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.

Nitriding is a surface-hardening heat treatment that introduces nitrogen into the surface of steel at a temperature range (500 to 550Â°C, or 930 to 1020Â°F), while it is in the ferrite condition.as Nitriding Gas nitriding is a case-hardening process whereby nitrogen is introduced into the surface of a solid ferrous alloy by holding the metal at a suitable temperature in contact with a nitrogenous gas, usually ammonia. Quenching is not required for the production of a hard case.
