709 approximates central aortic systolic pressure than does a direct arterial recording at the same site or from the radial artery. In clinical exercise testing, a key function of blood pressure monitoring is to detect exercise-induced hypotension. This has been defined as failure of the systolic blood pressure to increase progressively with increasing workload2 and, in patients with coronary a...

This paper describes the use of proximity transducers to accurately measure the radial and circumferential normal strains of the test specimen (covering the pseudo elastic range to shear failure) in a hollow cylinder apparatus. The non-contact proximity transducers, which were located in the outer cell chamber and the inner bore cavity of the specimen, measure the radial displacements of the in...

The aim of this paper is to determine the critical buckling load for simply supported thin shallow spherical shells made of functionally graded material (FGM) subjected to uniform external pressure. A metal-ceramic functionally graded (FG) shell with a power law distribution for volume fraction is considered, where its properties vary gradually through the shell thickness direction from pure me...

In this paper,fluidity onset analysis in FG thick-walled spherical tanks under concurrent pressure loading and heat gradient has been presented. Designing thick-walled spherical tanks under pressure as tanks holding fluids under heat loads with high heat gradients require new approaches. Under high internal pressure and high temperature, the tank enters the plastic stage in a part of its thickn...

40 Cardiac output measurement from arterial pressure waveforms presumes a defined relationship 41 between the arterial pulse pressure (PP), vascular compliance (C) and resistance (R). Cardiac 42 output estimates degrade if these assumptions are incorrect. We hypothesized that sepsis would 43 differentially alter central and peripheral vasomotor tone decoupling the usual pressure wave 44 propaga...

One-dimensional modeling of steady frictional radial flow of a perfect gas through a high-pressure piezoelectrically actuated microvalve under low leak-rate conditions is studied. Focusing on the micro-scale gap between the boss and seat plates, a model was developed for axisymmetric flow between two thermally insulated, parallel disks flowing radially toward an outlet hole at the center of the...

as the molecules approach under the application of pressure. We expect that high-pressure Raman study will provide further insight into the vibrational and bonding properties in solid Cso The pressure behavior of a “squashing” mode, a radial distortion from the spherical shape into an ellipsoid, is particularly interesting in comparison with the softening observed for the IF,, radial mode. A hi...

A theoretical study of radial flow chromatography was carried out based on a general nonlinear multicomponent rate model which considers radial dispersion. external mass transfer, intraparticle diffusion. and nonlinear multicomponent isotherms. Radial dispersion and mass transfer coefficients were treated as variables which are dependent on the radial coordinate of the radial flow column. The m...
