  1. 1. Fines Content and Density Effects on Tailings Behaviour : A Laboratory Study on Geotechnical Properties

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Viktor Wiklund; [2018]
    Nyckelord :strength; compressibility; permeability; anrikningssand; hållfasthet; konsolidering; permeabilitet;

    Sammanfattning : Tailings are a rest product from the extraction of metals and minerals, and is therefore produced in large volumes by all mining companies. One common way to store tailings material is to deposit it as a hydraulic slurry on a tailings impoundment, where the tailings are held in place by tailings dams. LÄS MER

  3. 2. The Influence of Oxygen on Nanowire Surface Structure and Electronic Properties

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Viktor Abelin; [2015]
    Nyckelord :Scanning tunneling microscopy; STM; Auger electron spectroscopy; AES; nanowire; hydrogen cleaning; Physics and Astronomy;

    Sammanfattning : This thesis investigates the possibilities for setups measuring how the surface structure of nanowires (NWs) influences their electric properties. For this the abilities to clean surfaces and detect nanowires (NWs) are examined, and an attempt to build a setup is made. LÄS MER

  4. 3. Bottensubstratets inverkan på föryngring av Flodpärlmussla

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Viktor Boström; Hjalmar Holm; [2012]
    Nyckelord :Margaritifera margaritifera; freshwater pearl mussel; regeneration; bottom substrates;

    Sammanfattning : The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. LÄS MER
