  1. 16. Holographic Wilson Loops : Quantum String Corrections

    Författare :Daniel Ricardo Medina Rincon; Konstantin Zarembo; Gianluca Grignani​; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gauge-string correspondence; AdS CFT; Wilson loops; String theory; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : The gauge-string duality has been one of the most exciting areas in theoretical physics as it connects strongly coupled field theories with weakly interacting strings. The present thesis concerns the study of Wilson loops in this correspondence. LÄS MER

  3. 17. Phylogenetic perspective on host plant use, colonization and speciation in butterflies

    Författare :Elisabet Weingartner; Sören Nylin; Niklas Wahlberg; Felix Sperling; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oscillation hypothesis; speciation; Polygonia; Celastrina; Pararge; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; zoologisk ekologi; Animal Ecology;

    Sammanfattning : In this thesis we have studied speciation in three butterfly genera Polygonia (Nymphalidae, Nymphalini), Pararge (Nymphalidae, Satyrinae) and Celastrina (Lycaenidae: Polyommatinae). In the first paper a dated phylogeny, based on molecular data, of Polygonia was constructed. We found strong conflict between the nDNA and mtDNA datasets. LÄS MER

  4. 18. Lean Implementation : the significance of people and dualism

    Författare :Halling Bengt; Lars Bengtsson; Jörgen Eklund; Lars Medbo; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Lean; leadership; management; implementation; barriers; comparison; development; health care; manufacturing;

    Sammanfattning : Lean, with its origins at the Toyota Motor Company, is a concept that is known to increase effectiveness in manufacturing. The Lean concept is now argued to be relevant not only in manufacturing but in service and health-care delivery as well. The reported results of Lean implementation efforts are divided. LÄS MER

  5. 19. Phenomenology of new Neutral Vector Bosons and Parton Distributions from Hadronic Fluctuations

    Författare :Andreas Ekstedt; Gunnar Ingelman; Johan Rathsman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QCD; Higgs; Gauge Symmetry; Standard Model; BFKL; PDF; DIS; Beyond the Standard Model; Colliders; Phenomenology; Effective Potential; Anomaly; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : The Higgs particle was first predicted in 1964, and was discovered in the summer of 2012 at the Large Hadron Collider (LHC). This discovery was the latest in a long list of successful Standard Model predictions spanning the last fifty years. LÄS MER

  7. 20. Column Development in Capillary Electrophoresis and Electrochromatography for Bioanalytical Applications

    Författare :Nina Johannesson; Jonas Bergquist; Karin Markides; Abdul Malik; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Capillary electrophoresis CE ; Capillary electrochromatography CEC ; Mass spectrometry MS ; Bioanalysis; Sample pretreatment; Sol-gel; Analytisk kemi;

    Sammanfattning : Analysis of biological samples can be a difficult task. This thesis covers a broad aspect of the analytical areas of capillary electrophoresis (CE) and capillary electrochromatography (CEC) in combination with mass spectrometry (MS) that are of great importance for achieving fast, accurate and sensitive bioanalyses.
