The results of RNA leakage tests revealed that direct contact of the bacteria with GO causes membrane stress, leading to irreversible damage.
Thus, it is important to accurately understand the size of the membrane stress after the completion of the structure for maintenance and management purposes.
Our results on structural integrity of the outer membrane have some degree of relationship on previous research on role of tolC deletion on integrity of the outer membrane defects such as depletion of essential metabolites, cytoplasmic membrane stress and alteration in NAD+/NADH ratios have been reported in literature (Dhamdhere and Zgurskaya, 2010).
Evidence that membrane stress contributes more than lipid peroxidation to sublethal cryodamage in cryopreserved human sperm: glycerol and other polyols as sole cryoprotectant.
The critical stress in the case of a membrane stress state for thin elastic shells may be presented by a similar formula in many cases: of a closed spherical shell under uniformly distributed normal pressure, of a circular cylindrical shell under central axial loading, and of a conical shell of revolution under central axial loading.
In the above equation, [[tau].sub.cr] refers to the elastic critical shear stress in the web, [[sigma].sup.y.sub.t] the membrane stress in the web in post-critical stage, b, web panel width, c, distance between the hinges formed in the flange, d, web depth, t, web thickness, [M.sub.pf], plastic moment of the flange and [theta], the angle of inclination of the tensile membrane stress [[sigma].sup.y.sub.t].
Decrease Methods of Stress Concentration Around theHolesIn shell structures under internal stress loadings and uniform axis tensile, if there is no hole, there will be no bendingstress; only a fixed membrane stress develops in everywhere,one type of material and thickness is applicable for all points of the structure.
Like alkaline pH response which is mediated through the calcineurin signaling cascade, we tested the remaining phenotypic response such as serum stress, ER stress, ionic stress, and membrane stress in presence of Ses.
Thus standard edge stress measurement gives us the value of the edge stress [[sigma].sub.e], the average membrane stress [[sigma].sub.m] through the thickness in the area A and the surface stress [[sigma].sub.s].
A likely explanation is that capillary sampling results in increased erythrocyte membrane stress, thereby causing an increased leakage of cations such as potassium, whereas proteins such as LDH and hemoglobin remain intracellular.
In the old days it was easy; just fully adhere the roof membrane with a lot of goop directly to the structural deck so that each square foot of roof membrane stress was directly transferred to the square foot of structural deck directly under the membrane.
al [4]describe the radial stress [f.sub.R] (equation 6) in the flange ring consists of two components, the bending stress caused by the radial bending moment and the membrane stress caused by in-plane surface loads on the inside diameter.
