  1. 1. Studies on cell wall-attached proteins of Streptococcus pyogenes

    Författare :Magnus Rasmussen; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insertion sequence; phase variation; collagen-like; alpha2-macroglobulin; pattern; virulence; surface protein; Stretococcus pyogenes; cell wall-attached protein; Clinical biology; Klinisk biologi;

    Sammanfattning : Cell wall-attached proteins (CWPs) are important for the virulence of Gram-positive bacteria, but are also targets for the host immune system. CWPs have a conserved COOH-terminal region, responsible for cell wall-sorting. A pattern based on this conserved region was developed. LÄS MER

  3. 2. Attached Bacterial Communities in Lakes – Habitat-Specific Differences

    Författare :Ann-Louise Haglund; Lars Tranvik; Helmut Fischer; Bengt Boström; Erik Törnblom; Paul del Giorgio; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; bacteria; freshwater; sediment; epiphyton; bacterioplankton; metabolically active; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : For many years, the importance of microorganisms attached to surfaces in littoral zones and wetlands has been disregarded when describing aquatic ecosystem dynamics. Supporting evidence is scarce but convincing that these microbial communities are not only very productive but can often serve as major regulators of nutrient and carbon dynamics in many freshwaters.

  5. 4. Studies on the alpha-recoil implantation of 214Pb and 210Pb in glass surfaces,Implications for retrospective radon measurements

    Författare :Birgitta Roos; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; unattached activity; attached activity; retrospective radon measurement; long-lived radon progenies; short-lived radon progenies; deposition velocity; implantation; 222Rn; glass surface; etching; simulation; Nuclear physics; Kärnfysik;

    Sammanfattning : Glass sheets are often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. The implanted activity is influenced by a variety of different environmental conditions. LÄS MER

  7. 5. Shape from shading, colour constancy, and deutan colour vision deficiencies

    Författare :Torbjörn Jakobsson; Karl-Arne Gustafsson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; 3-D perception; ambiguous figures; attached shadows; cast shadows; colour constancy; colour vision deficiency; deuteranomaly; deuteranopia; shape- from-shading;

    Sammanfattning : Four studies including ten experiments adresses interrelations between some major and classical issues in visual perception: 3-D perception, colour constancy, colour perception and colour vision deficiencies. The main experimental paradigm to investigate the issues is within that of simulated shape from shading. LÄS MER
