  1. 1. The Unexplored Earth : Inspiring the future of mineral exploration

    University essay from Umeå universitet/Designhögskolan vid Umeå universitet

    Author : Alexandre De Bastiani; [2020]
    Keywords : design; concept; epiroc; mineral exploration;

    Abstract : Very much like the great navigations in the 14th century or the space programs, exploring remote parts of our planet is a dangerous, challenging, and unknown endeavor that drives human beings. We not only do it to find resources but also for the sake of science, looking for shreds of evidence of a past that we only speculate. READ MORE

  2. 2. Factors controlling the sorption of Cs, Ni and U in soil : A statistical analysis with experimental sorption data of caesium, nickel and uranium in soils from the Laxemar area

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emilia Johansson; [2020]
    Keywords : correlation analysis; Kd values; partition coefficient; Pearson correlation; radionuclide; soil; sorption;

    Abstract : In the fall of 2006, soils from three small valleys in the Laxemar/Oskarshamn area were sampled. A total of eight composite samples were characterized for a number of soil parameters that are important for geochemical sorption and were later also used in batch sorption experiments. READ MORE
