  2. 1. Greenhouse gas emission from tropical reservoirs : Spatial and temporal dynamics

    Author : Annika Linkhorst; Sebastian Sobek; Frédéric Guérin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; methane; carbon dioxide; climate; carbon cycle; lake; limnology; inland water;

    Abstract : The emission of methane (CH4) and carbon dioxide (CO2) from reservoirs has been estimated to make up for about 1.3% of the global anthropogenic greenhouse gas emission. The impoundment of a river leads to the accumulation of sediment that is brought in from inflowing rivers, and the sediment organic matter is degraded to CH4 and CO2. READ MORE

  4. 2. Carbon trace gas dynamics in subarctic lakes

    Author : Joachim Jansen; Patrick Crill; Andreas Lorke; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lakes; methane; carbon dioxide; fluxes; gas transfer; proxy; climate change; geokemi; Geochemistry;

    Abstract : Northern lakes are important sources of greenhouse gases carbon dioxide and methane to the atmosphere. Emissions are expected to increase as the climate continues to warm. Even so, lake carbon budgets are currently poorly constrained. This is in part because of a limited understanding of the processes that govern the flux. READ MORE

  5. 3. Exploring the Molecular Dynamics of Proteins and Viruses

    Author : Daniel Larsson; David van der Spoel; Modesto Orozco; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; virus dynamics; capsid dissolution; satellite tobacco necrosis virus; satellite tobacco mosaic virus; virus genome structure; gas phase protein structure; water layer; micelle embedded protein; membrane protein; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Abstract : Knowledge about structure and dynamics of the important biological macromolecules — proteins, nucleic acids, lipids and sugars — helps to understand their function. Atomic-resolution structures of macromolecules are routinely captured with X-ray crystallography and other techniques. READ MORE

  6. 4. Molecular gas in the galaxy M83 : Its distribution, kinematics, and relation to star formation

    Author : Andreas Andersson Lundgren; Hans Olofsson; John Whiteoak; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular gas; Galaxies; Galaxies individual: M83; Star formation; Galactic dynamics; Astronomy and astrophysics; Astronomi och astrofysik;

    Abstract : The barred spiral galaxy M83 (NGC5236) has been observed in the 12CO J=1–0 and J=2–1 millimetre lines with the Swedish-ESO Submillimetre Telescope (SEST). The sizes of the CO maps are 100×100, and they cover the entire optical disk. The CO emission is strongly peaked toward the nucleus. READ MORE
