1. 21. Designing Mesoporous Test Sticks for Measuring PFAS Concentrations in Water

   Master-uppsats, Linköpings universitet/Nanostrukturerade material

   Författare :Amanda Hillås; [2022]
   Nyckelord :Mesoporous material; PFAS; PFOA; PFOS; Rose Bengal; adsorption;

   Sammanfattning : Water contamination through substances called per- and polyfluoroalkyl substances (PFAS) is a worldwide problem. Being able to measure the concentrations of PFAS in water is a first step towards beating this contamination. One alternative is to use a field test kit instead of extensive lab equipment to monitor the contaminated areas. LÄS MER

3. 22. ”DET SKULLE VARA LÄTTARE IFALL DET INTE VAR EN GRUVA” : En kvalitativ fallstudie omimplementering av en uppkopplad filterindikator i gruvindustrin.

   Sammanfattning : The extraction of metal and other natural resources has historically been and is still today an important part of Swedish society and its development. To keep pace with demand and at the sametime increase security, more and more digital technology has been implemented into the miningindustry. LÄS MER

4. 23. Bearbetningsmetoders påverkan på markorganismers aktivitet i jorden : i perenna odlingar samt i odlingssystem med mellangrödor

   Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

   Författare :Jenny Olofsson; [2021]
   Nyckelord :markorganismer; respiration; organiskt material; odlingsmetoder; biologiska processer; kemiska processer och fysikaliska processer; perenna odlingssystem; mellangrödor; klimatförändringar; microbial activity; respiration; organic matter; soil tillage methods; biological processes; chemical processes and physical processes; perennial crops; conservation agriculture; intermediate crops; climate change;

   Sammanfattning : Klimatförändringarna, som både påverkat och påverkar vår planet, kräver att mänskliga aktiviteter förändras till mer resurssnåla och systemeffektiva processer. I dessa processer bör markens bördighet vara det centrala, eftersom en bördig mark kan generera stabila skördar och bidra till en långsiktigt hållbar matförsörjning. LÄS MER

5. 24. LES modelling of spray combustion

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Arvid Åkerblom; [2021]
   Nyckelord :Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

   Sammanfattning : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.
