1. Chloride profiling in marine concrete - methods and tools for sampling
Abstract : This project focuses on how to determine the chloride content in concrete structures exposed to marine environment in an accurate way. When analyzing dust from dry drilling in concrete, it is very often a fact that the chloride profiles show extensive variations even if the sampling has been performed within a very concentrated area with the sampling points close to each other.

2. Animating soils : geoarchaeological approaches to past human-environment relationships in the Arctic
Abstract : 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 The study has combined geoarchaeological methods and techniques with information from historical documents, ethnographic accounts, and archaeological remains to create integrated narratives of human-landscape interactions in the past.

4. Measuring occupational dust exposure with a passive sampler
Abstract : Objectives: In a working environment it is important to measure dust exposure to evaluate possible health issues. Passive sampling could be an alternative to active sampling with pumps when measuring occupational dust exposure. One passive sampler is the University of North Carolina passive aerosol sampler (UNC sampler). READ MORE

5. Sampling from a suction induced mini-erosion in human skin. Methodological studies
Abstract : Dermal interstitial fluid (IF) was extracted serially and painlessly by brief suction for as long as 6 days. The erosion was otherwise kept occluded, Sample volumes exceded those required for measuring a wide range of biological substances. Epidermal regeneration was rapid. READ MORE
