The fluid and cellular phases of inflammatory resonse have been measured using a technique employing subcutaneous implantation of polyurethane foam cubes impregnated with heat-killed Mycobacterium tuberculosis. Phenylbutazone, azathioprine, aspirin, cyclophosphamide, and prednisolone suppressed fluid response, whereas sodium aurothiomalate, hydroxychloroquine, and D-penicillamine had no effect....

Previously, we reported that fluid-phase endocytosis of native LDL by PMA-activated human monocytederived macrophages converted these macrophages into cholesterol-enriched foam cells (Kruth, H. S., Huang, W., Ishii, I., and Zhang, W. Y. (2002) J. Biol. Chem. 277, 34573-34580). Uptake of fluid by cells can occur either by micropinocytosis within vesicles (<0.1 microm diameter) or by macropinocyt...

A fluid has been demonstrated to flow from the trachea of fetal lambs1,2). By studies with the modified Wilhelmy balance the fluid has been found to have a very low surface tension when the surface area is compressed to 20% of its maximal size3). These findings are of particular interest since the fluid originates from the lungs and is aspirated with initial aeration. It is likely that the surf...

In this paper a numerical model to study the vibro-acoustic behavior of a laminated plate backed by a poroelastic foam layer is developed. Such approach consists on a coupled mitigation strategy aiming either mechanical vibration suppression or acoustic attenuation as well. The laminated plate model consists of fiber laminae with interleaved viscoelastic layers in standard constrained or integr...

Degranulated mast cells are present in human fatty streaks. Chymase in granules released from degranulated rat serosal mast cells, i.e., in granule remnants, proteolyzes human high density lipoprotein3 (HDL3), and so reduces its ability to induce cholesterol efflux from macrophage foam cells in vitro. In this study we found that remnant chymase, by proteolyzing human serum and human aortic inti...

drilling fluid is the most important lifeline of the drilling operation, that main task is facilitate the cuttings removal of the drilling. there are varieties of drilling fluids such as sodium bentonite based-drilling fluid is called “mud” and drilling foam or surfactant based-drilling fluid is called “soap”. the present work aims are study on the modified drilling mud properties by using the ...

Surfactant transport from foam film to is an essential (yet poorly understood) aspect of the viscoplastic yielding behaviour flowing foam. Recent experimental and modelling work by Bussonnière &amp; Cantat ( J. Fluid Mech. , vol. 922, 2021, A25) has, however, helped advance understanding relevant surfactant processes: significance that described herein.

Wet granulation using foaming binder solution is a new approach of liquid delivery to create granules. This study compares wet granulation via foamed binder addition method and sprayed binder addition method by studying the kinetics of foam and drop penetrations into loosely packed powder beds. Foam and drop nucleation kinetics were compared by examining specific penetration time (penetration t...

We describe the design of an interactive rendering system for particle-based fluid simulations comprising hundreds of millions of particles per time step. We present a novel binary voxel representation for particle positions in combination with random jitter to drastically reduce memory and bandwidth requirements. To avoid a time-consuming preprocess and restrict the workload to what is seen, t...
