Authors: . Masirah , Prihanto A.A. , Firdaus Muhammad , Setijawati Dwi
Published: December 2024

In recent decades, awareness of waste management and sustainable use of natural resources has increased significantly. One sector that has significant waste potential is the fishing industry. Waste from fishing activities, such as bones, skin and fish scales, is generally considered organic waste and is often thrown away or not utilized optimally.

However, this waste has excellent potential as an alternative raw material for developing added value to a product. One example of a value-added product that can be produced from fishery waste is edible film. In the context of fisheries waste, using edible film as a waste processing solution can provide significant economic and environmental benefits. Edible film derived from fishing industry waste has potential as an environmentally friendly packaging material for food applications. The importance of developing this technology also includes food safety aspects, to ensure that edible film from fishery waste meets standards. Based on the variability of fishery waste, further studies are needed to detail optimal formulations and to address potential production challenges.
Effects of charge, dopant, and H saturation on the hydrogen evolution activity of Au25-based thiolate-protected nanoclusters
Authors: Laverdure Laura , Mammen Nisha , Häkkinen Hannu , Honkala Karoliina
Published: December 2024

This study examines the effects of charge, dopant type, and hydrogen saturation on the hydrogen evolution reaction (HER) activity of thiolate-protected Au25-based nanoclusters using density functional theory (DFT). By extending the analysis to include up to 10 hydrogen atoms, this work captures the behavior of these nanoclusters under realistic HER reaction conditions, providing a broader understanding of the catalytic properties. Our findings, supported by Pourbaix diagrams, reveal that high hydrogen coverages dominate under HER-relevant potentials. Pt- and Pd-doped clusters exhibit remarkable structural stability, retaining their icosahedral core even at high hydrogen coverage. The detachment of thiol (HSR) and HAu-S(R)H molecules creates more accessible active sites enhancing catalytic efficiency. These clusters also support low H (2H) coverage states at less negative potentials, further contributing to their superior catalytic activity. In contrast, Cu-, Ag-, Zn-, Cd-, and Hg-doped clusters undergo structural collapse of the icosahedral core as hydrogen coverage increases and stabilize only high coverage clusters (> 7 H), correlating with their lower reactivity. These results highlight the critical role of dopant-induced structural and electronic dynamics in governing HER pathways and provide new insights into designing efficient nanocluster catalysts for sustainable hydrogen production.
Genderfucking as a Critical Legal Methodology
Authors: Ashley Florence
Published: December 2024

In this essay, I theorize genderfucking as a critical legal methodology. Genderfucking is defined by its focus on the needs and experiences of those who ‘fuck’ with gender, resisting attempts at gender governance through laws, policies, and practices. Adopting a politics of messiness, genderfucking is critical of recognition and calls into question the state’s legitimacy in defining and policing gender categories. Genderfucking offers a rich and fertile approach for analyzing a social, political, and legal world indelibly marked by regimes of gender and, in so doing, steps on the path towards gender liberation.
A review on triggering factors and causes of infertility

Published: December 2024

Infertility affects approximately 10-15% of men and women worldwide, and it is influenced by a variety of factors. These include age, family history, nutrition, body weight, exercise habits, psychological stress, hormonal imbalances, and environmental factors. While infertility is often viewed as a physical condition, it also has profound emotional and psychological implications, impacting overall well-being.Individuals struggling with infertility, especially women, are more likely to experience mental health challenges, such as depression, anxiety, and stress. Infertile women often report a significantly lower quality of life compared to their fertile counterparts, with many experiencing feelings of inadequacy, grief, and isolation. About 23% of women facing infertility are diagnosed with anxiety disorders, highlighting the emotional toll the condition takes.The psychological impact is further intensified after failed fertility treatments like in vitro fertilization (IVF). Unsuccessful IVF attempts can lead to a sense of hopelessness, deepening depression, and anxiety, complicating the emotional landscape. Because of the mental health challenges associated with infertility, it is crucial to provide comprehensive care that includes emotional support. Addressing the psychological aspects of infertility alongside physical treatment can improve patients’ well-being, making it a vital part of holistic infertility management. Supporting emotional health is essential to help individuals cope with the emotional burden infertility brings.

