heal.abstract	We examine, in the context of certain string compactifications resulting infive dimensional brane worlds the mechanisms of (self) tuning of thecosmological constant and the recovery of standard cosmological evolution. Weshow that self tuning can occur only as long as supersymmetry is unbroken(unless additional assumptions are made) and that the adjustment of thecosmological constant to zero	en
