However, guanidinium derivatives for detection of aortic relaxation were not observed except agmatine and amiloride which induced a marked relaxation in isolated aortic rings precontracted with phenylephrine or KCl.
Direct quantitative detection of the relaxation behaviors of thin polymer films at nanometer scale by traditional instruments is however challenging.
In the case of the resins cured with aromatic amines, for which no γ relaxation is evidenced by DMA, creep rate spectroscopy allowed the detection of an additional relaxation, so called γ′, at temperatures well below the β process.
The detection of the chemical relaxation effect predicted by Nernst and Einstein did not become technically feasible until the last half of the 20th century.
But in contrast to our results they did not observe a significant effect of relaxation on detection thresholds.
E′ is also useful in the detection of impaired left ventricular relaxation and estimation of filling pressure (E/E′) in patients with atrial fibrillation [ 70].
At the higher CR:aS ratio of 4, region I is attenuated beyond detection, but relaxation properties of resonances for region II, which are attenuated by ∼50%, yield some insights into its interaction with CR.
Next to the segmental dynamics (α relaxation) of the bulk-like polymer related to the glass transition, BDS allowed the detection of a separate segmental-like relaxation of the polymer in the interfacial silica-PDMS zone.
For these reasons, the detection of muscles activities in a relaxation phase, defined in time interval t1 and t2 (in Figure 1) could not perform well visually directly from s k,u n or s ( k, u, j, λ ( j ) ) [ n ].