Authors: Reddy Penaka Nomika , Anudeep P Venkata , Penabaka Venugopalaiah , Chandra Yadala Prapurna
Published: December 2024

This study focuses on creating and assessing hydrogel beads containing Flecainide. Hydrogels are polymer networks that absorb and retain significant amounts of water. Within this network, hydrophilic groups become hydrated in aqueous environments, forming a hydrogel structure. The primary goal was to evaluate the formulation of hydrogel beads with Flecainide. Preliminary studies, including solubility and UV analysis, confirmed the formulation's requirements. FTIR spectra indicated no interaction between Flecainide and the polymers, suggesting that the distribution of Flecainide within the beads was appropriate and within acceptable limits.Additionally, the study demonstrated that as the polymer concentration increases, the amount of medication released decreases. The Flecainide hydrogel beads exhibited controlled and extended drug release in vitro. The dissolution data for the optimal formulation (F12) were analyzed using three kinetic models: the Higuchi and Korsmeyer-Peppas equations, zero-order, and first-order kinetics. The r² value for the optimized formulation F12 is 0.974, indicating compliance with zero-order release kinetics. Furthermore, the Korsmeyer-Peppas analysis supports the mechanism of drug release. For formulation F12, the "n" value is 1.021, indicating a supercase transport mechanism.

Катализаторы на основе феррита меди и алюмината меди проявляют высокую активность в реакции окисления СО. В данной работе проведено детальное in situ исследование методами спектроскопии рентгеновского поглощения восстановления CuFe2O4 и CuAl2O4 в потоке СО в диапазоне температур от 30 до 600°C. Показано, что в потоке CO феррит меди и алюминат меди восстанавливаются с образованием металлической меди. Восстановление меди с Cu2+ до Cu1+ и Cu0 происходит в феррите меди при более низких температурах (250–300°C), чем в алюминате меди (выше 400°C). Восстановление феррита меди также приводит к образованию металлического железа. Процесс восстановления происходит в несколько стадий: CuFe2O4 → Fe3O4 → FeO → Fe.

Published: December 2024

Interior point methods have seen significant advancements in recent decades for solving linear, semi-definite and quadratic programming. Among these methods, the logarithmic barrier methods based on approximate functions have polynomial convergence and are known for their favorable numerical performance. In this work, a new minorant function for the barrier method is proposed for solving convex quadratic problems with inequality constraints. The proposed minorant function allows to compute the steplength easily and quickly, unlike the line search method, which is computationally intensive and time-consuming. Mathematical results concerning the convergence of the algorithm are established. The numerical comparisons with the inexact Wolfe line search technique show that the proposed method is promising and effective.

Authors: Boukary Ouedraogo , Malicki Zorom , Elisée Gouba
Published: December 2024

In this article, we present a mathematical model for the transmission of HIV with the compartment of individuals in remission and vertical transmission describing the dynamics of the spread of the HIV/AIDS epidemic in a community. In the mathematical analysis of the model, we compute the basic reproduction number R0 and study the existence and stability of the disease-free equilibrium point. We also formulate an appropriate optimal control problem and study the conditions necessary for disease control to determine the role of preventive measures and treatment in reducing the spread of HIV/AIDS. Indeed, we study the impact of these control variables taken separately and combined. So we find that treatment is more cost-effective in reducing the spread of HIV than preventive measures. Finally, the numerical results conform to the theoretical analysis.

Published: December 2024

Energy prices and the stock market are two of the crucial factors in the evolving landscape of global finance, particularly in major emerging economies. However, research on how energy price changes impact stock markets in BRIC countries remains limited, despite their diverse roles in global energy markets and economies. This study investigates the causal dynamics between energy prices and stock market performance in BRIC countries, aiming to uncover short-term fluctuations and long-run relationships in these major emerging economies. Utilizing daily data from 2013 to 2023, stationarity tests, cointegration analysis, and Granger causality tests are employed to examine these relationships. Key findings reveal weak evidence of a long-run equilibrium between energy prices and stock market indices, challenging previous assumptions about their cointegration. More significantly, the findings uncovered a strong unidirectional Granger causality from oil prices to all BRIC stock market indices, while gas prices show a more selective influence. Notably, no evidence of reverse causality from stock markets to energy prices was found, highlighting the exogenous nature of global energy prices in relation to BRIC stock markets. This study uniquely analyzes oil and gas price effects on BRIC stock markets, offering insights for investors and policymakers amid increasing commodity-financial market integration. Doi: 10.28991/ESJ-2024-08-06-015 Full Text: PDF

