  2. 1. Modelling Approaches to Molecular Systems Biology

    Author : David Fange; Måns Ehrenberg; Johan Elf; Terence Hwa; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stochastic reaction-diffuion kinetics; antibiotic drugs; efflux pumps; amino acid biosynthesis; Min-system; rRNA operon; transcription; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : Implementation and analysis of mathematical models can serve as a powerful tool in understanding how intracellular processes in bacteria affect the bacterial phenotype. In this thesis I have implemented and analysed models of a number of different parts of the bacterium E. coli in order to understand these types of connections. READ MORE

  4. 2. Interactions in aqueous salt solutions : Atomistic modelling versus experiment

    Author : Vidar Aspelin; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistisk mekanik; molekylär modellering; MD simuleringar; MC simuleringar; statistical mechanics; molecular simulation; MD simulations; MC simulations; Kirkwood-Buff theory; Hofmeister series;

    Abstract : The research in this thesis investigates how atoms and molecules constituting aqueous salt solutions interact using computational approaches, namely Monte Carlo simulations and molecular dynamics simulations. In the first paper, an atomistic model was developed for aqueous solutions of sodium thiocyanate and potassium thiocyanate (NaSCN and KSCN). READ MORE

  5. 3. Small and Large, Charged Molecules in Solution and at Interfaces

    Author : Giulio Tesei; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular modeling; MD simulations; statistical mechanics; SAXS; QCM-D; Hofmeister series; amyloid fibril; lipid bilayer; cell-penetrating peptide; molekylär modellering; MD simuleringar; MC simuleringar; statistisk mekanik; SAXS; QCM-D; amyloidfibriller; cellmembran; cellpenetrerande peptider;

    Abstract : The influence of small and large, charged molecules on the properties of aqueous interfaces has important implications in chemistry, biology, and medicine. For example, at the surface of marine aerosols, the presence of halide anions and tropospheric gases gives way to multiphase chemical reactions affecting climate and air quality. READ MORE

  6. 4. Modeling of inorganic ions in aqueous solution

    Author : Vidar Aspelin; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molekylsimulering; statistisk mekanik; termodynamik; oorganiska joner; vattenlösningar; Kirkwood-Buff-teori; beräkningar av fri energi; molecular simulation; statistical mechanics; thermodynamics; inorganic ions; aqueous solutions; Kirkwood-Buff theory; free energy calculations;

    Abstract : Essentially all chemical processes and reactions occurring in the environment take place in the presence of ions. In water, ions set the conditions for how other dissolved particles interact. Ions are also directly involved in chemical reactions affecting the climate such as ozone depletion. READ MORE

  7. 5. Preclinical X-ray imaging beyond attenuation contrast

    Author : Kian Shaker; Hans Hertz; Anna Burvall; Bert Müller; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysik; Physics; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Abstract : Medical imaging is a cornerstone of modern clinical practice. Here, X-ray imaging is the given choice for rapid morphological imaging with excellent spatial resolution, albeit with sensitivity often insufficient for resolving subtle pathological changes to soft tissues. READ MORE
