ECM-transmitted shear stress induces apoptotic cell extrusion in early breast gland development

open access: yesFrontiers in Cell and Developmental Biology, 2022
Epithelial cells of human breast glands are exposed to various mechanical ECM stresses that regulate tissue development and homeostasis. Mechanoadaptation of breast gland tissue to ECM-transmitted shear stress remained poorly investigated due to the lack

Rheology and ultrasonic properties of Pt57.5Ni5.3Cu14.7P22.5 liquid [PDF]

open access: yes, 2007
The equilibrium and nonequilibrium viscosity and isoconfigurational shear modulus of Pt57.5Ni5.3Cu14.7P22.5 supercooled liquid are evaluated using continuous–strain-rate compression experiments and ultrasonic measurements. By means of a thermodynamically-

Non-Newtonian Rheology of Igneous Melts at High Stresses and Strain Rates: Experimental Results for Rhyolite, Andesite, Basalt, and Nephelinite [PDF]

open access: yes, 1990
The stress-strain rate relationships of four silicate melt compositions (high-silica rhyolite, andesite, tholeiitic basalt, and nephelinite) have been studied using the fiber elongation method.

Evaluation of post-liquefaction volumetric strain of reconstituted samples based on soil compressibility

open access: yesSoils and Foundations, 2021
In this study, we performed undrained cyclic–torsional–shear tests on clean and silty sands to examine post-liquefaction volumetric strain. Accordingly, we proposed a novel density index—ultimate volumetric strain—to evaluate the density of clean sand ...

Examination and analysis of the water tightness of watertight doors in nuclear facilities (Water tightness of the watertight doors beyond design conditions)

open access: yesNihon Kikai Gakkai ronbunshu, 2020
A test on the water tightness performance of watertight doors was conducted to obtain knowledge on the fragility beyond design conditions. The performance test was conducted on three types of standard single-swinging watertight doors used for nuclear ...

Enhancing the CPT correlation with the small strain shear stiffness of sands

open access: yesAin Shams Engineering Journal, 2017
The cone penetration test (CPT) is a valuable geotechnical insitu test. Yet, the CPT correlations with the small strain shear modulus and seismic shear wave velocity still need more research to enhance their accuracy.

Design of horizontal shear strain instrument for co-estimation of soil stress-strain [PDF]

open access: yesE3S Web of Conferences, 2020
This study aimed to design and fabricate the horizontal shear strain transducer (HST) for measuring the soil strain under the agricultural machinery traffic by using a rotary potentiometer which was an angular strain change detector.

Strain Hardening in Graphene Foams under Shear [PDF]

open access: yesACS Omega, 2021
Strain hardening is an important issue for the design and application of materials. The strain hardening of graphene foams has been widely observed but poorly understood. Here, by adopting the coarse-grained molecular dynamics method, we systematically investigated the microscopic mechanism and influencing factors of strain hardening and related ...
