  1. 1. Sound propagation around off-shore wind turbines

    Detta är en avhandling från Stockholm : Byggvetenskap

    Författare :Lisa Johansson; KTH.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind turbine noise; off-shore wind powe; long-rage sound propagation; parabolic equation; scattering; water waves; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik;

    Sammanfattning : Low-frequency, long-range sound propagation over a seasurface has been calculated using a wide-angel Cranck-NicholsonParabolic Equation method. The model is developed toinvestigate noise from off-shore wind turbines. Thecalculations are made using normal meteorological conditions ofthe Baltic Sea. LÄS MER

  2. 2. Calcium and Phospholipases in Orexin Receptor Signaling

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lisa Johansson; Uppsala universitet.; [2008]
    Nyckelord :Physiology; orexin; receptor; calcium; phospholipase; cell signaling; GPCR; Fysiologi;

    Sammanfattning : The neuropeptides orexin-A and -B act as endogenous ligands for G-protein-coupled receptors (GPCRs) called OX1 and OX2 receptors. Previous observations have established that orexin receptors have an ability to couple to different G-proteins and signaling pathways and induce Ca2+ elevations via both receptor-operated Ca2+ channels (ROCs) and store-operated Ca2+ channels (SOCs).
