Claudia,
Oh yes, we are interested in (more) data. And I would like to suggest
some neat media too -- close to lipid and aqueous proteins in fibre
as possible - -something with EOSs close to biomaterials -- NOT gels, syrup,
blood, shrimp dung, Gator Aid, colloidal junkj,etc. Yount did a gel
thing 25
yrs ago -- but it doesn't come close to biomass. The materials props of bubs
are very fundamental under PV/T, plus fracture, especially at the 0.01
micron level (mucho eyestrain even for a e-microscope). But study
of biolike behavior at any size is cool too.
Let me connect with you on bubs study a bit later -- and info too, and
I will update you what we have done here at LANL Plus how it all feeds into
RGBM for diving -- shipping separate pdf file in separate email so as
not to further spam Lists.
On the NACD questionnaire, be sure to include Tim O'Leary
(Director, NAUI Tech Ops) at Nauitec@ao*.co*, and Tim and I know many
other worthy individuals.
Ciao.

>(2) On the last NACD board meeting, I became the new committee chair for
>equipment technology. Lamar Hires was the person to do this before and
>he is swamped with his business, which also made it difficult for
>credibility, since manufacturers have this smell of being biased. The
>board is interested in gear that is used for cave diving and especially
>its safety. We regard it as a service to the members, and for people
>involved in the manufacturing process it would be a great opportunity to
>see their equipment tested by neutral divers.
>I am essentially coordinating efforts and gear plus info from
>manufacturers, dive everything myself and have a handful of others to
>dive it and send me their reports.
>Long story short, if you would like to inform a broader audience of
>something you believe in, I would be happy to be a fair messenger. That
>being the case, I will send you a questionnaire to make things simpler
>for all people involved. That is not the format the report will be in,
>don't worry.

>Thanks, and have a good day,
