X-Message-Number: 3910 From: Date: Sun, 26 Feb 1995 20:44:11 -0500 Subject: SCI. CRYONICS damage assessment Richard Schroeppel (#3845) had some questions about cracking. Some brief answers are: Yes, we plan (as necessary) to repeat/verify all procedures that have been used and the results in re cracking, as well as other possible deficits. I believe we will get cooperation in this from Alcor and BioPreservation. One hypothesis on cracking is that it occurs if cooling/warming is too fast in certain critical temperature ranges. The possibility that cracking might occur over time in liquid nitrogen seems implausible to me, but will be investigated. The cheerful aspect of all this--in addition to hopefully eliminating the cracking problem--is that we will probably settle all objective questions pertaining to damage by present techniques in a relatively short time, perhaps as little as a year.
