  2. 1. Muscular activity in light manual work - with reference to the development of muscle pain among computer users

    Author : Stefan Thorn; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cinderella hypothesis; myalgia; muscle rest; doublets; extensor digitorum communis muscle; motor units; computer work; intramuscular electromyography; trapezius muscle;

    Abstract : Work related musculoskeletal disorders (WMSDs) in the neck/shoulder area and the upper extremities are common among computer users, despite the relatively low muscle load levels involved. Muscle pain (myalgia), primarily experienced in the neck/shoulder area, is a frequent type of WMSD. READ MORE

  4. 2. Physics at the High-Energy Frontier : Phenomenological Studies of Charged Higgs Bosons and Cosmic Neutrino Detection

    Author : Oscar Stål; Gunnar Ingelman; Johan Rathsman; Jonathan Ellis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; Standard Model; beyond the Standard Model; supersymmetry; Higgs physics; charged Higgs boson; LHC; flavour physics; ultra-high-energy neutrinos; Askaryan effect; radio detection; lunar satellites; Elementary particle physics; Elementarpartikelfysik; högenergifysik; High Energy Physics;

    Abstract : The Standard Model of particle physics successfully describes present collider data. Nevertheless, theoretical and cosmological results call for its extension. A softly broken supersymmetric completion around the TeV scale solves several of the outstanding issues. Supersymmetry requires two Higgs doublets, leading to five physical Higgs states. READ MORE

  5. 3. It Takes Two to Tango : Bacterial heterogeneity and host cell features govern Salmonella infection

    Author : Viktor Ek; Mikael E. Sellin; Francisco García del Portillo; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; swimming; swim pattern; targetting; virulence; invasion; host-pathogen interactions; epithelium; epithelial cells; macrophages; monocytes; monolayer; flagella; genome; genetic; barcoding; discreet-invasion; shape; morphology; antibiotics; persistence; Mikrobiologi; Microbiology;

    Abstract : Salmonella enterica serovar Typhimurium (S.Tm) causes enterocolitis with significant worldwide morbidity and mortality. The general aim of this thesis is to investigate variation in host cell invasion mechanisms used by S.Tm across different host cell contexts, as well as the influence of bacterial cell-cell heterogeneity on invasion-relevant S.

  6. 4. 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.

  7. 5. Mössbauer spectroscopy under high pressures and temperatures

    Author : Elke Hålenius; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Mössbauer; high pressure - high temperature; iron; olivine; Geovetenskap; Earth sciences; Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : Iron plays a very important role in Earth materials. 57Fe- Mössbauer spectroscopy provides valuable information on the oxidation state and the near surrounding of iron atoms in crystal structures. READ MORE
