Location and chemical composition of microbially induced phosphorus precipitates in anaerobic and aerobic granular sludge [PDF]
, 2012 This work focuses on combined scanning electron microscopy and energy dispersive X-ray analysis (SEM-EDX) applied to granular sludge used for biological treatment of high-strength wastewater effluents. Mineral precipitation is shown to occur in the core

Micromechanics of Liquefaction in Granular Materials [PDF]
Physical Review Applied, 2018 A discrete element method (DEM) implementation is developed to study the micromechanics of liquefaction in granular materials. In a liquefaction event, the pore water acts as a cushion between the grains, reducing the contact and friction forces and the overall soil strength.

Coupling between rotational and translational motions of a vibrated polygonal disk
New Journal of Physics, 2020 We investigate experimentally the dynamics of a single polygonal disk (regular n -gon with 3 ⩽ n ⩽ 8) confined in a closed container under vertical vibrations against gravity.

Microstructural anisotropy as the origin of dilatancy [PDF]
EPJ Web of ConferencesDilation in sheared granular materials has been widely observed, yet its micromechanical origins remain debated. Using discrete element method (DEM) simulations of slow granular flows, we find that grain rearrangements occur intermittently, alternating ...

Remarks on Constitutive Modeling of Granular Materials
Eng, 2023 In this paper, we provide a brief overview of certain fundamental concepts which can be used to derive constitutive relations for the stress tensor of granular materials. These include concepts such as dilatancy, cohesion, yield criterion, shear banding,

Interpreting the effects of DNA polymerase variants at the structural level
Molecular Oncology, EarlyView.Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Numerical simulation of cementitious granular materials
Science and Engineering of Composite Materials, 2012 A new numerical approach was developed to study the mechanical properties of cementitious granular materials. At first, an ellipsoid based method was developed to generate aggregate particles of arbitrary shape.
