Abstract: An embodiment pressure vessel includes a nozzle part, a liner part, and a composite material part. The nozzle part extends upward and includes a first nozzle portion and a second nozzle portion connected to a lower side of the first nozzle portion and having a greater diameter than a diameter of the first nozzle portion, and an area of the second nozzle portion adjacent to the first nozzle portion in a top-down view defines a first boundary area. The liner part defines an inner space and surrounds a lower side of the nozzle part, and an upper end of the liner part covers the first boundary area, and the composite material part is coupled to an outer side of the liner part and is configured to surround the liner part.

Abstract: A display apparatus, a system, and controlling methods are provided. The display apparatus includes: a display configured to display a user interface (UI) screen; a receiver configured to receive a control signal from a remote control device; and a controller configured to move a cursor on the displayed UI screen based on the received control signal and, in response to the cursor being positioned in a preset area determined based on information about the UI screen, operate in a minute control mode.

Abstract: The present invention relates to a diaromatic amino acid substrate for cathepsin detection. When the substrate used for cathepsin detection is a polymer resulting from the binding of a protease-preferred amino acid and quencher to a diaromatic amino acid, cathepsin can be detected sensitively and accurately by fluorescence because cathepsin causes the protease-preferred amino acid and quencher to dissociate from the diaromatic amino acid, and fluorescence is recovered during this time.
