Authors: Gudkov A G , Pavlov M V , Karpov D F 
Published: March 2023

Abstract
The purpose of the article is to clarify and supplement the methodology given in the current regulatory and methodological framework for the purpose of engineering calculation of the storm flow management scheme for sewage treatment plants. The flow control scheme, including an intermediate tank, a pumping station and a separation chamber, is analyzed by mathematical modeling using a computer algebra system. Changes are proposed in the calculation formula for determining the volume of storage tank for the scheme of emptying the tank by pumps, taking into account all types of separation chambers. The dependence is established and graphs are shown showing the effect on the volume of the tank of the coefficient, which takes into account the variability of the flow diverted by the separation chamber into the collector.
Choice of method for determining the concentration and fractional composition of dust and gas flow

Published: March 2023

Abstract
The presence of industrial dust in concentrations exceeding the MPC leads to environmental pollution and threatens environmental safety. The article presents a method for determining the concentration and fractional composition of the dust and gas flow. The essence of the described method lies in the registration and analysis of vibroacoustic signals that occur due to vibrations of parts of the measuring system. The principle of operation of the system is based on the transmission of shock acts of oscillation generation along a chain that includes dust particles, a boundary layer, a dust pipeline wall, and, finally, a piezoceramic sensor of the system. The disperse composition of dust can be determined by two mathematical models (Fourier polynomials) - one reflects the energy spectrum, the other - the amplitude-phase. These polynomials are obtained by applying the Laplace transform to the signal and actually reveal the physical meaning of the process of formation of harmonics in the frequency subspectra. The processing of an acoustic signal on a computer by a fast discrete Fourier transform leads to an accurate description and calculation of the amplitude-frequency spectrum in real time. The main task is to isolate the frequency subspectra, consisting of the main and timbre harmonics for dust monofractions. The method of static moments is used to refine and form the frequency package of the main harmonics. The implementation of the method is carried out on a laboratory stand during the transfer of a dust-gas flow with pure monofractions and with a stepwise increase in concentration, the amplitudes of the main and timbre harmonics increase, which forms the frequency subspectrum of the analyzed dust monofraction. For further analysis and processing of AS spectra, a block diagram of an algorithm for determining the fractional composition of a moving dust and gas flow has been developed.
Hogweed Sosnowski as a useful plant for the production of bioethanol
Authors: Mezentsev Sergei Dmitrievich 
Published: March 2023

Abstract
The article explores the history of breeding hogweed Sosnovsky “Severyanin”, its cultivation for preparing silage and feeding cattle in the Soviet Union, the reasons for the refusal to grow it and its rapid spread in many regions of Russia, its capture of free spaces and the displacement of other plants. The scale of advancement of cow parsnip has become threatening in the European part of the country. As a result, it was deleted from the Russian State Register of Breeding Achievements and classified as a weed. The article emphasizes that an active fight against wild-growing hogweed is currently being carried out using various methods and means. But it does not give significant results. Since the measures taken to eradicate the hogweed turned out to be untenable, the question arises: what to do with Sosnowsky’s hogweed? The article proposes to solve this problem by cultivating it, mowing it and producing biofuel from it. The potential of hogweed as a useful plant is revealed, the technological scheme of its processing is given. The most important requirement is the creation of a closed, environmentally friendly production in order to prevent the uncontrolled spread of hogweed and protect people from skin burns caused by oils contained in it. The article formulates the tasks that consist in using Sosnowsky’s hogweed in solving the energy problem.

