  We calculate the yields of pions, kaons, and $\phi$-mesons for RHIC and LHC
energies assuming thermodynamical equilibration of the produced minijets, and
using as input results from pQCD for the energy densities at midrapidity. In
the calculation of the production of partons and of transverse energy one has
to account for nuclear shadowing. By using two parametrizations for the gluon
shadowing one derives energy densities differing strongly in magnitude. In this
publication we link those perturbatively calculated energy densities of partons
via entropy conservation in an ideal fluid to the hadron multiplicities at
chemical freeze-out.
