Authors: Podoksenov M.N. , Shpakova Yu.A.
Published: October 2024

An Excel workbook has been created to calculate the curvature tensor of fourdimensional Lie groups equipped with a leftinvariant Lorentzian metric. Application of the workbook showed that selfsimilar homogeneous Lorentzian manifolds of fourdimensional Lie groups equipped with leftinvariant Lorentzian metrics are not necessarily flat. Namely, among the previously found three selfsimilar homogeneous manifolds of the Lie group𝐻𝑠 × R+, only one is flat, and two are not flat. The only one up to isometry selfsimilar homogeneous manifold of the Lie group 𝑆𝐸(2) × R+ is flat.

The Possibility of Rehabilitation of Legal Entities in Criminal Proceedings
Authors:   Kuban State Agrarian University named after I.T. Trubilin, Kovaleva Anna V.
Published: October 2024

The article examines the issues surrounding the right to rehabilitation of legal entities in criminal proceedings and the feasibility of its implementation. A comparison is made between the rehabilitation of natural persons and legal entities. Both the classical (substantive, material) and formal (procedural) approaches to rehabilita-tion in criminal proceedings are considered. It is noted that viewing rehabilitation solely from the perspective of the substantive approach significantly narrows the full range of related actions, decisions, and legal relation-ships, focusing primarily on the question of innocence and, consequently, on correcting the mistake made by the state through its bodies authorized to carry out criminal prosecution. The presence of the criterion of inno-cence presents a challenge in relation to the rehabilitation of legal entities, as the terms “guilt”, “innocence”, and “culpability” in the criminal legal sense are inapplicable to them. The author concludes that a legal entity, being a kind of abstraction, cannot possess such qualities as consciousness and will inherent in a person as a being endowed with reason. However, the prosecution of individuals directly related to the activities of a legal entity can at least harm its business reputation. Innocence, in turn, opens up the possibility for their rehabilitation, and thus, the rehabilitation of legal entities should also be considered and addressed.

Authors: Sauceda Juan Pedro Campos , Soto Manuel Alejandro Uranga , Gutiérrez Ana Karen Hernández , Rubio Verónica Pérez , Heredia José Basilio , Rangel María Dolores Muy
Published: October 2024

Objective: This study aimed to design a thermal process for three Mexican bean products packaged on flexible retort pouches and to compare the changes in quality, proximate composition, and antioxidant activity. 
 
Method: Three Mexican bean products: “pork beans” (PB), refried beans (RB), and mixed beans (MB, 50% “pork beans” and 50% refried beans), were packaged in retort pouches and processed in a steam/air retort at temperature 122°C, pressure = 2.6 kg·cm-2, come-up time = 13.5 min and 40 min of process, under overpressure conditions. Additionally, nine samples of each bean product packaged in plastic containers of 500 mL were added from the manufacturer's regular hot-fill processing line to be analyzed as control tests. Parameters of quality in all the products were evaluated.
 
Research results and discussions: The Fo values were 13.2, 13.5, and 11.3 min for PB, RB, and MB, respectively. The beans thermally processed showed better protein, fiber, total phenolic, and essential minerals than traditional treatment, were viable, and did not need refrigerated storage.
 
Research implications: The study of thermal processes in heat-resistant pouches in three types of ready-to-eat beans is a healthy and nutritious food alternative.
 
Originality/Value: This study contributes to the development of sterilized foods safe by adjusting the temperature and process time to a Fo value that guarantees the destruction of Clostridium botulinum, with less impact on the final quality of the processed food.
Theoretical Mediation of Drivers and Practices to Enhance Circular Economy Capabilities in SMES: Overcoming Economic, Technological, Cultural, and Social Barriers
Authors: Molina-Morejón Victor-Manuel , Flores Oscar González , Gurrola Eyran Roberto Díaz
Published: October 2024

Objective: This study aims to use the theoretical mediation of drivers and practices to support SMEs in developing capabilities related to the circular economy (CE). Through this, it seeks to overcome economic, technological, cultural, and social barriers, generating environmental and financial benefits.
 
Theoretical Framework: Circular economy (CE) theory highlights the need for multidisciplinary approaches to address barriers. These barriers, including economic, technological, social, and cultural challenges, hinder CE adoption, particularly in SMEs. Overcoming such obstacles requires innovative solutions, collaboration with green suppliers, and advanced recycling technologies. Practices like circular design, eco-efficiency, and education are critical in driving CE capability. Moreover, mediating variables, such as drivers in circularity and sustainability-focused education, facilitate the transition to CE, creating economic opportunities and fostering sustainable development across different industries.
 
