Crushing of roasted Arabica coffee beans

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010
Paper deals with experimental research on the crushing of coffee beans of different kinds under quasi-static compression. The process of the crushing is described in details. It has been shown that there is variability in the crushing strength values.

Effect of grain shape on the agglomeration of polycrystalline thin films

open access: yes, 2006
Grain-boundary grooving is a general phenomenon occurring in all polycrystalline materials at the intersection between the grain-boundary and the interface or free surface. It has been studied theoretically for some time.

Influence of crusher type in the shape of fine crushed aggregate grains

open access: yesRevista IBRACON de Estruturas e Materiais, 2018
Quarries have invested in equipment to increase production and improve the quality of their products, such as vertical shaft impact crushers (VSI). This type of crusher works with autogenous comminution of the material to improve the shape of the coarse ...

Effects of Particle Shape and Packing Density on the Mechanical Performance of Recycled Aggregates for Construction Purposes

open access: yesBuildings, 2023
This paper employs the discrete element method (DEM) to study the mechanical properties of artificial crushed stone. Different grain shapes and gradations are considered, and three types of 3D artificial stone models are generated based on the ...

Quantum Charge Fluctuations in a Superconducting Grain

open access: yes, 2005
We consider charge quantization in a small superconducting grain that is contacted by a normal-metal electrode and is controlled by a capacitively coupled gate. At zero temperature and zero conductance $G$ between the grain and the electrode, the charge $

Interpreting the effects of DNA polymerase variants at the structural level

open access: yesMolecular 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 ...

C2D Spitzer-IRS spectra of disks around T Tauri stars: I. Silicate emission and grain growth [PDF]

open access: yes, 2005
Infrared ~5--35 um spectra for 40 solar-mass T Tauri stars and 7 intermediate-mass Herbig Ae stars with circumstellar disks were obtained using the Spitzer Space Telescope as part of the c2d IRS survey.

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

open access: yesFEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Effect of grain boundary on the buckling of graphene nanoribbons

open access: yes, 2012
The buckling of graphene nano-ribbons containing a grain boundary is studied using atomistic simulations where free and supported boundary conditions are invoked.

Coulomb Blockade Oscillations of Conductance at Finite Energy Level Spacing in a Quantum Dot [PDF]

open access: yes, 2004
We find an analytical expression for the conductance of a single electron transistor in the regime when temperature, level spacing, and charging energy of a grain are all of the same order. We consider the model of equidistant energy levels in a grain in
