  1. 1. Bokkonstnären Akke Kumlien : tradition och modernitet, konstnärsidentitet och konstnärsroll

    Författare :Magdalena Gram; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Kumlien; Akke; 1884-1949; Bokkonst; Sverige; 1900-talet; Bokkonstnärer; Typografi; Grafisk formgivning;

    Sammanfattning : The purpose of this dissertation is to illuminate the relationship between the book artist Akke Kumlien (1884-1949) and various ideas about the design of books and printed letters, and to describe the evolution of Kumlien’s artistic identity and professional role. The study is based partly on primary and secondary sources and, to a greater extent, on books as objects, and in particular books published by Norstedts Förlag roughly between 1915 and 1950. LÄS MER

  5. 4. Advanced NMR techniques for structural elucidation in medicinal chemistry

    Författare :Hermina Wieske; Máté Erdélyi; Mikael Akke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The nuclear Overhauser effect (NOE) is an NMR phenomenon that can reveal spatial proximity between two atoms. It has found applications in organic chemistry and structural biology including natural product chemistry, organic synthesis, medicinal chemistry, macromolecular structure elucidation and protein-ligand interactions.
