Investigation of Temperature effects for a finite elasto-hydrodynamic journal bearing lubricated by Ferro fluids with couple stresses
(2015)The performance of finite elasto-hydrodynamic journal bearings lubricated by ferrofluids with couple stresses has been studied. We derive the energy equation that takes into account magneto elasto-hydrodynamics. The ... -
Modelling Influenza Dynamics with Drug Resistance Aspect
(2017)Despite improvement in medical and public health standards, influenza continues to plague humankind causing high morbidity,mortality and socio-economic cost. Efforts to effectively combat the spread of influenza can be put in ... -
Hydromagnetic Jeffery-Hamel Unsteady Flow of a Dissipative Non-Newtonian Fluid with Nonlinear Viscosity and Skin Friction
(Research India Publications, 2018)In this paper, the unsteady two-dimensional Jeffery-Hamel flow of an incompressible non-Newtonian fluid, with nonlinear viscosity and skin friction, flowing through a divergent conduit in the presence of a constant applied ... -
A study of two-phase Jeffery Hamel flow in a geothermal pipe
(IJAAMM, 2018)In this paper a two-phase convergent Jeffrey-Hamel flow in a geothermal pipe concentrated with silica particles and thermophoresis has been studied. The governing equations are equation of mass, momentum, heat transfer ... -
Stability Analysis Using Nonstandard Finite Difference Method and Model Simulation for Multi-Mutation and Drug Resistance with Immune-Suppression.
(2018)We introduced recently a model that takes into account mutation and drug resistance of tumor cells in a case of simple immune system and immune-suppression caused by the resistant cells. The present study is to apply the ... -
Modeling the within-host co-infection of influenza A virus and pneumococcus
(Elsevier, 2018)In this paper a nonlinear mathematical model for a within-host co-infection of influenza A virus and pneumococcus is investigated. Conditions that explain the relations amid RIP and its relationship to the global asymptotic ... -
Kinetic derivation of a Hamilton-Jacobi traffic flow model
(2012)Kinetic models for vehicular traffic are reviewed and considered from the point of view of deriving macroscopic equations. A derivation of the associated macroscopic traffic flow equations leads to different types of ... -
Vegetation dynamics and responses to climate anomalies in East Africa
(2018)Vegetation plays a key role in the global climate system via modification of the water and energy balance. Its coupling to climate is therefore important, particularly in the tropics where severe climate change impacts ... -
Hydrological responses to climate change in Mt. Elgon watersheds
(Elsevier, 2015)Study Region: The Upper catchments of the Nzoia River basin in western Kenya. Study Focus: The potential streamflow responses to climate change in the upper Nzoia River basin are studied. The Soil and Water Assessment ... -
Occupational Safety and Health Management Systems and Their Compliance among Petrol Stations in Kenya: A Case Study in Nakuru County
(2019-08-22)Companies have a legal and social responsibility to ensure the safety of its workers, all persons lawfully present at the workplace and the surrounding community. This requires laid down procedures and routing process which ... -
Reflections on the genre-based approach to the teaching of thesis writing
(2018)This paper discusses how the genre-based approach can be employed in the teaching thesis writing in the universities. An analysis of six theses drawn from public universities in Kenya revealed that generic features fulfil ... -
A genre Analysis of the Scholarly Electronic Mail: Implications for Pedagogy
(University of Isfahan, 2018)Scholarly mails apparently display stable conventional principles as an emerging genre. Thus, contributors should structure their electronic mails appropriately when writing for purposes of discussing professional topics. ... -
Benthic Macro-invertebrate Diversity and Biomass Distribution in Relation to Canopy Cover and Organic Matter in River Njoro, Kenya
(Egerton University, 2013)Field experiments to quantify benthic macroinvertebrate density, diversity and biomass and benthic organic matter (BOM) content in the River Njoro, Kenya, were conducted between January 2009 and April 2009 at four sites ... -
Small Hydro-power Plants in Kenya: A Re view of Status, Challenges and Future Prospect
(Materials and Energy Research Center (MERC) & Iranian Association of Chemical Engineers (IAChE), 2016)Small Hydro-power Plants (SHP) are important sources of electricity in many countries. However, little is known about SHP in Kenya. This paper reviews the status, challenges in implementation of SHP and prospects for future ... -

Effect of drift sampler exposure time and net mesh size on invertebrate drift density in the Njoro River, Kenya
(Taylor & Francis, 2018)Although invertebrate drift is an important ecological process in lotic ecosystems, very little is known about it in Kenyan rivers. The primary aim of this study was to investigate the effect of driftnet mesh size and ... -
Invertebrate drift densities in the Njoro and Kamweti Rivers in the Kenyan highlands that differ in the level of anthropogenic disturbances
(Taylor & Francis, 2018)Invertebrate drift is one of several fundamental ecological processes in streams. However, little is known about the dynamics of invertebrate drift in Kenyan streams. In this study, we assessed invertebrate drift in two ... -
Attitude of teachers and students towards the use of punishment in secondary schools in Kaloleni District of Coast province, Kenya
(2011)This study was carried out in 14 secondary schools in Kaloleni District. A descriptive approach was employed. Data were collected through the questionnaires designed for the teachers and students. The target population ... -
Effect of Sieve Mesh Size on the Estimation of Benthic Invertebrate Abundance and Composition in the Honi River, Kenya
(Nature Kenya/East African Natural History Society, 2014)Characterisation of benthic invertebrate communities, taxonomic abundance and composition provides information that is used during river bioassessment. However, the mesh size of the sieves used during processing of ... -
Does the exclusion of meiofauna affect the estimation of biotic indices using stream invertebrates?
(Taylor & Francis, 2016)Biomonitoring of rivers is usually undertaken using information based on macroinvertebrate assemblages. However, exclusion of meiofauna (i.e. invertebrates less than 0.5 mm in size) when sorting benthic invertebrates can ...
