    Abstract : The objectives of this thesis are to assess: to what degree have natural resources deteriorated in a grazing area in northern Namibia, how do perceptions of environmental change held by local stakeholders there, correspond to scientific assessments, and how do these relate to national estimates? Analysis of the process of developing national indicators for monitoring of land degradation concluded that specific indicators should be developed on national level, and in some instances even on local level as there are no universal causes of land degradation. According to farmers overgrazing and low rainfall since the early 1990s cause negative environmental changes in the study area, partly confirming findings from national monitoring. READ MORE

    Author : Anders Olsson; KTH; []
    Keywords : ;

    Abstract : Today there is growing interest in research on microfluidicsystems, e.g., for chemical analysis systems and microdosagesystems. One of the basic components in microfluidic systems ismicropumps. READ MORE

  5. 3. Phosphorylation in State Transition : Less cause more effect

    Author : Jakob Damkjaer; Jansson Stefan; Eva-Mari Aro; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photosynthesis; Photoacclimation; State Transtion; LHCII Phosphorylation; Lhcb3; Lhcb6; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Abstract : Study of the Arabidopsis thaliana knockout mutant lacking Lhcb3 (koLhcb3) have revealed a close similarity to the wild type plants. Growth rate, NPQ, qP, Φ(PSII), circular dichroism spectra, pigment composition and content of LCHII trimers have been found to be unaffected by this mutation. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Urban and Regional Studies; Urbana och regionala studier;

    Abstract : Various researchers have pointed out that avoiding further catastrophicconsequences related to the deteriorating ecological state of the planet,brought about by unsustainable production and consumption patterns,requires not only technological innovation and efficiency in productionprocesses, but also absolute reductions in energy and material use (i.e. READ MORE

  7. 5. More or Less IgE : Therapeutic Vaccines, Adjuvants and Genes and Their Effect on IgE Levels

    Author : Anna Ledin; Lars Hellman; Kjell-Olov Grönvik; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; IgE; Immunoglobulin; Atopic allergy; Vaccine; Adjuvant; Dog; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : Immunoglobulin E (IgE) is an important mediator in atopic allergies. This thesis describes the development of a therapeutic vaccine against IgE and its effects in rats and dogs. The development of an assay to determine IgE levels in dogs, and the finding of a chromosome region in rats that affects IgE levels are also reported. READ MORE
