1. 11. Optimization of Gammasphere Data Following the Nuclear Reaction 36Ar + 24Mg → 60Zn∗

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Författare :Paul Böhm; [2023]
   Nyckelord :re-calibration; Gammasphere; 54Fe; Physics and Astronomy;

   Sammanfattning : The experiment at Argonne National Laboratory aimed to study the fusion-evaporation reaction following the collision of a high-energy particle beam of 36Ar with a stationary target of 24Mg. This paper outlines the creation and implementation of an automated re-calibration procedure for the high-purity Germanium detectors comprising the Gammasphere array used for γ-ray spectroscopy in this experiment.

3. 12. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

   Master-uppsats, Lunds universitet/Materialteknik

   Författare :Johan Ranstad; [2023]
   Nyckelord :Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

   Sammanfattning : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. LÄS MER

4. 13. The impact of addition of force control agent in adhesive mixtures : Effect of magnesium stearates on flowability and aerosolization properties

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaceutisk biovetenskap

   Författare :Moa Erlandsson; [2023]
   Nyckelord :;

   Sammanfattning : When drugs need to be delivered to the respiratory system dry powder inhalers (DPIs) are often used. The powders in DPIs often consists of a micronized active pharmaceutical ingredient (API) that is adhered to a larger carrier particle forming an adhesive mixture. LÄS MER

5. 14. Concept investigation into Metal Plasma Source for High Powered Space Applications

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Ludvig Borg; [2023]
   Nyckelord :High-powered; Electric Propulsion; Vacuum Arc Thruster; VASIMR; Metal Plasma; Magnetohydrodynamics; COMSOL Multiphysics;

   Sammanfattning : This thesis explores the potential of utilizing metal-based plasma sources as a sustainable solution for high-powered electric propulsion and its implications for future interplanetary travel. Focusing on the Vacuum Arc Thruster and the Variable Specific Impulse Magnetoplasma Rocket engine, the study encompasses numerical simulations, analytical comparisons, and performance analyses to assess the feasibility of metal plasma fuels in space missions.
