1. Enumerative combinatorics related to partition shapes
Sammanfattning : This thesis deals with enumerative combinatorics applied to three different objects related to partition shapes, namely tableaux, restricted words, and Bruhat intervals. The main scientific contributions are the following. LÄS MER
2. Nuclear fission and fusion in a random-walk model
Sammanfattning : This dissertation deals with theoretical descriptions of nuclear fission and synthesis of superheavy elements via fusion. The associated shape evolutions are treated using a random-walk approach where both the potential energy and the nuclear level density influence the dynamics. LÄS MER
3. Asexual embryogenesis in plants
Sammanfattning : The capacity of somatic cells and pollen grains or microspores to undergo embryogenesis is an important property used in improvement and regeneration of plants. Furthermore, somatic embryogenesis as well as pollen embryogenesis show many similarities with zygotic embryogenesis and are, thus, good model systems. LÄS MER
4. Moisture-induced distortion in timber structures - examples based on partition walls
Sammanfattning : The shape of timber changes due to variations in moisture content (MC). In Scandinavia, producers normally dry timber to an MC of 18%. However, after the studs are built into the wall structure, for example, they may become distorted as a result of further drying in the structure. The final MC in a heated building in Scandinavia is about 8%. LÄS MER
5. Nanosized Bilayer Disks as Model Membranes for Interaction Studies
Sammanfattning : PEG-lipid stabilized bilayer disks have been found in lipid mixtures containing polyethylene glycol (PEG)-lipids where the combination of a high bending rigidity and low PEG-lipid/lipid miscibility favours disk formation. The disks are planar and circular in shape and their long-term stability is excellent. LÄS MER
