An exhaust aftertreatment filter has a pre-stressed layer bonded to the filter body at the outer periphery and compressively axially pre-stressed in an opposite axial direction to separational axial tensile stress to counteract the latter during regenerative heating, to minimize separational fracture and cracking. A healthcare transaction may be received from a healthcare provider computer. The method also includes epitaxially growing a semiconductor material within the recess and forming a lightly doped drain region adjacent the gate. Accordingly, the raw material is sufficiently reacted in a plasma reaction space of a restrictive volume, and a high temperature plasma reaction is more promptly performed. Information which can be read optically, such as bar codes or the like, may be accommodated on this flat laminar zone. The support member supports the display device on a side opposite the display screen.
