Stability of infinite unsaturated soil slopes with tensile strength cut-off

open access: yesYantu gongcheng xuebao, 2020
Based on the Fredlund strength theory, a nonlinear strength criterion for unsaturated soils is proposed. The tensile strength envelope of the Fredlund strength theory as a result of extrapolation of compressive tests into the tensile regime is partially ...

Mechanical properties of sandstone and prediction model of shear deformation band under true triaxial unloading conditions

open access: yesMeitan xuebao, 2023
The intermediate principal stress and unloading have an important influence on the shear failure characteristics of rock. Based on the multifunctional true triaxial fluid-structure interaction test system, the loading and unloading failure tests of ...

An aerodynamic load criterion for airships [PDF]

open access: yes, 1975
A simple aerodynamic bending moment envelope is derived for conventionally shaped airships. This criterion is intended to be used, much like the Naval Architect's standard wave, for preliminary estimates of longitudinal strength requirements.

Financial Burden Associated With Hospitalisation Among Families of Childhood Brain Tumours in Australia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Quantum Cloning of Continuous Variable Entangled States [PDF]

open access: yes, 2007
We consider the quantum cloning of continuous variable entangled states. This is achieved by introducing two symmetric entanglement cloning machines (or e-cloners): a local e-cloner and a global e-cloner; where we look at the preservation of entanglement

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Bimodal strength criterion and constitutive model for cemented sand and gravel

open access: yesYantu gongcheng xuebao
In order to explore the intricate mechanical properties of the cemented sand and gravel (CSG), large-scale triaxial shear tests are conducted on the specimens with varying confining pressures and gel contents.

Formulation of Anisotropic Strength Criterion for Geotechnical Materials

open access: yesAdvances in Civil Engineering, 2020
A new nonlinear unified strength (NUS) criterion is obtained based on the spatially mobilized plane (SMP) criterion and Mises criterion. New criterion is a series of smooth curves between SMP curved triangle and Mises circle in the π plane and thereby ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Mean-field cooperativity in chemical kinetics

open access: yes, 2011
We consider cooperative reactions and we study the effects of the interaction strength among the system components on the reaction rate, hence realizing a connection between microscopic and macroscopic observables.