Authors: Solovitskiy A N 
Published: March 2023

Abstract
Geodynamic risks were studied during the development of coal deposits in the Russian Federation at the end of the last century, due to the difficulties in implementing green energy. The main directions of their development are established, their sectorial focus is noted, and a new methodological approach is proposed. Therefore, the purpose of the research is to develop a methodology for assessing the risk of geodynamic hazard of the earth’s crust block state in the areas of coal deposits’ development in the Russian Federation in order to ensure safety, which is a complex scientific task. The proposed risk assessment methodology includes an integrated approach taking into account geodynamic zoning, monitoring and industrial safety. The proposed risk assessment methodology includes a systematic approach, taking into account geodynamic zoning, monitoring and industrial safety. The practical use of the implementation of the proposed methodology is to expand the use of digital technologies for collecting information, as well as to gain new knowledge about the impact of geodynamic processes on safety and sustainable development of territories

Authors: Kambulov S I , Rykov V B , Bozhko I V , Podlesniy D S , Chikrizova V B , Ivanova T A 
Published: March 2023

Abstract
The article discusses the options of working bodies for tillage of steam fields in the summer. These studies are aimed at obtaining agrotechnical indicators of the technological process of tillage of steam fields. In particular, the design of the working body in the form of a flat one-sided paw is proposed. Laboratory and field studies were carried out to determine the qualitative indicators of the technological process of fine tillage, with all variants of working bodies. During the research, such indicators were established as: the optimal (recommended) speed of the unit, the depth of tillage by working bodies, the width of the unit (working), the average square deviation in the depth of processing and the width of the grip. The aggregate composition of the soil was assessed by fractions, the content of erosive-hazardous particles before and after the passage of the unit, pruning or destruction of weeds and the ridge of the field surface after the passage of the unit. Data on the dynamics of soil moisture after several treatments of steam fields with various variants of working bodies were obtained. As a result of the research, it was found that the working body in the form of a flat one-sided paw, in comparison with the working body of a serial steam cultivator, allows to reduce the depth of processing by 1.6 cm (up to 5.2 cm), to reduce the value of the combiness of the treated surface by 2.4-3.4 cm, while ensuring complete pruning of weeds both annual and perennial. The variants of working bodies considered in the article for processing steam fields in the summer and the studies carried out to determine their quality indicators will allow creating machine-technological units for promising mechanized technologies of tillage in arid agriculture.
On the role of wind direction in the thermal bar dynamics in autumn: A numerical study
Authors: Tsydenov B O 
Published: March 2023

Abstract
The effect of wind direction on the dynamics of the thermal bar in autumn was studied in Barguzin Bay of Lake Baikal by numerical modeling. An analysis of the temperature fields simulated showed that wind direction was essential to thermal bar development and temperature distribution. Easterly wind, in contrast to westerly wind, contributed to increased speed of the surface propagation of the thermal bar toward the open lake. The results presented here also demonstrate that autumnal cooling of Barguzin Bay was faster during easterly wind activity.
The influence of the level of Lake Tenis on the flooding and underflooding of agricultural land in the adjacent territory
Authors: Tusupbekov J A , Nadtochy V S 
Published: March 2023

Abstract
The processes of flooding and underflooding, observed during the overflow of closed reservoirs located in the conditions of a flat-depression flat terrain, may be the result of natural causes, when the incoming part of the water balance exceeds the outgoing part. In the case when the reservoir is flowing, the level rise is often associated with anthropogenic influence. In most cases, flooding processes are the result of a combination of causes, which in the general case can be natural and man-made. The correct choice of dewatering systems is possible only if the causes of waterlogging are precisely established. The article considers the consequences of flooding and underflooding of agricultural land (hayfields, pastures) of the “Tracts of Koshara” in the Tyukalinsky district, which is presumably associated with an increase in the level of Lake Saltaim - Tenis, regulated by a dam at the outlet of the Osha River (Ust-Logatka village) in Krutinsky area. In this regard, the purpose of the study is to determine the causes of flooding and the position of the boundaries of the zone of flooding of agricultural land in the Tyukalinsky district under conditions of an increase in the level of Lake Tenis.
Towards a Large-Scale “Green Energy”: Multifunctional Protective Coatings for Nuclear Engineering Structural Materials
Authors: Okunev V S 
Published: March 2023

