Steel plates are used in various structures, such as the structures of the deck and body of ships, bridges, and aerospace industry. In this study, we investigate the buckling and post-buckling behavior of rectangular steel plates having circular cutouts with two boundary conditions: first, clamped supports at upper and lower ends and free supports at other edges; second, clamped supports at upp...

Abstract Knee arthroplasty follow-up involves only a limited number of X-ray-based implant condition assessments at extended intervals. Polyethylene (PE) wear knee endoprosthesis often progresses unnoticed until symptomatic adverse effects become apparent or failure occurs. A PE measuring concept, consisting an implanted passive sensor and extracorporeal readout unit, was previously presented b...

The design of interior cutouts in laminated composite panels is of great importance in aerospace, automobile and structural engineering. Based on the Tsai–Hill failure criterion of the first ply, this paper presents a newly developed Fixed (FG) Grid Evolutionary Structural Optimization (ESO) method to explore shape optimization of multiple cutouts in composite structures. Different design cases...

Acromioclavicular joint (ACJ) dissociation is one of the common injuries affecting adults. The stability of ACJ largely depends on the integrity of acromioclavicular ligament, coracoclavicular ligament, capsule, trapezius muscle and deltoid muscle. The injury has been classified by Rockwood into six types and treatment options can be guided by the classification. TightRope fixation is one of th...

Our previous studies showed, bacterium Aquamicrobium sp. SK-2 can degrade biphenyl and polychlorinated biphenyls (PCBs). In the present study, proteins involved in degradation was evaluated using various molecular biology methods. The gene bphC strain identified polymerase chain reaction method. Further key enzyme degradation, 2,3-dihydroxybiphenyl 1,2-dioxygenase (BphC) purified through anion ...

Abstract To deeply analyze the performance of paper-cutting elements in interior space design, this paper explores artistic expression elements. The BIM model is constructed based on TVL algorithm, and a noise-reducing style migration method with an additional total variable loss function used to fuse texture features specific so that generated target object area more intensively. algorithm sup...
