ON ETHER-VAPOUR,

On the inhalation of the vapour of ether in surgical operations.

I have spoken of a knowledge of the strength of the vapour as being essential to a correct determination of the state of the patient at all times: and this brings us to the apparatus for the administration of the vapour, as, without a suitable one, the proportions of air and of vapour cannot be determined. I had the honour of shewing that these proportions could be easily and precisely controll...

Decomposition of Ethanol and Dimethyl Ether During Chemical Vapour deposition Synthesis of Single-Walled Carbon Nanotubes

In this study, we investigated carbon feedstock decomposition conditions on the synthesis of single-walled carbon nanotubes (SWNTs) by chemical vapour deposition. We simulated gas-phase thermal decomposition of ethanol and dimethyl ether (DME) at typical SWNT growth conditions using the chemical kinetic model, and confirmed the reaction trends and primary products using Fourier transform infrar...

Darth vapour

its membership – one of them contributed to the withdrawal of the arthritis drug Vioxx. With this track record, and the option to bank on some degree of community spirit among its membership, Kaiser Permanente may find it easier to gain the trust of the target population than the UK Biobank did. They also may want to find a different name for the project, for who would trust a bank these days? ...

Comparison of osteogenic potential of poly-ether-ether-ketone with titanium-coated poly-ether-ether-ketone and titanium-blended poly-ether-ether-ketone: An in vitro study

STATEMENT OF PROBLEM Poly-ether-ether-ketone (PEEK), a high-performance semi-crystalline thermoplastic polymer, has been employed to replace the metallic implant components in orthopedics. There were various studies performed in accordance to medical grade PEEK, but the relationship between titanium dioxide (TiO2)-coated PEEK, TiO2-blended PEEK, and untreated PEEK still remains complicated, eve...
