Mark‐recapture studies using fluorochrome dyes are a valuable approach for validating the age determination of fish, yet the optimal chemical marker and its dosage for adult European flounder (Platichthys flesus Linnaeus, 1758) remain unclear. We assessed the effectiveness of tetracycline hydrochloride and calcein at different concentrations for ...

A simple permanent deformation model of rockfill materials
Existing experimental results have shown that using a semi-log linear relationship between the permanent volumetric strain and cyclic number underestimates the volumetric deformation of rockfill materials with a large cyclic number, and that the error increases with the confining pressure.

Seismic reliability analysis of high earth-rockfill dams based on deformation control criteria
The reliability-based design (RBD) is one of the most crucial measures to study and guarantee geotechnical engineering safety. Through quantitative analysis of uncertainty in earth-rockfill dam engineering, the failure probability can be evaluated and ...
