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
Expansion of Rural Settlement on High Quality Arable Land in Northern Province a Case Study of Musanze District
Pierre Damien Iraguha*, Tresor Hirwa
Settlement increase triggered by escalating urbanization is a critical element to the diminishing arable land globally. In Rwanda more people are concentrating in urban areas while rural population shrinks exponentially due to various factors, but unfortunately arable land continues decreasing. Rural and urban settlement especially in northern Rwanda expands into arable land, which in turn d
Off-the-Shelf Infrastructure for Innovative Mobile Communication Services in Angola
Hermenegildo Marinha Cassoada*, Ngombo Makaya Armando
VoIP technology implementation over 802.11 standard in corporate environment is a challenge when it comes to ensuring Quality of Experience (QoE) before and during the handoff process. To this regard, we have developed a solution leveraging off-the-shelf enablers to insure high-quality mobile VoIP service with in a wireless Local Area Networks (LAN). Our case study has been assessed via simu
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
