Results: Immediately after balloon dilation, the pressure gradient
across the pulmonary valve decreased from 73.
As depicted in Figure 6 the maximum value of the pressure gradient
is incremented with 1 bar/[degrees]CA in the range from 1.
The pressure gradient
in the melt film will be different from the pressure gradient
in the melt pool, as shown in Fig.
This can be understood in terms of the relative importance of the wind and ocean current drag terms compared with the Coriolis and pressure gradient
In these cross sections, the longitudinal pressure gradient
near the bed in the direction of the internal bend overcomes centrifugal force, and water near the bed is driven towards internal bend.
Separation prior to mass spectrometric measurements requires high performance liquid chromatography, which is binary, contains a degassing unit, low pressure gradient
unit, automatic sample dispenser, column thermostat, diode array and refractive index detectors.
5mmHg; this maintains a pressure gradient
that is higher within the eye compared to posteriorly, so allowing blood to flow down the pressure gradient
, that is to say, out of the eye via the central retinal vein.
According to the company, down hole pressure measurements and fluid samples suggest that the main oil reservoir is on the same static pressure gradient
as the Etom-2 well, which demonstrates that a major part of the Greater Etom structure is oil-filled.
All patients undergoing the procedure had severe aortic valve stenosis with the mean echo derived pressure gradient
(PG) across the aortic valve of 70 +- 28 mmHg.
In the case of low flow rate, static pressure gradient
plays a main role in the total pressure loss.
Recent wind tunnel measurements [1, 2] have determined that this also holds for developing boundary layers with a modestly favorable or adverse pressure gradient
Many investigators have reported the presence of a threshold gradient for certain reservoir formations, so that there is no flow through porous media when the pressure gradient
is below this value, and the relationship between flow rate and pressure gradient
was found to be approximately a straight line that does not pass through the origin.
