Integer programming (IP) is a branch of Mathematical optimization where the objective is to
find the best solution from a finite set of feasible solutions, subject to a set of constraints, with
the decision variables ...
This thesis examines a prey-predator system subjected to harvesting, with a focus on the
influence of effort allocation between prey and predator harvesting. Using a modified deterministic mathematical model, we have ...
Ecological communities face significant challenges from human-induced pressures such as
overharvesting and environmental pollution, threatening the stability and coexistence of
two-species systems. This thesis investigates ...
This study focuses on modelling landslide susceptibility in the Mantsa river catchment Dawro
Zone, southwestern Ethiopia, utilizing statistical approaches, specifically frequency ratio and
logistic regression. A comprehensive ...
Typhoid fever is a communicable disease caused by the bacteria Salmonella typhi. The disease is
of a significant health concern in most developing countries especially Ethiopia. Typhoid fever
remains a significant public ...
Tuberculosis (TB) remains a major public health challenge in Ethiopia. Evaluating treatment
outcomes and identifying associated risk factors is critical to improving TB control efforts.
This study aimed to assess treatment ...
Rabies is a viral disease that affects all warm-blooded animals. It is widely spread in many
regions of the world. Human rabies, transmitted by dogs is an important public health issue
in Ethiopia. The virus spreads ...
Hypertension is one of the main public health challenges in the current world including developing
countries. Despite being a main public health issue there is no current evidence on the status of
hypertension prevalence ...
Intestinal parasitic infections (IPIs) remain a significant public health concern, especially in
low-resource settings where poor sanitation, limited access to clean water, and inadequate
health education facilitate their ...
This investigation studies the concentration and optical properties of chlorophylls and
carotenoids in two edible Moringa leaves (Moringa oleifera and Moringa stenopetala)
located in three woreda/district sites in the ...
Teff (Eragrostis tef) is Ethiopia‘s treasured cereal crop, valued for its nutritional quality and
central role in making injera. Despite its cultural importance, the microbial processes underlying
its fermentation are ...
In this work, we study a three-species plankton-fish system in a polluted environment with
linear harvesting and pollution reduction efforts. We considered a deterministic model
consisting of a system of three nonlinear ...
This thesis examines a predator-prey system incorporating a strong Allee effect on the prey
population, environmental pollution, and a combined strategy of harvesting and pollution
reduction efforts. A modified deterministic ...
Ecosystems provide essential services vital to human well-being. This study examined land
use/land cover changes over three decades and their impact on ecosystem service values of the
Hoto area, South Ethiopia. Data ...
Tuberculosis (TB) is a serious global health issue, causing significant illness and death. Its impact
is high in developing countries including Ethiopia. Assessing the existing trend, prevalence and
associated risk factors ...
The human-wildlife conflict is a global concern, and developing countries face it more,
though in different manifestations. In the study area, Omo National Park, wild animals
and the local community compete for resources, ...
Fixed point theory is a fundamental method in the solution analysis of mathematical problems arising in nonlinear differential equations for which it may appear extremely difficult
to find an explicit solution. This ...
Alien invasive species significantly impact the growth rate and yield of native fish populations in harvesting systems. Reducing invasive species is expected to alleviate pressure on
native fish, enhancing both their stock ...
The Ulam-Kakutani Collatz Conjecture
The Ulam-Kakutani Collatz conjecture explores the behavior of sequences generated
by the Collatz function, defined as follows: For any positive integer n,
f(n) =

The present study aims to delineate the groundwater potential mapping by using geospatial
technology through based Multi-criteria decision (MCD) methods in the Laska catchments, Omo
Basin, Southern Ethiopia. Groundwater ...
