    Abstract : Clusters are finite ensembles of atoms or molecules with sizes in the nanometer regime (i.e. nanoparticles). This thesis present results on the geometric and electronic structure of homogeneous and heterogeneous combinations of atoms and molecules. READ MORE

  2. 2. TRANSMISSION AND PATHOGENESIS OF HANTAVIRUS

    Author : Lisa Pettersson; Magnus Evander; Clas Ahlm; Annika Allard; Tatjana Avšič - Županc; Umeå universitet; []
    Keywords : Puumala virus; Hantavirus; human-to-human transmission; saliva; nephropathia epidemica; NE; IgA; IgG; IgM; neutrophils; neutrophil; viremia; treatment; climate; snow cover; temperature.; medicinsk virologi; Medical Virology;

    Abstract : Hantaviruses are the causative agents of hemorrhagic fever with renal syndrome (HFRS) in Eurasia, and of hantavirus cardiopulmonary syndrome (HCPS) in the Americas. Transmission to humans usually occurs by inhalation of aerosolized virus-contaminated rodent excreta. READ MORE

  4. 4. Rare-gas Clusters Studied by Electron Spectroscopy : Structure of Heterogeneous Clusters and Effects of Electron Scattering on Auger Decay

    Author : Marcus Lundwall; Olle Björneholm; Gunnar Öhrwall; Maxim Tchaplyguine; Thomas Möller; Uppsala universitet; []
    Keywords : Physics; Nano-particles; Clusters; Heterogeneous clusters; Core-shell clusters; XPS; UPS; AES; Electron scattering; Radial structure; Surface structure; Surface sensitivity; Synchrotron radiation; Ne; Ar; Kr; Xe; Fysik;

    Abstract : In this Thesis experimental studies of nano-clusters using synchrotron radiation based photoelectron (UPS and XPS) and Auger Electron Spectroscopy (AES) are presented. The investigations may be divided into two parts where the first reports on the structure of heterogeneous two component clusters, and the second concerns electronic decay processes. READ MORE

  5. 5. Iron in the Lena River basin, NE Russia : Insights from microscopy, spectroscopy and isotope analysis

    Author : Catherine Hirst; Carl-Magnus Mörth; Per Andersson; Mats Erik Åström; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; iron; reactivity; isotopes; permafrost; river; Arctic; maringeologi; Marine Geology;

    Abstract : Iron is an important mediator of biotic and abiotic processes on the Earth’s surface, being an electron acceptor in organic matter degradation, a surface for organic matter and trace element adsorption, and a required element for enzymatic processes during primary production. Yet, the role of iron as a mediator of carbon and trace element cycling in high latitude, permafrost-dominated regions remains poorly investigated. READ MORE
