Strain and strain rate echocardiography
Current Opinion in Cardiology, 2002Strain and strain rate echocardiography is an emerging technique for assessing myocardial systolic and diastolic function. It is envisioned that this modality could change the quantitative assessment of regional wall motion and improve the accuracy and reproducibility of test readings. Myocardial strain and strain rate can detect inducible ischemia and

Strain and Strain Rate Imaging in Cardiomyopathy
Echocardiography, 2009The most common indication for an echocardiogram is for the assessment of left ventricular (LV) function and, in the evaluation of cardiomyopathy (CM), this becomes even more important. However, conventional echocardiographic measures of ventricular function are insensitive at detecting subtle perturbations in contractility.

Archive for Rational Mechanics and Analysis, 1988
The author is pointing out some local properties of finite and infinitesimal deformation of a continuum. We mention here some of these properties. Let x be the place of the particle X in deformation \(x=x(X)\). It is shown that at every place x there exists at least a plane such that there is no shearing for all material elements instantaneously in ...

Straining the Strain Diagnosis
2020Abstract In this case, a woman in her late 30s was brought to the emergency department (ED) following a motor vehicle collision. She was a passenger in a car that was T-boned on the passenger side. Her principal complaint was neck pain. After plain radiographs showed no bony injury, she was discharged with cervical strain.

Strain and strain relaxation in semiconductors
Journal of Materials Science: Materials in Electronics, 1997Single-crystal semiconductor layers can be grown with large coherency strains. This review covers their standard elasticity theory and methods of measuring the strain. High-quality strained layers are thermodynamically stable up to a critical thickness, and both theoretical and experimental determinations of critical thickness are considered.

Adductor Strain (Groin Strain)
2017Adductor tendonitis is pain at the medial groin secondary to injury to the adductor muscle group or its insertional site. It is believed to be caused by inflammation and collagen dysfunction due to microtrauma during activities that require bursts of speed or quick directional changes.

Plane-Strain Bending With Isotropic Strain Hardening at Large Strains
Journal of Applied Mechanics, 2010Finite deformation elastic-plastic analysis of plane-strain pure bending of a strain hardening sheet is presented. The general closed-form solution is proposed for an arbitrary isotropic hardening law assuming that the material is incompressible. Explicit relations are given for most popular conventional laws.
