Occupational Health and Safety Administration (OSHA) in the Morgues: Management and practice of the universal precautions in Morgues in Kenya
(Biosafety, 2015)Morgues provide a risky work environment that requires universal safety precaution since it presents a variety of Occupational Health and Safety (OHS) challenges. Although OHS is a top priority internationally, in ... -
Occurrence and genotypic characterization of Diplostomum species (Digenea: 2 Diplostomidae) in Oreochromis niloticus L. and snail vectors in Kisumu 3 municipality 4
(Maseno University,Department of Zoology, 2005)Diplostomum species metacercariae, are trematodes that pose economic threat to aquaculture practice globally. Despite their diversity, species identification is difficult owing to their striking morphological similarities, ... -
Occurrence and lesions associated with Echinostoma revolutum in free-range chickens in Kenya
(University of Nairobi, Kenya, 2012)The study was carried out between November 2008 and April 2009 to investigate the occurrence and pathology due to Echinostomum revolutum in free-range indigenous chickens. One hundred and fifty six (156) indigenous ... -
Occurrence characteristics of equatorial plasma bubbles over Kisumu, Kenya during Solar maximum of Solar Cycle 24
(International Journal of Advanced Astronomy, 2021)Equatorial Plasma Bubbles (EPBs) are irregular plasma density depletions in the ambient electron density in the equatorial F-region ion osphere generated after sunset. EPBs are known to bring disruptions to telecommunication ... -
Occurrence of Trypanosoma in Nile tilapia in Lake Victoria, Kenya
(Sokoine university of agriculture, 2008)Oreochromis niloticus (Nile tilapia) and Lates niloticus (Nile perch) are the most abundant species and economically important fish in Lake Victoria. The former are omnivores and the latter are carnivorous. The carrier ... -
On a complex spacetime frame: new foundation for physics and mathematics
(Research gate, 2016)This paper provides a derivation of a unit vector specifying the temporal axis of four-dimensional space-time frame as an imaginary axis in the direction of light or general wave propagation. The basic elements of the ... -
On atomic state purity operator, degree of state purity and concurrence in the JC and anti-JC models
(arxiv.org, 2022)The state of an atom in a bipartite qubit, Jaynes-Cummings (JC) or anti-Jaynes-Cummings (aJC) interaction is described by a reduced density operator. The purity of the state has been measured by taking the trace of the ... -
On atomic state purity operator, degree of state purity and concurrence in the JC and anti-JC models
(Maseno University, 2020)The state of an atom in a bipartite qubit, Jaynes-Cummings (JC) or anti-Jaynes-Cummings (aJC) interaction is described by a reduced density operator. The purity of the state has been measured by taking the trace of the ... -
ON SINGULAR CAUCHY PROBLEM OF EULER-POISSON DARBOUX EQUATION
(2012)We solve the singular Cauchy problem of Euler-Poisson-Darboux equation. The Riemann function, a solution corresponding to the adjoint equation is calculated and it enables us to evaluate any solution at a point by the ... -
On the Solution of Confined Aquifer Flow Equations: Finite Difference Approximations
(Hikari Ltd, 2013)In general, groundwater flow in porous media on a microscopic level is three-dimensional. However, when considering regional flow problems ie groundwater flow on a macroscopic level, it is noted that because of the low ... -
On the Solution of n-Dimensional Regular Cauchy Problem of Euler-Poisson-Darboux Equation (EPD)
(2017)A general exact solution to the n-dimensional regular Cauchy prob- lem of Euler-Poisson-Darboux (EPD) equation has been studied. Firstly, the general exact solution for the one dimensional regular Cauchy prob- lem of ... -
On the steady MHD couette flow between two infinite parallel plates in an uniform transverse magnetic field
(2015)In this paper we consider laminar viscous incompressible fluid between two infinite parallel plates when the upper plate is moving with constant velocity Uo and the lower plate is held stationary under the influence of ... -
Optical properties and Raman studies of amorphous Se-Bi thin films
(The African Review of Physics, 2014)Flash evaporated amorphous Se Bi (x = 0, 1, 2, 3, and 4 at. %) thin films of 350 ± 10 thickness have been investigated in the wavelength range of 200nm − 3000nm. It is found that the effect of increasing bismuth ... -

Optimising fermentation time in black tea manufacture
(Elsevier, 1986)A comparative study using in-line theaflavins analysis (ILTF), theaflavins of made-tea analysis (TFMT) and tasters' evaluations, to optimise fermentation during tea manufacture, was carried out. All methods obeyed a quadratic ... -
Optimization of biodiesel synthesis from Jatropha curcas oil using kaolin derived zeolite Na–X as a catalyst
(Royal Society of Chemistry, 2022)Biodiesel is an alternative renewable green fuel obtainable from the reaction of plant or animal oil with a low molecular weight alcohol in the presence of a catalyst. However, the cost of its production remains high due ... -
Optimization of Bioethanol Production from Sweet Sorghum Stalk (Sorghum bicolor (l.) Moench) Juice Using Response Surface Method
(Science publishing group, 2022)The use of fossil fuel as a source of energy has been unsustainable and has adverse effects to the environment. Bioethanol is a suitable alternative due to its exceptional properties. Bioethanol production can be done ... -
Optimization of parameters for bio-ethanol production from sweet sorghum (Sorghum bicolor (L.) Moench) stalk juice and finger millet malt using Taguchi method
(2024)Bio-ethanol is a promising renewable energy but its production is expensive from high cost of feedstocks. In this study, sweet sorghum (Sorghum bicolor (L.) Moench) stalk juice was investigated for bio-ethanol production. ... -
