Eu3 + as a luminescent probe for the local structure of trivalent dopant ions in barium zirconate-based proton conductors
(University of Nairobi, 2013-10)The luminescence spectra and decay kinetics of dry and hydrated samples of BaZr0.9Y0.099Eu0.001O2.95 have been measured at room temperature. The spectra of the dry sample evidence two 5D0 → 7F0 bands clearly indicating ... -
Turbulence structure in triangular subchannels of a reactor bundle model
(University of Nairobi, 1991)Presented is a study of turbulence structure in two triangular subchannels of a reactor bundle at both design condition and a case when one of the outermost rods is in contact with the wall. Measured parameters include rms ... -
Flow measurements in rod bundle subchannels with varying rod-wall proximity
(University of Nairobi, 1991-11)Detailed measurements of fully developed, turbulent, air flow through a five-rod sector of a 37-rod bundle have been conducted for the design geometry of the bundle, as well as for several cases with the central rod displaced ... -

Effect of coagulants and extent of colour removal from textile effluents
(1994)The conclusions to study the effectiveness of coagulants were arrived at following a general survey conducted to evaluate the commonly used coagulants during after treatment procedures in textile industries. The survey ... -
Workplace monitoring and occupational health studies in Kenya using nuclear and related analytical techniques
(Institute Of Nuclear Science, University Of Nairobi, Kenya, 1997)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 ... -
Analysis of soil for trace elements along two highways of Kenya
(1998)For a long time, the toxicity of metals was considered as an occupational hazard. Industrialization, urbanization, increased vehicular traffic and use of fertilizers and pesticides in agriculture have resulted in increased ... -
The atmosphere, aerosols, trace gases and biogeochemical change in southern Africa : a regional integration : START Regional Syntheses
(2001)Attention is focused on temperature and rainfall changes occurring over the subcontinent of southern Africa, on atmospheric circulation and transport of aerosols and trace gases in the vertical and horizontal, and on ... -
Sensitivity of off-nadir zenith angles to correlation between visible and near-infrared reflectance for use in remote sensing of aerosol over land
(2002)Cloud absorption radiometer (CAR) multispectral and multiangular data, collected during the Smoke, Clouds, and Radiation-Brazil (SCAR-B) Experiment, was used to examine the ratio technique, the official method for remote ... -
Measurement of 222Rn concentration in Kenyan groundwater.
(1998)Groundwater samples from different parts of Kenya have been analyzed for their 222Rn concentrations. Samples were drawn from municipal supplies, springs, wells and bore holes in different geological terrains. In the analysis, ... -
Nitrogen oxides, ozone and heavy metals analysis of suspended particulate matter (spm) of air in Nairobi, Kenya
(2001)Motor vehicle emissions are a major source of air pollution in most urban centers. In Kenya, Nairobi city has the highest traffic density and is therefore a particular cause for concern due to the poor maintenance standards ...
