1. Pathogen-host interactions at the surface of Streptococcus pyogenes
Sammanfattning : The bacterial surface can be thought of as the interface where pathogenic bacteria encounter the human host. Interactions between bacterial surface proteins and human proteins are important determinants of the eventual outcome of infection. LÄS MER
2. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry
Sammanfattning : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. LÄS MER
3. The digestive machinery of a human gut bacterium : Structural enzymology of galactomannan utilisation
Sammanfattning : Human gut bacteria utilise different types of polysaccharides present in our diet. One of these polysaccharides is galactomannan. Many organisms in the phylum Bacteroidetes have gene clusters encoding for all proteins required for hydrolysis, binding and transport of one type of polysaccharide, called polysaccharide utilisation loci (PULs).

4. Properties of Protein and Polymer Systems
Sammanfattning : Interactions of proteins with other proteins, with polymers and with surfaces are of great practical importance within for instance protein purification, drug delivery, and food technology. The aim of this work is to increase the understanding of protein-protein, protein-polyelectrolyte, and protein-surface interactions, particularly concerning the role of electrostatic interactions in these systems.

5. Modeling Quantum Cascade Lasers : The Challenge of Infra-Red Devices
Sammanfattning : We live in a time of rapid scientific and technological advancement. People liv- ing 100 years ago could never dream of inventions like those having completely changed our way of life, and our perception of the world; computers, mobile phones, the Internet, space travel, unraveling the mysteries of the early universe and distant galaxies, and our insight into the microscopic world of quantum phe- nomena.
