This paper proposes a framework for relating electrical conductivity of cement-treated marine clay to its strength.The feasibility of relating conductivity to strength is first examined by measuring the two quantities over a range of water-cement and soil-cement ratios as well as curing periods.The results indicate that, within a limited curing per
Abstract Background Gut microbiota plays important roles in host animal metabolism, homeostasis and environmental adaptation.However, the interplay between the gut microbiome and urochordate ascidian, the most closet relative of vertebrate, remains less explored.In this study, we characterized the gut microbial communities of urochordate ascidian (
In recent years, underwater shield tunnels are being developed according to large-scale sections.The problems of large buried depth and high water pressure have posed major challenges to the safety of segmented structures.The load-bearing capacity and damage of segmented structures under high water pressure features have always attracted attention.
