  1. 1. Improved Energy Efficiency in the Aluminium Industry and its Supply Chains

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Joakim Haraldsson; Magnus Karlsson; Maria Johansson; Max Åhman; [2020]

    Sammanfattning : Energy is an essential resource in the daily lives of humans. However, the extraction and use of energy has an impact on the environment. The industrial sector accounts for a large share of the global final energy use and greenhouse gas (GHG) emissions. The largest source of industrial GHG emissions is energy use. LÄS MER

  2. 2. On avoiding and completing colorings

    Detta är en avhandling från Umeå : Umeå University

    Författare :Lan Anh Pham; Klas Markström; Carl Johan Casselgren; Victor Falgas-Ravry; Roland Häggkvist; Kimmo Eriksson; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graph coloring; precoloring; list assignment;

    Sammanfattning : All of my papers are related to the problem of avoiding and completing an edge precoloring of a graph. In more detail, given a graph G and a partial proper edge precoloring φ of G and a list assignment L for every non-colored edge of G, can we extend φ to a proper edge coloring of G which avoids L? In Paper I, G is the d-dimensional hypercube graph Qd, a partial proper edge precoloring φ and a list assignment L must satisfy certain sparsity conditions.

  3. 3. Microbially mediated formation of birnessite-type manganese oxides and subsequent incorporation of rare earth elements, Ytterby mine, Sweden

    Detta är en avhandling från Stockholm : Department of Geological Sciences, Stockholm University

    Författare :Susanne Sjöberg; Christophe Dupraz; Rienk Smittenberg; Volker Brüchert; Helena Filipsson; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microbial diversity; manganese oxides; birnessite; rare earth elements; subterranean; Ytterby mine; geokemi; Geochemistry;

    Sammanfattning : Microbes exert extensive control on redox element cycles. They participate directly orindirectly in the concentration and fractionation of elements by influencing the partitioningbetween soluble and insoluble species. LÄS MER

  4. 4. Att leda ett utmanande skoluppdrag i förändring Rektorers ledarskap i likabehandlingsarbete

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Greta Lindberg; Åsa Gardelli; Marie Wrethander; Pia Skott; [2019]

  5. 5. Batch Sorption Studies of Aqueous Cadmium and Lead from Contaminated Water onto Selected Biosorbents

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Grace Kizito Bakyayita; Ann-Catrine Norrström; Robinah N. Kulabako; Maimuna Nalubega; Roger Thunvik; Ann-Margret Hvitt Strömvall; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biosorbents; cadmium; competitive uptake; Freundlich; pseudo-second-order kinetics; Langmuir; lead; remediation; risks; speciation; toxicity effects; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Groundwater, wastewater, surface runoff and surface water samples from Lake Victoria basin, Uganda was assessed for trace metals contamination. Untreated, base-treated and peroxide-treated biosorbents from Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were investigated for removal of selected trace metals from contaminated water in batch studies.
