1. 1. Development of a guide system for free neutron oscillation searches at the European Spallation Source

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/European Spallation Source ESS AB

   Author : Linnéa Björk; [2023]
   Keywords : ESS; neutrons; dark matter; antimatter; neutron guides; Physics and Astronomy;

   Abstract : In this project, a neutron delivery system for the study of free neutron oscillations at the HIBEAM beamline at the European Spallation Source (ESS) has been developed. The HIBEAM experiment is part of a two-stage program at ESS which will address open questions in physics; specifically the nature of dark matter and the observed asymmetry between matter and antimatter in the Universe.

3. 2. Modelling the Water Table in a Bog

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Tobias Bowley; [2023]
   Keywords : Physics and Astronomy;

   Abstract : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

4. 3. Probing Charm Production with Three-Particle Correlations in pp Collisions

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Author : Kim Haupt; [2023]
   Keywords : pp collisions; charm production; three-particle correlation; Pythia; Physics and Astronomy;

   Abstract : This thesis aims to investigate possible correlations between charm production and baryon production in proton-proton collisions through three-particle correlations. The question attempted to be answered is where, for a given charmed baryon, the balancing anti-charm particle and balancing anti-baryon are located. READ MORE

5. 4. The potential nitrous oxide emissions in a permanent grassland chronosequence

   University essay from SLU/Dept. of Forest Mycology and Plant Pathology

   Author : Sandra Lillsjö Kronblad; [2023]
   Keywords : nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

   Abstract : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.

6. 5. Effekt av olika odlingssystem på markstruktur och avkastning : pargårdsstudie i Skåne

   University essay from SLU/Dept. of Soil and Environment

   Author : Clara Kihlstrand; Linnéa Frisk; [2023]
   Keywords : Markhälsa; reducerad jordbearbetning; ; Conservation Agriculture; plöjning; mellangröda; höstvete; aggregatstabilitet; daggmaskar; pH; dragkraft; infiltration; vattenhalt;

   Abstract : Metoderna att odla jordbruksmark är många. Dessa odlingssystem påverkar markstrukturen och markhälsan på olika vis. Markhälsa är ett begrepp som blir allt viktigare. Under 2023 kommer EU med nya markdirektiv som ska säkra långsiktig odling och hjälpa till att nå klimatmålen. READ MORE
