A pair of pants including ventilation openings is disclosed. The detection system comprises a plurality of conductive pads which include a plurality of conductive elements. The invention further concerns the conjugate molecules produced using such improved methods. After decompression and decoding, the image data are stored in a screen store and transmitted to the screen, for example an LCD flat screen, according to the instructions of a screen controller. The tissue fixation device includes an adjustable, flexible member formed by inserting one end portion of the flexible member through another end portion of the flexible member, and first and second sub-loops formed by crossing a portion of the flexible member over a different portion of the flexible member. They have good melt workability and are favorable to large-size blow molding and extrusion foaming.
