1. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets
Abstract : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. READ MORE

2. A Solution Exchange Platform for Exposure of Cells to Chemical Waves
Abstract : This thesis presents the development, characterization and suggested applications of a platform for controlling the chemical environment around a cell or a cell constituent. The platform is unique in its capability to combine rapid solution switching with precise timing and access to a manifold of solution environments. READ MORE

3. Techniques to manipulate the environment around and inside single cells
Abstract : Several methods for extending the functionality of a commercially available microfluidic system have been developed to allow for the manipulation of the extracellular and intracellular environments. The microfluidic system generates a chemically patterned laminar flow in an open volume. READ MORE

4. Character and Function of Anammox Bacteria under Environmental Stress
Abstract : During the last few decades observations of novel processes involved in nitrogen transformations have fundamentally challenged the view of pathways and controlling mechanisms during local and global nitrogen cycling. Anaerobic ammonium oxidation (anammox) constitutes one of these new pathways where autotrophic bacteria oxidize ammonium by nitrite to dinitrogen gas under anaerobic conditions. READ MORE

5. Glycolytic oscillations in individual yeast cells
Abstract : Oscillations in the concentration of yeast glycolytic intermediates have been intensively studied since the 1950s, but these studies have so far been limited to observations of average oscillatory behavior in synchronized cultures. Hence, it has remained unknown whether the onset of oscillations is a collective property of the population which requires a high cell density, or if individual cells can oscillate also in isolation.
