Usage of Low-pressure Lamps For Surface Cleaning
Low-pressure mercury-vapor lamps usually have a quartz bulb in order to allow the transmission of short wavelength light. If synthetic quartz is used, then the transparency of the quartz is increased further and an emission line at 185 nm is observed also. Such a lamp can then be used for the cleaning or modification of surfaces. The line 185 nm will create ozone in an oxygen containing atmosphere, which helps in the cleaning process, but is also a health hazard.

“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
“...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
—Kenneth G. Wilson (b. 1923)
“The blaze of reputation cannot be blown out, but it often dies in the socket; a very few names may be considered as perpetual lamps that shine unconsumed.”
—Samuel Johnson (1709–1784)
“All beauties contain, like all possible phenomena, something eternal and something transitory,—something absolute and something particular. Absolute and eternal beauty does not exist, or rather it is only an abstraction skimmed from the common surface of different sorts of beauty. The particular element of each beauty comes from the emotions, and as we each have our own particular emotions, so we have our beauty.”
—Charles Baudelaire (1821–1867)
“The disgust with dirt can be so great that it keeps us from cleaning ourselves—from “justifying” ourselves.”
—Friedrich Nietzsche (1844–1900)
