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...
متن کاملAn extension of the Cartesian diver micro respirometer technique.
A frequent criticism of the various microtechniques available for the measurement of small changes in gas volumes has been that mixing of two or more solutions at any desired time during the experiment is inconvenient or impossible. This criticism does not apply to the instrument designed by Heatley et al. (1) in which 2 drops, 1 containing a paraffin-coated steel sphere, may be mixed by magnet...
متن کاملEvaluation of a respirometer for neonates.
The adult (Wright) respirometer has been redesigned for neonates. A calibrated Krogh spirometer has been used to check the accuracy and a regression relationship derived over a range of minute volumes 0.4-2.8 l./min. The added resistance of 29 cm H,O/ l./sec lowered minute volume according to a second regression line which was also experimentally derived. Combining the two regressions allows tr...
متن کاملAutomatically Recording Respirometer.
Recently, several different types of devices have been developed which automatically record oxygen consumption of biological cultures. This article describes one of these devices and discusses its application.
متن کاملa study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
