Degeneration Theory and Dostoevsky’s The Brothers Karamazov
Authors: Sciarrini Marco
Published: March 2024

I am here interested in presenting a comparative analysis between the strand of thought known as ‘Degeneration Theory’ and Dostoevsky’s last major novel, The Brothers Karamazov. I will provide a brief contextualization about the influence of Degeneration Theory on Russian thought, postulating that the principal Russian preoccupation concerning degenerate attitudes – above all in Dostoevsky -  consists in the disease of moral nihilism. I proceed by outlining the criminal type in The Brothers Karamazov by focalizing my inquiry around the figure of the illegitimate epileptic brother Smerdjakov. My main arguments around the question of social and physiological degeneration will be developed in the subsection devoted to the relationship between poverty and children, whose humility, it is argued, represents Dostoevsky’s answer to the death of God and the moral bankruptcy enacted by nihilistic tendencies. In the third segment I will analyse the maddening outcomes of this disease in my discussion of Ivan Karamazov. Lastly, I will venture into a more unreserved discussion about the purported sequel to The Brothers Karamazov. This study seeks to emphasize the importance in the relationship between characters and the God question, ultimately claiming that for Dostoevsky physical degeneration is deployed as a physiological counterpart for the chief concern of many degenerationist narratives: the spiritual degradation of the individual soul and of the integrity of civilization.

ENERGY POTENTIAL OF DISTRIBUTED GENERATION AT POWERFUL BOILER HOUSES OF UKRAINE IN CONDITIONS OF MILITARY AGGRESSION
Authors: Teslenko O.I.
Published: March 2024

The Integrated Power System of Ukraine (IPS) is purposefully destroyed by the russian aggressor and suffers significant damage, which has caused long-term emergency interruptions in the power supply of critical infrastructure facilities, enterprises and the population. One of the ways to increase the stability of the IPS of Ukraine is to increase the share of distributed generation in its composition. The conceptual idea of solving this problem is the transformation of existing critical infrastructure objects from electricity consumers into electricity producers/suppliers who will provide their own electricity needs and the needs of other electricity consumers. Boiler houses of centralized heat supply systems (DHS) of Ukrainian cities with their existing electric power and fuel infrastructure can become such objects in wartime conditions. The author proposes the widespread introduction of energy-efficient cogeneration gas-piston units (CGPUs) at boiler houses of the DHS. The container-type CGPU is a typical mass-produced equipment that is manufactured in Ukraine and abroad and has a short implementation period (up to 5 days from the date of delivery to the industrial site of the boiler house). The high maneuverability of the CGPUs allows for an increase the flexibility of the IPS of Ukraine. The article presents the main technical and economic indicators of distributed generation with the use of CGPU at existing boiler houses for further national planning of the development of distributed generation during the martial law and post-war reconstruction of Ukraine. The application of CGPU at boiler houses of the DHS of Ukrainian cities has the potential to provide additional distributed generation with a total capacity of up to 2365.7 MW, in particular, 1224.8 MW at 158 boiler houses with a thermal capacity of 100 Gcal/h and more (612 CGPUs with an average unit electric power of 2.0 MW each); 561.9 MW at 409 boiler houses from 20 to 100 Gcal/h (803 CGPUs of 0.7 MW each); 561.9 MW in 2101 boiler houses from 3 to 20 Gcal/h (4136 CGPUs of 0.14 MW each). Under the conditions of 8 hours a day of use of the installed capacity of CGPUs, 567.8 thousand MWh of electricity will be produced every month at the boiler houses of the DHS (taking into account the consumption of the boiler houses for their own needs and release to the network to other consumers) and 136–142 million cubic meters of natural gas will be consumed. According to the average specific cost of modular CGPU (turnkey supply) from 800 to 950 USD/kW of installed electric capacity, capital costs for implementing the CGPUs with a total capacity of 2,365.7 MW will amount to USD 1.89–2.25 billion.

The task of obtaining of iron-containing secondary raw materials from finely dispersed oily slag accumulated in the dumps of metallurgical plants of Ukraine is important and urgent. This slag contains from 60 % to 75 % of iron oxides. Every year, up to 2.5 million tons of it is dumped into the dumps of PJSC “Kryvorizhstal” alone. To determine the favorable conditions for degreasing and cleaning of dump slag, studies of its structure, composition, physicochemical and technological properties were conducted. It is shown that, in addition to iron oxides, oil and water, there is a significant amount of more than 30 % of the amount of organic matter. The relative amount of components is different. A liquid reagent for the separation of organics from the starting material is defined. When the slag cleaned of organic matter is heated to 500 °C, a gradual decrease in the mass of the sample occurs, until it stops with exposure, with the preservation of all original iron oxides, FeO, Fe3O4 and Fe2O3, in the final product, in the absence of oil. When the slag is further heated to 950 °C, up to 97.5 % of hematite, Fe2O3, was obtained as the final product. In addition to hematite, oxides of other metals and more than 1.3 % of quartz are present in the final product in small quantities, up to 1.2 %. Bibl. 12, Fig. 8, Tab. 1.

