In this study, the authors hypothesized that in acute ischemic strokes, more permeable intracranial arterial thrombi (as opposed to less permeable thrombi) could be associated with better clinical outcomes and improved response to intra-arterial therapy. The authors examined the attenuation increase on computed tomographic angiography (CTA) and void fraction, using combination of noncontrast co...

The void index is a relative quantity measuring the position of the current void ratio of a clay against the void ratios of the clay at two specific vertical effective stresses (i.e., σ v ′ = 100 kPa and σ v ′ =1000 kPa). Based on this concept, a simple systematic tool is proposed for estimating the compression behaviour of reconstituted clays over a wide range of stresses and water contents. F...

For the safe extraction of methane from hydrate reservoirs, modeling mechanical behavior hydrate-bearing soil properly is crucial in order to enable designers analysis hydrate-dissociation-induced geotechnical failures. Hydrate morphology one major factors affecting containing hydrate. This paper presents a new constitutive model for sand (MHBS) using equivalent granular void ratio as state var...
