An apparatus and methods for facilitating a reduction in data transmission bandwidth removes unnecessary data relating to encryption keys prior to sending a message or storing the encrypted information for a recipient. The compounds are potent inhibitors of Na+Ca2+ exchange mechanism. Also, the apparatus may include a buffer status unit to store a multiple information items to indicate one or more buffer characteristics of the buffer. The number of bits to use to insert channel quality information on the uplink control channel is provided. Alternatively, two separate banks of economizer heating surface may be employed. The composition includes at least one fatty acid methyl ester, at least one ethoxylated alcohol having an HLB ranging from about 10 to about 14, at least one alkyl polyglycoside having an HLB ranging from about 10 to about 14, at least one hydrotrope, an alkali metal silicate, at least one corrosion inhibitor in an amount effective to prevent corrosion on metals, and water.