Published: March 2024

Purpose. This paper focuses on the case of a rock slope in the Ouarzazate region in order to conduct a sensitive analysis to study the influence of seismic action orientations on wedge stability. Methods. To examine the wedge stability, a probabilistic approach related to the Monte Carlo method has been used. Firstly, the characteristics of joint families: orientations and fillings are analysed. Then, the influence of the seismic action on the rock slope stability for the most sensitive plunges is studied using the equations developed by J. Bray (1981). These equations make it possible to ultimately determine the safety factor for predicting the stability of the wedge. Findings. In this study, the ranges of values of the seismic action orientations leading to the rock wedge failure have been identified. Especially around the 284° trend, the minimum of the safety factor values have been obtain for different analyzed plunges. This means that the occurrence of an earthquake oriented at 284° and lateral to the slope disposition, oriented at 260°, gives rise to a risk of a slope failure. Originality. This study of rock slope stability made it possible to find the minimum safety factor values depending on the orientation of the seismic action by examining its sensitivity to all possible orientations: combinations of plunges and trends. Practical implications. This analysis makes it possible to find, whatever the orientation of the seismic action, the safety factor corresponding to the stability of the rock slope. Thus, a decision can be made on the appropriate reinforcement to ensure the rock slope stability, taking into account the case of the most unfavourable seismic action orientation found in this analysis.

Published: March 2024

Purpose. Surface water from mining activities may undergo various physico-chemical changes that can impact its quality and ecological health. This study conducted a comprehensive physico-chemical assessment of surface water affected by mining operations, with a particular emphasis on heavy metal content. Methods. These parameters were chosen due to their importance as indicators of water quality and potential contamination. Water samples were collected from different locations within and around Maiganga Coal mine area and analyzed using standard laboratory techniques. The assessment included the measurement of physico-chemical parameters such as temperature, total dissolved solids and concentrations of heavy metals such as chromium, lead, manganese, cadmium and copper. Also, cations and anions such as calcium, magnesium, sodium, potassium, nitrate, chloride sulfate and fluoride that can impact water quality were considered. Findings. The results of the physico-chemical assessment revealed substantial variations of chromium (0.00-0.03 mg/l), lead (0.00-0.05 mg/l), manganese (0.00-12.11 mg/l), cadmium (0.10-0.14 mg/l) and copper (0.00-1.02 mg/l) concentrations. Also, cations and anions such as calcium (0.00-1.13 mg/l), magnesium (11.90-30.07 mg/l), sodium (0.20-1.11 mg/l), potassium (0.10-0.66 mg/l), nitrate (3.90-4.78 mg/l), chloride (84.0-319.0 mg/l), sulphate (8.0-240.0 mg/l) and fluoride (0.00-0.89 mg/l) can impact water quality levels across the sampled surface water bodies. Originality. Evidence of acid mine drainage, caused by mine effluents that are limited to surface water and do not reach groundwater, has been found through analysis of data from wells, ponds, and streams. Practical implications. These variations obtained could be attributed to the discharge of acidic or alkaline substances associated with coal mining activities.

Purpose. The research aims to substantiate the technological solutions to ensure the rock mass stability through a rational approach to strengthening the zones of increased rock pressure behind the longwall face. Methods. To achieve the purpose set, a complex research method is used, which includes an analysis of practical experience in mining medium-thickness flat-lying coal seams, a study of the stress-strain state of rocks above the coal mass marginal area, and mine research into the influence of mining-technical factors on the state of zonal preparatory workings. Findings. The patterns of stress influence on the mine working stability have been determined depending on the mining-technological parameters of mining operations. Empirical dependences of the stress influence on the mine working stability have been revealed. The parameters of stress influence on the mine working stability have been found depending on the mining-technological parameters of mining operations. Originality. The conducted research made it possible to determine the degree of influence of mining-technical conditions of mining operations on deformations in border rocks with various types of support in extraction workings, which helps to understand the dynamics of deformation processes occurring in the coal-rock mass surrounding mine workings maintained behind the longwall face. Practical implications. The revealed deformation patterns can be used in calculating the rock pressure manifestations when conducting mine workings on deep levels under various mining-technical conditions of mining operations, which has practical significance for ensuring the stability and safety of maintaining mine workings at the stage of mining operations. The use of roof-bolt support is proposed as an effective means not only to ensure stability, but also to maintain safe operating conditions in mine workings.

