A. Singh Institute of Mathematical Sciences, C.I.T. Chennai, India anupamk18@gmail.com Real elements in algebraic groups Let G be an algebraic group defined over a field k . ... Let G be a connected semisimple algebraic group of adjoint type defined over a perfect field k . ... It follows that if G is connected semisimple of adjoint type, with -1 in its Weyl group, then every semisimple element in G(k ) is strongly real in G(k ). This also shows that any regular element in such a group is real. ...

... We describe enhancements made to Sherpa for the CIAO 2.0 release, concentrating upon those that enable a user to: (1) analyze Chandra X-ray Observatory grating data with wavelength- or energy-space models; (2) simultaneously fit background and source datasets; and (3) estimate and visualize confidence intervals and regions. ... Sherpa is the modeling and fitting tool of the Chandra Interactive Analysis of Observations (CIAO) software package (Doe et al. 1998 and references therein). ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...
