1. 1. Can blue mussel shells be used for retrospective 14C-analysis in the marine environment of nuclear power plants?

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

   Author : Sofia Bjarheim; [2024]
   Keywords : Radionuclide; Marine Environment; Blue Mussels; 14C; Nuclear Power Plant; Physics and Astronomy;

   Abstract : Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. READ MORE

3. 2. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Nicolai Laufer; [2023-06-21]
   Keywords : ;

   Abstract : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. READ MORE

4. 3. Evaluating the Performance of Propulsion System Elements in an Aerospace Company

   University essay from KTH/Kraft- och värmeteknologi

   Author : David Fredouelle; [2023]
   Keywords : Turbomachinery; injector; test campaign; cryogenic; rocket engine; test bench; cold flow; Turbomaskin; injektor; testkampanj; kryogen; raketmotor; testbänk; kallt flöde;

   Abstract : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions.

5. 4. Impact of wetland restoration on river discharge - A case study of Bråån, Skåne, Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ardis Luda; [2023]
   Keywords : wetlands; wetland restoration; HYPE model; river discharge; Sweden; land use change; flooding; hydrological modeling; Earth and Environmental Sciences;

   Abstract : Land use change is a factor not often considered when modeling river discharge in regard to future flood risk. The restoration of wetlands is an ongoing land use change which affects water storage capacity in the soils of a catchment and could lead to lower flows in rivers. READ MORE

6. 5. CFD-modeling of labyrinth weir flood discharge with ice cover

   University essay from KTH/Betongbyggnad

   Author : Erik Isberg; [2023]
   Keywords : ;

   Abstract : A labyrinth weir is a hydraulic structure built with a purpose to increase the discharge capacity compared to linear weirs, while maintaining the same water level upstream. Construction of labyrinth weirs is vital in a future with more unpredictable flows. READ MORE
