Authors: Sedyaaw Panchakarla , Kawade S.S , Bhaladhare Darwin Ratnaghosh , Pranali Kamble , Pandey Ayushi
Published: December 2024

A common environmental problem brought on by the atmospheric deposit of acidic accoutrements is acid rain. This abstract looks into the colourful aspects of acid rain, emphasizing its sources, consequences and strategies used to lessen its dangerous impacts. Anthropogenic emigrations of sulphur dioxide and nitrogen oxides, primarily from the burning of fossil energies and artificial processes, are the main causes of acid rain. Another factor contributing to this complex miracle is natural sources like stormy eruptions. The goods of acid rain span colourful ecosystems, impacting submarine life, soil quality, foliage and mortal health. Acidification of water bodies disrupts ecological balance, causing detriment to submarine organisms and posing a trouble to biodiversity. Also, acid rain’s ecological goods are made worse by the release of poisonous essence into the terrain. Enhancing energy effectiveness and promoting indispensable energy sources are two sustainable practices that support a holistic strategy to reduce precursors of acid rain. One naturally being remedy that helps restore acid rain- affected ecosystems is reforestation. Understanding the sources, impacts and measures of acid rain is essential for developing effective programs and practices that promote sustainable cohabitation with our earth as humanity tries to strike a balance between development and environmental preservation.

Published: December 2024

Background: The impact of global warming on the environment is affecting soil quality and water supplies, which in turn is impacting agricultural production. The rise in salt concentrations in soil and water systems due to increased evaporation rates from warming temperatures and changing precipitation patterns is a major concern. This salinity poses a threat to crop development, especially for sensitive species like the green gram (Vigna radiata L.), a protein-rich legume consumed globally. Understanding the effects of salinity on green gram growth and physiological responses is essential due to its importance as a significant food source. Methods: A pot experiment was conducted at ADACandRI, Trichy, with varying EC values (less than 1, 2, 4, 6, 8, 10 and 12 dS/m) to study the effects of different saline irrigation levels. The experiment utilized the green gram variety VBN 2 in a randomized design with three replications. Growth parameters including plant height, number of leaves and branches, blooming period, root, shoot and leaf lengths were measured. Biochemical characteristics such as protein concentration, reducing sugars, proline and chlorophyll levels were also analyzed. The study evaluated the impact of these characteristics on salinity tolerance using Principal Component Analysis (PCA). Result: Salinity stress negatively affected growth and metabolic reactions in greengram. The VBN 2 variety exhibited better growth and biochemical reactions at a moderate salinity level of 2 dS/m compared to higher salinity levels, indicating moderate salt tolerance. Plant height, leaf growth and flowering time improved with lower salinity levels but decreased significantly at higher salt levels. Important characteristics such as plant height, chlorophyll content and proline accumulation were key factors in determining the plant’s ability to tolerate salt stress, as indicated by PCA analysis.

How can sociology of morality exist? Mental dialogue with G.S. Batygin
Authors: Malinkin Alexander
Published: December 2024

This historical study examines an article by G.S. Batygin about sociology of morality, in which he proves its impossibility. The author sees the relevance and significance of the article in the fact that it has become a dividing milestone on the path from the “old” to the so-called “new sociology of morality”. The argumentation of G.S. Batygin is reconstructed, the main provisions and concepts of the article are critically analyzed. For comparison, the points of view on sociology of morality of other Russian authors are provided, who believe that this sociological discipline is not only possible, but actually exists. According to the author, the moral phenomena themselves are interpreted by G.S. Batygin not entirely correctly — only as reflected phenomena of consciousness — obviously because this corresponded to the requirements of the scientistic paradigm which he decided to adhere to in his article. Nevertheless, the author believes that within the framework of this paradigm, G.S. Batygin’s argumentation aimed at proving the impossibility of morality is irrefutable in notional and logical respects. But if it is proven that scientific sociology of morality is impossible, then the question arises whether it is possible in another paradigm and based on another way of cognition, namely philosophical? The path towards it was outlined by the pioneer of the sociology of morality, E. Durkheim, as noted by G.S. Batygin. The author considers M. Scheler’s “material ethics of values” and “sociology of knowledge” as examples of philosophical sociology of morality. In conclusion, he characterizes his own theoretical and methodological position, in light of which Batygin’s article is regarded as a morally significant act.
On the Relationship Between Emotional Intelligence and Personality Traits with Attitudes Toward a Sensitive Topic (Using the Problem of Domestic Violence as an Example)
Authors: Larina Tatiana
Published: December 2024

