Indexing: Meaning and Methods | Milling | Industries ...
The operation of rotating the job through a required angle between two successive cuts is termed as indexing. This is accomplished with the help of a milling attachment known as dividing head, which is an accessory to the milling machine. It helps to divide the job periphery into a number of equal divisions, i.e., square, hexagonal octagonal, etc.

Olivine Weathering against Climate Change
One natural process has since the origin of the Earth removed almost all the CO2 that was ever produced by volcanism. That process is the reaction of CO2 and water with rocks, a process known as weathering. It is a logical choice to see if we can use the same process to remove also the vastly higher CO2 emissions caused by burning in a few hundred years the fossil fuels that …

Abstract. New evidence has emerged for a different type of platy spinifex texture that has not previously been documented in the existing literature, in this case from 2·8 Ga high-Mg basalts in the Murchison Domain of the Yilgarn Craton, where petrographic and geochemical evidence shows that the dominant platy mineral is pyroxene, rather than olivine.
