Water disinfection is an essential phase in the water supply process conducted to ensure safe drinking water, serving as the last barrier against the transmission of bacterial and viral infections through water. The main factors affecting disinfection efficiency, and consequently the type of water treatment process, include the type and concentration of organisms to be removed, the type and concentration of the disinfectant, contact time, and the chemical nature and temperature of the treated water. Therefore, this paper presents the results of the removal of selected strains to examine the effective dose and contact time of sodium hypochlorite. The results show that the application of this disinfectant can effectively remove the selected strains. A significant reduction in bacterial count was achieved, ranging from 2 to 4 log units depending on the sensitivity of the strain, at a C∙t value of 120 min∙mg/l, i.e., a dose of 2 mg/l and a contact time of 60 minutes.

Authors: Stankov Stanko
Published: October 2024

Intelligent solutions for monitoring water supply and guaranteeing the necessary quantities of water for citizens and the economy are increasingly being applied in modern cities. One of the main goals of the intelligent control of water resources is the minimization of leakage losses, using modern electronic devices, which increases the efficiency of drinking water use. The paper discusses the control and supervision of hidden leaks based on appropriate sensors, methods and modern equipment for detecting those leaks. A smart water network is not only a stand-alone system that optimizes efficiency, but also a means of connecting many systems and sharing data across platforms. New technologies extend the life and increase the reliability of equipment by measuring, acquisition and analyzing data from a wide range of events within the network. Information technologies in water supply enable: real-time monitoring, automation and optimization of complex processes, database sharing and synchronization, avoidance of inefficient duplication and inconsistency, visualization of data coming from different systems, data comparability and reporting; process planning. In addition to reducing water losses, the application of new technologies contributes to greater network productivity.

Authors: Taseski Goce , Krstovski Nikola
Published: October 2024

The rapid growth of the price of electricity has led to the need for the management of water supply systems to have a new primary goal, which is the capture of new underground gravity sources of water that are at a relatively greater distance from the existing water supply system, in order to reduce the quantities of water that are provided by pumping. The purpose of this paper is to develop a mathematical model for a technical economic analysis (cost benefit analysis) of an existing water supply system for which an additional gravity source of water is foreseen, where by analyzing the construction costs of the gravity pipeline and the total operating costs of the system such as: maintenance, depreciation and electricity costs, the optimal amount of water that should be taken from the future gravity water source will be determined.

Importance of rural water supply for improving water supply security
Authors: Dimitrijević Zoran
Published: October 2024

Water supply for the population and the economy is of key importance for every state and every local self-government, since safe water is the most important factor for the good health of people and livestock. The increased threat of terrorism in the 21st century requires special attention to the sensitivity of water supply systems to possible terrorist threats that include physical destruction of facilities or equipment, attacks on supervisory control sysystems and other computer systems, possible intentional biological-chemical or radiological contamination of water. Protection in the state, local self-government and the water supply organization must be established at all levels, consisting of: ministries, city administrations, employees with the aim of protecting the entire water system that contains facilities (source, raw water transport, water purification plants and distribution network down to the sprinklers themselves) and associated equipment, with established clear procedures. Under these conditions, rural water supply systems are an important alternative source of water supply that can increase resilience of water supply in rural areas and provide emergency supply even to larger population. Therefore, investing in the improvement of rural water supply systems is extremely important from the aspect of overall water supply security.

Authors: Vuksanović Darko , Radonjić Dragan , Šćepanović Jelena
Published: October 2024

The quarries, due to their area of exploitation, generate stormwater that needs to be dealt with in a legally regulated manner, in order to protect the environment. When examining each surface mine, it is necessary to determine in detail whether there are surface and underground streams at the location and in the surrounding area. Usually, the location of the quarry, that is, the exploitation field is located in a limestone area, so surface water that occurs due to precipitation must be dealt with in an appropriate manner, due to the very technological process that takes place at the quarry. At quarries, due to their area of exploitation, rainwater is generated, which needs to be dealt with in a legally regulated manner, in order to protect the environment. When examining each surface mine, it is necessary to determine in detail whether there are surface and underground streams at the location and in the surrounding area. Usually, the location of the quarry, that is, the exploitation field is located in a limestone area, so surface water that occurs due to precipitation must be dealt with in an appropriate way, due to the very technological process that takes place at the quarry. In order to be able to make an adequate calculation of precipitation water, multi-year monitoring of precipitation in a given area is carried out, namely: • mean annual amount of precipitation, • annual fluctuation of precipitation, • the highest rainfall for the month in the monitoring year, • maximum daily precipitation, • maximum hourly precipitation. The aim of the work is to show how important it is to collect rainwater from quarries, in order to resolve their further treatment and discharge into the recipient, for the reason that these waters can be significantly contaminated, so their discharge without prior treatment could have a significant negative impact. impact on the quality of the environment.

