Authors: Alfraidi Walied , Alaql Fahad , AlMuhanna Khalid , Farh Hassan M. Hussein , Al-Shamma’a Abdullrahman A.
Published: January 2025

Energy hub stations represent a transformative approach to modern energy systems, functioning as flexible nodes within distribution networks. By seamlessly integrating electric vehicles (EVs) and battery energy storage systems (BESSs), these hubs address critical challenges such as grid stress, renewable energy utilization, and peak load management. This study introduces a novel mathematical optimization model designed to maximize the operational flexibility of EV charging stations by transforming them into fully functional energy hubs. The model incorporates key parameters such as energy demands, load profiles, and grid conditions to optimize the sizing and operation of distributed energy resources, including photovoltaic (PV) systems and BESSs. The proposed approach minimizes grid dependency, enabling energy hubs to efficiently operate varying levels of operational flexibility, from full reliance on grid power to complete independence. The results reveal that, by effectively shifting energy usage away from peak periods and leveraging PV generation, energy hubs emerge as a critical component of sustainable energy systems and can independently support approximately 45% of their load, with minimal PV and BESS capacities. It also reveals a direct correlation between higher flexibility levels and increased infrastructure requirements for PV systems and BESSs. The proposed model underscores the critical role of energy hubs in facilitating the global shift toward decarbonization, aligning with contemporary goals for resilient and environmentally sustainable energy ecosystems. This work provides a scalable framework for future energy systems, with significant implications for policymakers, researchers, and practitioners in the fields of renewable energy and sustainable mobility.

the article contains current information on the main groups of drugs and algorithms for
their use in the treatment of chronic obstructive pulmonary disease (COPD). The authors of the
article show that the use of bronchodilators is a key link in the treatment of exacerbations. The
effectiveness of β2‑agonists and ipratropium bromide in exacerbations of COPD is approximately
the same, the advantage of β2‑agonists is a faster onset of action, and anticholinergic drugs
are high safety and good tolerability. For the optimal choice of an approach to the treatment of
COPD exacerbations, it is recommended to use biomarkers such as C-reactive protein, the use
of antibacterial therapy is rational with an increase in the level of C-reactive protein ≥ 10–20 mg/l (in many cases, the level of CRP less than 20 mg / l indicates a viral etiology), it can be useful
to assess such a specific marker as procalcitonin (a level of more than 0.5 is characteristic of a
bacterial infection).

It is important to use nutritious compound feeds with high content
of protein in order to obtain qualitative marketable fish products under an intensive
cultivation. During the production of high-protein aquaculture feeds,
protein-rich animal and plant ingredients should be added to the composition.
To such components refer: fish flour, meat-and-bone meal, wheat, corn,
various types of soybeans, etc. Animal ingredients can be partially replaced
by vegetable ingredients, but should not be 100%. Popular plant-based feed
additives are soybean and corn. They are rich sources of plant protein which
make them an ideal supplement to form a complete fish diet, especially in
conditions of the intensive cultivation. These ingredients are often cheaper
in comparison to animal proteins, which is the reason why the use of these
ingredients makes feed more affordable for fish producers. For producers,
semi-finished products of two or more ingredients are produced now as pellets
or dry mixes. It is made to simplify the production process. In the majority
of cases, these additives include a combination of animal protein and plant
protein. This paper considers plant components such as soybean and corn in
combination with fish flour for the manufacture of compound feeds. It also
presents amino acid compositions of these components. Studies on the determination
of the amount of proteins, fats and carbohydrates in experimental
feeds containing soybean and corn are conducted and described. In the
course of the experiment it is revealed that the feed with soybean content has
a higher percentage of crude protein content, but the feed with corn has a
higher content of carbohydrates in its composition.

This article concentrated on appraising the water quality of the Euphrates River in the city of Ramadi, Anbar Province western Iraq from the Ramadi Dam to the AL-Khalidiyah Bridge. Seven heavy metals: (Mn, Cu, Fe, Zn, Cr, Cd, and Pb) and ten positions were selected to assess the presence and concentration of these heavy metals in this part of the river. These heavy metals can be a risk and cause cancers due to they do not decompose and can accumulate in body organisms. The samples were analyzed using an atomic absorption spectrophotometer. Three indicators were utilized to appraise water quality: the Heavy Metal Evaluation Index, Contamination Degree, and Heavy Metal Pollution Index. The average concentrations of Mn, Cu, Fe, Zn, Cr, Cd, and Pb in the river water samples were found to be 15.87, 53.16, 152.1, 55.5, 10.41, 0.37, and 0.36 μg/L, respectively. The findings discovered that the concentrations of heavy metals in the samples are below the acceptable limits based on the World Health Organization (WHO). The average values of the indicators (HMPI, HMEI, and CD) were 49.106, 1.716, and -5.282 respectively, which are all below the acceptable limits established set by the World Health Organization. Based on these findings, the water quality of the Euphrates River in the study region is categorized as low pollution. Statistical analysis of heavy metals represented by Pearson correlation displays that the sources of the low pollution levels in the study region consequence of various human activities. Although heavy metal pollution in the Euphrates River in the study region is low, the river water cannot be pumped directly into residential units. This is due to the river water contains other pollutants, such as turbidity and suspended solids, and may also contain pathogens, including bacteria and viruses. Therefore, it must be treated at the water treatment plant before it can be used for drinking.

