Published: December 2024

High blood sugar levels in DM can inhibit wound healing and increase the risk of infection. Diabetic ulcer therapy with commercial anti-inflammatory drugs is relatively expensive and has side effects. VCO and diamond leaf extract have the potential as an alternative therapy with anti-inflammatory effects, but further research is needed regarding the right dose. This study aimed to analyze the impact of VCO administration with supplementation of diamond leaf extract (Azadirachta indica L.) on IL-6 levels in wound healing of type 2 DM model rats. This research is a true experimental research with a post-test-only control group design. This study used 25 male mice which were divided into five groups, namely: group P1 5% Intaran leaf extract, P2 10% Intaran leaf extract, P3 15% Intaran leaf extract, negative control (NaCl 0.9%), and positive control (Povidone Iodine). Data were analyzed using the Shapiro-Wilk statistical test, followed by the One-Way Anova test, the confirmation test, and the LSD test. The results showed a significant difference in IL-6 levels between the treatment groups, as evidenced by the One Way ANOVA statistical test results. Considerable value was obtained in the test of IL-6 levels on day 4 Sig. 0.003 and day 14 Sig. 0,046. It can be concluded that the treatment group giving VCO supplementation with intern leaf extract at a concentration of 10% affects wound healing with a decrease in IL-6 levels on day 14. This study provides an important contribution to DM wound healing efforts by using affordable natural ingredients with low potential side effects.

Published: December 2024

Erectile dysfunction (ED) is a common condition marked by difficulty maintaining a penile erection, often linked to reduced nitric oxide (NO) production. This study investigates the aphrodisiac properties of ethanolic white ginger extract (Z. officinale Rosc. var. officinarum) in male Wistar rats. Sixteen male and sixteen female rats were divided into four groups: two groups received 25% and 50% ginger extract, one served as a negative control, and the other as a positive control using sildenafil. Ginger rhizomes were dried, powdered, and extracted with ethanol. Phytochemical analysis revealed alkaloids, flavonoids, tannins, saponins, and terpenoids. Behavioral parameters, including introduction (approach to females), climbing, and coitus, were observed to evaluate sexual activity. The group treated with 50% ginger extract showed the highest frequency of introduction and climbing, while the sildenafil group exhibited the highest coitus frequency. Statistical analysis using the Kruskal-Wallis test indicated significant differences in sexual behavior across the groups. The study suggests that white ginger extract, especially at higher concentrations, may have aphrodisiac effects by enhancing sexual behavior in male rats. This could be due to its bioactive compounds affecting hormone levels or the nervous system. The findings propose white ginger as a potential natural treatment for ED, with further research required to explore its implications in humans.

Published: December 2024

The toxicity levels of heavy metals accumulated in water and sediment due to hospital waste discharge not only impact the environment but also pose a significant threat to human health. Long-term accumulation of these metals in the body may lead to degenerative diseases such as cancer. This concern highlights the urgency of conducting laboratory-based experimental research to identify the distribution of heavy metals in aquatic environments caused by hospital waste. The study employs Nile tilapia (Oreochromis Niloticus) as a bioindicator, a species capable of absorbing metals through its tissues. The research subjects consisted of 35 Nile tilapia with a body length of 8–12 cm and a weight of 12–15 grams, alongside hospital waste samples collected from three discharge points. Data collection methods included sample preparation of both hospital waste and Nile tilapia, treatment with varying concentrations of lead nitrate (Pb(NO3)2), and maintenance durations of 7, 14, 21, and 28 days. The concentration of Pb in the gills and muscle tissue of the fish was measured using Atomic Absorption Spectroscopy (AAS). The analytical data, represented as heavy metal concentrations, were plotted on a graph showing the relationship between concentration variations and maintenance durations and analyzed using One-Way ANOVA with nonparametric Tukey's test. The analysis revealed that the highest Pb concentration was observed in the gills of Nile tilapia on day 28 at 1.57 ppm, while the Pb concentration in muscle tissue reached 0.25 ppm on day 21. According to BPOM standards, Pb levels in Nile tilapia muscle tissue remain within the safe consumption threshold (≤0.3 ppm), whereas Pb levels in the gills exceeded the tolerance limit. This study provides scientific evidence on the risks of heavy metal accumulation in aquatic biota due to hospital waste and underscores the importance of improved waste management practices to safeguard public health and the environment.
STUDY OF THE CUTTING FORCE BASED ON THE OBTAINED UNDEFORMED CHIPS DURING CUT IN WHEN MACHINING AN INTERNAL GEAR BY POWER SKIVING METHOD
Authors:   Department of Robotics and Integrated Mechanical Engineering Technologies, Lviv Polytechnic National University, Slipchuk Andrii
Published: December 2024

