Boosting Automotive Engine Performance: Exploring the Potential of Fuel Additives on P.M.S and A.G.O
Nnadikwe Johnson*, Iheme Chigozie, Chinemerem Joy Johnson, Ibe Raymond Obinna, Akujuru Kelvin
This research aims to optimize the performance of PMS and AGO in automobile engines by leveraging fuel additives. To achieve this, the study focuses on purifying PMS and AGO by removing impurities and enhancing their octane and cetane ratings. The purification process involves a three-step procedure: firstly, concentrated sulfuric acid, hydrogen peroxide, and acetic acid are added to elimina
Construction and Performance Evaluation of Locally Built PVC-Based Biogas Digesters
M. I. Ishaq*, I. Halliru, D. B. Olaoye, J. D. Barka, Y. Ibrahim
This study investigated the construction and performance of three locally-built biogas digesters designed to produce biogas from various organic material combinations. Conducted during the harmattan season with suboptimal temperatures (below 30°C) and lacking a stirrer mechanism, the experiment faced challenges resulting in low biogas yield within the initial 14-day retention period. A 7-day
The Threats of Electronic Waste on Water Resources in Urban Tanzania: A Case Study of Dar es Salaam, Mwanza, and Arusha
Muhajir Mussa Kwikima*
This study investigated the impacts of e-waste on water quality in three major cities of Tanzania - Dar es Salaam, Mwanza, and Arusha. Water samples were collected from sites proximate to residential-cum-e waste hotspots and analyzed for physicochemical parameters as well as concentrations of priority toxic heavy metals and organic pollutants. Results showed pH, conductivity, TDS, and turbidi
Biochar Innovation: Improving Industrial Effluent Quality Through Activated Plantain Biochar for Particulate Matter Adsorption
Nnadikwe Johnson*, Iheme Chigozie, Chinemerem Joy Johnson, Ibe Raymond Obinna, Akujuru Kelvin
This innovative study explores the potential of plantain peel, a readily available and sustainable material, for the effective removal of particulate matter from industrial effluents. Through a series of batch experiments, the researchers investigated the optimal conditions for absorption, including pH, contact time, adsorbent dose, and particle size. The findings reveal that the adsorbent a
Effect of Additional Capacitor and Diode to A Single-Ended Primary Inductor Converter (SEPIC) Dc-Dc Converter For Offgrid System Based Photovoltaic (PV) Applications
Uzaifa Isah*, Abdu Yunusa, M.H. Ali
For a stand-alone based photovoltaic (PV) applications, this article analyzes the implications of adding certain components to the single-ended primary inductor converter (SEPIC). A capacitor and a diode were added to the new topology's design. The added capacitor was used to boost and shaped the signal coming out from the power switch while the diode serves as a reverse back diode. The sugg