Published: December 2024

The purpose of this study is to explore the effects of transformational leadership (TL) on project success (PS), focusing on the indirect impacts of leader-member exchange (LMX) and the moderating influence of professional commitment (PC). This study aims to address the inconsistent findings in existing literature regarding the transformational leadership-project success relationship and to uncover the mechanisms that affect project outcomes. The unit of analysis is finished projects. The 509 project managers on projects completed within the past five years responded to the poll to collect data. The data were then assessed using Smart-PLS software. The results confirmed the study’s hypotheses, demonstrating that LMX mediates the relationship between transformational leadership and project success. Additionally, professional commitment was found to moderate both the relationship between transformational leadership and LMX and the connection between LMX and project success. Furthermore, transformational leadership was shown to have a direct positive effect on project success. These findings contribute to the theoretical foundations of leadership and project management by emphasizing the critical role of relationship quality within teams, with LMX serving as an intervention mechanism and professional commitment acting as a moderating role influencing project success. The insights from this study offer practical value for developing project management strategies tailored to specific organizational contexts, enhancing efficiency in project-based organizations. Future research should consider longitudinal studies to explore how the relationships between these antecedents and project outcomes evolve over time. Doi: 10.28991/ESJ-2024-08-06-022 Full Text: PDF

Financial Development Strategies of Countries: Identifying Priority Financial Instruments
Authors: Gospodarchuk Galina , Zeleneva Elena
Published: December 2024

The effectiveness of financial development strategies for countries depends on the methodology used for their formation and implementation. However, a review of the literature reveals that the methodology for implementing these strategies is not fully developed. Therefore, this study aimed to create a methodology for implementing financial development strategies by identifying priority financial instruments. The study utilized rule-based judgment, iterative methods, and the "GAP" method. As a result, the "5S+" concept was developed—an expanded version of the "5S" concept. The novelty of the "5S+" concept lies in its inclusion of financial instruments, as well as the rules and methods for determining priority financial instruments. This is the first time such a modification of the "5S" concept is proposed. The "5S+" concept was tested using data from the UK for 2007-2022. The test results allowed us to determine the UK's strategic financial development goals for 2023-2025 and identify priority financial instruments necessary to achieve these goals across the board. The expanded "5S" concept is highly representative, objective, and broadly applicable. It enhances the existing methodology for strategic financial development management and introduces new opportunities for improving the quality of strategic policy documents. Doi: 10.28991/ESJ-2024-08-06-06 Full Text: PDF

The rise of digital media has profoundly influenced childhood development, especially during critical phases of growth. The American Academy of Pediatrics and World Health Organization advocate limiting screen time for children aged 2–5 years to less than one hour daily, emphasizing high-quality content and parental supervision. The COVID-19 pandemic accelerated screen usage in India, amplifying risks such as speech delays, cognitive and motor skill deficits, and emotional challenges. This study examines developmental outcomes linked to screen time among 0 to 6 years children in Pune, India, analyzing socio-demographic and parental factors affecting screen use. Data from 80 participants were collected through parental interviews, assessing media device availability, screen time, and developmental performance using the Communication DEALL Developmental Checklists (CDDC). Results revealed that children from rural areas (65.7%) and those with educated parents (particularly graduates) exhibited higher screen use. Devices like smart phones (63.9%) and laptops/computers (79.2%) were strongly linked to excessive screen time. Developmental analysis identified receptive language and social skills as significant predictors of screen time. Multivariate findings indicated social skills as an independent predictor, while activities of daily living approached significance. The study highlights the urgent need for targeted strategies to manage screen time effectively, particularly for children with limited social skills or those in environments with high media exposure. These insights offer a basis for policy recommendations, emphasizing parental guidance and education to mitigate the long-term impacts of excessive screen use.

Energy efficiency represents a key factor in building design and operation. In the Republic of Kazakhstan (RK), where buildings occupy the first place (43%) in terms of energy consumption, the residential sector plays an important role, especially considering its cold climate with long winters. Heating and lighting systems are the main elements of energy consumption in residential buildings. The statistical analysis within the framework of the study allowed revealing the drivers of high specific thermal energy consumption, including low tariffs and lack of investment in building thermal upgrading. The article presents the analytical findings on the energy consumption in Kazakhstan’s housing sector, as well as describes the main reasons for high energy consumption for housing heating, inter alia low investment on behalf of property owners in the context of low energy prices. The materials collected by the author as a result of direct participation in the preparation and execution of several pilot projects demonstrate the potential contribution of technical measures to the overall energy consumption reduction in various climatic conditions across the country; made it possible to calculate the profitability of a set of energy-efficiency measures for a standard apartment building, as well as formulate recommendations for improving energy efficiency in the residential sector. Curtailing energy consumption in the sector will contribute to reducing greenhouse gas emissions, which is especially important for achieving the goals of national climate policy, including the Concept for the Transition of the RK to a “Green Economy”, Kazakhstan’s Nationally Determined Contribution (NDC) and Strategy of the RK for Achieving Carbon Neutrality by 2060. The study outputs are based on the data as of late 2021 and show the potential of new technologies and targeted energy strategies to mitigate climate change impacts.
Does the Choice of Cooking Fuel Impact Happiness and Life Satisfaction?
Authors: Sumiyati Tatik , Hartono Djoni
Published: December 2024

