The results show that: (1) Under three kinds of loads, the effects of bony structure simplification methods on the maximum equivalent stress of the cartilage in series of flexion angles were significant. At 0¡ãand 80¡ã, the maximum equivalent stresses of bone tissue distinguished models were much bigger than single material models. (2) The bearing load on cruciate ligaments of bone tissue distinguished models reduced. At 0°~60°, the maximum equivalent stress on ACL decreased with the more detailed bony structure. (3) The maximum equivalent stress of bone tissue distinguished models were chiefly bigger than single material models in series of flexion angles. The menisci of bone tissue distinguished models will bear more loads than single material models. (4) The stresses on soft tissue of two kinds of models all elevated with the increase of flexion angle, so bony structure simplification methods did not affect the stress trends with the change of flexion angle. But at 0° and 80°, the effects of bony structure simplification methods on biomechanics of knee's cartilage, ligaments and menisci were significant. The study provided techniques and data for definition of tibiofemoral joint material properties during the mechanical analysis of knee motion.","PeriodicalId":393655,"journal":{"name":"International Conference on Digital Manufacturing and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130036015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silver contained in the electrodes of PDP can be firstly extracted into a solution using nitric acid (HNO3) and ultrasound sonication. An optimum HNO3 concentration is determined to satisfy both the extraction efficiency and the working condition of the chrome-nickel steel container. Later in the process, NaCl is added into the purified extraction solution to obtain sediment mainly comprises of AgCl. Then the sediment is further purified and reduced into metallic silver using different sediment/Fe weight ratios at different temperatures. An optimal sediment/Fe weight ratio is determined, while the temperature is found to be irrelevant with the reduction efficiency. By implementing a series of simple but effective purification methods, silver with a high purity of 99.43 wt% can be obtained. This method has been successfully applied in a silver recovery factory in Mianyang city, China for nearly two years, and has proved to be economically viable and environmentally beneficial.","PeriodicalId":393655,"journal":{"name":"International Conference on Digital Manufacturing and Automation","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116464079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
