An apparatus and method for use in blood dialysis. More specifically, the invention utilizes nonwoven webs that include relatively low levels of multiple-component fibers having latent three-dimensional spiral crimp combined with fibers that do not develop spiral crimp. The remote condensing fingers are disposed circumferentially about a remote axis extending vertically through the remote housing. Each utilization measurement is converted to a corresponding utilization range of multiple utilization ranges. The aerodynamic cover assembly side walls and hatch provide a space for human habitation and increased cargo hauling capacity. In another embodiment, a flash apparatus includes a suppressor portion having a plurality of longitudinally elongated members spaced apart about a circumference of the suppressor bore, each elongated member being separated from adjacent elongated members by a longitudinal slot, at least one longitudinal slot having non-parallel sidewalls.
