The invention relates to methods of forming shaped articles from suspensions which include ceramic or metallic powder, or from solutions or suspensions which include one or more pharmaceutical substances or other components. Embodiments include transformations, code, state machines or other logic to provide computer security by receiving over a secure network connection a message to signal physical presence to a trusted platform module and by signaling physical presence to the TPM in response to receiving the message. The cover covers the casing and has an outer thread and an opening defined radially through the cover. \u201cP1\u201d and \u201cP2\u201d are independently a polymerizable group.