Authors: Jovanović Aleksandar , Bugarčić Mladen , Mišić Milica , Anđić Dimitrije , Sokić Miroslav , Pavićević Vladimir
Published: October 2024

Pollution of water bodies is a significant issue in modern society, with increased concentrations of organic pollutants rendering standard water treatment techniques insufficient to meet legal water quality standards. To reduce ecological pressure and mitigate the toxicity of these pollutants, it is necessary to oxidize and transform them into non-hazardous forms. Advanced oxidation processes, particularly photocatalysis, have gained prominence for this purpose. Photocatalysis enables the complete conversion of organic matter into carbon dioxide and water. Optimizing process parameters can further enhance the efficiency of photocatalysis in industrial wastewater treatment plants.

Authors: Cadiz Arlon
Published: October 2024

Abstract. One of the important aspects, apart from the learning environment and teaching and learning resources, is the quality of our teachers. The teachers are the drivers of the curriculum in the classroom. This study aimed at developing and validating a test instrument for assessing the content knowledge of 27 elementary science teachers in Grade 3 Science. Findings revealed that all indicators relative to the characteristics of the assessment tool are highly evident with a weighted mean of 3.87 based on the results of the validation. The assessment tool can be used to effectively assess the science teachers’ content knowledge in Grade 3 science. Moreover, Cronbach’s alpha values of 0.73 for the test items based on the results of the evaluation of the content experts imply that the assessment tool is acceptable in terms of internal consistency. The mean of the content knowledge test scores of 44.07 out of a possible 58 and the item and scale analyses as well as validity checks indicate that the final version of the content knowledge test questionnaire is a good instrument to measure the content knowledge of Grade 3 science teachers. A consistent level of test difficulty and discrimination indices were evident, and the results provided varied points in terms of the interpretation of the test items. The number of retained items and modified or revised items supports the validity and reliability of the test instrument in general.

Social Risk Factors and the Acceptance of Islamic Microfinancing in Northwestern States in Nigeria
Authors: Umar Bello UMAR  , Saifullahi Shehu IBRAHIM  , Sagir GAMBO
Published: October 2024

Paradigm shift is made here from the adaption of traditional behavioral theories such Theory of Reasoned Action (TRA) and Theory of Planned Behavior (TPB) to the adaption of Conceptual Framework of Social Risk Factors for Value-based Payments (SRF-VBP) in modelling Islamic microfinance acceptance. The SRF-VBP has been used in Health Care Services Sector. This study rectifies a failure in the previous models to account for social risk factors in estimating the determinants of Islamic microfinance acceptance. The study modelled the influence of social risk factors – economic condition, cultural context, gender and social relationships to broaden the understanding of factors influencing Islamic microfinance acceptance beyond what is already known through the behavioral theories. Quantitative research design was employed. Data was collected from sample of 367 agribusiness microentrepreneurs. Through the deployment of the modified SRF-VBP framework, the data was analyzed using multiple regression analysis. The results revealed the relevance of social risks factors in explaining Islamic microfinance acceptance. Specially, within the socio-economic factors - income source was found to significantly influence Islamic microfinance acceptance but income level, financial condition and educational level were insignificant. For cultural context, both additional wives plan, and childbearing plan are positively significant. However, gender was found to be an insignificant determinant. Lastly, social relationship factors -marital status, existing number of wives and existing number of children were also found to be significant determinants of Islamic microfinance acceptance. The practical implication could be careful evaluation of social risk factors in providing the relevant finances to the agribusiness microentrepreneurs by Islamic financial institutions especially for profit-oriented ventures. This is to ensure that the finances are used for business empowerment purposes rather than solving self-enforced social problems andsocial ceremonies. It also highlights the need for Islamic social financing through Zakat and Qardul-Hassan financing to address genuine social risks issues in Muslims communities. The study expands the understanding on the determinants of Islamic microfinance acceptance through the deployment of SRF-VBP framework into Islamic finance literature. Earlierstudies focussed on behavioral factors through the application of traditional behavioral theories. To the researchers’ knowledge the use of SRF-VBP framework to explain the influence of social risks factors on Islamic microfinance acceptance has not been availed in the literature.
The Link between Corporate Board and Financial Performance: Evidence From Money Deposit Banks in Nigeria
Authors: Musa Musa Muhammad , Adamu Idris Adamu , Hussaini Bala
Published: October 2024

