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 ...

where Pn and Pw are the average pressures of nonwetting and wetting phases, respectively; Pc is capillary pressure, Capillary pressure plays a central role in the description of water and S is the wetting phase saturation. A schematic depicflow in unsaturated soils. While capillarity is ubiquitous in unsaturated tion of Pc vs. S curves is given in Fig. 1. analyses, the theoretical basis and pra...

Fast synchrotron-basedX-raymicrotomographywas used to image the injection of super-critical CO2 under subsurface conditions into a brine-saturated carbonate sample at the pore-scale with a voxel size of 3.64μm and a temporal resolution of 45s. Capillary pressure wasmeasured from the images by finding the curvature of terminal menisci of both connected and disconnected CO2 clusters. We provide a...

OBJECTIVES To develop a technique for automatic inflation of a percutaneous transluminal coronary angioplasty (PTCA) balloon, with continuous measurement of the balloon pressure and volume; to validate the technique for determining the mechanical characteristics of coronary arteries. METHODS During necropsy examination of the hearts of nine patients, 17 coronary artery samples were obtained f...

Klippel-Trenaunay syndrome (KTS) is a rare complex malformation characterized by the clinical triad of capillary malformations, soft tissue and bone hypertrophy, and venous/lymphatic malformation. Fractures of long bones in such cases are challenging to treat. A 12-year-old female with this syndrome presented with femoral shaft fracture of right thigh. She was initially kept on skeletal tractio...

Extrapolation from post-exercise measurements has been used to estimate respiratory and blood gas parameters during exercise. This may not be accurate in exercise with reduced breathing frequency (RBF), since spontaneous breathing usually follows exercise. This study was performed to ascertain whether measurement of oxygen saturation and blood gases immediately after exercise accurately reflect...

A burn case of 42-year-old female patient due to pressure cooker explosion associated with mandibular fracture is presented. After early tangential excision of the deep second- and third-degree-burn areas, a split-thickness skin grafting was applied. Open reduction and internal fixation therapy with miniplate system were done for linear symphysis fracture. As much as we know, there was no repor...

partment pressures that exceed capillary perfusion, causing ischemia and edema within the compartment. This has been well characterized in the lower leg following excessive muscle strain, tibia fracture, or other blunt trauma and in the forearm following blunt trauma. There are few reports of dorsal compartment syndrome of the upper arm. A literature review found only one previous case without ...

We use an harmonic technique to probe the dynamics of a liquid-liquid interface in a capillary. The capillary pressure drop induced by a harmonic displacement of the fluids is recorded as a function of the excitation amplitude and frequency. At low frequency there is an amplitude threshold above which the contact line depins and slides, and this threshold is related to the static hysteresis of ...
