21. Comparison of different approaches for modelling the beam-target reactivity in fusion plasmas
Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysikSammanfattning : Fusion research has been an ongoing research endeavour for many decades and it has the potential of providing an important part in the future of energy production. An important part of this process is to understand and control the various heating systems of the reactor where one of the most important systems being the Neutral Beam Injector (NBI) which injects particles at high velocities into the plasma.

22. Use of the JET pedestal database to assess the role of ion temperature and plasma rotation on the discrepancy between ideal peeling-ballooning model and experimental data
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Next-generation and present fusion devices such as the Joint European Torus (JET) aim for plasma operations in H-mode, a plasma regime with high confinement and low loss of energy and fuel that results from a barrier for heat and particle transport at the plasma edge, the pedestal. Due to steep gradients of the density, temperature and pressure profiles, the pedestal experiences instabilities called Edge-localized-modes (ELMs) which lead to large fluxes of heat and particles that might damage machine components.

23. Lipoteichoic acid extraction from plasma : Chromatography techniques utilizing truncated derivates of antimicrobial peptides
Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)Sammanfattning : With increasing incidence rates aligned with poor prognosis; sepsis represents one of the biggest challenges in modern health care. It is a multifactorial syndrome defined as organ dysfunction caused by disturbed systemic response to an infection. LÄS MER
24. Investigation of inductive electric fields in Earth’s magnetotail using Magnetospheric Multiscale (MMS) multipoint measurements
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The mutual interaction between the solar wind and the geomagnetic field generates the magnetosphere. The magnetosphere is characterized by many large-scale perturbations, such as substorms, which are responsible for variations in the magnetic field. LÄS MER
25. Using satellite data to calculate entropy of electrons at collisionless shocks
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The solar wind is a supersonic flow of protons and electrons emitted in all directions from the sun. As the supersonic solar wind encounters Earth’s magnetic field, it creates the Earth’s bow shock, which increases the kinetic entropy of electrons passing through it. LÄS MER
