The gauge theory of dislocations: a uniformly moving screw dislocation [PDF]

Proc. R. Soc. A (2009) 465, 2505-2520, 2009
In this paper we present the equations of motion of a moving screw dislocation in the framework of the translation gauge theory of dislocations. In the gauge field theoretical formulation, a dislocation is a massive gauge field. We calculate the gauge field theoretical solutions of a uniformly moving screw dislocation.

A comparison of ketamine versus etomidate for procedural sedation for the reduction of large joint dislocations

International Journal of Critical Illness and Injury Science, 2016
Study Objectives: Ketamine and etomidate are used for procedural sedation (PS) to facilitate the performance of painful procedures. We hypothesized that ketamine produces adequate and comparable sedation conditions for dislocated large joint reduction ...

Management and radiographic outcomes of femoral head fractures. [PDF]

, 2017
BackgroundFemoral head fractures are uncommon injuries. Small series constitute the majority of the available literature. Surgical approach and fracture management is variable. The purpose of this study was to evaluate the incidence, method of treatment,

The gauge theory of dislocations: a nonuniformly moving screw dislocation [PDF]

Physics Letters A 374 (2010), 3092--3098, 2010
We investigate the nonuniform motion of a straight screw dislocation in infinite media in the framework of the translational gauge theory of dislocations. The equations of motion are derived for an arbitrary moving screw dislocation. The fields of the elastic velocity, elastic distortion, dislocation density and dislocation current surrounding the ...

Traumatic costovertebral joint dislocation [PDF]

BMJ Case Reports, 2020
Rib fractures due to blunt trauma are a common chest injury seen at the emergency department; however, injuries to the costovertebral joints are very rare. We present a case of a 24-year-old man who was admitted after a high-speed car collision and was assessed in a level 1 trauma centre in Amsterdam.

Isolated talus dislocation: a case report

Journal of the Foot & Ankle, 2022
Peritalar dislocation is a rare injury, usually associated with fractures. It mainly affects males in high-energy traumas such as falls from height, car accidents, or even torsional traumas during the practice of sports activities.

Metatarsal Shaft Fracture with Associated Metatarsophalangeal Joint Dislocation

Case Reports in Orthopedics, 2016
Metatarsophalangeal joint dislocations of lesser toes are often seen in the setting of severe claw toes. Traumatic irreducible dislocations have been reported in rare cases following both low-energy and high-energy injuries to the forefoot.

Oscillatory deviations from Matthiessen's rule due to interacting dislocations [PDF]

J. Phys.: Condens. Matter 29, 325702 (2017), 2016
We theoretically examine the validity of Matthiessen's rule caused by strong dislocation-dislocation interaction using a fully quantized dislocation field, where its degree of deviation is quantified at arbitrary electron energy, dislocation-electron and dislocation-dislocation distances and interaction strengths.

The nature of deformation-induced dislocations in SrTiO3: Insights from atomistic simulations [PDF]

, 2022
The nature of mechanically induced dislocations in SrTiO3 at low temperatures has been a disputed matter for a long time. Here we provide a systematic overview of the existing knowledge on dislocations in stoichiometric SrTiO3 complemented by computational models of several of the proposed dislocation types.
