Query: Isentropic Equation of State of Two-Flavour QCD in a Quasi-Particle
  Model   We examine the isentropic QCD equation of state within a quasi-particle model
being adjusted to first principle QCD calculations of two quark flavours. In
particular, we compare with Taylor expansion coefficients of energy and entropy
densities and with the isentropic trajectories describing the hydrodynamical
expansion of a heavy-ion collision fireball.
