The spleen acts as an erythrocyte reservoir in highly aerobic species such as the dog and horse. Sympathetic-mediated splenic contraction during exercise reversibly enhances convective O2 transport by increasing hematocrit, blood volume, and O2-carrying capacity. Based on theoretical interactions between erythrocytes and capillary membrane (Hsia CCW, Johnson RL Jr, and Shah D. J Appl Physiol 86...
Aquaporin-1 (AQP1) water channels are expressed widely in epithelia and capillary endothelia involved in fluid transport. To test whether AQP1 facilitates water movement from capillaries into the peritoneal cavity, osmotically induced water transport rates were compared in AQP1 knockout [(-/-)], heterozygous [(+/-)], and wild-type [(+/+)] mice. In (+/+) mice, RT-PCR showed detectable transcript...
derived from [3], inside the target gas for the pumping laser. In the case of a capillary tube, the boundary conditions at the capillary wall are numerically implemented as described in [4]. The parameters entering the functions Modelling of transport and amplification of a short XUV pulse in a plasma with high gain G. Maynard, B. Cros, G. Vieux, A. Lenglet, S. Sebban, I. Bettaibi T. Mocek , J....
Capillary-driven micro flow allows liquid transport by interfacial force without external pressure or momentum. Theoretical and experimental studies have been conducted to predict the movement of the flow meniscus in the application of capillary underfill flows. In a flip chip package, two-dimensional motions of flow front through solder bumps can result in unwanted air void formation because t...
Plants and insects use slender conical structures to transport collect small droplets, which are propelled along the due capillary action. These droplets can deposit a fluid film during their motion, but despite its importance many biological systems industrial applications properties of deposited unknown. We characterise deposition by developing an asymptotic analysis together with experimenta...
Hsia, Connie C. W., Robert L. Johnson, Jr., and Dipen Shah. Red cell distribution and the recruitment of pulmonary diffusing capacity. J. Appl. Physiol. 86(5): 1460–1467, 1999.—The distribution of red blood cells in alveolar capillaries is typically nonuniform, as shown by intravital microscopy and in alveolar tissue fixed in situ. To determine the effects of red cell distribution on pulmonary ...
The magnitude of changes in luminal hydrostatic pressure (DeltaP(L)), peritubular capillary hydrostatic pressure (DeltaP(PT)), and peritubular capillary colloid osmotic pressure (Deltapi) was determined in the Necturus kidney during volume expansion (VE). The specific effects of separate changes of each pressure parameter on proximal net sodium transport (J(Na)) were studied in isolated perfuse...
The migration of liquids in porous media, such as sand, has been commonly considered at high saturation levels with liquid pathways at pore dimensions. In this Letter, we reveal a low saturation regime observed in our experiments with droplets of extremely low volatility liquids deposited on sand. In this regime, the liquid is mostly found within the grain surface roughness and in the capillary...
Ž Abstract: In this study, silica-based packing materials with pore sizes herein ̊ . referred to primarily as channel diameters, d ranging from 60 to 4000 A were ch utilized to elucidate the role of pore size in CEC. Separations were conducted using a commercially available CE system, the inlet and outlet buffer reservoir compartments having been modified to allow constant application of ;150 ps...
A fundamental 2-D model was developed to predict the heat and mass transfer that occur during the frying and cooling process of tortilla chips. Semi-empirical correlations were included to account for structural changes, such as shrinkage and expansion due to puffing. All water present in the tortilla chip was considered bound and led to shrinkage when removed. The parameters that were studied ...
