Results showed that the use of alternate pulsation reduced the vacuum fluctuations and increased the average vacuum in the short milk tube.
We interpret this decrease in work function as arising from the interfacial dipoles from the modified ZnO Cs2CO3 layer, which reduces the vacuum level, resulting in a lower electron injection barrier, thus facilitating electron injection [48].
The auxiliary vacuum cell helps to inhibit the excessive pressure growth in the beam-wave interaction area during the HERP-MILO operation, and the 6 vacuum pump ports can enhance the vacuum pumping speed and efficiently reduce the vacuum recovery time.
This limitation reduces the vacuum and cavitation caused by phalanx flexion, and thereby attenuates or eliminates the audible 'pop' or cracking of the knuckles.
When combined with joint discomfort, the resultant restriction to the speed, range of motion and separation of the articular surfaces would reduce the vacuum, which, in turn, would attenuate or eliminate the noisy collapse of cavitation.
Five specific results of this study can reduce the vacuum that currently exists between the knowledge and information available to healthcare professionals, and how that information is conveyed to the public.
A bypass hole delayed the vacuum rise and reduced the mean vacuum level on full occlusion.
The occurrence of micro-bubbles may be due to the silicon nitride windows bulging outward into the vacuum (under-pressure at the vacuum side), thus reducing the pressure in the micro-chamber, which may lead to partial de-gassing of the water.
The ethanol solution was concentrated by reducing the pressure and dried by vacuum.
Most of the vibrational bands observable between 8 and 16 µm appear strongly reduced in the vacuum emissivity spectrum with respect to the purged emissivity, due to thermal gradients in the sample (Logan and Hunt 1970) and to the weakening (disappearance in high vacuum) of the transparency feature in vacuum (Salisbury et al. 1991).
