1. 1. Soil carbon relations in Swedish agriculture : A GIS analysis and literature review of soil characteristics at farm level

   University essay from Linköpings universitet/Institutionen för tema

   Author : Christiane Schulze; [2022]
   Keywords : Carbon sequestration; Crop yield; Management practices; Soil organic carbon; Soil organic matter; Sweden; northern Europe;

   Abstract : Carbon storage in agricultural soils is an important measure to mitigate climate change. As the soil management techniques can greatly influence the amount of carbon stored in agricultural soils, the influence of different managements was analyzed in a literature review for northern Europe and Sweden.

3. 2. Occurrence and fate of organic micropollutants (OMPs) in Lake Mälaren

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Anna-Lena Rehrl; [2019]
   Keywords : multi-residue method; UPLC-MS MS; SPE; organic micropollutants; surface water;

   Abstract : The main objective of this study is to investigate the occurrence and fate of organic micropollutants (OMPs) in surface water in Lake Mälaren over one year, including their seasonal variations, correlations between compounds, spatial and vertical distribution. The water samples were enriched with solid phase extraction (SPE) and subsequently analyzed by ultra-high pressure liq-uid chromatography tandem mass spectrometry (UPLC-MS/MS). READ MORE

4. 3. Secrets of the Spearhead : Developing Continuum Mechanical Simulations and Organic Residue Analysis for the Study of Scandinavian Flint Spearhead Functionality

   University essay from Stockholms universitet/Arkeologiska forskningslaboratoriet

   Author : Fredrik Lundström; [2019]
   Keywords : spearhead; lithics; flint; projectile point; functionality; organic residue analysis; continuum mechanical analysis; experimental archaeology;

   Abstract : This thesis is a pilot study, designed to test and develop methods suitable for the study of Scandinavian flint spearhead functionality. The functionality of projectile and lithic point armament has not been studied for almost 30 years in Scandinavia. Meanwhile, methods used to analyse lithic projectiles have developed considerably.

5. 4. Liquefaction of Softwood Bark towards Biochemicals and Biofuels

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

   Author : Emma Nordström; [2018]
   Keywords : Softwood; Bark; Liquefaction; Hytrotropic acid; Lignin; Biofuel; Bio-oil; Spruce; Catalyst; Zeolite;

   Abstract : The energy consumption in the world is increasing at the same time as the fossil fuel resources are limited. This is causing a rising interest in renewable energy sources over the world. To reduce dependency on fossil fuel sources biomass is an excellent alternative. READ MORE

6. 5. Testing Direct Coupling Analysis on HP Model Proteins

   University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Mustafa Kadhim; [2018]
   Keywords : Direct Coupling Analysis HP model proteins; Physics and Astronomy;

   Abstract : Direct coupling analysis (DCA) models correlations in sets of related (homologous) protein sequences using a Potts-like spin model ansatz. From the couplings of the Potts model, derived by inverse statistical mechanics, residue-pair contacts in the 3D structure of the protein are predicted. READ MORE