Design/Methodology/Approach: The methodology combines qualitative and quantitative research using PLS-SEM. An analysis of six hypotheses was conducted with questionnaires applied to 280 companies, obtaining 124 responses. This innovative approach demonstrates the impact of theoretical mediation between barriers and circular economy capability (CEC), validating five of the six hypotheses.
 
Results: The key role of mediation in overcoming barriers to the CE is highlighted. Although the direct relationship between cultural and social barriers and the CEC was not validated, the intervention of the mediator construct allowed validation. Additionally, the predictive model is strengthened with indicators such as Q2 and VAF (Variance Accounted For), showing that SMEs can improve their CE capability by overcoming key barriers.
 
Research Limitations/Implications: In Mexico, SMEs lack a detailed analysis of their economic impact and face obstacles to adopting CE. The described methodology can be replicated in other contexts to facilitate the transition to a circular economy.
 
Originality/Value: The novel methodology offers a way to overcome barriers to the circular economy and promote a sustainable organizational culture in SMEs. It can be said that the strategy of this study was to achieve circular economy capability (CEC), with the mediating effect serving as the key tactic.

Detection of Volcanic Ash Using Goes-16 Satellite Imagery: Case Study of Popocatépetl Volcano, Mexico
Authors: Juárez Santiago Piñón , Ramírez-Serrato Nelly L. , Valade Sébastien
Published: October 2024

Objective: The objective of this study is to investigate the accuracy of volcanic ash detection using satellite imagery, to improve existing monitoring tools to adapt them to the Popocatépetl volcano in Mexico.
 
Theoretical Framework: Volcanic ash detection via remote sensing employs Pavolonis' algorithms that compare radiances in the thermal and mid-infrared spectrum. This approach differentiates ash from clouds and water vapor by leveraging its differential absorption. Satellites such as GOES-16, which capture multispectral data, optimize the continuous detection and monitoring of ash dispersion, even in areas of low concentration.
 
Method: Three volcanic ash detection algorithms were compared using images from the Popocatépetl eruption event on May 21, 2023: two developed by Pavolonis, which combine thermal and mid-infrared bands, and a third, a spectral adaptation designed to enhance precision at the edges of the ash cloud, tailored to the study area. Results were validated with an RGB ash image provided by NOAA.
 
Results and Discussion: Pavolonis' algorithms provided a solid foundation for general detection, but the third algorithm, specifically designed for this study, significantly improved edge detection where classification conditions are more complex. This improvement was reflected in a higher agreement with the RGB ash image used as a reference. However, limitations related to atmospheric interference were identified, which require further adjustments in low ash concentration scenarios.
 
Research Implications: The findings of this research have significant practical and theoretical implications for volcanic risk management and environmental protection. Enhanced accuracy in volcanic ash detection can optimize monitoring and early warning strategies, reducing risks to public health and infrastructure.
 
Originality/Value: This study contributes to the literature by introducing a specific spectral adaptation to improve edge detection of volcanic ash, a novel approach not previously addressed. The research's relevance lies in its ability to refine monitoring methodology, providing more effective tools for volcanic risk management and offering a model applicable to other areas facing similar remote sensing challenges.

Authors: Alves Daniela Maria , Souza Luciana Cristina de , Santos Tamires de Paula dos , Begnini Mauro Luiz , Capuci Ana Paula Silva
Published: October 2024

Objectives: This study aims to determine the solubility of amoxicillin trihydrate hydrochloride in water at different temperatures, addressing the scarcity of solubility data for this substance in the literature. The research focuses on the solubility behavior of the semi-synthetic antibiotic, part of the β-lactam group, widely used orally.
 
Theoretical Framework: Amoxicillin is a β-lactam antibiotic of great therapeutic importance. Its solubility is relevant to the effectiveness of oral formulations and varies according to temperature. The literature on the solubility equilibrium of this compound is limited, motivating new studies that assist in the development of pharmaceutical solutions and the understanding of its physicochemical properties.
 
Method: The solubility of amoxicillin trihydrate hydrochloride was determined at three temperatures: 298.15 K, 309.15 K, and 318.15 K, using the UV spectrophotometry method. The experiment involved 3 hours of stirring and 2 hours of decantation, with a 1 mL aliquot taken for analysis. The samples were diluted in 100 mL volumetric flasks and analyzed by spectrophotometer.
 
