The report said the man's weakness on his left side was likely caused due to a small stroke, which is said to be a "rare" side effect of having an air cavity
in the brain.
The same air cavity
could be imaged using the transmission imaging mode, where ultrasound pulsed by the transducer is received by a sensor beneath the sample.
In this hydrophilic case, a simple vertical jet ejects from the free surface after impact but a subsurface air cavity
does not form, and this numerical result agrees well with the experiment result.
The air-water front surface inside the large-scale pipeline was not planar due to the formation of an air cavity
on top of the water column.
In addition, all three modes of heat transfer are present in any internal air cavity
An air cavity
is etched below the antenna, which is used to improve its performance.
But with a DSF, hot gases are trapped inside the vertical air cavity
which is at higher temperature than in the open space.
A microperforated panel (MPP) was added to cover the absorber, in some cases leaving an air cavity
The pressure sensor in the LPS001WP is based on a flexible silicon membrane formed above an air cavity
with a controlled gap and defined pressure.
Among the topics are the effect of air cavity
convection on the wetting and drying behavior of wood-frame walls using a multi-physics approach, condensation damage behind self-adhering membrane flashing and interior finishings on exterior residential walls, evaluating drainage characteristics of water resistive barriers as part of an overall durable wall approach for the building enclosure, and laboratory tests of water penetration through wall-window interfaces based on US residential window installation practice.
6-meter-wide air cavity
between, which potentially will reduce energy costs by 30%.
This is difficult to find in many absorptive products that are attached directly to a surface because of inadequate absorptive properties at low frequencies; however, the air cavity
created when suspending a ceiling grid below a structure allows great absorption at low frequencies.