Published: March 2024

Purpose is to study safe life of industrial (metal) structures under long-time operation in the corrosive-active media of oil and gas wells with the help of neural network analysis. Methods. The MATLAB system (MATrix LABoratory) was selected as the tool environment for interface modelling; the system is developed by Math Works Inc. and is a high-level programming language for technical computations. Of the three existing learning paradigms, we used the “with teacher” learning process, as we believed that a neural network had correct answers (network outputs) for each input example. The coefficients were adjusted so that the network gave answers being as close as possible to the known correct answers. Findings. An artificial neural network has helped obtain a generalized diagram of the expected areas of high viscoplastic characteristics of carbon steels used to manufacture metal structures in the oil and gas industry. While applying the trained neural networks, generalized dependences of the corrosion rates of structural steels on the parameters of media with different concentrations of chlorine ions, sulphate ions, hydrogen sulphide, carbon dioxide, carbon dioxide, and oxygen ions were obtained; they were the basis to predict corrosion behaviour of steels. Originality. For the first time, the possibility of applying neural network modelling to predict local corrosion damage of structural pipe steels has been shown in terms of the “steel 20 – oxygen and chloride-containing medium” system. For the first time, the technological possibility has been demonstrated to use neural network analysis for engineering predictive assessment of corrosion activity of binary systems of simulated solutions, which are most often found under industrial conditions of the oil and gas sector of the economy. Practical implications. The proposed technology of using the neural network analysis will make it possible to expand a range of predicted values beyond experimental data, i.e. to predict the value of Vcor in very dilute or concentrated salt solutions within the acidified and neutral pH ranges. It should be noted that the error of the prediction results shown by the neural network will increase along with distancing from the scope of experimental data.

Purpose. Determining a relationship between the shear/failure of the rock mass and the technogenic earthquakes caused by them during underground mining of ore deposits with the derivation of an equation for the dependence of the technogenic earthquake indicators for the conditions of the Zhezkazgan copper-ore field. Methods. The research methodology consists of studying and analyzing early research on technogenic earthquakes by the method of statistical data processing. Calculation of rock mass deformation distribution in the study area is based on numerical modeling in the Comsol Multiphysics 5.6 and MATLAB 2020 software package environment. Calculations are performed based on solving a plane problem using the Finite Element Method (FEM). Findings. Based on the transition from the failure area to subsidence and shear values of the overlying rock mass stratum, an equation for the dependence of the earthquake magnitude on the numerical values of the mass subsidence or shear has been obtained. Originality. For the first time, based on the physics and geomechanics of rock mass shear processes, empirical-analytical formulas have been obtained that make it possible to predict the technogenic earthquake magnitude during underground mining of ore deposits in the conditions of the Zhezkazgan copper-ore field. Practical implications. Preliminary predictive calculations made by the obtained formulas for the conditions of the active mine No. 31 of the East-Zhezkazgan mine, ТОО Kazakhmys Smelting, show acceptable results of magnitude value, comparable to in-situ measurements during field mining. This prediction makes it possible to pre-calculate the technogenic earthquake magnitude at the stage of designing mining operations and make appropriate scientifically sound decisions during further mining of the field.

Published: March 2024

Purpose.The research aims to substantiate the general provisions on coordination of the experimental-analytical research results of the influence of pre-drilled wells on the intensity of gas-dynamic phenomena manifestations (using the example of the mining-geological conditions of the phenomena at the PJSC Mine Administration Pokrovske, Ukraine). Methods. The research uses an integrated methodology consisting of indirect experimental methods for studying the adjacent rock mass state and tendencies. Findings. It has been proven that indirect experimental indicators of the rock mass state around the tunneling face are related to the peculiarities of the distribution of its stress-strain state components. Based on this research, the well lengths of up to 10-15 m has been determined to effectively and safely de-stress the rock mass. The experimental research validity is confirmed by conducted computational experiments, in the course of which the dependence of the propagation parameters of the stress-strain state component concentrations on the degree of hardness of the lithotypes is revealed, and a geomechanical substantiation to the tendencies of propagation of rock pressure anomalies near stoping and tunneling faces is given. The new knowledge obtained is the basis for creating a method for calculating rational parameters for the location of de-stressing pre-drilled wells. Originality. An objective assessment of the degree of adequacy and reliability of the computational experiment results has been made under the condition of using a new geomechanical model with mine studies of seismic-acoustic signal parameters and the initial gas release velocity. The main tendencies of vertical σу, horizontal σх and σz, as well as stress intensity propagation have been identified. The obtained results of exploring the bottom-hole mass are aimed at substantiating the parameters of anti-outburst measures for all preparatory mine workings. Practical implications. The conducted research is implemented in creation of a calculation method and recommendations for the selection of rational parameters for the location of de-stressing pre-drilled wells for the purpose of weakening the rock mass, surrounding the tunneling face, and reducing the probability of gas-dynamic phenomena occurrence due to the controlled weakening of adjacent rocks.

