  1. 21. DNA-Complexes with Drugs and Proteins

    Författare :Louise Fornander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Circular Dichroism; Linear Dichroism; Minor groove binder; DNA strand exchange; HsRad51; Isothermal Titration Calorimetry; Hoechst 33258;

    Sammanfattning : DNA is fundamental for all living cells; the DNA holds the genetic code, which is more or less the instruction book for how all cells are built and function. Several diseases are also linked to DNA, emerging either from a mutation in our genome, which could result in a malfunctioning protein, or that the transcription of genes is somehow affected by structural changes in the DNA, induced by mutations or DNA binding molecules.

  3. 22. Van der Waals Interactions in Density Functional Theory

    Författare :Erika Hult; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; van der Waals interaction; exchange-correlation energy; adhesion; intermolecular forces; physisorption; density functional theory;

    Sammanfattning : Density functional theory is a very important method for calculating ground-state properties for atoms, molecules and solids. Albeit exact in principle, its implementation requires an approximation for the so-called exchange-correlation energy. LÄS MER

    Sammanfattning : The objective of this dissertation is literature discussion as a learning activity in school. The aim is to examine the conditions under which literature discussions may help students to develop their reception of a commonly read text, and to examine whether, and how, the discussions may provide the students with opportunities to learn more about, or to develop specific attitudes or perspectives towards, literary reading in general.

  5. 24. Lignin Model Compounds: Synthesis, Stereochemistry and Acidolysis

    Författare :Shiming Li; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boric acid complexes; Arylglycerol b-aryl ethers; stereochemistry; 3-Diaryl-2-propen-1-ols; 1; Phenylcoumarans; lignin model compounds; acidolysis; ion-exchange chromatography; 3-propanediols; 2-Diaryl-1; 2; X-ray crystallography;

    Sammanfattning : Lignin model compounds representative of structural elements in lignin of the b-1, b-5, b-O-4, cinnamaldehyde and cinnamyl alcohol types were synthesized. erythro-Forms of b-1 models of the 1,2-diaryl-1,3-propanediol type were prepared by BF3-catalyzed rearrangement of chalcone epoxides and subsequent reduction of the rearrangement products with NaBH4.

  7. 25. Essays on the interaction between regulation and technology : Understanding agency and context through multiple levels of inquiry

    Författare :Rasmus Nykvist; Christina Öberg; Mirko Ernkvist; Christian Sandström; Lars Engwall; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Institutional Entrepreneurship; Technological Transformation; Regulation; Historical Methods; Stockholm Stock Exchange;

    Sammanfattning : A key challenge for implementing pioneering regulatory and technological change includes overcoming regulatory constraints and resistance from vested interest groups in favor of the status quo. This is a compilation dissertation comprising five papers and one covering paper that aims to describe and explain the interaction between agency and context under conditions of combined technological and regulatory change through multiple levels of inquiry.
