Essentially, to deliver anesthesia, you want as pure oxygen as possible, because eventually you're going to dilute it essentially with the gas.

Because there's no oxygen there, it's the largest reservoir of hydrogen sulfide on Earth. Shipwrecks are perfectly preserved.

We're all breathing air right now. Air is a mixture of oxygen and nitrogen, about 20 percent oxygen. About 80 percent nitrogen is in our lungs.

However, an excited state zwitterionic isomer exists in which H is transferred from the oxygen (giving an oxygen anion) to the nitrogen (giving a protonated nitrogen cation).

Whereas, if you wanted to talk about your project involving oxygen, girls, aircraft actually, I would like to hear that talk, but statistics say it's not so good.

This can be done by addition of various forms of rate limiting nutrients and electron acceptors, such as phosphorus, nitrogen, oxygen, or carbon (e.g.

This part occurs at a medium depth and has a relatively low salinity (34.84 34.89 parts per thousand), low temperature () and high oxygen content compared to the layers above and below it.

He had told me that the first time they covered his head with a plastic bag and tied it at the bottom, so that you feel that every breath was the last particle of oxygen left in this life but one keeps taking those last breaths.

What if you're in surgery and the power goes out? No lights, no oxygen and your anesthesia stops flowing. It happens constantly in hospitals throughout the world, turning routine procedures into tragedies. Erica Frenkel demos one solution the universal anesthesia machine.
