trituration

There was no sign of disease, but the edges were white and worn-looking, as if by some trituration.

The position near the coast of all the craters composed of this kind of tuff or peperino, and their breached condition, renders it probable that they were all formed when standing immersed in the sea; considering this circumstance, together with the remarkable absence of large beds of ashes in the whole archipelago, I think it highly probable that much the greater part of the tuff has originated from the trituration of fragments of the grey, basaltic lavas in the mouths of craters standing in the sea.

This opened the possibility that the rough process of trituration was not merely segregating the stem cells from the tissue.

The standard process for isolating stem cells from neural tissue required roughing up the tissue and then sluicing it aggressively through a pipette, a process known as trituration.

Repeated experiments, however, have established that pebbles are not at all necessary to the trituration of the hardest kinds of substances which can be introduced into their stomachs; and, of course, the usual food of fowls can be bruised without their aid.
