With the induction of organic contaminants to soil and groundwater it will change the environmental conditions within the plume and hence lead to the variation of indigenous microorganisms. The article aims to investigate the response of indigenous microorganisms to the petroleum contamination. Three polycyclic aromatic hydrocarbons (PAHs) phenanthrene, anthracene and pyrene were selected as the contaminants and tested using laboratory microcosm. The response of indigenous microorganisms to the PAHs induction was analyzed by measuring the change of soil microbial activity, soil catalase activity, contaminants concentration and geochemical parameters. The experimental results showed that: (1) the major parts of the PAHs were absorbed by the soil, its transport was retarded, (2) the soil microbial activity was inhibited at the initial stage of PAHs induction and then slowly increased, (3) the soil catalase activity was stimulated at first with PAHs induction and then inhibited within the range -0.05 mL (0.1 M KMnO 4 )/g (soil).","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76148853","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}

While techniques to measure external pressure are well established, direct measurement of the internal stresses/strains is difficult. A three-dimensional (3D) finite element model of the human leg is developed using the actual geometry of the leg skeleton and soft tissues, which were obtained from 3D reconstruction of CT images. The major tendons are simulated using tension-only truss elements by connecting the corresponding attachment points on the bone surfaces. The bony structures are defined as linearly elastic, while the soft tissue and muscles are assumed to be hyper elastic. The bony and tendons structures are embedded in a volume of soft tissues. To validate this model, the same cadaver is utilized in experiment, during reposition procedure, the force needed to separate the two broken bones and corresponding the distance are recorded. Then, another set of data is acquired from the finite element analysis. After comparison, the finite element model is proved to be acceptable. This simulation model is used in virtual HIT-robot assisted orthopedic surgery system.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"40 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77713390","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}

It was realized that degradation effectives was affected by the density of added microbes. Improving the density of microbes was necessary to reach satisfactory degradation effects on the contaminated river. Therefore a practical recycle cultivation method was studied. It was proved to be practical and effective, for easy to combine with air-lift bioreactor, and the process was easy to implement and take low cost. To achieve high cell density and keep them with high activity, three times cycle was the optimum. It was noticed that recycle cultivation was affected by centrifuge temperature and carbon concentration. More carbon source and higher centrifugal temperature were required to harvest high cell density. But for degradation ability of individual microbe, more carbon was not effective. Finally recycle culture was ended at low centrifugal temperature or higher, because a lot of gels were produced. The gels wrap to the cells so firmly that the cells can't uptake the nutrient and their activities were limited.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"12 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78035315","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}

The sewage sludge had higher pH and organic matter than red soil, thus the application of sewage sludge significantly increased soil pH and decreased monomeric aluminum (Al) concentration in soil solution. In general, there was a trend of increasing plant height, fresh weight, chlorophyll (Chi) content and activities of peroxides (POD) and catalase (CAT), or decreasing contents of malondialdehyde (MDA) and membrane permeability (MP), with sewage sludge ratio increased from 0% to 10%. However, those index mentioned above were opposite at a higher sewage sludge application ratio, ie. 30%, partly due to the high contents of soluble salts and NH 4 -N in sewage sludge. The physiological amelioration (such as keeping higher activities of POD and CAT, more chlorophyll content and lower contents of MDA and MP) for maize grown in Al-toxic soils at 10% sewage sludge ratio provides foundations for the tolerance to Al, thus resulting in highest plant growth.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"89 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80305247","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}
