A method for fabricating a mixed substrate that include insulating material layer portions buried in a substrate of semiconductor material. A donor web is disposed on one side of the path; a platen roller is disposed on the other side of the path and supports the sheet during printing. The present invention also includes an inert-type electrode composition, and methods for fabricating electrode compositions, used in processes for generating energy from fossil fuels. It is useful in the manufacture of medicaments for treating CHD, angina pectoris, myocardial ischemia, hemorrhagic shock, heart failure, and arrhythmia. The data is backed up into the \u201chidden\u201d backup storage.
