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.

In the meantime, countries are working to improve logistics and uptake.

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.

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.

Three transport systems are used for the uptake of bases from the host organism.

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

This test takes about 4 minutes while the uptake is accumulated (calculated) by the machine software.

) 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.

Without at least partial public financing, the uptake of these new technologies will be slow and uneven.

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).

(b) Uptake of the unique opportunities of Common Agricultural Policy (CAP) reform and rapidly emerging EU biofuel markets

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.

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

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

This phenomenon has not been the subject of much research, so the actual mechanism of DNA uptake is not known.

Another application is CADq, which quantifies, e.g., the size of a tumor or the tumor's behavior in contrast medium uptake.

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

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.

Blood sugar is regulated by insulin, glucagons, and other hormones that control its release from the liver or its uptake by the tissues.

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

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.

A few provided estimates of the time period over which the estimated carbon uptake would occur through afforestation, reforestation, forest protection and woodland creation.

These measures have the double advantage of increasing long term crop productivity and enhancing uptake of CO2 from the atmosphere or abating CO2 emissions.

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.

This test procedure typically involves two tests performed in connection with each other an iodine uptake test and a scan (imaging) with a gamma camera.

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.

And her mammogram showed an area of very dense tissue, but her MBI showed an area of worrisome uptake, which we can also see on a color image.

Although the World Health Organization (WHO) has recommended including the hepB vaccine in routine immunization since 1992, its high price initially hindered its uptake in some developing countries.

This would require adequately addressing uptake problems with foreign technologies and ensuring that any technology market failures could be mitigated through appropriate regulatory responses and voluntary corporate initiatives.

The digital mammogram was read as normal and shows lots of dense tissue, but the MBI shows an area of intense uptake, which correlated with a two centimeter tumor.
