  1. 1. Remote sensing of supra-glacial lakes on the west Greenland Ice Sheet

    Författare :A. Malin Johansson; Ian A. Brown; Peter Jansson; Johan Kleman; Andreas Ahlstrøm; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supra-glacial lakes; Greenland Ice Sheet; Ice melting; Remote sensing; SAR; MODIS; Time-series analysis; Physical Geography; naturgeografi;

    Sammanfattning : The Greenland Ice Sheet is the largest ice sheet in the northern hemisphere. Ongoing melting of the ice sheet, resulting in increased mass loss relative to the longer term trend, has raised concerns about the stability of the ice sheet. Melt water generated at the surface is temporarily stored in supra-glacial lakes on the ice sheet. LÄS MER

  3. 2. Monitoring lithospheric motions by Satellite geodesy

    Författare :Nureldin A. A. Gido; Mohammad Bagherbandi; Lars E. Sjöberg; Faramarz Nilfouroushan; Hossein Nahavandchi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geodesi; Geodesy;

    Sammanfattning : Understanding of global and local Earth’s dynamic processes is of great importance to the Earth’s system knowledge, human life, and sustainability goals (e.g. climatic change and geo-hazard assessment, etc.). LÄS MER

  4. 3. Infant gut microbiota, immune responses and allergic disease during childhood

    Författare :Maria A. Johansson; Eva Sverremark-Ekström; Christina West; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; immunologi; Immunology;

    Sammanfattning : The early-life microbiota is important for postnatal immune maturation and implied in immune mediated diseases. The aim of this work was to study specific species of bacteria in the gut microbiota and relate them to immune function and allergic disease during childhood. LÄS MER

  5. 4. Temporal and spatial dynamics in subarctic peat plateaus and thermokarst lakes

    Författare :A. Britta K. Sannel; Peter Kuhry; Peter Jansson; Ian A. Brown; Serge Payette; Stockholms universitet; []
    Nyckelord :Peatlands; permafrost; subarctic; peat plateau; thermokarst lake; macrofossil analysis; carbon nitrogen ratio; peat accumulation; carbon accumulation; remote sensing; binary encoding; time-series analysis; Physical Geography; naturgeografi;

    Sammanfattning : Permafrost peatlands are widespread at high northern latitudes and are important soil organic carbon reservoirs. A future warming in these areas, as suggested by global climate models, can cause thawing and increased ground subsidence (thermokarst), resulting in changes in surface hydrology and ecosystem functioning.

  7. 5. Structural, thermal and thermodynamic properties of some Ln-Pd oxides and their behaviour as catalyst precursors

    Författare :Martin Andersson; A.R. West; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : The structural, thermal and thermodynamic properties of some Ln-Pd oxides of the Ln4Pd07 type are presented. The main results are; (i) Reduction of Ln4Pd07, either ex-situ by CO or in-situ by a synthetic car exhaust gas, results in a materialwith catalytic activity for car exhaust gas clean-up reactions.
