A dual edge triggered retention flip-flop reduces clock tree power dissipation in an active mode and leakage power in a low-power mode. The manual disconnection unit is wired in series with the fuse and provides a user selectable circuit interrupt. Embodiments of the marine fuel composition can have a sulphur content of about 0. The next step is forming from the hydrogen gas a plasma having an ion density in the range between 1010 and 1013 cm3 and an ion energy lower than 30 eV The last step is exposing the workpiece to the plasma for a predetermined time. The response message including a reason for rejection when the specific media is unsupported by the IWF.
