Spatiotemporal variability and trends of precipitation, temperature, and evapotranspiration in the Muger sub-basin of the Abbay basin Ethiopia

Abstract This study used time series data from 1980 to 2022 to investigate spatiotemporal changes and trends of precipitation, temperature, and evapotranspiration in Muger sub-basin. The coefficient of variation (CV), precipitation concentration index (PCI), and seasonality index...

Collateral damage of the EU deforestation regulation on commodity supply chains in cocoa, coffee, palm oil, soy, and cattle value chains

The European Union Deforestation Regulation (EUDR), formally adopted as Regulation (EU) 2023/1115, seeks to reduce global deforestation by requiring deforestation-free and legally compliant supply chains for commodities including cocoa, coffee, palm oil, soy, cattle, wood, and ru...

A systematic literature review of blue ocean strategy (BOS) as a reconstructive approach to the competitive advantage

This research conducted a systematic literature analysis of empirical studies published between 2019 and 2025 to investigate the contemporary function of blue ocean strategy (BOS) in attaining competitive advantage. In accordance with PRISMA 2020 guidelines, the document consolid...

The impact of blue ocean strategy’s ERRC grid on community engagement in higher education at Puntland state university in Somalia

The study assesses the extent to which Eliminate-Reduce-Raise-Create (ERRC) dimensions in the blue ocean framework associate with community engagement at Puntland State University (PSU) in Somalia. Specifically, it evaluates the effectiveness of the ERRC grid in strengthening uni...

Machine learning for early prediction of preterm birth

Abstract Background Preterm birth (PTB), defined as delivery before 37 completed weeks of gestation, remains a major cause of neonatal mortality and long-term morbidity worldwide. Conventional risk assessment strategies, including cervical length measurement and biomarker-based s...

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...

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...

Evaluation of undercut depth for flexible pavement on unsuitable tropical red soils using finite element method

Due to the lack of a reliable classification system and inadequate evaluation of their engineering properties, undercut depth is recommended for tropical red soils when used in flexible pavement construction. The aim of this study is to determine the ideal depth for subgrade unde...

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...

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...

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...

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...

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...
