Maintenance of relaxation-induced blood pressure reductions: the importance of continued relaxation practice.
This study examined the long-term importance of continued relaxation practice in the maintenance of relaxation-induced blood pressure reductions. An ABAB withdrawal-reinstatement design was employed with two hypertensive subjects. An objective, unobtrusive measure of home relaxation practice was used to monitor compliance. Subject 1 showed substantial reductions in systolic and diastolic blood ...
متن کاملCation-Exchange Kinetics on Montmorillonite Using Pressure-Jump Relaxation
Batch and flow methods are usually not suitable for measuring kinetics of ion-exchange reactions on soils and soil constituents. These reactions are usually very fast. Thus, a rapid kinetic method must be employed. A pressure-jump relaxation technique was used in this study to investigate the kinetics of Ca-Na and Ca-K exchange on montmorillonite. Single relaxations were observed in both system...
متن کاملPressure relaxation of the left ventricle and filling pressures.
going dobutamine-stress (2). However, the PET technique enabled us to detect very early changes in myocardial blood flow before these clinical signs of ischemia eventually developed. Since we know that the presence of clinical signs of ischemia are inconsistent, subjective and variable in the same patient, we decided to focus on quantifiable, regional measures of myocardial blood flow. In contr...
متن کاملReynolds pressure and relaxation in a sheared granular system.
We describe experiments that probe the evolution of shear jammed states, occurring for packing fractions [symbol: see text](S) ≤ [symbol: see text] ≤ [symbol: see text] J, for frictional granular disks, where above [symbol: see text]J there are no stress-free static states. We use a novel shear apparatus that avoids the formation of inhomogeneities known as shear bands. This fixed [symbol: see ...
متن کاملRelaxation Dynamics of Poly(methyl acrylate) at Elevated Pressure
A fascinating aspect of the dynamics of supercooled liquids and polymers is the degree to which the reorientational or segmental relaxation time, τR, governs various properties. 1,2 For example, the shape of the relaxation peak, commonly reflected in the Kohlrausch stretch exponent, the state points associated with the dynamic crossover, and the dynamic correlation volume for many glass formers...
