We studied nine young adult beagles at rest and during four levels of dynamic exercise before and after electrolytic lesions were made in the hypothalamus in the region of the fields of Forel. The beagles were habituated to run freely on a motor-driven treadmill and were instrumented chronically to allow repeated measurement of cardiovascular variables.(More)
Five different experiments were conducted to determine if estimated liver plasma flow and/or plasma volume were changed as a result of exposure to 2.8 atmospheres absolute (ATA) while breathing 100% oxygen or 6 ATA while breathing compressed air. The experiments were designed to separate the relative roles of the ambient pressure, the partial pressure of(More)
Segments of the canine ascending aorta, upper descending thoracic aorta, and middle descending thoracic aorta were instrumented with ultrasonic dimension gauges and a cathetertip manometer simultaneously to measure changes in segment diameter, length, and intravascular pressure. Volume distensibility (EV) was calculated as the sum of circumferential(More)
Data are presented which demonstrate no correlation between atrial electrical activity and diameter changes in the descending thoracic aorta of dogs or rabbits. The experiments conducted included bypassing a segment of the descending thoracic aorta in dogs, and production of a variety of arrhythmias without the bypass in dogs and rabbits. We found no(More)
We characterized the in vivo mechanical properties of segments of upper descending thoracic aorta (UDTA) in terms of volume distensibility, which was derived from measurements of pulsatile intravascular pressure, inner wall radius, and length changes. Data for this analysis were obtained from six dogs at rest and during moderate treadmill exercise (8%(More)
Forty-one individuals from Rurutu Island (Austral Archipelagos) and 41 individuals from the Gambier Archipelagos have been typed for HLA; for blood groups ABO, Rh, MNSs, P, Kell, Kp, Lewis, Lutheran, Kidd; for the electrophoretic systems G6PD, 6-PGD, PGM1, PGM2, AcP, ADA, GPT, Est-D, GLO I, and for the immunoglobulin allotypes Gm and Km. There is a high(More)
Most timber bridges in the Province of Manitoba are constructed with sawn Douglas Fir stringers, which are simply-supported with spans ranging from 6 to 10 m. Due to an increase in the allowable gross vehicle weight, most of these bridge stringers may require flexural and/or shear strengthening to increase their load-carrying capacity.
