In aspects of the present invention, a method is disclosed to form a lamina having opposing first and second surfaces. The treated gas is then purified by adsorption of the mercaptans in first enclosure A1. Then, a via opening is defined in the encapsulating dielectric layer, and a planar interlevel dielectric layer is deposited over the encapsulating dielectric layer and within the via opening. The compounds are suitable for the treatment of fatty acid metabolism and glucose utilization disorders, disorders relating to insulin resistance are involved as well as demyelinating and other neurodegenerative disorders of the central and peripheral nervous system. A pressure vessel, which is connected to the emergency feed line, contains a certain volume of emergency water which is pressurised by a gas, so that, in case of a power failure, an emergency water flow establishes through the open cooling circuit.
