Studies on the thermo-mechanical behavior...
An EASY-nLC 1200 system (Thermo Fisher Scientific) was connected online with a mass spectrometer (Orbitrap Exploris 480, Thermo Fisher Scientific) via nano-electrospray source. Peptides were separated using a binary buffer system consisting of buffer A (0.1% formic acid (FA)) and buffer B (...
The judgement matrices of the first-level indicator layer, the second-level indicator layer under surface change, the second-level indicator layer under rock mass structure, the second-level indicator layer under physical properties and the second-level indicator layer under matrix weathering in the ...

We studied the sliding mechanism of the soil-rock slope by using transparent soil techno...
The Young modulus was calculated by iterating it until obtaining a Load-Displacement curve that matches the experimental ones. The first cable net simulated and adjusted to the experimental results was the 200 mm reticle (Fig. 11). After several iterations it was found that for 1 mm thick, ...
