The model allows to extrapolate lattice QCD data to large baryo-chemical potential. We outline the thermal evolution of matter in the early universe at and slightly after confinement and comment briefly on charm dynamics in relativistic heavy-ion collisions.invited talk at Strangeness in Qaurk Matter 2004, Cape Town, Sep. 15 - 20, 2004High Energy Physics - Phenomenologytext
