Potentially identical objects are located across multiple computers based on stochastic partitioning of workload. Generally speaking, the compound of the present invention is useful for specific recognition of lipid vectors. One or more air vents of small size are located in a protected floor of the base collar at positions spaced within predetermined ranges of offsets from the dispensing opening so as to convey liquid into contact with the air vents in a manner to self-seal the air vents by surface tension of the liquid until an unbalance force is present. The system further includes a pipe arrangement with a first end in communication with the fill tube downstream from the sealing device and a second end in communication with the tank, the second end defining a maximum level for the fuel in the tank during the filling operation. In a medium that recordsplays back data including video data and control information, the control information includes information for accessing a specific portion of the video data. Each center frequency is selected to obtain substantially constant amplitude and phase response over a desired frequency range and capacitance tuning range.
