We present an abundance analysis of light elements in the most massive chemically peculiar (CP) stars, He-rich stars. The analysis is based on both low and high-resolution observations collected at ESO, La Silla, Chile in the optical region and includes 6 standard and 21 He-rich stars. Light element abundances display a diverse pattern from under-solar up to above-solar values. Carbon is found ...

He humanized rather than conquered his disease. A mature humanism replac...

While his incredibly inventive mind enriched many fields, Claude Shannon's enduring fame will surely rest on his 1948 work " A mathematical theory of communication " [7] and the ongoing revolution in information technology it engendered. Shannon, born April 30, 1916, in Petoskey, Michi-gan, obtained bachelor's degrees in both mathematics and electrical engineering at the University of Michigan ...
