Organisms of all sizes are found on bedding plane assemblages; this shows that they were commonly preserved in life position, as currents would preferentially remove smaller specimens.

PCR has been found to improve the physical properties of electrolytically deposited metals (the reverse current preferentially removes dendrites) and may also reduce polarization effects (can improve purity of product and cell efficiency).

Dust storms cause soil loss from the dry lands, and worse, they preferentially remove organic matter and the nutrient-rich lightest particles, thereby reducing agricultural productivity.

The principle underlying variations in δO18 is embodied in this statement: In the hydrologic cycle, evaporation preferentially removes water with (i.e. light oxygen).

MGMT preferentially removes alkyl groups from O-alkyl guanine than from O-alkyl thymine.

As a result, differential erosion preferentially removes the shale and mudstone and exposes these paleochannels as ridges.

Both species of fungi cause brown rot decay, preferentially removing cellulose and hemicellulose from the timber leaving a brittle matrix of modified lignin.

That has been demonstrated experimentally to be the case with alkali feldspars, where weathering can preferentially remove the alkali cation (K1+ or Na1+) but leave an Al-Si remnant structure on the surface of feldspar grains3.

MDEA's popularity as a solvent for gas treating stems from several advantages it has over other alkanolamines, especially its ability to preferentially remove HS (and slip CO) from sour gas streams.
