Authors: Odoma Saidi , Twinomugisha Felix , Neeza Timothy , Funso-Babarimisa Funso
Published: January 2025

Helminth infections affects nearly 1.5 billion people worldwide, particularly in tropical and subtropical regions, where poverty, inadequate housing, and poor sanitation, exacerbate their impact. These infections pose significant health and economic burdens, and the limited effectiveness of current anthelmintic drugs underscores the need for alternative treatments. Dimocarpus longan, traditionally used in various forms of medicine, is rich in bioactive compounds such as flavonoids, tannins, and saponins, which are known to exhibit antiparasitic properties. This study evaluated the anthelmintic potential of ethanol leaf extract of D. longan against Taenia solium, aiming to explore its use as a natural remedy for managing helminth infections. The extract, tested at concentrations of 25, 50, 100, and 200 mg/mL. alongside piperazine citrate (10 mg/mL) on adult T. solium worms obtained from freshly slaughtered pigs. The anthelmintic activity was measured by recording the time to paralysis and death of the worms. The extract showed significant concentration-dependent effects, with higher concentrations (100 & 200 mg/mL) demonstrating efficacy comparable to piperazine citrate, exhibiting strong paralytic but weaker lethal effects on T. solium. The findings suggest that D. longan ethanol leaf extract has potent anthelmintic properties, making it a promising natural alternative for managing helminth infection.

Published: January 2025

An increase in foodborne illnesses associated with fruits and vegetables has been observed in recent years, with several outbreaks linked to contaminated agricultural water. The effectiveness of peroxyacetic acid (PAA) and chlorine (Cl) at reducing Escherichia coli in rain barrel and creek water was evaluated in this study. Rain barrel and creek water (12 and 32°C overnight) were inoculated with ~5 log CFU/ml of an E. coli cocktail, reequilibrated to 12 and 32°C (30 min), and treated with 25 ± 2 ppm of Cl, 75 ± 5 ppm of PPA, or a water control (W). Samples were collected 0, 5, 10, 60, 1,440, and 2,880 min after treatment, neutralized in Dey–Engley broth, and enumerated using the Food and Drug Administration-approved IDEXX Colilert method, as well as E. coli/coliform (EC) Petrifilm, and enriched for the presence or absence of E. coli. E. coli was not detected in 12 and 32°C creek and rain barrel water 0 min after treatment with PAA and 60 min after treatment with Cl using Colilert. E. coli was not detected in samples treated with PAA or Cl at any time point using EC Petrifilm. These data allow growers and extension educators to explore the use of these treatments in surface water sources for postharvest uses in produce.

Published: January 2025

Developing the country's mineral resource base plays a key role in economic growth, especially through the exploitation of small deposits often located in complex geological conditions. For the successful implementation of mineral extraction projects in such conditions, it is necessary to consider not only geological features but also technical aspects, such as engineering-geological conditions. Investigating these features helps determine the optimal strategies for deposit development and ensures the safety and efficiency of mining operations. Engineering-geological studies, by analyzing the physical and mechanical properties, allow for a detailed understanding of rock masses and clarification of geological conditions to justify the most effective mining methods and the construction of mining facilities. One example of the interest mining companies have in developing promising areas located in complex geological settings is the Shuak Ore District discussed in this paper, which is associated with gold-copper-molybdenum mineralization and lies in a zone of tectonomagmatic activity. A comprehensive set of engineering-geological studies was conducted to assess the feasibility of constructing open-pit mines in the ore field areas. These studies included the examination of the physical and mechanical properties of drill core samples, the determination of the geological strength index, and the structural disturbance index of the rock mass. Based on these indicators, engineering-geological elements were identified, and rock strength passports for the rock mass were created, which are used to calculate the parameters of the open pits. General patterns of changes in rock fracturing of different compositions, degrees of oxidation, and weathering due to tectonic disturbances and intrusive contacts were established. These factors must be considered when organizing engineering-geological surveys, selecting mining directions, and planning operations in both host and ore-bearing rocks in each section of the ore district.

