Straining to justify strain measurement.
A broad array of cardiac imaging research and technique development has been deployed in the quest to define the earliest myocardial changes of cardiomyopathy so that earlier detection may afford more timely institution of therapy and improved outcomes. Recognition that high-resolution measures of myocardial deformation can be abnormal before global contractile dysfunction has further fueled de...
متن کاملStraining Graphene Using Thin Film Shrinkage Methods
Theoretical works suggest the possibility and usefulness of strain engineering of graphene by predicting remarkable properties, such as Dirac cone merging, bandgap opening and pseudo magnetic field generation. However, most of these predictions have not yet been confirmed because it is experimentally difficult to control the magnitude and type (e.g., uniaxial, biaxial, and so forth) of strain i...
متن کاملEffect of straining on the muscles of the anterior abdominal wall. Identification of the 'straining-abdominal wall reflex'.
The external and internal oblique, transverse abdominis and the rectus abdominis muscles constitute the anterolateral abdominal wall muscles. They are striated and contract voluntarily. We investigated the hypothesis that contraction of these muscles by coughing or straining, can also occur as a reflex. Effect of straining on muscles was tested in 19 healthy volunteers. The intra-abdominal pres...
متن کاملThe Emphysema Response to Forced Straining
R ECENTLY there has been a renewed interest in the physiologic effects of forced straining (Valsalva's maneuver). Particular emphasis has been placed on the blood pressure changes during and immediately after forced straining in an attempt to define more accurately the diagnosis of certain circulatory abnormalities, particularly hemodynamically significant mitral stenosis and the presence of co...
متن کاملStraining flow of a micellar surfactant solution
We present a mathematical model describing the distribution of monomer and micel-lar surfactant in a steady straining flow beneath a fixed free surface. The model includes adsorption of monomer surfactant at the surface and a single-step reaction whereby n monomer molecules combine to form each micelle. The equations are analysed asymptot-ically and numerically and the results are compared with...
