic acids by 1.5. The prospects of application Bacillus pumilus IB-320 as part of an active zoomicrobial complex for more efficient disposal of cellulose-containing waste have been shown.
