	abstract = {Starting from proofs of results about the computing power of conformon-
P systems, we infer several results about the power of certain classes of tissue-like P
systems with (cooperative) rewriting rules used in an asynchronous way, without cycles
in compartments. This last feature is related to an important restriction appearing when
dealing with lab implementations of P systems, that of avoiding local evolution loops of
objects.},
