Hangman’s fracture vs hanged-man’s fracture vs hangee’s fracture [PDF]
Acta Neurochirurgica, 2013 not necessarily a male. The conventional name of “hangman’s fracture”, therefore, should be “hanged-person’s fracture”. Accordingly, we suggest that a more suitable terminology for the so-called “hangman’s fracture” may be the “hangee’s fracture”.

Hydraulic fracturing in cells and tissues: fracking meets cell biology [PDF]
, 2017 The animal body is fundamentally made of water. A small fraction of this water is freely flowing in blood and lymph, but most of it is trapped in hydrogels such as the extracellular matrix (ECM), the cytoskeleton, and chromatin.

Fem Analysis of Proppant Sticking in Rock Cracks
Archives of Civil Engineering, 2018 The problem of effective gas extraction from Polish shale rocks is an interesting research subject for scientists. A properly selected proppant, which protects cracks from closing during the fracturing process, inestimably contributes to an increase of ...
