Abstract: The present invention discloses a pesticide composition for controlling wheat crown rot, comprising prothioconazole and imazalil, and the mass ratio of the prothioconazole to the imazalil is (10-20):1, 1:1 or 1:(10-20). Compared with a single pesticide, the composition of the present invention has an obvious synergistic effect on wheat crown rot, obviously improves the control effect and significantly reduces the pesticide cost; can slow down the resistance of wheat crown rot to the pesticide and prolong the service life of the pesticide; has both quick acting effect and long acting effect on wheat crown rot; can greatly reduce the field application amount and effectively reduce environmental pollution and pesticide residues; and reduces toxicity to other non-target organisms.

Abstract: The present disclosure discloses a media information presentation method performed at a computer server communicatively connected to a plurality of terminals associated with a social networking platform. The method includes: receiving a plurality of media information operation messages, each message indicating an operation performed on a piece of advertisement by one of a first group of users; deriving a second group of users that are direct connections of the first group of users; collecting, from the media information operation messages, statistics on operation statistical data of the second group of users; and receiving a media information obtaining request from a respective user of the second group of users at a terminal; in response to the request, identifying a plurality of pieces of advertisement corresponding to the respective user; sorting them according to their corresponding operation weights; and returning, to the terminal, top L pieces of advertisement in the descending order.

Abstract: Interface circuitry of an apparatus receives a first service data packet that includes at least first information for a first multimedia presentation frame and second information for a second multimedia presentation frame. Processing circuitry of the apparatus stores the first information and the second information in different rows having different row number in a service data table. Then the processing circuitry determines, from a preset database, first material data for the first multimedia presentation frame and second material data for the multimedia presentation frame based on material configuration information in the first service data packet. Further the processing circuitry associates the first material data and the second material data in a material data table with different row numbers in the service data table and generates first multimedia service data corresponding to the first service data packet based on the association between the service data table and the material data table.

Abstract: The present disclosure discloses a media information presentation method performed at a computer server that is communicatively connected to a plurality of terminals. The server receives at least one media information operation message; determines a first user and media information corresponding to each media information operation message, and an operation performed by the first user on the media information, to generate log data; obtains a social relationship chain of each first user included in the log data; collects statistics on operation statistical data of the second user according to the log data; and receives a media information obtaining request of a third user. The server then selects, when operation statistical data of the third user is found from the operation statistical data of the second user, at least one piece of media information from the operation statistical data of the third user, and returns it to the second user.

Abstract: A centrifugal switching device of a single-phase induction motor includes a centrifuge and pressure switches. The centrifuge includes a centrifugal sleeve, a centrifugal base, shaft coupling blocks, and a spring. The spring is directly fitted on the centrifugal base. Under a centrifugal force generated by the rotation of the motor, shaft coupling blocks I and II slide axially against an axial force of the spring, thus forcing an axial end surface of the centrifugal sleeve to be separated from contacts of the pressure switches, such that a starting winding of a stator ferrite-core coil of the single-phase induction motor is disconnected and a heater is turned on. The shaft coupling blocks I and II adopt a design with round transition, central sliding contact, and smooth rotation, thereby achieving a simple structure, convenient mounting, and safety usage.
