During the α-relaxation the trend of E′, E″ and tan δ with temperature, and at multiple frequencies, evidenced the overlapping of phenomena.
Mechanical aging rates determined from time aging time superposition of creep compliance data showed significantly less than additive behavior for the blends aged at Tg−30°C, but unlike the volume relaxation results, this trend persisted at the 60°C undercooling.
The trend in relaxation behavior with increasing oil content measured by single-sided NMR was found to be the reverse of that obtained by conventional benchtop NMR.
The use of tools based on classical form-finding procedures as dynamic relaxation is the main trend today; different mechanical models with 3, 4 or 6 degrees of freedom have been implemented for modelling the bending effect.
In a small randomised study (n = 16), relaxation training yielded a trend toward lower levels of hot flushes and night sweats, and a significant positive effect on psychological distress as compared to a control condition.
All Doppler parameters of diastolic function differed significantly among groups in univariate analysis, showing a trend to abnormal relaxation associated with worsening of glycemic control (all P < 0.05).
This pattern was seen in P0 mice, and there was a trend toward increased relaxation in WT females vs. WT males, but this did not reach significance (P = 0.29; two-way ANOVA).
We observed a trend towards reduced relaxation in vessels treated with either Ad.shNRP1 or Ad.shNRP2 compared with Ad.shScrambled, but the differences were not statistically significant (see Supplementary material online, Figure S7B, Table S5 ).
A comparison of the decays of the correlation functions clearly unveils a faster relaxation with increasing temperature; this trend is stronger for the samples with the highest concentration and it suggests a temperature-induced compaction of the species.
Both self-assembled and chloroform cast matrices had similar trends in stress relaxation behavior.
