It 1s known that the deflection of a diaphragm 1s determmed by two mechamsms, bendmg moments or bendmg stress and tensile forces or membrane stress Usually the influence of tensile forces 1s not taken mto account when calculating the mechamcal properties of thm diaphragms Hence the mathematical descrlptlon thus obtamed will only be valid if the deflection of the diaphragm is small compared with...

Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, effect connections between floors and walls is rarely discussed or explicitly modelled when simulating response such buildings. These are most commonly timber made planks beams, which supported on recesses can slide friction resistance reached. Using equivalent frame models, we capture effects bot...

The separator is a critical component for the performance of alkaline water electrolysis as it ensures ionic contact between electrodes and prevents product gases from mixing. While conductivity affects cell voltage, permeability dissolved influences gas impurity. Currently, diaphragms are used separators, pore system which filled with electrolyte solution to enable exchange ions. breakthrough ...

Abstract Keramasan Bridge 2 is a bridge with an age of more than 30 years, so it necessary to review its feasibility and serviceability. Based on visual observations, there are signs cracks in the transverse longitudinal directions floor. results loading test, stated that deflection girder has exceeded allowable deflection, cause floor crack caused by non-uniform vertical movement girder. this,...

A novel structure of the resonant pressure sensor is presented in this paper, which tactfully employs intercoupling between dual pressure-sensing diaphragms and a laterally driven resonant strain gauge. After the resonant pressure sensor principle is introduced, the coupling mechanism of the diaphragms and resonator is analyzed and the frequency equation of the resonator based on the triangle g...

Perfusion of the fenestrated capillaries of the intestinal mucosa of the rat with 0.05-0 .1 M EDTA removes the diaphragms of the endothelial cells and detaches these cells from one another and from the basement membrane . The latter, even when completely denuded, retains effectively particles of 340 A (average) diameter. Perfusion with histamine (1 μg/ml) results in partial removal of fenestral...
