A chemical construct for use with solution phase chemistry comprises a reversible attachment unit and one or more attribute conferring units. A second type of MEMS resonator that is fabricated using deep trench etching and occupies a small area of a semiconductor chip is taught. Also disclosed are wick-containing, laminated devices that are capable of separating fluids. The content processing subsystem is configured to access and utilize the online resource data to generate the program guide user interface when the online resource data is accessible via the network. Each closure element is movable by the common actuating drive between a parking position and a working position. This information is stored in a in an on-line database residing in the network system.