Results and Discussion: The experimental results allowed correlating the solubility of amoxicillin trihydrate hydrochloride with empirical equations from the literature. The solubilities obtained demonstrated precision, with low relative deviation between the experimental values and those calculated by the equations. This indicates that the empirical models are adequate for predicting solubility behavior at different temperatures.
 
Research Implications: The research contributes to enriching the solubility database of antibiotics, essential for drug formulation and the development of new therapeutic applications. The precision of the experimental data supports future studies in the field of pharmacology and chemical engineering, particularly in the context of solid and liquid formulations.
 
Originality/Value: The study is original in addressing the solubility of amoxicillin trihydrate hydrochloride in water at different temperatures, filling a gap in the literature. Additionally, the use of UV spectrophotometry and the correlation of the data with empirical equations reinforce the validity of the results, making it valuable for researchers and professionals in the pharmaceutical sector.
Digital Mini-Archives: Social Media Users as Curators of an Architectural Utopia
Authors: Tošić Jovana
Published: October 2024

This paper explores the importance and meaning of a new concept of architectural archives – digital mini-archives in the form of social media profiles (Instagram profiles), whether they are public or private. The paper's interpretation of digital architectural archives is based on Jacques Derrida's interpretation of archives. The aim is to analyze the relationship between archivists and users in the context of social media platforms, and the structure and content of digital mini-archives. I tried to select examples of different Instagram profiles whose content (photos, videos, and quotes) relates to architectural history and architectural design presented in an innovative manner. The hypothesis emphasizes a curating role of social media users as interpreters of architectural history references and their (new) meanings, as well as curators of the future of architecture. Also, the concept of architectural utopia concerns Nathaniel Coleman's theory of utopia in architecture and its contemporary interpretations. There is a strong bond between architectural utopia and digital mini-archives which enable architecture's utopian potential because of their flexibility, openness to change, and transformability. Thus, experimental projects with utopian potential are created based on digital mini-archives. However, do these digital mini-archives contribute by deciding which (part of) architectural history ought to be forgotten or remembered in collective memory and translated to another temporal context through experimental architectural design?
Cultural Therapy and Concern for the Archive. The Case of Documentary Video Archives by Tomáš Rafa
Authors: Grúň Daniel
Published: October 2024

In this paper, the author explores current perspectives on contemporary art projects through the concept of the archive. By applying a theoretical framework termed “concern for the archive”, the author aims to elucidate complex relationships between the archive as a medium and the situated practices of contemporary art. The paper examines contemporary art as a form of temporary memory storage, particularly through the analysis of Tomáš Rafa’s documentary films. It addresses two key questions: What specific aspects of concern for the archive can be identified in political or activist contemporary art? How does concern for the archive differ from archival care, and why is this distinction important?
In the first section, the author discusses the “zones of contact” in political activist art, highlighting the formation of dialogical structures and distinguishing them from scientific research and purely documentary creation. The second section traces the layers of artistic training in Grzegorz Kowalski's renowned studio at the Academy of Fine Arts in Warsaw, where the author gained experience in organizing and documenting collective workshops. This part reveals the specifics of documentary video creation with its activist and archival overlaps.
In the final sections, the author outlines a theoretical framework for interpreting documentary video pieces in relation to the concepts of archive, cultural trauma, and cultural therapy.
“Different New Music in Yugoslavia”: The Earliest Minimalist Manifestations
Authors: Emmery Laura , Miladinović Prica Ivana
Published: October 2024

Some of Yugoslavia’s most radical musical manifestations unfolded during the 1970s and 1980s. Aided by postwar Yugoslav cultural programs, the iconic Student Cultural Center (SKC) in Belgrade – a student-managed “safe space” for free expression and creativity – opened its doors in 1971 and instantly became a magnet for experimental musicians throughout the Western and Eastern Blocs. A group of rebellious composers and performers – Opus 4 and the Ensemble for Different New Music made some of the largest strides in Yugoslav music history and defined a new era of avant-garde and a unique brand of minimalism, influenced by performance and conceptual art, Cage-style experimentalism, Fluxus, and the use of multimedia. This study briefly illustrates their robust vision that connected the East with the West in a fruitful exchange of ideas, despite the geo-political division of the world at the time.
“Anti-monument: The Way to a Forgotten Historical Event”. Participation as a Tactics for Creating New Memory
Authors: Kulunčić Andreja
Published: October 2024

