1. Paper planes : labour migration, integration policy and the state
Abstract : This dissertation collects four peer-reviewed articles that are published in academic journals. Two of the articles are about the multi-level governance of integration polices, and two study the effects of labour migration policies. READ MORE

2. Lactic acid production: extractive fermentation in aqueous two-phase systems
Abstract : There is an increased interest in the microbial production of lactic acid as a raw material for the synthesis of lactic acid polymers as biodegradable plastics. However, two factors limit the economical competitiveness of lactic acid production by microorganisms: lactic acid inhibition, which decreases both fermentation rate and the maximum lactic acid concentration, and the efficiency in the recovery of lactic acid.

3. Space in Proof Complexity
Abstract : ropositional proof complexity is the study of the resources that are needed to prove formulas in propositional logic. In this thesis we are concerned with the size and space of proofs, and in particular with the latter.Different approaches to reasoning are captured by corresponding proof systems. READ MORE

4. Localization effects in ternary nitride semiconductors
Abstract : InGaN based blue and near-ultraviolet light emitting diodes and laser diodes have been successfully commercialized for many applications such as general lighting, display backlighting and high density optical storage devices. Despite having a comparably high defect density, these devices are known for their efficient operation, which is attributed to localization in potential fluctuations preventing carriers from reaching the centers of nonradiative recombination.

5. On multilayered system dynamics and waves in anisotropic poroelastic media
Abstract : The mechanical and acoustic anisotropy of media is a governing factor in the behaviour of multilayered systems including such media. The understanding of the mechanisms conditioning the dynamic behaviour of multilayered systems is of paramount importance. READ MORE
