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 ...
A Model Hardness for Heat-Affected Zone Profiles in AI-Li-X Alloys
(1998)
A model based on reaction
kinetics and elemental diffusion is proposed
to account for the presence of
double inflection in the hardness profiles
of the heat-affected zone (HAZ) in weldments
of AI-Li-X alloys tested ...
Ecology of increasing disease, population growth, and environmental degradation.
(1998)
The World Health Organization (WHO) and other organizations report that the prevalence of human diseases during the past decade is rapidly increasing. Population growth and the pollution of water, air, and soil are ...
Temporal hydrologic response of unstable crusting soils in Semi- arid areas of Kenya
(1998)
Over the past three decades, agricultural watersheds in semi-arid Kenya
have experienced some rapid decline in soil and crop productivity due to severe soil
erosion, low soil water, low soil fertility and high soil ...
A Model for HAZ Hardness Profiles in AI-Li-X Alloys: Application to the AI-Li-Cu Alloy 2095
(1998)
In a previous paper (Ref. 1),
details were presented of a theoretical
model describing the evolution of the
hardness profiles in the heat-affected
zones (HAZ) of AI-Li-X weldments. The
intent of the model was to ...
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 ...
