objective: endothelium is a selective and permeable membrane for transferring nutrients and vital components to arterial wall. endothelial damage might lead to altered biological function of endothelium and clinical consequences such as atherosclerosis. blood pressure pulse always exerts circumferential tension to the arterial wall. hence, such tension together with other loads, play important ...
We tested the hypothesis that mechanical tension in the cytoskeleton (CSK) is a major determinant of cell deformability. To confirm that tension was present in adherent endothelial cells, we either cut or detached them from their basal surface by a microneedle. After cutting or detachment, the cells rapidly retracted. This retraction was prevented, however, if the CSK actin lattice was disrupte...
Tension stiffening behavior of post-cracking concrete is an important phenomenon which has been extensively studied for reinforced concrete structures. Although externally bonded fibre reinforced polymer (FRP) composites are widely used for strengthening existing RC structures, it remains unclear to what extent the tension stiffening of post-cracking concrete is quantitatively influenced by the...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
We introduce an anisotropic mean-field approach for the dynamics of semiflexible polymers under tension. The theory is designed to exactly reproduce the lowest order equilibrium averages of a stretched polymer, and includes the non-trivial influence of long-range hydrodynamic coupling. Validated by Brownian hydrodynamics simulations, the theory is highly accurate over a broad parameter range, e...
