The nucleus as a fluid of skyrmions: Energy levels and nucleon   properties in the medium
  A model of a fluid of skyrmions coupled to a scalar and to the $\o $ meson mean fields is developed. The central and spin-orbit potentials of a skyrmion generated by the fields predict correct energy levels in selected closed shell nuclei. The effect of the meson fields on the properties of skyrmions in nuclei is investigated.
