A method for generating three-dimensional, time-dependent turbulent inflow data for simulations of complex spatially developing boundary layers is described. The approach is to extract instantaneous planes of velocity data from an auxiliary simulation of a zero pressure gradient boundary layer. The auxiliary simulation is also spatially developing, but generates its own inflow conditions throug...

We present results from axisymmetric, time-dependent magnetohydrodynamical (MHD) simulations of a gaseous envelope collapsing onto a black hole (BH). We consider gas with so small angular momentum that, if not for the effects of MHD, the flow would accrete directly onto a BH. We find that after an initial transient, the flow settles into a configuration with four components: (i) a radial equato...

Two methods of measuring stroke volume and cardiac output with pulsed Doppler twodimensional echocardiography were developed and validated against the thermodilution technique in 39 patients, 33 of which were in an intensive care unit. With the use of the apical four-chamber view, a mitral inflow method combined the velocity of left ventricular inflow at the mitral anulus with the crosssectiona...

We show that outflow rates in jets directly depend on the spectral states of black holes. In particular, in soft states, when the Comptonized electrons are cold, outflow rate is close to zero. In hard states, outflow could be steady, but the rate may be very small – only a few percent of the inflow. In the intermediate states, on the other hand, the outflow rate is the highest – roughly thirty ...

A51-year-old woman was referred for evaluation of an asymptomatic systolic murmur. Transthoracic echocardiography showed a large right atrial (RA) mass with intermittent prolapse through the tricuspid valve and extending into the pulmonary artery. On the preoperative transesophageal echocardiographic examination, a tumor with multiple strands was seen. One strand intermittently obstructed the o...

Where V is the volume of the tank [m3], Qin & Qe are respectively the inflow rate and outflow rate [m3d-1]; CT,in & CT are concentrations in the inflow and outflow, respectively [g m-3]; krem , ksed , kbiodeg and kvol are the overall pseudo first order in-stream removal, sedimentation, biodegradation and volitalization rate constants, respectively [d-1] ; Sexternal is the external source due to...

We report on a rare case of blunt traumatic hepatic arteriovenous fistula arising from a pseudoaneurysm in a 35-year-old woman. Transarterial embolization was performed with n-butyl-2-cyanoacrylate, under inflow control with loose coil packing within the pseudoaneurysm and outflow control by balloon occlusion of the hepatic vein. A promising therapeutic outcome was achieved without any serious ...

Ventilation in resting, unrestrained Boa constrictor, Python regius and Thanmophis s. sirtalis was monitored using various combinations of a closed Kopfkappe (head chamber), intratracheal pressure catheters, strain gauges around the trunk, and a flow meter connected to one of the nostrils. Records of intratracheal pressure with and without closing the Kopfkappe show that the latter device induc...

BACKGROUND The origin and magnitude of the back pressure opposing diastolic coronary inflow remain controversial. The arterial pressure at which coronary inflow stops during a prolonged diastole, ie, "zero-flow pressure," is higher than coronary venous pressure. However, because of capacitive discharge as distending pressure falls, flow at the microcirculatory level exceeds inflow, and coronary...
