Background : Coronary and artery diseases are amongst the most common existed diseases in human societies. Thus considering too much stress that is created after myocardial infarction and the effect which anxiety can have on the treatment process of myocardial infraction patients, This research was carried out to study the effect of applying progressive muscle relaxation of these patients. ...

abstract introduction: hypertension is one of the most prevalent chronic diseases worldwide. because of its chronicity, hypertension requires life-long therapy. many patients tend to discontinue therapy and seek alternative treatments. in this study, we evaluated the efficacy of two behavioral therapeutic techniques, namely relaxation and biofeedback-assisted relaxation in reducing blood pressu...

Relaxation in glass-forming liquids occurs as a multi-stage hierarchical process involving cooperative molecular motion. First, there is a "fast" relaxation process dominated by the inertial motion of the molecules whose amplitude grows upon heating, followed by a longer time α-relaxation process involving both large-scale diffusive molecular motion and momentum diffusion. Our molecular dynamic...

The dielectric behavior of poly(vinyl alcohol) –PVA– crosslinked hydrogels obtained by the repeated freezing/ thawing (F/T) technique have been investigated by dielectric relaxation spectroscopy (DRS) and differential scanning calorimetry (DSC). The crosslinked polymer is produced by the clustering of chains caused by the association of a polar group of the dissolved polymer followed by polymer...

In order to clarify the molecular mechanism of the reorientation of adsorbed water in wood cell wall during dielectric relaxation process, the temperature and frequency spectrums of the dielectric relaxation process based on adsorbed water in wood, acetylated wood and formaldehyde-treated wood were measured, respectively, within a range of -60-20°C, 30Hz-3MHz and 0-27%m.c. On this basis, the qu...

We identify a new mechanism of internal dissipation of rotational kinetic energy in spinning dust grains, arising from the reorientation of nuclear angular momentum, e.g., spins of protons. Grain rotation induces magnetization of the nuclear spin system, with net alignment of nuclear spins parallel to the grain angular velocity. When the grain does not rotate around a principal axis, the nuclea...

The author introduces his approach for breath training and relaxation therapy. He describes a process model of relaxation practice, which individualizes interventions according to each patient’s experience of relaxation. The training is supported by seven outcome categories of training and 50 standardized instructions for the relaxation process. The author advocates a systems view of breathing ...

Stopless flow operation of asymmetrical flow field-flow fractionation (FFF) has been achieved by introducing a hydrodynamic relaxation method using a frit inlet. By using frit inlet injection, a focusing process which has been an essential part of runs at the asymmetrical flow FFF system can be completely avoided. Band broadening of an initial sample zone during hydrodynamic relaxation is discu...

Numerical modelling of coherent spin relaxation in nanomagnets, formed by magnetic molecules of high spins, is accomplished. Such a coherent spin dynamics can be realized in the presence of a resonant electric circuit coupled to the magnet. Computer simulations for a system of a large number of interacting spins is an efficient tool for studying the microscopic properties of such systems. Coher...
