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

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

    Abstract : 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.

  2. 17. High-Redshift Gamma-ray Bursts as seen by SVOM/ECLAIRs

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Miguel Llamas Lanza; [2021]
    Keywords : Gamma-ray Bursts; GRBs; compact objects; high energy; ECLAIRs; SVOM; high redshift; T90; detection biases;

    Abstract : Gamma Ray Burst (GRB) are very bright cosmological explosions signalling the catastrophic formation of a black hole. Therefore, they act like real light beacons that could be detected through-out the Universe and be used as probes to study the contents and phases of the early Universe. However, only a handful sample is known so far. READ MORE

  3. 18. Assessment of a Light-Activated Adhesive for Hernia Mesh Repair

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ludivine Amathieu; [2021]
    Keywords : Intraperitoneal laparoscopic ventral hernia repair; Light-activated adhesive; Acrylate conversion; Cross-linking quantification; Fixation strength performance;

    Abstract : Background and objectives: TISSIUM light-activated adhesive was investigated as an alternative to tissue-penetrating products to fix meshes in intraperitoneal laparoscopic ventral hernia repair. The objective of this study was to ensure efficient polymer light activation through commercial meshes and to assess the acute and chronic fixation strength of the light-activated adhesive in a porcine model in comparison to commercial fixation products.

  4. 19. Characterization and optimization of Rhodosporidium toruloides for production of lipids

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Niharika Singh; [2021]
    Keywords : chemical engineering; oily yeasts; lipids; nitrogen limitation; Technology and Engineering;

    Abstract : Oleaginous microorganisms provide an opportunity to produce oils without the use of arable land for cultivation of oil-containing plants. Oleaginous microorganisms are also capable of storing products of pharmaceutical interest alongside storing polymers, which could open new opportunities in the bioplastic industry. READ MORE
