In this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. Given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (FSDT). These equations are so...

The localization of the stretch sensitivity and myogenic automatism in the systemic heart of Octopus vulgaris has been studied on an isolated preparation in which the ventricle was zoned by ligatures. Each region has been submitted to two different levels of internal hydrostatic pressure (1 and 2 kPa). Only the two atrio-ventricular regions were able to contract regularly when submitted to inte...

We studied hearts in which hypertrophy was caused by both pressure and volume overload. Pressure hypertrophy was induced by an aortic constriction; volume hypertrophy was induced by an iron-copper deficiency (anemia). The ventricular weight was increased by 34% in the pressure-hypertrophied hearts at the end of 6 weeks. The ventricular weight was increased by 54% in the volume-hypertrophied hea...

It is well known both by clinical examination and by objective measurement that a high pressure zone is to be found in the anal canal, due to the action of the anal sphincteric muscles. Division of part of the internal anal sphincter in the operation of internal sphincterotomy resulted in a diminution in this pressure zone (Bennett and Duthie, 1964). The pressure remaining after internal sphinc...

A simulated artillery chamber pressure generator (SACPG) was proposed for solving the dynamic evaluation in application environment of internal electronic pressure gauge. Strength autofrettage theory of SACPG was studied and simulated by ANSYS. Pressure waveforms, of which the amplitudes were up to 700MPa and the rise time was between 2 ms and 5 ms, had been obtained through controlling the dia...

in this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (fsdt). these equations are so...

Raman scattering from binary GexSe1−x glasses under hydrostatic pressure shows onset of a steady increase in the frequency of modes of corner-sharing GeSe4 tetrahedral units when the external pressure P exceeds a threshold value Pc. The threshold pressure Pcsxd decreases with x in the 0.15,x,0.20 range, nearly vanishes in the 0.20,x,0.25 range, and then increases in the 0.25,x,1/3 range. These ...

Large inconsistencies in previous microchannel pressure drop data have motivated the development of a microchannel experimental platform that enables the measurement of pressures inside the microchannel. The system utilizes bulk etched silicon components that integrate pressuresensing membranes with the microchannel test section. The deflection of the membranes is detected by an off-chip, optic...

Determination of energy transport is crucial for understanding the energy budget and fluid circulation in density varying fluids such as the ocean and the atmosphere. However, it is rarely possible to determine the energy flux field J = pu, which requires simultaneous measurements of the pressure and velocity perturbation fields p and u, respectively. We present a method for obtaining the insta...

  Background: Epidemiological changes leading to chronic diseases are becoming more important day by day. Hypertension is also known as a chronic disease. Worldwide prevalence of hypertension have caused serious complications. The disease has become a health problem in all communities. This research aims at analyze the correlation between compliance with the treatment regimen and health locus o...
