  2. 1. Structural Studies of Flexible Biomolecules and a DNA-binding Protein

    Author : Tariq Massad; Pål Stenmark; Cheryl Arrowsmith; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Maximum entropy; motilin; DNA-binding proteins; Karplus equation; disaccaride; direct repeats; Structural biology; Strukturbiologi; Biophysics; biofysik;

    Abstract : The knowledge of the three-dimensional structures of proteins and polypeptides is essential to understand their functions. The work shown in this thesis has two objectives. READ MORE

  4. 2. Fractional Calculus and Linear Viscoelasticity in Structural Dynamics

    Author : Mikael Enelund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; linear viscoelasticity; convolution integrals; anisotropy; structural modeling; finite elements; material damping; time integration; internal variables; relaxation; fractional calculus; creep; Mittag-Leffler functions;

    Abstract : The use of linear viscoelasticity together with fractional calculus in time-domain structural modeling is studied. Both constitutive and structural aspects are investigated. READ MORE

  5. 3. Structural integrity of prestressed nuclear reactor containments

    Author : Patrick Anderson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel liner; reliability; relaxation; shrinkage; creep; loss of prestress; tendon; Nuclear; containment; design pressure; Construction technology; Anläggningsteknik;

    Abstract : A nuclear power plant is provided with an extensive defense intended to prevent radioactive discharge in case of a reactor accident. This defense is built up of several independent safety barriers, where the reactor containment constitutes the last barrier to the environment. READ MORE

  6. 4. Probing Dynamics of Oligosaccharides by Interference Phenomena in NMR Relaxation

    Author : Leila Ghalebani; Jozef Kowalewski; Norbert Mueller; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NMR; sugars; oligosaccharides; carbon-13 relaxation; cross-correlated relaxation; molecular dynamics; internal motion; random jumps; PRE; paramagnetic relaxation; Chemistry; Kemi; fysikalisk kemi; Physical Chemistry;

    Abstract : Oligosaccharides (carbohydrates) are a large class of biological molecules that are important as energy sources in the human body and have enormously varied biological functions. It is generally believed that biological activities of carbohydrates are related to their internal dynamics. READ MORE

  7. 5. Computational Methods in Conceptual Structural Design

    Author : Vedad Alic; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conceptual design; conceptual structural design; ground-borne vibrations; form finding; optimization; dynamic relaxation; graphic statics; reciprocal figures; strut-and-tie; finite element method; isogeometric analysis; NURBS; CAD; numerical modelling;

    Abstract : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. READ MORE
