Column 3: PnL Unexplained --- This is calculated as PnL - PnL Explained (i.e., Column 1 - Column 2) Column 4: Impact of Time --- This is the PnL due to the change in time. Column 5: Impact of Prices --- This is the PnL, i.e., the change in the value of a portfolio due to changes in commodity or equity/stock prices.
In chemistry, a nitride is a compound of nitrogen where nitrogen has a formal oxidation state of â3. Nitrides are a large class of compounds with a wide range of properties and applications.The nitride ion, N 3â , is never encountered in solution because it is so basic that it would be protonated.Its ionic radius is estimated to be 140 pm.Related to but distinct from nitride is pernitride, N 2 2â .itrides are a large class of compounds with a wide range of properties and applications.

Nitrites are the byproduct of the ammonia-eating bacteria, and are also highly toxic to fish. Like the cycling in step one, you must build up enough nitrites to form a second colony of bacteria that will dispose of them as they are produced.
