Abstract: A sample mounting device for direct tensile test of rock mass is provided, which includes a first positioning stage, a second positioning stage, a first support piece, a second support piece, and a screw drive mechanism. The second positioning stage is arranged above the first positioning stage and capable of moving up and down, and cushion blocks for gluing with the rock mass are coaxially and detachably arranged at opposite ends of the first positioning stage and the second positioning stage, and a rock mass mounting area is formed between the two cushion blocks. A screw of the screw drive mechanism includes a first thread segment and a second thread segment with opposite thread directions. The first support piece is connected with the first thread segment through a nut seat, and the second support piece is connected with the second thread segment through a nut seat.

Abstract: An integrally-formed three-dimensional (3D) bio-printing system capable of alternate feeding of multiple materials, comprising: an optical imaging unit and a light path conversion unit, wherein the optical imaging unit comprises an image processing unit and a projection unit, the image processing unit segmenting a 3D modeling graphic of a printed subject to form image information, the projection unit converting the image information into one or more optical images, and the light path conversion unit projects the imaged light paths into bio-ink that can be cured by light, so that the projected image can cure the bio-ink by means of the focus of light.

Abstract: The purpose of the present invention is to provide a light control agent and explore its application, and is expected to improve the tissue binding force and convenience of the existing biological glue material by providing a new reagent or material for biological damage or homeostasis. In one of embodiment, this invention provides an agent for repairing biological damage or homeostasis, wherein the agent comprises a natural biological macromolecule modified by the photo-responsive cross-linking group.

Abstract: An exemplary solid waste treatment system can be provided which can include a storage device, an intelligent aerobic fermentation treatment device, a retaining wall-type fermentation area, and an aeration platform. The intelligent aerobic fermentation treatment device can include a traveling trolley, a lifting mechanism, a material pick-and-place mechanism, and a traveling bridge linearly moving in a direction away from the storage device towards the retaining wall-type fermentation area. The aeration platform can be arranged at the bottom of the retaining wall-type fermentation area. The traveling trolley linearly can move on the traveling bridge in a direction perpendicular to the direction away from the storage device towards the retaining wall-type fermentation area. The lifting mechanism can be mounted on the traveling trolley. The material pick-and-place mechanism can be suspended on the lifting mechanism to be raised and lowered in step with the raising and lowering of the lifting mechanism.

Abstract: The apparatus for cell or tissue culture comprises a base plate (1), an intermediate face (2) and a top plate (3). The intermediate face (2) is removably sandwiched between the base plate (1) and the top plate (3). The base plate (1) has a circumferential wall (13), a base (14) and a top wall (16). The top wall (16) of the base plate (1) comprises a plurality of recesses (12) arranged in n lines, wherein n is an integer from 1 to about 25. Each line of recesses (12) ranges from a first recess to a last recess. Each recess has a circumferential recess wall (15), which has one recess inlet and one recess outlet (40, 41). The circumferential wall (13) comprises a number of 2 n ports (11). Each port (11) is coupled to a single line of recesses (12).

Abstract: Communication networks and associated methods are disclosed for dynamically defining service triggers. Responsive to receiving a session initiation message for a session, an application server defines one or more subsequent service triggers for a service provided by the application server for the session. The subsequent service triggers identify messages or conditions for the session of which the application server desires to be notified. The application server then transmits the subsequent service triggers to a session control function that is setting up or maintaining the session. The session control function then receives a subsequent message for the session. The session control function processes the subsequent message and the subsequent service triggers to determine whether to transmit the subsequent message to the application server.
