1. In vivo analysis of amino acid permease folding in yeast
Sammanfattning : Plasma membrane (PM) proteins are critical for cells to respond to environmental cues, such as the availability of nutrients. The yeast Saccharomyces cerevisiae is able to sense extracellular amino acids using the SPS sensing system. LÄS MER
2. Simulation of additive manufacturing using a mechanism based plasticity model
Sammanfattning : This thesis presents finite element (FE) simulations of additive manufacturing (AM) and physically based material modeling of alloy 625 and alloy 718. In recent years, there has been an increasing interest in AM and there has been a dramatic increase in publications in the field. LÄS MER
3. Dendrimers and dendronized polymers : synthesis and characterization
Sammanfattning : The goal of this work was to synthesize complex macromolecular architectures such as dendrimers and dendronized polymers, and evaluate the effect from the dendrons on the optical and material properties. The work presented in this doctoral thesis, Dendrimers and Dendronized Polymers - Synthesis and Characterization, is divided into one minor and one major part. LÄS MER
4. Enzymatic metal-chelation by porphyrins
Sammanfattning : This thesis deals with the structure and function of two different enzymes, ferrochelatase and magnesium chelatase, that catalyse similar reactions. When this work started, a three-dimensional model of ferrochelatase existed. Much was known about the enzyme, but some details remained unclear. LÄS MER
5. On the effects of surface roughness in lubrication
Sammanfattning : Tribology is a multidisciplinary field defined as the science and technology of interacting surfaces in relative motion, and embraces the study of friction, wear and lubrication. A typical tribological application is the rolling element bearing. LÄS MER
