Abstract: Tongji-1 lunar soil simulant (TJ-1 for short) was recently invented by Tongji University, China. It could be used to construct testing ground in the preparatory impact tests of lunar landers under the extremely adverse ...

Abstract: Experiments were carried out using a dynamic hollow-cylinder apparatus (HCA) to investigate the effects of stress paths and principal stress rotations experienced during a simple vertical excavation on the element-scale ...

Abstract: A seven-year-old bioretention cell in Silver Spring, Maryland was surveyed for vegetation and media characteristics 11 months after last maintenance. Volunteer plants constituted more than half of the cell vegetation.

Abstract: The three-dimensional discrete element method (DEM) is employed to investigate the macro- and microscopic mechanical behaviors of unsaturated silt subjected to one-dimensional (K0) and constant stress ratio loadings. A DEM ...

Abstract: The dynamic behaviors of a pinned–pinned spinning exponentially functionally graded shaft with unbalanced loads are investigated. The shaft is simulated in the Rayleigh beam model considering rotary inertia and gyroscopic ...

Abstract: AbstractRisk assessment of undersea tunnel collapse is very important for tunnel construction safety. Because the existing methods cannot guarantee the accuracy and authenticity of relevant on-site data, they limit the ...

Abstract: Central venous catheter (CVC) related thrombosis is a major cause of CVC dysfunction in patients under hemodialysis. The aim of our study was to investigate the impact of CVC insertion on hemodynamics in the central veins ...
