1. 1. Tracing Tempera through Time-of-Flight Secondary Ion Mass Spectrometry Analysing samples from four icons from the Nationalmuseum collection

   Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Nina Olivier; [2024-01-30]
   Nyckelord :Icons; tempera; emulsions; analysis methods; ToF-SIMS;

   Sammanfattning : This thesis will analyze samples in form of cross-sections taken from four icons of the Nationalmuseum collection, two Russian, from the 18th and 19th centuries and two Greek, also from the 18th and 19th centuries, using the Time-of-Flight Secondary Ion Mass Technique. The objective is to detect, isolate and, if possible, identify the amino acids and the fatty acids in the protein and lipids used in the tempera, the ground, and the olifa using Time of Flight Secondary Ion Mass Spectrometry.

3. 2. Utvärdering av biotopvårdande åtgärder i Grimåsbäcken. En analys av fysikaliska egenskaper och sammansättning av makroevertebrater.

   Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Författare :Björn Andermo; [2024-01-22]
   Nyckelord :Channelized streams; retention; biotope preservation; macroinvertebrates; bottom substrate; woody debris.;

   Sammanfattning : Many streams have been exposed to extensive anthropogenic impact for the benefit of forestry and agriculture. The effects has mainly been channelization characterized by lowered and straightened channels. This homogeneous morphology leads to decreased ability to retain water as well as lost connection to the floodplain. LÄS MER

5. 4. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Jonatan Uusitalo; [2023-08-17]
   Nyckelord :;

   Sammanfattning : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.
