1. 1. Colliding Galaxies in a (Nut)Shell

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

   Author : Jonathan Petersson; [2022]
   Keywords : shell galaxies; simulations; starbursts; quenching; mergers; Physics and Astronomy;

   Abstract : Galaxy interactions and mergers are natural recurring events in the current cosmological paradigm, events that often coincide with starbursts and enhanced star formation activity. To understand why that is, one can use idealised (non-cosmological) merger simulations, which provide freedom to recreate specific tidally distorted galaxies, and analysis of the time evolution and underlying physics of the star formation activity at a high spatial resolution.

3. 2. Epidotization as an Effect of Fluid Rock Interaction, Recorded by a Granitoid From Hågadalen, Uppsala

   University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

   Author : Linn Barreby; [2022]
   Keywords : Fluids; Fluid Transport; Metamorphism; Metasomatism; Saussuritization; Epidote Group; Geology; Bedrock; Fluider; Fluidtransport; Metamorfos; Metasomatism; Saussuritisering; Epidot Gruppen; Geologi; Berggrund;

   Abstract : A common driving mechanism of metamorphic processes, from which secondary mineralizations and structures develop in a protolith, is known to be a change of the immediate P-T environment that a rock resides in. A factor in this process, which is poorly understood, however, is how the presence of metamorphic fluids in a system, influences the alteration of primary igneous rocks. READ MORE

4. 3. Beaver wetland and lake effects on Francisella tularensis in Swedish landscapes and hares

   University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

   Author : Lovisa Pihlgren Hökby; [2022]
   Keywords : tularemia; francisella tularensis hola; beavers; hares; wetland restauration; epizoology; vector borne diseases;

   Abstract : The zoonotic disease tularemia is caused by the bacterium Francisella tularensis that infects both humans and wildlife in Sweden. Associations between outbreaks of tularemia and lakes and rivers have earlier been observed, and semi-aquatic rodents and mosquitoes are believed to be key species groups in the epidemiological cycle of the disease.

5. 4. Holocene lake-level changes in the Siljan Lake District – Towards validation of von Post’s drainage scenario

   University essay from Lunds universitet/Geologiska institutionen

   Author : Savvas Paradeisis-Stathis; [2020]
   Keywords : Lake Siljan; Dalarna; basin isolation; catastrophic drainage; early Holocene; lake sediments; XRF scanning; C N ratio; magnetic susceptibility; pollen; Ancylus Lake; Earth and Environmental Sciences;

   Abstract : The Dalarna province in south-central Sweden shows a great variety of geological evidence from the Late Quaternary. A peculiar deglaciation pattern, along with unique hydrological conditions, has left a lot of space for speculations over the palaeoenvironmental conditions during the early Holocene. READ MORE

6. 5. Cross-comparison of Non-Linear Seismic Assessment Methods for Unreinforced Masonry Structures in Groningen

   University essay from KTH/Betongbyggnad

   Author : Viktor Peterson; Zihao Wang; [2020]
   Keywords : Non-linear time-history analysis; non-linear pushover analysis; N2-method; equivalent frame model; continuum model; numerical seismic assessment; unreinforced masonry buildings; Olinjär tids-historikanalys; olinjär stjälpningsanalys; N2-metoden; ekvivalent rammodell; kontinuumelement modell; numerisk jordbävningsanalys; oarmerade murverksbyggnader;

   Abstract : A large amount of low-rise unreinforced masonry structures (URM) can be found in Groningen, the Netherlands. More and more induced earthquakes with short duration have been detected in this region due to gas exploitation. READ MORE
