Critical stresses necessary to generate dislocation glide loops in Czochralski silicon containing oxide precipitates have been investigated. Using three-point bending and etching techniques, it was possible to determine the minimum shear stress required to generate dislocation glide loops from controlled distribution of precipitates under constant-stress conditions. The generation of glide disl...

OBJECTIVE To determine whether training on shoulder and elbow surgery influences the orthopedist surgeons' preferred technique to address acute acromioclavicular joint dislocation (ACD). METHODS A survey was conducted with shoulder and elbow specialists and general orthopedists on their preferred technique to address acute ACD. RESULTS Thirty specialists and forty-five general orthopedists ...

Address for correspondence; Assoc Prof A-M Kelly Department of Emergency Medicine Western Hospital Private Bag, Footscray 3011 Email: [email protected] Introduction Anterior dislocation of the shoulder is the most common major joint dislocation encountered in emergency departments. Reduction of these dislocations is one of a range of procedures in which emergency physicians need to b...

Peroneal tendon dislocations are most prevalent in the active and athletic population, so accurate diagnosis and management are essential for optimal return of function. Although many nonoperative and surgical management options have been described, the optimal treatment method continues to be debated. In this technique article, a modified retromalleolar groove-deepening technique is described ...

A technique for generating spherically symmetric dislocation solutions of a direct Poincaré gauge theory of gravity based on homogeneous functions which makes Cartan torsion to vanish is presented.Static space supported dislocation and time dependent solutions are supplied.Photons move along geodesics in analogy to geodesics described by electrons around dislocations in solid state physics.Tach...

BACKGROUND This study was conducted to evaluate the functional outcome and MRI findings of arthrocentsis followed by autologous blood injection (ABI) into the joint space for management of chronic recurrent TMJ dislocation. MATERIAL AND METHODS Total ten patients with bilateral chronic recurrent condylar dislocation were included in the study. Arthrocentesis of both TMJ was performed on each ...

Stochastic, discontinuous flow is ubiquitous in the plastic deformation of small-volume metallic materials. We have identified a sizestrengthening effect on the stress to initiate the jerky plastic yielding in nanoscale volumes of copper single crystals, subjected to nanoindentation in different orientations. Such a nanoscale size effect arises due to the stochastic nature of dislocation source...

We present high resolution observations of microstructure and texture evolution during dynamic recrystallization (DRX) of ice polycrystals deformed in the laboratory at high temperature (≈0.98Tm). Ice possesses a significant viscoplastic anisotropy that induces strong strain heterogeneities, which result in an early occurrence of DRX mechanisms. It is therefore a model material to explore these...

purpose: to report occurrence, management, and outcome of late-onset traumatic dislocation of laser in situ keratomileusis (lasik) flaps case report: we report a patient with late-onset lasik corneal flap dislocation after blunt ocular trauma occurring four years after surgery. an ultrasound biomicroscopy (ubm) was performed to view the status of flap and determination of flap thickness. result...

Ossicular injury is a frequent complication of head trauma and temporal bone fractures. An isolated fracture of the malleus with lateral dislocation of the manubrium is extremely rare. High-resolution computed tomography is the method of choice for evaluation of ossicular trauma. Virtual endoscopy (VE) is a novel technique that provides a realistic surface rendering of various organs that can b...
