  1. 1. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Elsa Muller; [2023]
    Nyckelord :Acidification; Warming; Deoxygenation; Foraminifera; Ammonia confertitesta T6 ; Culture Experiment; Trace elements; Earth and Environmental Sciences;

    Sammanfattning : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. LÄS MER

  3. 2. Den självklara amningens komplexitet. : En osteoarkeologisk studie om amning och dess problematik.

    Kandidat-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Cora Adolfsson; [2022]
    Nyckelord :Breastfeeding; Substitute; Isotope analysis; C N; Sr Ca; Malnutrition; Animal milk.;

    Sammanfattning : This bachelor’s essay aims to discuss breastfeeding and complications related to breastfeeding within archaeological contexts. Why complications have arisen when such a natural act is per- formed and how individuals have tried to manage them. LÄS MER

  4. 3. Novel Scale Chemistry of Salmo Salar L. : New Linkage of Otolith and Scale Chemistry to M74 Reproductive Disorder

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Michelle Von Ehr; [2022]
    Nyckelord :Thiamine; M74; Salmon; Otolith chemistry; Scale chemistry; laser-ablation coupled inductively plasma mass spectrometry;

    Sammanfattning : Baltic salmon suffer from maternally transmitted M74 reproductive disorder, which causes yolk-sac fry mortality due to thiamine deficiency. This study investigates trace elemental analyses of Baltic salmon applied on otoliths and scales and their possible link to identifying M74. LÄS MER

  7. 5. Major and trace element geochemical analysis of norites in the Hakefjorden Complex to constrain magma source and magma plumbing systems

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Aodhan Barrett; [2020]
    Nyckelord :Anorthosite; norite; Plagioclase; Hakefjorden Complex; Sweden; Trace Elements; Geochemistry; Magma Origin; Earth and Environmental Sciences;

    Sammanfattning : Major and trace element data taken from plagioclase crystals from anorthosites and related rock units in the Hakefjorden Complex located off the west coast of Sweden were investigated for the purposes of constraining magma chamber processes and the source of the magma. Although the anorthosite units were completely homogenous in regards to its chemistry, the plagioclase in the associated norite and ilmenite-leuconorite units showed substantial variation. LÄS MER
