The wench I should have been courting now was journalism, that grisette of literature who has a smile and a hand for all beginners, welcoming them at the threshold, teaching them so much that is worth knowing, introducing them to the other lady whom they have worshipped from afar, showing them even how to woo her, and then bidding them a bright ...
Anorectal manometry. Anorectal manometry is a technique used to measure contractility in the anus and rectum. This technique uses a balloon in the rectum to distend the rectum and a pressure sensor at the internal anal sphincter to measure the presence or absence of the rectosphincteric reflex.
Complexometric titration (sometimes chelatometry) is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution.An indicator capable of producing an unambiguous color change is usually used to detect the end-point of the titration.DTA forms an octahedral complex with most 2+ metal cations, M 2+ , in aqueous solution. The main reason that EDTA is used so extensively in the standardization of metal cation solutions is that the formation constant for most metal cation-EDTA complexes is very high, meaning that the equilibrium for the reaction:
