Abstract: Disclosed are a method and a device for identifying full-section excavation parameters of large-section tunnel with broken surrounding rock, which is capable of solving the problem of inaccurate arrangement of blasting hole points in tunnel excavation engineering, including following steps: establishing a three-dimensional finite element model based on a blasting section design of a tunnel; performing a simulation with the three-dimensional finite element model based on blasting design parameters to obtain blasting quality parameters; selecting a group closest to a preset quality parameter from multiple groups of the blasting design parameters as target blasting design parameters, wherein the preset quality parameter is an acceptance grade standard of the tunnel; obtaining first thermal imaging information of a first hot spot of a surface to be blasted; calibrating actual hole spacing parameters based on the first thermal imaging information and the target blasting design parameters.

Abstract: A Sanzan gum-containing stabilizer for a compound protein beverage, and a use and compound protein beverage are provided. The Sanzan gum-containing stabilizer for a compound protein beverage provided in the present disclosure includes Sanzan gum and mono-and diglycerides of fatty acids, where a mass ratio of the Sanzan gum to the mono- and diglycerides of fatty acids is (50-75):100. A compound protein beverage prepared with the Sanzan gum-containing stabilizer for a compound protein beverage provided in the present disclosure has a sensory score of 80 or more, and the Sanzan gum-containing stabilizer can significantly reduce oil slicks at a top and precipitates at a bottom of the beverage and has a better stabilizing effect than xanthan gum and carrageenan systems.

Abstract: A frequency-adjustable water dripping device. The water dripping device includes a U-shaped magnetic conductive cup, a printed circuit board (PCB), a magnetic field generating device, a water containing cavity, and a water outlet, where the U-shaped magnetic conductive cup is connected to the magnetic field generating device, and the magnetic field generating device is connected to the PCB. When alternating current signals with different frequencies are input into the PCB and sent to the magnetic field generating device, a volume of the water containing cavity is changed by means of a magnetic field generated by the magnetic field generating device, such that different water dripping effects are generated. According to the frequency-adjustable water dripping device, the volume of the water containing cavity is changed by means of the generated magnetic field, such that different water dripping effects are generated.

Abstract: The present invention relates to preparation of a plant-based fermented dairy alternative where the plant-based substrate is treated with an endopeptidase, preferably a specific endopeptidase selected from trypsin-like endopeptidase, lysine-specific endopeptidase or glutamyl-specific endo-peptidase. Further preferred is the combination with a phospholipase.
