  1. 1. Conceptual metaphors in learning and teaching entropy : adopting a cognitive semantic approach in science education research

    Författare :Fredrik Jeppsson; Helge Strömdahl; Tamer Amin; Roland Kjellander; David Hammer; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Science education; thermodynamics; semantics; conceptual metaphors; Naturvetenskapernas didaktik; termodynamik; entropi; semantik; begreppsliga metaforer;

    Sammanfattning : Over the last 20 years there has been an extensive amount of research on science learning conducted from a “knowledge-in-pieces” or “resources” perspective. One of the main goals of that research has been to identify and characterize available cognitive knowledge resources that can be productive components of scientific understanding. LÄS MER

  4. 3. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi

    Författare :Edith Hammer; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inoculum; Glomalin; Fatty acids; Osmolyte; Organic matter; K; Na; Salinity; Symbiotic exchange; Phosphorus P; Carbon C; PIXE; Arbuscular mycorrhizal fungi; Rhizobium;

    Sammanfattning : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. LÄS MER
