Based on a Wharf project in Chongqing, this paper carries out experimental research and nonlinear finite element analysis the impact resistance of steel casing rock socketed pile inland river frame under horizontal load. The results show that force its growth rate, bending moment concrete core, maximum lateral displacement top increase significantly with energy, linear is better. Under same mas...

The pulsation of the bubbles resulting from underwater explosions can lead to severe damage structure ship’s hull, and even its sinking. To study mechanism a simplified hull girder (SHG) subjected near-field explosion bubble, Coupled Eulerian–Lagrangian (CEL) method based on verifications calculation accuracy was used simulate 11 SHG structures. sagging bend SHGs analyzed perspective plastic hi...

The rotating hinge knee prosthesis is a popular intervention in patients lacking stability with highly constrained total knee arthroplasty. Despite improvements in design, nonmechanical and mechanical complications continue to be a problem. Dislocation of the hinge has been widely described, mainly due to the component fracture. Few reports describe isolated dislocation of the rotating stem. We...

an energy based damage index based on a new nonlinear finite element (fe) approach applicable to rc structures subjected to cyclic, earthquake or monotonic loading is proposed. the proposed method is based on the evaluation of nonlinear local degradation of materials and taking into account of the pseudo-plastic hinge produced in the critical sections of the structure. a computer program is dev...

BACKGROUND A large proportion of the plastic surgery literature is dedicated to the breast. It is one of the most common topics in our specialty, yet it is unclear which articles have been the most influential. The purpose of this study was to identify the top 100 most-cited articles on breast in the plastic surgery literature and examine the characteristics of each individual article. METHOD...

BACKGROUND Mesangial IgA1 deposition is characteristic of IgA nephropathy (IgAN). Structural abnormalities of the IgA1 glycoprotein may play a key role in its mesangial deposition, particularly the recently described abnormalities of O-glycosylation of the IgA1 hinge region. The mechanism of abnormal O-glycosylation has not yet been elucidated; it is not clear whether there is an alteration in ...

The two domains of flavocytochrome b2 are connected by a typical hinge peptide. To probe the role of the hinge in modulating the efficiency of intraprotein electron transfer between these two domains, a number of mutant enzymes with truncated hinge regions were previously constructed and characterized [Sharp, Chapman and Reid (1996) Biochemistry 35, 891-899]. In the present study two mutant enz...

We have investigated whether improvements in design have altered the outcome for patients undergoing endoprosthetic replacement of the proximal tibia following resection of a tumour. Survival of the implant and 'servicing' procedures have been documented using a prospective database. A total of 194 patients underwent a proximal tibial replacement, with 95 having a fixed-hinge design and 99 a ro...

In this paper, flexure hinges as the main part of the actuators frame are studied considering different profiles of flexure hinges and effective design parameters to introduce the best profile of the hinge based on the application that is needed. For this purpose five different profiles (right circular, elliptical, corner-filleted, hyperbolic and parabolic) of flexure hinges have been considere...