This article explores the formation of non-deformed chips during the cut-in of an internal toothed ring using the Power Skiving method. This pivotal stage of the cutting process poses significant hazards not only in gear cutting but also in any cutting operation. The study involved modeling the process at the initial stage for various technological parameters, including cut-in depth and number of working passes. To achieve non-deformed chips, a methodology developed for worm milling was applied. The developed simulation can calculate the corresponding geometry of the cut on each rotation of the cutting tool into the workpiece. Through the utilization of a CAD/CAM environment, solid models involved in the process accurately replicate the cutting process. Based on the obtained regularities, it is possible to select optimal technological parameters and establish safe cutting modes for different gears for the respective equipment and its power parameter
Estimation of Stresses in a Plate with a Concentrator through Ultrasonic Measurements of Acoustic Anisotropy
Authors: Tretyakov D. A. , Osovik D. S.
Published: December 2024

Introduction. Acoustic anisotropy is measured during ultrasonic nondestructive testing. It estimates the magnitude of stresses by the acoustoelasticity method. The literature describes in detail the application of this approach in the case of a biaxial strength of extended structures: main pipelines, rail strings, steam generators, and others. They assume the presence of a uniform field with zero or weak gradients of stresses and deformations. However, the problem of timely detection and assessment of critical stresses caused by local concentrators through ultrasonic testing has not been solved. The presented material is intended to fill this gap. The work is aimed at determining the possibilities of the acoustoelasticity method to estimate the difference in the main biaxial stresses around the concentrator — a circular cutout in a rectangular plate.Materials and Methods. A 510×120×15 mm plate with a central hole of 40 mm in diameter was cut from a sheet of commercial-purity aluminum of the AMc brand (AW-3003 according to ISO) across the rolling direction, and subjected to uniaxial step loading in an Instron-8850 testing machine. For ultrasonic measurements, an acoustic sensor with a carrier frequency of 5 MHz was used. The stresses were calculated by solving the problem of stretching an isotropic linear-elastic plate in the ANSYS finite element modeling package and by the relations of the plane Kirsch problem obtained in the polar coordinate system.Results. The research allows us to state that the results of analytical and numerical calculations largely coincide only for points located near the zone of greatest stress concentration. In all other cases, the indicators differ several times in sign and modulus. The difference is explained by the fact that Kirsch's approach assumes the action of compressive stresses in the area of location of some points, but this factor is absent if we are talking about a real plate. It has been established that in the area of material with predominant tensile stresses, the acoustoelasticity method allows for a quantitative estimate of their difference with an error not exceeding the engineering one. Calculations based on the Kirsch relations correlate with the others only at points with the maximum concentration of tensile stresses.Discussion and Conclusion. The results of the study provide applying the acoustoelasticity method to estimate the magnitude of tensile biaxial stresses in the area around the fabrication holes. They are consistent with well-known scientific results and make it possible to rationally select the measurement points of acoustic anisotropy. The results of this scientific work can be applied in ultrasonic non-destructive testing using the acoustoelasticity method.
Investigation of Parameters Influencing the Establishment of Hydrostatic Mode in the Crosshead-Guide Assembly of High-Pressure Plunger Pump
Authors: Korchagina M. V. , Stepanov V. N. , Kireev S. O. , Lebedev A. R.
Published: December 2024

