An exemplary method for making a metallic cover includes the following steps: providing a raw metallic block ; rolling a pressing machine on the metallic block to form a preformed body ; and machining the preformed body 40 in a high precision machining process to yield a metallic cover. The disclosure provides administration of enterically coated cysteamine compositions to treat fatty liver disorders, such as non-alcoholic fatty liver disease and non-alcoholic steatohepatitis. These compositions are useful as aerosol propellants, refrigerants, cleaning agents, expansion agents for polyolefins and polyurethanes, refrigerants, heat transfer media, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents, and displacement drying agents. Each of the RFID circuit elements To has an IC circuit part for storing information and an antenna connected to said IC circuit part. By controlling the internal additive utilized and modifying the type of fibers formed, e. determining least cost alternative network resources available for achieving the communication at the user selected default quality of service and the required bit rate, iv.
