The presence of membrane proteins in a concentration of 60 micrograms.ml-1 induced a significant decrease in parameter E (to approx.
(18) While the modulus values for relatively large specimens (h greater than 500 microns) remained fairly constant (approximately 15 GPa), the values decreased as the specimens became smaller.
(19) Ultimate tensile strength, yield strength, modulus of elasticity, and Brinell hardness values for the alloys were comparable.
(20) The elastic modulus of the vesicle membrane was obtained by an osmotic swelling method.

(6) Use of the improved operative technique contributed to reduction in number of complications.
(7) Life expectancy and the infant mortality rate are considered more useful from an operational perspective and for comparisons than is the crude death rate because they are not influenced by age structure.
(8) Together these results suggest that IVC may operate as a selective activator of calpain both in the cytosol and at the membrane level; in the latter case in synergism with the activation induced by association of the proteinase to the cell membrane.
