  1. 41. Classical and Quantum Descriptions of Proteins, Lipids and Membranes

    Författare :Richard Tjörnhammar; Olle Edholm; Sagar Pandit; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum corrections; Coordination structure; Polarisation; Phase transitions; Kelvin differential equation; Line tension; Elastic membrane models; Molecular particle models; Zinc binding; Cholesterol and Phospholipids; Biological Physics; Biologisk fysik;

    Sammanfattning : In this thesis the properties of proteins and membranes are studied by molecular dynamics simulations. The subject is decomposed into parts addressing free energy calculations in proteins, mechanical inclusion models for lipid bilayers, phase transitions and structural correlations in lipid bilayers and atomistic lipid bilayer models.

  3. 42. Density Functional Theory in Computational Materials Science

    Författare :Jorge Mario Osorio Guillén; Rajeev Ahuja; Börje Johansson; Bruce N. Harmon; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Density Functional Theory; High Pressure; Phase Transitions; Elastic Properties; Lithium Batteries; Dilute Magnetic Semiconductors; Fysik; Physics; Fysik;

    Sammanfattning : The present thesis is concerned to the application of first-principles self-consistent total-energy calculations within the density functional theory on different topics in materials science. Crystallographic phase-transitions under high-pressure has been study for TiO2, FeI2, Fe3O4, Ti, the heavy alkali metals Cs and Rb, and C3N4. LÄS MER

  4. 43. The diffusion of biogas systems in Brazil

    Författare :Hanna Zanatta; Wisdom Kanda; Olof Hjelm; Thomas Magnusson; Hans Hellsmark; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Socio-technical interactions; Sustainability transitions; Global South;

    Sammanfattning : Brazil is one of the largest economies in the Global South. Because of the country’s strong agribusiness and large population, it has a huge potential for biogas production that has yet to be realized. LÄS MER

  5. 44. The Charm of Excited Glue : Charmonium in e+e– and ppbar collisions

    Författare :Agnes Lundborg; Ulrich Wiedner; Helmuth Koch; Uppsala universitet; []
    Nyckelord :Physics; hadron; charmonium; PANDA; antiproton; annihilations; spin-parity exotics; gluonic excitations; BES; hybrid; glueball; resonances; radiative decays; electromagnetic transitions; Fysik;

    Sammanfattning : This thesis treats the mass range of charmonium states and excited gluonic fields in two experiments, BESII and PANDA, and outlines a phenomenological model that connects them.In BESII, e+e– form a charmonium initial state, which is utilised as a source for secondary particles.

  7. 45. Regime Shifts in the Anthropocene

    Författare :Juan Carlos Rocha; Garry Peterson; Reinette Biggs; Örjan Bodin; Kevin Noone; Sarah Cornell; Ingo Fretzer; Steven Lade; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; regime shifts; critical transitions; network analysis; dynamic tipping points; Sustainability Science; vetenskap om hållbar utveckling; Systems Ecology; systemekologi;

    Sammanfattning : Regime shifts are large, abrupt and often hard to reverse changes in the function and structure of socal-ecological systems. These regime shifts have been documented in a broad range of systems and scales both in marine, terrestrial and polar ecosystems. LÄS MER
