Effect of Low Dialysate Flow Rate on Hemodialyzer Mass Transfer Area Coefficients for Urea and Creatinine.
Recent work has shown that the dialyzer mass transfer area coefficient (Ko A) for urea increases when the dialysate flow rate is increased from 500 to 800 mL/min. In this study we determined urea and creatinine clearances for two commercial dialyzers containing polysulfone hollow fibers in vitro at 37°C, a nominal blood flow rate of 300 mL/ min, and dialysate flow rates (Qd ) ranging from 100 t...
متن کاملMicro Counter-current Flow System for Highly Efficient Extraction
We demonstrated micro counter-current flow in a glass microchip utilizing surface modification patterning method to control surface tension. In order to visualize the micro counter-current flow, fluorescent microparticle dispersion solutions were observed by fluorescence microscopy. When the flow volume ratio of water and organic solution was changed, the switching point of flow direction was o...
متن کاملComparison of Co-Current and Counter-Current Flow Fields on Extraction Performance in Micro-Channels
Several applications such as liquid-liquid extraction in micro-fluidic devices are concerned with the flow of two immiscible liquid phases. The commonly observed flow regimes in these systems are slug-flow and stratified flow. The latter regime in micro-channels has the inherent advantage that separation of the two liquids at the exit is efficient. Recently extraction in a stratified counter-cu...
متن کاملEOS imaging versus current radiography: A health technology as-sessment study
Background: EOS is a 2D/3D muscle skeletal diagnostic imaging system. The device has been developed to produce a high quality 2D, full body radiographs in standing, sitting and squatting positions. Three dimensional images can be reconstructed via sterEOS software. This Health Technology Assessment study aimed to investigate efficacy, effectiveness and cost-effectiveness of new emerged EOS imag...
متن کاملFlow velocity profile of micro counter-current flows.
Flow velocity profiles of micro counter-current flow of aqueous and butylacetate phases in a microchannel having a width of 100 microm were measured by micro particle image velocimetry. In order to analyze the hydrodynamic characteristics of the counter-current flow, we derived a simple analytical model for the velocity profile. When flow rates of the aqueous and organic phases were 0.2 and 0.1...
