  1. 1. Improving Stress Tolerance in Industrial Saccharomyces cerevisiae Strains for Ethanol Production from Lignocellulosic Biomass

    Författare :Valeria Wallace; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; lignocellulose; ethanol; inhibitors; temperature; stress tolerance;

    Sammanfattning : The present work was aimed at developing industrial S. cerevisiae strains with improved tolerance to two types of stressors encountered during the fermentation of lignocellulosic biomass that affect ethanol yield and productivity, namely hydrolysate-derived inhibitors and high temperature, and at understanding the response of yeast and mechanisms of adaptation to such stressors.

  3. 2. Landskap på jorden och i drömmen. Studier i Folke Isakssons lyrik

    Författare :Håkan Sandgren; Litteraturvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; General and comparative literature; the aesthetics of the post-war era; modernist poetry; lyrical tropes and clichés; intertextuality; the metaphor of the journey; poetry of place; 20th century Swedish poetry; literature criticism; literary theory; Allmän och jämförande litteratur; litteraturkritik; litteraturteori;

    Sammanfattning : My study focuses on the analysis of single poems chosen as paradigmatic of Fole Isaksson's style and poetic vision. This approach is grounded in the belief that there is a certain thematic unity to Isaksson's lyric output, a unity which stems from the poet's constant preoccupation with the relations between the speaker of a poem and external nature, i.

  4. 3. Island biogeography and population divergence in the Skyros wall lizard

    Författare :Anna Runemark; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Podarcis gaigeae; inbreeding; predation release; polymorphism; island gigantism; the island rule; genetic drift; sexual selection; natural selection; island biology; Evolution;

    Sammanfattning : Islands are cradles for new biodiversity and provide natural laboratories for the study of population divergence. In my thesis, I investigated the role of different evolutionary processes in the population divergence in the Skyros wall lizard (Podarcis gaigeae), a species where islet populations have strongly diverged morphologies.
