Compositions containing a therapeutic peptide covalently linked to Vitamin B12 at the 5\u2032-hydroxyl group of the ribose moiety of \u03b1-ligand are described. The method includes patterning an oxide layer to form an opening between the two neighboring sensor elements on the substrate. During a period when graphic data held in the SRAM is supplied to a pixel and a display is performed, the supply of the power source voltage from the power source voltage control circuit is stopped, and operations of the data driver and the scan driver are stopped. The catching mechanism may also include a braking mechanism configured to accelerate the target vehicle, and thus slow the KEST vehicle, as the catching mechanism and target vehicle travel along one or more tethers of the KEST vehicle. Edge of the wafer is polished using a pad and slurry while the wafer is grasped by the vacuum chuck. The holding levers include hinged sliding elements that slide in associated guide grooves in the pull-out element or bar.
