High Frequency Surface Heat Flux Imaging of Bypass Transition

Volume 4: Turbo Expo 2004, 2004
A high-frequency surface heat flux imaging technique was used to investigate bypass transition induced by freestream turbulence. Fundamental experiments were carried out at the University of Oxford using high-density thin film arrays on a flat plate wind tunnel model.

Modulation of Platelet Surface Adhesion Receptors during Cardiopulmonary Bypass

Anesthesiology, 1991
Alterations in platelet receptors critical to adhesion may play a role in the pathogenesis of the qualitative platelet defect associated with cardiopulmonary bypass. Using flow cytometry, we measured changes in the following platelet surface adhesive proteins: the von Willebrand factor receptor, glycoprotein Ib; the fibrinogen receptor, glycoprotein ...

Root Surface Caries: A Complication of the Jejunoileal Bypass

Obesity Surgery, 2000
A patient developed root surface caries and loss of teeth following the jejunoileal (JI) bypass. We attempted to confirm the association of root surface caries with the JI bypass and explore the mechanisms by which it occurs.The number of root surface caries per year after, and an equal period of time before, a JI bypass was determined in 18 patients ...

The influence of compliant surfaces on bypass transition

Experiments in Fluids, 2007
The objective of the work was to investigate the effect of compliant surfaces on the receptivity and bypass transition of a boundary layer. Hot wire measurements in the pre-transitional and transitional boundary layers on nine different compliant and one rigid surface with identical geometries were made.

Blood - Artificial Surface Interactions during Cardiopulmonary Bypass

The International Journal of Artificial Organs, 1990
Evaluation of the biocompatibility of four different types of oxygenator (bubble, membrane, hollow fibre and ‘hybrid’) was performed on 26 patients undergoing cardiopulmonary bypass during elective coronary surgery. More platelet derangement and an increased degree of hemolysis, revealed by higher plasmatic concentration of beta-thromboglobulin ...

Blood-Surface Interactions During Cardiopulmonary Bypass

Journal of Cardiac Surgery, 1993
The interaction between blood and the synthetic surfaces of the heart-lung machine activates plasma protein systems and blood cells to produce a host of vasoactive substances that mediate the "whole body inflammatory response" associated with cardiopulmonary bypass (CPB). Plasma proteins are instantaneously adsorbed onto nonendothelial surfaces; plasma
