These thin, scroll-shaped bones or cartilage appear in the nasal passages of almost all modern endotherms
, according to physiologists John A.
The DSC curves show double endotherms
in the melting region for i-PP during the scanning process as observed for the lower molecular weight untreated PP fibers.
But physiologist John Ruben of Oregon State University in Corvallis argues that Barrick and Showers have jumped to conclusions without studying enough about modern endotherms
To investigate the origin of the duplicated melting endotherms
, the WAXS analysis was carried out on the samples (Fig.
Because the bones of mammals and other endotherms
do not show growth rings, their presence in Syntarsus links that animal with ectotherms.
c]) is calculated by dividing the melt enthalpy of samples (the area under the endotherm
peak in DSC curve obtained while investigating melting behavior) by the melt enthalpy of the samples with 100% crystallinity ([DELTA][H.
g] and a melting endotherm
were observed, but no cold crystallization was observed for any of the multiblock copolymers.
Figure 7 shows the melting endotherms
of the samples taken from the different sections of the miniaturized specimen.
Furthermore, only this blend has shown a relevant shift of the all melt endotherms
with respect to other ternary blends.
Different melting DSC endotherms
for segmented PUs based on different diisocyanates.
Thus, the endotherms
centered at 144[degrees]C, 183[degrees]C, and 198[degrees]C in the LCC appeared at lower values in the composites containing the greatest amount of liquid crystal [94[degrees]C, 156[degrees]C, and 180[degrees]C (a), 87[degrees]C, 153[degrees]C, and 181[degrees]C (g), and 82[degrees]CC, 150[degrees]C, and 181[degrees]CC (h)] as can be seen in Table 2.
No melting crystallization exotherms or endotherms
of chain relaxation near the glass transition temperature were detected for the cold drawn fiber, which also indicated that the polymer chains were highly orientated.
