Abstract: Provided are an esterase mutant and use thereof. The amino acid sequence of the esterase mutant has a sequence as shown in SEQ ID NO: 1, and sites at which amino acid mutations occur include an N51G site.

Abstract: Describes are shutter disks comprising one or more of titanium (Ti), barium (Ba), or cerium (Ce) for physical vapor deposition (PVD) that allows pasting to minimize outgassing and control defects during etching of a substrate. The shutter disks incorporate getter materials that are highly selective to reactive gas molecules, including O2, CO, CO2, and water.

Abstract: Methods and apparatus for processing a substrate are provided herein. For example, a method for processing a substrate can includes selectively etching from a substrate disposed in the PVD chamber an exposed first layer of material, covering an underlying second layer of material, and adjacent to an exposed third layer of material, using both process gas ions and metal ions formed from a target of the PVD chamber, in an amount sufficient to expose the second layer of material while simultaneously depositing a layer of metal onto the third layer of material; and subsequently depositing metal from the target onto the second layer of material.

Abstract: A water transferring device is provided and comprises a body having a water passage chamber, a first water inlet joint having a first water inlet passage and connected to the body, and a water outlet joint having an outer water passage and an inner water passage. The first water inlet joint and the water outlet joint enable the inner water passage to be in communication with the first water inlet passage. The water passage chamber is in communication with the outer water passage. At least one of the first water inlet joint or the water outlet joint comprises a connection structure connected to the body and enabling the at least one of the first water inlet joint or the water outlet joint to be at least rotated for a specific angle around an axis of the at least one of the first water inlet joint or the water outlet joint.

Abstract: A drain pipe structure configured for a basin, comprising a drain pipe body for water drainage, at least one connecting seat, and at least one mounting seat. The at least one connecting seat is configured to be connected to the drain pipe body to be fixed relative to an axial direction of the drain pipe body and at least one of rotation direction about an axis of the drain pipe body. The at least one connecting seat comprises a first connecting member, and the at least one mounting seat comprises a second connecting member. The first connecting member is configured to be operatively coupled to the second connecting member to enable the at least one mounting seat to operatively move along the axial direction of the drain pipe body to be fixed to a predetermined position of the at least one connecting seat along the axial direction.

Abstract: A group dispatching method for a trunking communication system, a communication system and a storage medium are provided. The system comprises an interconnection server, a system server and at least one voice dispatch console. The method comprises: establishing a call connection between the first communication terminal and the interconnection server, selecting an idle voice dispatch console as a service access point, transmitting a second call establishment message to the idle voice dispatch console wherein the first call establishment message corresponds to a group call initiated by the first communication terminal to a target group, establishing a call connection between the idle voice dispatch console and the interconnection server when the idle voice dispatch console receives the second call establishment message, and the idle voice dispatch console establishing a call connection to the target group through the system server to receive and transmit voice.

Abstract: The present invention discloses a water-induced anti-counterfeiting paper and a preparation method thereof, belonging to the field of anti-counterfeiting technology of paper. The water-induced anti-counterfeiting paper consists of a base paper layer and an anti-counterfeiting label thereon. The anti-counterfeiting label is a colorless, invisible pattern or character, and does not have any effect on the appearance of the base paper. When contacting with water, a transparency of a location where the paper has the anti-counterfeiting label increases, and thereby a character or a pattern appears. After drying, the character or the pattern disappears, and the paper reverted to normal. The water-induced anti-counterfeiting paper may be prepared by method of printing the anti-counterfeiting label at a surface of the base paper by processes such as printing, code-spurting and inkjet printing according to requirements.

Abstract: The present disclosure provides a method for domesticating Saccharomyces cerevisiae which is resistant to fermentation inhibitors, high temperature and high concentration of ethanol. The method comprises a primary domestication and a secondary domestication of the S. cerevisiae, wherein the primary domestication comprises the steps of replacing the fermented mash with fresh liquefied mash and continuing fermentation when the ethanol content in the fermented mash reaches a higher concentration (>12% (v/v)), the replacement is performed for at least 20 times, and the time interval of replacements is 20-30 hours; the secondary domestication comprises the steps of performing high-temperature domestication on the primary domesticated strain by a temperature gradient and replacing the fermented mash for multiple times, wherein the temperature is raised by 0.5° C.-2° C. every 18-24 times of replacement. The domesticated S.
