A lock device includes a first lock part, a second lock part, which can be arranged on the first lock part in a fastening direction and is connected to the first lock part in a closing state, and an actuating element, on which the second lock part is movably arranged. To increase the efficiency of a lung segmentation technique, a region-based technique, such as region growing, is performed by a computer on a middle slice of the CT volume. The output of the head is increased by increasing a resistance change rate of a magnetoresistive element used as a reading element. For those tones in the second subset, perform FEQ along with ICIISI cancellation. The bottom cell includes a dye-sensitized mesoporous photovoltaic film. In the method, trenches are formed in a silicon substrate corresponding to a source region and a drain region.
