  3. 2. Displacement Washing in the Sulfate Pulp Mill

    Författare :Gunnar Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal ions; Kraft pulp; models; diffusion; filter cakes; sorption; temperature; lignin; fibers; washing; lime mud; chemical recovery; displacement; pulp washing;

    Sammanfattning : Displacement washing is an operation in which it is possible to wash solid-phase particles with a minimum of water. In a sulfate pulp mill, the main application is the pulp washing, but lime mud washing also occurs in the chemical recovery. The washing consumes a great deal of water. LÄS MER

  4. 3. Correction for displacement artifacts in phase contrast magnetic resonance imaging

    Författare :Per Thunberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Magnetic resonance imaging (MRI) is an imaging modality which provides good conditions for studies of flow and motion in the cardiovascular system. A variety of different imaging pulse sequences enables both anatomical and functional studies. LÄS MER

  5. 4. Negotiating Involuntary Resettlement : A study of local bargaining during the construction of the Zimapán dam

    Författare :Inga-Lill Aronsson; Jan-Åke Alvarsson; Lucia Ann McSpadden; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Ethnology; Mexico; resettlement; displacement; peasants; negotiations; time; space; development; Etnologi; Ethnology; Etnologi; Kulturantropologi; Cultural Anthropology;

    Sammanfattning : This dissertation seeks to present and analyze the negotiation process between the Mexican Power Board (CFE) and the peasants of Ejido Vista Hermosa, who were displaced by the building of the Zimapán dam in central Mexico. I use these negotiations as a focal point to identify the strategies, the reasoning, the priorities, and the conflicts of interest of the two main actors in the resettlement project. LÄS MER

  7. 5. Multiphase Contamination in Rock Fractures : Fluid Displacement and Interphase Mass Transfer

    Författare :Zhibing Yang; Auli Niemi; Fritjof Fagerlund; Tissa Illangasekare; Insa Neuweiler; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multiphase flow; dissolution; mass transfer; invasion percolation; immiscible displacement; fractured media; groundwater contamination; non-aqueous phase liquid; curvature; Hydrology; Hydrologi;

    Sammanfattning : Multiphase flow and transport in fractured rock is of importance to many practical and engineering applications. In the field of groundwater hydrology an issue of significant environmental concern is the release of dense non-aqueous phase liquids (DNAPLs) which can cause long-term groundwater contamination in fractured aquifers.
