    "abstract": "An analysis is performed of the liquid-gas phase transition of nuclear matter\nobtained from different versions of scalar derivate coupling suggested by\nZimanyi and Moszkowski (ZM) and the results are compared with those obtained\nfrom the Walecka model. We present the phase diagram for the models and one of\nthem, the ZM3 model, has the lowest critical temperature $T_c=13.6$ MeV with\nthe lowest critical density $\\rho_c=0.037$ f$m^{-3}$ and pressure $p_c=0.157$\nMeV f$m^{-3}$.\n  These results are in accord with recent observations from energetic heavy-ion\ncollisions, which suggest a small liquid-gas phase region.",
