Trace element analysis of mineral and tap water samples using total reflection x-ray fluorescence (TXRF)
(2000)Results of trace element analysis by TXRF of tap water and various brands of bottled mineral water samples which are representative of local and imported brands sold in Nairobi are reported. The variation in elemental ... -
Monitoring of suspended particulate matter (SPM), heavy metals and other parameters in some workplaces
(2000)This report presents results of measurements of sound levels, chemical analysis of air particulate matter and soil samples from two factories in Nairobi. A preliminary assessment of suspended particulate matter (SPM) in a ... -
Heavy metal analysis of suspended particulate matter (SPM) and other samples from some workplaces in Kenya
(1998)Air pollution studies in Nairobi are indicating a rising trend in the particulate matter loading. The trend is mainly attributed to increased volume of motor vehicles, the physical change of the environment, agricultural ... -
The determination of levels of mercury, cadmium and lead in water samples from Naivasha area, Kenya
(1995)The analysis of mercury, cadmium and lead in water samples from different environments (Lake Naivasha, River Malewa boreholes and Olkaria geothermal wells) in Naivasha region and their possible origins are reported. The ... -
Prospects of Establishing Food Irradiation Facilities in Kenya
(1997)A national project of food irradiation in the country is being proposed. At present there are no facilities for food irradiation (and food irradiation research) in Kenya. This report is therefore largely comparative ... -
Assessment of Ozone, Nitrogen Oxides, Air Particulate Matter in the Ambient Air of Nairobi city
(2006)World wide, more than 1.1 billion people live in urban centres that are highly polluted by industrial and other human activities. Among the most common and most virulent air pollutants are sulphur dioxide,suspended particulate ... -
Air pollution in Kenya
(1993)Energy Dispersive X-ray Fluorescence (EXDRF) analysis of aerosol samples in Nairobi is presented. Results show that elemental concentrations is of the order of 10^ to lO"10 \igfm^ for most elements analyzed. The total ... -
EDXRF analysis of local and imported pica soil samples
(EAST AFRICAN JOURNAL OF SCIENCE I Volume 3 -Part 1 June 2001, 2001)Several studies have implicated trace metal metabolism with some human diseases. Energy Dispersive X-Ray Fluorescence(EDXRF)method was used to analyse pica soil samples, which are consumed by some pregnant mothers in ... -
A simple diffusion model for calculating concentrations from line sources in Nairobi
(1994)A simple physically realistic model is used for estimating carbon monoxide(CO) from highway in Nairobi using motor vehicle data for 1989. The year 1989 was chosen because it was the most recent year with motor vehicle count ... -
Pixe analysis of trace elements in tissues of rats treated with anticonvulsants
(1987)Several lines of evidence implicate metals in epilepsy. Anticonvulsant drugs are noted to alter levels of metals in humans and animals. PIXE analysis was used to investigate effects of three anticonvulsant drugs on tissue ... -
Lead and other metals distribution in local cooking salt from the fofi salt‐ spring in akwana, middle benue trough, Nigeria
(1991)Energy Dispersive X‐ray Fluorescence(EDXRF) technique has been used to determine the concentrations of lead(Pb) and other heavy metals in local cooking salts(LCS) from Akwana village, Middle Benue Trough, Nigeria. The ... -
The impact of pollution on the ecology of the Nairobi-Athi River system in Kenya
(1991)The pollution of the Nairobi-Athi River System is assessed by heavy metal analysis of the river water, industrial effluents, the invertebrate community and the riverine vegetation between Nongara upstream (UP) and 14 falls. ... -
ICT Infrastructure Sharing Framework for Developing Countries: Case of Mobile Operators in Kenya
(University of Nairobi, 2015)The lack of infrastructure in Africa especially south of the Sahara is widely recognized as one of the continent’s greatest impediments to sustainable development )[(1)]. Even with this challenge, ICT operators in Kenya ... -
Potential of digital geoinfotechs in planning urban community settlements: the case study of Mlolongo settlement, Nairobi –Kenya
(University of Nairobi, 2015-04)This research paper attempts to explore the potential of modern digital Geoinformation technologies (GITs) as alternative tools for spatial mapping, planning and management is compared against ... -

Evaluation of Kenyan bentonite clay as geothermal well drilling mud
(University of Nairobi, 2015-03)The quest for the development of geothermal plants with capacities up to 10,000 MWe in Kenya has recen tly placed greater demand on bentonite clay. Bentonite clay is at present largely imported into the ... -
Stochastic Methods for Aircraft Design
(1998)The global stochastic optimization method, simulated annealing (SA), was adapted and applied to various problems in aircraft design. The research was aimed at overcoming the problem of finding an optimal design in a space ...
