We propose and analyze a compartmental nonlinear deterministic mathematical model for the typhoid fever outbreak and optimal control strategies in a community with varying population. The model is studied qualitatively ...
Using military-type strategies and equipment to conserve wildlife, also known as militarized conservation, is highly contested. In
sub-Saharan Africa (SSA), one acutely controversial aspect of militarized conservation is ...

This study investigated the stochastic price dynamics of green grams in Kitui County, Kenya, aiming to analyze and predict price movements using a Markov chain model. Employing monthly price data from January 2012 to ...
Biological control agents heavily rely on volatile cues for host location and can be an important component of managing pests through habitat management-based strategies that enhance trophic interactions. This study aimed ...

There is an alarming increase of cancer cases alongside an increased pesticide use in agriculture in Kenya. This has raised concerns about possible links between pesticide exposure and cancer incidences. This study ...
This study investigated the influence of principals' management practices of institutional working conditions on students' academic performance in public day secondary schools in Kitui West Sub-County, Kenya. The study ...
The adoption of Artificial Intelligence (AI) in customer engagement is transforming enterprise growth in Kenya by enhancing service delivery, marketing strategies, and decision-making processes. This study examines the ...
Mathematical modeling has enabled epidemiologist to understand best the dynamics of infectious diseases, their impact and future predictions on their transmission and existence. Deterministic Susceptible–Vaccinated–Expos ...
Associated with every commuting m-tuples of operators on a complex Hilbert space X is its Aluthge transform. In this paper we show that every commuting m-tuples of operators on a complex Hilbert space X and its Aluthge ...
