  1. 1. Protein structure prediction Zinc-binding sites, one-dimensional structure and remote homology

    Detta är en avhandling från Stockholm : Department of Materials and Environmental Chemistry (MMK), Stockholm University

    Författare :Nanjiang Shu; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein structure prediction; zinc-binding; profile; homology detection; shape string; NATURAL SCIENCES Biology Other biology Bioinformatics; NATURVETENSKAP Biologi Övrig biologi Bioinformatik; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; Structural Chemistry; strukturkemi;

    Sammanfattning : Predicting the three-dimensional (3D) structure of proteins is a central problem in biology. These computationally predicted 3D protein structures have been successfully applied in many fields of biomedicine, e.g. family assignments and drug discovery. LÄS MER

  2. 2. Formation stability and electronic structure of surfaces and interfaces from first principles

    Detta är en avhandling från Chalmers University of Technology

    Författare :Jochen Rohrer; Chalmers tekniska högskola.; Chalmers University of Technology.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronstruktur; Electronic structure; Ytor och mellanytor; Surfaces and interfaces; Materialfysik med ytfysik; Material physics with surface physics; Alumina; graphene; graphane; density functional theory; van der Waals interaction; thin film; interface; CVD; nucleation; growth; atomic structure; electronic structure; band structure;

    Sammanfattning : This thesis deals with two closely interwoven aspects of first-principle (density functional theory) materials modeling: (1)~prediction of atomic structure & chemical composition, and (2)~prediction of electronic properties. In the first part, we focus on atomic structure (AS) and chemical composition (CC) of surface and interface systems. LÄS MER

  3. 3. LiFeSO4F as a Cathode Material for Lithium-Ion Batteries Synthesis, Structure, and Function

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Adam Sobkowiak; Uppsala universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; cathode; LiFeSO4F; tavorite; triplite; synthesis; performance; structure; coating; PEDOT; XRD; Mössbauer spectrocopy; SEM; TEM; electrochemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : In this thesis, two recently discovered polymorphs of LiFeSO4F, adopting a tavorite- and triplite-type structure, were investigated as potential candidates for use as cathode materials in Li-ion batteries. The studies aimed at enriching the fundamental understanding of the synthetic preparations, structural properties, and electrochemical functionality of these materials. LÄS MER

  4. 4. From Sequence to Structure Using predicted residue contacts to facilitate template-free protein structure prediction

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Mirco Michel; Stockholms universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein bioinformatics; protein structure prediction; contact prediction; machine learning; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

    Sammanfattning : Despite the fundamental role of experimental protein structure determination, computational methods are of essential importance to bridge the ever growing gap between available protein sequence and structure data. Common structure prediction methods rely on experimental data, which is not available for about half of the known protein families. LÄS MER

  5. 5. Human Value Structure and Emotions

    Detta är en avhandling från Göteborg : Intellecta infolog AB

    Författare :William Montgomery; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Value structure; emotions; circumplex structure; multivariate statistical methods;

    Sammanfattning : In this dissertation Shalom Schwartz’ theory of the structure of basic human values is developed. A partially new structure is proposed consisting of pairs of contrastive values (Security – Courage, Manage by yourself – Get help, Adaptation – Own will, and Prioritize yourself – Prioritize others) and non-contrastive values (Happiness, Meaningfulness, Love, Enjoyment, Respect, Deeper understanding of the world, Achievement, and Health).
