DOE This cover stock is 30% post-amsumer waste and 30% preconsumer waste, and is recydable. .I The sample will also be examined to determine if it consolidated after being deposited within the volume of the ring. In the currently envisioned design, this device will operate only at ambient pressures. FlJTUREi WORK Plans for the next quarter include completion of the design of the uncompacted bulk porosity test device mentioned above, continued work on the interactive data base of HGCU ash
