  1. 1. Cooperation and conflict over the struggle to reproduce in harsh environments : An experimental field study on ostriches

    Författare :Julian Melgar; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; social; grupp; konkurrens; konflikt; fusk; värme; stress; tolerans; complexitet; variation; social; group; competition; conflict; cheating; heat; stress; tolerance; complexity; variation;

    Sammanfattning : People are used to hearing that evolution is about the survival of the fittest. Theyimagine a world full of bullies that ruthlessly fight their way to the top in the struggle for life, leaving the weak behind. But this doesn’t need be the case. LÄS MER

  3. 2. Spray Processes in Optical Diesel Engines - Air-Entrainement and Emissions

    Författare :Clement Chartier; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel; Combustion; Soot; UHC; Injections; Lift-off length; air-entrainement;

    Sammanfattning : Internal combustion engines have been an important technological field for more than a century. It has had an important impact on society through improved transportation and industrial applications. LÄS MER

  4. 3. The conserved methionines in the chloroplast small heat shock protein - Role in chaperone-substrate interactions and effects of methionine sulfoxidation on chaperone activity

    Författare :Niklas Gustavsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biochemistry; oxidative stress; thermostability; temperature stress; stress tolerance; sHsp; protein aggregation; molecular chaperone; Heat stress; methionine sulfoxidation; Biokemi; metabolism; Plant biochemistry; Växtbiokemi;

    Sammanfattning : The chloroplast-localized small heat shock protein (sHsp) Hsp21 belongs to the family of alpha-crystallin like sHsps which form large oligomeric structures and protect partly unfolded aggregation-prone proteins against aggregation. The main focus for this thesis has been on the highly conserved methionines in Hsp21. LÄS MER

  5. 4. Soil microbial responses to mild winters and seasonal change

    Författare :Johanna Birgander; Biodiversitet; []
    Nyckelord :Arbuscular mycorrhizal fungi AMF ; RESPIRATION; Stable isotope; Fungal growth; PLFA; NLFA; Microbial community composition; bacterial growth; Aboveground-belowground interactions; Temperature adaptation; Climate change;

    Sammanfattning : The aim with this thesis work was to study microorganisms response to milder winters, different seasons, and altered temperature. Winter warming treatments were established in a semi-natural temperate grassland, simulating mild winters for two years. LÄS MER

  7. 5. Inside Pulsating White Dwarfs: Clues from time-resolved spectroscopy

    Författare :Rubina Kotak; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pulsating white dwarfs; convection; asteroseismology; Astronomi; Astronomy; spectroscopy; Fysicumarkivet A:2002:Kotak;

    Sammanfattning : Several analyses using time-resolved optical spectrocopy of pulsating white dwarfs are presented. The data have been put to a number of uses. First, line-of-sight velocities associated with the pulsations have been measured in three hydrogen-atmosphere white dwarfs (DAVs), bringing the total number of such measurements up to five. LÄS MER
