Geologic carbon storage is considered to be one of the main solutions to significantly reduce CO2 emissions to the atmosphere to mitigate climate change. CO2 injection in deep geological formations entails a twophase flow, being CO2 the non-wetting phase. One of the main concerns of geologic carbon storage is whether the overpressure induced by CO2 injection may compromise the caprock integrity...

Diastolic phase of cardiac function is associated with lower arterial flow and hence higher concentration of intra arterially injected drug is achieved at the site of injection. It is herein postulated that drugs show higher efficacy when injected during the diastolic phase of cardiac function. It is also postulated that this benefit cannot be achieved when the drug is injected with higher rate...

We developed a method for quantitatively determining theophylline in serum, using a heterogeneous immunoassay called flow-injection immunoanalysis. The reaction involves competition between serum theophylline and theophylline-labeled liposomes. Separation occurs on a solid-phase reactor column containing immobilized antibody to theophylline incorporated in a flow-injection system. Subsequent ly...

-In storm waterways and at dam outlets, high-velocity supercritical flows are characterized by substantial air bubble entrainment. The entrainment of fine air bubbles and the strong turbulent mixing contribute both to the air-water transfer of volatile gases (e.g. oxygen, nitrogen, VOC). The paper describes new experimental data obtained in a 25 m long channel with a 4 ° slope. The analysis of ...

A numerical study is conducted to investigate fluidic control for transonic flow over an open cavity. Numerical results are obtained for the unsteady threedimensional flow with different steady mass injection rates upstream of the cavity. The simulations use a hybrid two-equation turbulence model in the Detached Eddy Simulations (DES) to calculate the flow and acoustic fields. Computational res...

Regional Cerebral Blood Flow Measured by the Gamma Camera After Direct Injection of Xe into the Distal Stump of the Occluded Middle Cerebral Artery • Regional cerebral blood flow (rCBF) was measured after intracarotid injection of Xe concurrently with measurements of local cerebral blood flow (LCBF) after injection of Xe directly into the distal stump of the occluded middle cerebral artery (MCA...

objective(s): nucleus raphe magnus (nrm) that is involved in the regulation of body temperature contains nitric oxide (no) synthase. considering the effect of no on skin blood flow control, in this study, we assessed its thermoregulatory role within the raphe magnus. materials and methods: to this end, tail blood flow of male wistar rats was measured by laser doppler following the induction of ...

We investigate the hydromagnetic effect on viscous incompressible flow between two horizontal parallel porous flat plates with transverse sinusoidal injection of the fluid at the stationary plate and its corresponding removal by periodic suction through the plate in uniform motion. The flow becomes three dimensional due to this injection/suction velocity. Approximate solutions are obtained for ...

We numerically investigate the stability problem of the injection molding process. It was indicated by Bulters and Schepens Bulters and Schepens 2000 that surface defects of injection molded products may be attributed to a flow instability near the free surface during the filling stage of the mold. We examine the stability of this flow using the extended Pom–Pom constitutive equations. The mode...
