1. Energy relavant materials: Investigations based on first principles
Sammanfattning : Energy production, storage and efficient usage are all crucial factors for environmentally sound and sustainable future technologies. One important question concerns the refrigeration industry, where the energy efficiency of the presently used technologies is at best 40% of the theoretical Carnot limit. LÄS MER
2. Multi-Agent Mission Planning and Execution for Small Autonomous Underwater Vehicles
Sammanfattning : Our planet is mostly covered in water, most of it still unexplored.In order to understand our environment better, oceanographers have been mapping and monitoring these waters using ship-mounted sensors and wired vehicles with limited range compared to the vastness of the oceans.

3. To reduce a ribonucleotide – Radical solutions in enzymology in form and function
Sammanfattning : It has been more than 50 years since the enzyme system ribonucleotide reductase (RNR), catalysing the reduction of ribonucleotides to deoxyribonucleotides, was first discovered. RNR was also the first time that radical chemistry was revealed in an enzyme. LÄS MER
4. Colonisation and PAH degradation by wood-rotting fungi in contaminated soil
Sammanfattning : Bioremediation of soils is considered a low-cost alternative to other remediation techniques. Its ability to remove a number of different pollutants has been demonstrated, relying mainly on the activities of indigenous soil bacteria. LÄS MER
5. Samhällets styrning av fastighetsindelningen : Dåtid, nutid och framtid
Sammanfattning : Markens indelning i fastigheter utgör en grundläggande beståndsdel i samhällsbyggandet. De krav som ställs på fastighetsindelningen får konsekvenser för vilka fastigheter som får bildas, registreras och ägas vilket i sin tur påverkar samhällsutvecklingen i ett bredare perspektiv genom att ange förutsättningarna för var människor kan bo och bedriva olika verksamheter.
