1. 21. Evaluation of the LPJ-GUESS crop model under ambient and elevated CO2 concentrations.

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Annika Nitschke; [2022]
   Keywords : LPJ-GUESS; free-air carbon dioxide enrichment experiments; elevated CO2; climate change; wheat yield; Earth and Environmental Sciences;

   Abstract : In the future atmospheric CO2 concentrations might exceed 550 ppm according to the RCP8.5 scenario by mid-century from our current 410 ppm, while our world population is projected to surpass the 9.7 billion threshold within the same time span. This challenge leads to the raising of questions addressing future food security. READ MORE

3. 22. Drivers of decomposition across Sphagnum bog margins

   University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

   Author : Emil Nordström; [2022]
   Keywords : Peatlands; tea bag index; edge effects; carbon storage; carbon sequestration; waterlogging; Torvmark; kanteffekter; kollagring; koldioxidbindning;

   Abstract : Peatlands provide multiple ecosystem services, including extensive carbon sequestration and storage, yet many peatlands have been degraded or destroyed. Peatlands carbon storage capacity is connected to inherently low decomposition rates, causing the build-up of organic matter.

4. 23. Enhancement of translucence in fiber-based packaging materials

   University essay from KTH/Fiber- och polymerteknologi

   Author : Saila Tallinen; [2022]
   Keywords : Paper; translucent; fiber-based packages; impregnation; cellulose; papper; genomskinlighet; fiberbaserade förpackningsmaterial; impregnering; cellulosa;

   Abstract : The utilization of fiber-based packages has started to take more place at the packaging sector but is still restricted by a lack of transparency. Today this challenge is tried to be solved by paying more attention on the characteristics of nanofibers and their possibilities. READ MORE

5. 24. Spinning Correlators at Finite Temperature

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Oscar Arandes Tejerina; [2022]
   Keywords : Conformal Field Theory; Finite Temperature; Thermal Conformal Blocks; AdS CFT; Mean Field Theory;

   Abstract : This master thesis is framed in the striking correspondence between gravity theories in Anti-de Sitter spacetime (AdS) and Conformal Field Theories (CFT). This is usually known as AdS/CFT duality and relates gravity theories in the bulk with CFTs that live in their conformal boundary. READ MORE

6. 25. Evaluating forest wildfire effect on tree increment patterns for boreonemoral forests in Sweden: A pilot study using remote sensing

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Joanna Eaton; [2022]
   Keywords : Physical Geography and Ecosystem analysis; Remote sensing; Sentinel-2A; Forest wildfires; dNBR; NDVI; dNDVI; Dendrochronology; Atmospheric science and biogeochemical cycles; Earth and Environmental Sciences;

   Abstract : The release of anthropogenic greenhouse gases (GHGs) has substantially increased the global mean surface air temperature. Increases in global mean surface air temperature will lead to warmer and drier conditions, promoting more frequent, long-lasting, intense forest wildfires. READ MORE