Introduction. When applying hydraulic fracturing technology to increase the efficiency of formation fluids, high-pressure pumps with a crosshead drive assembly are used. The major problem in the operation of these pumps is the wear of the crosshead guides. The crosshead is a flat sliding friction pair, leading to wear of the plunger seals and a decrease in the basic pump performance indicators. To solve this problem, it was previously proposed to use new materials and antifriction coatings, original designs of friction units, etc. However, a detailed description and solution to the problem under consideration has not been found in the literature at present. The objective of this study is to determine, under maximum load, the influence of the unit design, process temperature and pressure in the lubrication system on the values of the parameters that provide for the hydrostatic mode for a flat thrust bearing in a crosshead-guide unit of a high-pressure plunger pump.Materials and Methods. The parameters were determined by the simulation technique using modal analysis applicable in the case of high dynamic loads acting on the studied unit. The calculation of the hydrodynamic parameters of the lubricating layer was based on the combination of the Reynolds model and the Stokes model in numerical modeling. The study was conducted using a calculation model representing a section of a plunger pump, considered as “flexible bodies” model, in the field of gravity forces. The mathematical dependences of the parameters under consideration were presented in the form of regression equations obtained from the results of a numerical experiment.Results. The maximum load on the lower crosshead guide was determined, for which further hydrodynamic studies were conducted. Factors influencing the process were studied — gaps filled with lubricant (depending on the design of the unit), temperature, and pressure in the lubrication system. Mathematical dependences of the influence of the considered factors on the values of the parameters determining the establishment of the hydrostatic mode were obtained.Discussion and Conclusion. The obtained mathematical models show the degree and influence of the factors under consideration on the studied parameters of the hydrostatic lubrication mode of the unit — the force acting on the crosshead from the lubricating layer, and the mass flow rate of the lubricant at the outlet of the system. It is found that the greatest influence is exerted by the change in the volume of gaps filled with lubricant, the mass flow rate of lubricant at the entrance to the system, which simulates the increase in pressure in the lubrication system of the friction unit. The results obtained do not contradict the conclusions reached in works on similar topics, and can be used in further research.
Политика коренизации на Северном Кавказе: достижения и противоречия. 1920-1930-е гг.
Authors: Турпалов Лема
Published: December 2024

В статье предпринята попытка раскрыть особенности реализации в национальных регионах Северного Кавказа большевистской программы коренизации в годы формирования советского режима на основе критического осмысления изданной научной литературы, изучения архивных материалов, контент-анализа региональных газет и журналов. На различных этапах процесса коммунистического перевоспитания горского населения национальная политика ВКП(б) претерпевала существенные изменения, порой ее векторы менялись на противоположные и не были вызваны объективными причинами. Между тем природа этих изменений все еще малоисследованы, а некоторые аспекты вообще остаются вне поле зрения историков. Назрела необходимость в переосмыслении положений и выводов научных разработок недавнего советского прошлого и современных публикаций.
Institutional shareholders as moderators: Uncovering the link between accounting information and sustainability in Thailand, Malaysia, and Singapore
Authors: Tangruenrat Chanchai , Boonyanet Wachira
Published: December 2024

This study seeks to explore the information value of financial metrics on corporate sustainability and investigate the moderating effects of institutional shareholders on the association between net cashflows (NCF) and corporate sustainability of the leading ASEAN countries. The dataset consists of companies listed on the Stock Exchange of Thailand, Malaysia and Singapore during 2013–2023. Fixed effects panel regression is executed in this study. Subsequently, the conditional effects served to evaluate the influence of institutional shareholders on the association between NCF and corporate sustainability. This study employs agency theory to explore how the alignment of institutional shareholders influences sustainability outcomes. This study found that institutional shareholders themselves supply information for the sustainability indicator in Thailand and Singapore, but not in Malaysia. Furthermore, adversely correlated with sustainability metrics in all three nations is the interaction term between institutional shareholders and net cashflows. Further investigation reveals that for each nation’s sustainability measures the institutional shareholders offer value relevant to net cashflows at certain amounts. This study not only contributes to existing academic research on sustainability and financial indicators, it also provides practical strategies for companies and investors trying to match financial performance with sustainability goals in a fast-changing global market.
The impact of ESG components on brand value
Authors: Takács András
Published: December 2024

In recent years, environmental, social and governance (ESG) issues have emerged as a significant area of focus for companies. Furthermore, the international trend is reinforced by the emergence of relevant regulations and the obligation to prepare sustainability reports in leading economies and in the European Union. The impact of ESG and its constituent elements (environmental, social, and governance) on financial performance has been the subject of extensive investigation, with the majority of studies documenting a positive correlation. This evidence substantiates the assertion that sustainability initiatives can yield financial benefits. Concurrently, research has accorded much less attention to the impact of ESG performance on brand value, which can be identified as an indicator of consumer perception. This study, based on data from 26 global corporations between 2012 and 2021, demonstrates that efforts in the areas of environmental and social responsibility have a positive impact on consumer perception, which translates into increased brand value. Nevertheless, such a relationship was not found in case of the governance component.

