Abstract: The invention provides a calculation method for dike breach development process, which relates to the field of flood disaster prevention. In this method, the influence of hydrodynamic on the development rate of the breach is considered, and the unit discharge of the breach is taken as the main parameter. The parameter expression between the hydrodynamic factors and the development process of the breach is established for both lateral widening and vertical downcutting. According to the invention, the whole development process of dike breach can be calculated with only a few parameters, and the main parameter unit discharge can be directly obtained by the discharge formula of broad crested weir. As the calculation incorporating as much physical mechanism as possible and simple calculation procedure, the method has high practicability, good repeatability and scientificity.

Abstract: A recyclable inclination measuring device includes measuring units arranged in a linear array during installation, and two adjacent measuring units are eccentrically hinged by a joint; during the measurement, measuring units are arranged in a Z shape in the measuring tube, the inner wall of the measuring tube is closely attached to the joint, and measuring units extending out of the measuring tube are folded and arranged. the present invention adopts a recyclable inclination measuring device with the above structure, during the measurement, it is placed in the measuring tube, which can be arranged in a Z shape under the action of gravity, and then it can be measured with the synchronous rotation of the measuring tube, when it is recovered, it only needs to be pulled out, which reduces the difficulty of recovery and improves the recovery efficiency.

Abstract: A barrier structure for bearing a high-energy impact and construction method thereof are provided. The barrier structure includes a supporting pile array arranged between two opposite mountain slope surfaces. The supporting pile array is arranged in a straight line and includes two or more supporting piles. The two or more supporting piles are fixed at a lower part of a mountain. A barrier net is connected to the two or more supporting piles. The barrier net passes through the supporting pile array and extends to the two opposite mountain slope surfaces. The barrier net is fixed on the two opposite mountain slope surfaces. Pull plates are disposed on the two opposite mountain slope surfaces, and one side of each of the pull plates is fixed to a corresponding slope surface of the two opposite mountain slope surfaces through reverse prestressed anchor cables.

Abstract: The present invention provides novel virus vaccines with augmented, e.g., enhanced and/or extended immunogenicity. The virus vaccines of the invention comprise an envelope-bound immunomodulatory protein, e.g., a cytokine, chemokine or costimulatory molecule. The immunomodulatory protein serves as an adjuvant to augment, e.g., enhance or extend the immunogenicity of the virus vaccine, thereby augmenting, e.g., enhancing or extending immune response to the virus when administered to a subject.
