1. 1. Mussel farming along the south-Swedish coasts - a possible solution to eutrophication?

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :David Trulsson; [2023]
   Nyckelord :Mussel farming; Aquaculture; Spatial suitability analysis; Eutrophication; Baltic Sea; Biology and Life Sciences; Earth and Environmental Sciences;

   Sammanfattning : The concept of mussel farming as a mitigator to nutrient pollution is steadily spreading. The southernmost part of Sweden borders the Baltic Sea where the water quality differs between the costs, however, all are affected by eutrophication. LÄS MER

3. 2. Improving proton therapy planning with photon-counting spectral computed tomography

   Master-uppsats, KTH/Fysik

   Författare :Karin Larsson; [2023]
   Nyckelord :Proton therapy; Medical imaging; Computed Tomography; Protonterapi; Medicinsk avbildning; Datortomografi;

   Sammanfattning : Proton radiation therapy is an alternative to conventional photon radiation therapy, which accounts for the majority of radiation treatments today. The rationale for using protons in radiation therapy lies in their dose deposition properties; photons deposit a radiation dose inversely proportional to the energy, and therefore tissue depth, while protons exhibit a sharp Bragg peak when traversing matter.

4. 3. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

   Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Författare :Francisco Gonçalves Jorge Dias de Carvalho; [2023]
   Nyckelord :Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

   Sammanfattning : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. LÄS MER

5. 4. Antal tvärsektioners påverkan på djupmodeller producerad av SeaFloor HydroLite ™ enkelstråligt ekolod : En jämförelse mot djupmodeller producerad av Kongsberg EM 2040P MKII flerstråligt ekolod

   M1-uppsats, Högskolan i Gävle/Samhällsbyggnad

   Författare :Linnéa Hägg; Simon Stenberg Jönsson; [2023]
   Nyckelord :Single beam echo sounder; multi beam echo sounder; cross lines; depth map; Enkelstråligt ekolod; flerstråligt ekolod; tvärsektioner; djupkarta;

   Sammanfattning : Hydroakustiska mätningar har gjorts i nästan två hundra år. Det kan liknas med topografiska mätningar på land och visar hur sjö- eller havsbottnar ser ut. LÄS MER

7. 5. Wave Damping by Vegetation at Bunkeflo Salt Meadows - Applying an empirical model based on plant biomass

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Charlie van Houwelingen; Timothy Ley; [2021]
   Nyckelord :Coastal protection; nature-based solutions; salt marshes; salt meadows; sea level rise; wave damping; Technology and Engineering;

   Sammanfattning : Future sea level rise due to climate change increases the risk of coastal flooding and thus necessitates the building of dikes and other protective structures. Coastal vegetation can reduce the impact of waves on such structures by dissipating wave energy and hence reduce incoming wave heights. LÄS MER