The article presents an overview of the results of an exploratory empirical study conducted by the author with the purpose of testing the relationship between subjective factors such as emotional intelligence and the Big Five traits with attitudes toward sensitive topics in sociological surveys (using the problem of domestic violence as an example). The topic of domestic violence was chosen because it is actively discussed in the media discourse, but at the same time, it still remains rather a taboo for Russian society. The sensitivity of the questions is determined not only by the topic, but also by the personal context, so emotional intelligence and personality traits were chosen as subjective factors for the study. To measure emotional intelligence, we used the N. Schutte test as a reliable, valid and at the same time not too voluminous tool for a psychological technique, and to identify the traits of the Big Five, we used the technique of M.S.Egorova and O.V.Parshchikova. Some of the questions on domestic violence were taken from surveys by VCIOM (2011, 2019) and FOM (2019), and the author's questions were also added, including a "sincerity scale", according to which the respondent could assess at the end of the questionnaire the degree of his sincerity in answering the questions asked. The subjects were students aged 18-24 (n= 125). There was carried out a comparison of the obtained results with the results of surveys on the topic of domestic violence by VCIOM and FOM for the age group of 18-24 years, as well as a correlation analysis, which revealed the presence of a weak relationship between the indicators of emotional intelligence, extroversion and attitude towards the topic of domestic violence. As a result, a very significant conclusion was obtained that a high level of emotional intelligence is associated with the sincerity of respondents when answering sensitive topics. The article will be of interest primarily to specialists interested in the methodology of sociological research and interdisciplinary research.
Scientific Supervisor and Scientific Mentor: Updating Old Roles and Meanings
Authors: Ambarova Polina , Shabrova Nina , Kemmet Elena
Published: December 2024

This article examines the development of the scientific mentoring institute in Russian universities. The authors assume that it should be based on scientific ideas about the content and features of the professional roles of a scientific supervisor and a scientific mentor. Despite all the similarities, these roles of research and teaching staff correspond to different functional areas of their activities with their own set of tasks, results, and features of interaction with students. The purpose of this article is to compare the professional roles of a scientific mentor and a scientific supervisor of undergraduate and graduate students for the purpose of updating the meaning of mentoring activities in the field of university research work. The subject of the analysis is the features of the professional role of a student's scientific mentor. Their presence substantiates the independent nature of mentoring activities and "legitimises" it in the role repertoire of research and teaching staff of universities. The empirical basis of the article is the materials of semi-structured interviews with research and teaching staff of Russian universities, conducted within the framework of an all-Russian study (n = 30, 2024). The interpretation of the empirical data is based on the theoretical provisions of the sociological theory of roles, the theory of social identity, the concept of professional morality and ethics. The study not only substantiates the differences in the functional content of professional roles and everyday practices of a supervisor and a mentor, but also reveals the paradoxes of the professional identification of supervisors and mentors, the moral and ethical dimension of their activities. It is shown that the features of the prescriptions, expectations and performance of their roles by supervisors and mentors are manifested in the degree of formality of their rights, duties and responsibilities, the level of individualisation and the nature of the temporal organisation of interactions with students. The practical significance of the results obtained is associated with the possibility of developing university programs to support mentors as key actors in involving students in the academic profession and university science. The role differences between a scientific mentor and a scientific supervisor allow us to further specify the management requirements for different types of professional activity of scientific and pedagogical workers, as well as optimize their resource support. The practical significance of the study for academic workers is to obtain grounds for self-assessment of their readiness for the professional role of a scientific mentor and to determine the areas of professional responsibility associated with this role.
Peculiarities of Public Spaces Perception by Muscovites with Limited Mobility (Based on Two Urban Locations)
Authors: Naberushkina Elmira , Sudorgin Oleg , Sidorenko Sergey , Radchenko Elizaveta
Published: December 2024