Abstract
The main task of the research is to analyze the possibility of using tungsten protective coatings in fast nuclear power reactors cooled by a lead. The author uses computational and optimization research methods. A comprehensive analysis of the properties of tungsten, including the properties of thin tungsten coatings, has been carried out. The results obtained make it possible to consider tungsten coatings of structural materials as multifunctional protective coatings. They perform the functions of protecting against corrosion and erosion of structural materials in liquid lead. They increase the thermal conductivity of fuel claddings and contribute to a decrease in the maximum fuel temperature in the nominal and emergency operating modes of the reactor. The only disadvantage of tungsten when used in nuclear technology is associated with a high neutron absorption cross section. This disadvantage can be an advantage in minimizing the void reactivity effect. The necessary neutron balance is ensured by using a coolant based on lead thorium ores and innovative ceramic fuel with the addition of uranium metal nanopowder. The significance of research is determined by the possibility of the transition of nuclear energy to the status of “green” environmentally acceptable and safe energy in the near future.
Pleistocene gaps in the areas of birds of Eastern Siberia and their filling in the modern period of climate warming
Authors: Mel’nikov Yu I 
Published: March 2023

Abstract
Based on long-term studies (1968-2022), materials are presented on the change in the areas of birds in Eastern Siberia, caused by pronounced climate warming in the second half of the 20th - early 21st centuries. During the period of the last strong Pleistocene cooling, this territory was characterized by mountain-valley icing. As a result, the common areas of many bird species were torn apart. Subsequently, in isolated groups, evolution followed different paths, which led to the emergence of new closely related species. At present, due to the strong warming of the climate in Eastern Siberia (1.9°/100 years on average) and the change in the area boundaries of many bird species, the former gaps in their areas are being filled. For many bird species, secondary contact has been recorded with the formation of vast transitional zones in which their areas overlap to some extent. So far, there are relatively few of them, but the general trend towards overlapping areas of a number of bird species can be seen quite clearly. Among the species with area gaps without further speciation, shorebirds sharply predominate. However, among the species whose area gap ended in speciation, their number is significantly reduced. The current period of sharp climate warming and a significant change in the areas of birds in Eastern Siberia is characterized by a sharp increase in their biodiversity. However, it is combined with the low population density of many species, especially those new to the ecosystems of the region. Such a situation requires increased attention to the existing structure of the bird population and its dynamics, since it is observed extremely rarely - the shortest duration of the known centuries-old climate cycle is about 2000 years.

Published: March 2023

Abstract
The article presents the results of researching changes in the stream discharge in the forest-steppe zone in the XXI century in the conditions of the environmental regime. Due to the lack of data on the stream discharge within the researched area in previous years, the length of the channel network is considered as an indicator of water content – an indicator that generally correlates with the value of the length of the channel network. Elementary watercourses are taken as the object of research, since in short periods they are able to show high variability under the influence of external conditions, especially if it is necessary to establish the influence of specific local factors. The research was conducted on the territory of the “Sengileevskie Mountains” National Park, which lies within the Volga landscape region and the Low Volga region in the forest-steppe zone. This territory exists in the conditions of the nature protection regime and has a high forest cover. The research was based on the materials of the expedition work carried out in the summer of 2022. and the results of geoinformation analysis of topographic maps reflecting the position of the sources of elementary watercourses in 2001. As a result of the expedition work, the length of the channels of elementary watercourses as of 2022 has been established, the indicator of the change in the length of their channels in the XXI century – from 2001 to 2022 has been calculated. The fact of the multidirectional dynamics of the length of the channel network of elementary watercourses is established. In the conditions of the nature protection regime established at the beginning of the XXI century, against the background of the restoration of the landscapes of the researched territory, there is an increase in the length of the channel network of elementary watercourses, which has a correlation with the areal indicators of the restoration of natural plant communities – forests and meadows.

Authors: Kangash A I , Pankratov E V , Kosarev I A , Maryandyshev P A , Virk M S 
Published: March 2023

Abstract
The paper investigates the flow behavior near the NACA 64-618 airfoil profile of the blade tip section of a wind turbine for electric power production after a short icing event. The flow simulation considering the rotation speed of the wind turbine blade is performed to assess the effect of icing on the aerodynamic characteristics. Degradation of aerodynamic characteristics affects the electrical energy production of the wind turbine. The aerodynamic lift and drag coefficients are calculated for different angles of attack. The flow velocity fields near the airfoil are analyzed. The pressure coefficient distributions along the profile surface are obtained. The points of flow stall and changes of aerodynamic characteristics at different angles of attack are determined.

