Abstract: The present disclosure provides a method for evaluating a geological storage amount of carbon dioxide (CO2) in a fractured-vuggy carbonate reservoir, including: performing image identification on a three-dimensional scanned image of a rock sample to obtain identified rock information; inputting the identified rock information to a computational fluid dynamics-based numerical simulator for constructing a fractured-vuggy rock structure model, and obtaining geometric topological information of the rock sample based on the fractured-vuggy rock structure model; inputting relevant parameters of the rock sample and the geometric topological information to a multi-scale multi-phase flow numerical model for numerical simulation of multi-phase flow migration of CO2 in models of different scales and obtaining a multi-scale numerical simulation result; and calculating a multi-scale CO2 storage efficiency based on the multi-scale numerical simulation result.

Abstract: A packing device for an adsorption device is disclosed. The packing device includes a heating support frame, a packing layer support and a plurality of packing cells. The packing layer support is horizontally extended and arranged in a length direction of the heating support frame, and grooves are alternately provided on both sides of the packing layer support. A clamping slot corresponding to each groove is provided on one side of each packing cell, the packing cell is clamped to the packing layer support through the clamping slot, and one side of the packing cell is in contact with an inner wall of the heating support frame.

Abstract: The invention provides a method of applying rat tail collagen in the field of cosmetics. Compared with the conventional collagen on the market currently, in addition to having the characteristics of general collagen, the rat tail collagen still has the advantages of a stable triple helix structure, high collagen activity, low immunogenicity, controllable quality of the source and high biological safety, so radiation sterilization which lowers the biological activity of the collagen may not be needed. As determined from the experiment, the rat tail collagen prepared by the technical solution provided by the present invention has the properties of whitening skin, inhibiting melanin synthesis, resisting oxidation and allergy, repairing hormone skin and removing acne. The method provided by the present invention also overcomes the technical drawbacks that the collagen-contained cosmetics usually have.

Abstract: The present invention relates to the preparation and use of a cell cryopreservation formulation convenient for clinical use. In particular, provided is a cell cryopreservation (freezing) formulation, comprising: (1) a cell; (2) a cryopreservation diluent; the cryopreservation diluent comprising: an aqueous solution of sodium chloride, protective proteins, and dimethyl sulfoxide. The invention also relates to a corresponding cell resuscitation method. The invention adopts a no-wash cryopreservation solution for preparation of a cell frozen preparation, and the cell resuscitation and dilution for clinical use can be carried out by a simple formulating operation.

Abstract: A mixed reality system and method for determining spatial positions of dental instruments without having a fixed intra oral reference point is disclosed. An intra-oral image sensor-based positioning device including at least two cameras is provided to sense and track the movements of dental instruments being used. The three-dimensional coordinates relating to the movement and orientation of the dental instruments are obtained for real time or delayed use in a mixed reality environment.

Abstract: A BM23 peptide is obtained by mutating and modifying BMP-2. The BM23 peptide improves stability and duration of in-vivo efficacy relative to BMP-2, has an activity of promoting the differentiation of bone marrow mesenchymal stem cells into chondrocytes and promoting the proliferation of chondrocytes and can be used for repairing cartilage and/or treating osteoarthritis.

Abstract: A maxillary tuberosity holding bite block is disclosed. The maxillary tuberosity holding bite block includes a curved tail that embraces a patient's maxillary tuberosity, which allows the bite block to hold the patient's jaws in a stable position, regardless of whether or not the patient has edentulous jaws. Moreover, the maxillary tuberosity holding bite block may serve as a carrier for sensors and endoscopes so it may serve as an intra-oral sensor-based positioning and navigation device that sense and track the movement and position of sensor-equipped surgical instruments.
