1.   Around half of the nitrogen in the burnt biomass may be released as nitrogen gas.

2.   A more ambitious idea, injecting nitrogen gas into the tanks when the planes are on the ground, to reduce the amount of oxygen, is under development.

3.   After its release, the Wake Shield, as commanded, began to expel a stream of nitrogen gas to push it away from the shuttle.

4.   In hopes of eliminating the problem, engineers used inert nitrogen gas instead of compressed air to move the fluid when making new gyroscopes to be installed on Hubble.

5.   It was inflated with nitrogen gas within minutes and looked like a silver parachute.

6.   Now, to sample wastes from low down in the tanks, technicians sometimes pump in inert nitrogen gas to preclude an explosion.

7.   Nitrogen, in the form of nitrates and other compounds, is converted by bacteria in the stream bed into nitrogen gas, which bubbles up into the atmosphere.

8.   The fluid could contain nitrogen gas or salt water, or even an antibiotic for fish with hook wounds.

9.   The fluid then compresses the nitrogen gas, from which it is separated by a diaphragm or bladder.

10.   The gas is normally formed by the breakup of oxygen molecules exposed to sunlight in the presence nitrogen oxide gases.
