We study the use of red sequence selected galaxy spectroscopy for unbiased estimation of galaxy cluster masses. We use the publicly available galaxy catalog produced using the semi-analytic model of De Lucia & Blaizot (2007) on the Millenium Simulation (Springel et al. 2005). We make mock observations to mimic the selection of the galaxy sample, the interloper rejection and the dispersion measu...

Precipitation hardened Copper-Chromium-Zirconium (CuCrZr) alloy is a prime candidate for divertor components in future European DEMOnstration (DEMO) fusion reactors. To develop the DEMO Design Criteria In-vessel Components (DDC-IC), failure criterion of CuCrZr needs to be investigated. Hence, effects stress triaxiality and loading strain rate on fracture solution heat treated annealed alloys we...
