The flow field is the fluid dynamic path in strongly heterogeneous reservoirs, and its evolution significantly affects distribution of remaining oil, showing a disordered highly dispersed mode caused by long-time water injection. By combining traditional flow-field evaluation with diagnostics, this paper proposes methodology to quantitatively characterize adjust real time during late stage wate...

This paper presents an effective numerical simulation method for production prediction of in situ recovery oil shale reservoirs with steam injection. In this method, finite volume-based discretization schemes heat and mass transfer equations the thermal compositional model are derived used. The embedded discrete fracture is used to accurately handle fractured vertical well. A smooth non-linear ...

Light and electron microscopic methods were used to examine the neurons in the monkey cerebral cortex labeled autoradiographically following the uptake and transport of [3H]-gamma-aminobutyric acid (GABA). Nonpyramidal cell somata in the sensory-motor areas and primary visual area (area 17) were labeled close to the injection site and at distances of 1 to 1.5 mm beyond the injection site, indic...

Intraperitoneal injection of virulent infectious pancreatic necrosis virus (IPNV) into yearling brook trout Salvelinus fontinalis induced an asynlptomatic, chronic w u s infection that persisted for at least 76 wk post-lnlection (wpl) in spite of the production of a strong humoral immune response. At 8 wpi, 100 % of the fish in one of the injected groups were IPNV camers , as determined by orga...

We report on a polarization modulation in vertical cavity surface emitting lasers (VCSEL), based on RF electrical injection. Complex polarization dynamics in the single mode regime is studied as a function of RF frequency and power at different bias currents. It has been observed that the polarization state of the VCSEL can be altered by changing the frequency of RF current modulation. Time res...

To the Editor:—We read with interest the recent report by Martinez et al. regarding a combined infraclavicular plexus blockade with suprascapular nerve block for humeral head surgery in a patient with severe respiratory failure. However, we have some concerns with regard to the following points: First, it is not clearly stated whether the authors performed an infraclavicular plexus block using ...

Experiments have examined the phenomenon of direct contact condensation when steam is injected vertically into subcooled water pool. The investigation carried out by varying mass flow rate and submergence depth injection pipe in range 10–50 kg/h 1–13 cm, respectively. behavior bubble that appeared at outlet, transient heat transfer coefficient, pressure variation pipe, its associated frequency ...

Neurons in the Y group of the vestibular nuclei are activated disynaptically from the ipsilateral VIIIth nerve and polysynaptically from the contralateral nerve. The ipsilateral anterior and posterior semicircular canals project to the Y group via interneurons in the vestibular nuclei. Candidate interneurons located in the rostrolateral corner of the superior (SVN) and in the caudal medial (MVN...

The intraretinal path taken by fibers of the arcuate bundle was studied in four Rhesus monkeys. The fibers incorporated radioactivity subsequent to the injection of a small amount of Hproline into the retina. The classical arciform projection was described and it was noted that near the disc, where the nerve-fiber layer contained many unlabeled fibers from the region of the area centralis, the ...

The gas-lift technique comprises the injection of gas bubbles in vertical oil wells to increase production. It is based on a reduction of the tubing gravitational pressure gradient. Several fluid-flow phenomena influencing such vertical gas-liquid flows are discussed. These effects include the radial distribution of void fraction and of gas and liquid velocity, flow regime changes, and system s...
