to determine the usefulness of the time intervals obtained from the first derivative of apex cardiogram (da/dt) in assessing contraction and relaxation, 20 hemodynamically and angiographical1y investigated patients with coronary artery disease and 29 patients with hypertensive heart disease were studied. as a control group there were used 50 normal subjects. since contraction and relaxation is ...

This article reports a study on the dielectric relaxation processes of Cd2Nb2O7 compound. Three dielectric relaxation modes I, II, and III were reexamined. By using the Cole–Cole equation fitting of the frequency dependence of dielectric constant and loss, we obtained more precise relaxation time data, compared to the data reported in the literature. The results indicate that the relaxation tim...

Iterative image restoration algorithms can better control the restoration process, but the choice of the relaxation parameters can be an inviable task. We present here a GPbased approach that stabilizes the iterative RAP-2D image restoration algorithm choosing the optimal or quasioptimal relaxation parameters that maximize the improvement signal to noise ratio of phantom images. CBERS-2 CCD ban...

Dielectric relaxation of different molar concentrations of ethanol (C2H5OH) in binary mixtures of ethanol and chlorobenzene in benzene solutions has been studied at 9.883 GHz by using standard standing microwave techniques and Gopala Krishna’s single frequency concentration variation method at different temperatures (25 ◦C, 30 ◦C, 35 ◦C, and 40 ◦C). It was found that the dielectric relaxation t...

A wide range of glassy and disordered materials exhibit complex, nonexponential, structural relaxation (aging). We propose a simple nonlinear rate equation δ = a[1-exp(b δ)], where δ is the normalized deviation of a macroscopic variable from its equilibrium value, to describe glassy relaxation. Analysis of extensive experimental data shows that this equation quantitatively captures structural r...

The study analyses the Effectiveness of relaxation therapy on the level of stress and physiological parameters among the antenatal mothers with mild pregnancy induced hypertension. Quasi experimental approach was adopted in the study to evaluate the effectiveness of relaxation therapy on the level of stress and physiological parameters. One group pre-test post-test research design was selected ...

T1, T2, and magnetization transfer (MT) measurements were performed in vitro at 3 T and 37 degrees C on a variety of tissues: mouse liver, muscle, and heart; rat spinal cord and kidney; bovine optic nerve, cartilage, and white and gray matter; and human blood. The MR parameters were compared to those at 1.5 T. As expected, the T2 relaxation time constants and quantitative MT parameters (MT exch...
