1. Experiments on dogs show that whereas the pulse pressure in the larger arteries (femoral) varies extensively, it varies within narrow limits only in the small ones (dorsal artery of the foot). These results supply an experimental explanation for the fact that in man uniform pressure readings were obtained by Gaertner's method at the digital artery. 2. The experiments show likewise that in ce...

In this paper the effect of composite hoop-wrapped on stress intensity factor for semi-elliptical external crack which located in spherical pressure vessel, were investigated through the Finite Element Analysis. In order to find the effect of some parameters such as composite thickness and width, internal pressure and crack geometry, comparisons between different cases were done and discussed i...

OBJECTIVE To evaluate the effect of a single cystoscopic injection of botulinum toxin to the external urethral sphincter in treating detrusor external sphincter dyssynergia. DESIGN An open treatment trial with pre- and post-treatment evaluations. SUBJECTS A total of 20 suprasacral spinal cord injured patients with pure detrusor external sphincter dyssynergia. METHODS A single dose of 100 ...

The genesis of gallop sounds was investigated in 12 patients by simultaneous measurement of external apexcardiographic (ACG) and left ventricular (LV) pressure, dP/dt, and sound using infinite time constant piezo-resistive pressure transducers with identical sensitivity and frequency responses. Absolute intensity of internal and external sound was quantified. The external transducer was applied...
