  1. 1. Exploring the application of neural networks in predictions of nuclear binding energies

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Martin Waites; [2020]
    Keywords : neural networks; drip-line; nuclear physics; binding energy; exotic nuclei; Hartree-Fock-Bogolyubov; Physics and Astronomy;

    Abstract : In this project the locations of the proton and neutron drip-lines are predicted using neural networks and theoretical data obtained by applying the HFBTHO program. For each of the neural networks a comparison is made between neural network predictions and experimental data in the region experimental data exists. READ MORE

  3. 2. Iron and Oxygen Isotope Signatures of Magnetite in Iron Ore of Kiruna Type

    University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

    Author : Malin Andersson; [2020]
    Keywords : IOA-deposits; magnetite; SIMS; EBSD; Fe- and O isotopes; laser fluorination;

    Abstract : Stable isotope analysis of iron and oxygen isotopes in magnetite of Kiruna-type from Sweden and Chile have been conducted to further the understanding of the formation, and advance the analysis methods of these deposits. For this, data from SIMS (secondary ion mass spectroscopy), EBSD (electron backscatter diffraction) and triple oxygen analysis (by laser fluorination) are used. READ MORE

  4. 3. Osteological Markers of Nutritional Stress on the Swedish Island of Öland: Physiological Effects of Environmental Fluctuations during the Scandinavian Iron Age

    University essay from Lunds universitet/Arkeologi

    Author : Claire Maeve Callahan; [2020]
    Keywords : Old World Drought Atlas; Dendroclimatology; Nutrition; Osteology; Multiple Correspondence Analysis; Skeletal Pathology; Dietary Isotopes; Environmental Reconstructions; Historic Climate; Iron Age; Sweden; Baltic Region; History and Archaeology;

    Abstract : The shift to agriculture as the main form of subsistence practice allowed past peoples the freedom and potential to exploit their natural and man-made environment for personal and societal gain. Decades of archaeological excavations conducted on the Swedish island of Öland have amassed a wealth of information regarding the subsistence and settlement patterns of Iron Age societies. READ MORE

  5. 4. A lithogeochemical study of northern Sweden and the Kiruna and Malmberget iron-apatite ore deposits

    University essay from Uppsala universitet/Berggrundsgeologi

    Author : Jon Lundh; [2014]
    Keywords : REE; trace elements; iron-apatite ore deposit; suite; oxygen isotopes; magnetite; Kiruna; Malmberget; Haparanda; Edefors; Perthite-monzonite;

    Abstract : The iron apatite mineralizations of northern Sweden are mainly situated in supracrustal rocks and are thought to have formed during approximately the same time as the major plutonic suites in northern Sweden. In this thesis the Malmberget iron apatite ore deposit have been compared to the Kiruna iron apatite ore deposit to see whether the role of hydrothermal processes are different between the two ore districts.

  6. 5. Oxygen and iron isotope systematics of the Grängesberg Mining District (GMD), Central Sweden

    University essay from Berggrundsgeologi

    Author : Franz Weis; [2013]
    Keywords : Grängesberg; Apatite-iron oxide ore; oxygen isotopes; iron isotopes; Kiruna-type; Eisenisotope; Sauerstoffisotope; Eisenerz; Grängesberg; Kiruna-Typ; Apatit-järnmalm; syreisotoper; järnisotoper; Grängesberg; Kiruna-typ;

    Abstract : Iron is the most important metal for modern industry and Sweden is the number one iron producer in Europe. The main sources for iron ore in Sweden are the apatite-iron oxide deposits of the "Kiruna-type", named after the iconic Kiruna ore deposit in Northern Sweden. READ MORE
