Sediment disasters have negative effects on the operating functions of reservoirs. To decrease the risk of these disasters within reservoir watershed, the establishment of a powerful tool for hazard mitigation / disaster prevention is necessary. Real time data and numerous archives of engineering data, environment information, photo, and video, will not only help people make appropriate decisions, but also bring the biggest concern for people to process and value added. The study collected various types of data about these reservoirs and tried to define some basic data formats / standards, then provide a management platform based on these formats / standards. Meanwhile, to satisfy the practicality and convenience, the disaster management information system is built both provide and receive information, which user can use this disaster management information system on different type of devices. The IT technology progressed very quickly, the most modern system might be out of date anytime, to provide long term service, the system reserved the possibility of user define data format/standard and user define system structure. The system established by this project was based on HTML5 standard language, and use the responsive web design technology. This will make user can easily handle and develop this disaster management information system.","PeriodicalId":424774,"journal":{"name":"Modern Environmental Science and Engineering","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115744764","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}

In this context, climate changes issues are clearly one of the biggest issues for our future. Thus, measures for mitigating its effects are treated, discussed, and analyzed in order to help us to reduce those problems. In this regards, Carbon Capture and Storage (CCS) technology may represent a strategic alternative for CO2 abatement. Using bibliographic review methodology; including law analysis as well as the development of a logical explanation approach and deductive reasoning, in this paper, we analyzed the climate change mitigation strategy of CCS, and the perspectives of implementing this technology in Brazil. Since the CCS activity implies in risks, such as CO2 leakage, we therefore discussed the Civil Liability regarding CCS, focusing on the Brazilian environmental law. Our results show that the lack of a legal and regulatory framework of CCS activities represents the main barrier to its national development.","PeriodicalId":424774,"journal":{"name":"Modern Environmental Science and Engineering","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131984526","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}

If enough creep is experienced, the bolt has the possibility of failure leaving the opportunity for roof instability. In an attempt to quantifying the creep behaviour in polyester resin and cement grout, laboratory-testing procedures were developed. It wasdecided that two separate tests would provide the data needed to fulfil the scope and objectives. The tests chosen were UCS machine deformation testing and Laboratory Short Encapsulation Pull Test (LSEPT). Based on past research in the scope of the project, a methodology was developed along with measuring techniques to accurately monitor the deformation. Based on the data analysis, the displacement for each sample from the pull test suggested that water based resin deforms the most under an induced load whereas grout tends to deform the least. The long term creep test yielded a peak strain of 0.72% and 1.11% for oil and water based resin respectively. Further calculations concluded that oil based resin had the highest resistance to failure with a shear strength of 8.47 MPa, whereas water based resin yielded a shear strength of 4.51 MPa and grout had a shear strength of 5.5 MPa.","PeriodicalId":424774,"journal":{"name":"Modern Environmental Science and Engineering","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116007212","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 concentration of COD, BOD and NH4 in the slaughterhouse wastewater in Vietnam is around 2000 mg/L, 1000 mg/L and 200 mg/L respectively. Gaslift membrane bioreactor (MBR) is a promising technology which is expected to treat wastewater with the same quality and lower operation cost compared to the traditional MBR due to its potential of reducing pumping energy and extension of membrane life. A novel labscale set up of a 500 L aerobic tank plus a 500 L anoxic tank equipped with 2 tubular Ultrafiltration (UF) membrane modules connected with air compressor was constructed to test potential of gaslift MBR to reduce the organic strength and total nitrogen in slaughterhouse wastewater. Different operation parameters such as gas flow rate (Qgas), cross flow velocity (CFV), transmembrane pressure (TMP), Hydraulic Retention Time (HRT), Sludge Retention Time (SRT)... will be tested to search for the optimum operation condition of the system. This study will also prove the potential of energy saving of the gaslift MBR which makes it more feasible to apply for industrial markets and developing countries.","PeriodicalId":424774,"journal":{"name":"Modern Environmental Science and Engineering","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117148789","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}

On the other hand, the annual future precipitation pictured decreasing. However, the seasonal variation of precipitation illustrated significant decrease in summer, under RCP8.5 pathway the decline of precipitation represented 10.68 percent in 2090s. In contrary, future precipitation in winter showed increasing, under high radiative pathway RCP8.5 increase of precipitation projected 3.72 percent in 2090s from the baseline.

In the aftermath of the attacks of Sept. 11, the threat of nuclear terrorism was internationally recognized. As a result, the human resource capacity building technique that ISCN has implemented thus far needs to be analyzed in order to develop more effective training programs. This poster introduces the training techniques and achievements ISCN has made through its nuclear security training courses, including the attempts it has made at the international training course on transportation security, which ISCN co-organized with IAEA in November 2015.
