ʆ The palatal hook ( ̡) is a type of hook diacritic formerly used in the International Phonetic Alphabet to represent palatalized consonants. It is a small, leftwards-facing hook joined to the bottom-right side of a letter, and is distinguished from various other hooks indicating retroflexion, etc.
The IPA recommended that esh ( ʃ ) and ezh (ʒ) not use the palatal hook, but instead get special curled symbols: ʆ and ʓ. However, versions with the hook may have been used by some authors.
The palatal hook was withdrawn in 1989, in favour of a superscript j following the consonant (i.e., ƫ becomes tʲ). Xn--2oa.com~Site InfoWhoisTrace RouteRBL Check
℧.com Mho is an alternate, non-SI unit of conductivity which is equivalent to 1 siemens. Mho is derived from spelling ohm backwards and is written with an upside-down capital Greek letter Omega: , Unicode symbol U+2127 (℧). According to Maver[1] the term mho was suggested by Sir William Thomson.
The term siemens, as it is an SI unit, is used universally in science and often in electrical applications, while mho is still used primarily in electronic applications. Two reasons are usually given[citation needed] for using mho instead of siemens in electronic applications:
The inverted Omega and the mho, while not an official SI abbreviation, has the advantage of being less likely to be confused with a variable than the letter S when doing algebraic calculations by hand, where the usual typographical distinctions (such as italic for variables and Roman for unit names) are difficult to maintain. Likewise, it is difficult to distinguish the symbol S from the lower case s where second is meant, potentially causing confusion.
The term siemens could be confused with the large multinational electronics company Siemens. Xn--32g.com~Site InfoWhoisTrace RouteRBL Check
