Damping of Sound on the Chest Surface.

• A number of investigators" have recently studied liow heart sounds and murmurs spread through the various tissues of men and dogs. For instance, Magri et al. studied the transmission of heart sounds over the surface of the exposed human heart. Ken and Harp, Iverr et al. and ourselves"' investigated the velocity and the damping with which sound is transmitted through arteries, and showed that ...

The sound damping constant for generalized theories of gravity

The near-horizon metric for a black brane in Anti-de Sitter (AdS) space and the metric near the AdS boundary both exhibit hydrodynamic behavior. We demonstrate the equivalence of this pair of hydrodynamic systems for the sound mode of a conformal theory. This is first established for Einstein’s gravity, but we then show how the sound damping constant will be modified, from its Einstein form, fo...

Morphology-property relationships in wood-fibre-based polyurethanes

Many of the advances in material performance over the last decade can be attributed to developments in multicomponent polymer systems and specifically, to multiphase materials such as incompatible polymer blends and fibre-reinforced composites. In these types of material, performance properties are often dominated by the interphase that defines the transition region from one pure phase to anoth...
