If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate areas around volcanoes when they threaten to erupt. Yes, convergent boundaries are dangerous places to live, but with preparation and watchfulness, the danger can be lessened somewhat.
Nitrification, as stated above, is formally a two-step process; in the first step ammonia is oxidized to nitrite, and in the second step nitrite is oxidized to nitrate. Different microbes are responsible for each step in the marine environment.
1 The solution nitriding process, SolNitÂ®, is performed in the austenitic phase of steel. At temperatures above 1922Â°F (1050Â°C), the thermal dissociation of nitrogen can be used to transfer into and solve nitrogen in stainless steels.  Nitrogen case depth up to .1 inches (2.5 mm) can be reached in 24 hours.
