  1. 1. Simple sl_{n+1}-module structures on U(h)

    Författare :Jonathan Nilsson; Volodymyr Mazorchuk; Olivier Mathieu; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We study the category M consisting of U(sl_{n+1})-modules whose restriction to U(h) is free of rank 1, in particular we classify isomorphism classes of objects in M and determine their submodule structure. This leads to new sl_{n+1}-modules. LÄS MER

  3. 2. Simple Modules over Lie Algebras

    Författare :Jonathan Nilsson; Volodymyr Mazorchuk; Erhard Neher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lie algebra; Representation; Simple module; Non-weight module; Classification; Construction; Mathematics; Matematik;

    Sammanfattning : Simple modules are the elemental components in representation theory for Lie algebras, and numerous mathematicians have worked on their construction and classification over the last century. This thesis consists of an introduction together with four research articles on the subject of simple Lie algebra modules. LÄS MER

  4. 3. Occupational exposure to fluorinated ski wax

    Författare :Helena Nilsson; Jonathan W. Martin; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perfluorinated; polyfluorinated; FIS; occupational exposure; ski wax; biotransformation; metabolism; fluorotelomer alcohol; fluorotelomer acid; aerosol; dust; UPLC MS-MS; GC MS-MS; Kemi; Chemistry;

    Sammanfattning : Per- and polyfluorinated substances (PFAS) are used in the production of ski wax to reduce the friction between the snow and the ski. In this occupational study of ski wax technicians’ exposure to PFAS and particulate aerosol we have collected whole blood (wb) (n =94), air (n =84) and aerosol (n =159) samples at World Cup events from 2007-2011.

  5. 4. Atmospheric dynamics and the hydrologic cycle in warm climates

    Författare :Henrik Carlson; Rodrigo Caballero; Johan Nilsson; Jonathan L. Mitchell; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; superrotation; early Eocene; warm climates; Madden-Julian Oscillation; the hydrologic cycle; vegetation sensitivity; large-scale circulation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Past warm climates represent one extreme of Earth's known climate states. Here, we study warm climates in both idealized simulations and full-complexity general circulation model (GCM) simulations of the early Eocene epoch, approximately 50 million years ago. LÄS MER

  7. 5. Host-pathogen interactions during tick-borne flavivirus infection : pathogenesis, tropism and tools

    Författare :Ebba Rosendal; Anna K. Överby Wernstedt; Emma Nilsson; Jonathan D. Gilthorpe; Sonja M. Best; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tick-borne encephalitis virus; Langat virus; pathogenesis; type I interferons; central nervous system; neuroinflammation; structural proteins; Infectious Diseases; infektionssjukdomar; mikrobiologi; Microbiology;

    Sammanfattning : Tick-borne encephalitis virus (TBEV) is a neurotropic member of the genus Flavivirus. It may transmit to humans through the bite of an infected tick or consumption of unpasteurized dairyproducts, and causes tick-borne encephalitis (TBE). TBE constitutes a significant health burden in Eurasia, with more than 10,000 cases reported every year. LÄS MER
