is indeed due to an energy dependent (decreasing) survival probability a similar behavior would be expected for comparable photoproduction data involving resolved photons, but such a decrease would not be seen in deep inelastic scattering.

In Sec.5, we review BFKL searches performed at H1, ZEUS and DØ\[9,11-13\]. Each analysis, using two-jet inclusive measurements at Fermilab and a forward jet measurement at HERA, finds some evidence for BFKL behavior through an energy dependence which seems stronger than expected from leading and next-to-leading order perturbation theory. However, definitive results have not yet been achieved.

In Sec.6, progress in calculating the next-to-leading corrections in BFKL evolution is reviewed\[14\]. We may be near a rather complete understanding of these corrections. A preliminary estimate suggests a substantial reduction of the BFKL pomeron intercept.

Sec.7 is devoted to a brief discussion of some topics involving nuclear reactions. Parametrizations of diffraction dissociation at HERA have been successfully used to describe nuclear shadowing in fixed target deep inelastic lepton-nucleus scattering\[15\]. $J/\psi$ production in proton-nucleus and nucleus-nucleus scattering continues to be an important subject for research. New phenomenological success in describing all data except for Pb-Pb collisions by a simple absorption model\[16,17\], along with the suggestion that the Pb-Pb
