  2. 11. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces

    Author : Petra M Hansson; Per M. Claesson; Agne Swerin; Adam C Simonsen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrophobic surface; superhydrophobic surface; atomic force microscopy; surface forces; capillary forces; cavitaion; surface roughness; friction; wetting; confocal Raman; contact angles; surface preparation; Langmuir-Blodgett;

    Abstract : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.

  4. 12. Hydrodynamic modelling of microbial water quality in drinking water sources

    Author : Ekaterina Sokolova; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; faecal contamination; QMRA; faecal indicators; pathogens; risk assessment; microbial source tracking; Bacteroidales; E. coli;

    Abstract : The faecal contamination of water sources can cause waterborne disease outbreaks among drinking water consumers. To design drinking water treatment and minimise consumer health risks, knowledge on source water quality is needed. READ MORE

  5. 13. Environmental management of water systems under uncertainty

    Author : Christian Baresel; Georgia Destouni; Vladimir Cvetkovic; Keith Beven Beven; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water Resources Engineering; Water engineering; Vattenteknik;

    Abstract : Hydrological drainage/river basins constitute highly heterogeneous systems of coupled natural and anthropogenic water and pollutant flows across political, national and international boundaries. These flows need to be appropriately understood, quantified and communicated to stakeholders, in order to appropriately guide environmental water system management. READ MORE

  6. 14. Cooperation and Conflict amid Water Scarcity

    Author : Stefan Döring; Håvard Hegre; Ashok Swain; Päivi Lujala; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; conflict; cooperation; water; water scarcity; drought; communal violence; non-state actors; environmental peacebuilding; environmental security; groundwater; water security; geo-referenced data; climate variability; natural disaster; resilience; Peace and Conflict Research; Freds- och konfliktforskning;

    Abstract : Over two billion people remain without safe drinking water and more than four billion lack basic access to sanitation. Safely managing water is key for livelihoods, food security, energy production, and overall socio-economic development. This dissertation analyzes how scarce water resources affect cooperation and conflict.

  7. 15. Fluoride in surface water and groundwater in southeast Sweden : sources, controls and risk aspects

    Author : Tobias Berger; Mats E. Åström; Pasi Peltola; Henrik Drake; Olle Selinus; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorine; fluoride; water-rock interaction; granite; crystalline bedrock; surface water; groundwater; Götemar; drinking water quality; aluminium; speciation; fluorosis; PBA; Miljövetenskap; Environmental Science;

    Abstract : The aim of this thesis is to determine the sources, controls and risk aspects of fluoride in surface water and groundwater in a region of southeastern Sweden where the fluorine-rich 1.45 Ga circular Götemar granite (5 km in diameter) crops out in the surrounding 1.8 Ga granites and quartz monzodiorites (TIB rocks).
