  3. 7. Trace metals in the atmosphere : the wet deposition of trace metals : the selenium cycle

    Författare :Howard B. Ross; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Cd, Cu, Fe, Mn, Pb and Zn concentrations in wet deposition have been monitored in Sweden since the autumn of 1983. Concentrations of these elements are highest in southern Sweden and decrease northward. Examination of enrichment factors, relative to crustal material, indicate that the major source of Cd, Cu, Pb and Zn is anthropogenic emissions. LÄS MER

  4. 8. Monitoring climate and plant physiology using deuterium isotopomers of carbohydrates

    Författare :Angela Augusti; Jürgen Schleucher; Vaughan Hurry; Howard Griffiths; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate reconstruction; deuterium; elevated CO2; isotopomer; nuclear magnetic resonance; photorespiration; tree-ring cellulose.; Plant physiology; Växtfysiologi;

    Sammanfattning : Climate is changing and it is certain that this change is due to human activities. Atmospheric greenhouse gases have been rising in an unprecedented way during the last two centuries, although the land biosphere has dampened their increase by absorbing CO2 emitted by anthropogenic activities.

    Sammanfattning : Background: The negative effects of air pollution on morbidity and mortality have been known since the mid 20th century. The two most well known examples are the Meuse Valley disaster in the 1930’ies and the London black fog in December 1952. LÄS MER

  7. 10. Dynamic protein trafficking of the nuclear membrane and in peroxisomes

    Författare :Charlotta Buch; Einar Hallberg; Howard J. Worman; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The cell nucleus is enclosed by the nuclear envelope (NE), a double lipid membrane separating the nucleoplasm from the cytoplasm. Transport of macromolecules between the nucleus and the cytoplasm takes places through nuclear pore complexes (NPCs) in a selective and energy dependent manner. LÄS MER
