This study evaluates the influence of Ocimum lamiifolium leaf extract (OLE) concentration on
the green synthesis of zinc oxide nano particles (ZnO NPs) and their performance as an Electron
Transport Layer (ETL) in ...
Dye-sensitized solar cells (DSSCs) have attracted significant attentions as a cost-effective and environmentally friendly alternative to conventional silicon-based photovoltaics. However, the widespread application of ...
The demand for low power, low voltage devices is increasing at a faster rate as a
result of wider implementation of smaller-sized, portable, and hand held devices in
the telecommunication and entertainment industries. ...
Background: Placental malaria (PM) represents a significant public health burden for both
pregnant women and their fetus. The diagnosis of malaria in Ethiopia primarily relies on blood
film microscopy using stained ...
Solar radiation, the electromagnetic energy emitted from the Sun, is a fundamental driver
of Earth's weather and climate systems and represents a vast, clean energy source. Global solar
radiation (GSR) is the total ...
Advancements in technology and e-commerce have made credit cards a common payment
method, reducing reliance on cash. However, this shift has also led to a rise in online fraud,
causing significant financial losses. ...
Critical thinking and problem-solving are essential 21st-century skills; however, they remain underdeveloped in Ethiopian secondary education, where biology instruction is often dominated by rote learning, low academic ...
Predicting volatility and correlation in financial assets is crucial for assessing financial
risk and achieving effective portfolio diversification. However, conventional econometric
models used for forecasting volatility ...
This dissertation presents a theoretical investigation of magnetohydrodynamic (MHD)
flow of non-Newtonian nanofluids over stretching surfaces, with particular focus on the
combined effects of Hall currents and ion slip ...
Ciprofloxacin (Cpro) and Norfloxacin (Nor) are drugs belonging to the fluoroquinolones class, commonly used to treat bacterial infections of humans and animals. However, improper use, unmetabolized excretion, and overuse ...
Fascioliasis, a snail-borne zoonotic disease recognized by the World Health Organization
as a neglected tropical disease, significantly impacted human and livestock
health and economies, affecting over 700 million animals ...
In this dissertation, different parameter uniformly convergent numerical methods
are proposed to solve time-fractional singularly perturbed convection-diffusion
equations with/without delay in the time variable. The ...
Peste des petits ruminants (PPR) is a highly contagious viral disease that severely threatens the
livelihoods and food security of smallholder farmers across Africa, the Middle East, and Asia,
including Ethiopia, where ...
Lichens are symbiotic organisms consisting of fungi and algae with notable bioactive potential.
This study optimized extraction conditions and quantified total phenolic content (TPC), total
flavonoid content (TFC), and ...
This dissertation investigates heat and mass transfer in two- and three-dimensional electrically
conducting non-Newtonian hybrid nanofluid flow over a stretching surface embedded in a porous
medium. The Tiwari–Das and ...
Solar radiation, the electromagnetic energy emitted from the Sun, is a fundamental driver of Earth's weather and climate systems and represents a vast, clean energy source. Global solar radiation (GSR) is the total amount ...
This dissertation explores the spatiotemporal variations of ionospheric Total Electron
Content (TEC) and the characteristics of Equatorial Plasma Bubbles (EPBs)
over East Africa, based on a comprehensive analysis of ...
In this dissertation, fitted operator and fitted mesh numerical methods are developed for singularly perturbed
parabolic differential and differential-difference equations with boundary turning points. These problems ...
This study investigated the effectiveness of integrating Conceptual Change Texts (CCTs) with
systematic formative feedback to minimize Grade 10 students‟ misconceptions and enhance their
conceptual understanding of ...
This dissertation focuses on the formulation and analysis of various fitted numerical methods for
the solution of singularly perturbed parabolic diffusion-type problems characterized by boundary
layers, both in the ...
