The mobilization of the trapped residual oil is an important part of Enhanced Oil Recovery. The desaturation of nonwetting fluids from porous media is often described using capillary numbers which are a ratio of viscous forces over the capillary forces between the wetting and the nonwetting fluids. Twodimensional microfluidic devices (micromodels) play an important role as they allow for the vi...

BACKGROUND/AIMS Nailfold capillaroscopy (NFC) has been used to examine morphological and functional microcirculation changes in connective tissue diseases. It has been demonstrated that NFC patterns reflect abnormal microvascular dynamics, which may play a role in fibromyalgia (FM) syndrome. The aim of this study was to determine NFC patterns in FM, and their association with clinical features ...

conclusions the early signs and symptoms of iscls may be subtle; therefore the diagnosis can easily be missed and prompt treatment of the syndrome may be postponed. thus, the clinician must consider iscls in differential diagnosis in cases of hypotension, hemoconcentration, and hypoalbuminemia. case presentation we present a 58-year-old female who presented with peripheral edema, leg pain, and ...

An increased ratio of muscle capillary to fiber number (capillary/fiber number) at altitude has been found in only a few investigations. The highly aerobic pectoralis muscle of finches living at 4,000-m altitude (Leucosticte arctoa; A) was recently shown to have a larger capillary/fiber number and greater contribution of tortuosity and branching to total capillary length than sea-level finches ...

asymptotically exact and nonlocal fourth order nonlinear evolution equations are derived for two coupled fourth order nonlinear evolution equations have been derived in deep water for two capillary-gravity wave packets propagating in the same direction in the presence of wind flowing over water.we have used a general method, based on zakharov integral equation.on the basis of these evolution eq...

Sequential nailfold capillary microscopy was carried out monthly for seven months in seven patients (four with scleroderma, one with dermatomyositis, one with mixed connective tissue disease, and one with limited connective tissue disease). Progressive enlargement of some capillary loops was observed, with a number becoming obliterated, leaving avascular areas. Extravasation from capillaries us...
