2. 1. On the making of age : A constructionist study on ageing and later life in the Faroe Islands

   Author : Ása Róin; Catharina Nord; Elisabet Cedersund; Chris Phillipson; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; meaning of ageing; older people; constructionism; Faroe Islands; åldrandets innebörd; konstruktionism; äldre människor; Färöarna;

   Abstract : The aim of this thesis is to explore how older people living in the Faroe Islands make sense of ageing, how political intentions and strategies resonate with the lived reality of ageing and how theories on ageing compare with this reality.This thesis builds on two data sets.

4. 2. Role of phagotrophy in freshwater phytoplankton

   Author : Carina Pålsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aquatic ecology; marine biology; limnology; mixotrophy; phagotrophy; phytoplankton; oligotrophic; clear-water lakes; grazing; competition; nutrient enrichment; autotrophy; heterotrophy; bacterial ingestion; Hydrobiology; Marinbiologi; akvatisk ekologi; limnologi;

   Abstract : Some phytoplankton have the ability to combine phototrophy and heterotrophy within the same individual, which is called mixotrophy. In this thesis, I adress mixotrophy and competitive interactions of mixotrophs and obligate auto- or heterotrophs in relation to the availability of nutrients, light and prey. READ MORE

5. 3. Allochthonous and autochthonous carbon sources of lake bacterioplankton

   Author : Emma Kritzberg; Enhet akvatisk ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marinbiologi; limnologi; akvatisk ekologi; aquatic ecology; marine biology; Hydrobiology; bacterial community composition; bacterial growth efficiency; bacterioplankton; carbon subsidy; dissolved organic carbon; limnology;

   Abstract : Organic substrates for pelagic bacteria are derived from dissolved organic carbon (DOC) in the water column that originates either from primary production from within the lake itself (autochthonous), or import of organic matter from the terrestrial watershed (allochthonous production). This thesis addresses the utilization of allochthonous versus autochthonous carbon (C) sources by lake bacterioplankton. READ MORE

6. 4. Polybrominated dibenzo-p-dioxins and furans : from source of emission to human exposure

   Author : Filip Bjurlid; Jessika Hagberg; Bert van Bavel; Ingrid Ericson Jogsten; Peter Haglund; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PBDD Fs; PCDD Fs; marine mammal; combustion; fire; human milk; occupational exposure;

   Abstract : Brominated flame retardants (BFRs), which are ubiquitous in modern life and the environment, are the major source for polybrominated dibenzo-p-dioxins and furans (PBDD/Fs). The knowledge about PBDD/Fs is lim-ited compared to other environmental pollutants, even though PBDD/Fs show similar toxicity as polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) which are considered to be among the most toxic man-made substances.

7. 5. The Ups and Downs of the Holocene: Exploring Relationships between Global CO2 and Climate Variability in the North Atlantic Region

   Author : Catherine Jessen; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; marklära; geomorfologi; climatology; klimatologi; rapid climate change; Holocene climate; atmospheric CO2 concentrations; geochemical proxy indicators; Paleobotanik; palynology; Geology; palynologi; fylogeni; geomorphology; fysisk geografi; Geologi; physical geography; kartografi; pedology; cartography; phylogeny; Palaeobotany; stomatal frequency; lake sediments;

   Abstract : This thesis aimed to examine the relationship between climate and atmospheric CO2 concentrations through rapid climate changes during the Holocene. Climate was reconstructed using high-resolution, radiocarbon dated, lake sediment geochemical proxies (magnetic susceptibility, loss-on-ignition, total carbon/nitrogen/sulphur determinations and biogenic silica), vegetational reconstruction (pollen analysis) and stomatal frequency based CO2 reconstructions.
