In experiment condition, several chemical analytical reagents were used to synthesize the lead analog of ettringite {Pb6[Al(OH)6]2ldr3SO4ldr26H2O}, Ca-Pb ettringite {(Ca,Pb)6 [Al(OH)6]2ldr3SO4ldr26H2O} and plumbite ettringite {3CaOldr Al2O3ldr3CaPbO2ldr31H2O}. The results showed that the lead analog of ettringite and the plumibte ettringite couldn't be synthesized, while Ca-Pb ettringite could be made. This indicated that Pb(II) couldn't be chemically entrapped by ettringite when divalent calcium or sulfate was absent in liquid phase. However, Pb(II) could entrapped into ettringite lattice when calcium ions existed in liquid phase to formed Ca-Pb ettringite. The X-ray diffraction patterns of Ca-Pb ettringite were significantly different from that of Ca-ettringite, indicating that ettringite' lattice been varied after accommodating divalent lead. Experiments on Pb(II) solidified by 100% type I clinker showed that the XRD patterns of the paste at 7-day storage period changed after they doped divalent lead, These further confirmed that Pb(II) could be entrapped into cement minerals including ettringite.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"191 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73613071","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 samples of ash came from circulating fluidized bed calcium-based sintering flue gas desulphurization system of 60 m 2 sintering machine. Based on the component of raw ash and modified ash (changed its component under fixed temperature), batches containing SFGDA ash , granulated blast-furnace slag (GBFS), steel slag, clinker and other admixture for cementing materials were prepared. Specimens were molded using hydraulic press, and their soundness, hydration properties, mechanical properties were determined, micrographs, durability including Acidoresistance, Sulfate resisting , Freeze-thaw resistance and dry shrinkage were studied in accordance with different conserving periods. The results indicate that the batches containing modified SFGD ash up to 20%, steel slag steel 11% to 44%, GBFS 12% to 44%, reducing water agent 0.5%, clinker 23% and CFII 1.5% by mass, meet the cement standard with steel slag and GBFS (GB13592-92, in China). The SFGD ash after modified, when mixed GBFS), steel slag, clinker and other admixture, has necessary requirement to be used as a raw material for production of cement. And the additive of shrinkage reducing agent or expansion admixture should be selected to put into the materials to improve the property in the future.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"19 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2009-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85783500","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}

Cyclosporin A (CSA), a special inhibitor of MPT, were pre-incubated with cells before ultrasound treatment, as well as fructose and pyruvate, respectively. Cell viability was measured by trypan blue dye exclusion test. The apoptosis was assessed by phosphatidylserine externalization and DNA fragmentation. The pattern of the decrease in mitochondrial trans-membrane potential (DeltaPsi m ) was determined by flow cytometry. The optimal apoptosis with minimal lysis was attained with ultrasound at 5.0 W/cm 2 for 1 min. In addition, apoptotic cells increased with increasing incubation time post-treatment and peaked at about 12 h. CSA maintained DeltaPsi m and reduced ultrasound-induced apoptosis, indicating MPT as the molecular mechanism required for apoptosis induced by ultrasound. Moreover, fructose supplementation also maintained DeltaPsi m and reduced ultrasound-induced apoptosis, while pyruvate didn't. It revealed glycolytic products of glycolysis, rather than those produced in tricarboxylic acid (TCA) cycle, were responsible for the reduction of apoptosis.","PeriodicalId":6430,"journal":{"name":"2009 3rd International Conference on Bioinformatics and Biomedical Engineering","volume":"147 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":"86027803","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}
