  1. 1. Prokaryotic expression of human complement regulator factor H domains and their interaction withPneumococcal surface protein PspC

    Master-uppsats, KTH/Skolan för bioteknologi (BIO)

    Författare :Nils Lindström; [2017]
    Nyckelord :complement regulator; factor H; Pneumococci; interaction; E.coli; surface protein; PspC;

    Sammanfattning : One of the oldest and most exciting questions in science is: are we alone in the universe? During the last four billion years of Earth’s history, countless organisms have inhabited almost every environmental niche on the planet, from the deepest sea to driest deserts. However, so far no extraterrestrial life has been found. LÄS MER

  3. 2. How Maasai settlements affect the grazing habits of the Common Hippopotamus (Hippopotamus amphibius) in the Maasai Mara National Reserve, Kenya

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Åsa Wengström; [2009]
    Nyckelord :hippopotamus; hippo; maasai mara; grazing habits; human wildlife relationship;

    Sammanfattning : With a growing human population as well as a changing lifestyle, the conflict of wildlife and humans is intensifying. In Kenya, Maasais and their livestock have for a long time coexisted with wildlife, but an adjustment to privately own land and cultivation might rapidly change the terms for this coexistence.

  4. 3. Nocturnal cooling : Study of heat transfer from a flat-plate solar collector

    Magister-uppsats, Fakulteten för teknik- och naturvetenskap

    Författare :Helena Johansson; [2008]
    Nyckelord :flat-plate solar collector; nocturnal radiation; convection; COMSOL Multiphysics; simulation; modelling; heat transfer; effectiveness-NTU method; heat pump; Thermia;

    Sammanfattning : This thesis investigates the possibility of using an unglazed flat-plate solar collector as a cooling radiator. The solar collector will be connected to the condenser of a heat pump and used as cooler during nighttime. Daytime the solar collector will be connected to the evaporator of the heat pump and used as heat source. LÄS MER
