Period Changes as Evidence for Evolution in , Cend the title carefully. It does not promise that there really is evidence for evolution in Omega Centauri. It only proposes to look at the period changes with evolution in mind. We may all decide that the evidence is strong or that it is weak or perhaps that there is no evidence at all.

An Abundance Analysis of Fehrenbach’s Star (HD 116745) in Omega Centauri=1.0±0.3 and M =0.37 M.±.. Results of the curve-of-growth analysis, in which a model atmosphere was used to determine the curve appropriate to the star, yield a logarithmic iron-to-hydrogen abundance ratio with respect to the Sun of [Fe/H] = ?1.2 with a provisional estimated uncertainty of about ± 0

Variable Stars in Dwarf Spheroidal Galaxiesnce reliable magnitude sequences have been set up, the variable stars found, and their periods determined. Six dwarf spheroidal galaxies are presently known in the Local Group within a distance of 250 kpc. In Table I, which lists members of the Local Group, they are at the low-luminosity end of the

Sidney Van Den BerghRUCK in der ?K?lner Zeitschrift für Soziologie und Sozialpsychologie“, 1961, S.1–40). Mit diesem Ansatz, der eine Individualit?t vor einer sozialen Existenz unterstellt, ist der Zugang zum Rollenbegriff versperrt. Dieser Zugang soll hier erleichtert werden, indem zun?chst auf die Entwicklung des Rol

Diese Tatbest?nde sind u. a. zwischen Haushalten und Unternehmungen anzutreffen. Es dreht sich z. B. in dieser Hinsicht um die Erkl?rung der durch eine bestimmte Familie nachgefragt
