1. 1. PLASTER CASTS AND CORROSION AN EXPERIMENTAL STUDY ON REMOVAL OF CORROSION PRODUCTS FROM PLASTER CASTS

   University essay from Göteborgs universitet/Institutionen för kulturvård

   Author : Gabriella Zimmerman; [2023-11-07]
   Keywords : plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

   Abstract : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. READ MORE

3. 2. APPLICATION OF IN SITU Rb-Sr DATING AND GEOCHEMICAL INVESTIGATIONS ON A NEW, 1.52-1.56 GA. OLD PEGMATITE FIELD IN THE ARCHIPELAGO OFF GOTHENBURG, IDEFJORDEN TERRANE, WESTERN SWEDEN

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Laszlo Zorc; [2023-08-18]
   Keywords : ;

   Abstract : In this study, Rb-Sr geochronology was used to determine the crystallization/cooling ages of muscovites and biotites from mapped primitive barren and rare element pegmatites in the Stora-Le-Marstrand Formation in the southwestern archipelago of Gothenburg. The results indicate that primitive barrens can be linked to the DG2 deformation event that occurred 1. READ MORE

4. 3. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ivana Pia Saric Söderholm; Erik Readwin; [2023]
   Keywords : Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

   Abstract : 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.

5. 4. A geological investigation on bedrock suitability for mineral carbonation conducted in the south central part of Sweden

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Edvard Pearson; [2023]
   Keywords : Mineral carbonation; geological investigation; Åsensbruk; Falun; Grums; Öje; Skutskär;

   Abstract : Increasing global temperatures due to anthropogenic emissions of greenhouse gases is one of our times most dire and urgent challenges to overcome if we are to achieve a sustainable healthy planet. The primary way of accomplishing this is by reducing the amount of released greenhouse gases. READ MORE

6. 5. Reconstructing Past Climate by Using XRF and Loss of Ignition on Loess from Adventdalen, Svalbard : Rekonstruktion av tidigare klimat genom attanvända XRF analys och antändningsförlust på lössavlagringar från Adventdalen, Svalbard

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Albin Andreasson; Noa Lind; [2023]
   Keywords : Svalbard; loess soil; XRF; weathering; climate change;

   Abstract : By analyzing the texture, composition and chemical composition of loess soils, the reconstruction ofpast climate regimes is enabled, which can improve our understanding of current and future climatechange. Properties such as grain size and composition, mineralogy, organic matter and chemicalcomposition can provide information about which environmental factors were present during thedeposition of the sediment, which can lead to a detailed picture of the climate history of a site.
