  4. 2. Excitation and Ground-State Properties of Natural and Modified Nucleic Acid Bases

    Author : Anders Holmén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ab initio; linear dichroism; DFT; transition moment; tautomerism; structure; IR; spectra; DNA bases;

    Abstract : The nucleic acid bases are the carriers of genetic information in DNA and RNA. They are also the main chromophores of nucleic acids and determine their optical properties and sensitivity to UV radiation. READ MORE

  5. 3. Electronic Control of Flexural Nanowire Vibrations

    Author : Fabio Santandrea; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoelectromechanical systems; Carbon nanotubes; Coulomb blockade; Shuttle instability; Ground-state cooling;

    Abstract : “Nanoelectromechanical systems” (NEMS) are nanometer-sized mechanical structures coupled to electronic devices of comparable size. The coupling between mechanical and electronic degrees of freedom, combined with their mesoscopic size, provide these systemswith some unique properties that make them interesting from both the fundamental and technological point of view.

  6. 4. Structure of the Ground State of the Electroweak Gauge Theory in a Strong Magnetic Field

    Author : Ola Törnkvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis deals with the construction of perturbative methods for analyzing the phase transition of the electroweak gauge theory in a strong magnetic field at zero temperature. The first part is a self-contained description of the methods and results. The second part contains the articles on which the first part is based. READ MORE

  7. 5. Homotrimeric dUTPases : Principles of Catalysis and Inhibitor Design

    Author : Lorena Gonzalez Palmén; Jan Kvassman; Dolores Gonzalez-Pacanowska; Högskolan i Kalmar; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dUTPases; kinetics; ground state destabilization; inhibitors; Biochemistry; Biokemi; Natural Science; Naturvetenskap;

    Abstract : The ubiquitous enzyme dUTPase hydrolyzes dUTP into dUMP and pyrophosphate, preventing DNA fragmentation and cell death due to accumulation of dUTP. Inhibitors of dUTPase could serve as drugs in the treatment of cancers and infectious diseases. This thesis presents five studies. READ MORE
