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. Optimization of hot strip drawing test methodology for hot forming of aluminium alloys

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

   Author : Rabia Arshad; [2022]
   Keywords : Hot forming of aluminium; friction; high temperature lubrication; strip draw; wear.;

   Abstract : The development of lightweight design for automotive applications has lasted for many years and is still increasing. Vehicles with light structures use less fuel, emit less CO2, and are better for the environment. READ MORE

4. 3. Projections for charm balance functions in heavy-ion collisions

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Tilde Bonnevier Wallstedt; [2022]
   Keywords : Heavy-ion physics; quark-gluon plasma; QGP; balance function; charm quark; Physics and Astronomy;

   Abstract : In this thesis, pp collisions were simulated using PYTHIA. D+ D- and D0 D0bar balance functions were created in order to contribute with a reference point for future balance functions measured in real data from Pb-Pb collisions. READ MORE

5. 4. Improving the Efficiency of Thermal Energy Usage in Residential Buildings by Heat Recovery from Wastewater

   University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Author : Pranjal Jain; Khaled Alturkmani; [2021]
   Keywords : Wastewater; Heat Exchangers; Heat Pumps; Biofilms;

   Abstract : This study aims to rationalize the consumption of thermal energy in residential buildings by recovering heat from wastewater inside the building before entering the central sewage network outside the building, by conducting an analytical study for a residential tower in Syria to find out the coverage percentage of the heat energy recovered from wastewater for the heating and domestic hot water loads needed for the tower, and calculating the percentage of reduction in carbon dioxide (CO2) gases. It is a simple technology as the thermal recovery system consists of three main components, which are in order: a wastewater tank, heat exchangers, and a heat pump. READ MORE

6. 5. 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
