We investigated the properties of poplar thermo-chemical mechanical pulp (CTMP) and effluent properties after pretreatment with crude enzymes secreted from several white-rot fungi (Trametes sp. lg-9, Coriolus versicolor sdu-4 and Phanerochaete chrysosporium 25). Pretreatment with all these crude enzymes improved CTMP proterpties, and Trametes sp. lg-9 crude enzymes specifically improved CTMP beating properties, reduced energy input for the beating process. The pretreatment also facilitated bleaching of the CTMP and the charge of bleaching chemicals could be greatly reduced. On the other hand, C. versicolor sdu-4 crude enzymes pretreatment increased the pulp brightness when carried out before CTMP bleaching, while enzyme pretreatment after CTMP bleaching improved other physical indices of pulp. Pretreatment with crude enzymes from P. chrysosporium 25 improved pulp physical properties at a less extent, and pretreatment before bleaching decreased the CTMP brightness. Our findings demonstrated the feasibility of green manufacturing of CTMP and provided additional experimental evidence of using crude enzyme preparation from fungi to improve pulp properties and decrease effluent discharge. Therefore, they will contribute to the advance of green manufacturing pulping in the pulp and paper industry.","PeriodicalId":6340,"journal":{"name":"2011 International Conference on Electric Technology and Civil Engineering (ICETCE)","volume":"15 1","pages":"4178-4181"},"PeriodicalIF":0.0,"publicationDate":"2011-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87492733","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}

So three mathematical models were created through different high-span ratios, that were 3∶10,3∶5,3∶3, and stress failure curve of elasticity solution was compared with stress failure curve of material mechanics solutions and to validated the correctness of the corrected formula. critical failure equation of backfill roof was derived based on maximum stress criterion, the critical failure curve of backfill was achieved by substituting the mechanics parameters of different stresses into the analytical formulas, and failure modes of backfill roof is found through physical modeling experiment. The results show that the failure of backfill roof is first happening from the center at the bottom of backfill, the final result is that falling arch. Finally, effective measures were proposed to avoid failure of backfill roof.","PeriodicalId":6340,"journal":{"name":"2011 International Conference on Electric Technology and Civil Engineering (ICETCE)","volume":"86 9 1","pages":"2770-2774"},"PeriodicalIF":0.0,"publicationDate":"2011-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87685304","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 landslide occurred during the first evaluation in the ratio of 1∶1.25, and then twice during the following reinforcement in the ratio of 1∶3. As a result, the scale of the landslide enlarged 20 times and the slope was still in low deformation. Based on the engineering geological conditions, the landslide character and the monitoring data, the evaluation model of slope's process stability was built by use of FEM, which simulated the course of the landslides. And then, the landslide mechanism was analyzed and key points of the following construction process control were put forward. The result shows Process stability of high cutting slope under complex geological conditions during the construction is a controllable procedure variable, lacking effective control is the main reason for the landslide. The method, consist of FEM simulation and monitoring is effective in researching slope's process stability during construction and the mechanism of landslide, meanwhile it also provided dynamic guidance for the excavation and reinforcement.","PeriodicalId":6340,"journal":{"name":"2011 International Conference on Electric Technology and Civil Engineering (ICETCE)","volume":"17 1","pages":"5276-5279"},"PeriodicalIF":0.0,"publicationDate":"2011-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86860420","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}
