The term pervaporation is a portmanteau of the two steps of the process: (a) permeation through the membrane by the permeate, then (b) its evaporation into the vapor phase. This process is used by a number of industries for several different processes, including purification and analysis, due to its simplicity and in-line nature.
For example, laundry on a clothes line will dry (by evaporation) more rapidly on a windy day than on a still day. Three key parts to evaporation are heat, atmospheric pressure (determines the percent humidity), and air movement. On a molecular level, there is no strict boundary between the liquid state and the vapor state.
Examples of this usage include the "vaporization" of the uninhabited Marshall Island of Elugelab in the 1952 Ivy Mike thermonuclear test. [2] Many other examples can be found throughout the various MythBusters episodes that have involved explosives, chief among them being Cement Mix-Up , where they "vaporized" a cement truck with ANFO.
Pathophysiology (or physiopathology) is a branch of study, at the intersection of pathology and physiology, concerning disordered physiological processes that cause, result from, or are otherwise associated with a disease or injury.
Relative clauses are often used for circumlocution in English. [4] For example, [Firefighters] are the people who you call when your house is on fire. A [spider] is an arachnid that catches insects in its web. Synonyms and simile are two other common circumlocution strategies. [4] A pomegranate could be described using these techniques as follows:
Words with the middle part of the word left out are few. They may be further subdivided into two groups: (a) words with a final-clipped stem retaining the functional morpheme: maths (mathematics), specs (spectacles); (b) contractions due to a
Fluid catalytic cracking is a commonly used process, and a modern oil refinery will typically include a cat cracker, particularly at refineries in the US, due to the high demand for gasoline. [10] [11] [12] The process was first used around 1942 and employs a powdered catalyst. During WWII, the Allied Forces had plentiful supplies of the ...
