Ancient volcanic xenon in single glass grains from the D'Orbigny angrite
We present high-sensitivity xenon data for single glass grains from the D'Orbigny angrite. These grains contain the first sample of volcanic gas from a planetary body other than the Earth and excess Xe-129 detected for the first time in angrites
A systematic search for massive young stars in the Galaxy - the RMS survey
We have selected red MSX sources (RMS) that have the colours of massive young
stellar objects (MYSOs). Our aim is to generate a large, systematically
selected sample to address questions such as their luminosity function,
lifetimes, clustering and triggering. Other objects such as UCHIIs, PN, PPN and
AGB stars have similar IR colours and a large programme of ground-based
follow-up observations is underway to identify and eliminate these from the
sample of the red MSX sources. These include radio continuum observations,
kinematic distances, ground-based mid-IR imaging, near-IR imaging and
spectroscopy to distinguish. We report the progress of these campaigns on the
3000 candidates, with initial indications showing that a substantial fraction
are indeed massive YSOs.Comment: 3 pages, 4 figures Talk in conference: Milky Way surveys, the

Service life prediction under combined cyclic and steady state tearing
© 2017 Taylor & Francis Group, London, UK. In this paper a novel approach for modelling failure under a combination of cyclic and static loading is presented. The cyclic fatigue and steady state tearing performance of two non-strain crystallising elastomers, NBR and EPDM, are initially characterised. A simplified component was then tested to failure using a combined cyclic/steady-state loading regime and its service life is compared against predictions from the developed analytical model
