This case describes a subtotal cricoid cartilage defect reconstructed with a prefabricated composite free flap. A 61-year-old man with a chondrosarcoma of the cricoid cartilage required a subtotal cricoidectomy. The resulting defect was successfully reconstructed with a two-stage prefabricated radial forearm free flap utilizing auricular cartilage. Our case further adds to the evidence that pre...

Purpose As a strand in industrialization movement architecture, engineering and construction (AEC) industry, prefabricated (PC) has gained widespread popularity due to high efficiency, energy saving, low environmental impacts, safety other advantages of PC. Well-managed supply chain can further leverage the However, there is lack more systematically overview (PCSC). This paper aims comb current...

BIM technology simulates visual information data by integrating the of construction projects.Through presentation parameters, it is convenient for better collaborative management process.BIM applied to integrate during prefabricated structures, analyze source projects, and build a digital model.Based on technology, which has characteristics integration function, simulation, cross region coordin...

During the first decade of 21st century, São Paulo's State Government, in Brazil, promoted construction a series schools designed by different local architectural firms, using system prefabricated pieces that allowed adapting projects to sites and demands each region, keeping budget under control. This initiative building dozens buildings, relieving school deficit most impoverished regions stat...

With respect to the dissipation of energy through plastic deformation of joints of prefabricated wall units, the paper points out the principal importance of efficient reinforcement of the prefabricated system at its joints. The method, quality and amount of reinforcement are essential for reaching the necessary degree of joint ductility. The paper presents partial results of experimental resea...

Construction, as an important producer of energy, material, and waste emissions, the high energy consumption problem has not been solved. Prefabricated buildings have become more popular promoted in China recent years. This study takes prefabricated traditional cast-in-situ research objects divides into five stages: factory building materials production, component transportation, field installa...

PURPOSE To compare prefabricated and custom-made bars used for implant-retained mandibular complete overdentures. MATERIALS Ten completely edentulous patients were selected for replacement with dental implants. Each patient received 2 (press-fit) dental implants, 1 implant on each side in the canine regions of the mandible. The implants were left submerged (unloaded) for a healing osseointegr...
