First-Principles calculations to investigate structural, mechanical, electronic, optical and thermoelectric properties of RuNbAs and RuNbSb Half-Heusler alloys

This study presents a first-principles investigation of the structural, thermodynamic, mechanical, electronic, optical and thermoelectric properties of RuNbZ (Z = As, Sb) half-Heusler (HH) alloys using density functional theory (DFT). Structural optimization, negative formation e...

Trends and treatment outcomes of tuberculosis and associated factors among patients in Dawe Kachen District: a five-year health facility registry analysis

Ethiopia is among the countries with a high tuberculosis (TB) burden and has implemented the World Health Organization (WHO)-recommended Directly Observed Treatment Short-Course (DOTS) strategy since 1991. In Dawe Kachen District, a previous retrospective study (2013–2018) assess...

Woody species diversity and dispersal dynamics in Biyo Forest, Central Ethiopia: a conservation perspective

Seed dispersal shapes species composition, regeneration, and long-term resilience of dry Afromontane forests. In Ethiopia, there is limited information on how woody species disperse and recruit. Biyo Forest, a protected exclosure in central Ethiopia, offers an opportunity to stud...

Determinants of treatment interruption among patients with multidrug-resistant tuberculosis in Addis Ababa using an unmatched case-control study

Multidrug-resistant tuberculosis (MDR-TB) requires prolonged, complex regimens frequently associated with substantial adverse effects, making treatment interruption a major barrier to successful outcomes. Interruption may increase the risk of mortality, acquired drug resistance,...

Modeling Rainfall-Runoff Dynamics Using HEC-HMS: Case of Gololcha Watershed

ABSTRACT Accurate simulation of rainfall–runoff processes is essential for flood prediction and sustainable water resources management, particularly in watersheds that exhibit high seasonal variability in streamflow. The Gololcha watershed in the Wabe Shebele River Basin of Ethio...

SYNTHESIZING BIO-FERTILIZER AND EVALUATING IT'S PHYSICO-CHEMICAL PARAMETERS.

<strong>ABSTRACT</strong> <em>Bio-fertilizers add helpful microbes that aid in nitrogen fixation, nutrient recycling, and phosphorous breakdown. Since there is a growing desire for farming methods that donot hurt the environment, bio-fertilizers are a good, earth-friendly alterna...
