The flux of platelet agonists into flowing blood is a critical event in thrombosis and hemostasis. However, few in vitro methods exist for examining and controlling the role of platelet agonists on clot formation and stability under hemodynamic conditions. In this project, we fabricated a membrane-based method for introducing a solute into flowing blood at a defined flux [1]. The device consist...

[1] We have discovered a prominent >190 km long, 0.5– 6 km wide lava channel on Io. The channel is sinuous with interior islands andmay be associatedwith the active Tawhaki Patera hotspot. Photoclinometric analysis of the Galileo images indicates that this channel, provisionally named Tawhaki Vallis, is 40 – 65 m deep. Although a constructional contribution cannot be ruled out, the depth, morph...

The dissolution rates of cholesterol in model bile salt solutions are controlled by diffusion in slowly flowing bile and by interfacial kinetics in rapidly flowing bile. At low flow, dissolution varies with the square root of bile flow and can be predicted, a priori, from existing correlations of mass transfer. At high bile flow, dissolution is independent of bile flow and is probably dominated...

BACKGROUND Estimation of the quantity of colostral IgG or serum IgG absorbed following ingestion of colostrum by calves is essential for monitoring the effectiveness of colostrum feeding practices on dairy farms. Milk total solids concentrations determination is a critical part of quality assessment of nonsaleable whole milk prior to feeding to calves. To date, on-farm methods to assess colostr...

The underlying objective of the present study is to increase gas-solids contact in a circulating fluidized bed by the introduction of obstacles in the riser portion. The presence of such obstacles leads to suppression of radial inhomogeneities in the solids mass flux and concentration, and break-up of solids clusters. At ambient conditions, gas-solids mass transfer was investigated for cocurren...

BACKGROUND Working at high solids (substrate) concentrations is advantageous in enzymatic conversion of lignocellulosic biomass as it increases product concentrations and plant productivity while lowering energy and water input. However, for a number of lignocellulosic substrates it has been shown that at increasing substrate concentration, the corresponding yield decreases in a fashion which c...

Thiocyanate (SCN- ) is a toxic compound that forms when cyanide (CN- ), used to recover gold, reacts with sulfur species. SCN- -degrading microbial communities have been studied, using bioreactors fed synthetic wastewater. The inclusion of suspended solids in the form of mineral tailings, during the development of the acclimatized microbial consortium, led to the selection of an active plankton...

The flow-ability of granular is important parameter to be considered in many solids handling processes and operations such as transportation and storage. Flow property of granular solids depends on many factors of the physical properties such as the particle size distribution, the roughness of its surface, the content of moisture in solids and the relative humidity and temperature in its surrou...

Mathematical concepts of multivariate parametric solids, their description by a B-spline basis functions are discussed. Parametric solids can model both the shape and unisotropic interior. Three types of parametric solids i.e. Coons body 0, 1 and 2 are used to demonstrate the interior modelling often used as initial or boundary conditions in numerical simulation. Multiple parametric solids elem...
