This paper discusses the use of Linear Mixed Models (LMM) and Generalized Linear Mixed Models (GLMM) to predict the wear and damage trajectories of railway wheelsets for a fleet of modern multiple unit trains. The wear trajectory is described by the evolution of the wheel flange thickness, the flange height and the tread diameter; whereas the damage trajectory is assessed through the probabilit...

mandibular discontinuity defects following a segmental mandibulectomy defects present a major challenge to the rehabilitation team. with no immediate intervention to rehabilitate the patient, definitive mandibular guidance prostheses with a metal guiding flange and acrylic teeth on the resected side can be used successfully to stabilize the occlusion and correct the deviation. the present case ...

conclusions bilateral anterior shoulder dislocation is rare. it could be undiagnosed, especially when there is no clear history of major trauma. by awareness of such unusual possibility, early diagnosis, treatment, and reduction can provide desirable outcome. introduction shoulder dislocation is the most common presentation of joint dislocation in emergency department (ed). bilateral shoulder d...

Comprehensive upgrades of gas turbine involve the replacement of “flange-to-flange” parts with more advanced designs. Because late-model gas turbines already incorporate advanced technology, these comprehensive upgrades apply only to older gas turbines that are part of a series or model line that the original equipment manufacturer (OEM) has redesigned. Examples of these model lines include the...

With the aim of introducing laser-arc hybrid welding (LAHW) into field large steel shipbuilding, a study was carried out to construct T-shaped fully penetrating welded joint with weld length 3,000 mm in one pass. Tack for installation members, which is preliminary step LAHW, by CO2 gas shielded arc welding. Since effect main LAHW on tack has not been sufficiently confirmed, investigations were ...

In this report, we present the case of a 64-year-old woman who sustained a Burch-Schneider cage fracture. Prior to this event, she underwent repeated acetabular reconstructions, but in the end prosthesis removal was performed as a salvage procedure. We believe that the primary cause of the fracture was metal fatigue facilitated by intraoperative re-contouring of the flange, as well as reuse of ...
