... One of the objectives of this work is to derive radial distribution of supernova remnant surface densities in spiral galaxies. ... Other objectives include the comparison of the SNR radial distribution with the radial distribution of HII regions to look for any association between Type II progenitors and the SNRs and comparison of the SNR distribution to the spiral arm patterns. ... Knowing the positions of the SNRs, we can compare their distributions relative to HII regions and spiral arms. ...

... 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. ...
