... Configuration The dictionary accepts one obligatory parameter - RULES, which has to be set to the file describing parsing rules and output recipes. ... Each non-empty line is either a comment (when started with '#' symbol), or a conversion rule, and in the latter case has to contain whitespace-separated pattern and output recipe. Currently, pattern has to match the _integer_ (one, two or more) number of input tokens; they will be replaced with a single one. ...

This year's two most powerful active areas, which passed across the solar disk at the beginning of May, 2009, are set to appear in the Sun's eastern sector in two days, on June 6th. ...

... 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. ...
