The results are presented for both proton-nucleus and nucleus-nucleus collisions. For the case of heavy flavour production at comparatively low energies, if $\\sigma \\sim A^{\\alpha}$, the values of $\\alpha$ are slightly higher than unity. With increasing energy $\\alpha$ decreases in all cases and becomes smaller than unity. We also show $\\alpha$ as a function of Feynman-$x$ of","authors_text":"C. A. Salgado, C. Pajares, N.
