A hot-air lid for containers used for cooking and frying is proposed. The reactive adhesive system can be a one or two-part system. The data storage device may identify one or more units of memory allocation in the erase before write memory as containing invalid data based on the specified logical address and data to be invalidated. The double-jointed bolt has a mounting portion with a hook or coarse threads to engage a vertebra, and the mounting portion is attached to a pivot post in a manner that allows the pivot post to be rotatable about a common axis in respect to the mounting portion. The array substrate according to an embodiment includes a pixel electrode in a pixel region; a common electrode in the pixel region, the common electrode being parallel to the pixel electrode; a first electrode in the pixel region and crossing the pixel and common electrodes; and a second electrode in the pixel region, the second electrode being parallel to the first electrode.