This article analyses the accessibility of the urban environment for various groups of people with limited mobility. Moscow is considered a complex space that includes “old”, historically developed and “new”, modern territories, which, however, do not have clear zoning and, within the Moscow Ring Road, are located nearby, and often inside the “old”. Many groups of Muscovites with limited mobility are narrowed to people with disabilities with musculoskeletal problems, elderly citizens, and mothers with children. The basis for such abstraction was the institutional definitions of people with limited mobility contained in the laws of the Russian Federation. The empirical study consists of three complementary parts. Stress tests were conducted for elderly citizens, which made it possible to identify the main difficulties with the accessibility of the urban environment and attitudes towards them. The article also analyses the accessibility of the "old" Moscow space using the example of the Aeroport metro station for elderly people and mothers with children over five years old. Problems in the planned and declared inclusiveness of the new space are identified using the example of Zaryadye Park. It is shown that the urban environment of Moscow can be considered as possessing subjectivity (in accordance with the definition of B. Latour), since it determines the life of people with limited mobility. Different priorities of the inclusiveness of the environment for temporarily and permanently disabled people, as well as for different age groups, are revealed.
The analysis of new spaces showed that modern design, taking into account the requirements of inclusiveness, did not manage to avoid obstacles for people with limited mobility. The authors conclude that there is a need for a broad study of various groups of permanently and temporarily mobile citizens, of their interests, priorities, value systems and prospects for coordinating these interests in the design of a modern urban environment, especially in such a complex space as Moscow. The authors believe that the results obtained can be applied both in the development of Moscow urban planning and in the development of general urban planning principles.
Russians' perceptions of key components of the quality of life and social justice: a cross-section of public opinion in 2024.
Authors: Barash Raisa
Published: December 2024

This article, based on the latest sociological research data, examines how the current crisis conditions affect Russians' perception of their well-being, their satisfaction with various aspects of everyday life and their ideas about a just state. The author notes that, despite the difficult socio-economic conditions, many Russians have emotionally adapted to the crisis situation, which was greatly facilitated by the growing importance of intangible factors of well-being, primarily harmonious family relations and friendship ties. Based on the studied data, the author notes that many Russians perceive interpersonal relations with their closest circle as a key element of their well-being, which indicates not only the importance of intangible values of communication and emotional comfort, but also the mass demand for stable social ties.
Despite the growing influence of non-material factors on citizens' self-assessment of their quality of life, their subjective well-being is largely influenced by the structural social inequalities historically established in society: age, property and geographical inequalities. Young people and residents of large cities more often assess their lives positively, while representatives of older generations and residents of rural areas tend to express a more negative view of their well-being. This difference in perception is also observed in assessments of the availability of quality medical services, where residents of cities, especially megacities, have clear advantages.
In the perception of modern Russians, an important component of personal well-being is also life in a justly organized society, and the idea of social justice remains relevant for the majority of citizens. Russians understand social justice primarily as equal opportunities for self-realization and success for all citizens. But, although during the post-Soviet period the idea of income equality lost to the demand for the creation of favorable preconditions for self-realization, today more than a third of Russians prefer equal access to life benefits to equality of “starting conditions”.
The author concludes that today public opinion has formed a demand for the active participation of the state in ensuring social justice, which is strengthened under the influence of crisis trends.
Migration Policy in the Nizhny Novgorod Region: Subjects and Management Practices
Authors: Danilova Natalia
Published: December 2024

The article examines a regional model of migration policy based on the example of the Nizhny Novgorod Region. A distinctive feature of the author's approach is the understanding of regional migration policy as a set of management practices that include both government bodies and public organisations. This approach allows us to consider migration policy as a multifaceted and complex sphere of interactions between various subjects, as well as to increase the effectiveness of the programs implemented within its framework. The main tasks in the sphere of migration policy in the region are the adaptation and integration of migrants, but there is no clear definition of these concepts and actions for their implementation. The main organisational and management structures in the region are the Migration Department of the Ministry of Internal Affairs of the Nizhny Novgorod Region, interethnic councils operating under the governor of the region and the administration of Nizhny Novgorod. Activities to include foreign citizens in regional society are not directly included in the functionality of specialised government bodies, but can be compensated by the activities of public associations. Therefore, civil society institutions, both registered associations and informal diaspora communities, should be included in management practices. In addition, unlike government bodies, they have the ability to promptly respond to requests from foreign citizens. It is noted that the identified groups of institutions participating in the implementation of migration policy have specific resources, which predetermines their functionality and the nature of their activities in management practices. Organisational and managerial institutions rely on administrative and legal resources. As the resources of civil society institutions serve communication channels among foreign citizens, high immersion and involvement in the problems of labour migrants living in the region. These circumstances require their inclusion in the development and implementation of target programs and activities of adaptation and integration orientation. The author concludes that it is advisable to create a specialised agency in the region responsible for the development and implementation of activities within the framework of regional migration policy.

