Modeling HIV/AIDS Co Infection with Malaria and Tuberculosis: The role of treatment and counseling
(2018-05)HIV/AIDS remains one of the leading causes of death in the world with its effects most devastating in Sub Saharan Africa due to its dual infection with opportunistic infections especially malaria and tuberculosis. This ... -
Modeling the Impact of Soil Porosity on Nitrate Leaching to Groundwater Using the Advection Dispersion Equation
(2019-04)Nitrogen is a vital nutrient that enhances plant growth which has motivated the intensive use of nitrogen-based fertilizers to boost crop productivity. However, Pollution by nitrate is a globally growing ... -
Modifying Surber sampling technique increases capture of freshwater crabs in African upland streams. Inland Waters. 2:11-15
(2017-04-03)We compared 2 methods for sampling the freshwater crab Potamonautes odhneri (Colosi) in Kenyan streams: standard Surber sampling, in which a sample is taken over a period of several minutes; and rapid Surber sampling, ... -

(Current Research in Environmental & Applied Mycology, 2016-03-30)Mushrooms of the genus Auricularia, generally termed wood ear mushrooms are in high demand in Western Kenya due to their numerous medicinal and nutritional properties. Interventions to characterize and conserve the native ... -
A Multi-Faceted Approach to Mobile Agent Security
(2015-06)Mobile agents are increasingly becoming popular in the development of current distributed applications. However, the mobility and autonomy factors of mobile agents present a host of security challenges in a ... -
Near Surface Anomaly Depth Estimation Using Downward Continuation
(2018-10)Depth estimation in gravity survey is very important in mineral prospecting. It does not only inform the choice of the optimal point for mineral exploration but also very important in analyzing economical viability of the ... -
Nephrotoxicity effects of Khat (Catha edulis) on mice when administered orally
(2017-03)Renal problems are currently on increase worldwide. Some factors suspected to be the cause of the renal problems are drug abuse. Hence, this study investigated possible renal toxicity effect of ... -
NEW METALLOCHROMIC INDICATORS FOR COMPLEXOMETRIC TITRATION OF COPPER (II) IN PRESENCE OF INTERFERING SPECIES
(Life Science Informatics Publications, 2020-09)Six hydroxytriazenes has been introduced as a metallochromic indicator in the complexometric titration with EDTA and applied successfully to the titration of copper (II). A direct method of titration of Cu (II) with EDTA ... -

Norm- Attainability of Generalized Finite Operators on C*- Algebra
(Modern Scientific Press Company, 2022)Norm -attainability of elementary operators on Hilbert and Banach spaces have been Characterized by many mathematicians. However, there is little information on Normattainability of generalized finite operators on C*-algebra. ... -
A note on quasi-similarity of operators in Hilbert spaces
(2015-01)In this paper we introduce the notion of Quasi-similarity of bounded linear operators in Hilbert Spaces. We do so by defining a quasi-affinity from one Hilbert Space H to K. Some results on quasi-affinities are also ... -
