Dislocation and fracture-dislocation of the hip [PDF]

open access: yesThe Journal of Bone and Joint Surgery. British volume, 1991
Of 54 patients with posterior dislocations of the hip of type I and type II (Stewart and Milford 1954), 47 were followed for a mean period of 6.7 years (2 to 11). Of these, 23 had dislocation with minimal lesions of the acetabulum (type I) and 24 had an avulsed dorsocranial fragment (type II). All were reduced by closed methods within six hours.

Dislocations in graphene [PDF]

open access: yesNew Journal of Physics, 2008
We study the stability and evolution of various elastic defects in a flat graphene sheet and the electronic properties of the most stable configurations. Two types of dislocations are found to be stable: "glide" dislocations consisting of heptagon-pentagon pairs, and "shuffle" dislocations, an octagon with a dangling bond.

The Character of Dislocations in LiCoO2 [PDF]

open access: yes, 2002
Dislocations in LiCoO2 were observed by transmission electron microscopy, and their Burgers vectors were determined by analysis of diffraction contrast in tilting experiments.

Statistical dynamics of dislocation systems: The influence of dislocation-dislocation correlations [PDF]

open access: yesPhysical Review B, 2001
During plastic deformation of crystalline materials, the collective dynamics of interacting dislocations gives rise to various patterning phenomena. A crucial and still open question is whether the long range dislocation-dislocation interactions which do not have an intrinsic range can lead to spatial patterns which may exhibit well-defined ...

DISLOCATION AND FRACTURE-DISLOCATION OF THE PELVIS [PDF]

open access: yesThe Journal of Bone and Joint Surgery. British volume, 1948
1. Fifty dislocations and fracture-dislocations of the pelvis have been reviewed. 2. Complications were unusual. Two patients with rupture of the bladder died; two with rupture of the urethra survived. Of eight patients with retroperitoneal haemorrhage four died; the treatment advised is controlled blood transfusion maintaining a blood-pressure of ...

BROADENING OF RESONANCE LINES BY CHARGED DISLOCATIONS [PDF]

open access: yes, 2002
It is shown that the random electric fields of charge dislocations in insulators should cause appreciable broadening of sharp resonance lines such as spin-resonance signals.

Posterior Dislocation and Fracture—Dislocation of the Shoulder [PDF]

open access: yesActa Orthopaedica Scandinavica, 1980
Two cases of posterior dislocation (PD) and four cases of posterior fracture-dislocation (PFD) of the shoulder are reported. There was one bilateral PD and two bilateral PFD. One PD was treated with closed reduction but in three cases of PFD operative reduction was necessary.

DISLOCATION OF THE KNEE AND DISLOCATION OF THE FOOT [PDF]

open access: yesJournal of the American Medical Association, 1909
A case of anterior dislocation of the knee and a case of backward subastragaloid dislocation of the foot with fracture of the astragalus were both seen at the Baltimore City Hospital in the service of Dr. A. C. Harrison, and are reported because of the rarity of the conditions. Dislocations of the knee compose less than 2 per cent. of all dislocations.

High-resolution electron microscopy of dislocation ribbons in a CMSX-4 superalloy single crystal [PDF]

open access: yes, 2012
High-resolution scanning transmission electron microscopy (STEM) has been used to study the structure of dislocations in single crystal superalloy samples that have been subjected to conditions that favour the primary creep regime. The study has revealed
