Simultaneous measurements of stress relaxation and differential dynamic modulus were made at 20°C for polyisobutylene in large shearing deformations on which intermittent small oscillations were superposed perpendicularly.
Amorphous poly ethylene terephthalate) (PET) films with different thermal histories were annealed at 30°C in a desiccator, in a humid atmosphere and in liquid water respectively, for investigation of enthalpy relaxation by differential scanning calorimetry (DSC).
The 5th and the 6th sessions comprised conditioned and differential relaxation.
The sensing circuit is based on a differential relaxation oscillator, to which multiple capacitances can be connected.
Their heat capacities (Cp) from near absolute zero (2 K) to high temperature were measured by the relaxation method and differential scanning calorimetry.
The molecular dynamics of a series of poly(dimethylsiloxane) networks filled with silica nanoparticles synthesized in situ was investigated using thermally stimulated depolarization currents, broadband dielectric relaxation spectroscopy and differential scanning calorimetry.
Structure and molecular dynamics of α,ω-dihydroxy terminated polybutadienes of varying number averaged molecular weight (1320 10 500 g/mol) have been investigated by Fourier-transformed infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, dielectric relaxation spectroscopy (DRS), differential scanning calorimetry (DSC) and wide-angle X-ray scattering (WAXS).
To correct for differential relaxation, an inversion recovery experiment using an array of delay times from 0 to 10 s was performed on both medium and cell extracts.
The program consisted of four individual 1-hour sessions of stress management with a trained therapist over 2 consecutive weeks and included applied, progressive, cue-controlled, and differential relaxation techniques, as well as psycho-education, breathing and visualization exercises.
Positional C enrichment for metabolites was determined by integration of appropriate central and C satellite peaks in one-dimensional and two-dimensional TOCSY experiments, followed by corrections for differential relaxation where necessary as previously described [ 8, 11].
