Lumbar cerebrospinal fluid pressure waves versus intracranial pressure waves in idiopathic normal pressure hydrocephalus

British Journal of Neurosurgery, 2006
The aim of this study was to explore how the lumbar cerebrospinal fluid pressure (CSFP) waves recorded during lumbar infusion compared with the intracranial pressure (ICP) waves recorded, either during lumbar infusion or during long-term, overnight monitoring.

On the pressure of gravitational waves

General Relativity and Gravitation, 2006
A system of coupled point masses under the influence of gravitational waves is considered. By means of the geodesic deviation equation as the equation of motion it is shown, taking into account the second order small terms, that there exist forces which cause the acceleration of the system in the longitudinal direction. The longitudinal force is due to

Pressure wave transducing

The Journal of the Acoustical Society of America, 1987
A loudspeaker driver has its front surface adjacent one end of a low loss acoustic waveguide and its rear surface adjacent to one end of a second acoustic waveguide that is one third the length of the first. The other openings of the waveguides face air and couple acoustical energy substantially uniformly over a relatively broad range of frequencies ...

On pressure waves in a layered liquid

Applied Scientific Research, 1963
The propagation of pressure waves in a two-layered liquid medium (assumed to be compressible) resting on a rigid bottom has been considered. The source of disturbance has been taken to be three-dimensional with spherical symmetry. Similar problems of layered but semi-infinite liquids have been discussed by Pekeris, Press and Ewing (cf Ewing, Jardetzky ...

PRESSURE WAVES IN SO-CALLED LOW-PRESSURE HYDROCEPHALUS

The Lancet, 1972
Abstract Episodes of raised intracranial pressure were discovered in patients who were thought to have low-pressure hydrocephalus. Possibly these episodes identify patients in whom continuing deterioration may be expected, and the long-term measurement of intracranial pressure in such patients may be valuable in deciding which of them should have a ...

Relationship between terminal ileal pressure waves and propagating proximal colonic pressure waves

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1999
The relationship between propagating distal ileal and proximal colonic motor patterns has not been systematically examined in humans. Our aim was to define the relationships, if any, between prolonged propagating contractions or discrete clustered contractions and cecal propagating sequences using multiple manometric recording sites spanning the distal
