In the absence of hematemesis, an upper source for GI bleeding is likely in the presence of at least two factors among black stool, age 50 years, and blood urea nitrogen creatinine ratio 30 or more.

This yields transformation urea and water in an equimolar ratio.

The urea cycle (also known as the Ornithine cycle) is a cycle of biochemical reactions occurring in many animals that produces urea ((NH2)2CO) from ammonia (NH3).

It's nitrogen narcosis.

Nitrogen oxides (NOx)

It's nitrogen narcosis.

Let's see, we have one nitrogen here, we have one nitrogen there.

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

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

Air is a mixture of oxygen and nitrogen, 20 percent oxygen, 80 percent nitrogen.

Ornithine is an amino acid that plays a role in the urea cycle.

The nitrogen has two problems.

It decays into nitrogen 14.

And how much nitrogen 14?

That's nitrogen with three hydrogens.

Zeolite it's not new zeolite removes nitrogen from air and nitrogen is 78 percent of air.

Urea or carbamide is an organic compound with the chemical formula CO(NH2)2.

A feature of diatoms is the urea cycle, which links them evolutionarily to animals.

Snow had found that the proportion of urea in the urine of his patients was low and concluded from this that urea was accumulating in the blood, and therefore proposed bloodletting to counter this.

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.

Now you know, you've got nitrogen in your protein, we've got nitrogen in our DNA so nitrogen is part of us, part of, you know, many many living things.

Yields 4 moles of nitrogen monoxide.

Nitrogen has 14 atomic mass units.

Gradual loss of nitrogen, calcium, phosphorus.

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.

A typical industrial plant that makes urea can produce up to 1500 tons a day.

In chemistry, N represents the element nitrogen.

If you did, it would be nitrogen,

And that reaction produces some nitrogen monoxide.

What happens to all that nitrogen there?

Now we have our own liquid nitrogen.

But nitrogen gas specifically is actually N2.

You have much more nitrogen hanging out.

There's no nitrogen and it turns sterile.

Bird disputed that increased urea in the blood was the cause of kidney disease and doubted the effectiveness of this treatment, citing the results of François Magendie, who had injected urea into the blood, apparently with no ill effects.

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

These products include diammonium phosphate, triple superphosphate, potassium chloride, potassium sulphate, anhydrous ammonia, urea and refined sulphur.

Their findings, published in 2011, that diatoms have a functioning urea cycle was highly significant, since prior to this the urea cycle was thought to have originated with the metazoans who appeared several hundreds of millions of years after the diatoms.

So that's where we get our nitrogen from.
