It was further determined that if one calculates the Roman foot from the quadrantal, the cube equal to 80 librae of water, and the libra is calculated from the sample weights, one obtains a foot that goes from the length of the pes Aebutianus to a maximum of about 131.8. Paris lines (297.3428 mm.).
Crystallization is also a chemical solidâliquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering crystallization occurs in a crystallizer.
Vacuum metallization, also known as thermal evaporation, is the most common PVD (Physical Vapor Deposition) process used to apply metal alloys under vacuum. Where polyester film is concerned, aluminum is vaporized inside a vacuum chamber, and then bonded to a polyester sheet to achieve a uniform metalized layer.
