Strong, constitutive plant promoters are provided, referred herein to as AA6 promoters, which remain strong and constitutive under biotic and / or abiotic stress conditions. Also provided are transgenic cells and organisms, especially plant cell and plants, comprising an AA6 promoter and methods for expressing nucleic acid sequences in cells and organisms using AA6 promoters.

The invention provides the nucleotide sequence and amino acid sequences of the parthenogenesis gene of Taraxacum as well as (functional) homologues, fragments and variants thereof, which provides parthenogenesis as a part of apomixis. Also parthenogenetic plants and methods for making these are provided, as are molecular markers and methods of using these.

The present invention provides a dual-organic phase flotation separation system containing ionic liquid and a method for removing rare earth elements in spent fuel. The system includes: the first organic phase (also called the upper phase or phase 1), including the following The basic solvent phase of one or more compositions in the above material: multi-chain organic alkanes solvent, organic ester solvent, oleic acid fatty acid solvent and naphthenic acid solvent; ), which is a composite phase of the first type of ionic liquid and the second type of ionic liquid, the first type of ionic liquid is an imidazole ionic liquid, and the second type of ionic liquid is selected from the group consisting of pyridines, pyrroles, piperidines, Quaternary ammonium or its functionalized ionic liquid. The direct all-solid-state separation of rare earth elements from spent fuel can be effectively achieved through a multi-stage serial differential flotation process.

The invention discloses a distribution box, and relates to the technical field of power equipment. The technical key points are as follows: the distribution box comprises a box body, a box door and anelectric appliance fixing plate which is installed in the box body and equipped with electric appliance elements; and a plurality of heat dissipation holes are formed in the box body. The distribution box is characterized in that the inner wall of a top plate of the box body is fixedly connected with a soft magnet; a permanent magnet is attracted to the side, away from the top plate of the box body, of the soft magnet; a compression spring in a compressed state is connected between the soft magnet and the permanent magnet; an insulating layer is arranged on the side, away from the soft magnet, of the permanent magnet; an insulating insert perpendicular to the insulating layer is arranged on the insulating layer; a left contact and a right contact which are connected with a bus are arranged below the insulating insert; and the left contact and the right contact elastically abut against each other and are symmetrically arranged with the insulating insert as a plane of symmetry. The distribution box has the advantage that the power can be cut off in time in case of fire and the risk that open fire diffuses along a wire is reduced.

The invention provides a vehicle epidemic prevention and control method based on entry return and domestic wandering. The present invention collects the vehicle passing information of the expressway site through the expressway site collection module, and wirelessly transmits it to the central server; the central server combines the vehicle license plate information of each expressway site at each collection time to construct the track data set of the target vehicle expressway site; The track data set of the expressway station of the target vehicle is searched and constructed in a centralized manner, and the track data set of the expressway border station of the target vehicle is searched and constructed, and the direction of the expressway and the station number of the expressway border station of the target vehicle are further judged; The wandering illegal model provides early warning; the invention does not need to install any hardware equipment on the inspected vehicle, fully utilizes the existing data resources and checkpoint resources on the road, and provides an efficient and reliable Vehicle epidemic prevention and control methods.

The invention discloses an operation robot system for performing laser resection and refrigeration on tumor tissues. The operation robot system comprises a computer system, a cryogenic system and an operation robot system, wherein an operation mechanical arm of the operation robot system is controlled by a computer mainframe to move freely; a cryogenic transmission tube of the cryogenic generator, laser fibers of a laser and a tail end image detector electrically connected with the computer mainframe extend into multiple arm sections sequentially and respectively to reach the tail end of the operation mechanical arm; cryogenic fluid is communicated with the cryogenic generator by virtue of a cryogenic solenoid valve; the tail end image detector is used for receiving relevant images and transmitting the relevant images to the computer mainframe by virtue of a data transmission line, and simultaneously, the relevant images are displayed on a display screen; the computer mainframe controls an operation robot mainframe and orders the movement, refrigeration and resection work in different directions of the operation mechanical arm; and as a doctor controls the mechanical arm to implement a whole operation in a non contact way, the tumor tissues are subjected to refrigeration and resection simultaneously, and the whole process is visualized, the precision and digitalization of the tumor resection are ensured, the risk of tumor spread is low, and the mechanical trauma is small.
