Gravity drainage is the main mechanism which controls the oil recovery from fractured reservoirs in both gas-cap drive and gas injection processes. The liquid bridge formed between two adjacent matrix blocks is responsible for capillary continuity phenomenon. The accurate determination of gas-liquid interface profile of liquid bridge is crucial to predict fracture capillary pressure precisely. ...

Various indices of capillary supply to the rat heart were studied in neonatal rats injected for 2 or 4 weeks with protamine sulfate in saline (subcutaneously, 60 mg/kg body weight, 2 times/day). Cardiac capillarization was evaluated not only by traditional indices for the capillary supply, such as mean capillary density and myocyte-to-capillary ratio, but also by a more advanced morphometric me...

INTRODUCTION Blood samples are a critical component of Point-of-Care clinical diagnosis [1]. These blood samples are analyzed in Lab-on-a-Chip devices, which monitor important parameters such as glucose and lactate levels. For these systems to work, the blood sample must be introduced to an empty capillary microchannel that guides the sample to an on-chip sensor. Thus the filling characteristic...

Surface waves on fluids with wavelengths in the millimeter range are known as capillary waves. Surface tension determines the propagation and dispersion of capillary waves while gravity plays a minor role. We describe a simple method for generating standing capillary waves of known frequency on water and introduce a novel noncontact technique based on laser interferometry to measure the wavelen...

In an attempt to understand more fully the hemodynamic effects in mitral stenosis, the vascular response to effort was studied in 12 cases. It was found that pulmonary arterial pressures rose, but did not necessarily parallel changes in the pulmonary "capillary venous" pressure (pcv), suggesting that the response pattern may be modified by secondary pulmonary vascular change. Further, in some s...

The early extraction method of measuring capillary permeability was evaluated with theoretical models of capillaries and organs. The organs consisted of feeder lines and a capillary bed that was either homogeneous or heterogeneous with respect to capillary length or flow. The capillary permeability of the model organ determined by the early extraction method was compared with the actual permeab...
