Combined photovoltaic and thermal enhancements of solar photovoltaic system using SiO2 and Al2O3 nanoparticle-enhanced paraffin wax phase change material

This study addresses the reduction in electrical efficiency and power output caused by elevated operating temperatures in Solar Photovoltaic Thermal (SPVT) panels by implementing an effective cooling approach to enhance energy yield and overall system performance. The study exper...

Challenges and needs of people living with diabetes in self-management in Ethiopia: A qualitative exploration

Abstract Background Diabetes is unique due to its cross-cutting nature, impacting multiple organ systems and increasing the risk for other communicable and non-communicable diseases if not managed properly. Managing diabetes involves frequent blood glucose measurement, medication...

Synergistic experimental and ANN-based prediction of mechanical properties of basalt fiber reinforced high-strength concrete

This research focuses on how basalt macrofibers and microfibres affect the durability and Mechanical properties of M60 high-strength concrete. Compressive, split tensile, flexural strength, and acid resistance tests were employed to assess the performance of fiber-reinforced conc...

Progress in reaching zero-dose children: analysis of population-modifiable risk factors and inequity trends in low- and lower-middle-income countries

Zero-dose (ZD) children remain concentrated in low- and lower-middle-income countries (LLMICs) and are a major focus of the Immunization Agenda 2030 (IA2030), which aims to halve their number by 2030. Despite this commitment, progress has stalled in many high-burden settings. Thi...

Anopheles larval ecology and physicochemical characterization of larval habitats in Dire Dawa: an area colonized by Anopheles stephensi in Eastern Ethiopia

Abstract Background Understanding mosquito larval ecology is crucial for effective vector control strategies. While much is known about Anopheles larval habitat distribution, the impact of landscape (urban vs. rural) on Anopheles stephensi larval distribution and population dynam...

Effects of hydraulic retention time and indigenous substrates on the treatment performance of constructed wetlands planted with Cyperus alternifolius for healthcare wastewater remediation

Due to persistent contaminants in healthcare wastewater (HWW), conventional treatment technologies are ineffective. Yet few studies utilize local materials, and none have compared pumice versus ignimbrite substrates with Cyperus alternifolius in horizontal subsurface flow constru...

Building the toolkit to address malaria resurgence and radical cure of vivax malaria in Ethiopia: a meeting report

Abstract Ethiopia has experienced a substantial resurgence in malaria in recent years, with increasing case numbers and a growing contribution of Plasmodium vivax in several regions. At the same time, new evidence supporting improved radical cure strategies, including high-dose p...
