Query: Penguin contributions to rates and CP asymmetries in non-leptonic
  B-decays. Possible experimental procedures and estimates   We present a study of non-leptonic B-meson decays, partial widths and CP
asymmetries, and discuss the possibilities of determining the penguin
contributions through less model-dependent phenomenological analyses. In the
last section we employ a specific model to give more definite numerical
predictions.