Published: January 2025

Knowing the distribution of the mechanical rock properties and in-situ stresses for the field of interest is essential for many applications concerning reservoir geomechanics, including wellbore instability analysis, hydraulic fracturing, sand production, reservoir compaction, subsidence and water/gas injection throughout the filed life cycle. Determining the rock's mechanical properties is challenging because they cannot be directly measured at the borehole. The recovered carbonate core samples are limited and only provide discrete data for specific depths. This study focuses on creating a detailed 1D geomechanical model of the Mishrif reservoir in the Nasriyah oil field to identify the fault regime type for each unit in the formation. This is particularly important in CO2-EOR as it helps to understand reservoir connectivity and optimize CO2 injection. A geomechanical model is also necessary to evaluate the behavior of the reservoir and cap rock. This model can help predict the stress distribution, deformation, and potential failure zones. The Mishrif Formation has five units (from CI to MB-2). Based on the current results, the cap rock units (CI, CII) possess weak mechanical properties. The 1D mechanical earth model highlights different faulting regimes within the Mishrif Formation across various wells;as wells as, different trends of elasticand mechanical properties across the formation units. Some wells exhibit reverse (thrust) type faulting in the reservoir units and normal faulting in the barrier units. Conversely, other wells display strike-slip faulting in the reservoir units and reverse/thrust faulting in the barrier units. Also, the reservoir units exhibited it’s stiffness, brittle strength, it’s endurance to shear force and proved it’s geomechanical stability due to the high values of static young modulus, unconfined compressive strength, bulk modulus and relatively high mechanical properties it's important to note that the in-situ stress has significantly decreased in the barrier units.

Published: January 2025

Defamation through social media has become a significant problem in the digital era. This study aims to analyze the process of resolving compensation claims due to defamation and the form of legal protection based on the Civil Code. The research uses a normative juridical method with a qualitative approach, referring to laws and regulations, court decisions, and legal doctrine. The results show that dispute resolution can be done through litigation and non-litigation channels. Litigation includes formal stages such as filing a lawsuit, mediation, proof, and a judge's decision based on Articles 1365 and 1372 of the Civil Code. Meanwhile, non-litigation channels such as negotiation and mediation emphasize peaceful settlement. Legal protection for victims includes material and immaterial damages, the amount of which is determined based on the perpetrator's guilt, causal relationship, and strong evidence. Although restitution is generally in the form of money, other forms of restitution are also possible. This study emphasizes the importance of a fair and proportional legal approach to safeguard victims' rights and prevent abuse of freedom of expression on social media.

Authors:   Department of Environmental Sciences, School of Climate Change and Sustainability, Institution of Eminence, University of Delhi, Delhi, India, Tabasum Sahima
Published: January 2025

The rapid advancement of industrial and agricultural activities has led to an escalation of pollution, with organic pollutants, particularly pesticides,
being directly discharged into water bodies. This contamination poses serious environmental and health challenges. Among these pollutants,
carbofuran, a widely used pesticide, significantly threatens aquatic ecosystems and human life. To address this issue, innovative approaches are
essential to mitigate the adverse effects of carbofuran. Nanocomposites have become promising materials for photocatalytic degradation of organic and
inorganic pollutants due to their exceptional physicochemical properties, cost-effectiveness, and high stability. Graphitic carbon nitride, a polymeric
material composed of carbon, nitrogen, and trace impurities, is gaining considerable attention for photocatalysis due to its unique semiconducting
characteristics and catalytic activity.
Recent studies reveal that doping g-C₃N₄ has high photocatalytic performance under visible light. g-C₃N₄ exhibits superior catalytic efficiency,
facilitating the mineralization of Atrazine in aqueous environments. This improved activity is attributed to the synergistic effects of the dopants, which
optimize the electronic structure of g-C₃N₄. The advancement of g-C₃N₄-based nanocomposites offers a promising pathway for the development of
effective and sustainable solutions to tackle water pollution and safeguard environmental health.
The nanocomposite is synthesized using hydrothermal and microwave techniques. The powder X- ray diffraction technique is employed to identify
the crystal structure of a ternary nanocomposite material, specifically focusing on the crystallite size, phase, and defects. The surface morphologies
and functional groups are assessed using SEM and Fourier-transform infrared spectroscopy (FTIR). The FTIR analysis reveals the presence of C–N
and C=N stretching modes in the heterocycle, characterized by bands ranging from 1200 to 1650 cm−1. The experiment aimed to study the effects
of several experimental factors, including pH, time, and Catalyst Dose, on the breakdown of Atrazine.

