	abstract = {We examine, from the point of view of membrane computing, the two basic
assumptions of reaction systems, the \threshold" and \no permanence" ones. In certain
circumstances (e.g., de{\textasciimacron}ning the successful computations by local halting), the second
assumption can be incorporated in a transition P system or in a symport/antiport P
system without losing the universality. The case of the {\textasciimacron}rst postulate remains open: the
reaction systems deal, deterministically, with {\textasciimacron}nite sets of symbols, which is not of much
interest for computing; three ways to introduce nondeterminism are suggested and left
as research topics.},
