Described is a chemical-mechanical polishing composition comprising the following components: surface modified silica particles having a negative zeta potential of \u221215 mV or below at a pH in the range of from 2 to 6 one or more polyethylene imines water optionally one or more further constituents, wherein the pH of the composition is in the range of from 2 to 6. In certain implementations, a touch screen interface is provided with a plurality of icons that each represent seats around a table in a restaurant. For example, a search configuration application executing at a first computer system is utilized to generate a search configuration file, which controls the operation of a search agent when the search agent is executing at a target computer system and performing a search of storage devices act of the target computer system. The transmission rate can also include a local load coefficient which can be adjusted to either increase or decrease the transmission rate of a terminal to a server depending on the status of the servers. The assembly includes a division bar mountable in a vehicle rear door window opening to create at least two air passages on opposite sides of the division bar within the vehicle rear door window opening, to thereby minimize wind noise generated during movement of the vehicle when the vehicle front windows are closed with the vehicle rear windows being opened. This also frees the level two memory for other masterrequestors.