In this text, I will address historical memory as an ethical obligation and a means of intervening in the process of social change, with a particular emphasis on the problem of excluding women from main historical narratives. My analysis is set in relation to the marginalized historical episode of the political camp for women in Goli Otok and Sveti Grgur. I will explore how tactics of socially engaged artistic practice can effectively bring this forgotten historical episode into public focus and integrate it into institutional frameworks. Special attention will be given to the concept of the anti-monument as an innovative critical approach to the memorialization practices of violent heritage. The anti-monument involves the public in the process of memory transmission, allowing everyone to seek information and respond according to their own interest, and by building their own memory, become carriers of memory, and take responsibility for the future.
For the purpose of this paper, I will refer to the case study “850 Women for 850 Women”, which I initiated and have been leading since 2021 within the artistic project “You Betrayed the Party Just When You Should Have Helped It”, as a concrete example of participatory building of a collective anti-monument and repositioning towards memory. This participatory practice indicates how artistic interventions can actively transfer memory from the past through present collective action into the future. The paper provides insight into ways artistic tactics establishes connection with marginalized histories and strengthens collective memories with the idea of historical justice and inclusion.

Based on nucleotide polymorphism of cpDNA intergenic spacers psbA-trnH, trnL-trnF, and trnS-trnG, we studied the genetic diversity and population structure of a mountain species Oxytropis vasskovskyi Jurtz., endemic to East Siberia. The populations were characterized by medium and high haplotype (0.524–1.000) and low nucleotide (0.0003–0.0008) diversity. Variability distribution analysis showed a moderate level of diff erentiation; the interpopulation component accounted for about 44% of the total genetic variation in O. vasskovskyi. We observed demographic expansion for three of fi ve O. vasskovskyi populations. The haplotypes of the fi ve studied populations form a single complex in the genealogical network, which is probably due to their common origin, relatively recent divergence and incomplete lineage sorting, as well as the existing gene exchange between populations. Thus, in four of the fi ve studied populations, a low level of nucleotide diversity and the absence of nucleotide substitutions were determined, which indicates the need to use certain measures to protect all known habitats, conduct regular monitoring of their state and search for new locations of the species.
The Effect of AI-Enabled Credit Scoring on Financial Inclusion: Evidence from an Underserved Population of over One Million
Authors: Li Chunxiao , Wang Hongchang , Jiang Songtao , Gu Bin
Published: October 2024

We studied the effect of a major bank adopting an AI-enabled credit scoring model on financial inclusion as measured by changes to the approval rate, default rate, and utilization level of a personal loan product for an underserved population. The bank serves over 50 million customers and previously used a traditional rule-based model to evaluate the default risk of each loan application. It recently developed an AI model with a higher prediction accuracy of default risk and used the AI model and the traditional model together to assess loan applications for one of its personal loan products. Although the AI model may be more accurate in estimating default risk, little is known about its impact on financial inclusion. We investigated this question using a difference-in-differences approach by comparing changes in financial inclusion of the personal loan product that adopted the AI model to that of a similar personal loan product that did not adopt the AI model. We found that the AI model enhanced financial inclusion for the underserved population by simultaneously increasing the approval rate and reducing the default rate. Further analysis attributed the enhancement in financial inclusion to the use of weak signals (i.e., data not conventionally used to evaluate creditworthiness) by the AI model and its sophisticated machine learning algorithms. Our findings are consistent with statistical discrimination theory, as the use of weak signals and sophisticated machine learning algorithms improves prediction accuracy at the individual level, thus reducing the reliance on group characteristics that often lead to financial exclusion. We elaborated on the development process of the AI model to illustrate how and why the AI model can better evaluate members of underserved populations. We also found the impacts of the AI model to be heterogeneous across subgroups, and those with missing weak signals saw smaller improvements in the approval rate. A simulation-based analysis showed that simplified AI models were also able to increase the approval rate and reduce the default rate for this population. Our findings provide rich theoretical and practical implications for social justice by documenting how an AI model designed for improving prediction accuracy can enhance financial inclusion.

The results of the study of the possibility of generating aerosols of different physicochemical composition by pulse methods using energy of high-energy substances are presented, which allow to release a large amount of energy over short periods of time. When dispersing liquid media by pulse methods, the mechanism of aerosol formation is extremely complex and characterized by a large number of parameters, which are determined by both the properties of the dispersed phase and the properties of the external medium. The article shows the devices of pulse sprayers and the characteristics of aerosols generated by them.

В работе рассмотрена математическая модель, описывающая течение ламинарной стационарной вязкой несжимаемой смеси газа в трехмерном осесимметричном канале. Математическая модель, описывающая этот процесс, состоит из уравнений Навье – Стокса, уравнения неразрывности, тепло- и массообмена, которые записаны в безразмерной форме с учетом осесимметричности в цилиндрической системе координат. Решение уравнений осуществляется в физических переменных «скорость – давление» на разнесенной разностной сетке. Показано влияние характерных параметров и критериев на распределение полей температуры. Полученная математическая модель позволяет проводить численные исследования по выбору оптимальных условий осуществления процесса.

