Using the recent F2 logarithmic slope data as a constraint to the adustable parameters, the inclusive structure function is described in a wide range of the small x HERA kinematical region, consistent with the unitarity bound. We also extrapolate the extimates to the THERA region.23 pages, 13 figures, uses jhep.clsHigh Energy Physics - Phenomenologytext
