Modeling the Effect of Binding Kinetics in Spatial Drug Distribution in the Brain
(Hindawi, 2021-07-05)A 3-dimensional mathematical model is developed to determine the effect of drug binding kinetics on the spatial distribution of a drug within the brain. The key components, namely, transport across the blood-brain barrier ... -
Risk factors for Aedes aegypti household pupal persistence in longitudinal entomological household surveys in urban and rural Kenya
(Springer Nature, 2020)Aedes aegypti is an efcient vector of several arboviruses of public health importance, including Zika and dengue. Currently vector management is the only available avenue for disease control. Development of efcient vector ... -
Species Composition, Phenotypic and Genotypic Resistance Levels in Major Malaria Vectors in Teso North and Teso South Subcounties in Busia County, Western Kenya
(Hindawi, 2020-01)Knockdown resistance (kdr) is strongly linked to pyrethroid insecticide resistance in Anopheles gambiae in Africa, which may have vital significance to the current increased use of pyrethroid-treated bed net programmes. ... -
Simultaneous detection of anthracene and phenanthrene on Ag-Au alloy nanoparticles/overoxidized-polypyrrole composite modified carbon electrode
(IOSR Journal of Applied Chemistry, 2019-02-22)A simple and highly selective amperometric sensor for simultaneous determination of anthracene (AN) and phenanthrene (PHE) has been developed based on a composite of overoxidized-polypyrrole (PPyox) and Ag-Au ... -
Application of Central Composite Design to Optimize Spawns Propagation
(Scientific Research Publishing, 2020)Despite the increased recognition of the nutritional value of the Oyster mushroom, coupled with its ability to tolerate a wide range of climatic conditions, its production is still at infancy stage with low adoption rate ... -
Optimization of Oyster Mushroom Yield By Using Simplex-Centroid Mixture Design
(Journal of Scientific Research and Innovative Technology, 2020)Despite the increased recognition of the nutritional value of the Oyster mushroom, coupled with its ability to tolerate a wide range of climatic conditions, its production is still at infancy stage with low adoption rate ... -
Dual-band graphene-induced plasmonic quarter-wave platemetasurface in the near infrared
(Springer Berlin Heidelberg, 2017)Weak graphene plasmon is a key challenge for graphene-based meta surfaces in the visible and near-in-frared regions. In this study, we have numerically designed and demonstrated a tunable, ultra thin, ... -

(Pergamon, 2014)Nanostructuredpoly(4-styrenesulphonicacid) and tantalum(IV)oxide-doped polyaniline nano composite were synthesized and their elector-conductive properties were determined.The oxide was synthesized using a modified sol gel ... -
Extreme Value Modelling of Rainfall Using Poisson-generalized Pareto Distribution: A Case Study Tanzania
(Science Publishing Group, 2019)Extreme rainfall events have caused significant damage to agriculture, ecology and infrastructure, disruption of human activities, injury and loss of life. They have also significant social, economical and environmental ... -
Analysis of Head Loss in Pipe System Components: Quasi-one-Dimensional Nozzle Flow
(2014)The problem under investigation is to determine the flow-field variables that is the total head which is the sum total of Elevation head, velocity head and pressure head instantaneous distributions as ... -
Characterization of antibiotic resistance in environmental enteric pathogens from Kibera slum in Nairobi-Kenya
(Academic Journals, 2012)Kibera slum is characterized by poor sanitation hence the frequent outbreaks of diarrheal diseases. Emergence of antibiotic resistance by diarrhoea-causing bacteria is an inevitable challenge in the area. Diarrhea-causing ... -
Biodegradability of polyethylene by bacteria and fungi from Dandora dumpsite Nairobi-Kenya
(Public Library of Science, 2018)This study aimed at isolating and identifying bacteria and fungi with the capacity to degrade low density polyethylene (LDPE). The level of biodegradation of LDPE sheets with bacterial and fungal inoculums from different ... -
Investigation on reversible pump turbine flow structures and associated pressure field characteristics under different guide vane openings
(Science China Press, 2019)The use of reversible pump turbines (RPT) within pumped storage power plants goes with prolonged periods of off-design operating conditions, which leads to the onset of operating mode-dependent instabilities. In order to ... -
Numerical Solution for a Model on Cancer Growth Reduction Using both Chemotherapy and Radiotherapy
(Research India Publications, 2019)Using mathematical models to simulate dynamic biological processes has a long history. In this study, we have employed mathematical modeling to understand the behavior of cancer and its interaction with both chemotherapy ... -
Refined node polynomials via long edge graphs
(2015)The generating functions of the Severi degrees for sufficiently ample line bundles on algebraic surfaces are multiplicative in the topological invariants of the surface and the line bundle. Recently new proofs of this fact ... -