Published: March 2024

Purpose.The research purpose is to assess the stability of mine workings driven in a stratified rock mass by studying the influence of the stratified rock bedding angle on the rock mass stress-strain state (SSS). Methods. The research uses both experimental and numerical methods. Experimental studies are carried out using rock samples with different angles of rock layer occurrence, while numerical modeling is performed using the RS2 (Geotechnical Finite Element Analysis) software based on the generalized Hoek-Brown failure criterion. The studies are carried out on models covering the border area of the mine workings driven in the mass with the angles of rock occurrence from 0 to 75°. Findings. Experimental and numerical studies have shown that when the rock layer inclination angle changes, significant changes occur in the stress concentration zones around the mine workings. An increased rock layer inclination angle is accompanied by a change in stress distribution, which is important for assessing the stability of mine workings. A particularly strong influence is observed at the angles of rock occurrence 30° and above. Originality. The research novelty is in revealing the patterns in the stress distribution in the stratified rock masses depen-ding on the rock layer inclination angle. Research results provide new data on the rock interaction mechanisms in difficult geological conditions. Practical implications. The results obtained can be used in the planning and operation of mine workings in difficult geological conditions. By taking into account the changes in stress zones caused by the rock layer inclination angle, it is possible to improve the safety and efficiency of mining operations.

Methods. This study is based on geological mapping, drill core and petrography analysis in combination with ICP-AES, XRD, and SEM data. Findings. The detailed mineralogy consists mainly of sulfides and sulfosalts. The main ore minerals include arsenopyrite, pyrite, sphalerite, chalcopyrite, galena and bismuthinite. Mineral inclusions related to isomorphic sulfosalts are found in galena and/or chalcopyrite. They include matildite, galenobismutite, pavonite, cosalite, schirmerite, krupkaite, ramdohrite, wittichenite, emplectite, luzonite, gustavite, hedleyite, krennerite, wittite, freibergite, tetrahedrite, tennantite and native bismuth. The supergene minerals are anglesite, covellite, malachite, azurite and goethite. In addition, specific replacements are observed between dolomites and sulfides, indicating an interaction between hydrothermal fluid and host rocks. Four ore stages have been identified based on the relationship between mineral phases and ore-forming conditions. The results of this study indicate that Ag and Au precipitation is controlled by the Bi-Te-Pb-S system, while enrichment in Bi, Te and Se sulfosalts and Bi-telluride indicates a magmatic source of the ore-forming fluid. Originality. The study delves into the genetic model of the Amensif Zn-Pb-Cu-Ag±Au-Bi deposit in the Western High Atlas, Moroc-co, with a focus on carbonate replacement textures, while also exploring its classification as either a carbonate replacement deposit or a skarn deposit. Practical implications.Mineral textures are indicators of the replacement process in the Amensif Zn-Pb-Cu-Bi-Ag±Au carbonate replacement deposit (the Western High Atlas, Morocco). The results obtained from this research paper can be used as a powerful tool in mineral exploration of the Western High Atlas.

Purpose. The primary objective of this research is to develop a technology for achieving water quality at the level of Maximum Permissible Concentrations (MPC) required by sanitary regulations and norms. Methods. To meet these regulatory requirements, experimental studies were conducted to analyze the chemical and microbiological composition of water, focusing on parameters such as the total microbial count (quantity/ml), coliform bacteria (quantity/ml), coliphages (quantity/100 ml), clostridia (cl/20 ml), and other harmful substances. The research also examined water disinfection processes depending on the autumn and winter seasons of the year. Findings. To assess the device’s effectiveness, the research determined the optimal ozone concentration and contact time in the disinfection chamber. The findings indicate that 0.6 grams per hour (G = 0.6 g/hour) of ozone (O3) per cubic meter of surface water is sufficient for the removal of harmful microbiological substances. Originality. The primary innovation in this research lies in the establishment of parameters for an ozone generator utilizing a novel corona discharge method. The study introduces both theoretical frameworks and practical methodologies for effectively disinfecting surface waters using this innovative technique. Practical implications. This case study offers insights that can be applied and replicated in regions facing similar water quality challenges.

