  1. 1. Fuel Reforming for Hydrogen Production in Heavy-Duty Vehicle Applications

    Författare :Moa. Z. Granlund; Lars. J. Pettersson; Robert J. Farrauto; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aging · autothermal fuel reforming · CeO2-ZrO2 · characterization · diesel · H2-assisted HC-SCR · micro reactor · monolith; Chemical Engineering; Kemiteknik;

    Sammanfattning : The depletion of fossil fuels together with growing environmental concerns have created incitement for developing a more energy-efficient and environmentally-friendly vehicle fleet. The development towards cleaner heavy-duty vehicles started already in the 80’s with the introduction of emission legislations. LÄS MER

  2. 2. Evolutionary Analysis of the Insulin-Relaxin Gene Family from the Perspective of Gene and Genome Duplication Events

    Författare :Robert Piotr Olinski; Finn Hallböök; Mike Thorndyke; Pierre Pontarotti; Uppsala universitet; []
    Nyckelord :Neurosciences; insulin; relaxin; insulin-like protein; gene duplication; paralogous region; Ciona intestinalis; conserved synteny; ortholog; Drosophila melanogaster; Neurovetenskap;

    Sammanfattning : Paralogs arise by duplications and belong to families. Ten paralogs (insulin; IGF-1 and -2; INSL3-6 and 3-relaxins) constitute the human insulin-relaxin family. The aim of this study was to outline the duplications that gave rise to the vertebrate insulin-relaxin genes and the chromosomal regions in which they reside. LÄS MER

  3. 3. Constraining the top-Z coupling using the (ttWj)EW process with the ATLAS experiment : A search for physics beyond the Standard Model

    Författare :Nabila Ahlgren; Jörgen Sjölin; Robert Schöfbeck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; ATLAS; top physics; fysik; Physics;

    Sammanfattning : The Standard Model (SM) of particle physics, having been confirmed by numerous experiments, is one of the most successful theories in physics. It describes all known elementary particles and their interactions through the electromagnetic, strong and weak force. LÄS MER

  4. 4. Studies of the two redox active tyrosines in Photosystem II

    Författare :Nigar Ahmadova; Fikret Mamedov; Stenbjörn Styring; Robert Burnap; Uppsala universitet; []
    Nyckelord :Photosystem II; Tyrosine Z and D; proton-coupled electron transfer;

    Sammanfattning : Photosystem II is a unique enzyme which catalyzes light induced water oxidation. This process is driven by highly oxidizing ensemble of four Chl molecules, PD1, PD2, ChlD1 and ChlD2 called, P680. Excitation of one of the Chls in P680 leads to the primary charge separation, P680+Pheo-. LÄS MER

  5. 5. Analysis of the Radiation Environment on Board the International Space Station Using Data from the SilEye-3/Alteino Experiment

    Författare :Oscar Larsson; Bengt Lund-Jensen; Robert Seiringer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space Radiation; ISS; Alteino; Geant4;

    Sammanfattning : This thesis presents an analysis of the radiation environment on board the Russian section of the International Space Station (ISS) using data from the SilEye-3/Alteino experiment. As part of the analysis the efficiency and response of the SilEye-3/Alteino detector was studied. LÄS MER
