Abstract

The study evaluates the potential of rice husk (RH) and sawdust (SD) as energy sources by analyzing their physicochemical properties and combustion efficiencies. These common waste materials from Gwagwalada, Abuja, Nigeria, were processed into briquettes at varying ratios. Proximate analysis showed moisture content of 7.5–9.2% and ash content of 2.1–3.5%. Calorific values ranged from 18,509.84 kJ/kg (100% SD) to 22,658.77 kJ/kg (100% RH). The burning rate (BR) correlated with calorific value, with the 50:50 SD/RH mixture having the highest BR (0.003 g/min), indicating rapid combustion, while 100% SD had the lowest BR (0.0015 g/min), supporting slower combustion. All briquettes exhibited smokeless behavior, reducing greenhouse gas emissions and offering a clean energy alternative. This study highlights the potential of agricultural waste for energy security, environmental management, and rural economic development in Nigeria.

Abstract

Sustainability and green engineering are increasingly vital in mechanical engineering education as industries prioritize environmental responsibility, energy efficiency, and waste reduction. This study aims to review and synthesize current research trends, challenges, and implementation strategies concerning the integration of sustainability into mechanical engineering curricula. We used a systematic review approach using literature published between 2019 and 2024. Results indicate that although sustainability is recognized as important, its integration remains inconsistent due to curriculum gaps, limited hands-on experiences, weak industry collaboration, and insufficient faculty training. Proposed solutions include project-based learning, interdisciplinary courses, strengthened partnerships with industry, and the incorporation of green technologies such as carbon capture and circular economy practices. These strategies are essential because they bridge the gap between theory and real-world application. The findings highlight the need for standardized educational frameworks and enhanced collaboration. This review contributes to the development of curricula that prepare future engineers to address complex environmental challenges.

Abstract

The demand for high precision and efficiency in industrial cutting operations has driven the development of automated positioning mechanisms. Most traditional manual stopper systems in panel saws often suffer from inaccuracies, inefficiencies, and material waste. To address these issues, this study presents the design, implementation, and performance evaluation of a PLC-based automated stopper mechanism utilizing a ball screw system for precise linear motion. The system integrates a Programmable Logic Controller (PLC), stepper motor, ball screw mechanism, and Human-Machine Interface (HMI) to enable accurate positioning and real-time operator control. Performance tests validated the system’s reliability, precision, and suitability for industrial cutting applications. Speed evaluations confirmed that the stopper exceeded the 40 mm/s requirement, achieving 43.4 mm/s. Force resistance tests demonstrated structural stability under a 100 N load, with minimal deviations of 0.05 mm at 125 N and 0.10 mm at 150 N. Positioning accuracy tests further confirmed an average error of only 0.1 mm (0.005% deviation). The PLC executed motion commands with an average response time of 0.5 seconds, ensuring quick and reliable adjustments. These findings highlight the effectiveness of PLC-based automation in improving positioning accuracy, production speed, and overall usability in manufacturing environments.

Abstract

In critical care, the co-administration of intravenous drugs often leads to physical incompatibilities, resulting in harmful precipitates. This study evaluated the nature of drug-induced precipitation in terms of size, shape, and quantity. Twelve drugs previously reported to be incompatible were tested with infusion fluids. Particle detection was conducted using an Olympus CX41 microscope with a 1 µm detection limit, enhanced by darkfield microscopy for better sensitivity. Particle size was analyzed using Feret’s diameter via the Optilab imaging system. Precipitates ranged from 5–150 µm, with smaller particles (<10 µm) seen in furosemide and subvisible particles (10–50 µm) in cefotaxime, chloramphenicol, and paracetamol. Visible particles were noted in acyclovir, ampicillin, meropenem, phenobarbital, and phenytoin. Most macro-precipitates were acicular, while micro-precipitates tended to be irregular. Particle counts ranged from 80 to 2,000 particles/mL. The findings highlight the clinical risk of particulate contamination due to drug incompatibilities, emphasizing the need for careful medication management.

