Abstract: Disclosed is a method for enhancing leaching of metals in zinc hypoxide powder by mechanochemistry coupling with sonochemistry, comprising the following: mechanical activation: a raw material containing zinc hypoxide powder is mechanically activated so that an activated material is obtained; and ultrasonic treatment: the activated material is mixed with an acidic leaching solution to obtain a mixture, the mixture is subjected to ultrasonic treatment, and a liquid phase is obtained as the leachate. Mechanochemical activation and ultrasonic chemistry synergistically enhance the leaching efficiency and leaching rate of multiple metals through the destruction and cavitation of the zinc oxide powder structure. This process can indirectly reduce the concentration of the used acidic leaching solution and shorten the leaching duration.

Abstract: A power free step auto reset clay thrower consisting of a base, a stepping rod, a support, a throwing arm holder, a throwing arm and an elastic member is disclosed. When the stepping rod is depressed, the throwing arm is forced by a first spring to move a link and a first linking member in turning the throwing arm forward for causing generation of a centrifugal force to throw a clay away from the throwing arm. When the throwing arm is thrown forward, the eccentric pivot joint stretches the elastic member. When the pedal is stopped, the elastic member restores the pedal, and the throwing arm is also returned to its original position where the rear side of the sidewall of the throwing arm is stopped by the top side of the trigger arm. Since there is no need to additionally install a motor for driving the throwing arm to restore the position, the invention has the advantages of saving power and environmental protection and can save motor assembly and component costs.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for an availability oriented durability technique for distributed server systems. A server that is an entry point for a message processing stream receives a message from a client device, and in response, generating a unique identifier for the message, and adds an entry in a transaction log that including the message and the unique identifier for the message. The server appends the unique identifier to the message, and transmits the message to a second server positioned downstream from the server in the message processing stream. If the server determines that the message has not been processed through the message processing stream, the server accesses the message from the transaction log, appends the unique identifier to the first message, and re-transmitting the message to the second server positioned downstream from the server in the message processing stream.