Authors: Puriningsih Feronika Sekar , Ramli Muhammad Isran , Ali M. Saleh , Malisan Johny
Published: December 2024

This research investigates the safety status of water transport in Lake Towuti, South Sulawesi, employing the MICMAC and MACTOR methodologies to discern the factors that affect navigation safety and the interactions among the relevant stakeholders. The MICMAC analysis reveals that the effectiveness of sustainable transportation in Lake Towuti is significantly dependent on technical elements such as vessel certification, maintenance practices, and safety monitoring, alongside robust relationships among key entities like The South Sulawesi Class II Land Transportation Management Center (BPTD), The East Luwu District Transportation Office (Dishub), and the Timampu Port Service Unit (Satpel). When implementing the MICMAC-MACTOR model, it is essential to consider the technical implications of the proposed recommendations from the perspectives of social justice, environmental sustainability, and economic feasibility. The outcomes derived from the MICMAC and MACTOR assessments in Lake Towuti provide critical insights that can be utilized in other lakes across Indonesia, especially those that exhibit deficiencies in safety measures and adherence to inland water transport safety regulations.
Water quality and palm oil mill effluents—Analysis of the effect of palm oil mill effluents (POME) on consumption of bore-hole water in Nigeria
Authors: Effiong Mfonobong Okokon
Published: December 2024

Nigeria’s palm oil processing industry poses significant environmental pollution risks, jeopardizing the country’s ability to meet the UN’s 17 Sustainable Development Goals (SDGs) by 2030. Traditional processing methods generate palm oil mill effluent (POME), contaminating soil and shallow wells. This study investigated water samples from five locations (Edo, Akwa-Ibom, Cross River, Delta, and Imo states) with high effluent release. While some parameters met international and national standards (WHO guidelines, ASCE, NIS, and NSDWQ) others exceeded acceptable limits, detrimental to improved water quality. Results showed, pH values within acceptable ranges (6.5–8.5), high total conductivity and salinity (800–1150 µS/cm), acceptable hardness values (200–300 mg/L), nitrite concentrations (10–45 mg/L), excessive magnesium absorption (> 50 mg/L), biochemical oxygen demand (BOD) indicating significant pollution (75–290 mg/L), total dissolved solids (TDS) exceeding safe limits in four locations, total solids (TS) exceeding allowable limits for drinking water (310–845 mg/L), water quality index (WQI) values ranged from “poor” to “very poor”. POME contamination by metals like magnesium, nitrite, chloride, and sodium compromised shallow well water quality. Correlation analysis confirmed robust results, indicating strong positive correlations between conductivity and TDS (r = 0.85, p < 0.01) and pH and total hardness (r = 0.65, p < 0.05). The study emphasizes the need for environmentally friendly palm oil processing methods to mitigate pollution, ensure safe drinking water, and achieve Nigeria’s SDGs. Implementation of sustainable practices is crucial to protect public health and the environment.
Analyzing the Dry Sliding Wear Performance on Aluminum 6061 Alloy Reinforced with SIC And B₄C Hybrid Nanocomposite
Authors: Elil Raja D. , Vijayan S. , Sonar Tushar , Prathap Singh S.
Published: December 2024

