  1. 1. Export and sources of organic carbon in the Lena River basin, Northeastern Siberia

    Author : Liselott Kutscher; Carl-Magnus Mörth; Per Andersson; Don Porcelli; Peter Raymond; Sebastian Sobek; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; organic carbon; DOC; POC; organic matter; NOM; DOM; POM; Lena River; organsikt kol; DOC; POC; organiskt material; NOM; DOM; POM; Lenafloden; geokemi; Geochemistry;

    Abstract : Permafrost areas are considered to be one of the largest terrestrial storages of carbon. In a warming climate these areas are expected to experience changes in carbon transport to rivers and the oceans due to permafrost thawing, which could enhance erosion, change water flow pathways and increase greenhouse gas emissions.

  2. 2. The role of terrestrial and phytoplankton-derived organic matter in planktonic food webs

    Author : Anja Wenzel; Ann-Kristin Bergström; Tobias Vrede; Maarten Boersma; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Daphnia; phytoplankton; heterotrophic bacteria; terrestrial particulate organic material; food quality; food quantity; fatty acids; oligotrophic; Light:Nutrient-Hypothesis; limnologi; Limnology;

    Abstract : Lakes are important global ecosystems and many of them are nutrient-poor (unproductive). Especially in northern boreal latitudes, lakes may be heavily subsidized by terrestrial organic material (t-OM) from peat layers in the catchment. READ MORE

  3. 3. Characterization of PAC-contaminated soil with the focus on availability, leachability and biological activities

    Author : Monika M. Lam; Magnus Engwall; Maria Larsson; Patrik Andersson; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Polycyclic aromatic compounds; Availability; Mobility; Soil; Risk assessment; AhR-mediated activity; ER-mediated activity;

    Abstract : Current risk assessments of polycyclic aromatic compounds (PACs)-contaminated soil are often based on the 16 priority PAHs and do not consider availability of PACs in soil sufficiently. This may lead to uncertainties of the assessment, since important contaminants can be overlooked and only a small fraction of contaminants is available for the uptake for organisms. READ MORE

  4. 4. Acute postoperative and cancer-related pain management, Patients´ experiences and perceptions in relation to health-related quality of life and the multidimensionality of pain

    Author : Barbro Boström; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anestesiologi; intensivvård; intensive care; Anaesthesiology; SF-36.; postoperative pain; Pain-o-Meter; perceptions; pain management; nursing care; Health-Related Quality of Life; American Pain Society; cancer-related pain;

    Abstract : This thesis describes patients in acute postoperative pain as well as patients with acute cancer-related pain in palliative care, and their experiences and perceptions of pain management in relation to HRQOL and the multidimensionality of pain. A combination of qualitative and quantitative methods was chosen. READ MORE

  5. 5. Separation of plastics by flotation

    Author : Huiting Shen; Luleå tekniska universitet; []

    Abstract : This thesis analyses and summarises the importance of plastics waste recycling and plastics waste separation, presents an innovative principle for plastics flotation, and provides various methods for the separation of plastics mixtures. The objective is to understand the mechanisms for selective flotation separation of plastics, get plastics mixtures separated and enable more plastics wastes to be recycled. READ MORE
