Composite pre-forms are molded at high pressure to form composite parts that can be used in place of metal-based high performance parts, such as the outlet guide vanes found in turbofan jet engines. The tags store a unique customer identification number as well as other frequent purchase information. Biosorbents of this type are used, in particular, for removing heavy metals from aqueous solutions. The two entities are determined to satisfy the entity resolution threshold on the basis of the one or more commonly-related entities. Thereby, a storage capacity requirement from the buffer memory is reduced. The voltage divider chain is connected with the radio-frequency power amplifier via a switching device.
