Table 1: Comparison of the wind ejecta of a 60 $M_\odot $ and a 7 $M_\odot $ model with Z=10-5 for different values of  $\Omega _{{\rm c}}$. $\Delta Y$ and $\Delta Z$ are the amounts of new helium and heavy elements ejected. The brackets indicate the ratios in log scale of the abundances in the winds or in the AGB envelopes compared to the solar ratios.
