The research on the dynamic response and influencing factors of shield tunnel lining under earthquake demonstrates significant engineering value in guiding design antiseismic tunnels. In this paper, a nonlinear finite element model soil-tunnel interaction is established based FLAC difference software, then Mohr–Coulomb elastoplastic plastic damage are used to simulate characteristics soil tunne...

Introduction Emerging hypotheses suggest a causal role for prenatal androgen exposure in some cases of Autism spectrum disorders (ASD). The ratios of the lengths of the bones of the 2nd to the 4th digits (2D:4D) are purported to be markers for prenatal androgen exposure and to be established early in gestation. Ratio of second and fourth digits (2D:4D)  is usually used as a proxy for prenatal t...

Objective- Assessment of the lens anterior – posterior (AP) diameter as compared with the eye globe by ultrasonography in rabbit.   Design- Descriptive study.   Animals- 120 male and female rabbits, two months to four years old, and weighting between 300 to 1500gr.   Procedures- 2D ultrasonography of the eyes was performed and AP diameter of the eyes and lens were measured using Sonosite Tit...

in this paper, the two-dimensional triangular orthogonal functions (2d-tfs) are applied for solving a class of nonlinear two-dimensional volterra integral equations. 2d-tfs method transforms these integral equations into a system of linear algebraic equations. the high accuracy of this method is verified through a numerical example and comparison of the results with the other numerical methods.

In order to study the stability of tunnels under static-dynamic load, a new large-scale model test system was developed. The composed static loading unit, dynamic data acquisition unit and bench, which were specially designed overcome technical problems test, such as control, high-rate strain measurement easy operation. used 3600 × 2500 mm in size larger load disturbance area than tests. It can...
