Abstract

The primary aim of the present study is to evaluate the effects of hybridization ratio, fiber orientation, and mass fraction on the fiber/matrix bond properties of hybrid Gongronema latifolium stem/S-glass fiber reinforced epoxy composites. Gongronema latifolium plant stem fibers were collected from Anambra State, Nigeria, with leaves removed manually. Sodium hydroxide (2%) and epoxy resin (Grade-3554A) were used, while S-Glass was sourced locally. The fibers were extracted using a water retting method, treated with NaOH at 40-60°C for 4 hours, and dried at 70°C. For composite fabrication, fibers were aligned unidirectionally and mixed with resin and S-glass in a 250×100×5 mm mold. The hybridization ratio of S-Glass to natural fiber was fixed at 2.2 for Level 1 and 2.8 for Level 2. The mass fraction levels were at 21.24% for level one and 34.22% for level two. Fiber orientation of Level 1 was 45° while that of Level 2 was 90°. Mechanical characteristics were evaluated to ASTM D5651-21 for fiber-matrix bond strength and then analyzed using Statistical Package for Social Sciences (SPSS) and Microsoft Excel. Three models were developed, with the first model considering hybridization ratio, the second incorporating fiber orientation, and the third including mass fraction. The results show that the hybridization ratio is the most significant predictor of bond strength, with fiber orientation and mass fraction also contributing positively to the overall model. Models’ R-square values indicated how well the proposed models fitted the data: Model 1 = 0.747; Model 2 = 0.956; Model 3 = 0.980. Two unique solutions were examined further at fiber/matrix bond strength value of 0.32716MPa and value of 0.18070MPa, with a mean value of 0.25393 MPa and standard deviation value of 0.10356 MPa. The study reveals the impact of these factors on enhancing the bond strength of the composite material. The research has important and real-world applications for industries including construction, automotive, aerospace, and others where stiffer and more resistant composites are required. Future studies could be directed to investigate other variables and environmental factors that may influence performance of these hybrid composites to improve on their applications.

Abstract

In recognition of the need for sustainable design philosophies and practices that can be incorporated into the design of new products with an environmentally sustainable perspective throughout the life cycle, this research used a scoping review approach to x-ray the utility of the Sustainable Value Framework (SVF) in enhancing the application of reinforced composite products for ecological efficiency. An extensive search was performed using the electronic databases of articles such as PubMed, Google Scholar, Scopus, and Semantic Scholar. The study selected and extracted data from the literature according to the PRISMA-SCR (Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews) to map the current literature for gaps in knowledge. The research studies show that SVF promotes the product design by incorporating characteristics such as environmental, economic, and social factors to attain optimal reduction of resources and sustainable uses of the environmental resources as well as improving the quality of the products. The study discussed the principles of sustainable value creation and their work evaluates new solutions of composite material selection, design method and technology for sustainable products. It also discusses policy drivers as well as industry and consumer practices with regards to reuse of surfaces in sustainable design. This study is beneficial to various stakeholders like the policymakers, the professionals in industries and construction, and the scholars.

Abstract

This article examines when and how environmental scarcity and degradation lead to conflicts, and how countries resolve conflicts over the sharing of renewable resources between different states. Two research programs related to environmentally-based conflicts are reviewed, and about thirty activities for resolving environmental conflicts are listed. A single example of the Nile Basin Initiative is dealt with in particular detail. Three main conclusions can be drawn: First, scarcity of renewable resources and environmental degradation can lead to conflict when they interfere with each other under certain political and socio-economic conditions. Such conflicts can become serious in the internal settlement process, often in the context of political instability and poverty. International environmental conflicts, however, very rarely lead to military action. Yet the lack of international cooperation when sharing resources, based on the interests of various states, it really prevents the adequate development of these resources, thereby leading to overuse or underutilization of the resource, or to obvious “natural” disasters such as droughts and floods. These negative consequences, in turn, can collectively lead to poverty, migration and conflict. Second, there are indications that the assistance of a third party, usually an International Government Organization (IGO), is often more effective in reducing international tensions and enhancing environmental sustainability than conflicts governed solely by the conflicting parties themselves. Moreover, examples further demonstrate that conflict resolution efforts are likely to be more successful when they place a strong emphasis on common interests, focus on efficiency and require external resolution, and when they are jointly involved in sharing costs and revenues. Third, the above examples of conflict resolution show that International Governmental Organizations should strengthen their role as mediators from an independent third party. IGOs must support the participants without taking responsibility for the process itself or the results. A “cross-cutting” settlement, that is, measures to link the government with middle and lower-level leaders, is necessary to avoid shifting the problem from the international arena to the national level.

Abstract

Reliable energy storage remains a critical challenge in sustaining solar-powered systems within academic environments, particularly in Nigeria where erratic grid supply hinders teaching and research activities. Batteries constitute the most cost-intensive component of solar installations, and their economic performance determines long-term viability. The study integrated MATLAB/Simulink simulations, field observations, and expert input. The analysis followed three stages: system modeling, performance evaluation, and economic benchmarking. Monocrystalline PV modules (220–330 W, 18–20% efficiency) were configured with 7° tilt and passive cooling to optimize performance in Nigeria’s tropical climate. A 60A MPPT controller and 1 kW inverter enhanced efficiency, while protections improved system reliability. Life-cycle cost analysis (LCCA) over 15 years at 10% discount rate compared tubular lead-acid and LiFePO₄ batteries, revealing LiFePO₄’s long-term cost advantage. Sensitivity analysis and benchmarking confirmed its superior cycle life, reduced maintenance, and lower levelized storage costs. The life-cycle cost analysis showed that tubular lead-acid batteries were cheaper upfront (₦92,000/kWh vs. ₦230,000/kWh) but incurred higher O\&M (₦46,000/kWh every 5 years) and required replacements at years 5 and 10, raising their 15-year cost to ₦400,200/kWh. LiFePO₄, though costlier (₦481,100/kWh total), offered longer lifespan, lower O\&M (₦18,400/kWh), and higher salvage value (₦34,500). Net Present Cost was lower for tubular (₦248,500/kWh vs. ₦289,200/kWh), yet LiFePO₄ delivered a better Levelized Cost of Storage (₦98/kWh vs. ₦127/kWh) and achieved payback in 8.2 years. Thus, tubular favored affordability, while LiFePO₄ provided superior long-term value and reliability for Nigerian universities. The study recommends a shift toward durable storage technologies to enhance reliability, reduce operating costs, and strengthen energy security in Nigerian universities.

Abstract

Artificial intelligence (AI) has been identified to be very significant in the twenty-first century in almost every discipline, including engineering, science, education, medical, business, accounting, finance, marketing, economics, manufacturing, the stock market, and law. This study examined the impact of artificial intelligence on organizational performance in a microfinance bank. Relevant data were drawn from selected one hundred (100) staff of XYZ Microfinance bank based in Nigeria, using a well-structured questionnaire. The data collected were descriptively analyzed. The results showed that artificial intelligence has positive impact on the organizational performance. The results also revealed that high cost of implementation, anxiety among workers, role displacement, ethical issues, significant investment in technology and training, among others are the challenges affecting the adoption of artificial intelligence in the business organization in Nigeria. The study recommends that Businesses must take proactive measures to address the obstacles to AI adoption if they want to optimize the technology's beneficial effects on organizational performance.
