      Bica, Eduardo Luiz Damiani; Maia, Marcio Antonio Geimba; Bonatto, Charles Jose; Dottori, Horacio Alberto; Pastoriza, Miriani Griselda (1994) [Artigo de periódico]
      The star formation history in the nucleus of late spiral galaxies is compared between a sample in a high galaxy density medium (HDS) and a control sample (CS) of isolated galaxies. We have observed 20 HDS and 18 CS galaxies ...
