1. ## 1. Diffusion MRI of Brain Tissue: Importance of Axonal Trajectory

Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

Sammanfattning : Obtaining microstructural information non-invasively on brain tissue remains a challenge. Diffusion magnetic resonance imaging (dMRI) is an imaging method that can provide such information. That includes geometrical considerations of nerve cells projections, axons, that are present in the white matter of the human brain. LÄS MER

2. ## 2. Strange Hadron Production as a Function of Multiplicity and Transverse Spherocity in proton-proton Collisions at $\sqrt{s}=13$~TeV

Master-uppsats, Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

Nyckelord :Physics and Astronomy;

Sammanfattning : This thesis presents the study of the K$^{0}_{s}$, $\Lambda$, and $\bar{\Lambda}$ production in pp collisions at $\sqrt{s}=13$~TeV recorded by the ALICE experiment at the LHC. The K$^{0}_{s}$, $\Lambda$, and $\bar{\Lambda}$ particles are reconstructed in the transverse momentum ($p_{\mathrm{T}}$) range of \$1.0-12. LÄS MER

3. ## 3. Copper abundances of F and G dwarf stars in the Milky Way

Kandidat-uppsats, Lunds universitet/Astronomi

Sammanfattning : An investigation has been done in order increase the understanding of the origin and chemical evolution of copper in the Milky Way stellar disks. This is interesting to know as it plays a part of the Galaxy puzzle, so we become more able to map how and why galaxies look like they do. LÄS MER

4. ## 4. The impact of turbulence on supernovae shockwaves

Kandidat-uppsats, Lunds universitet/Astronomi

Sammanfattning : The momentum and energy injection from supernovae is one of the main feedback modes, and is therefore key to the understanding of galaxy evolution and star formation. However, due to low resolution, large scale galaxy simulations often have issues with accurately modelling supernovae, and therefore rely on sub-grid models. LÄS MER

5. ## 5. Electrons from heavy- flavor semileptonic decays in proton-proton collisions at √s=13 TeV measured with the ALICE detector at the LHC

Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikelfysik

Sammanfattning : Heavy-flavor hadrons, containing charm and bottom quarks, serve as a tool available for the characterization of the hot and dense strongly interacting Quark Gluon Plasma state of matter, produced in heavy-ion collisions. As a benchmark for heavy-ion collision measurements, proton-proton collisions are also studied. LÄS MER
