  1. 1. Early Pottery Use among Hunter-Gatherers around the Baltic Sea

    Författare :Vasiliki Papakosta; Sven Isaksson; Ole Stilborg; Åsa Maria Larsson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Early Pottery Use; Hunter-Gatherers; Baltic; Late Mesolithic; Ceramics; Ertebølle; Narva; Early Comb Ware; Lipid Extraction; Lipid Residue Analysis; Molecular Analysis; Stable Carbon Isotope Analysis; Elemental Analysis; Mineralogical Analysis; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

    Sammanfattning : This thesis aims to provide an understanding of the dynamics underlying the adoption of pottery by pre-agrarian hunter-gatherer cultural groups around the Baltic Sea. The focus is on three approximately contemporaneous early pottery traditions of the region (ca. LÄS MER

  3. 2. The Kirunavaara hangingwall : a geophysical and petrophysical analysis

    Författare :Mai-Britt Mose Jensen; Håkan Mattsson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Sammanfattning : Underground mining of the Kirunavaara iron mineralization is causing large-scale deformation of the hangingwall of the orebody. To understand and possibly even predict this deformation, a good understanding of the elastic and mechanical properties of the rocks in the hangingwall is necessary. LÄS MER

  4. 3. Influence of Composition and Pore Geometry on Immiscible Fluid Flow through Greensands: Development of Neutron Transmission Methods and Image Analysis

    Författare :Mikael Solymar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pore geometry; image analysis; fluid flow; petrography; greensand; porosity; glauconite; permeability; neutron transmission methods; fluid saturation;

    Sammanfattning : The effect of the mineralogical composition and pore geometry of sediments on the distribution as well as the flow of immiscible fluids are of importance when evaluating petroleum reservoirs. Greensand containing the clay mineral glauconite is a complex reservoir rock type. LÄS MER

  5. 4. Mineralogical influence on leaching behaviour of steelmaking slags : a laboratory investigation

    Författare :Fredrik Engström; Pekka Taskinen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : The Swedish steelmaking industry produces large amounts of by-products. In 2008, the total amount of slag produced reached approximately 1,300,000 metric tons, of which 20% was deposited. LÄS MER

  7. 5. Mineralogical, chemical and textural properties of the Malmberget iron deposit : a process mineralogically characterisation

    Författare :Cecilia Lund; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : This thesis combine two different but closely connected disciplines in a mining process to each other, ore geology and process mineralogy by studying mineralogical-textural features of the ore and the ore concentrate in an apatite iron ore deposit in Malmberget, Sweden. Apatite iron ore deposits (Kiruna type) exist in a few places around the world and the two most important deposits are mined by LKAB at Kiruna and Malmberget. LÄS MER
