  2. 1. In situ remediation of contaminated sediments using thin-layer capping : efficiency in contaminant retention and ecological implications

    Author : Göran S. Samuelsson; Jonas S. Gunnarsson; Bart Koelmans; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Contaminated Sediment Remediation; Activated Carbon; Benthic Community; Ecological Effects; Stress; Resilience; Contaminant Sequestration; Capping Efficiency; Bioavailability; Bioaccumulation; Sediment-to-water fluxes; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Hydrophobic organic contaminants (HOCs) often reside in sediments sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.

  4. 2. Drivers of carbon sink function in tropical seagrass beds : influence of carbon import, plant composition, seascape configuration and human activities

    Author : Rashid O. Ismail; Mats Björk; Martin Gullström; Maria E. Asplund; Amelia S. Buriyo; Matern S.P. Mtolera; Teresa Alcoverro; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon sequestration; tropical seagrass meadows; coastal seascape; landscape configuration and transformation; calcification; allochthonous carbon; community respiration; carbon sink; human disturbance; coastal conservation; Plant Physiology; växtfysiologi;

    Abstract : Seagrass meadows are effective carbon sinks, sequestering atmospheric CO2 and capturing allochthonous organic material, storing organic carbon (Corg) in their sediments, so called Blue Carbon. In tropical areas, seagrass meadows have a high number of calcareous organisms, which can offset carbon sequestration by releasing CO2 through their calcification. READ MORE

  5. 3. Speleothems as environmental recorders : A study of Holocene speleothems and their growth environments in Sweden

    Author : Hanna S. Sundqvist; Karin Holmgren; Anders Moberg; Regine Hock; Frank McDermott; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; speleothems; palaeoclimate; stable isotopes; luminescence; karst hydrology; Holocene; Sweden; Jämtland; Physical geography; Naturgeografi;

    Abstract : The main aim of this thesis was to contribute with detailed information of regional environmental change during the Holocene through studies of speleothems and their growth environments from two caves, Korallgrottan and Labyrintgrottan in northwestern Sweden, and a cellar vault in Uppsala. This was done through studies of stable isotopes and luminescence properties in the speleothems in combination with a detailed monitoring study in Korallgrottan. READ MORE

  6. 4. Figuring Worlds; Imagining Paths : A Feminist Exploration of Identities in Higher Education Biology

    Author : Katerina Pia Günter; Annica Gullberg; Ingrid Ahnesjö; Karin S. Lindelöf; Maria Berge; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biology Education; Communities of Practice; Discourse Analysis; Feminist Science Studies; Figured Worlds; Gender; Higher Education; Science Education; Science Identity; Genusvetenskap; Gender Studies; Pedagogik; Education; Biologi; Biology;

    Abstract : Higher education biology is a natural science discipline that is numerically female biased on undergraduate level across most international contexts. In Sweden, Germany, and the UK, for example, more than 60% of all undergraduate students are women. READ MORE

  7. 5. The Macroeconomics of the Term Structure of Interest Rates

    Author : Paolo Zagaglia; Matthew Lindquist; Refet S. Gurkaynak; Stockholms universitet; []

    Abstract : This thesis consists of four papers, summarized as follows. "The Term Structure of Interest Rates and the Monetary Transmission Mechanism" This paper provides empirical evidence that the term structure of interest rates is an integral part of the monetary transmission mechanism.