EXPLORING THE IMPACT OF MACROECONOMIC FACTORS ON VAT REVENUE IN NEPAL: AN EMPIRICAL ANALYSIS
Authors: Kandel Madan
Published: January 2025

This study explores the influence of key macroeconomic factors
on Value Added Tax (VAT) revenue collection in Nepal, with the goal of enhancing
tax efficiency and guiding policy formulation. Methods: The research employs an
Autoregressive Distributed Lag (ARDL) model on time series data to assess both shortand long-term impacts of economic variables, including Gross Domestic Product
(GDP), government expenditure, remittance inflows, trade deficit, and money
supply, on VAT revenue. Findings: Results indicate that GDP, remittances, trade
deficit, and money supply have a significant positive relationship with VAT revenue,
underscoring their roles in supporting VAT collection. Specifically, remittance
inflows bolster domestic consumption, thus expanding the VAT base, while the
positive relationship with the trade deficit implies that increased imports are a crucial
contributor to VAT revenue. However, government expenditure demonstrates a
weaker impact, suggesting inefficiencies in transforming public spending into tax
revenue. Conclusion: This study emphasizes the importance of economic growth and
remittance inflows in enhancing VAT revenue collection in Nepal and suggests that
government expenditure may require more effective structuring to translate into
greater tax revenue. Novelty: This study provides empirical insights specific to Nepal,
identifying how distinct macroeconomic variables impact VAT revenue and offering
evidence-based recommendations for optimizing tax policy.

This study explores the dynamic relationship between Environmental, Social, and Governance (ESG) disclosure and corporate value among listed Oil and Gas and Industrial Goods firms in Nigeria, covering the period from 2011 to 2022. Employing a nonlinear fixed-effect panel threshold regression model, the research evaluates the effects of high and low ESG disclosure regimes on corporate performance metrics, represented by Tobin’s Q and EBITDA. The findings reveal that high ESG disclosure regimes significantly enhance corporate value across both sectors, while low ESG regimes yield mixed results, particularly in the Oil and Gas sector. These results underscore the pivotal role of ESG practices in fostering sustainable corporate performance and align with signaling theory. This study contributes to the discourse on ESG strategies, offering actionable insights for policymakers, corporate leaders, and stakeholders aiming to optimize sustainability practices and financial outcomes.

Convex functions have a long and illustrious history. The history of convexity theory can  be traced all the way back to the end of the nineteenth century. The word ”convex  functions” has been widely used and explored in the well-known and popular book namely  ”Inequalities,” published by G. Polya, G.H. Hardy, and J.E. Littlewood [1]. This book is  quickly became a standard reference for mathematicians and dedicated solely to the topic of  inequality and serves as an excellent introduction to this fascinating field. Convex theory  provides us with appropriate guidelines and techniques to focus on a broad range of  problems in applied sciences. It has been widely acknowledged in recent years that  mathematical inequalities have contributed to the development of various aspects of  mathematics as well as other scientific disciplines. This theory have remarkable uses in  economics [2], optimization [3], mathematical optimization for modeling [4, 5], finance  [6], computer science [7], control systems [8] and estimation and signal processing [9].  This theory provides a solid framework for the start and growth of numerical tools for  the study and solution of challenging mathematical issues. The investigation of inequality has been regarded and viewed as one of the key fields of  ap-plied sciences. It is a fast-growing science with a rising number of applications in many  scientific domains. Integral inequalities have fruitful importance in integral operator  theory, stochastic processes, numerical integration, optimization theory, probability,  statistics and information technology.

