Fig. 9. (A) Young's modulus plotted against the previous strain cycle value for
each pH treatment. Threads treated at pH 5 and below show a pH-induced
reduction in modulus that becomes less prominent as the thread is cycled to
higher strain values. (B) Reduction in modulus (
E) between
strain cycles in Fig. 9A plotted against the strain that caused it for each of
the pH treatments. Asterisks indicate where
E at pH 5 is
significantly different from
E at pH 8 (P<0.01).
Values are means ± s.e.m.; N ranged from 6 to 10 threads for
each treatment.
