In today’s marketplace the repairs of various components especially long lead items for turbomachinery equipment are an important factor for the maintaining reliability and performance of the equipment. This paper will describe repairs applied to compressors

Fifteen to 20 years ago, transversalis and Shouldice Hospital repairs were standard, with a 4% to 6% rate of recurrence. With a focus on recurrence, various mesh repairs were proposed to reduce the incidence of recurrence. With these repairs, an increased incidence of inguinodynia due to the entrapment of the nerves proximate (adjacent) to the mesh has been observed. Many surgeons doubted its e...

This paper is concerned with the dependence structure of a multi-component, cumulative damage shock model, in which a system of components is subject to correlated shock damages and group repairs. A component fails when its cumulative damage exceeds a given threshold, and is then replaced by a new component. We incorporate a block maintenance schedule that simultaneously performs imperfect repa...

BACKGROUND The success rate of rotator cuff repairs is variable. This study was performed to evaluate the ability of recombinant human bone morphogenetic protein-12 (rhBMP-12), administered in several carriers, to accelerate healing in a sheep model of rotator cuff repair. METHODS Local retention of tracer amounts of radiolabeled rhBMP-12, added to non-radiolabeled rhBMP-12 delivered in buffe...

PURPOSE To compare the outcome of open versus endoscopic gluteal tendon repair. METHODS An extensive review of PubMed was conducted by 2 independent reviewers for articles containing at least 1 of the following search terms: gluteus medius, gluteus medius tear, gluteus medius tendinopathy, gluteus medius repair, hip abductors, hip abductor tears, hip abductor repair, hip rotator cuff, hip rot...

Active integrity constraints (AICs) are a form of integrity constraints for databases that not only identify inconsistencies, but also suggest how these can be overcome. The semantics for AICs defines different types of repairs, but deciding whether an inconsistent database can be repaired is a NPor Σ p-complete problem, depending on the type of repairs one has in mind. In this paper, we introd...
