1. Microbially mediated formation of birnessite-type manganese oxides and subsequent incorporation of rare earth elements, Ytterby mine, Sweden
Sammanfattning : Microbes exert extensive control on redox element cycles. They participate directly orindirectly in the concentration and fractionation of elements by influencing the partitioningbetween soluble and insoluble species. LÄS MER
2. Recruitment ecology and fungal interactions in mycoheterotrophic Ericaceae
Sammanfattning : There are generally two contrasting alternatives to what limits recruitment in plants, namely the availability of seeds (seed limitation) or the quality or quantity of suitable sites (microsite limitation). Dust seeds, the smallest existing seeds, lack or have minimal nutrient reserves. LÄS MER
3. Contested Landscapes/Contested Heritage : history and heritage in Sweden and their archaeological implications concerning the interpretation of the Norrlandian past
Sammanfattning : This case study explores how geo-political power structures influence and/or determine the conception, acceptance and maintenance of what is considered to be valid archaeological knowledge. The nature of this contingency is exemplified through an examination of how the prehistory of Norrland, a region traditionally considered and portrayed as peripheral vis-à-vis the centre-South, was interpreted and presented by Swedish archaeologists during the 20th century.

4. Towards Enabling Exploration of Planetary Subterranean Environments using Unmanned Aerial Vehicles
Sammanfattning : This thesis presents a novel navigation framework established to enable the exploration of planetary subterranean areas with Unmanned Aerial Vehicles (UAVs). The key contributions of this thesis work form a robot-safe rapid navigation framework that utilizes a novel bifurcating frontier-based exploration approach. LÄS MER
5. Boplatsvallen som bostad i Norrbottens kustland 5000 till 2000 före vår tideräkning : en studie av kontinuitet och förändring
Sammanfattning : This thesis focuses on the use of the semi-subterranean house on the coast of Norrbotten during the period 5000–2000 BC. The term semi-subterranean house (in Swedish boplatsvall) became a new category of prehistoric remains in Norrbotten during the 1980s. LÄS MER
