you know, i've never seen the need to check that out. i've just presumed that
relatively-passive ionic conductance would occur via mechanisms different from
the mechanisms of relatively-active ionic conductance... or else there'd be no
difference in the ionic conductances.
i'll make a 'mental note' to be on the lookout for information pertaining to
such.
seems to me, from the way you're zeroing-in on particular things, that you have
a particular 'goal' in mind.
why not state such, and outline your underlying premise?
to be specific, i'm 'wondering' if this's is another instance in which a
relatively-small consideration is being 'set-up' as being 'equivalent' to the
entirity of NDT's stuff?
i get such all the 'time'. not once has anything anyone's brought up, in this
way, made any negative difference with respect to NDT's synthesis. it's always
been the case that NDT's stuff has only gotten-stronger as a result of the
information exchanged.
so, i hope you'll continue... only, please continue without any more 'beating
around the bush'.
