  1. 1. Electromagnetic Field Induced Out-of-Equilibrium Structural Dynamics in Protein Crystals: From Picoseconds to Milliseconds

    Författare :Viktor Ahlberg Gagnér; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Terahertz radiation; low frequency vibrations; B-factors; ADP tensor; bovine trypsin; FemtoMAX; resampling; femtosecond structural dynamics; millisecond structural dynamics; LCLS; displacements; distances; photosynthetic reaction center;

    Sammanfattning : Light-induced interactions in biomolecules are strongly varying over different model systems. Most amino acids and proteins absorb ultraviolet light, but only a few with specialised chromophores or fluorophores, are able to absorb light in the visible spectrum. LÄS MER

  3. 2. Bridging the gap between computational chemistry and macromolecular crystallography

    Författare :Octav Caldararu; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein structure; X-ray crystallography; Neutron crystallography; Quantum mechanics; QM MM; Quantum refinement; Ensemble refinement; Water structure;

    Sammanfattning : Knowledge of the atomic structure of biomolecules, such as proteins, is paramount to understanding their function and interactions in the human body. For example, knowledge of the atomic structure of a target protein is crucial for developing drugs that bind strongly to it and thus help cure diverse diseases. LÄS MER

  4. 3. Quantification of mineral weathering rates in sulfidic mine tailings under water-saturated conditions

    Författare :Magdalena Gleisner; Docent Roger Herbert; Professor Emeritus Rolf Hallberg; Dr. Magnus Land; Professor Patrick Crill; Mats Åström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mine tailings; pyrite; sulfides; weathering; oxygen availability; Acidithiobacillus ferrooxidans; Earth sciences; Geovetenskap;

    Sammanfattning : Tailings are a fine-grained waste product produced during the metal recovery process. Tailings consist mostly of different silicates but also sulfides (e.g. pyrite), since 100 % metal recovery is not possible. LÄS MER

  5. 4. A Study of Different Methods for Inclusion Characterization towards On-line use during Steelmaking

    Författare :Diana Janis; Pär Jönsson; Lauri Holappa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; on-line method; PDA OES; electrolytic extraction; inclusions; clusters; nozzle clogging; secondary steelmaking;

    Sammanfattning : The interest of gaining on-line information related to non-metallic inclusions during the steelmaking process has recently increased due to the development as well as the promising results of the Pulse Distribution Analysis with Optical Emission Spectroscopy method (PDA/OES). Even though, the time from sampling to presented results on inclusions is only about 5-10 minutes, the method has also shown limitations with respect to the determination of some inclusion characteristics.

  7. 5. Regulation of the Epstein-Barr Virus Latent Membrane Protein 1 Expression

    Författare :Pegah Johansson; Göteborgs universitet; []
    Nyckelord :Gene regulation; LMP1; Epstein-Barr virus; Herpesvirus;

    Sammanfattning : Epstein-Barr virus (EBV) is a probably the most effective and successful human virus, infecting more than 90% of the world?s adult population. As with the other members of the herpesvirus family, EBV establishes latent infection in its host and persists life-long. LÄS MER
