The tensile strength of compressed dust samples and the catastrophic disruption threshold of pre-planetary matter [PDF]
, 2020 During the planetary formation process, mutual collisions among planetesimals take place, making an impact on their porosity evolution. The outcome of these collisions depends, among other parameters, on the tensile strength of the colliding objects.

Evaluation of the use of steelmaking slag as an aggregate in concrete mix: A factorial design approach [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2017 Slag is investigated towards its potential use as an aggregate in concrete mix production. Full factorial design methodology is applied to study the effect of two process input variables, namely: slag as coarse aggregate and slag as medium aggregate on ...

Compressibility, capacitance and ground state energy fluctuations in a weakly interacting quantum dot [PDF]
Phys. Rev. B 55, 5297 (1997)., 1996 We study the effect of electron-electron (e-e) interactions on compressibility, capacitance and inverse compressibility of electrons in a quantum dot or a small metallic grain. The calculation is performed in the random-phase approximation. As expected, the ensemble-averaged compressibility and capacitance decreases as a function of the interaction ...

The Strength of Compressed Tablets
Journal of Pharmacy and Pharmacology, 1961 Abstract Examination of the fracture of tablets in a strength test has revealed two types of failure. Where the interparticulate bond is strong, fracture occurs across the grains and the strength of tablet is a simple function of the particle size.

Static compression of porous dust aggregates [PDF]
, 2013 Context: In protoplanetary disks, dust grains coagulate with each other and grow to form aggregates. As these aggregates grow by coagulation, their filling factor \phi decreases down to \phi << 1. However, comets, the remnants of these early planetesimals, have \phi ~ 0.1.
