The alpha proton x-ray spectrometer (APXS) on board the rover of the Mars Pathfinder mission measured the chemical composition of six soils and five rocks at the Ares Vallis landing site. The soil analyses show similarity to those determined by the Viking missions. The analyzed rocks were partially covered by dust but otherwise compositionally similar to each other. They are unexpectedly high i...

A review and discussion of analytical developments in the determination of DDTs and PCBs in sea environment are presented, including sample treatment, clean-up, identification and quantitative determination by gas-liquid chromatography. The fates of chlorinated hydrocarbons in the sea are discussed with regard to the pollutant-particle association with surfaces and their dynamics in a coastal m...

In this paper we cluster and analyse temporal user behaviour in online communities. We adapt a simple unsupervised clustering algorithm to an evolutionary setting where we cluster users into prototypical behavioural roles based on features derived from their ego-centric reply-graphs. We then analyse changes in the role membership of the users over time, the change in role composition of forums ...
