The invention provides a method for preparing a carbon source by reinforcing kitchen waste based on a Fe composite MXene material. According to the method, the Fe composite MXene material is added in the anaerobic fermentation process of the kitchen waste, so that the external electron transfer capability of indigenous bacteria of the kitchen waste can be enhanced by utilizing Fe (III) sites on the surface of the material, the decomposition effect of organic matters in the kitchen waste is improved, and the quality of an organic biological carbon source is improved. Fe (III) on the surface of the material can be reduced by microorganisms to generate Fe (II), and the Fe (II) is oxidized into Fe (III) again when the Fe (II) is in contact with air, so that cyclic utilization of Fe (III) / Fe (II) is realized. The Fe composite MXene material can replace a traditional functional microbial agent and organic matter decomposing enzyme, the fermentation period of the kitchen waste is shortened, the solubility COD of the organic biological carbon source and the volatile organic acid carbon source are improved, and the method has wide application prospects in the aspect of preparing the carbon source from the kitchen waste.

The invention provides a composite additive and application thereof in mammalian cell culture, and relates to the technical field of cell culture, the composite additive comprises a pyrimidine nucleoside precursor, vitamin, amino acid, a TCA circulation intermediate product and metal ions; wherein the deoxyuridine is used as a pyrimidine nucleoside precursor and can promote cell DNA synthesis so as to improve the peak living cell density; pyridoxine hydrochloride and choline chloride synergistically regulate amino acid metabolism and enhance the antibody synthesis efficiency; magnesium is an activating agent of mitochondrial key enzymes such as pyruvate dehydrogenase and citrate synthase and can improve the ATP generation efficiency and provide more energy for antibody synthesis, alpha-ketoglutaric acid optimizes tricarboxylic acid circulation to supply energy, the cell activity in a low-iron environment is guaranteed, finally, multi-channel synergistic interaction is achieved, the cell density and the antibody yield are improved, and the product quality is improved. And the key quality attribute of the antibody is not changed. The technical problem that a culture medium in the prior art cannot coordinate the balance of cell density, antibody yield and charge heterogeneity in a low-iron environment is solved.

The invention relates to the field of obstetrics and gynecology midwifery, in particular to an obstetrics and gynecology midwifery auxiliary device which comprises a midwifery chair, a seat plate is fixedly installed on the upper surface of the midwifery chair, the rear end of the seat plate is rotationally connected with a lying plate through an arranged hinge, and a pushing and pressing mechanism is arranged above the lying plate. The front end of the seat plate is rotationally connected with a foot pad plate through an arranged hinge. Under the condition that a pregnant woman is not suitable for exerting force or does not have autonomous force during childbirth due to diseases, the abdominal wall of the pregnant woman is massaged, pushed and pressed in time through a rolling ball to assist childbirth, and the fetal head can be supported in different directions after being discharged out of the vaginal orifice through the supporting mechanism. The situation that the doctor has more energy to deal with the condition during delivery is affected by the fact that the pad is replaced in time by slightly upwarping the waist of the pregnant woman after the pad is soaked by a large amount of body fluid during delivery of the pregnant woman through the pad replacing mechanism, and therefore judgment of the doctor on the fetus traction position is affected is avoided.

The telegraph pole anti-collision protective sleeve comprises a protective sleeve body movably arranged on a telegraph pole in a sleeving mode, and the bottom of the protective sleeve body is supported on the ground through hydraulic supporting legs; a sealing cavity is formed in the protective sleeve body, a fluid medium is filled in the sealing cavity, and the hydraulic supporting legs are communicated with fluid in the sealing cavity; a flow-limiting pressure relief hole communicated with fluid in the sealing cavity is formed in the protection sleeve body, and a pressure relief film is arranged in the flow-limiting pressure relief hole in a sealing fit mode; the vehicle impact protection sleeve body extrudes the sealing cavity, and a fluid medium in the sealing cavity enters the hydraulic supporting leg. The collision acting force of a vehicle acts on driving force to drive the hydraulic supporting legs to extend to push the protective sleeve body to move, sinking of a vehicle head is effectively restrained, buffering is provided through sinking force of the vehicle head, the hydraulic supporting legs and the protective sleeve body are in a mutual restraining state, the buffering effect is effectively improved, and harm caused by the head effect of the vehicle is reduced.
