In numerical terms the most important Aboriginal concentrations are located in Queensland, New South Wales, Western Australia, and Northern Territory.
Flotation is one of the most important mineral concentration techniques.
Perhaps most important, higher CO2 concentrations reduces the quality of cereals, that is, their protein and starch content, taste and mineral components (and hence nutritional value).
The model application to the Lausitz mining district (Germany) shows that the most important factors controlling concentrations and discharge of sulfate are mixing/dilution with ambient groundwater and the rates of biological sulfate reduction during subsurface transport.
Response surface methodology (RS M, based on a Box Behnken design (BBD) was used to optimize three of the most important operating variables (concentrations of TCPO, Amplex red and pH effect) at peroxyoxalate-chemiluminescence (PO-CL) system.
"The most important thing is concentration.
The most important measure of concentration is the variance, denoted by Var X) and defined by Var X) = E{[ X − E X ]2.
