Need help to find paper: "Cold Water Exposure Guidelines by E.D. Thalmann"

[_blackdiver_]

Hello board members,

I hope that this "shout for help" is at the right place here in the Marine Science and Physiology board.

For a summery project I am looking for a paper:

"Thalmann, E.D. and R.P. Weinberg. 1990. Cold Water Exposure Guidelines for Passive
Thermal Garments. NMRC Work Unit 639113N M009.01B-1004."

That was also probably published in "Undersea Biomedical Research" Issue 17.

I found a reference to it in

"SURVEY OF THERMAL PROTECTION STRATEGIES" by Robert T. Stinton, Diving Unlimited International:
....
Thalmann in Cold Water Guidelines for Passive Thermal Garments (1990) presented a simple algorithm to generate an exposure table. The algorithm can be set up on a Microsoft Excel spreadsheet and takes into account the following parameters: desired end of exposure functionality, water temperature, size of the diver, and the activity level.
...."

Maybe someone can help me. It looks like that the magazine doesent exist anymore/ was renamed, archive goes to the rubicon foundation / GUE (the paper ist listed at rubicon, but not available/scanned for download) and Mr Thalmann passed away some years ago I am living in germany what makes it difficult to search for it in a library... any ideas, links or PDF's ?

Hi _blackdiver_,

This item was only published as an abstract; a journal article is not available for download.

Abstract:

"Criteria for thermal garment design adopted by the U.S. Navy in 1980 are based on a change in body enthalpy of 3 Kcal/Kg with a minimum skin temperature (Tsk) of 20°C. Current experience suggests that these limits are too permissive. Newly proposed criteria are based on functional categories that specify net body heat loss (s) based on combinations of Tsk and rectal temperature (T) obtained from actual in-water exposure^sk: s = (69.73) (0.83) [0.65 (37 -Tre) + 0.35 (33 -Tsk)] .wt (1) [s in watts·min, body weight (wt) in Kg]. Metabolic rate was estimated from the steady state relationship proposed by Wissler (1): Q = 103 + [2.70 . (Tre-41.0) (Tsk-41.8) -97.62] (2) [Q in watts]. The basic heat flow equation: s =[Q-6.45 (Tsk-Tamb) . SA/INS] .time (3) [Tamb = water temp, SA = body surface area (m^2), INS = insulation (CLO), time in min] is solved for time using values of sand Q from equations (1) and (2). Criteria for full function assumed T > 36.5, T > 29. Q = 161 (oxygen consumption ~ 0.5 l/minute). plots of time vs Tamb for various levels of insulation are made. Resultant exposure times appear reasonable. Separate limits for hands and feet were based on minimum digit temperatures of 12°C for adequate function. Methods of determining suit ensemble insulation were also developed. Ref: (1) Chapter 13, Heat Transfer in Medicine and Biology, Vol. 4, 1985. A. ****zer and R. Eberhart, eds. Plenum Press, New York."

The Duke Medical Center Archive has a number of Thalmann's Research papers and work. Not sure if they have this specific item but might be worth checking out.

Hi DocVikingo,

thanks for your answer but there are too many unexplained factors/values in the equatations of the abstract.
Thats why I am looking for the complete article.

Regards,

Alex

I don't think this is a paper at least not a published paper since the abstract is for a meeting. I suspect that it was either an oral presentation or a poster.

I think this paper might help though,
