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 ... -
A critical review of the effect of water storage reservoirs on organic matter decomposition in rivers
(NRC Research Press, 2016)Organic matter decomposition is vital in sustaining river food webs. However, little is known about the effect of water storage reservoirs on organic matter decomposition in rivers. In this paper, we reviewed and analyzed ... -
Methane-Derived Carbon in the Benthic Food Web in Stream Impoundments
(Public Library of Science, 2014)Methane gas (CH4) has been identified as an important alternative source of carbon and energy in some freshwater food webs. CH4 is oxidized by methane oxidizing bacteria (MOB), and subsequently utilized by chironomid ... -
Monitoring water and habitat quality in six rivers draining the Mt. Kenya and Aberdare Catchments using Macroinvertebrates and Qualitative Habitat Scoring
(2014)The study was conducted in June and September 2011 in six rivers that drain Mt. Kenya and the Aberdare catchments, i.e. Honi, Naro Moru, Liki, Sirimon, Mariara and Karigu. The main objective was to determine the ecological ... -
Effect of Small Impoundments on Leaf Litter Decomposition in Streams
(John Wiley & Sons, Ltd, 2015)Leaf litter decomposition is an important process providing energy to freshwater biota. Flow regulation and dams can strongly alter freshwater ecosystems, but little is known about the effect of small impoundments on leaf ... -
Landslide scar/soil erodibility mapping using Landsat TM/ETMþ bands 7 and 3 Normalised Difference Index: A case study of central region of Kenya
(Pergamon, 2015)Landsat series multispectral remote sensing imagery has gained increasing attention in providing solutions to environmental problems such as land degradation which exacerbate soil erosion and landslide disasters in the ... -
The relationship between Dividend Payout ratio and Capital Structure of companies quoted at the Nairobi Securities Exchange, Kenya in the industrial and allied sector
(International Journal of Economics, 2015)The existing literature on optimal dividend policy and capital structure is voluminous and has continuously evolved over the last five decades. The objective of this study was to establish the relationship between the ... -
Strategic planning and implementation practices at the Kisii county government in Kenya
(2013)The aim of this study was to ascertain strategic planning and implementation practices at the Kisii county government in Kenya. The researcher collected qualitative data from the County secretary, Deputy Speaker, County ... -
Estimation of Risk in Rwanda Exchange Rate
(2014)Generalized Autoregressive Conditional Heteroskedasticity (GARCH) approach was applied to Rwanda Exchange rate returns to estimating current volatility. We fitted autoregressive (AR) model with GARCH errors to the daily ... -
Estimation of Critical Streamflow Discharge Level Using Nonparametric Quantile Regression Model
(2016)Various parametric models have been designed to analyze volatility in river flow time series data. For maximum likelihood estimation these parametric methods assumes a known conditional distribution. This paper considers ... -
Limit Theory of Model Order Change-Point Estimator for GARCH Mode
(Scientific Research Publishing, 2018)The limit theory of a change-point process which is based on the Manhattan distance of the sample autocorrelation function with applications to GARCH processes is examined. The general theory of the sample autocovariance ... -
Application of Nonparametric Methods in Studying Energy Consumption
(University of Rwanda, 2011)Consumer behaviour towards different forms of energy varies over time. The variance can be so large that the quality of the estimation functional relationship between the response variable and its associated explanatory ...
