  1. 1. The effect of nozzle geometry on bubble formation : Physical modeling by air in a water tank

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

    Författare :Mhd Osman Bernieh; [2023]
    Nyckelord :Nozzle geometry; bubble formation; water tank model; bubble flow; Munstycksgeometri; bubbelbildning; vattentankmodell; bubbelflöde;

    Sammanfattning : The bubble flow is used for different application in steel production and refining processes. It plays in indispensable role in the ladle refining process such as for homogenization and inclusion removal. Hence, it is important to understand the effect of the nozzle outlet geometry on the bubble formation. LÄS MER

  3. 2. Production of succinic acid by Actinobacillus succinogenes in attached-growth bioreactors and dynamic modelling of biofilm formation

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Henrik Östberg; [2023]
    Nyckelord :Actinobacillus succinogenes; Succinic acid; Biofilm; Attached-growth bioreactor; Dynamic modelling; Cell cultivation; Applied microbiology; Biology and Life Sciences;

    Sammanfattning : Actinobacillus succinogenes is a microorganism is a very efficient producer of succinic acid, a chemical with a wide range of industrial applications. The bacterium is prone to form biofilm, a flocculation of cells attached to a surface. LÄS MER

  4. 3. Primordial Gravitational Waves and ultra-light Dark Matter in a complex singlet extended Standard Model

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Sara Wildenor; [2021]
    Nyckelord :theoretical physics; gravitational waves; dark matter; complex singlet extended standard model; LISA; BBO; DECIGO; Physics and Astronomy;

    Sammanfattning : In this thesis, the consequences of extending the internal symmetries of the standard model with a complex singlet scalar field, are investigated in terms of dark matter phenomenology and the possibility of primordial gravitational wave detection utilizing space based laser interferometry. The scalar potential of the model is constructed with a Z2 symmetry, which allows for the retainment of a linear and a quadratic coupling parameter, as well as a stable dark matter candidate, and an additional non-zero vacuum expectation value for the real component of the scalar field.

  5. 4. Quantitative Easing and Bubble Formation in Real-Estate : A study of the relationship between novel monetary policies and speculative bubbles in the Swedish real-estate market

    Master-uppsats, Linköpings universitet/Nationalekonomi; Linköpings universitet/Filosofiska fakulteten

    Författare :Axel Öhlund; Anna Domnina; [2021]
    Nyckelord :Large-scale asset purchasing program; Quantitative easing; Vector Autoregression; Riksbanken; Housing Bubble; Speculative Bubbles; Unconventional Monetary Policy;

    Sammanfattning : This thesis aims to study how much of price appreciations on the Swedish real-estate market in recent times have been fundamentally warranted, as well as if the unconventional monetary policies implemented by the Swedish central bank have had any interaction with these price escalations. The methodology employed to research this is divided into two parts. LÄS MER

  7. 5. Lignin/Carbon Fibre Composites

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Ali Al Husseinat; Emma Persson; Ran Carlhamn Rasmussen; Filip Rynkiewicz; [2021]
    Nyckelord :Kraft lignin; Solvent fractionation; Selective allylation; Lignin based composite material; Thiol-ene thermoset;

    Sammanfattning : The market is in great need of more environmentally friendly alternatives to fossil-based composite materials to obtain a more sustainable future. Lignin is the second most common biopolymer and is a byproduct in the pulping and paper industry. LÄS MER
