Degradation characteristics of metribuzin in soils within the Nzoia River Drainage Basin, Kenya
(Taylor & Francis, 2016)Metribuzin, a triazinone herbicide, is heavily used within the expansive Nzoia River Drainage Basin in Kenya for the optimization of sugarcane yields. For field experiments, soils were spiked with metribuzin and amended ... -
Demonstration of Raman-based, dispersion-managed VCSEL technology for fibre-to-the-hut application
(Elsevier, 2017-03)For the first time, we experimentally investigate the use of vertical cavity surface emitting lasers (VCSELs) in the fibre-to-the-home (FTTH) flavour for Africa, known as fibre-to-the-hut. Fibre-to-the-hut is a VCSEL ... -
Determinants of Mobile Money Remittance in East Africa
(2017)Globally, remittances represent an important flow of international financial resources. In the East African trading bloc, the dynamic population movements between countries has led to widespread distribution of population ... -
Determination of Anthracene on Ag-Au Alloy Nanoparticles/Overoxidized-Polypyrrole Composite Modified Glassy Carbon Electrodes
(Molecular Diversity Preservation International, 2010)A novel electrochemical sensor for the detection of anthracene was prepared by modifying a glassy carbon electrode (GCE) with over-oxidized polypyrrole (PPyox) and Ag-Au (1:3) bimetallic nanoparticles (Ag-AuNPs). The ... -
Determination of serum isometamidium levels in sheep and goats under field conditions using isometamidium-ELISA
(2000)Twenty eight sheep and 28 goats were treated with isometamidium chloride (Samorin®, hone Merieux, Lyon, France) at a dose of 1 mg/kg body weight (bw) by intramuscular injection. All the animals were grazed in a tsetse-infested ... -
Discussion on Generalized Modified Inverse Rayleigh
(2018-01-01)In this paper, a generalization of the modified inverse Rayleigh distribution called the new exponentiated generalized modified inverse Rayleigh distribution is proposed and studied. Various sub-models of the new distribution ... -
Dissipation Behavior of Malathion and DimethoateResidues from the Soil and Their Uptake by Garden Pea(Pisum sativum)
(Environmemental Contamination and Toxicology, 2000)The contamination of soil by pesticide chemicals can occur through direct application to control some inhabiting insect pests of a variety of economic plants while indirect avenues can occur through aerial ... -
The dissipation and degradation of methoxy‐ 14C malathion in soil under tropical conditions
(Taylor & Francis Group, 2000)l4C-malathion[S-1,2-bis(ethoxycarbonyl) ethyl O,O-dimethyl phosphorodithioate] has been studied in soil under tropical field conditions by applying the 14C-malathion pesticide to soil in Polyvinyl chloride (PVC) pipes ... -
The dissipation of malathion and dimethoate from the pea plants (Pisum sativum) under controlled conditions
(Taylor and Francis, 2000)4C-malathion, [S-1,2-bis(ethoxycarbonyl)ethyl O,O-dimethyl phosphorodithioate] and 14C-dimethoate, [O,O-dimethyl S-(N-methylcarbamoylmethyl)phosphorodithioate] have been admin-istered to leaves of pea (Pisum ... -
Distributive and Quantile Treatment Effects: Imputation Based Estimators Approach
(Journal of Statistical and Econometric Methods, 2018)This paper develops two new classes of estimators measuring the distributive effects of a treatment on a population. Using imputation methods, empirical quantile and bootstrap simulations, we managed to define and study ... -
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, ... -
Ecology and Management of Lake Naivasha, Kenya, in Relation to Climatic Change, Alien Species' Introductions, and Agricultural Development
(University Of Nairobi, 1990)Lake Naivasha is an important freshwater resource for Kenya's foreign-currency-earning agriculture and tourism, and for water-supply. It has always experienced extensive water-level fluctuations as a consequence of irregular ... -
The efect of various fuels on the yield, structural and optical properties zinc zirconate nanocomposite
(Springer Berlin Heidelberg, 2020)Various types of fuels were used in a low-temperature solution combustion synthesis of zinc zirconate nanocomposite at a pH of 7. In the synthesis, the fuels used were citric acid, glycine, urea, hydrazine hydrate, and ... -
Effect of Occupation on the Levels of Lead in Human Blood in Kenya
(Chemistry and Materials Research, 2013)The occupation an individual is involved in exposes him or her to different levels of lead from the work environment. The main occupation of the study subjects included working in the petrol stations, ... -
Effects of carbon amendment on in situ atrazine degradation and total microbial biomass
(ARPN Journal of Agricultural and Biological Science, 2013)This study elucidates the effects of carbon amendment on metabolic degradation of atrazine (6-chloro-N2-ethyl-N4-isopropyl-1,3,5triazine-2,4-diamine) and total microbial biomass in soil. Degradation of 14C-ring-labelled ... -
Effects of Magnetic Induction on MHD Boundary LayerFlow of Dusty Fluid over a Stretching Sheet
(2018)This paper investigates effects of induced magnetic field on the MHD laminar boundary dusty fluid flow over a stretching flat plate surface. The dusty fluid flow is influenced by an external uniform magnetic ... -
