1. 1. Sargassum seaweed in Guadeloupe: a public health concern : An interview study in Guadeloupe, French West Indies

   Master-uppsats, Högskolan i Halmstad/Akademin för hälsa och välfärd

   Författare :Hanna Grönroos; [2023]
   Nyckelord :brown algae; Guadeloupe; health; health literacy; lifestyle; sargassum; brunalg; Guadeloupe; hälsa; hälsolitteracitet; livsstil; sargassum;

   Sammanfattning : Bakgrund Strömmar av brunalgen sargassum har drabbat Karibien i flera år, särskilt påtagligt det senaste decenniet, sedan år 2011. Den överväldiga mängden sargassum har förknippats med klimatförändringar och utsläpp av gödningsmedel i havet. LÄS MER

3. 2. Optimering av Savoniusturbinens effektivitet i marina strömmar med hjälp av CFD-analys av flödesriktare

   Kandidat-uppsats, Uppsala universitet/Elektricitetslära

   Författare :Leonard Hammar; Jacob Kovaleff Malmenstedt; [2022]
   Nyckelord :MCT; Marine Current Turbine; Savonius turbine; CFD; Ansys fluent; diffuser augmented turbine; Savoniusturbin; Marina strömmar; CFD; Ansys fluent; flödesriktare;

   Sammanfattning : The Savonius turbine is a self-starting vertical axis turbine that has a few advantages compared to other vertical axis turbines such as lower cost, lower noise and is relatively easy to manufacture. This turbine does however have a lower efficiency and is therefore less used in the electricity production than other turbines. LÄS MER

4. 3. Risk Contours for RemoteOperations Centres forMaritime AutonomousSurface Ships

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Andreas Baldhagen; Jonas Lindström; [2022]
   Nyckelord :Monitoring of autonomous vehicles; Autonomous vessels; Remote operations centers; Maritime autonomous surface ships; Land­based monitoring; Risk contours.; Risk­konturer; Fjärroperationscentraler; Marina autonoma ytfartyg; Övervakning av autonoma fordon; Autonoma fartyg; Landbaserad övervakning.;

   Sammanfattning : To monitor and control maritime autonomous surface ships in a land­based remote operations centre leads to several advantages compared to today when a whole crew is needed on board. For example, less humans would be required to control the same amount of ships, less personnel would be required to live or stay on the ship for a longtime and risk being injured or die in accidents or storms.

5. 4. Effects on wastewater due to new active pharmaceutical ingredients and products

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Marina Vik; [2019]
   Nyckelord :Pharmaceutical wastewater; wastewater treatments; BOD; COD; chemical engineering; kemiteknik; Earth and Environmental Sciences; Technology and Engineering;

   Sammanfattning : Wastewater from pharmaceutical industries can sometimes contain substances that could cause complications in the receiving wastewater treatment plant. This master thesis is about a phar-maceutical company and the wastewater from it. LÄS MER

7. 5. Autonomous Docking and Navigation of ships using Model Predictive Control

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Mao-Wei Nilsson; [2018]
   Nyckelord :;

   Sammanfattning : Autonomous shipping is a coming field, where it will be important tooperate a ship without manual intervention. Although there are manyissues yet to be solved, not the least the legal ones, it would be interestingto investigate functions that already now would be possibleto use in today’s ship operation.
