1. 1. Hazard screening of contaminated sites : bioavailable fractions and biological in vitro tools

   Författare :Daniel Ragnvaldsson; Mats Tysklind; Per Leffler; Lars Lövgren; Bengt-Erik Bengtsson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hazard screening; bioavailability; metal pollution; in vitro cytotoxicity; water extraction; CCA; arsenic genotoxicity; genotoxicity; Contaminated soil; Environmental chemistry; Miljökemi;

   Sammanfattning : The environmental bioavailability of contaminants, rather than their total concentrations in the soil compartment play a decisive role for the risks associated with contaminated sites. Various soil constituents and abiotic conditions have strong influence on bioavailability, which may vary substantially between different locations. LÄS MER

3. 2. The importance of wetlands for biodiversity in agricultural and urban landscapes

   Författare :Elisabeth Lundkvist; Linköpings universitet; []
   Nyckelord :Dytiscidae; diving beetles; wetland; pond; diversity; assemblage; CCA; ordination; variation partitioning; community structure; flight; migration;

   Sammanfattning : The aim in this thesis was to study the importance of different types of wetlands for the biodiversity in a landscape. The landscapes were both agricultural and urban, and wetlands were in different successional stages. Diving beetles (Dytiscidae) were used as study organisms. LÄS MER

4. 3. Data Mining and Analysis for Characterizing Paper from On-line Multisensor Measurements

   Författare :Marcus Ejnarsson; Adas Gelzinis; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Feature Extraction; Kernel Based Novelty Detection; Kernel CCA; Monitoring; Newsprint; Paper Web; Time-Series Representation; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The objective of this thesis is to develop a multi-resolution tool for screening paper formation variations, aiming to detect abnormalities in various frequency regions ranging from millimeters to several meters. The abnormalities detected in different frequency regions give an indication for the paper maker about specific disturbances in the paper production process. LÄS MER

5. 4. Diffuse emissions from goods : influences on some societal end products

   Författare :Jennie Amneklev; Bo Bergbäck; Hans-Bertil Wittgren; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arsenic; bismuth; CCA-treated wood; copper; material flow analysis; silver; substance flow analysis; urban flows; Miljövetenskap; Environmental Science;

   Sammanfattning : End products of society (e.g. sewage sludge and incineration ashes) can be used as indicators of the use of chemicals in consumer goods. Through upstream work the sources of substances released from goods may be identified before the emissions reach the end products. LÄS MER

7. 5. Disaster risk management and climate change adaptation in urban contexts: Integration and challenges

   Författare :Claudia Rivera; Avdelningen för Riskhantering och Samhällssäkerhet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mainstreaming; Nicaragua; risk governance; Sweden; urban planning; disaster risk reduction; disaster risk management; Climate change adaptation;

   Sammanfattning : An increasing number of disasters continue to affect urban populations and housing infrastructure. The overwhelming majority of them have been caused by climate-related events. This situation has made the creation of synergies between climate change adaptation (CCA) and disaster risk management (DRM) urgent. LÄS MER
