A cart is towed behind a combine harvester for collecting corn cobs and includes a conveyer belt feeding into a system for separating cobs from residue to be discharged and a tank for receiving and transporting the cobs. In particular, methods according to the present invention comprise dispersing nanocrystalline particles in the areas affected by smoke for sorption of smoke particulates and toxic compounds produced from a fire. The controller determines whether the text part includes only a predetermined code. Because the exterior of the wet wipes package is similar to a facial tissue carton, similar graphical treatments as applied to facial tissue cartons can be used to design an attractive package.