The subjective experiences and perceptions of people when switching to cleaner cooking fuels are typically ignored in favor of objective indicators like respiratory health or time spent gathering firewood. Given that a sizable section of the populace still cooks using traditional biomass fuels while the country moves toward cleaner fuels like LPG and electricity, this research gap is particularly important in Indonesia. This study examines the association between the use of cleaner cooking fuels and two dimensions of subjective well-being: happiness and life satisfaction, using data from the most recent wave of the Indonesia Family Life Survey (IFLS). Propensity Score Matching (PSM) and Ordinary Least Squares (OLS) are used in this analysis to mitigate selection bias and precisely evaluate treatment effects. The empirical results reveal that the use of clean cooking fuel positively impacts an individual's subjective well-being, enhancing both happiness and life satisfaction. Individuals in rural areas get a more pronounced effect. The findings will offer important perspectives for decision-makers and interested parties focused on enhancing access to clean cooking energy and elevating subjective well-being in Indonesia, particularly in rural regions.

The objective of the present study was to assess the patterns of selenium, zinc, and magnesium metabolism in patients with inflammatory ar-thropathies (rheumatoid arthritis, gout, psoriatic arthritis) and polyarthritis through assessment of elemental levels in blood serum and hair. Material and methods. During a study, patients with polyarthritis (n = 128) and inflammatory arthropathies including rheumatoid arthritis (n = 100), psoriatic arthritis (n = 32), gout (n = 135), as well as 110 healthy subjects representing the control group were examined. Assessment of selenium, zinc, and magnesium levels was performed using high-sensitive method of mass spectrometry with inductively-coupled plasma. Results. The obtained data demonstrate that the level of Se in serum of patients with rheumatoid arthritis, psoriatic arthritis, gout, and polyarthritis was %, 11%, 5%, and 9% lower compared to healthy controls. Serum Zn concentrations in patients with rheumatoid arthritis, psoriatic arthritis, and polyarthritis were also lower than in the control group by 7%, 17%, and 7%, respectively. Hair analysis revealed a significant 20% decrease in seleni-um levels in polyarthritis patients compared to controls. Magnesium content in hair of patients with psoriatic arthritis and gout was 41% and 46% lower when compared to healthy examinees, respectively. At the same time, hair Zn levels in examinees suffering from rheumatoid arthritis, psoriatic arthri-tis, gout, and polyarthritis was 7%, 13%, 15%, and 12% lower than in the control group. Conclusion. Therefore, the results of the study demonstrate a significant decline in systemic levels of selenium, zinc, and magnesium, all pos-sessing antioxidant and anti-inflammatory effects, in patients with polyarthritis and inflammatory arthropathies, thus indicative of their potential in-volvement in pathogenesis of the studied diseases.

Introduction. The most popular education in Russian higher education institutions is among applicants from Central Asian countries, including Ka-zakhstan, Tajikistan, Turkmenistan, Uzbekistan and Kyrgyzstan. Students from this region make up more than half of all foreign citizens studying in Russian universities. Changed environmental conditions lead to the development of stressful situations, decreased learning ability and, in the future, the possible development of a number of diseases closely related to the presence of various elementoses. In this regard, in addition to the socio-cultural adaptation of students, it is very important to pay attention to the study of the elemental status of students in the process of their further adaptation to the changed living conditions. The aim of the study – a comparative analysis of the elemental status of first-year students from different climatic and geographical regions of the world who arrived to study in the Russian Federation and students living in the territory of the Russian Federation. Material and methods. From September 1, 2022 to January 1, 2023, a study of the elemental composition of hair was conducted using inductively coupled plasma mass spectrometry in 180 first-year students of RUDN University who had previously lived in the Middle East (60 people) and in the Moscow region (120 people). The age of the subjects was 18–26 years, the average age was 22.7 ± 4 years. Gender differences in the comparison groups were not taken into account. Differences in samples were determined using the Mann–Whitney test for independent samples (significance level p < 0.05). Results. The presented results of a comparative analysis of the content of Zn, Mo, Mn, Cr elements in the hair of students who arrived from the coun-tries of the Middle East, Central Asia and regions of Central Russia during the adaptation period to training in 2023 are characterized by reliable differ-ences in the content of essential microelements in various biosubstrates. Conclusion. The established features of the elemental profiles of students showed that the hair of the subjects reflects the territorial climatic and ge-ographical features of the region of residence of the examined persons.
