DEPOSITS IN CYCLOPROPANE FLOWMETER TUBES

Cyclopropane Anæsthesia

TLHIS paper is based on my experience of one thousand cases of cyclopropane anaesthesia personally conducted by me since October, 1938, both in hospital and in private. But before discussing these it might be convenient for me to mention here something about the drug itself. HISTORY. Cyclopropane was first isolated in Germany in 1882 by Freund, who also demonstrated its chemical structure, C 3H...

Cyclopropane Anesthesia

An electromagnetic catheter-flowmeter.

An electromagnetic flowmeter incorporated into a catheter is described. The catheter is introduced into the aorta via the femoral artery. The flow sensor is located some distance below the catheter tip and is sensitive to flow at right angles to the catheter. A crater-like elevation at one end of the transducer lumen permits funnel-like connection of the transducer to the ostium of an aortic br...

YAF: Yet Another Flowmeter

A flow meter generates flow data which contains information about each connection observed on a network from a stream of observed packets. Flow meters can be implemented in standalone measurement devices or inline on packet forwarding devices, such as routers. YAF (Yet Another Flowmeter) was created as a reference implementation of an IPFIX Metering and Exporting Process, and to provide a platf...

Biosynthesis of Cyclopropane Compounds

Oleic acid was converted to dihydrosterculic acid (9,10methyleneoctadecanoic acid) by Lactobacillus arabinosus cells. This was established by the mass spectra of branched chain esters formed by reductive opening of the cyclopropane ring of the corresponding cyclopropane fatty esters. The mass spectra allowed unambiguous assignment of the ring location to position 9,10. Oleic acid-9,10-d2 was co...
