Strain-rate sensitivity of glasses
AbstractWe report on the loading-rate dependence of localized plastic deformation in inorganic covalent, metallic, ionic and superionic glasses. For this, the strain-rate sensitivity is determined through instrumented nanoindentation in a load-controlled strain-rate jump test. Through relating the strain-rate sensitivity to the reduced temperature, the

Recent advances in echocardiography: strain and strain rate imaging [PDF]
Deformation imaging by echocardiography is a well-established research tool which has been gaining interest from clinical cardiologists since the introduction of speckle tracking. Post-processing of echo images to analyze deformation has become readily available at the fingertips of the user.

Strain and strain rate echocardiography in children with Wilson’s disease [PDF]
This study aimed to evaluate strain and strain rate echocardiography in children with Wilson's disease to detect early cardiac dysfunction.In this study, 21 patients with Wilson's disease and a control group of 20 age- and gender-matched healthy children were included.

Cytoplasmic strains and strain rates in motile polymorphonuclear leukocytes
A new method is presented to measure local cytoplasmic deformation and rate of deformation in motile active neutrophils. The deformation is expressed in terms of biomechanical strains and strain rates. For this purpose small phagocytosed latex microspheres were used as intracellular markers. Planar Lagrangian and Eulerian strains and the rate of strain

The strain amplification is one of the recognized causes of the reinforcement of rubber by carbon black. We evaluated strain amplification in nonequilibrium, i.e., stress-strain measurements. Carbon-black-filled rubber compounds were used. In these examples, not only strain but also strain rate is amplified, since it is a dynamic situation. Because the

Strain and strain rate: An emerging technology in the perioperative period
Newer noninvasive parameters are being used for perioperative detection of myocardial ischaemia. TDI and global strain rate are some of these parameters. TDI signal is a modification of the routine Doppler flow signal. It is obtained by using thresholding and filtering algorithms that reject echoes originating from the blood pool (by-passing the high ...

Measurement of Strain and Strain Rate by Echocardiography
Strain and strain rate (SR) are measures of deformation that are basic descriptors of both the nature and the function of cardiac tissue. These properties may now be measured using either Doppler or two-dimensional ultrasound techniques. Although these measurements are feasible in routine clinical echocardiography, their acquisition and analysis ...

The most widely used method for evaluating cardiac function is transthoracic echocardiography, and myocardial function is assessed from M-mode or two-dimensional images. These modalities have significant limitations, and tissue Doppler imaging (TDI) has been introduced as a more objective ...
