In mechanics, strain is defined as relative deformation, compared to a reference position configuration. Different equivalent choices may be made for the expression of a strain field depending on whether it is defined with respect to the initial or the final configuration of the body and on whether the metric tensor or its dual is considered.
Neutrophils extravasate from blood vessels to the site of tissue injury or infection during the innate immune response.. In immunology, leukocyte extravasation (also commonly known as leukocyte adhesion cascade or diapedesis – the passage of cells through the intact vessel wall) is the movement of leukocytes (white blood cells) out of the circulatory system (extravasation) and towards the ...
In continuum mechanics, the finite strain theory—also called large strain theory, or large deformation theory—deals with deformations in which strains and/or rotations are large enough to invalidate assumptions inherent in infinitesimal strain theory. In this case, the undeformed and deformed configurations of the continuum are ...
Strain means Deformation, and is defined as relative change in length.The Lagrangian formula ε L = (L-L 0)/L 0 = ΔL/L 0, where L 0 is baseline length and L is the resulting length, defines strain in relation to the original length as a dimensionless measure, where shortening will be negative, and lengthening will be positive.
A structure is called a plate when it is flat and one of its dimensions is much smaller than the other two. There are several theories that attempt to describe the deformation and stress in a plate under applied loads two of which have been used widely. These are the Kirchhoff–Love theory of plates (also called classical plate theory)
All blood cells are divided into three lineages. [9] Red blood cells, also called erythrocytes, are the oxygen-carrying cells. Erythrocytes are functional and are released into the blood. The number of reticulocytes, immature red blood cells, gives an estimate of the rate of erythropoiesis. Lymphocytes are the cornerstone of the adaptive immune ...
Officials say two migrant teens were victims in a New York City stabbing, one fatally, after the teens were asked if they spoke English and they responded that they didn't. Police say they were ...
For example, the muscle tone of the smooth muscle tissue of the tunica media can be adjusted by the renin–angiotensin system. In patients whose endogenous homeostatic regulation is not working well, dozens of pharmaceutical drugs that are also vasoactive can be added. The response of vessels to such vasoactive substances is called ...
