Some sources distinguish "diacritical marks" (marks upon standard letters in the A–Z 26-letter alphabet) from "special characters" (letters not marked but radically modified from the standard 26-letter alphabet) such as Old English and Icelandic eth (Ð, ð) and thorn (uppercase Þ, lowercase þ), and ligatures such as Latin and Anglo-Saxon Æ (minuscule: æ), and German eszett (ß; final ...
The word diacritic is a noun, though it is sometimes used in an attributive sense, whereas diacritical is only an adjective. Some diacritics, such as the acute ó , grave ò , and circumflex ô (all shown above an 'o'), are often called accents. Diacritics may appear above or below a letter or in some other position such as within the letter or ...
When measuring vacuum, the working liquid may evaporate and contaminate the vacuum if its vapor pressure is too high. When measuring liquid pressure, a loop filled with gas or a light fluid can isolate the liquids to prevent them from mixing, but this can be unnecessary, for example, when mercury is used as the manometer fluid to measure ...
More precise transcription will use the fricative symbols with the lowering diacritic, [β̞, ð̞, ɣ˕] (the last symbol may be rendered as [ɣ̞], but that may not display properly in some browsers). Czech, on the other hand, requires the opposite: Its fricated trill, which is a separate phoneme, may be transcribed as a raised trill, [r̝].

The pressure is measured either by using laminar plates, an orifice, a nozzle, or a Venturi tube to create an artificial constriction and then measure the pressure loss of fluids as they pass that constriction, or by measuring static and stagnation pressures to derive the dynamic pressure.
A McLeod gauge is a scientific instrument used to measure very low pressures, down to 10 −6 Torr (0.133 mPa). It was invented in 1874 by Herbert McLeod (1841–1923). [ 1 ] McLeod gauges were once commonly found attached to equipment that operates under vacuum , such as a lyophilizer .
