The mesoscopic constitutive behavior of face-centered cubic metals as a function of the system characteristic dimension recently has been investigated experimentally. Strong size effects have been identified in both polycrystalline submicron thin films and single crystal micro pillars. The size effect is manifested as an increase in strength and hardening rate as the system dimensions are decre...

This paper provides a close look at how to improve the CORBA Trading Service by taking a clustering approach to store and retrieve distributed objects, and to expedite the CORBA service exchange process. We compare several trader models and show how improvements can be made through the use of the object clusters and the indexes built upon these clusters. The underlying trading operations are al...

BACKGROUND To perform closed manual reduction of acute anterior shoulder dislocation using the traction-countertraction technique requires sedation (TCTS) and the participation of 2 people. We studied the modified Milch (MM) technique, a positional reductive maneuver that requires 1 operator, without patient sedation or analgesia. MATERIALS AND METHODS The study comprised 56 prospective nonra...

hip dislocation occurs when the femur does not break and the force is transmitted towards the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. we present the case of a 26 year old patient involved in motor vehicle accident. clinical and imaging (radiography, ct) examination revealed an intertrochanteric fracture associated with ipsi...

BACKGROUND Basilar invagination (BI) combined with atlantoaxial dislocation (AAD) leads to foramen magnum stenosis and medullary spinal cord compression, causing nerve dysfunction. The purpose of the surgery is to remove the bony compression at brainstem ventral side and fix the unstable spinal segment and make it fused stably. Occipital cervical internal fixation system that simultaneously red...

PURPOSE To describe a novel, small-incision, no-fold Descemet stripping automated endothelial keratoplasty (DSAEK) graft injector and to compare complications, visual acuity, and endothelial cell loss with a forceps technique. METHODS An Institutional Review Board-approved, interventional, nonrandomized, consecutive case series analysis of 175 eyes undergoing DSAEK for Fuchs dystrophy and bul...

A point defect based model is developed in two dimensions for the evolution of a group of dislocation loops induced by high dose ion implantation in silicon. Assuming an asymmetric triangular density distribution of periodically oriented circular dislocation loops provides an efficient model reflecting the nonuniform morphology of the loops as observed in transmission electron microscopy (TEM) ...

INTRODUCTION Anterior cruciate ligament ruptures are frequent, especially in sports. Surgical reconstruction with autologous grafts is widely employed in the international literature. Controversies remain with respect to technique variations as continuous research for improvement takes place. One of these variations is the anatomical double bundle technique, which is performed instead of the co...

When the Oxford unicompartmental meniscal bearing arthroplasty is used in the lateral compartment of the knee, 10% of the bearings dislocate. A radiological review was carried out to establish if dislocation was related to surgical technique. The postoperative radiographs of 46 lateral unicompartmental arthroplasties were analysed. Five variables which related to the position and alignment of t...
