AUTHOR'S SYNOPSIS A model of the left ventricle was built incorporating a mitral and an
aortic valve. The bicuspid mitral valve was seen to achieve most of its closure during …

High-velocity powder injection is a promising new drag-delivery technique that provides
needle-and pain-free delivery of traditional drags, drags from biotechnology such as …

The closure mechanism of the human aortic valve is investigated experimentally with a rigid-
walled model placed in a pulsatile water-tunnel. It is shown that the valve is controlled by a …

THE human aortic valve consists of three cusps made of relatively inelastic, muscle-free
material about 0.15 mm thick. It opens and shuts about once a second, and withstands a …

The application of a heated thin metallic film to the measurement of mean skin friction in
laminar and turbulent flow on a flat plate, circular cylinder and in an annular tunnel is …

METHODS Three series of experiments were undertaken. In the first, partial veno-venous
bypass in adult pigs was undertaken using one catheter through the external jugular vein …

Observations of flow in furrowed channels support the calculations of part 1 (Sobey 1980). If
the mainstream flow is steady there is a critical Reynolds number below which separation …

ANATOMICAL studies have demonstrated the lateral extent of the sinus of Valsalva which
has a well defined ridge forming its upper margin, and have indicated that the geometry of …

Transdermal powdered drug delivery involves the propulsion of solid drug particles into the
skin by means of high-speed gas-particle flow. The fluid dynamics of this technology have …
