11. Family symmetries and radiative corrections in multi-scalar extensions of the Standard Model
Sammanfattning : The four articles contained in this thesis all concern aspects of model building beyond the Standard Model (BSM). While Paper I mainly serves as a ``tool paper'' in which the results can be used to simplify certain calculations of one-loop effects from new heavy particles, Paper II--IV all deal with consequences of family symmetries in several BSM scenarios.

12. Den goda skolan : i lagens namn eller en trygghetens famn? Diskurser om skolproblem i lokal media och bland skolverksamma
Sammanfattning : This thesis focuses on representations of school problems in Swedish local newspapers and how these can be understood in terms of discourses about “the good school”. The thesis also focuses on how these discourses are manifested among and resisted by school professionals, and on the potential consequences for schools. LÄS MER
13. Non-equilibrium dynamics of exactly solvable quantum many-body systems
Sammanfattning : Recent experimental advances on ultracold atomic gases and trapped ions have made it possible to simulate exactly solvable quantum systems of interacting particles. In particular, the feasibility of making rapid changes, so-called quantum quenches, to such set-ups has allowed experimentalists to probe non-equilibrium phenomena in closed interacting quantum systems.

14. Extreme Storms in the North Atlantic and Europe
Sammanfattning : A study of the most extreme cyclones affecting the North Atlantic and Europe is presented with particular focus on extreme windstorms over the densely populated area of Western Europe, whose associated high surface wind speeds are capable of causing extensive structural damage and occasionally a loss of life.A novel cyclone identification and tracking algorithm is presented which explicitly recognises ‘multi-centre cyclones’ (MCCs), defined as cyclonic systems which contain two or three sea-level pressure minima.

15. C–H activation through late transition metal cyclometallation. Addressing selectivity and reactivity problems
Sammanfattning : The ligand-directed C—H activation relies on a coordinating donor atom being in proximity to the C—H bond activated. Cyclometallation of 2-(1-naphthyl)-pyridine – a substrate containing both γ- and δ-positions in proximity to the directing nitrogen atom – was studied. LÄS MER
