6. Animating soils : geoarchaeological approaches to past human-environment relationships in the Arctic
Sammanfattning : In this thesis, soils and sediments have been used as sources of information on past human activity in Arctic environments. The study has combined geoarchaeological methods and techniques with information from historical documents, ethnographic accounts, and archaeological remains to create integrated narratives of human-landscape interactions in the past.

7. Passive sampling of PAHs and some trace organic compounds in occupational and residential air: needs, evaluation and limits
Sammanfattning : Human exposure to elevated levels of polycyclic aromatic hydrocarbons (PAHs) and trace organic compounds (e.g. PCB, OCP, PBDE) can be related to negative health effects. This raises demands of exposure measurements to be performed. LÄS MER
8. Greenhouse gas emission from tropical reservoirs : Spatial and temporal dynamics
Sammanfattning : The emission of methane (CH4) and carbon dioxide (CO2) from reservoirs has been estimated to make up for about 1.3% of the global anthropogenic greenhouse gas emission. The impoundment of a river leads to the accumulation of sediment that is brought in from inflowing rivers, and the sediment organic matter is degraded to CH4 and CO2. LÄS MER
9. The Sampling Pattern Cube : A Framework for Representation and Evaluation of Plenoptic Capturing Systems
Sammanfattning : Digital cameras have already entered our everyday life. Rapid technological advances have made it easier and cheaper to develop new cameras with unconventional structures. The plenoptic camera is one of the new devices which can capture the light information which is then able to be processed for applications such as focus adjustments. LÄS MER
10. Optimizing sampling of important events in complex biomolecular systems
Sammanfattning : Proteins and DNA are large, complex molecules that carry out biological functions essential to all life. Their successful operation relies on adopting specific structures, stabilized by intra-molecular interactions between atoms. LÄS MER