The use of the object geopositioning for the increase of the accuracy of the protection operation of the supply lines of the traction power supply system
Authors: Sulimin Artem , Kucenko Sergey , Ivanov Mihail
Published: December 2024

Purpose: false tripping on the supply lines of the contact network when passing an insulating interface leads to dangerous situations on the railroad, e.g. annealing and burning of contact wires, arcing. Also false disconnections can lead to stoppage of rolling stock on the guiding gradient and, thus, reduce throughput and transportation capacity. To solve the problem, namely to exclude false tripping of fast-acting switches, the paper proposes a method of using GPS/GLONASS transmitters to improve protection devices on supply lines. Methods: the research is carried out on the basis of theoretical knowledge of new developments related to geopositioning of rolling stock, theory of electric and magnetic circuits and theory of traction power supply. Results: this paper formulates and studies the concept of loading the set point of feeder line protection devices based on the data of current collector location on the electric rolling stock relative to the isolating coupling. Also each block of the complex of devices and principles of their operation are described in detail. The graphs of change of current setting of fast-acting switches are constructed and the variant of modernization of their design for operative change of current setting is offered. Practical significance: the result of the work is of importance, first of all, for ensuring reliability, uninterrupted operation of the traction power supply system and increasing the throughput and carrying capacity. The presented work sets a new direction for the development of protection devices in the DC traction power supply system using a new type of transmitted data – the geographical position of the rolling stock. Thus, the work demonstrates the possibility of introducing new technologies for determining the position of the object in the relay protection system of the contact network.

Authors: Suhardi Dayang Nur Syahidah Abang , Razali Asbah , Razali Nur Azah , Hashim Nurhamizah , Mansur Akhmad
Published: December 2024

Previous research on patients, families and communities has discussed the perception of mental illness and how stigma has a very constant impact on every aspect of the lives of individuals with mental illness. However, this issue has not been studied in the Malaysian context until now. The purpose of this study is to explore the perceptions and experiences that mental health patients with stigma have in Malaysia, as well as how it affects their daily lives. This qualitative research was conducted in Kuala Lumpur using semi-structured interviews with eight university students (three males and five females) undergoing outpatient treatment. Informants were selected using the snowball method, and with diagnoses that included depression, anxiety, eating disorders, bipolar disorder, and schizophrenia. Qualitative thematic analysis was used to identify themes regarding patients’ experiences of stigmatization, negative impacts, and solutions to overcome them. The results showed that social stigma is caused by the social environment, particularly through relationships with family and friends, potentially placing patients in a more intrusive environment, which reduces the level of support available during recovery. The study concluded that for those with mental illness, stigma is a pervasive landmine that they face daily through hurtful comments or jokes.
OPTIMIZATION METHODS FOR PARAMETER IDENTIFICATION MODEL OF TEST ELECTRORETINOSIGNAL TO ASSESS NEUROTOXICITY RISKS
Authors: Tymkiv Pavlo , Tkachuk Roman , Yanenko Oleksiy
Published: December 2024

Introduction. The development of advanced optimization methods plays a crucial role in the enhancement of diagnostic tools in the biomedical field, particularly in the analysis of complex physiological signals. Electroretinography (ERG) is a widely used diagnostic technique that records electrical responses generated by the retina in response to light stimuli, providing valuable insights into the functional health of retinal cells. ERG is instrumental in diagnosing conditions such as retinitis pigmentosa, diabetic retinopathy, and neurotoxicity. However, the analysis of low-intensity electroretinograms (ERG) presents numerous challenges, particularly due to noise and signal distortion, which complicate accurate signal interpretation.
Main purpose of this study.This paper is dedicated to developing an expert system for real-time analysis of electroretinographic signals (ERS), focusing on optimizing the parameters of a mathematical model for ERS analysis in conditions where noise and other distortions are present. The primary aim is to improve the accuracy and efficiency of ERG data processing, enabling early detection of neurotoxicity and other retinal conditions. To achieve this, we applied advanced optimization techniques, such as the Nelder-Mead method, known for its effectiveness in handling non-smooth, noisy functions.
Conclusions. 1. The application of the Nelder-Mead algorithm for optimizing the complex and noisy ERS model significantly improved the performance of ERG data analysis. The algorithm's adaptability to varying optimization conditions allowed for more accurate model parameter determination, particularly in the context of real-time neurotoxicity detection.