This study investigates the effect of board structure on financial performance of listed DMBs in Nigeria, using a sample of ten (10) DMBs. The study covers a period of 10years (2011-2020) and employed correlation research design. Random effect regression was adopted. The study found that gender diversity on board has a statistically significant positive effect on the financial performance of listed DMBs in Nigeria.  The regression result shows that increasing the size of the board does not affect financial performance. The regression analysis also revealed that increasing the number of meetings held per year does not have significant effect on the profitability. Thus, increasing the number of meetings held in a year is not necessarily going to improve financial performance. It is recommended that listed DMBs should focus on expanding the quota of female directors serving on the board, as this will help to increase the companies' profitability potential.

Published: October 2024

The Global Wind Energy Council (GWEC) reported that in 2021, global wind capacity increased by 93.6 GW (+12%), reaching a total of 837 GW, most of which was contributed by wind turbines. Improving wind turbine performance primarily hinges on advancements in blade technology and airfoil design. This study examines the effect of profile thickness on the aerodynamic performance of the S830 airfoil at a Reynolds number of 25,148, as part of the NREL airfoil's aerodynamic performance research. However, the impacts of additional variables—such as angle of attack, Reynolds number, speed range, and particularly ice accretion—have not been thoroughly investigated. This study utilized a 2D CFD model provided by the commercial software ANSYS Fluent and FENSAP-ICE. The lift-to-drag ratio of the S830 wind turbine airfoil was examined, considering the effects of angle of attack, wind speed, Reynolds number, airfoil thickness, and ice accretion. Additionally, design-related solutions will be suggested. The research indicates that the optimal angle of attack increases the lift-to-drag ratio by approximately 250% compared to a zero angle of attack.  An increase in wind speed causes this coefficient to rise nonlinearly within the studied velocity range. The Reynolds number directly influences the optimal angle of attack. According to CFD results, the lift-to-drag ratio can be increased by 50% if the airfoil's thickness is reduced by 20% compared to the original profile. For the ice accretion simulation model, a case test of the NACA 0012 airfoil was conducted to verify the model's parameters. Subsequently, a survey of this phenomenon on the S830 airfoil revealed that the lift coefficient decreased by 5.25% after 90 minutes of ice accretion.

The role of the Regional Planning, Research and Development Agency of Bengkulu Province is a Regional Apparatus Organization (OPD) that plays a role as a supporting element for the government in the field of regional development planning. The purpose of this study is to find out the Role of the Regional Planning, Research and Development Agency of Bengkulu Province in Development Planning in Bengkulu whether it has run optimally in the development planning process in Bengkulu. The method used in this study is a qualitative method with a descriptive approach. The theory used in this study is the role theory from Soerjono Soekanto with indicators of active role, participatory role and passive role. The results of the study show that the implementation of the role of BAPPEDA of Bengkulu Province in development planning in Bengkulu has not fully gone well. Based on the results of observations, the researcher still found several problems in the passive role of the Bengkulu Provincial BAPPEDA that were experienced, such as differences in Central Policies (between Ministries/Institutions) related to the preparation of planning and development documents at the regional level. Second, the synergy of development planning, both at the regional and national levels, has not been optimal. The third is the difference in interests between Regencies/Cities in Bengkulu Province.

The Impact of Digital Storytelling on the Promotion of National Identity among Preschool Children
Authors: Almohaimeed Rasha , Amzah Fadzilah
Published: October 2024

With the advent of digital storytelling, educators now have powerful resources to inspire national identity in the next generation and open new avenues for creative learning in preschool. This paper reports on a case study that explores the impact of digital storytelling (DST) on the promotion of national identity. This study used a qualitative approach to investigate the observed phenomenon. The context of this case study involves the utilization of DST within a modern, technologically equipped kindergarten that has adopted the new Saudi curriculum. Six preschoolers were included in this case study, and a range of qualitative data were collected through observations (notes, photographs, video recordings), nonparticipant and interaction observations, and children’s artifacts. Thematic analysis revealed that DST is a valuable tool for promoting national identity among preschool children. By incorporating DST into early childhood education, educators can effectively engage young learners in exploring their cultural heritage, thus promoting a sense of pride, belonging, and connection to their national identity.
