The present invention proposes a MABR membrane assembly, a MABR reactor, a MABR reactor operation method and a MABR biofilm optimization control method, which adopts a cross-flow working mode between horizontal membrane filaments and water flow to improve the mass transfer efficiency of the matrix and metabolites in the MABR biofilm; the composite structure membrane assembly is used to promote the complementarity and symbiosis of various microorganisms such as carbon removal aerobic bacteria, nitrifying bacteria, denitrifying bacteria and anaerobic ammonia oxidizing bacteria; different areas such as MABR membrane reaction area, pre-reaction area and water distribution and gas distribution area are constructed in the same reactor to complete short-range nitrification or partial short-range nitrification reaction, short-range denitrification reaction and anaerobic ammonia oxidation reaction respectively, so as to achieve efficient biological denitrification of sewage with low carbon-nitrogen ratio in a single-stage MABR reactor. At the same time, the optimization control method of the MABR biofilm solves the problems that the overly thick biofilm in the MABR reactor is not easy to be effectively washed, and the fixed gas washing frequency and intensity are difficult to simultaneously adapt to the biofilm washing and film removal requirements of membrane filaments in different parts.

The invention discloses a dendroctonus valerieus pheromone temperature response electrospun nanofiber as well as a preparation method and a lure thereof. The preparation method comprises the following steps: A, mixing dichloromethane and paraffin to obtain a solution A; b, adding polyhydroxybutyrate and pheromone 3-carene in the solution A, and stirring and dissolving the polyhydroxybutyrate and the pheromone 3-carene in the solution A to obtain a solution B; and C, carrying out electrostatic spinning on the solution B to obtain the temperature response electrospun nanofiber of the dendroctonus valerieus pheromone. The paraffin is added into the formula aiming at the rhythm that the dendroctonus valerieus is going out in the daytime, intelligent luring can be performed, the paraffin is dissolved at high temperature in the daytime so as to release the attractant in a concentrated manner, the temperature is reduced at night, and the paraffin releases the attractant in a closed manner, so that the use efficiency of the luring core is improved, and the woodland application time is prolonged; the effect persistence is improved while the attraction efficiency is improved.

This invention relates to the field of needle-free injector technology, and in particular to an apparatus and method for needle-free injection of local anesthetics into the dermis for infiltration anesthesia. The apparatus includes a receiving space for containing the anesthetic solution; the injection pressure is 14-21 MPa. This invention allows for the design of different needle-free injectors to address the physiological differences in the dermis between men and women, ensuring precise intradermal injection of the anesthetic solution and avoiding entry into the muscle layer. Furthermore, it results in less pain during injection and a longer duration of effect from the onset and exhaustion of the local anesthetic.

The invention provides functional rare earth-containing growth factor gel and a preparation method thereof, the gel is prepared from a matrix, NGF and rare earth-manganese bimetallic nano-enzyme CeMn NP-PEG according to a mass ratio of 10: 1: (0.2-1), the CeMn NP-PEG is CeMn NP with the surface modified with PEG, the CeMn NP is prepared from Ce (Ac) 3. NH2O and Mn (Ac) 3. 4H2O through a sol-gel reaction, and the doping amount of Ce is 20 wt%-50 wt%. According to the gel, CeMn NP-PEG, NGF and a matrix are integrated into an integrated functional dressing, the antioxidant function is achieved through the ROS removal effect, a foundation is laid for follow-up achievement of inflammation regulation and control, nerve-blood vessel-epidermis synergistic repairing and healing promoting effects, and the gel is expected to meet the clinical requirements for rapid and high-quality healing of common wounds.
