1. 16. Towards a sustainable substitute for Acrylonitrile Butadiene Styrene (ABS) in automotive industry

   University essay from KTH/Fiber- och polymerteknologi

   Author : Amalia Christoula; [2023]
   Keywords : Polylactide PLA ; Biobased; Life Cycle Analysis LCA ; Impact modifiers; Lignocellulose nanofibers LCNF; Polylaktid PLA ; Biobaserad; Livscykelanalys LCA ; Slagtålighet; Nanofibrer av lignocellulosa LCNF ;

   Abstract : Syftet med detta examensarbete var att utveckla ett hållbart ersättningsmaterial till akrylnitrilbutadienstyren plast (ABS), genom att applicera principerna för grön kemi och teknik. ABS är en icke-nedbrytbar plast som till exempel används i slagtåliga produkter för hyttinteriörer. READ MORE

3. 17. Towards a new aesthetics of care : a critical reading of Nassauer’s cues to care

   University essay from SLU/Dept. of Urban and Rural Development

   Author : Jack Richold; [2023]
   Keywords : cues to care; Joan Nassauer; Timothy Morton; strange stranger; sublime; scenic; broken windows; ecological function; aesthetics of care; design through maintenance;

   Abstract : Joan Nassauer’s concept of cues to care has been influential within landscape design since her seminal essay Messy Ecosystems, Orderly Frames was published in 1995 and her research is often used to justify the need for marking landscapes as owned, although there have been critical voices too. The enduring popularity of cues to care as a design method is due to how open it is to interpretation, and this thesis examines various landscape interventions that can be classed as cues to care, both explicitly and implicitly.

4. 18. Analysis of energy efficient heat and lighting systems in a subarctic greenhouse

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : William Sigvardsson; [2023]
   Keywords : Energy efficiency; Sub-arctic greenhouses; Energy measures; Greenhouse climate control; Greenhouse technology; CFD;

   Abstract : This report studies a subarctic greenhouse located in Nikkala, Sweden called Nikkala handelsträdgård. Through a visit to the greenhouse coupled with the creation of two simulation models this study investigates the differences in energy demand with water-carried and air-carried heating systems, high pressure sodium lights and Light emitting diode lights and insulation in parts of the greenhouse without a active cultivation.

5. 19. Simulation of the Filling of Epoxy in Resin Impregnated Paper Bushings : Analysis of Temperature Measurements during Filling of Epoxy and the Generation of New Filling Recipes to Avoid Cavities in the RIP Bushing

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Hanna Damsgaard Falck; [2023]
   Keywords : Porous media; COMSOL Multiphysicis; Darcy s Law; Richard s Equation; Resin Impregnated Paper Bushings; RIP Bushings; Bushings; Transformers; Epoxy; Simulation;

   Abstract : The goal of the project was to create a model in COMSOL Multiphysics that can simulate thefilling of resin (epoxy) in Resin Impregnated Paper (RIP) bushings. Using the model new fillingrecipes that avoid problematic double-fronts and thereby avoid the creation of cavities in thebushings should be designed. READ MORE

6. 20. Lithium-ion Behaviour in Hard Carbon Anodes: Insights from 7Li NMR Spectroscopy

   University essay from KTH/Kemi

   Author : Adina Landström; [2023]
   Keywords : NMR spectroscopy; hard carbon; anode; lithium-ion battery; spin relaxation; NMR-spektroskopi; hårt kol; anod; litiumjonbatteri; spinnrelaxation;

   Abstract : Litiumjonbatterier (LIB) är viktiga komponenter i dagens teknologi och används för att driva en mängd olika elektroniska system, allt från datorer och mobiltelefoner till bilar och flygplan. Eftersom efterfrågan på effektiv energilagring fortsätter att växa finns ett fortsatt behov för forskning och utveckling inom området. READ MORE
