1. 1. Measuring copper abundances in the Galactic Bulge

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

   Author : Nikolei Höglinger; [2024]
   Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

   Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

4. 3. Mullet - a multifunctional workingspace

   University essay from Lunds universitet/Industridesign

   Author : Malin Johansson; [2023]
   Keywords : Arts and Architecture; Technology and Engineering;

   Abstract : In today’s design environment we are constantly in movement. Whether it is making models or tracing a sketch, we need to go to specific stations intended for the task. It is not just time consuming but also a problem. Stress might occur due to the fact that you never know whether the light table or the cutting mat will be preoccupied. READ MORE

5. 4. Mitigation of supply chain uncertainties caused by material shortage : A case study with Loccioni

   University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

   Author : Juliane Wloch; [2023]
   Keywords : Supply chain risk management; supply disruption management; semiconductor shortage; Small- and Medium-sized Enterprises;

   Abstract : The ongoing semiconductor shortage impacts organizations throughout the supply chain operationally and financially. Limited material for a sudden increase in demand during the Covid-19 pandemic led to a heightened supplier power and result in the prioritization of customers. READ MORE

6. 5. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Vikramjeet Das; [2023]
   Keywords : rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

   Abstract : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. READ MORE
