Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature.

It's nitrogen narcosis.

In either case, the aim is to produce nitrogen gas, rather than nitrogen oxides.

Nitrogen fixation by cyanobacteria in coral reefs can fix twice the amount of nitrogen than on land around 1.8 kg of nitrogen is fixed per hectare per day.

Nitric oxide, or nitrogen oxide, also known as nitrogen monoxide, is a molecule with the chemical formula NO.

Lighter isotopes of nitrogen are preferred in the reaction, leaving the heavier nitrogen isotopes in the residual matter.

Pressurized helium from a 35 liter tank is used to force fuel into the engine.

Ammonia nitrogen was removed via nitrification denitrification up to 40 when nitrogen loading rates were of 0.18 kg N (m3 d).

In chemistry, N represents the element nitrogen.

The RMS velocities of diatomic nitrogen and oxygen are very similar and thus no change occurs in the ratio of oxygen to nitrogen.

It had the first pressurized fuselage in the Soviet Union and first flew on 27 November 1946.

If the mist or aerosol from a pressurized container is fine, a pool may not be formed.

The Boeing Model 307 Stratoliner was the first commercial transport aircraft to enter service with a pressurized cabin.

) This is typically done with chlorine and nitrogen gas.

An analogous process for organic nitrogen compounds is deamination.

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).

The Dearman engine differs from former nitrogen engine designs in that the nitrogen is heated by combining it with the heat exchange fluid inside the cylinder of the engine.

Nitrogen, phosphorus, and sulfur are also needed in relatively large quantities.

It is not often used today, but is used for sterilizing some things that cannot withstand pressurized heating, such as plant seeds.

Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen.

Like other beans, it hosts bacteria that fix nitrogen in the soil.

Water from many so called improved sources is contaminated because of poorly maintained or intermittently pressurized networks or untreated and contaminated source water.

The first 540 megawatt (MWe) pressurized heavy water reactor (PHWR) unit at Tarapur has commenced commercial operations about seven months ahead of schedule.

On the other hand, if a pressurized container dispenses product in a stream, a pool may be formed that may then be aspirated.

The amount of nitrogen and sulfur circulating through the Earth system has doubled.

Biological nitrogen fixation (BNF) could help to improve soil fertility and crop productivity.

Bioethanol has been shown to reduce nitrogen oxide emissions by 50 per cent

Douglas would later develop a version of this plane that was pressurized and five feet longer this redesigned plane would become the DC 6.

Now the one thing that I forgot to mention, is that to obviate the problem of the nitrogen narcosis all of those blue dots in our body you remove the nitrogen and you replace it with helium.

This design lowers the emissions of both nitrogen oxides (NO x ) and carbon dioxide (CO2).

It is the second most common type of electricity generating nuclear reactor after the pressurized water reactor (PWR), also a type of light water nuclear reactor.

Auroras and the atmosphere Auroras result from emissions of photons in the Earth's upper atmosphere, above , from ionized nitrogen atoms regaining an electron, and oxygen atoms and nitrogen based molecules returning from an excited state to ground state.

In the '60s already, through the green revolution and the Haber Bosch process of fixing nitrogen from the atmosphere you know, human's today take out more nitrogen from the atmosphere than the whole biosphere does naturally as a whole.

And if we see the nitrogen dioxide and oxygen, I think we have the perfect E.T.

He observed that mixtures of alkali metal oxides and carbon react at high temperatures with nitrogen.

Ammonium perchlorate can also be used, as it decomposes mainly into chlorine, nitrogen, and oxygen when heated.

The excited molecular nitrogen (atomic nitrogen being rare due to high stability of the N2 molecule) plays its role here as well, as it can transfer energy by collision to an oxygen atom, which then radiates it away at the green wavelength.

To this effect, the United Kingdom adopted the Ammonium Nitrate Materials (High Nitrogen Content) Safety Regulations in 2003.

The nitrogen just sort of floats around in our blood and tissues, and that's all fine, that's how we're designed.

These compounds consist of elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, calcium, iron, zinc, magnesium, manganese, and so on.

A characterization of these fibers was given as well as hypotheses for their growth in a nitrogen atmosphere at low pressures.

Frank Caro process and Ostwald process dominated the industrial fixation of nitrogen until the discovery of the Haber process in 1909.

With liquid nitrogen, a blister may form at the treatment site, but it will slough off in two to four weeks.
