1. 1. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Linnéa Eriksson; [2023-04-20]
   Keywords : soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

   Abstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

3. 2. Future Imaginaries of Negative Emission Technologies and Folklore Myths in Icelandic Basalt: Provisional Order Emerges from the Possible Magma in the Age of ‘Hauntology’ and Broken Time

   University essay from Lunds universitet/Kulturgeografi och ekonomisk geografi; Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/Humanekologi

   Author : Rikke Jespersen; [2023]
   Keywords : NETs; Desire; Green Capitalism; Imaginaries; Storytelling; Pluriverse; Social Sciences;

   Abstract : Why do we in the Western part of world today tend to believe in technology’s mythical promises rather than in folklore myths? Imaginaries of the future influence political subjects’ actions in the present and play a key role in composing the trajectory towards the future. I have critically applied this notion to the implementation of negative emission technologies in the climate-neutrality strategy. READ MORE

4. 3. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Nsioh Elvis Nkioh; [2022]
   Keywords : geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

   Abstract : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE

5. 4. Biochar as a carbon dioxide removal solution : An assessment of carbon stability and carbon dioxide removal potential in Sweden

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Alessandro Corbo; [2020]
   Keywords : Climate change mitigation; biomass; pyrolysis; soil;

   Abstract : Biochar is increasingly gaining momentum in the context of climate change mitigation and its production in Sweden could potentially become a large-scale system. Carbon stability in biochar is a crucial factor to assess its the carbon sequestration potential. READ MORE

6. 5. Spatial Variability in Greenhouse Gas Production in Sediments of a Tropical Reservoir

   University essay from Uppsala universitet/Limnologi

   Author : Stina K. Björkman; [2015]
   Keywords : CH4 production; C N-ratio; water content; carbon mineralisation; tropical reservoir; greenhouse gas emission;

   Abstract : The objective was to study the spatial variability of organic matter degradation in the sediments of a tropical reservoir to answer the hypothesis that degradation is significantly higher in river inflow areas than in other parts of the reservoir. Sediment cores were collected from twelve sites in the nutrient poor drinking water reservoir Chapéu d’Uvas in Minas Gerais, Brazil. READ MORE
