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 heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on low-carbon, low-alloy steels.However, they are also used on medium and high-carbon steels, titanium, aluminum and molybdenum.n the plasma nitriding processes, nitrogen gas (N 2) is usually the nitrogen carrying gas. Other gasses like hydrogen or Argon are also used. Indeed, Argon and H 2 can be used before the nitriding process during the heating of the parts to clean the surfaces to be nitrided.
