  1. 11. The Competition for Forest Raw Materials in the Presence of Increased Bioenergy Demand : Partial Equilibrium Analysis of the Swedish Case

    Författare :Elina Bryngemark; Patrik Söderholm; Anne Toppinen; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; bioenergy; biodiversity; partial equilibrium model; forest raw materials; market competition; Sweden; Economics; Nationalekonomi;

    Sammanfattning : Growing energy use and greenhouse gas emissions have implied an increased attention to the development of renewable energy sources. Bioenergy from forest biomass is expected to be one of the cornerstones in reaching renewable energy targets, especially in forest-rich countries such as Sweden. LÄS MER

  3. 12. The Economics of Biofuel Development : Policy Incentives and Market Impacts

    Författare :Elina Bryngemark; Patrik Söderholm; Jussi Lintunen; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Sammanfattning : This thesis examines the economics of biofuel development by studying the forest raw material market impacts of increased biofuel production, as well as the role of specific policy incentives. Paper [I] presents an economic assessment of two different developments – both implying an increased demand for forest ecosystem services – and how these could affect the competition for forest raw materials.

  4. 13. Transition metal-catalyzed reduction of carbonyl compounds : Fe, Ru and Rh complexes as powerful hydride mediators

    Författare :Elina Buitrago; Hans Adolfsson; Robert Morris; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Asymmetric catalysis; amino acid; N-heterocyclic carbene; iron; ruthenium; rhodium; mechanistic investigation; kinetic study; asymmetric transfer hydrogenation; hydrosilylation; organisk kemi; Organic Chemistry;

    Sammanfattning : A detailed mechanistic investigation of the previously reported ruthenium pseudo-dipeptide-catalyzed asymmetric transfer hydrogenation (ATH) of aromatic ketones was performed. It was found that the addition of alkali metals has a large influence on both the reaction rate and the selectivity, and that the rate of the reaction was substantially increased when THF was used as a co-solvent.

  5. 14. Modernismens bilder : Den moderna bilderboken i Norden

    Författare :Elina Druker; Boel Westin; Nina Christensen; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Children’s literature; picture books; modernism; literary history; illustration; artists’ books; intermediality; Literature; Litteraturvetenskap; litteraturvetenskap; History of Literature;

    Sammanfattning : This doctoral thesis is based on a survey of an extensive corpus of Nordic picture books and illustrated children’s books from mainly the 1940’s and 1950’s. It discusses different aspects of the position of the child, children’s culture and children’s literature in the works of the young generation of artists during this era. LÄS MER
