A resin composition for producing a molded article having a surface which has an appearance of a non-woven fabric, which comprises fiber piles of a carbonized polyacrylonitrile having a nitrogen content of 10% by weight or more, a size of 1 to 15 denier and a length of 0. The resettable layer has a magnetization that is set in a selected direction by at least one externally generated magnetic field. The removable wall panels and roof of an embodiment of the present invention aid in maintainability by providing enhanced access to critical system components such as the chiller assembly. The cytolytic activity of the Th1killer cells is mediated by Granzyme B-Perforin mechanism and results in apoptotic death of diseased cells. The epitaxial material provides an extra flow path for current to flow through to the silicide from the extension, as well as increasing the surface area between the sourcedrain and the silicide to reduce the contact resistance between the sourcedrain and the silicide.
