  1. 16. Investigation of different ventilation profiles to avoid stratification in Nearly Zero Energy Buildings

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Alazne Irene Varela Santana; [2023]
    Keywords : stratification; water model; comfort; mixing; temperature; potential energy; net zero energy building;

    Abstract : This research paper examines possible solutions for the problems that warm air heating is suffering in Nearly Zero Energy Buildings. These NZEBs are passive houses constructed to have high energy efficiency where the quantity of power used is equal to the power created annually, produced locally or in the surroundings by renewable energy sources.

  3. 17. Evaluation of Woodmer/plastic composites

    University essay from KTH/Fiber- och polymerteknologi

    Author : Leon Ahlström; [2023]
    Keywords : Extrusion; Woodmer; Flame test; Tensile test; Composites; Extrudering; Woodmer; Flamtest; Dragtest; Kompositer;

    Abstract : Plast ger otroliga möjligheter i form av stor variation för materialanvändning. Tyvärr sker det dock på bekostnad av miljön då de ackumuleras i naturen. En kompromiss mellan hållbarhet och fortsatt plastanvändning skulle kunna vara att använda biomassa som fyllnadsmaterial i plastkompositer istället för plast. READ MORE

  4. 18. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Isa Clementsson; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

  5. 19. Study of mixing and exchange in a drinking water reservoir using CFD modeling

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Nadja Rabizadeh; [2023]
    Keywords : CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

    Abstract : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. READ MORE

  6. 20. Mildly nutritious or mild and nutritious : a study on the effect of low phenolic content in wheat and rye kernels and its sensory effect on whole grain breads

    University essay from SLU/Department of Molecular Sciences

    Author : Julia Kullberg; [2023]
    Keywords : White rye; white wheat; low phenolic flour;

    Abstract : Recent studies on the dietary habits of the Swedish population show that only 30% reaches the recommended levels of dietary fibres. As a high fiber intake is associated with health benefits and a decrease in the risk of developing lifestyle disease, there may be a need for new types of fibre and wholegrain products. READ MORE
