Non-destructive analysis of Mercury(Hg) by Energy Dispersive X-ray Fluorescence (EDXRF) Technique in Beauty Creams sold in Kenya
(International Atomic Energy Agency (IAEA)Institute of Nuclear Science & Technology, University of Nairobi, 1996-11)Analysis of mercury(Hg) in 100 different beauty creams by energy dispersive x-ray fluorescence technique is described. Each sample was brought to a melt by warming on a water bath at 40-50°C, and then poured onto a 2.5 ... -
Non-destructive XRF analysis of Nigerian and Kenyan clays
(University of Nairobi, 1997-04)Nigerian and Kenyan clays were analysed using energy dispersive X-ray fluorescence (EDXRF) technique and thirteen elements (Ca, Ti, Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, Zr, Nb and Pb) were detected. The health implications, ... -
Non-invasive Intraoperative Imaging using Laser Radar System in Hip-joint Replacement Surgery
(2004)This paper explores the possibility of employing a non-invasive registration technique using a high resolution pulsed laser radar system as an intraopera tive imaging system in computer assisted hip-joint replacement ... -
A Non-invasive Registration Technique in Hip-joint Replacement Surgery Using Laser Radar Imaging
(2004)In this paper, we present a 3D imaging technique for computer-assisted hip-joint replacement surgery. It is based on a high resolution laser radar which uses powerful picosecond laser pulses, generated from low-cost ... -
Nonlinear mixed effect modelling for improved estimation of water retention and infiltration parameters
(2006)Accurate estimation of soil hydraulic functions is an important topic in soil physics and hydrology. Soil scientists and hydrologists use experimental data to derive parameters of the hydraulic functions, and when measurements ... -

The North-South Divide in urban patterns and the contradictions of using homogeneous instruments of planning:lessons from Kenya
(Africa Hbitat, 2020-02-20)Three development pathways characterize all urban societies in the world and, this, by necessity, result in different spatial patterns. The first pathway can be viewed as laissez faire, which produces informal or organic ... -
Note on the effect of cross-sensitivity in the determination
(University of Nairobi,, 1971)The concentric Mohr circles of modified apparent strain, true strain and stress permit quick visualisation and calculation of true strains and stresses from readings of gauges with known cross-sensitivities -

Numerical Modelliing Of Square Tubular Steel Beams Subjected To Transverse Blast Loads Thin
(Department of Civil Engineering, Monash University, Vic. 3800, AustraliaBlast Impact Survivability Research Unit (BISRU), Department of Mechanical Engineering, University of Cape Town, Private Bag,Rondebosch 7701, South AfricaNSW Injury and Risk Management Research Centre, UNSW, NSW, 2052 Sydney, Australia, 2009)This paper presents the numerical simulations of thin-walled square hollow steel beams subjected to a uniform transverse blast load. The objectives of the numerical simulations were to gain an insight into the temporal ... -
Numerical Modelling of Aerodynamic Performance of Aerofoil Windmill Blades at Various Blade Configurations
(1995)Abstract The accurate prediction of the aerodynamics and performance of vertical-axis wind turbines is essential if their design is to be improved but poses a significant challenge to numerical simulation tools. The ... -
Numerical Study Of County Solid Waste Management At The Dumpsite
(2015)This study presents the development of one dimensional mathematical model capab le of simulating simultaneous processes of oxygen flow. It is based on some assumptions like the dumpsite ... -

Occupational exposure to roadway emissions and inside informal settlements in sub-Saharan Africa: A pilot study in Nairobi, Kenya
(Univerisyt of Nairobi, 2015)Few studies examine urban air pollution in sub-Saharan Africa (SSA), yet urbanization rates there are among the highest in the world. In this study, we measured 8-hr average occupational exposure levels of fine particulate ... -
Occupational radiation exposures of artisans mining columbite–tantalite in the eastern Democratic Republic of Congo
(2007)Artisans in Masisi and other parts of the North Kivu province in the eastern Democratic Republic of Congo (DRC) mine columbite–tantalite mineral ores (also called 'coltan') for the tantalum content. The potential occupational ... -
Off-grid lighting products in Kenya
(2010)Less than 20% of Kenya's population is connected to the grid. Only 5% of the country's rural population, which accounts for over 70% of the total population enjoys electricity connectivity. To compensate for this deficiency ...
