Electro Catalytic Decompsition Of Captan And Methoxychlor Pesticide Residues Using Cyanocobalamin
(University of Nairobi,, 2014)The current study involved electrocatalytic reduction of the organochlorine pesticide residues which are, (3aR,7aS)-2-[(trichloromethyl)sulfanyl]-3a,4,7,7a-tetrahydro-lHisoindole- l,3(2H)-dione (Captan) and 1,1, ... -
Electrocatalysis of ascorbic acid oxidation on a polyaniline derivatized electrode
(Depatment of Chemistry, University of Nairobi, 1993)The results presented in this thesis reveal marked improvement in the oxidation characteristics of ascorbic acid, when the latter 1.s oxidized on a polyaniline derivatized carbon graphite working electrode. The pH of the ... -
Electrocatalytic Decomposition of Tetrachlorvinphos in Acetonitrile-water Media Using Cyanocobalamin
(University of Nairobi, 2018)This study investigated the electrocatalytic degradation of tetrachlorvinphos pesticide standard in acetonitrile-water media using cyanocobalamin catalyst. It was initiated by reports recorded from various consumers who ... -
Electrocatalytic reduction of toxic organohalides in surfactant microstructures
(University of NairobiDepartment of Chemistry, 1994)In a bicontinuous conductive media of 23 :34:43 didodecyldimethylammonium bromide DDAB/n-dodecane/water microemulsion (% by wt.), controlled potential electrolysis was performed at the two diffusion controlled reduction ... -

Electrochemical features of polytidophene on clay modified electrodes
(Depatment of Chemistry, University of Nairobi, 2002)In this thesis, electrochemical analysis of the conducting polymer polythiophene was performed using cyclic voltammetric technique. Carbon graphite was used as the working electrode in the various studies. Potential ... -
The electrochemical study of the factors affecting underground corrosion
(1979)An electrochemical study of some of the factors affecting the corrosion of steel in soils has been carried out. The factors studied were oxygen diffusion rates, soil moisture content, soil resistivity, salt concentrations, ... -
Electrodeposition characteristics of polyaniline conductive polymer
(Depatment of Chemistry, University of Nairobi, 1994)Polyaniline has been shown to be electrosynthesised at very low Sulphuric acid concentration ie. up to 0.5M H2S04. Anodic peak current variation with time has been shown to vary quite haphazardly for various solution pH. ... -
Electrohydrodynamic Atomization of Non-newtonian Liquids With High Solid Content- a Case Study for the Production of Powder.
(University of Nairobi, 2020)Electrohydrodynamic atomization (EHDA) is now a well-known technique among the researchers as a potential technique for industries. The technique uses electric fields to produce mono-dispersed charged droplets and ensures ... -
An Electronic Government Integrated System Using Service Oriented Architecture
(University of NairobiSchool of Computing and Informatics, 2013)The aim of the study was to investigate the application of Service Oriented Architecture (SOA) as an integration solution to disparate departmental government information systems with the aim of improving service delivery. ... -
Electronic Land Registry for Kenya
(School of Computing and Informatics, 2010)Land in most Kenyan societies is the most important of the natural resources, representing the foundation of much of the country's economic activity. For most individual Kenyans, the purchase of a parcel of land represents ... -
Elephants and their interactions with people in the Tana river region of Kenya
(University of NairobiCollege of Biological and Physical Sciences, 1979-05)This dissertation describes and evaluates interactions between elephants and people in the 40,000 km2, semi-arid lower Tana River region of eastern Kenya. Traditional forms of land use pastoralism and flood plain ... -
Elliptic Curves and Elliptic Curve Cryptography
(2009)Koblitz [7, 1987] and independently Miller [10, 1986] suggested the use of the group of points of an elliptic curve de ned over a nite eld Fq. The main incentive for this suggestion was based on the fact that the ... -
Elution And Partial Characterisation Of Immunoglobulins Bound To Goat Placenta
(University of NairobiSchool of Biological Sciences, 2000)The success of viviparous pregnancy in the vertebrate species remains a major puzzle to immunologists. Thus, the fetus is antigenic ally foreign by virtue of its paternally derived genes yet if is not rejected. The ... -
Elution purification and partial characterization of immunoglobulin-G bound to normal and pathological human placentae
(2005)The unexpected failure of the mother to immunologically reject the foetus is partly thought to result from immunological properties of the placentae and other regulatory factors, which include immunoglobulin G (IgG). ... -
EM Algorithm for Poisson-Lindley Distribution
(University of Nairobi, 2021)Mixed Poisson distributions have been used in scientific fields for modelling non-homogenous populations, (Karlis and xekalaki, 2005).. For example, in acturial applications, mixed Poisson distributions are used for ... -
An embedded framework for integrating speed, alcohol and weight monitoring in a public service vehicle
(University of Nairobi, 2014-06)Road Carnage is a great problem in our Kenyan roads. To reduce this, the government have tried to introduce regulatory laws for drivers on the roads. For instance, all public service vehicles except taxi cabs and commercial ...
