Static anisotropic elastic properties of the aorta in living dogs.
Static anisotropic elasticity was studied in the middle descending thoracic aorta of 14 living dogs. Special transducers were used to measure radius and longitudinal stress at several pressures in situ in an isolated vessel segment. From these data, moduli describing elastic properties of the vessel wall were calculated. Results indicate that (1) at a physiologic pressure of 154 cm H2O (extensi...
متن کاملDynamic anisotropic viscoelastic properties of the aorta in living dogs.
The purpose of this paper is to describe the incremental dynamic anisotropic viscoelastic properties of the middle descending thoracic aorta in ten living dogs. A segment of the middJe descending thoracic aorta was isolated in situ and connected to a reservoir filled with oxygenated blood. The height of the reservoir could be adjusted to impress a known pressure on the segment. In addition, a s...
متن کاملAnisotropic elastic properties of microtubules.
We review and model the experimental parameters which characterize elastic properties of microtubules. Three macroscopic estimates are made of the anisotropic elastic moduli, accounting for the molecular forces between tubulin dimers: for a longitudinal compression of a microtubule, for a lateral force and for a shearing force. These estimates reflect the anisotropies in these parameters observ...
متن کاملStatic elastic properties of the left coronary circumflex artery and the common carotid artery in dogs.
Static elastic properties were studied in isolated segments of the left coronary circumflex artery (LCCA) and the right common carotid artery (CA) from 14 dogs at in-vivo values of pressure and length. A microscope with a Filar micrometer was used to measure radius and length. From these data it was possible to study the pressure-radius relationship and compute various anisotropic elastic modul...
متن کاملElastic Properties of Sedimentary Anisotropic Rocks
In multidisciplinary studies carried out in the Budare Oil Field of the Great Oficina Oil Field, there was difficulty matching well log synthetic seismograms with 2D and 3D seismic data. In addition, the seismically determined depths of reservoir horizons are greater than the well sonic log depths. To examine this discrepancy we conducted an experimental study of dynamic elastic parameters of t...
