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.

Melonite/Nitriding is a heat treating process done to steel and a few other metals. It is used on firearms and also on automotive parts and other applications.Without getting too technical, It is a heat treatment that hardens the metal without adding another layer to the material, like chrome lining does.There are different types of Nitriding used on metal.t is used on firearms and also on automotive parts and other applications.
