The widespread belief that bubble algorithms and other modifications which produce deeper stops are more efficient than the dissolved phase models is not borne out by formal experimental data, which suggest that the incidence of decompression symptoms may be higher for same duration schedules using deeper stops, due to greater saturation of ...
Air bubbles rising from a scuba diver in water A soap bubble floating in the air. A bubble is a globule of a gas substance in a liquid. In the opposite case, a globule of a liquid in a gas, is called a drop. [1] Due to the Marangoni effect, bubbles may remain intact when they reach the surface of the immersive substance.

It is widely used to measure minimum, maximum (or first bubble point) and mean flow pore sizes, and pore size distribution in membranes [1] nonwovens, paper, filtration and ultrafiltration media, hollow fibers, [2] ceramics, etc. In capillary flow porometry an inert gas is used to displace a liquid, which is in the pores. The pressure required ...
