We therefore excluded surgical cases conducted in the setting of fracture, pelvic or thigh infection, or removal of prior prosthesis, internal fixation device, implant or graft consistent with earlier work [ 14, 15] conducted by members of our team.
The rock mass is crossed by two sets of fractures which are considered to be planar, parallel and persistent.
The shear zone consists of a set of fractures filled with a fine-grained porous fault gouge.
To verify the new model, examples involving deformable porous media containing a single and two sets of fractures were designed, showing good accuracy.
Two algorithms, which employ the level-wise and divide-and-conquer strategies respectively, are designed to mine the set of FRACTUREs.
Different sets of fractures are used to represent grain-boundary pores as well as micro fractures that transect different mineral grains.
The relationship between well yield and distance to fracture lineaments in the three sets of fractures indicates that both of the shear fractures are hydrotectonically more significant than the tensile fractures.
There are four sets of fractures: nearly E W trending fractures, nearly N S trending fractures, NW SE trending fractures, and NE SW trending fractures; the nearly E W trending fractures are the most widely developed.
Under the tectonic compression of Yanshan period and Himalayan period, four sets of fractures are well developed, i.e., N S, NE SW, E W, and NW SE oriented fractures (Zeng and Li 2010).
The eruption was accompanied by morphological changes including opening of two new major sets of fractures (several hundred meters long, several decameters wide) in the dome, and the widening and deepening of historically old craters and fractures.
