A new model for blood flow in capillaries
Blood circulation in small vessels has been the subject of a very large literature, starting with the fundamental studies by Poiseuille [15], followed by Murray [13], Landis [9], F̊ahraeus [2], F̊ahraeus -Lindqvist [3], Krogh [8] and others. Very soon it was clear that blood rheology is very sensitive to the size of the vessel, exhibiting some counter-intuitive behavior when the vessel diameter r...
متن کاملNew Design of Capillaries for Multi-Tier Wire Bonding
The demand for increased computing power and more complex integrated circuit devices with increased functions per chip results in high lead-count integrated circuit packages. With the shrinkage in integrated circuit sizes towards smaller packages, and the decrease in pad pitch, the trend is moving from the current ultra-fine-pitch volume production of 50 μm to even lower pad pitches. However, t...
متن کاملIntestinal Capillaries
Horseradish peroxidase (mol. diam. approximately 50 A) and ferritin (mol. diam. approximately 110 A) were used as probe molecules for the small and large pore system, respectively, in blood capillaries of the intestinal mucosa of the mouse. Peroxidase distribution was followed in time, after intravenous injection, by applying the Graham-Karnovsky histochemical procedure to aldehyde-fixed specim...
متن کاملRutin for the Capillaries
T« .HE PRINCIPAL effect of rutin when taken into the body is to restore the strength of the capillary walls when they become weakened. Rutin is a new, cheap, nonpoisonous drug that comes from buckwheat, tobacco, yellow pansies, and at least 35 other plants. Extensive clinical studies of its use in various disease conditions associated with hemorrhage or weak capillaries have demonstrated the va...
متن کاملFragility of pulmonary capillaries.
Although the pulmonary capillaries were discovered in 1661, the ultrastructure of the wall was not elucidated until 60 years ago. Electron micrographs then showed that only 0.2 μm of tissue separated the capillary endothelium from the alveolar space over much of the area. In retrospect this vanishingly small protective layer should have alerted physiologists to the potential fragility of the ca...
