3. 2. Adapting the bundle of capillary tubes model (BCTM) for vertical soil solute transport modelling

   University essay from Lunds universitet/Miljövetenskaplig utbildning

   Author : Martin Larsson; [2019]
   Keywords : soil solute vertical transport modelling vadose; Earth and Environmental Sciences;

   Abstract : This study explores an approach for adapting the bundle of capillary tubes soil model for vertical soil solute transport modelling. The soil is split into thin layers allowing vertical water flow between capillaries of differing width with concomitant advective flow of solutes. Diffusion is included to improve realism. READ MORE

4. 3. Groundwater flow paths in fractured crystalline bedrock : Electromagnetic VLF measurements and modelling of a groundwater basin in Svanberga, Sweden

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Rasmus Thunell; [2018]
   Keywords : Groundwater; modelling; geophysics; comsol; VLF;

   Abstract : Sweden is a country with a relatively high number of private wells, where about 1.2 million inhabitants in permanent housing and an equal amount in summer housing relies on private wells as their drinking water supply. At the same time the market for drinking water treatment products is unregulated regarding quality and requirements are needed. READ MORE

5. 4. Evaluation of stimulated reductivedechlorination in situ of chlorinatedsolvents at a site in Huddinge : using principal component analysis, partialleast square regression and degradation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Karin Ljungberg; [2018]
   Keywords : Reductive dechlorination; DNAPL; stimulated bioremediation; chlorinated solvents; Reduktiv deklorering; DNAPLS; stimulerad biologisk behandling; klorerade lösningsmedel;

   Abstract : The method of using stimulated reductive dechlorination when remediating sites contaminated with chlorinated solvents is not unusual, but not many studies have been done on the overall process outside of a controlled environment. In order to investigate the process, principal component analysis (PCA) and partial least square (PLS) regression was used to identify the most important parameters for the degradation of the chlorinated solvents.

6. 5. Evaluation of Distribution Function Models for ICRH-induced Impurity Transport in Tokamaks

   University essay from KTH/Skolan för elektro- och systemteknik (EES)

   Author : Håkon Sandven; [2016]
   Keywords : ;

   Abstract : Fusion power is the utilization of the energy released in nuclear fusion reactions. It has the potential to become an energy source which is more sustainable, safer and cleaner than the primary energy sources today. The fundamental problem for fusion power is energy confinement.
