We report on high spectral resolution observations of five damped Lyman-α absorbers: zabs = 3.0248 toward Q 0347–383, zabs = 2.1411 and 2.8112 toward Q 0528–250, zabs = 2.6184 toward Q 0913+072, and zabs = 2.5226 toward Q 1213+093. Line velocity profiles and heavy element abundances are discussed. Nitrogen is found to have abundances less than silicon in the systems toward Q 0347−383, Q 0913+07...

OBJECTIVE  To measure incidence of early death after discharge from emergency departments, and explore potential sources of variation in risk by measurable aspects of hospitals and patients. DESIGN  Retrospective cohort study. SETTING  Claims data from the US Medicare program, covering visits to an emergency department, 2007-12. PARTICIPANTS  Nationally representative 20% sample of Medica...
