Analysis of fatigue crack initiation and S–N response of model cast aluminium piston alloys
(2011)
Fatigue crack initiation and S–N fatigue behaviour of hipped model Al7Si–Sr and Al0.7Si piston alloys have been investigated after overaging at 260 °C for 100 h to provide a practical simulation of in-service conditions. ...
Trace elements in PM2.5 in Gothenburg, Sweden
(2010)
Ambient aerosol particles smaller than 2.5 µm (PM2.5) are getting more and more attention worldwide. While legal focus is mainly on sample mass, the composition of the particles is an important research field gaining ...
The Political Economy, Manipulation And Watershed Degradation In KENYA
(University of Nairobi,, 2010)
Kenya’s experience in terms of draught, erratic rainfall patterns, scarcity of water and
rationing of electricity exposes the powerful relationship between environmental issues
and the political system. These ...
Micromechanisms of fatigue crack growth in cast aluminium piston alloys
(2012)
The fatigue crack growth behaviour in as-cast and hot isostatically pressed (HIP) model cast aluminium piston alloys with hypoeutectic Si compositions of 6.9 wt% and 0.67 wt% has been investigated. The HIP alloys showed ...
Radioactivity in Surface Soils around the Proposed Sites for Titanium Mining Project in Kenya
(2011)
Radioactivity measurements were carried out around Maumba and Nguluku villages, two of the proposed sites for tita-nium mining in the coastal area of Kenya. Samples of surface soils were analyzed using a HPGe gamma ...
Component ratios of new building costs in Nairobi: a contractors' perspective
(2012)
Abstract
Purpose - The aim of this paper is to use the case study of Nairobi in Kenya in order to fill the gap of
knowledge on the component ratios of new building costs that has been missing from international
litera ...

Electrolytic Etching of Platinum- Aluminium Based Alloys
(2012)
The microstructures of as-cast and annealed platinum alloys of different compositions were revealed after electrolytic etching in hydrochloric acid/sodium chloride solution using direct current. It was shown that the etching ...
