Isolation of Haloalkaliphilic Fungi from Lake Magadi in Kenya
(Heliyon, 2020)In this study we explored the cultivable fungal diversity in Lake Magadi and their secondary metabolite production. Isolation was done on alkaline media (Potato dextrose agar, Malt extract agar, Oatmeal agar and Sabouraud ... -
A Deterministic Model Of HIV Transmission Between Two Closed Patches Incorporating The Monod Equation
(International Institute for Science, Technology and Education (IISTE), 2019-06)Among other factors, migration has significantly contributed to the spread of HIV. Recent studies have revealed that new infections occur along major transport corridors and truck-drivers have overall higher prevalence ... -
Effects of Temperature Dependent Viscosity and Viscous Dissipation on Fluid Flow Past a Moving Flat Plate
(International Journal of Innovative Science, Engineering & Technology (IJISET), 2016-12)In this study, the effects of temperature dependent viscosity and viscous dissipation on fluid flow over a moving flat isothermal plate have been investigated. A steady two dimensional laminar boundary layer flow of ... -
Modelling Miraa Addiction like a Disease Incorporating Voluntary Quitting
(Journal of Advances in Mathematics and Computer Science, 2017)This study presented a deterministic model of miraa addiction based on three compartmental classes incorporating miraaspecific attributes as well as the aspect of voluntary quitting. Our model was based on SIS ... -
Turbulent Natural Convection in an Enclosure at Varying Aspect Ratio
(International Institute for Science, Technology and Education (IISTE), 2017)Energy transfer mechanism in most technical flows is through turbulent natural convection due to low viscosity of the fluids used in technical applications. Consequently, there is need to establish the parameters that ... -
Turbulent Natural Convection in an Enclosure at Varying Rayleigh Number
(International Journal of Science: Basic & Applied Research, 2017)Most fluids used in technical applications are of low viscosity; hence, fluid flows encountered in engineering applications are mostly turbulent. Parameters that influence the distribution of the ... -
Synergistic Evaluation of Selected Plant Extracts on Potency of Pyrethrins against the Maize Weevil, Sitophilus zea-mais (MOTSCH.)
(Merit Research Journals, 2020-11)The interest in utilization of botanical insecticides, particularly essential oils have become increasingly relevant in the control of insect pests. Many plant products and their bioactive compounds with repellent, antifeeding ... -
Screening of Plant Extracts Possessing Methylenedioxyphenyl (MDP) Group as Potential Synergists in Insecticide Formulations using the Maize Weevil, Sitophilus Zea-mais (Motsch.)
(Merit Research Journals, 2020)Synergists are compounds that are either negligibly toxic or non-toxic to insects when applied on their own, but enhance the efficacy of an insecticide. Many insects are able to detoxify insecticide molecules and survive ... -
Velocity Profiles of Unsteady Blood Flow through an Inclined Circular Tube with Magnetic Field
(Journal of Advances in Mathematics and Computer Science, 2017)The present paper is devoted to study the flow of incompressible viscous, electrically conducting fluid (blood) in a rigid inclined circular tube with magnetic field. The blood is considered to be Newtonian fluid and the ... -
Kinetics of the Alkaline Phosphatase Catalyzed Hydrolysis of Disodium p-Nitrophenyl Phosphate: Effects of Carbohydrate Additives, Low Temperature, and Freezing
(PubMed, 2004)The alkaline phosphatase catalyzed hydrolysis of disodium-p-nitrophenyl phosphate was studied in four model systems comprising sucrose, maltodextrin, carboxymethylcellulose (CMC), and CMC-lactose in a temperature range of ... -
Green Synthesis of Silver Nanoparticles by Rivina Humilis Leaf Exact to Tackle Growth of Brucella Species and other Perilous Pathogens
(Elsevier, 2020)Novel approaches are obligatory to treat chronic intracellular bacterial infectious diseases like Brucellosis specifically, are very complicated to deal with. The aim of the study to take upon nanotechnology approach to ... -
Nutritional Diversity of Leafy Amaranth Species grown in Kenya
(Elewa Bio Science, 2014)Objectives: Despite the availability of many species of amaranth in Kenya, there is inadequate information on their nutritional diversity and how they can be best used in mitigation of malnutrition. Hence, this study was ... -
In Vitro Production of Trichothecenes and Zearalenone by Fusarium Isolates from Equatorial Barley (Hordeum vulgare l.) grown in Kenya
(African Scholarly Science Communications Trust, 2012)ABSTRACT Fusarium head blight (scab) is a devastating disease of wheat and barley throughout the world. The disease has been reported worldwide wherever cereals are grown, cutting across diverse ecological and geographical ... -
Physicochemical and Antimicrobial Properties of Post-Synthesis Betanin and Chitosan Oligosaccharide functionalized Silver Nanoparticles
(Springer, 2020)Size uniformity and defined surface coating are important parameters for the biological properties of silver nanoparticles (AgNPs). Green synthesis uses biomolecules either in pure form or plant extracts as both reductants ... -
