  The normal state behaviour of the density of states of the electrons
described by the BOSON - FERMION model for Bose-Einstein condensation driven
superconductivity is characterized by the appearence of a pseudogap which
developes into a true gap upon lowering the temperature and the superconducting
critical temperature is approached. The consequences of this on the temperature
dependence of the specific heat, the NMR relaxation rate and the optical
conductivity is examined.