Published: January 2025

This concept paper examines the motivation to lead among secondary school teachers in Malaysia. Based on previous literature and studies, motivation to lead is an important factor in the development of effective teacher leadership. This paper explores the role of various factors such as personality, leadership values, self-efficacy, and previous leadership experience in shaping the motivation to lead. In addition, this paper also discusses the dimensions of motivation to lead which consists of affective identity, social normative and non-calculative as well as the importance of professional development programs that support teachers in improving their leadership skills. A literature review found that the concept of motivation to lead has long been practiced abroad but is still new in Malaysia and shows that teachers who are motivated to lead can improve the quality of teaching and student achievement, as well as play an important role in school renewal and excellence. This study gives implications for school administrators to plan and implement a comprehensive leadership development program to empower teachers as educational leaders.

This study explores the intricate relationship between Working Memory (WM) and mathematical proficiency, particularly focusing on its implications for cognitive development and academic achievement. WM, responsible for the temporary storage and manipulation of information, is crucial in shaping mathematical skills and cognitive functions. However, there remains a gap in understanding how WM deficits impact students, particularly those with Learning Disabilities (LDs). The research examines three key themes: the role of WM in mathematical and cognitive skills, the influence of numeracy and number sense on mathematical achievement, and the impact of cognitive function on LDs and academic performance. To achieve this, we extensively searched scholarly articles from reputable databases such as Scopus, Web of Science, and Eric, focusing on studies published between 2022 and 2024. The flow of the study is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. The database discovered (n = 20) that the final primary data was analyzed. The finding was divided into three themes: (1) WM and its roles in mathematical and cognitive skills, (2) numeracy, number sense, and mathematical achievement, and (3) cognitive functions, LDs, and academic achievement. Findings also reveal that WM plays a pivotal role in mathematical proficiency, with its components significantly influencing various cognitive and academic outcomes. Moreover, number sense is identified as a critical predictor of mathematical success, underscoring the need for early interventions. Lastly, the study highlights the challenges faced by students with LDs, where deficits in WM and related cognitive functions contribute to academic struggles. The research concludes that addressing WM deficits through targeted interventions could enhance mathematical performance and overall academic achievement, particularly for students with learning difficulties. These insights emphasize the necessity for educators and policymakers to integrate cognitive skill development into educational strategies, ensuring that students receive comprehensive support tailored to their cognitive needs.

This study examines the impact of socio-economic disparities on university students' rental housing preferences in Malaysia, a country where the rising cost of living and limited on-campus housing options pose significant challenges, especially for students from lower-income backgrounds (B40). The study aims to explore how socio-economic status influences students' housing decisions and the subsequent effects on their academic performance and well-being. Using a cross-sectional research design, data was collected from 103 students at a public university in Malaysia’s northern region through an online survey. The data was analyzed using one-way ANOVA, Kruskal-Wallis, and chi-square tests to identify differences in housing preferences across socio-economic groups. The findings reveal that students from lower-income families prioritize affordability, often compromising on housing quality and proximity to campus, while those from higher-income backgrounds (M40 and T20) can afford better-quality housing closer to the university. These disparities in housing choices underscore the need for targeted interventions by university administrators and policymakers to ensure that all students, regardless of their socio-economic status, have access to safe, affordable, and adequate housing. Addressing these issues is crucial for supporting the academic success and overall well-being of students from diverse socio-economic backgrounds.

Globally, airports are under growing pressure to enhance their resilience, foster growth, and ensure sustainability. In this context, non-aeronautical revenue has become vital in establishing prosperous airport businesses. This revenue encompasses income from activities outside core aviation operations, including retail activities, parking, and real estate. Through a thematic synthesis, this research integrates existing airport retailing literature by examining 19 selected studies published between 2021 and 2024. The study highlights key themes already explored and identifies areas that require further investigation. It was found that current research mainly focuses on food and beverage outlets and duty-free stores as primary retail revenue sources. Future studies should consider the impact of emerging technologies on airport retailing and examine passenger behaviour. This study aims to provide valuable insights into the evolving landscape of airport retailing amidst changing industry trends.
FINANCIAL SECURITY OF DELEGATED AUTHORITIES OF LOCAL GOVERNMENT BODIES: PROBLEMS AND DIRECTIONS OF IMPROVEMENT
Authors: BENOVSKA Liliya
Published: January 2025

Introduction. The financial provision of delegated powers of local authorities rests on two important problems: firstly, due to the lack of a clear and unambiguous legally enshrined division of powers of authorities and local self-government bodies, the source of their funding arises the problem of their duplication. Secondly, there is a discrepancy between the cost of delegated powers and the financial resources allocated for this purpose, which negatively affects the quality and availability of public services due to the inability of local authorities to exercise their powers.
The purpose of the article is to study the problems and risks of financial support of delegated powers of local government bodies and search for ways to improve them.

Results. It was revealed that the problems of legislative regulation of the distribution of powers of local authorities are based on the need to include mines in the constitution, which is a complex and long-term process. The analysis of the dynamics and structure of revenues and transfers from the state budget revealed the predominance of the share of targeted transfers in the structure of transfers and the simultaneous growth in the dynamics of the volumes of fixed revenues of local budgets.

Conclusions. It is advisable to improve the financial provision of delegated powers of local authorities in several directions: conceptual separation of powers of local self-government bodies and executive power; improvement of methodological approaches to calculating the value of delegated powers; use of inter-municipal cooperation.
