A semiconductor process includes the following step. To prevent an occurrence of formations that obstruct the flow of fluid in the fluid conduit, a forecast is made as to whether a flow assurance curve will intersect an operating curve of the fluid conduit. The presence of zinc or titanium increases the resistance of the catalyst system to a sulfur and water-containing gas stream. The thermal sensitive resistor is preset to operate at a safety temperature within a predetermined thermal preference. Two or more application programs, running in independent operating systems, share user interaction state information including user data, user settings, andor application context information.
