Numerical simulation of direct shear test of sand considering rotational impedance
Shuili Shuiyun Gongcheng Xuebao, 2021 A series of sand direct shear numerical simulation tests were performed using the discrete element method, so as to investigate the inherent relation of meso-mechanics between the particle’s rotation-resistant capacity and the interaction of sands and ...

Interface shear characteristics of dredger fill and concrete using large size direct shear test
International Journal of Geo-Engineering, 2018 A large-size direct shear test was conducted to test the interface of dredger fill and concrete. The effect that concrete strength and the density of dredger fill have on the properties of interface is then analyzed.

Characterization of peak shear strength of rough rock joints using limited displacement multi-stage direct shear (LDMDS) tests [PDF]
E3S Web of Conferences, 2019 Current standard direct shear test methods for rock joints do not account for damage to the specimens' asperity profiles; tests require shearing of a single specimen to large displacements under successive normal stresses (the multistage test), or the ...

A COMPARATIVE STUDY ON SHEAR STRENGTH OF MARINE CLAYS BY DIRECT SHEAR AND DIRECT SIMPLE SHEAR TESTS
Doboku Gakkai Ronbunshu, 1998 九州の有明粘土およびノルウェーの Drammen 粘土について, 三笠式一面せん断試験機とNGI型単純せん断試験機による一連の比較実験を行った. 実験は, 不撹乱試料をその有効土被り圧で再圧縮した後せん断に供するものと人工的に作成した過圧密粘土について実施した. その結果, 下記のような結論が得られた. 1) 一面せん断試験は単純せん断試験よりも高い剛性とせん断強度を与える, 2) この違いは主としてせん断機構と載荷速度の違いによるものと考えられ二つの要因に対する補正係数を導いた, 3) この係数を一面せん断強度に乗じた補正一面せん断強度は, 単純せん断強度と良い一致を示した, 4) しかし人工的に作成した過圧密粘土の試験結果についてはこの補正は適用できない.

Metastatic niche shaped by host factors influences disseminated cancer cell fate
FEBS Letters, EarlyView.Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer
Molecular Oncology, EarlyView.Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Molecular Oncology, EarlyView.We established the avian chorioallantoic membrane (CAM) assay as a scalable in vivo model for studying circulating tumor cells (CTCs). Human gastrointestinal tumors spontaneously released genetically validated CTCs that were detected across multiple platforms, demonstrating that the CAM model provides an accessible tool for investigating early cancer ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
