The optical thickness Ï of a medium is a dimensionless quantity that characterizes the attenuation of optical radiation in the medium. The attenuation results from the joint action of light absorption and light scattering.he optical thickness Ï of a medium is a dimensionless quantity that characterizes the attenuation of optical radiation in the medium.

As nouns the difference between automation and automatization is that automation is the act or process of converting the controlling of a machine or device to a more automatic system, such as computer or electronic controls while automatization is a process of making an action of a higher animal reflexive.
Anabolism, as in âanabolic steroidsâ, refers to those metabolic processes that utilize energy to biosynthesize complex molecules and to generate growth. The reverse process is catabolism, whereby nutrients are broken down to release energy. Catabolic processes provide intermediates for synthetic or further catabolic pathways and release energy, usually as the energy carrier molecules ATP and NADPH. The following mnemonic may help in remembering the difference: A B C D : Anabolism = Biosynthesis ; Catabolism = Degradation.
