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

    Master-uppsats, Uppsala universitet/Berggrundsgeologi

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

    Sammanfattning : 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.

  3. 22. In-medium width of the η' meson

    Master-uppsats, Kärnfysik

    Författare :Carl Niblaeus; [2013]
    Nyckelord :Eta prime meson; width; finite temperature; lifetime; QCD; chiral perturbation theory; Eta prime meson; vidd; ändlig temperatur; livstid; QCD; kiral störningsteori;

    Sammanfattning : In this master’s thesis the width of the  meson is studied as a function of temperature. We consider a background medium consisting of a pion gas and assume a vanishing net baryon chemical potential. LÄS MER

  4. 23. How was the carbon balance of Europe affected by the summer 2003 heat wave? : a study based on the use of a dynamic global vegetation model; LPJ-GUESS

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Nzung Seraphine Ebang; [2011]
    Nyckelord :climate change; carbon balance; Europe; heat waves; LPJ-GUESS; drought; terrestrial ecosystems; Earth and Environmental Sciences;

    Sammanfattning : Extreme events are believed to become frequent, intense and long lasting with climate change. An example of such extreme event is the record breaking summer 2003 heat wave. The 2003 heat wave, accompanied by drought conditions, had severe impacts on the European terrestrial ecosystems. LÄS MER

  5. 24. Relating interannual variability of atmospheric CH4 growth rate to large-scale CH4 emissions from northern wetlands

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Sophie Rychlik; [2009]
    Nyckelord :temperature sensitivity; interannual variability; emission sources; CH4; northern wetlands; physical geography; July; atmospheric growth rate; Earth and Environmental Sciences;

    Sammanfattning : Metan (CH4) är en av de viktigaste växthusgaserna i atmosfären och dess kraftiga ökning har bidragit till den uppvärmning som vi har upplevt fram till idag. Sedan mitten av 1980-talet påvisar mätningar att metantillväxten i atmosfären har börjat fluktuera från år till år. Orsakerna till detta är omstridda och ännu inte klargjorda. LÄS MER

  7. 25. Lokala miljöförändringar i samband med en plötslig havsyteförändring ca 8200 år före nutid vid Kalvöviken i centrala Blekinge

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ammy Göransson; [2006]
    Nyckelord :LOI; mineral magnetism; pollen analysis; macrofossil analysis; sea level change; 8.2 kyr event; glödförlust; mineralmagnetism; pollenanalys; havsyteförändring; makrofossilanalys; Blekinge; Earth and Environmental Sciences;

    Sammanfattning : A sediment transect based on ten corings were performed with a Russian peat corer in the aldercarr at Kalvöviken on the Biskopsmåla Peninsula in central Blekinge. Three parallel sediment cores were collected at the master coring point. LÄS MER
