Estimation of Population Mean Using Three-Stage Optional RRT Model in the Presence of Measurement Errors under Stratified Two-Phase Sampling
(2023)
In the present study, the problem of estimation of the finite population mean of a sensitive study variable using the three-stage optional Randomized Response Technique (RRT) model under measurement errors is addressed. A ...
Socio-Cultural Practices on the Use of Beetle Grubs as Food and Feed in Western Kenya
(Scientific Reports, 2023-05-13)
We examined the socio-cultural practices on the use of beetle grubs as food and feed in western Kenya by interviewing 211 randomly selected households and conducting seven focus group discussions in Bungoma, Kakamega, ...
Formulation of a Four-Species Food Web System with Prey Refuge and Holling Type III Functional Response
(World Wide Journal of Multidisciplinary Research and Development, 2023-01)
The coexistence of interacting biological species is a vital issue for the management of existing resources and the prediction of the long-term survival of each species. Many species become extinct due to several factors ...
Numerical Analysis of Prey Refuge Effects on the Stability of Holling Type III Four-Species Predator Prey System
(Scientific Research Publishing, 2023-06-29)
The dynamic behavior of a multi-species system that includes a prey refuge and a Holling type III functional response is examined in this work. The pre-requisites for the presence of the equilibrium points, as well as their ...
Choi Matrices of 2-positive Maps on Positive Semidefinite Matrices
(Asian Research Journal of Mathematics, 4/27/2020)
Several investigations have been done on positive maps on their algebraic structures with more emphasis on completely positive maps. In this study we have described the structure of the Choi matrices for 2−positive maps ...
Integrating Black Soldier Fly (Hermetia illucens) Larvae Meal in Aquaponics System for Lettuce (Lactuca sativa) Production
(East African Journal of Agriculture and Biotechnology, 2024)
The adoption of aquaponics systems faces challenges due to the high cost of fish feed, lack of sustainability, and reliance on fishmeal as a primary input. One potential solution to replace fishmeal is the use of black ...
Evaluating Predictive Value of Schistosoma mansoni Prevalence and Infection Intensity in School-Age Children in Estimating Community-Wide Prevalence in Siaya County, Western Kenya
(medRxiv preprint, 2024-02-20)
Background
Various milestones have been set targeting the elimination of schistosomiasis with the vision of “a world free of schistosomiasis” including the 2020 and 2025 goals. Despite the increased control and prevention ...
Diversity of endophytic bacteria Isolated from Leguminous Agroforestry Trees in Western Kenya
(AMB Express, 2024-02-08)
Plants have diverse and vast niches colonized by endophytic microorganisms that promote the wellbeing of host plant. These microbes inhabit internal plant tissues with no signs of ill health. Bacterial endophytes from many ...
Density and Dentability in Norm-Attainable Classes
(Elsevier Ltd., 2024-03-18)
We establish the norm-denseness of the norm-attainable class $NAB(H)$ in the Banach algebra $B(H)$, which consists of all bounded linear operators on a complex Hilbert space $H$. Specifically, for every $O \in NAB(H)$ and ...