Abstract

Managing wastewater from dyeing industries has become a significant challenging issue in the world. Various methods have been reported in the literature to treat these effluents with adsorption and photocatalysis emerging as popular methods due to their low cost, simplicity and effectiveness in reducing the quantity of pollutants before they enter water bodies. This review summarizes key findings of the recent few years on the application of metal oxide nanoparticles in wastewater treatment. Adsorption alone is effective for removing pollutants even in very trace amounts, but it does not break down into eco-friendly products. Photocatalysis, on the other side, needs the adsorption of contaminants onto the catalyst surface to initiate degradation. Thus, this review provides a discussion on the mechanism of adsorption, as well as photocatalysis.

Abstract

Fatty acids are vital components of biological membranes and key metabolic fuels in living organisms. Their composition influences the nutritional and functional properties of food. This study aimed to compare the fatty acid profiles of groundnut and cashew nut to determine their nutritional value. Using the AOAC in 2000 method, samples of both nuts were analysed through gas chromatography. Groundnut oil was found to contain higher concentrations of oleic acid (46.99%) and linoleic acid (9.91%), while cashew nut oil had higher levels of palmitic acid (22.88%) and lauric acid (18.98%). The total fatty acid concentration in groundnut exceeded that of cashew, indicating that groundnut is richer in fatty acids overall. This comparison highlights the superior fatty acid content of groundnut, which could inform nutritional recommendations and food formulation strategies. The findings contribute to food science literature by emphasizing the value of groundnut as a high-fatty-acid food source.

Abstract

This study investigates the techno-economic feasibility of producing ecoenzymes from wet organic waste, supported by a bibliometric analysis of relevant global research trends. Spanning a 20-year projection, the study evaluated the production costs, potential profitability, and market pricing of ecoenzymes as an environmentally friendly product. Results indicated that even small-scale, home-based production was economically viable, requiring a minimal daily capital investment of $0.27 (or approximately $80,625 annually). With a selling price of IDR 200,000 per kg, the projected annual revenue was IDR 400,000,000. Notably, the return on investment was achieved within the first three years. The bibliometric analysis highlighted a growing global focus on sustainable waste-to-product conversion. The novelty of this study lied in its application of techno-economic modeling to a previously underexplored product, ecoenzymes from wet organic waste. The findings contribute to multiple Sustainable Development Goals (SDGs), especially SDG 11 (Sustainable Cities), SDG 12 (Responsible Consumption and Production), and SDG 13 (Climate Action).

Abstract

This study implements the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method to evaluate and mitigate occupational risks in the manufacturing construction sector. A bibliometric analysis reveals a growing yet insufficient number of studies applying structured risk control frameworks like HIRADC in industrial settings, particularly in developing countries. Using a descriptive approach, data were collected through field observations, interviews, and document analysis. Seven hazards were identified, resulting in five low-risk and two moderate-risk classifications using a probability–severity matrix. Control measures were implemented following ISO 45001:2018 standards, including engineering controls, administrative actions, and personal protective equipment (PPE). The results demonstrate that HIRADC enhances workplace safety awareness and reduces risk levels. This study contributes a practical safety framework for manufacturing environments while reinforcing the relevance of SDG-aligned and bibliometrically justified research in occupational health.

Abstract

This study investigates the improvement of thermal performance in smooth and ribbed double-pipe heat exchangers using titanium-based nanofluids. Titanate nanoparticles and nanotubes were synthesized and dispersed in water through a two-step method to ensure stable nanofluid mixtures. Experimental trials were conducted at varying concentrations and flow rates to evaluate temperature difference, heat transfer rate, coefficient, and efficiency. Results indicate a consistent performance increase in ribbed configurations, with titanium nanotubes outperforming their nanoparticle counterparts. This enhancement occurs because the ribbed geometry promotes turbulence while the nanotube’s morphology increases thermal conductivity and energy interaction with the fluid. The combination of structural design and nanofluid science enhances energy efficiency in heat exchanger systems. These findings support the development of more effective thermal systems through the integration of nanotechnology and mechanical design, aligning with advancements in science and engineering education.
