Title: Dependence of Nuclear Binding on Hadronic Mass Variation

Abstract:
We have studied how the binding of light (A<=8) nuclei
depends on possible variations of hadronic masses, including meson,
nucleon, and nucleon-resonance masses.  Small variations may have 
occurred over time, possibly affecting big bang nucleosynthesis.
Larger variations are relevant to current attempts to extrapolate
properties of NN interactions from lattice QCD calculations.
