SYNTHESIS AND CHARACTERIZATION OF NOVEL TBAF-PROMOTED DESILYLATION OF FLUOROGENIC 3-CYANO-7-HYDROXY-4-METHYLCOUMARIN DERIVATIVES AS POTENTIAL RAPID FLUORIDE DETECTORS IN POTABLE WATER
(University of Eldoret, 2021)
Over the years, Fluoride has been identified as a contaminant of great global concern on drinking water safety. The need to prevent the population from consuming higher fluoride content in water lies in fluoride sensing. ...
THE POTENTIAL OF WATER FROM KIPLOLOK BUBBLING SPRINGS IN NANDI COUNTY FOR USE AS NATURAL CARBONATED MINERAL WATER
(University of Eldoret, 2021)
The demand for carbonated water in Kenya, just like the rest of the world, is on the rise, owing to increasing lifestyle diseases like obesity, which requires that for a healthy lifestyle a lot of carbonated water, should ...

(African Journal of Education, Science and Technology, 2021)
An investigation was carried out to ascertain the effectiveness of experimental
approach on students’ application of moment of force concepts in Physics in secondary
schools in Marakwet West Sub-county, Elgeyo Marakwet ...
Water Defluoridation by Adsorption Using Aluminium Modified Chicken Feathers
(African Journal of Education, Science and Technology, 2021)
Sufficient fluoride (F-
) ingestion through food, soil and water is necessary for the
development of healthy bones and teeth while excess of it results in dental, skeletal and
soft tissue damage. To protect people ...
Insecticidal Activity of Chrysanthemum Cinerariifolium & Allium Sativa Natural Oils against Prostephanus truncatus
(African Journal of Education, Science and Technology, 2021)
The larger grain borer (Prostephanus truncatus) is one of the most destructive
post-harvest pest that affects maize and other crops like cassava. Synergists are
substances added to pyrethrin increase efficacy and also ...

(BMC Infectious Diseases, 2021)
Background: Diarrhoea is a common cause of mortality and morbidity in children under five years old. In Kenya, it
has a 21% case fatality with Enteropathogenic E. coli, Campylobacter jejuni, Shigella spp. and Salmonella ...
Potable Water Fluoride Rapid Detection Based on TBAF Desilylation by a Novel Fluorogenic 7-O-tert-butyldimethylsilyl-3-cyano-4-methylcoumarin Compound
(African Journal of Education, Science and Technology (AJEST), 2021-05)
This article reports the synthesis and properties of a novel fluoride detector, 7-O-tertbutyldimethylsilyl-3-cyano-4-methylcoumarin, which emits a lavender blue fluorescence in aqueous solution when fluoride ions are ...
Modeling Key Drivers of Under-Five Child Malnutrition in Marsabit County, Kenya: Application of the Logit Model
(Asian Journal of Probability and Statistics, 2021-04)
Malnutrition remains one of the major problems in developing countries affecting both adults and children
under 5 years. The use of binary logistic regression model was employed, and parameters of interest
estimated. ...
The effect of a difference in angle in two lateral inflow channels on the main channel's velocity
(International Journal of Statistics and Applied Mathematics, 2021-04)
In this study, we examined the flow from two lateral inflow channels in a man-made open rectangular
channel of an incompressible Newtonian fluid. The influences of the angles as it varies directly
proportional to each ...
Optimization of Split-Plot Design in the Context of Mixture Process Variable Settings
(Asian Journal of Probability and Statistics, 2021-04)
In the presence of process variables, a mixture design has become well-known in statistical modeling due to
its utility in modeling the blending surface, which empirically predicts any mixture's response and serves as
the ...