The methodology of enhancing the wear resistance of hybrid Metal Matrix Composites (MMCs) involves reinforcing the metal or alloy with robust materials. This study focuses on the manufacturing of a hybrid nanocomposite, which includes 0.6 vol.% of Silicon Carbide (SiC) and 0.2 vol.% of Boron Carbide (B₄C) nanoparticles with aluminum (Al) 6061 alloy. This is achieved through an ultrasonic assisted stir casting methodology, and a pin-on-disc tribometer is used to investigate the sliding wear rate and Coefficient of Friction (COF). Vicker's microhardness tester evaluated the microhardness of the nanocomposite, revealing it to be 18% harder than the Al 6061 alloy. Further, the metallurgical examination done through Hi-Resolution Scanning Electron Microscope (HRSEM) and X-ray diffraction (XRD) techniques confirmed the existence of SiC and B₄C nanoparticles. The wear experiment was done under diverse input wear experiment variables such as applied load, sliding velocity, and sliding distance, and optimization was done through Taguchi’s technique. Applied load contributed 40.9% to wear rate, and increasing load increased wear rate due to higher pin-counter disc contact pressure. Sliding speed contributed 42.18% to the COF, while increasing it decreased it due to lower pin-disc contact. The worn area inspection revealed an abrasive wear mechanism with substantial surface degradation at higher loads. The study may progress science and develop stronger materials for many purposes.
Behavioural mimicry or herd behaviour of Generation Z? Social media interactions in the context of information overload
Authors: Stepaniuk Krzysztof , Lăzăroiu George , Misiewicz Chrystyna , Pereira Verónica Crespo
Published: December 2024

The article aimed to examine the relationship between Generation Z’s interactions on social networking sites in the context of herd behaviour and behavioural mimicry through central and peripheral content processing pathways. The study was conducted using the CAWI method on a group of 142 representatives of Generation Z from selected universities in Poland. Nonparametric tests were used for statistical analyses. In the case of information overload, approximately 20 % of respondents’ interactions on different social media platforms may result from behavioural mimicry and herd behaviours. This type of activity is influenced primarily by the observed number of interactions and the emotional nature of other users’ reactions. The observed differences are determined by gender, the type of social media platform, and related content specificity. Research limitations result from the specificity of the research sample in the context of its homogeneity and size. The theoretical contribution is related to the development of the cognitive-emotional-behavioural theory of memes about the imitation of interactions of social media users’ conditioned herd behaviour and behavioural mimicry. The novelty of the research lies in the application of the theoretical Elaboration Likelihood Model approach to the analysis of herd behaviour and behavioural mimicry in the context of research on the cognitive, emotional, and behavioural activities of various social media platform users.

The article aims to analyse AI’s use for optimising management processes in urban waste incineration plants, making them consistent with the implementation of the sustainable development goals SDG #11 and SDG #12. The triangulation of research methods was chosen to achieve the most reliable research outcomes. The case study was the selected qualitative method. Among the available techniques, two were selected: Computer-Assisted Web Interviewing (CAWI) and in-depth interviews, both of which were employed to gather the necessary data. Scientific research analysed the AI-based technologies used by individual incinerators. The analysis encompassed trends in waste incineration plants utilising AI for sustainable development in smart cities, particularly for achieving SDG#11 and SDG#12, focusing on leveraging AI to enhance environmental outcomes. The effect of using AI in municipal waste incineration plants for SDG#11 and SDG#12 can be applied to other entities implementing the principles of sustainable development in smart cities. The identified trends underscore the importance of adopting and implementing integrated policies and plans that address inclusion, resource efficiency, climate change mitigation and adaptation.

Corruption remains a perennial problem in Eastern Europe, especially in countries that have a socialist influence. This study examines the drivers, the effects on economic growth, and the measures that governments take to address this vice in these economies. Considering the empirical evidence and case studies from Bulgaria, Romania, and Hungary, this study finds that factors that have led to tax evasion are archaic taxation systems, high taxes, and inefficiency in the administrative systems. Descriptive and inferential statistics show that high taxes and unemployment have a positive relationship with tax evasion while GDP has a negative non-significant relationship. There is a decrease in government revenue which implies that fewer services will be provided to the public and increased social and economic disparity. Previous approaches to combating evasion include the simplification of the tax code and better enforcement, which have produced only limited success. The study also recommends that governments should broaden the policies to enhance the efficiency of the tax system by simplifying it, improving the mechanisms of compliance, and creating an investment-friendly environment. Thus, this research provides a historical and economic analysis of tax evasion and its impact on transitional economies and provides recommendations for how to reduce the effects of tax evasion on development. These results are valuable for policymakers who intend to improve fiscal sustainability and economic development in the Eastern European region.
Deconstructing Digital Transformation: A Multidimensional Analysis of Digital Literacy’s Role in Shaping Human Capital and Driving Organizational Success

