A query caching system and method for enabling the caching of software object instances at the granularity of query level. Preferred photoresist compositions of the invention comprise one or more materials having a water contact angle that can be changed by treatment with base andor one or more materials that comprise fluorinated photoacid-labile groups andor one or more materials that comprise acidic groups spaced from a polymer backbone. Compounded pellets including inorganic and organic fillers resulting in products in cellular or foamable form with and without solid skin surfaces has also been realized by providing melt combinations within the pellets primarily comprising talc and a perfluoropolymer, and additives as needed to provide desired property differentiation. The first circuit may be further configured to compare the data signal with the random number signal and when the data signal matches the random number signal generate a first of the control signals and when the data signal fails to match the random number signal generate a second of the control signals. Portions of the interlayer dielectric layer are removed to expose portions of the raised portion of the etch-stop layer. The system can be more compact and energy efficient than comparable electrically-based pressurization systems when incorporated into the fuel cell reformation and water management systems as a whole.
