1. Nya metoder för fernissaborttagning – En komparativ studie
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : In recent years, new varnish removal methods have emerged in conservation, with two notable approaches: the tissue-gel composite method, involving gel-coated tissue material pressed onto varnished surfaces for simultaneous dissolution and binding, and the use of Evolon® CR textile saturated with solvent. Evolon® CR offers an alternative to gels and tissue-gel composites, aiming to eliminate residue from gel thickening agents and the need for mechanical cleaning, while enabling the use of non-polar solvents in a bound form.

2. FÖRUNDERSÖKNING AV EN EGYPTISK POLYKROM KISTA Dokumentation, tillståndsbeskrivning och analys
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : On ancient Egyptian polychrome art and mainly on coffins, it was normal practice to apply a thick ground and gesso before painting the wood. Sometimes varnish was also applied. Due to fluctuating levels of relative humidity and temperature, the wood swells and shrinks, causing the layers on top of the wood to become damaged. LÄS MER
3. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

4. Vem sköt på Bomarsund i augusti 1854? : pXRF-analys av blykulor och dess anslag kopplade till rörelser i landskapet under slaget om Bomarsund 1854
Master-uppsats, Stockholms universitet/Institutionen för arkeologi och antikens kulturSammanfattning : The Battle of Bomarsund was fought by three nations, all of which left behind lead residues at the site. These residues consist of both lead bullets from rifles, as well as impact marks from bullets fired at the fort. LÄS MER
5. Historical mining of Fe-Ca ore in Garpenberg, Sweden. : A study based on lake sediment geochemistry from Finnhytte-dammsjön.
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : It is well established that mining and metallurgy on a larger scale in Sweden originated in Bergslagen. The historical mining district Garpenberg in Bergslagen presently show the oldest signs of mining in Sweden (2300 BP) based on a study of a lake sediment profile from Gruvsjön. LÄS MER
