heal.abstract	Presently there is preliminary observational evidence that the cosmologicalconstant might be non zero, and hence that our Universe is eternallyaccelerating (de Sitter). This poses fundamental problems for string theory,since a scattering matrix is not well defined in such Universes. In a previouspaper we have presented a model, based on (non-equilibrium) non-criticalstrings, which is characterized by	en
