  1. 6. Factors Affecting the Distribution of Rocky-Shore Macroalgae on the Swedish Coast : Morphological, Physiological, Reproductive and Genetic Aspects

    Författare :Gustav Johansson; John Raven; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : The aim of this thesis was to examine factors affecting the distribution of macroalgal species both vertically (depth zonation) and geographically along the Baltic Sea salinity gradient. Interactions between the physical environment and basic biological traits of the algae are emphasised. LÄS MER

  3. 7. Afterload system design for functional donor heart assessment

    Författare :Harry Pigot; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physiological modelling; cardiac afterload; heart assessment; working heart; simulation; control of physiological and clinical variables;

    Sammanfattning : Heart transplantation is a life-saving procedure for patients with end-stage heart failure. However, conservative acceptance criteria result in most donated hearts being discarded. Enabling clinicians to assess heart function after organ procurement can pave the way for the safe use of hearts that are currently rejected. LÄS MER

  4. 8. Physiological status of bacteria used for environmental applications

    Författare :Ninwe Maraha; Janet K. Jansson; Charlotta Edlund; Soren J. Sorensen; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Several bacteria have properties of interest for biotechnological applications, such as bioremediation of pollutants and biocontrol of plant pathogens. In order to perform their intended tasks in the environment the cells need to remain viable and active. LÄS MER

  5. 9. Physiological integration and morphological plasticity in extensive clonal plants

    Författare :Tina D'Hertefeldt; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant ecology; Maianthemum; Carex; Clonal plants; tracers; Växtekologi;

    Sammanfattning : Clonal plants show a large variation in physiological integration, i.e. the translocation of resources among ramets within the clone. LÄS MER

  7. 10. Endogenous kynurenic acid and schizophrenia : physiological and pharmacological aspects

    Författare :Lilly Schwieler; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Kynurenic acid is a glutamate receptor antagonist with a preferential action at the glycine/Dserine site of the N-methyl-D-aspartic acid (NMDA) receptor. The compound is a metabolite of tryptophan and is synthesized in astrocytes. LÄS MER
