The invention provides proteins from group B streptococcus and group A streptococcus, including amino acid sequences and the corresponding nucleotide sequences. The method includes receiving a request for dynamic content from a user and determining a source for the dynamic content. The fluid chamber has a first length and a first width. The transactions are executed in a manner that ensures the atomicity and durability of each transaction. The first gate, semiconductor, source, and drain members form a first TFT, and the second gate, semiconductor, source, and drain members form a second TFT. At least one of said side support members is movable along said set of first grooves into contact with the portable equipment placed on said tray and at least another one of said side support members is movable along said set of second grooves into contact with the portable equipment placed on said tray.
