This paper describes a capacitive absolute-pressure sensor in which the sealed lead transfer is eliminated. The pick-off capacitance is between a flap or skirt-like extension of the flexible diaphragm that reaches past the sealed cavity, and an electrode patterned on the substrate directly below this extension. The sidewall of the cavity is relatively narrow and flexible. Finite-element analysi...

Application of compression stockings to the lower extremities is a widely used therapeutic intervention to improve venous return, but there is little information about the effects of compression on local arterial perfusion. Therefore, we tested the hypothesis that a positive external pressure increases forearm perfusion. The relation of increasing external pressure induced by standardized compr...

BACKGROUND Auto-positive end-expiratory pressure (auto-PEEP) may substantially increase the inspiratory effort during assisted mechanical ventilation. Purpose of this study was to assess whether the electrical activity of the diaphragm (EAdi) signal can be reliably used to estimate auto-PEEP in patients undergoing pressure support ventilation and neurally adjusted ventilatory assist (NAVA) and ...

The objective of this paper is to provide guidance for the design of the thick-walled cylinder made up of transversely isotropic material so that collapse of cylinder due to influence of internal and external pressure can be avoided. The concept of transition theory based on Lebesgue strain measure has been used to simplify the constitutive equations. Results have been analyzed theoretically an...

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...

The anal sphincter is made up of the internal and external sphincter, which are arranged concentrically around the anal canal; they overlap except in the most distal part of the anal canal in the region of the superficial part of the external sphincter. Continuous electromyographic (EMG) activity may be recorded in the external anal sphincter at rest (Floyd and Walls, 1953) but the external sph...

Only a few papers have been published about unusual localisations of pressure ulcer. To date, no papers were published presenting pressure ulcer on external genitals in women. The paper presents the mechanism of origin of vulval pressure ulcer, surgical treatment (excision of lesion tissue of the pressure ulcer) and reconstruction of the vulva. The patient, aged 50, has been paraplegic for 20 y...

In order to achieve integrated condition in the girth welding of high pressure natural gas transmission pipelines, the weld zones and its surrounding area should have good mechanical properties. Residual stresses are an important defect especially in the girth welding of the pipeline. In this study, two API X70 steel pipes (with spiral seam weld) of 56 inches outside diameter and 0.780 inch wal...
