P&Q University Lesson 4, · If the rock, even though hard, is rather friable in structure (such as a well-jointed basalt or trap rock), then larger holes farther apart may be used and still retain optimum fragmentation. On the other hand, if a radical series of fracturing is present, causing rapid attenuation of explosives detonation waves, then smaller holes closer together may be necessary.Jameson cell, · The Jameson Cell is a high-intensity froth flotation cell that was invented by Laureate Professor Graeme Jameson of the University of Newcastle (Australia) and developed in conjunction with Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of the Glencore group of companies).Game Informer Reviews, · Swapping out characters is an instant push of a button, which creates a more dynamic and interesting combat system than basic button mashing.
