2. 21. Road disasters? Modeling and assessment of Swedish roads within crucial climate conditions

   Author : Alireza Nickman; Bo Olofsson; Per-Erik Jansson; Nils-Otto Kitterød; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; Flood; Moisture; Temperature; Groundwater; GIS; Uncertainity; Sweden; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : An efficient maintenance of roads to ensure high accessibility and durability of the transport capacity requires an understanding of how the hydrological response depends on both the road and the landscape characteristics. New methods and data were used to identify and explain interaction between roads and surrounding environment and their influence on hydrologic responses both in watershed scale and road-section scale.

4. 22. NOx Abatement Technique for Marine Diesel Engines - Improved Marine SCR Systems

   Author : Mathias Magnusson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water; ECA compliance.; IMO Tier III; Marine applications; Human element; NOx reduction; Sulfur dioxide; urea-SCR; Human-Machine system;

   Abstract : Growing awareness of the environmental implications of nitrogen oxide (NOX) emissions, such as eutrophication and acidification on land and at sea, has contributed to the development of more stringent international NOX legislations within the framework of the International Maritime Organization (IMO). The most stringent IMO legislation, i.e. READ MORE

5. 23. NOx Abatement Technique for Marine Applications - Improved SCR Systems

   Author : Mathias Magnusson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sulfur dioxide; Human-Machine system; NOx reduction; Water; urea-SCR catalyst; Marine applications; Human element.;

   Abstract : Growing awareness of the environmental implications of emissions of nitrogen oxides (NOX), such as eutrophication and acidification on land and at sea, has contributed to the development of more stringent international NOx legislations within the framework of IMO, with the most stringent legislation, Tier III, representing a NOx reduction of approximately 80% compared with today’s engines. Several NOx abatement technologies are available on the market, the most effective of which may be Selective Catalytic Reduction (SCR). READ MORE

6. 24. Risk Assessment and Decision Support for Managing Drinking Water Systems

   Author : Andreas Lindhe; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drinking water; risk assessment; decision analysis; water safety plan; water supply; multi-criteria decision analysis; dynamic fault tree analysis;

   Abstract : The vital importance of a reliable and safe drinking water supply makes efficient risk management necessary for water utilities. Risks must be assessed and possible risk-reduction measures evaluated to provide relevant decision support. READ MORE

7. 25. Microbial Risks in Surface Water Sources

   Author : Johan Åström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Surface water; Bifidobacteria; Microbial source tracking; Cryptosporidium.; QMRA; Flow-weighted sampling; Pathogens; Bacteroidales; Stochastic modelling; qPCR;

   Abstract : Microbial risks need to be properly handled for the provision of healthy drinking water. The mitigation of pathogens in the water source lowers the risk for infection associated with nominal and suboptimal drinking water treatment. READ MORE
