Abstract
The task how to increase the industrial object crucial infrastructure reliability and safety is being studied formed with cyber-physical systems. To solve this task they represent a cyber-physical production as a complicated dynamic systems with tide and continuous conveyor cycles, which behavior is under control in the state parameters space. The cyber-physical systems actions of the inner technological environment factors and cyber-physical production external factors must be analyzed to study single and systematic actions of chaos creating character in equipment, which add some components to the control error. The emergency control is a directed cyber-physical action to maintain the cyber-physical production dynamic system in a non-variant state to the equipment failures and interferences. The control method and parameters are determined as a result of the assessment of the state of cyber-physical production performed in its phase space according to the predicted trajectories, probably indicating the dynamics of the technological environment and the risks of uncontrolled situations. The actual information of the cyber-physical production states includes the cyber-physical systems functionality modes data, which is proposed to be accumulated in a virtual environment to which the technological automatics of different hierarchy levels is connected to. The parametric states space dynamic system behavior trajectory forming principle is defined to make concrete separate cyber-physical systems and the cyber-physical production in general.

Published: October 2021

Abstract
The article presents the assessment methodology for anthropogenic water pollution in swimming pools, based on intelligent video monitoring of people physical activity, as well as a model for correlation data analysis and a regression model for the main parameters of chemical water contamination and doses of introduced reagents. The ultimate goal of the project is to create an intelligent water treatment management system for swimming pools. It is planned to use YOLOv4 neural networks to implement an intelligent pattern recognition module (swimmers in the pool) in the data stream coming from video cameras in real time. This innovative system will make it possible to automatically make managerial and technical decisions to determine the required amount of introduced reagents at various time intervals depending on the actual amount of organic contaminants, as well as other factors determined by the results of the correlation-regression analysis of the data. A review of information resources has shown that such a methodology does not exist both in Russia and abroad.

Published: October 2021

Abstract
The cyber-physical production industrial safety provision in emergencies is based on control technologies, which are applied in different combinations to prevent catastrophes. Emergencies are consequences of cyber-physical systems failures, which could lead to mass violations of equipment functionality modes and to a cascade distribution of failures through the entire cyber-physical production workshop. The techno-genic emergencies danger relates to construction and functional equipment violations completing technological operations with aggressive, explosive, highly flammable substances, which may penetrate out of the work chamber. Preventive measures reducing risks of safety accidents are address cyber-physical system control united in a conveyor line. The conveyor as a control object is regulated with actions produced with a virtual calculator based on control detectors data installed in cyber-physical systems and beyond them (in the technological environment). There is a scheme given how to control a cyber-physical production using the action dual mechanisms over the control objects.

Abstract
This article presents results of long-term monitoring of meadow biocenosis restoration after an oil spill and subsequent rehabilitation procedures at southern subtaiga territories of the Tyumen Region, Russia. The data obtained show that the measures taken fostered development of vegetation with high abundance and diversity of species. There passed 25 years after rehabilitation, and the succession stage of phytocoenosis at the affected area is not any more determined by pollution, but by bogging, a process characteristic of the unaffected biocenoses of the area under study. Secondary succession is also evidenced by more than a two-fold decrease in diversity and abundance of decomposer fungi species in a forest biocenosis adjacent to the area of oil spill. Such a decrease is conditioned by a reduced amount and variety of forest litter, that had been formed after the accident and was later humified by the fungi. In 2020, the ratio of the fungal species used as indicators of forest stand health prompted that the impacted forest was nearing its original condition. The terrestrial vertebrates communities have almost recovered over the period of monitoring, although there have appeared synanthropes, and the proportion of anthropophilic species has gone up.

Published: October 2021

Abstract
Chloroacetylation of a number of N- and C-alkenylanilines was studied and some further transformations of the obtained compounds were considered; the reaction proceeds most smoothly upon acylation with chloroacetyl chloride. By heating chloroacetanilides with an equimolar amount of pyridine in benzene, quaternary pyridinium salts were obtained in good yield. Some of the pyridinium salts have been shown to be highly effective as inhibitors of acid corrosion of steel. The interaction of chloroacetanilides with primary and secondary amines leads to hydrochloric ammonium salts, which are of interest as biologically active compounds.