Exploring the Multidimensional Relationship Between Medication Beliefs and Adherence to Medications Among Older Adults Living With Multimorbidity Using Polynomial Regression: An Observational Cohort Study
Authors: Foley Louise , Doherty Ann S , Wallace Emma , Boland Fiona , Hynes Lisa , Murphy Andrew W , Molloy Gerard J 
Published: March 2023

Abstract

Background
People living with multimorbidity may hold complex beliefs about medicines, potentially influencing adherence. Polynomial regression offers a novel approach to examining the multidimensional relationship between medication beliefs and adherence, overcoming limitations associated with difference scores.

Purpose
To explore the multidimensional relationship between medication beliefs and adherence among people living with multimorbidity.

Methods
Secondary analysis was conducted using observational data from a cohort of older adults living with ≥2 chronic conditions, recruited from 15 family practices in Ireland in 2010 (n = 812) and followed up in 2012 (n = 515). Medication beliefs were measured with the Beliefs about Medicines Questionnaire-Specific. Adherence was assessed with the medication possession ratio using prescription data from the national primary care reimbursement service. Polynomial regression was used to explore the best-fitting multidimensional models for the relationship between (i) beliefs and adherence at baseline, and (ii) beliefs at baseline and adherence at follow-up.

Results
Confirmatory polynomial regression rejected the difference-score model, and exploratory polynomial regression indicated quadratic models for both analyses. Reciprocal effects were present in both analyses (slope [Analysis 1]: β = 0.08, p = .007; slope [Analysis 2]: β = 0.07, p = .044), indicating that adherence was higher when necessity beliefs were high and concern beliefs were low. Nonreciprocal effects were also present in both analyses (slope [Analysis 1]: β = 0.05, p = .006; slope [Analysis 2]: β = 0.04, p = .043), indicating that adherence was higher when both necessity and concern beliefs were high.

Conclusions
Among people living with multimorbidity, there is evidence that the relationship between medication beliefs and adherence is multidimensional. Attempts to support adherence should consider the combined role of necessity and concern beliefs.
Agnotology in Palestine/Israel
Authors: Fahoum Basma , Dubnov Arie M 
Published: March 2023

Abstract
This essay, a product of a reflection and dialogue between a Palestinian and a Jewish Israeli, revisits the so-called "Teddy Katz Affair," a heated debate that erupted first in 2000 but resurfaced recently due to a new documentary. The Affair was triggered by a newspaper article reporting about a master’s thesis, which relied heavily on oral testimonies, that concluded that war crimes against Palestinians were committed during the 1948 War in the village of Tantura. After chronicling briefly the sequence of events — which included a libel suit, a public debate, and retraction of the thesis by the university — this article assesses its broader impact on the historiography of Palestine/Israel. Finally, it proposes to employ the term “agnotology” to describe the mechanisms that were developed to distort and silence Palestinian narratives in Israel. Agnotology, it is suggested, is a concept that better captures the hierarchies of knowledge that were used to distinguish Jewish testimonials from Palestinian memories and the process by which they were absorbed and codified by academic historians following the Affair.
III—Sympathy, Empathy, and Twitter: Reflections on Social Media Inspired by an Eighteenth-Century Debate
Authors: Herzog Lisa 
Published: March 2023

Abstract
How can the harm caused by waves of fake news or derogatory speech on social media be minimized without unduly limiting freedom of expression? I draw on an eighteenth-century debate for thinking about this problem: Hume and Smith present two different models of the transmission of emotions and ideas. Empathetic processes are causal, almost automatic processes; sympathy, in contrast, means putting oneself into the other person’s position and critically evaluating how one should react. I use this distinction to argue that the architectural logic of social media should be improved to prevent cumulative harms and to facilitate sympathetic processes.
