Abstract
We show that for any countable discrete maximally almost periodic group and any UHF algebra , there exists a strongly outer product type action of on . We also show the existence of countable discrete almost abelian group actions with a certain Rokhlin property on the universal UHF algebra. Consequently we get many examples of unital separable simple nuclear -algebras with tracial rank zero and a unique tracial state appearing as crossed products.

36 pages total. Exposition simplified: removed proofs of well-known operator algebra facts etc. Added section to emphasize the ideas of bumping up and cutting down used. Now 22 pages. Lengthy but routine proofs deferred to thesis, exposition simplified
