  1. 1. Structural, Kinetic and Thermodynamic Aspects of the Crystal Polymorphism of Substituted Monocyclic Aromatic Compounds

    Författare :Michael Svärd; Åke Rasmuson; Hugo Meekes; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymorphism; crystallization; thermodynamics; kinetics; nucleation; crystallography; solubility; phase equilibria; polymorphic transformation; solution history; metastable zone; classical theory of nucleation; two-step theory of nucleation; cluster; crystal structure prediction; lattice energy; molecular mechanics; force field; electrostatic potential; potential energy hypersurface; m-aminobenzoic acid; m-hydroxybenzoic acid; Chemical engineering; Kemiteknik;

    Sammanfattning : This work concerns the interrelationship between thermodynamic, kinetic and structural aspects of crystal polymorphism. It is both experimental and theoretical, and limited with respect to compounds to substituted monocyclic aromatics. LÄS MER

  3. 2. A Theory of Parametric Polymorphism and an Application

    Författare :Jean-Philippe Bernardy; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis revisits the well-known notion of parametric polymorphismin the light of modern developments in type-theory. Additionally,applications of parametric polymorphism are also presented.The first part of the thesis presents a theoretical investigation ofthe semantics of parametric polymorphism of and within type-theorieswith dependent types.

  4. 3. Computational Studies of Poly(vinylidene fluoride)

    Författare :Martin Bohlén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; β-phase; Piezoelectricity; PVDF; Molecular modeling;

    Sammanfattning : Poly(vinylidene fluoride) (PVDF) is a versatile material with numerous applications, both potential and realized, in many industrial sectors. The extent of applications, ranging from cable and wire products, to sensors for the monitoring of respiration and heart-rate in medicine, indicates on the level of interest the materials science community has for this material.

  5. 4. Nasopharyngeal carcinoma and Epstein-Barr virus

    Författare :Li-Fu Hu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NPC; EBV; EBNAs; LMPI; LMP2; Tumorigenicity; Immunogenicity;

    Sammanfattning : Nasopharyngeal carcinoma (NPC) is the most common tumor in southern China and also quite frequent among the Eskimos and in Alaska. NPC is invariably associated with Epstein-Barr virus (EBV). LÄS MER

  7. 5. Function, expression and polymorphism of human alcohol dehydrogenase 3/glutathionedependent formaldehyde dehydrogenase

    Författare :Jesper Hedberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alcohol dehydrogenase 3 (ADH3), identical to glutathione-dependent formaldehyde dehydrogenase, plays a vital role in the defense against formaldehyde through the activity for the spontaneously formed adduct between formaldehyde and glutathione, Shydroxymethylglutathione (HMGSH). ADH3 may also participate in the metabolism of Snitrosylated glutathione, GSNO. LÄS MER
