An ownership tag in a special area of memory of a computer system identifies an owner of the computer system by displaying the ownership tag during initialization of the computer system. A data file including metadata of the media assets in the media library is stored in the handheld device. Stream flow rate target values are developed based on the on-line process data and include intended flow rates through each heat exchanger to equalize each of the cool process stream outlet temperatures. In another device, a rigid or semi-rigid barrier member is removably attached to a layer of bioabsorbable adhesion-preventing material by a controlled adhesive.
