nical support during this undertaking. Furthermore, his enthusiasm toward the work was
truly motivational. A special thank you is extended to Dr. Ronald F. Wukasch and Dr.

Candace Carter, fellow graduate student and employee of Naval Air Warfare
Center-Aircraft Division-Indianapolis, is deserving of recognition because of her invalu-
able assistance in procuring critical elements of the test apparatus. She was also instru-
mental in arranging for a portion of the analytical analysis to be performed by
NAWC-AD-Indianapolis. The backing received from all fellow graduate students is
appreciated but the assistance provided by Gretchen Hein and Brad Blank in the final
hours is worthy of mention.
Financial support from the Naval Civil Engineering Laboratory (Port Hueneme,
CA), is gratefully acknowledged. The author is also indebted to FilmTec Corporation
(Minneapolis, MN) for providing the membrane samples and especially to Mr. Tim Berg
of NAWC-AD-Indianapolis for performing analytical analyses.
