    "abstract": "A self-consistent description of the MIT bag parameters as functions of the\nnuclear matter density is presented. The subnuclear degrees of freedom are\ntreated in the Quark-Meson Coupling Model, considering the equilibrium\nconditions for the bag in the nuclear medium. The hadronic interaction is\ndescribed in the framework of the quantum field theory of hadrons through\nseveral models. We have obtained the behavior of the bag radius and the bag\nparameters $B$ and $z_0$, taking their derivatives with respect to the mean\nfield value of the scalar meson as free parameters. A discussion on the\nvariation range of these derivatives is given.",
