  2. 16. Soil organic carbon in permafrost terrain : Total storage, landscape distribution and environmental controls

    Author : Gustaf Hugelius; Peter Kuhry; Jan Boelhouwers; Stockholms universitet; []
    Keywords : ;

    Abstract : High latitude terrestrial ecosystems are considered key components in the global carbon (C) cycle and hold large reservoirs of soil organic carbon (SOC). To a large degree, this SOC is stored in permafrost soils and peatlands and is vulnerable to remobilization under future global warming and permafrost thawing. READ MORE

  4. 17. The mammalian peroxisome : ‛its function and distribution’

    Author : Veronika Tillander; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Peroxisomes are essential organelles for normal cell functions in all organisms from yeast to human. Their important contribution in different metabolic pathways is clearly visible by the severe phenotypes seen in the majority of peroxisomal diseases, where the symptoms often leads to an early death.

  6. 19. Free Volume Depth Profiling at Polymer Surfaces and Interfaces

    Author : John Algers; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymerteknik; Polymer technology; polymer interfaces; polymer surfaces; positron lifetime; free volume;

    Abstract : Pulsed low energy positron beams provide a unique and non-destructive tool to depth probe the free volume of polymers at surfaces and interfaces. Since the employment of low energy positron beams in polymer research is an emerging technique, some focus in this thesis has been on extracting methods and equations needed to interpret the experimental data.

  7. 20. Anthropogenic Radionuclides in the Arctic Ocean: Distribution and Pathways

    Author : Dan Josefsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; americium; plutonium; iodine; strontium; cesium; Sellafield; Chernobyl; global fallout; currents; shelf; ocean; radioactivity; Arctic; Ecology; Ekologi;

    Abstract : Anthropogenic radionuclide concentrations have been determined in seawater and sediment samples collected in 1991, 1994 and 1996 in the Eurasian Arctic shelf and interior. Global fallout, releases from European reprocessing plants and the Chernobyl accident are identified as the three main sources. READ MORE
