The National Institute for Occupational Safety and Health (NIOSH) conducted a study of ironworkers to evaluate their risk for developing back and hand injuries from hand-tying reinforcing steel bar and to investigate whether power tying tools can be an effective intervention for the prevention of work-related musculoskeletal disorders. A field investigation of biomechanical loading when using 3...

This paper describes the main improvements we made in two of the basic modules in our HMMbased large vocabulary speaker independent continuous speech recognition system: namely in the acoustic modelling and in the search engine. For the acoustic modelling, we paid special attention both to improved parameter tying at the density and at the state level, and to fast evaluation of the HMMs. For th...

This paper explores tying in the situation where a multi-product firm without monopoly power competes against several single-product firms. It considers two independent markets: one for a horizontally differentiated good, the other for a homogeneous good. As opposed to the widely accepted opinion that tying may be profitable only in the case of monopoly power, it is shown that under reasonable ...

INTRODUCTION: Orthopaedic surgeons have focused on improving the functional and structural outcomes of arthroscopic rotator cuff repair and labral repair through the development of biomechanically superior surgical techniques such as double-row fixation, suture-bridge fixation, and compression double-row fixation. To obtain the maximum benefit from these repair techniques, secure knot tying is ...

HYPOTHESIS New hemostatic methods have been widely used in open and laparoscopic surgery. The LigaSure Precise diathermy system (Valleylab, Boulder, Colo) has been recently used in thyroid surgery. We hypothesized that its use could lead to reduced operative time and fewer complications compared with conventional knot tying in total or near-total thyroidectomy. DESIGN Prospective case-control...

The success of an arthroscopic procedure depends considerably on the successful and secure tying of arthroscopic knots, which reapproximate and stabilize avulsed or torn soft tissues to their original bed. Failure to perform appropriate knot tying may jeopardize the success of the operation. We describe a simple and reliable technique for intraoperative arthroscopic replacement of the suture th...

Background: During the third year general surgery clerkship, medical students are required to develop laparoscopic knot-tying skills. Knot-tying skills studies often rely on objective variables (e.g., time, materials used, number of iterations) that lend themselves to correlational analysis of pre- and post-intervention skill level. This study differs by examining how instructional intervention...
