Re: [Obi-role-branch] [Obi-devel] emulsion

we are in the same boat.  possibly a good thing to do before the
workshop.  the role branch is workign on meeting previous milestones,
which will then make it possible for folks to review our work.

Subject: Re: [Obi-devel] emulsion


Hi,
> emulsion
We worked on this term and others (solution, suspension, lysate) prior
to the June workshop.
Currently in Biomaterial def: "A mixture of immiscible (unblendable)
substances, that are finely dispersed and not separate through the
action of gravity alone".
Maybe somebody should review the all set of terms currently under
Biomaterial and suggest changes*. Any volunteers?
Thanks,
Susanna

* We have no luck in organizing a branch call, unfortunately.=20
But on the other hand we have not received new terms so far a part from
Bjorn's.

	i agree with this, as long as this conclusion is ok with the
biomaterials branch.
	was this their decision?

	HI,

		we had a question about whether emulsion was a
biomaterial or a role.=20
		two ways to look at it...


	Its neither, its an arrangment of form, or state. In the state
of emulsion chemicals play the role of the dispersed phase or the
continuous phase.=20

		(1) i have created an emulsion via mixing part A with
part B; the point of focus is the emulsion, which is probably a
biomaterial

		(2) i have stuff A, which i need to get into an animal,
and the best way to do it is to mix with part B, creating an emulsion.
the point of focus is part A, which may be playing a role of being
emulsified if it is important to record this.=20

		in either case, if there is strong feeling that
emulsions can only be considered to be biomaterials, i can live with
this and just omit this detail if i am only describing part A.
