Life Insurance Mortality Tables. Life insurance companies use what is called a Life Insurance Mortality Table (aka actuarial table or life table) to come up with policy rates. This table takes your age and calculates how many years you have left to live if you live to the average life expectancy.
Rust is the normal electrochemical process of metals returning to their natural unrefined state. It occurs when Iron, Oxygen and Water (air moisture) combine. The rusting process can be accelerated when Iron is subjected to nature's minerals, chemicals and temperature fluctuations.
Rust from Iron (III) oxides that is a very soluble iron oxide results in yellow rust. 1  Yellow rust is distinguishable in recessed areas of the metal parts/equipment where the rust âruns and dripsâ (solvated rust). 2  Yellow rust forms as a result of very high moisture content.ust from Iron (III) oxides with high oxygen and low moisture results in brown rust. 1  Brown rust is a drier rust than those mentioned above. 2  It is most likely atmospheric â having formed as a result of water and oxygen in the atmosphere and presenting as a reddish-brown crust on the metalâs surface.
