The abdominal vegetative nervous system was studied in Walter Reed strain guinea pigs with experimental diarrhea produced by the method of Kalas. During the diarrheal phase, the regional abdominal sympathetic ganglia are normal, but after approximately 72...

The analysis and the design of a solar array drive mechanism (SADM) experimental model are presented. Emphasis is put on the design aspects relative to SADM drive and bearing units, although almost every component present in a space mechanism is described...

An experimental device to measure the abdominal pressure in child-size Anthropomorphic Test Dummies (ATDs) during dynamic tests was developed. A description is provided of the two ATDs in which the device was installed, the CRABI six-month-old and the CAM...

This study was conducted to determine if use of progressive muscle relaxation could decrease pain perception, analgesic use, and anxiety in post-operative abdominal surgery patients. Review of demographic data showed the experimental and control group to ...

Typical automotive related abdominal injuries occur due to contact with the rim of the steering wheel, seatbelt and armrest, however, the rate is less than in other body regions. When solid abdominal organs, such as the liver, kidneys and spleen are involved, the injury severity tends to be higher. Although sled and pendulum impact tests have been ...

Experimental data and results of SAIL model supported a study relating the spectral reflectance of wheat canopies (Triticum aestivum, L.) to their biophysical parameters which included an evaluation of the model potential for investigating such relationsh...

We propose a method to extract an abdominal aorta wall from an M-mode image. Furthermore, we propose the use of a Gaussian filter in order to improve image quality. The experimental results show that the Gaussian filter is effective in the abdominal aorta wall extraction.

Despite being a leading cause of death in the West, the pathophysiology of abdominal aortic aneurysms (AAA) is still incompletely understood. Pharmacotherapy to reduce the growth of small AAAs is limited and techniques for repairing aneurysms continue to evolve. Experimental models play a key role in AAA research, as they allow a detailed evaluation of the ...

Indium-111 chloride was administered intravenously for the scintigraphic demonstration of experimental abdominal wall abscesses in rabbits. Scintiscans performed 24 hr after injection of the isotope demonstrated reproducible localization of the abscesses....

The pressure of the portal trunk, the left gastric vein, the left and right gastroepiploic venins, the mesenteric vein and the abdominal aorta was measured experimentally at the same time in 10 normal dogs. The level of the raised pressure in the differen...

An evaluation of two experimental spinal orthoses was made for patients with chronic low back pain from data gathered from 34 subjects undergoing treatment at 4 hospital centers. Both the Lumbosacral Orthosis with Inflatable Pads (to increase abdominal pr...

The material properties of meshes used in hernia surgery contribute to the overall mechanical behaviour of the repaired abdominal wall. The mechanical response of a surgical mesh has to be defined since the haphazard orientation of an anisotropic mesh can lead to inconsistent surgical outcomes. This study was designed to characterize the mechanical behaviour of three surgical ...

�Atherosclerotic� abdominal aortic aneurysms (AAAs) occur with the greatest frequency in the distal aorta. The unique hemodynamic environment of this area predisposes it to site-specific degenerative changes. In this review, we summarize the differential hemodynamic influences present along the length of the abdominal aorta, and demonstrate how ...
