Abstract: A display panel, a method of manufacturing the display panel, and a display device are provided. According to the display panel provided by the embodiment of the present application, a bonding structure is arranged between a display substrate and a circuit board to connect the display substrate and the circuit board together, and a width of the bonding structure is set to be 50 microns (?m)-200 ?m, so that when a plurality of display panels are spliced to realize a large-screen display, a width of an interval area between the adjacent display areas of the display panels may be significantly reduced.

Abstract: A cartridge type valve core structure of a water tap includes a cartridge casing and a valve core. The cartridge casing has an accommodation room therein. An outer wall of the cartridge casing is provided with a first engaging portion for connecting with the water tap. The valve core is disposed in the accommodation room. The valve core includes a control end, a water inlet end, a water outlet end, and at least one water room. The control end extends out of the cartridge casing from a top end of the accommodation room. The water inlet end extends out of the cartridge casing from a bottom end of the accommodation room. The water outlet end extends out of the cartridge casing from one side of the accommodation room. Through the aforesaid modular structure, the valve core can be mounted to the water tap quickly through the cartridge casing.

Abstract: The present invention provides an immunoassay method for the highly sensitive detection of amphetamines, methamphetamines, and methylenedioxy designer amphetamines in urine samples. Commercially available reagents for the determination of amphetamines and methamphetamines are used with a calibrator comprising a known amount of a substance selected from the group consisting of methylenedioxy designer amphetamines.
