Mechanical stress in phonation
Journal of Voice, 1994Mechanical stress is always encountered in phonation. This includes tensile stress, shear stress, impact stress during collision, maximum active contractile stress in laryngeal muscles, inertial stress, and aerodynamic stress (pressure). Order of magnitude calculations reveal that tensile stress can reach the greatest value (near 1.0 MPa), contractile ...

Fibronectin is up‐regulated in podocytes by mechanical stress
The FASEB Journal, 2019Hypertension is one of the central causes of kidney damage. In the past it was shown that glomerular hypertension leads to morphologic changes of podocytes and effacement and is responsible for detachment of these postmitotic cells. Because we have shown

Voltage hysteresis of lithium ion batteries caused by mechanical stress.
Physical Chemistry, Chemical Physics - PCCP, 2016The crucial role of mechanical stress in voltage hysteresis of lithium ion batteries in charge-discharge cycles is investigated theoretically and experimentally. A modified Butler-Volmer equation of electrochemical kinetics is proposed to account for the

Impact of mechanical stress on ferroelectricity in (Hf0.5Zr0.5)O2 thin films
, 2016To investigate the impact of mechanical stress on their ferroelectric properties, polycrystalline (Hf0.5Zr0.5)O2 thin films were deposited on (111)Pt-coated SiO2, Si, and CaF2 substrates with thermal expansion coefficients of 0.47, 4.5, and 22 × 10−6/ °C,

Mechanical Stress Regulates Bone Metabolism Through MicroRNAs
Journal of Cellular Physiology, 2016There are many lines of evidence indicating that mechanical stress regulates bone metabolism and promotes bone growth. BMP, Wnt, ERK1/2, and OPG/RANKL are the main molecules thought to regulate the effects of mechanical loading on bone formation ...

The Virial Stress Is Not a Measure of Mechanical Stress
MRS Proceedings, 2002AbstractThe virial stress is the most commonly used definition of stress in discrete molecular systems. This stress includes two parts. The first part depends on the mass and velocity of atomic particles, reflecting an assertion that mass transfer causes mechanical stress to be applied on stationary spatial surfaces external to an atomic particle ...

We shall continue now the theoretical study of the preceding chapter, by putting in evidence the stresses which arise because of the deformation of a solid body; both vector and tensor aspects of the stress are thus emphasized.

Mechanisms of Stress (Takotsubo) Cardiomyopathy
Heart Failure Clinics, 2013Stress cardiomyopathy is a form of reversible systolic dysfunction of the mid and apical left ventricle with pathologic changes of the electrocardiogram in the absence of an obstructive coronary artery disease. The prevalence of stress cardiomyopathy among patients with symptoms suggestive of myocardial infarction is 0.7% to 2.5%, and it is found ...

Bone has been known to adapt to mechanical stress (Amin 2010; Beier and Loeser 2010; Currey 2010; Temiyasathit and Jacobs 2010). The presence of mechanical stress increases bone mass and the absence of mechanical stress reduces bone mass. Bending of weight-bearing long bone increases pressure on the concave side and decreases it on the convex side ...

Mechanical stress is developed in optical systems from various internal and external influences, including inertial, pressure, dynamic, temperature, and mechanical loads. Excessive stress can lead to permanent deformations of optical mounts and support structures by exceeding the yield strength of the material resulting in misalignments of optical ...