Reduction in Processing Time: The time complexity analysis revealed that the Nelder-Mead method reduced the time required to compute the model coefficients by approximately 15%. This improvement was achieved while maintaining the necessary precision for reproducing the test electroretinosignal, making it suitable for real-time applications.
Computational Efficiency: One of the key findings of this study is that the use of the Nelder-Mead algorithm reduced the computational load by up to 30%. This makes the method feasible for use in expert systems designed for real-time ERS analysis, allowing for the monitoring of functional changes in the retina during the early stages of neurotoxicity detection.
ANALYSIS OF THE FUNCTIONAL POSSIBILITIES OF AUTOMATED DOSING SYSTEMS FOR FINISHED MEDICINES
Authors: Shaleva Volodymyr , Matiko Fedir
Published: December 2024

In many modern productions, it is necessary to implement the process of dosing certain materials, liquids, reagents, etc. When automating such lines, the parameters of the dosing process can be very important. For example, in automated lines for dosing liquids into containers, the dosing process determines the efficiency of the entire production.
The dosing process is essential in producing finished medicines (FM). Particularly, the advantages and disadvantages of methods of vacuum, syringe, weight dosing of finished medicines, and dosing with the use of flow meters were analyzed. A dosing machine for FM is one of the components of finished medicines production. Therefore, the overall productivity of the production facilities depends on the dosing parameters, particularly the accuracy and time of filling the container. The quantitative output of the produced products will depend on the accuracy of dosing, which affects the economic indicators of the enterprise.
In this paper, the authors have analyzed the dosing methods, features of the dosing process and automated FM dosing systems. Based on the analysis, we proposed a weight dosing method for dosing pharmaceutical solutions into vials with 100 - 300 ml volume. It has been established that this method has many advantages, particularly high dosing accuracy, relatively low cost of implementation, and high equipment productivity. We carried out an analysis of the stages of the dosing process using the weight-filling method and proposed to develop an algorithm for choosing the duration of each stage based on the criteria of achieving the minimum filling time and the minimum filling error. We also proposed implementing an adaptive control algorithm with self-learning elements based on previous dosing cycles to control the dosing process. The proposed algorithm aims to optimize the dosing process parameters and achieve the best possible quality indicators, namely high dosing accuracy and minimum dosing time.

Published: December 2024

Energy resources accounting is a component of their rational consumption. The outdated equipment use that doesnot meet the requirements for measurement accuracy is one of the main issues in natural gas metering. Therefore, theissues of creating high-precision gas metering systems remain relevant. Gas metering units are used at various sites,from boiler houses to gas distribution stations and points that have different requirements for metrologicalperformances and characterized by different operating conditions.To improve the gas metering quality, it is necessary to control its physical and chemical parameters, such aspressure, temperature, density, gas composition, etc. Therefore, the creation of systems for measuring the flow andquantity of natural gas requires an integrated approach that includes recording, processing and monitoring allnecessary parameters using data transmission technologies.The automated collection lack and information conversion from the measuring system components makes itimpossible to remotely monitor its state.The aim of the work is a comparative analysis of existing systems for measuring the flow and quantity of naturalgas, as well as the requirements’ formulation for an automated system for measuring its parameters.The functioning features of existing systems, their structure and technical performances are discussed in thearticle. An analysis of current approaches to energy carrier accounting has been conducted.Particular attention is paid to the requirements for algorithms for processing and converting information receivedfrom automated systems for measuring natural gas flow rate, in addition to bringing the gas volume to base conditionsand calculating the consumed energy quantity. General requirements for such systems, which contribute to increasing the accuracy and reliability of measurements, are formulated.The prospects for further work are to improve an algorithm for the interaction between the measurement system components.
