    Sammanfattning : The strength of efficient metal-free catalysis will be examined in this thesis. Efforts towards more sustainable processes will be demonstrated through implementation of strategies that meet several of the 12 principles of Green Chemistry. LÄS MER

  3. 2. Crystallization of Metal Fluoride Hydrates from Mixed Acid Solutions

    Författare :Kerstin Forsberg; Åke Rasmuson; Alison Lewis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crystallization; crystal growth; b-FeF3.3H2O; iron fluoride trihydrate; CrF3.3H2O; pickling; pickle bath; hydrofluoric acid; nitric acid; stainless steel; Chemical engineering; Kemiteknik;

    Sammanfattning : In this work crystal growth and nucleation of b-FeF3×3H2O and crystallization of chromium (III), iron (III) and nickel (II) fluoride hydrates from mixed acid (1-3 mol/kg HNO3 and 1-6 mol/kg free HF) have been investigated. The solubility of b-FeF3×3H2O has been determined in solutions of different hydrofluoric acid (1-7mol/ kg) and nitric acid (0-7mol/ kg) concentrations at 30, 40 and 50°C. LÄS MER

  4. 3. Malory and Authorship: A Study of an Irresolvable Debate

    Författare :Marie Wallin; Engelska; []
    Nyckelord :HUMANIORA; HUMANITIES; medieval literature; Eugène Vinaver; C.S. Lewis; textual criticism; Arthurian literature; Sir Thomas Malory; Le Morte Darthur; William Caxton; authorship;

    Sammanfattning : This thesis examines the scholarly study of Sir Thomas Malory’s Le Morte Darthur, especially the way in which the field has been shaped by the discovery of the Winchester MS in 1934. Owing to the complex relationship between the manuscript and the printed edition of 1485, both contradictory and co-dependent, Le Morte seems to invite a number of narratives regarding its origins and originality while simultaneously foreclosing definitive resolution.

  5. 4. Scholarship and Mythopoeia : The ideas of language and myth in the works of Owen Barfield, C.S. Lewis and J.R.R. Tolkien

    Författare :Maria Kuteeva; Tony Crowley; Thomas Shippey; Department of English and American Studies University of Manchester; []
    Nyckelord :HUMANIORA; HUMANITIES; language; myth; philology; Languages and linguistics; Språkvetenskap; English; engelska;

    Sammanfattning : This thesis examines the views adopted by Barfield, Lewis and Tolkien on the phenomena of language and myth as discussed in their academic writing and fiction. Part I (Chapters I and II) focuses on the study of language. LÄS MER

  7. 5. Minkowski Measure of Asymmetry and Minkowski Distance for Convex Bodies

    Författare :Qi Guo; Sten Kaijser; Marek Lassak; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Matematisk analys; Mathematical analysis; Analys;

    Sammanfattning : This thesis consists of four papers about the Minkowski measure of asymmetry and the Minkowski (or Banach-Mazur) distance for convex bodies.We relate these two quantities by giving estimates for the Minkowski distance in terms of the Minkowski measure. LÄS MER
