Method of selectively removing volatile components from a composition, comprising coating the composition onto a first substrate surface of a substrate, wherein the composition comprises a nonresident volatile component and a resident volatile component. The at least one feedthrough includes an insulator having an entry face and an exit face, and at least one non-linear conductor is configured to extend, within the insulator, from the entry face to the exit face to provide the conductive path, wherein the entry and exit faces are not substantially parallel opposite faces of the insulator. The receiving groove is configured for receiving the SIM card therein. An executable that is attempting to execute is intercepted by a protection module that consults a database of stored rules over a secure channel to determine whether or not the executable can be identified as a permitted executable and whether or not it has permission to execute on a particular computer system under certain specified conditions.
