A two-temperature thermal non-equilibrium model is developed and applied to the threedimensional and time-dependent simulation of the flow inside a DC arc plasma torch. A detailed comparison of the results of the non-equilibrium model with those of an equilibrium model is presented. The fluid and electromagnetic equations in both models are approximated numerically in a fully-coupled approach b...

The need to improve plasma spraying processes has motivated the development of computational models capable of describing the arc dynamics inside plasma torches. Although progress has been made in the development of such models, the realistic simulation of the arc reattachment process, a central part of the arc dynamics inside plasma torches, is still an unsolved problem. This study presents a ...

PURPOSE To report the one-year outcome of 44 patients treated with a novel technique of calcaneoplasty and reattachment of the Achilles tendon. METHODS 15 men and 29 women (mean age, 53 years) with insertional tendinopathy of the Achilles tendon underwent calcaneoplasty, retrocalcaneal bursa excision, debridement and reattachment of the Achilles tendon with suture anchors via a lateral approa...

PURPOSE To report the clinical features and surgical outcomes of retinal detachment in mentally retarded patients. METHODS Retrospective review of records of mentally retarded patients who had retinal reattachment surgery at the authors' institutions between February 1994 and February 2000. There were 8 patients with 13 surgically treated eyes. Demographic and clinical data were abstracted fr...

Fifty-nine cases of trochanteric wire revision following hip arthroplasty with trochanteric osteotomy and reattachment were identified and their outcome was studied. Two were infected and were excluded. Five were revised for instability: four became stable while one continued to have persistent dislocation. Fifty-two were revised for pain, 36 by removal of the trochanteric wire and 16 by reatta...
