Improved manometric fluid

An improved embalming fluid formula.

Although a local modification of the usual alcohol-glycerinephenol-formaldehyde embalming formula has proved generally satisfactory through the years, continued price advances in the principal items of this formula led to its re-examination from a number of standpoints. A first consideration was the investigation of the possibility of substitutes for those items, such as ethanol and glycerine, ...

Improved manometric setup for the accurate determination of supercritical carbon dioxide sorption.

An improved version of the manometric apparatus and its procedures for measuring excess sorption of supercritical carbon dioxide are presented in detail with a comprehensive error analysis. An improved manometric apparatus is necessary for accurate excess sorption measurements with supercritical carbon dioxide due to the difficulties associated with the high sensitivity of density for pressure ...

Combined Manometric and Ph Recording

Oesophageal acid clearing has been measured by counting the number of swallows needed to raise the lower oesophageal pH from 1.5 to 5.0 after instilling 15 ml 0 1 N hydrochloric acid. Normal subjects all had a result less than 12, as did asymptomatic patients with hiatal hernias. Patients with symptomatic gastrooesophageal reflux tended to have abnormal acid clearance, as did those with oesopha...

Manometric Analysis of Gas Mixtures

A Manometric Respirometer for Snails

IN the course of an investigation into the physiology of the edible snail {Helix pomatia L.), it became necessary to measure the respiration individually of large numbers of animals. A system in which CO,-free air was passed over the animals and then through baryta was tried but rejected because the snails apparently dislike currents of air, tending to withdraw into their shells. Analysis of ga...
