1. Measuring copper abundances in the Galactic Bulge
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

2. Copper abundances of F and G dwarf stars in the Milky Way
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : An investigation has been done in order increase the understanding of the origin and chemical evolution of copper in the Milky Way stellar disks. This is interesting to know as it plays a part of the Galaxy puzzle, so we become more able to map how and why galaxies look like they do. LÄS MER
3. The presence of REE in titanite, garnet and epidote from the Aitik mine tailings
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : The aim of this thesis is to investigate the rare earth element (REE) distribution within titanite, garnet and epidote from the Aitik mine tailings, the waste material of a large porphyry-copper deposit mined in northern Sweden. The mine is an open pit operation with a low grade – high tonnage ore that generates roughly 36 Mt of tailings annually. LÄS MER
4. Mobility, habitat selection and population connectivity of Lycaena helle in central Sweden : implications for conservation
Master-uppsats, SLU/Dept. of EcologySammanfattning : Lycaena helle is an endangered butterfly that is mainly threatened by habitat degradation and fragmentation. For all species with a fragmented distribution, knowledge about mobility, habitat requirements and connectivity is key to developing successful conservation strategies. LÄS MER
5. Nitrifierande mikrobiella samhällen som indikatorer för förorenad jord : Jämförelse av den genetiska och funktionella potentialen
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : I Sverige finns det ungefär 25 000 riskklassade förorenade områden samt ännu fler områden som potentiellt är förorenade. Naturvårdsverket har tagit fram generella riktvärden för olika förorenade ämnen. LÄS MER
