1. 1. Integrated and Probabilistic Risk Analysis of Drinking Water Systems

   Författare :Andreas Lindhe; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water safety plan; customer minutes lost; probabilistic; fault tree analysis; risk analysis; risk; integrated; drinking water system; hazard; uncertainty;

   Sammanfattning : Drinking water supply is an essential public function but is at the same time exposed to risks. Since a totally risk-free society is not attainable, risks need to be managed efficiently to achieve an acceptable level of risk. LÄS MER

3. 2. Time-resolved Structural and Mechanistic Studies of Water Oxidation in Photosystem II : water here, water there, water everywhere

   Författare :Casper de Lichtenberg; Johannes Messinger; Wolfgang P. Schröder; Holger Dau; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oxygenic Photosynthesis; Photosystem II; TR-MIMS; isotope exchange; EPR; EDNMR; water splitting; water oxidation;

   Sammanfattning : Oxygenic photosynthesis is undisputedly one of the most important chemical processes for human life on earth as it not only fills the atmosphere with the oxygen that we need to breathe, but also sustains the accumulation of biomass, which is not only used as nourishment but is also present in almost every aspect of our lives as building material, textiles in clothes and furniture, or even as living decorations to name a few.The photosynthetic water-splitting mechanism is catalyzed by a water:plastoquinone oxido-reductase by the name of photosystem II (PSII), which is embedded in the thylakoid membranes of plants, algae and cyanobacteria.

4. 3. Decision Support Model for a Sustainable Regional Water Supply

   Författare :Karin Sjöstrand; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multi-criteria decision analysis; inter-municipal cooperation; drinking water supply; cost-benefit analysis; decision support; regionalization; sustainability; economic valuation;

   Sammanfattning : Water supply provision has traditionally been a municipal responsibility. However, environmental, social and economic drivers are now making it more attractive to manage the water services in a more aggregated way. LÄS MER

5. 4. Decision support for sustainable water security

   Författare :Karin Sjöstrand; Dale Whittington; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; risk assessment; decision support; water security; water availability; multi-criteria decision analysis; water scarcity; sustainability; drinking water supply; cost-benefit analysis; marginal abatement cost curves;

   Sammanfattning : Society’s large dependence on water, in combination with climate, socio-economic and demographic changes, places a massive pressure on our freshwater resources. As a result, water crisis, defined as a significant decline in the available quality and quantity of freshwater, is now considered to be among the most critical global risks to society. LÄS MER

7. 5. Multi-Scale Surface Water-Groundwater Interaction : Implications for GroundwaterDischarge Patterns

   Författare :Babak Brian Mojarrad; Anders Wörman; Joakim Riml; Jan Fleckenstein; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; groundwater flow; hyporheic zone; multi-scale modeling; spectral analysis; fragmentation of discharge zones; characteristic parameters; Hydraulik och teknisk hydrologi; Hydraulic and Hydrologic Engineering;

   Sammanfattning : Rivers and aquifers are continuously exchanging water, driven by processes that occur on various temporal and spatial scales, ranging from small streambed features to large geological structures. The interaction between these two components occurs in permeable sediments below the stream channel, called the hyporheic zone. LÄS MER
