  1. 1. Social Identity Recategorization: Comparing National Reconciliation Initiatives in Burundi and Rwanda

    Master-uppsats, Uppsala universitet/Institutionen för freds- och konfliktforskning

    Författare :Cathinca Verwey; [2021]
    Nyckelord :post-conflict; reconciliation; social identity recategorization; Rwanda; Burund;

    Sammanfattning : After the cessation of violent conflict, societies have to undergo several changes to re-establish asense of harmony and repair the broken intergroup relationships. These changes can be summarized as the process of reconciliation. LÄS MER

  3. 2. Characterizing magnetic susceptibility and remanent magnetization of magnetite and hematite rich drill-core samples at Blötberget

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Andreas Bjork; [2018]
    Nyckelord :Verwey; Morin; Curie; Néel; magnetite; hematite; alteration; iron-ore; quality control; kappabridge; hysteresis; susceptibility; anisotropy; Verwey; Morin; Curie; Néel; magnetit; hematit; oxidation; järnmalm; kvalitetskontroll; kappabridge; hysteresis; susceptibilitet; anisotropi;

    Sammanfattning : Laboratory magnetic measurements are used to develop a methodology to characterize the Kiruna-type Rare Earth Elements (REE) bearing apatite iron-oxide deposits at Blötberget in central Sweden. This high-grade ore deposit is known to have sharp boundaries between lens shaped main ore bodies of magnetite-rich ore, and a complex hematite-rich ore associated with pegmatites and skarn formation.

  4. 3. X-ray diffraction studies on complex metal oxides

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

    Författare :Albin Linder; [2015]
    Nyckelord :reciprocal space; compass; x-ray diffraction; XRD; magnetite; Physics and Astronomy;

    Sammanfattning : The ambition of this project is to assist in the pursuance of understanding the metal to insulator transition found in magnetite at ~120 K. The transition is itself very complex and links together the charge order, orbital order and lattice distortion of magnetite with its magnetic properties. LÄS MER

  5. 4. Mobilization and transport of different types of carbon-based engineered and natural  nanoparticles through saturated porous media

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Maryeh Hedayati; [2014]
    Nyckelord :Nanoparticle; MWCNT; C60; Transport and mobilization; DLVO theory; Ionic strength; Input concentration; Clean-bed filtration theory; Column test;

    Sammanfattning : Carbon –based engineered nanoparticles have been widely used due to their small size and uniquephysical and chemical properties. They can dissolve in water, transport through soil and reach drinkingwater resources. LÄS MER