Abstract
The article discusses topical problems of modern forest management regarding the procedure necessary to prescribe sanitation cuttings in dark coniferous stands damaged by the Siberian silk moth. Nowadays, the inability to timely cut down the defoliated, mature and overmature commercial dark coniferous timber leads to the formation of large areas of damaged stands that will hardly ever recover. There are no subsidies stimulating forest users to cut down forests damaged by the Siberian silk moth and conduct artificial reforestation. The present study suggests steps for adjusting the current legislation in pests control measures prescription in emergencies in forest land leased.
Improving the efficiency of separating machines equipped with flat oscillating sieves
Authors: Tkachev V , Borodin N , Knyazev A , Borovikov R , Lebedev V 
Published: October 2021

Abstract
The article deals with the separating machines equipped with flat sieves with various types of holes used for cleaning from impurities and sorting into fractions by size. It is noted that the main disadvantage of these machines is that in the process of their operation, the openings of the sieves are clogged by the separation products, which leads to a decrease in the separation efficiency, as well as a decrease in the productivity of the machines. It is mentioned that the most acute problem of cleaning the openings of sieves is when separating tree seeds. It is possible to increase the efficiency of the separating machines by using cleaning mechanisms that allow the seeds stuck in the holes to be pushed out when the machines are operating. A mechanism for cleaning the holes of sieves is proposed, equipped with cylindrical working bodies on which gears are mounted that are engaged with toothed rails. In the course of experimental studies on the treatment of tree seeds, the dependences of the completeness of the separation of the separated fraction on the specific load of the sieve, as well as on the speed of rotation of the drive shaft of the cleaning mechanism, were obtained. It is established that with an increase in the rotation frequency of the crank shaft of the cleaning mechanism, the completeness of the separation increases. It is determined that the greatest increase in the completeness of separation from 76.0% to 85.8% is observed when used in the design of the cleaning mechanism of gears with a diameter of 30 mm. It is established that the use of a mechanism for cleaning the holes of sieves, equipped with cylindrical working bodies, allows to increase the efficiency of the process of separating tree seeds.
Innovative grain seeder coulters
Authors: Zubarev A G , Laryushin N P , Kukharev O N 
Published: October 2021

Abstract
One of the main working bodies of grain seeders is the coulter, the work of which determines the uniform distribution of seeds along the length of the furrow and the depth of their seeding. Of the wide variety of used coulters, the most widespread are double-disc coulters, since they have less traction resistance and better quality indicators of their work. However, as shown by scientific research of foreign and domestic scientists, when the double-disc coulters are working, the quality indicators of their work are not met, as a result of which the yield of the cultivated crop decreases. To eliminate the noted drawbacks during the operation of double-disc coulters in the Penza State Agrarian University, innovative double-disc coulters for a grain seeder have been developed. During the operation of these coulters, in comparison with the serial ones, thanks to the installation of a seed guide, a soil ripper and a seed speed damper on the coulters, the seeds are evenly distributed along the length of the furrow and the depth of their planting.

Abstract
To increase the versatility of a class 1.4 tractor in a small farm, a universal hydraulic mounted system has been proposed, which allows the tractor to be used without changeover, both for agricultural technological operations, and for loading and construction works. The article discusses the use of mathematical modeling in the MathLab, Simulink environment and the steep ascent method to identify the optimal values of the mass on the rear axle and the stiffness of the tractor tires when driving on a horizontal supporting surface. When studying the dependence of the change in the control coefficient from two factors of variation: the mass on the rear axle and the stiffness of the tractor tires, the response function was obtained. By the method of steep ascent, the optimal design parameters of a tractor with attachments were determined, which make it possible to ensure sufficient controllability when driving on country roads.
Trends and prospects of technical support for separating beehive frames from the hive body
Authors: Voiku I P 
Published: October 2021

Abstract
Despite the active introduction of innovations, some types of routine work in apiaries continues to be done with considerable effort. The removal of the beehive frame is one such work. The frame separator consists of an upper plate, sidewalls containing protrusions, a through hole for an axis of rotation or a lower plate. The principle of operation of the proposed device is – when installing two devices on top of the upper plate of the beehive frame, each of the two shoulders of the frame is passed through the space formed by sidewalls and the lower plate, which interconnects them, or the axis of rotation, until the lower plate or the axis of rotation comes up against the outer contour of the side bar of the beehive frame. With devices installed on opposite parts of the upper bar, the beehive frame is placed in the hive body. The technical problem solved by the claimed invention is to ensure synchronous separation of the beehive frame from opposite sides of the hive body, reduce the user’s movements to remove the beehive frame from the hive to a minimum, reduce the probability of breaking the shoulders and the upper bar of the beehive frames.

