The chiral limit of finite-volume &CD is the e-regime of the theory. We discuss how this regime can be used for determining low-energy observables of QCD by means of comparisons between lattice simulations and quenched and unquenched chiral perturbation theory. The quenched theory suffers in the e-r

Renormalization constants of vector (2,) and axial-vector (ZA) currents are determined non-perturbatively in quenched QCD for an RG-improved gauge action and a tadpole-improved clover quark action using the Schr6dinger functional method. Meson decay constants f, and fT show much better scaling when