The paper considers a mathematical model describing the flow of a laminar stationary viscous incompressible gas mixture in a three-dimensional axisymmetric channel. The mathematical model describing this process consists of the Navier - Stokes equations, the equations of continuity, heat and mass transfer, which are written in dimensionless form, taking into account axisymmetry in a cylindrical coordinate system. The equations are solved in physical variables "velocity - pressure" on a spaced difference grid. The influence of characteristic parameters and criteria on the distribution of the fields of temperature. The obtained mathematical model makes it possible to carry out numerical studies on the choice of optimal conditions for the process of reduction of tungsten hexafluoride with hydrogen.

Этилен является одним из сырьевых материалов в химической промышленности. Производство этилена считается жизненно важным символом национальной всесторонней силы в нефтехимической промышленности. Для увеличения экономического эффекта производства этилена необходимо внедрять системы усовершенствованного управления технологическим процессом (СУУТП), которые демонстрируют более оптимальные характеристики управления по сравнению с традиционным управлением процессом. В данной статье описывается совершенствование информационно-измерительной системы производства этиленовой продукции, заключающееся в определении коэффициента скорости проявления коксовых отложений в катализаторах. Цена ошибочных прогнозов состояния катализаторов гораздо выше, чем при неверной оценке активности. Очевидно, что необходимы надежные и обоснованные методы контроля состояния катализаторов. Поэтому в последнее время наряду с классическими способами определения качества каталитических контактов развиваются и методы обработки результатов тестирования с использованием математических моделей. Авторами предлагается отслеживать фактическое состояние катализатора с помощью генетического алгоритма.

Ethylene is one of the raw materials in the chemical industry. Ethylene production is considered a vital symbol of the nation's all-round strength in the petrochemical industry. To increase the economic effect of ethylene production, it is necessary to introduce advanced process control systems (SUPS), which demonstrate more optimal control characteristics compared to traditional process control. This article describes the improvement of the information-measuring system for the production of ethylene products, which consists in determining the coefficient of the rate of manifestation of coke deposits in catalysts. The cost of erroneous predictions of the state of catalysts is much higher than with an incorrect estimate of activity. It is obvious that reliable and valid methods for monitoring the catalyst condition are needed. Therefore, recently, along with the classical methods for determining the quality of catalytic contacts, methods for processing test results using mathematical models have been developing. The authors propose to track the actual state of the catalyst using a genetic algorithm.

Производство ацетилена окислительным пиролизом природного газа представляет собой сложную химико-технологическую систему. Одним из важнейших этапов, при создании этиленовой продукции, является гидрирование ацетилена в этан-этиленовой фракции (ЭЭФ). Для ускорения процесса гидрирования, в реакторах применяют катализаторы. Как и во многих технологических процессах при гидрировании образуются побочные продукты реакции, снижающие эффективность катализаторов, ускоряющие их закоксованность. Рассматривается вопрос закоксованности катализатора. Предложен вариант усовершенствованный системы управления, при котором на основе анализа данных с датчиков, используемых для контроля технологического процесса в реакторе, будет отслеживать фактическое состояние закоксованности катализатора. В качестве основополагающего инструмента, предлагается использовать генетический алгоритм. С помощью генетического алгоритма, появляется возможность определить коэффициент скорости проявления коксовых отложений. Предлагаемый вариант позволит избежать плановых остановок процесса и улучшить экономическую составляющую рассматриваемого оборудования.

Acetylene production by oxidative pyrolysis of natural gas is a complex chemical-technological system. One of the most important stages in the creation of ethylene products is the hydrogenation of acetylene in the ethane-ethylene fraction (EEF). To accelerate the hydrogenation process, catalysts are used in the reactors. As in many technological processes, hydrogenation produces by-products of the reaction, which reduce the efficiency of catalysts and accelerate their coking. The question of catalyst coking is considered. A variant of an improved control system is proposed, in which, based on the analysis of data from sensors used to control the technological process in the reactor, the actual state of coking of the catalyst will be monitored. It is proposed to use a genetic algorithm as a fundamental tool. With the help of a genetic algorithm, it becomes possible to determine the rate of development of coke deposits. The proposed option will allow avoiding planned process shutdowns and improving the economic component of the equipment under consideration.
