  2. 1. Effective Field Theory for QCD-like Theories and Constraints on the Two Higgs Doublet Model

    Author : Jie Lu; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD-like; effective field theory; symmetry breaking; renormalization group; two Higgs doublet model;

    Abstract : This thesis includes two topics.The first three papers is the major part of this thesis, which is about higher order calculations in the effective field theories of three QCD-like theories. These three QCD-like theories are distinguished by having quarks in a complex, real or pseudo-real representation of gauge group. READ MORE

  5. 3. Exploring the microbiota of the gastrointestinal tract

    Author : Jie Xu; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiota; Probiotics; Blood pressure; High fat diet; Oat; Green tea; Berry; Fiber; Exopolysaccharides; Ulcerative colitis;

    Abstract : Abstract: Balanced microbiota of the gastrointestinal (GI) tract is important for maintaining health of the host. Altered gut microbiota have been found to be associated with various life-style induced and other intestinal inflammatory diseases. Gut microbiota is viewed as a metabolic organ and considered as new target for therapies. READ MORE

  6. 4. A numerical model to simulate short-term beach and dune evolution

    Author : Jie Zhang; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical model; cross-shore transport; beach profile change; dune erosion; offshore mound; storms;

    Abstract : Sediment transport in the cross-shore (CS) and associated changes in the beach profile, especially during storms, have been topics of widespread concern. Since storms are often accompanied by high water levels and large waves, large quantities of sand from the beach and the dune are typically transported offshore, leading to severe beach and dune erosion, which threatens the integrity of buildings and infrastructure near the coast.
