A method of treating a tapered vessel with radiation. The compositions contain inter alia polymers containing perfluoroalkyl groups, wherein 55 to 100% of the RF groups contain 6 carbon atoms. Data stored in the memory cells can be non-destructively determined by applying a read voltage across the memory cells. A first output power level associated with simultaneously transmitting a first set of one or more traffic streams on the forward link is initially determined. A load associated with the service is determined. The article comprises a foil sheet having a fabric overlay adhered to one side.
