Abstract
We present our best estimates of the uncertainties due to heavy particle threshold corrections on the unification scale , intermediate scale , and coupling constant in the minimal nonsupersymmetric SO(10) models. Using recent data from the CERN collider LEP on and to obtain the two-loop-level predictions for and , we update the predictions for the proton lifetime in minimal nonsupersymmetric SO(10) models.
