Our results suggest that microbubbles offer a simple and robust method of modulating mass transfer in cell-seeded hydrogels through mild pressurization, and the methodology may be expanded in the future to include focused ultrasound for improved spatio-temporal control.
Further investigation into the mechanical influence of the base on the composite material suggests that underlying pores may decrease interstitial fluid pressurization and applied strains, which may be overcome by alterations to the base structure.
It was observed that porcine pericardium TAV leaflets experienced significantly more flexure than bovine when subjected to opening pressurization, and that the flexure may be overestimated using a constitutive model derived from purely planar tensile experimental data.
Also, cabin pressurization systems fail occasionally, and some people may be vulnerable to the drop in pressure that occurs even in pressurized aircraft.
There may be associated re-pressurization if the system is compressible, if incompressible net loss or gain of injection fluid is the corresponding response.
This suggests that a shallow fault exhibiting stable, velocity-strengthening behavior at low slip rates may be weakened by thermal pressurization.
Unlike conventional tympanometry, WAI measures do not require pressurization of the ear canal, and so may be obtained on measurement systems that lack a direct method for assessing the extent of the acoustic seal.
This suggests that lava level, in addition to surface deformation and seismic activity, may be another tool for judging magma pressurization and eruptive potential.
In schools and large buildings, ventilation systems may be used to reduce radon entry due to pressurization of the indoor space.
This may be due to its ability to increase cement pressurization at the time of implantation and thereby the depth of cement penetration, though conflicting experimental findings have been reported (Oh et al. 1985, Shelley and Wroblewski 1988, Parsch et al. 2004, Lankester et al. 2007).
