1. 1. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Anton Rolseth; [2023]
   Keywords : Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

   Abstract : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. READ MORE

3. 2. Can Dwarf Galaxies Tell Us How the Milky Way Formed?

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Þóra Karlsdóttir; [2023]
   Keywords : Dwarf Galaxy; Milky Way; Physics and Astronomy;

   Abstract : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations.

4. 3. Recurring Slope Lineae on the Northern Hemisphere of Mars: an investigation into the new candidate sites

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Andreas Eriksson; [2021-04-06]
   Keywords : Recurring Slope Lineae; RSL; Mars; HiRISE; Candidate sites; GIS; Northern hemisphere;

   Abstract : Recurring Slope Lineae (RSL), are dark markings found on slopes with a steepness of 25°- 45°. Their width is between 0.5-5 m but they can become hundreds of meters long. They grow incrementally during warm seasons; fade during cold seasons and appear again the following Mars year. READ MORE

5. 4. Study of CO Emission in Nine Hot Dust-Obscured Galaxies at z ∼3

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Timothy Faerber; [2021]
   Keywords : Galaxies; high-z; AGN; starburst; quasar; evolution; cosmology;

   Abstract : Massive galaxies evolve through different phases including starburst-dominated and active galactic nuclei (AGN)-dominated phases. These phases are predicted to be prevalent at earlier times (z ∼ 2 − 3). READ MORE

6. 5. The Effect of Temperature and Fungal:Bacterial Ratio on Kombucha Culture Fermentation

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)
