Numerical Prediction of the Bulk Density of Granular Particles of Different Geometries

open access: yesKONA Powder and Particle Journal, 2014
The Discrete Element Method (DEM) is increasingly used to simulate the motion of granular material in engineering devices. The most widely used shape to model granular particles is the sphere due to its simplicity ...

Combined Influence of Particle Shape and Fabric on the Shear Behaviour of Granular Materials

open access: yesAdvances in Materials Science and Engineering, 2022
The anisotropy feature is an important characteristic of granular materials in natural life and is caused by two facts: the anisotropy feature of particle shape, such as an elongated or flattened shape, and the anisotropy feature of the packing fabric ...

Review of particle physics

open access: yes, 2004
This biennial Review summarizes much of Particle Physics. Using data from previous editions, plus 1726 new measurements from 512 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons.

Influence of Particle Shape on Tortuosity of Non-Spherical Particle Packed Beds

open access: yes, 2022
Tortuosity in packed beds or porous media is of significant interest in many fields, from geoscience to the chemical industry. Tortuosity plays a significant role in the mass transport in porous media, but also in their residual thermal or electric ...

Bedload transport in rivers, size matters but so does shape

open access: yesScientific Reports, 2021
Bedload transport modelling in rivers takes into account the size and density of pebbles to estimate particle mobility, but does not formally consider particle shape.

Single particle crushing tests of coarse grained soil considering size and shape effects

open access: yesYantu gongcheng xuebao
Particle size and shape significantly influence the crushing behaviors of coarse grained soil. In this study, the particle scanning, particle shape analysis, and single particle compression tests on the gravel soils of high filling project of Baihetan ...

Shaping Particles for Ultramicrotomy [PDF]

open access: yesMRS Proceedings, 1991
AbstractA technique for preshaping large particles of reacted glass for ultramicrotomy is described. This technique preserves delicate surface layers and results in more sections per block extending deeper into the sample than other techniques.

Chemotherapy for Spinal Cord Intramedullary Pediatric Low‐Grade Glioma—A Systematic Literature Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.