Published: October 2021

Abstract
The use of alternative fuels derived from natural gas, coal, and renewable energy sources in tractor diesel engines (TDE) will solve the problem of replacing petroleum fuels, significantly expand the raw material base for obtaining motor fuels, and reduce the negative impact of motor vehicles on the environment. The use of alternative oxygenate fuels, such as ethanol (E), in diesel engines is particularly promising. As a result of the analysis of the conducted studies, it was found that it is possible to organize the working process in the cylinder of a TDE when it operates on E and rapeseed oil (RO), with their separate supply directly to the cylinders and ignition from the ignition fuel (pilot) with a high cetane number. As a starting fuel, it is possible to use RO, which is capable of self-ignition due to its physical and chemical properties. At the same time, it is expected to improve the performance of the working process, environmental and efficient performance of the TDE with the complete replacement of diesel fuel (DF).

AbstractTo analyze the positive influence of the technological module on the fluctuations of the external load of the tractor, the methods of statistical dynamics are used. A dynamic model of a process module with two rotating masses is considered: the rim and tire of the drive wheel and the translational mass of the process module. Using the transfer function, the spectral functions of the output process (the horizontal component of the force on the MTZ-82 tractor) were determined when performing a machine-tractor unit (MTA) technological operation with heavy disks (BDT-7) intended for a class 3 tractor. The developed mathematical model of the technological module allowed us to construct theoretical spectral densities of the horizontal component of the force on the tractor hitch when completing it with the technological module. The use of the process module allows the frequency range of forces on the tractor hitch to be shifted to a lower zone from 0 to 2.5 Hz, excluding high-frequency components compared to the standard configuration of the tractor.

ABSTRACT
Water containing ultrafine/nano bubbles (UFBs) promoted the growth of tomato (Solanum lycopersicum) in soil damaged by cultivation of tomato in the previous year or bacterial wilt-like disease and also promoted the growth of lettuce (Lactuca sativa) when lettuce was grown in the soil damaged by repeated cultivation of lettuce. On the other hand, UFB supply did not affect plant growth in rock wool or healthy soil. Furthermore, the growth of lettuce was not affected by UFB water treatment in the soil damaged by the cultivation of tomato. UFB water partly suppressed the growth of the pathogen of bacteria wilt disease, Ralstonia solanacearum in vitro. These data suggest that UFB water is effective to recover the plant growth from soil damage.

AbstractHow and where a female selects an area to settle and breed is of central importance in dispersal and population ecology as it governs range expansion and gene flow. Social structure and organization have been shown to influence settlement decisions, but its importance in the settlement of large, solitary mammals is largely unknown. We investigate how the identity of overlapping conspecifics on the landscape, acquired during the maternal care period, influences the selection of settlement home ranges in a non-territorial, solitary mammal using location data of 56 female brown bears (Ursus arctos). We used a resource selection function to determine whether females’ settlement behavior was influenced by the presence of their mother, related females, familiar females, and female population density. Hunting may remove mothers and result in socio-spatial changes before settlement. We compared overlap between settling females and their mother’s concurrent or most recent home ranges to examine the settling female’s response to the absence or presence of her mother on the landscape. We found that females selected settlement home ranges that overlapped their mother’s home range, familiar females, that is, those they had previously overlapped with, and areas with higher density than their natal ranges. However, they did not select areas overlapping related females. We also found that when mothers were removed from the landscape, female offspring selected settlement home ranges with greater overlap of their mother’s range, compared with mothers who were alive. Our results suggest that females are acquiring and using information about their social environment when making settlement decisions.