Published: March 2024

The column chromatography method was used with brick sand particles as an adsorbent for the removal of heavy metals (Cr, Fe, and Pb) from the aqueous solution. These metals can pollute water, and soil and also come in contact with the food chain, causing life-threatening health issues in the human body. The pore volume and the specific surface area of the brick sand particles were determined using the standard method which was 44.41% and 29.4 m2/g respectively. The different concentrations of toxic metals in the water solution were considered to determine the adsorption capacity of the adsorbent. The adsorption methods were able to remove about 94% of Cr, 24% Pb, and 69% Fe from the aqueous solution. From the investigation results, we may conclude that raw brick sand particles can play a vital role as an adsorbent in the treatment of heavy metal-contaminated wastewater. Moreover, the saturated adsorbent can be used as an element of construction materials to prevent further pollution.

DNA barcoding and morphological characters together with thorough bioecological investigations to diagnose field bean pod borer, Adisura atkinsoni Moore, 1881 an important pest was carried out. A. atkinsoni has a limited host range. The incidence of Adisura was higher on local varieties (photo sensitive) compared to HA4 hybrid (photo-insensitive). The field bean pod borer appeared during middle of October and continue to March. The undefined taxa were identified using both female and male genitalia. But since they could be differentiated from their morphologically closest relative, they were marked as sensu lato. While doing BLAST analysis, the mitochondrial COI Sequence of Adisura specimens collected from Bengaluru showed similarity to A. bella. In the phylogenetic tree, these two samples Sp1 and Sp2 separate new sub-clade which stands separately from the rest of the Adisura species. It was identified that the lepidopteran samples collected from Bengaluru are Adisura and the DNA sequences did not match with any of the existing species of Adisura. The shift in this pest’s prevalence has been discussed.

Odonata diversity study was carried out from September 2020 to October 2022 in the Mettur Dam, Salem District. Among the total 40 different species, 27 species were in Anisoptera (dragonflies) and 13 species in Zygoptera (damselflies) under five families. Libellulidae was the largest family recorded (16 species), followed by Coenagrionidae (11), Aeshnidae (2), Lestidae (2) and Gomphidae (1). A migratory species, Pantala flavescens, was the most dominant in numbers throughout the year. Maximum number of individuals was found during September 2020 to September 2021. Odonata diversity was higher in the first season of 2021 than in next second season. Both dragonflies and damselflies mainly used wetlands of the dam ecosystem and agricultural fields rather than shrubland.

In the study on the diversity of pollinators and their pollination efficiency in sunflower (Helianthus annuus L.) under field condition of Odisha during 2021-22, recorded 18 species of pollinators. Indian honeybee, Apis cerana indica F. (Hymenoptera, Apidae) was found to be the major one among the insect pollinators. The experiment conducted for two years with three different treatments viz., open pollination (OP), managed A. cerana indica pollination (HB) and pollinator exclusion (PE) for better yield and quality revealed that both quantitative and qualitative parameters were significantly higher in OP sunflower crops followed by crops pollinated by A. cerana indica. Significantly higher seed yield, 1000 seed weight, percentage of seed filling and number of seed per capitulum were recorded in these treatments. These findings indicate OP and HB increase 33 per cent more yield in sunflower.
Effects of sublethal concentration of Imidacloprid on the enzyme activity of sweet potato weevil, Cylas formicarius (Fabricius) (Coleoptera, Brentidae)
Authors: Vinod Anjali , Jayaprakas C.A.
Published: March 2024

Application of sublethal (LC10 and LC30) dose of Imidacloprid on sweet potato weevil (SPW) was found to have inhibitory effect on its enzymes viz., glutathione reductase (GR), glutathione peroxidase (GPx), reduced glutathione (GSH) and glutathione S-transferase (GST), while activity of superoxide dismutase (SOD) and lipid peroxidase (LPx) was up regulated when compared to control. The weevil’s expression of SOD increased by 13.53 and 69.44 and LPx by 67.38 and 73.04 per cent respectively, when the sublethal dose was raised from LC10 to LC30. Although GST and GPX did not alter considerably after exposure to the sublethal doses of imidacloprid, weevil activity of GR (65.5-78.1%) and GSH (42.2 and 61.6%) decreased significantly.
