3. 2. Finite Element Modeling of Installation Effects of Soil-Cement Columns

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

   Author : Anne Holtmeier; [2022]
   Keywords : Deep Mixing; Soil Stabilization; Installation; Finite Element Method; PLAXIS;

   Abstract : Since the 1970's deep mixing columns have been widely used all over the world to improve the performance of soft soil in regard to bearing capacity or deformation behaviour. They are installed by mixing a binding agent, e.g. cement, in situ with the soil. READ MORE

4. 3. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

   University essay from SLU/Dept. of Soil and Environment

   Author : Stéphanie Nyström; [2022]
   Keywords : Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

   Abstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

5. 4. Removal of PFASs and Uranium from Drinking Water Using SorbixTM Anion Exchange Resin : Effects of Sodium Chloride on the Removal Efficiency

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Fawaz Rustum; [2021]
   Keywords : Perfluorinated; polyflourinated; adsorption; fluorotelomer; salt; perfluorerade; polyfluorerade; adsorption; fluorotelomer; salt;

   Abstract : The increasing awareness towards PFAS pollution makes it increasingly important to treat. Many agencies over the globe, including the Swedish Food Agency, are introducing ever so strict control over PFASs in drinking water. READ MORE

6. 5. Erosion Behaviour of Thermal Barrier Coatings

   University essay from Linköpings universitet/Konstruktionsmaterial

   Author : Caroline Wännman; [2021]
   Keywords : erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

   Abstract : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. READ MORE
