It is well recognised that particle breakage in granular materials affected by stress level, path, initial density, and size distribution (PSD), amongst others. Furthermore, it has been shown a significant influence on the stress-strain behaviour of soils. This paper compares commonly used parameter with grading entropy coordinates. Such coordinates enable for representation any PSD as single p...

Chronic inhalation of environmental particles is associated with pulmonary carcinogenesis. Although the mechanism has not yet been fully elucidated, influx of inflammatory cells, including neutrophils, is suggested to play a major role in this process. Typically, in the particle-exposed lung, influx of neutrophils is accompanied by an accumulation of nitrite. Previous studies indicated that nit...

Coral sand, which is an important filler resource in coastal areas, continuously subjected to repeated waves or traffic loading. In this study, a series of oedometer tests are conducted on coral sand and silica under loading, the results compared. The influence initial density number amplitude loading volumetric deformation, soil stiffness, particle breakage investigated. reveal that deformatio...

Abstract Particle breakage and the corresponding change of morphology are two key factors governing mechanical behavior calcareous sands in offshore geotechnical engineering constructions. To reveal characteristics these factors, oedometer tests on have been performed this study. The materials were sampled from South China Sea with a homogenous composition but different particle size ranges rel...
