  1. 1. Family symmetries and radiative corrections in multi-scalar extensions of the Standard Model

    Author : Jonas Wessén; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beyond the Standard Model; Trinification; Grand Unification; Three Higgs doublet models; Coleman-Weinberg potential; Supersymmetry; Left-Right symmetry; Fysicumarkivet A:2018:Wessén;

    Abstract : 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.

  2. 2. Fatty Acyl Reductases and Fatty Acyl Desaturases. Deciphering the biosynthesis of species-specific moth female sex pheromones from common fatty acids

    Author : Åsa Hagström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Moth; pheromone; insect; evolution; fatty acyl desaturase; fatty acyl reductase; endoplasmic reticulum; fatty acid biosynthesis; GFP; heterologous expression; phylogeny; cell factory; lepidoptera;

    Abstract : Moths (Lepidoptera) are dependent on female produced pheromones, chemical signals, for attracting a mate. Pheromones are most commonly made up by saturated and/or unsaturated fatty acid derived alcohols, acetates, and/or aldehydes that are produced by a set of enzymes in the female pheromone gland.

  3. 3. Chronic Obstructive Pulmonary Disease (COPD) Epidemiological and Pan-airway Aspects

    Author : Ulf Nihlén; allergologi och palliativ medicin Lungmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory system; spirometry; nasal polyposis; nasal symptoms; prevalence; incidence; coronary heart disease; alcohol; airways; COPD; FEV1; Andningsorganen;

    Abstract : Background – Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. However, there is little information on the prevalence and particularly on the incidence of COPD. READ MORE

  4. 4. Unifying first-principles and model approaches for strongly correlated materials : Interplay between long- and short-range correlations

    Author : Fredrik Nilsson; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; first-principle methods; strongly correlated materials; GW approximation; cRPA; random-phase approximation; dynamical mean-field theory; GW DMFT; downfolding;

    Abstract : In materials with open 3$d$ and 4$f$ shells the valence electrons are relatively localized around the atoms which leads to large electron-electron correlations. These, so called strongly correlated materials, exhibit many intriguing properties such as high $T_c$ superconductivity, colossal magneto-resistance and heavy fermion behaviour. READ MORE
