\caption{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.}
