1. Potassium in the Galactic Bulge - as traced by microlensed dwarf & sub-giant stars
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : During this report the potassium (K) trend in the Galactic Bulge, with respect to metallicity and various α-elements, has been computed and evaluated by a method of line synthesis on the 7698.96 ̊A KI line (7699 KI), where Non-Local-Thermal-Equilibrium (NLTE) effects have been considered.

2. Spår i jorden : en studie av ett extraktionslandskap
Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : Detta examensarbete utforskar torvtäkten som landsakap. Torvindustrin har en långtgående historia i Sverige, och de utdikade torvmossarna utgör några av de största landskapssåren i landet. Under påtryckningar från politik och samhälle har industrin minskat kraftigt, och många torvtäkter hotas nu av nedläggning. LÄS MER
3. Expansions of neutrino oscillation and decay probabilities in matter
Master-uppsats, KTH/FysikSammanfattning : We consider a simple model for invisible neutrino decay as a sub-leading effect in the standard three-flavor neutrino oscillation framework, and use the Cayley–Hamilton formalism to obtain a full set of neutrino oscillation probabilities in matter. These are given as analytical series expansions in the small parameters α ∼ O(λ^2) and s_13 ∼ O(λ), where λ ≡ 0. LÄS MER
4. Non-Diffractive Nuclear Excitations In Angantyr
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : To better understand collectivity in high energy physics, the heavy-ion collision model Angantyr was developed to be included in the event generator Pythia. In this model, proton-proton collision phenomenology is extrapolated to heavy-ion collisions without assuming a thermal plasma for particle production. LÄS MER
5. Neutrino Oscillations and Scalar Non-Standard Interactions at ESSnuSB
Master-uppsats, KTH/FysikSammanfattning : This report consists of two parts. Firstly, an introduction to neutrino oscillations is presented. This includes introducing neutrino mass terms into the standard model, the leptonic mixing matrix, neutrino oscillations in vacuum and neutrino oscillations in matter. LÄS MER