Published: December 2024

This study presents a comprehensive investigation into the multifaceted relationship between digital literacy, human capital development, and organizational performance in the context of digital transformation. Through a rigorous mixed-methodology approach combining quantitative surveys and real-time digital usage tracking, we analyzed data from 250 employees across 23 organizations spanning multiple sectors (technology 26.5%, finance 16.7%, healthcare 13.6%). The research employs structural equation modeling and demonstrates robust interrelationships between variables (correlations ranging r=0.689 to 0.817), with digital literacy and employee commitment exhibiting the strongest correlation (r=0.817). Statistical analysis reveals that human capital significantly mediates the relationship between employee factors and organizational performance, explaining 72.3% of performance variance (R²=0.723). All constructs demonstrated strong reliability (Cronbach’s α: 0.739-0.787) and convergent validity (AVE>0.5). Multiple regression analysis identified attitude (β=0.218) and human capital (β=0.184) as primary performance predictors, while frugal innovation showed significant influence (β=0.172, p<0.001). The study found that 69.1% of participants utilize digital tools multiple times daily, with 44.4% at intermediate digital literacy levels. Path analysis confirmed significant positive relationships (p<0.001) across all variables, with attitude demonstrating the highest direct effect on organizational performance (0.525). The research extends human capital theory by empirically validating digital competencies’ role in organizational success and identifies a critical digital literacy divide impacting performance outcomes. In work environments (48.1% hybrid, 42% on-site, 9.9% remote), findings demonstrate the universal importance of digital competencies across different operational models. These results have substantial implications for management practices, organizational strategy, and human resource development in the digital era, particularly in fostering comprehensive digital skill development programs and addressing organizational digital divides.

The study’s central theme is sustainability practice. It aims to measure the impact of sustainability practices on market performance. The study is quantitative, and data was obtained through a structured questionnaire using a five-point Likert scale. Different firms, such as manufacturing, non-manufacturing, and service support, run the survey by sharing the data (n=200). Data were analysed through Smart PLS version 4.1.0.0, employing a structural equation model (SEM) technique to measure the impact of exogenous variables. All three variables (Employee engagement in sustainability, corporate social responsibility, and environmental concern) positively and significantly impact sustainability practice. Thus, the study’s central finding is that sustainability practice positively influences the market performance of the firms, and the association is also significant. Companies that adopt sustainable practices can differentiate themselves in the market, potentially improving their competitiveness. Companies can exploit the notion that sustainability is a highly efficient technique for stimulating growth. Integrating sustainable principles can lead to long-lasting economic advantages. The novelty of this work is that it considers sustainability practices to determine the impact on market performance. Future work can be conducted on the specification of market performance, such as sales growth, return on investment (ROI), return on assets (ROA), and earnings per share (EPS).
Urban Expansion and its Influence on Land Surface Temperature: A Case Study of Patna City, India

Published: December 2024

Rapid urbanization in developing countries has significant implications for local climate and environmental conditions. This study examines land use/land cover (LULC) changes and their impact on land surface temperature (LST) in Patna, India from 1988 to 2022 using Landsat imagery and geospatial techniques. Rapid urbanization in developing cities can significantly alter local climate, but the dynamics in Patna were not well understood. Using supervised classification and thermal band analysis, the research quantified LULC transformations and LST changes over 34 years. Results show dramatic urban expansion, with built-up area increasing from 38 % to 80 % of the total area, while vegetation cover decreased from 44 % to just 7 %. These changes corresponded with an overall increase in LST, with maximum temperatures rising by 1.06°C and minimum temperatures by 6°C. Strong correlations were found between LST and spectral indices like NDVI (negative) and NDBI (positive). The study reveals accelerated urban growth and temperature increases, especially after 2005, highlighting the need for sustainable urban planning strategies to mitigate heat island effects and improve thermal comfort in Patna. This research provides valuable baseline data for understanding urbanization impacts on local climate in rapidly growing Indian cities.
