Metal-Induced Lung Disease: Lessons from Japan’s Experience: Yukinori KUSAKA, et al. Department of Environmental Health, School of Medicine, Fukui Medical University—Metals inducing occupational respiratory diseases, e.g. metal fever, acute and chronic pneumonia, asthma, bronchitis, chronic obstructive lung disease, pulmonary fibrosis and lung cancer are described. The metals mentioned are the ...

The aim of this study is to compare the metallic and natural fiber reinforced polymer composite bone plates used in humerus fractures. A 3D finite element model was developed to analyze the performance of both types of plates. This study proposed on fabrication of natural fiber powdered material (like Sisal (Agave sisalana), Banana (Musa sapientum) and Roselle (Hibiscus sabdariffa)) Reinforced ...
Thanks to the Kroll process, metallic zirconium can be produced by means of a fairly complicated reduction process. In actual fact, the ore is found as a by-product when mining titanium and tin ore. Since 2003, the price of zirconium has more than doubled. This is the result of increasing demand and also the fact that a considerable amount of energy is needed to release zirconium from its chemi...
The classical wear mechanisms abrasion, fatigue, and adhesion are the most frequent causes of surface changes of ultra high molecular weight polyethylene (UHMWPE) in artificial joints. The counterpart material has a strong influence on the wear and friction behavior of artificial joints due to its abrasive properties and adhesive interaction with UHMWPE. The formation of a transfer layer on the...
New low modulus β-type titanium alloys for biomedical applications are still currently being developed. Strong and enduring β-type titanium alloy with a low Young's modulus are being investigated. A low modulus has been proved to be effective in inhibiting bone atrophy, leading to good bone remodeling in a bone fracture model in the rabbit tibia. Very recently β-type titanium alloys with a self...
Zirconium carbide nanoparticles were produced by wire explosion process by exploding zirconium conductor in methane ambiance. X-ray diffraction studies of the particles produced by wire explosion process confirm the formation of cubic zirconium carbide particles. The results of the study indicates that unreacted zirconium content in the zirconium carbide powder could be reduced by exploding the...
