<span>Eubacteria can be classified by their shapes: spirilla, bacilli, and cocci. These bacteria are prokaryotic, meaning their cells do not have defined nuclei. Researchers at The University of California Santa Barbara call them the "true" bacteria. Some Eubacteria live in places with very little oxygen, and organisms in this kingdom reproduce asexually through binary fission. This can occur as often as once every 20 minutes, contributing to the rapid growth of illnesses, such as strep throat and E. coli. Eubacteria acquire nutrition through three different means: absorption, photosynthesis or chemosynthesis.</span>
Is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).
There are many ways to test porosity in a substance or part, such as industrial CT scanning.
The term porosity is used in multiple fields including pharmaceutics, ceramics, metallurgy, materials, manufacturing, hydrology, earth sciences, soil mechanics and engineering.