Целью настоящей работы является исследование сорбционных свойств сорбентов, полученных на основе активированного угля (NoritRO, АКВАСОРБ) и шунгита. Эксперименты по определению оптимального сорбента проводились с цианистым раствором состава, мг/л: Au – 11,66; Ag – 2,16; Fe – 0,68; Cu – 8,45, Zn – 8,12. Установлено, что при сорбции золота с использованием сорбентов NoritRO, АКВАСОРБ и сорбента на основе шунгита, наибольшим значением емкости обладает ионит марки NoritRO. Оптимальным значением рН среды для извлечения золота с NoritRO и АКВАСОРБ явился 10, для сорбента на основе шунгита рН = 6. При проведении сорбции золота из многокомпонентного раствора с NoritRO наблюдается соизвлечение примесей металлов. При сорбции золота из реального цианистого продуктивного раствора с сорбентом NoritRO в 6 стадий степень извлечения золота достигает 96-99 %

Бұл жұмыстың мақсаты белсендірілген көмір (NoritRO, АКВАСОРБ) және шунгит негізінде алынған сорбенттердің сорбциялық қасиеттерін зерттеу болды. Оңтайлы сорбентті анықтау бойынша эксперименттер құрамның цианид ерітіндісімен жүргізілді, мг/л: Au – 11,66; Ag – 2,16; Fe – 0,68; Cu – 8,45, Zn – 8,12. Noritro сорбенттерін, АКВАСОРБТЫ және шунгит негізіндегі сорбентті қолдана отырып, алтынды сорбциялау кезінде Noritro маркалы ионит сыйымдылықтың ең үлкен мәніне ие екендігі анықталды. Noritro және АКВАСОРБ бар алтынды алу үшін ортаның оңтайлы рН мәні 10, шунгит негізіндегі сорбент үшін pН = 6 болды. NoritRO сорбентімен нақты цианидті өнімді ерітіндіден алтынды 6 сатыда сорбциялау кезінде алтынды алу дәрежесі 96-99% жетеді

The purpose of this work was to study the sorption properties of sorbents obtained on the basis of activated carbon (NoritRO, AQUASORB) and shungite. Experiments to determine the optimal sorbent were carried out with a cyanide solution of the composition, mg/l: Au – 11.66; Ag – 2.16; Fe – 0.68; Cu – 8.45, Zn – 8.12. It was found that when gold is sorbed using NoritRO sorbents, AQUASORB and a sorbent based on shungite, the ionite of the NoritRO brand has the highest capacity value. The optimal pH value of the medium for extracting gold from NoritRO and AQUASORB was 10, for a sorbent based on shungite, pH = 6.When gold is sorbed from a real cyanide productive solution with NoritRO sorbent in 6 stages, the degree of gold extraction reaches 96-99%
Improving expected shortage estimations in the base-stock policy by accounting for undershoots
Authors: Babiloni Eugenia , Guijarro Ester
Published: January 2025

Shortage events are inevitable random phenomena in inventory systems when dealing with real demand. For inventory managers, knowing the size of these shortages becomes crucial to deciding the optimal policy for the inventory system. Therefore, the Expected Shortage per Replenishment Cycle, ESPCR, is an essential indicator in inventory management for several reasons. On the one hand, it gives information about the number of units not served in each cycle, and on the other hand, it is fundamental in determining service levels or shortage costs. Therefore, ESPCR estimation for the continuous review base-stock policy (s, S) is traditionally based on the assumption that inventory levels reach exactly the reorder point, i.e., inventory levels are never below the reorder point, and undershoots are not considered. This paper shows that the traditional estimation based on neglecting undershoots is biased and proposes a new and unbiased approximation, ESPCRW. This approach is based on estimating the probability vector of the stock levels at the reorder point considering the presence of undershoots. Results of this paper show that our approach outperforms the biased nature of the traditional approximation, which may have significant practical implications for the inventory systems.
