On Norm Estimates for Derivations in Norm-Attainable Classes
(Eur. J. Math. Anal, 2023)
In this note, we provide detailed characterization of operators in terms of norm-attainability and norm estimates in Banach algebras. In particular, we establish the necessary and sufficient conditions for norm-attainability ...
Vulnerability of Nyabarongo River Water Abstraction to Climate Change in Rwanda
(International Journal of Environmental Sciences, 2023-02-13)
Purpose: Climate change in Rwanda is a great challenge resulting from increased temperature and causing abnormal variability in weather variables and threatening the socio-economic welfare of human beings. Water resources ...
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 ...
Negative Magnetization and Inverse Exchange Bias Effect Induced By Modulating the Relative Proportion of Mn in Gd 2 Co 2−Xmnxo6 Perovskites
(Physical Review, 2023-06-28)
The magnetic properties of Gd 2 Co2−x Mnx O6 by modulating the relative proportion of Mn are experimentally investigated in this paper. The experimental results indicated that an intrinsic effect of negative magnetization ...
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, ...
Comparative Analysis of Sars-Cov-2 Detection Methods Using Stool, Blood, and Nasopharyngeal Swab Samples
(The Pan African Medical Journal, 2023-09-14)
As a public health policy, the ongoing global coronavirus disease 2019 vaccination drives require continuous tracking, tracing, and testing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Diagnostic testing ...
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 ...
