  1. 1. Coupling between iron and humic substances in a land-sea transitional zone in the northern Baltic Sea

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Anna Osterman; [2023]
    Nyckelord :Iron; Humic substances; Dissolved organic carbon; Baltic Sea; Rivers;

    Sammanfattning : In marine ecosystems around the world, iron (Fe) is a well-studied and important trace element which has been found to stimulate phytoplankton and cyanobacteria growth, as well as limit nitrogen fixation and being essential for Legionella pneumophila which is known as the main cause of Legionnaires’ disease. Fe also contributes to the brownification of freshwater and has recently been documented to increase in concentration in rivers in Sweden. LÄS MER

  3. 2. Validation of Treponema pallidum haemoagglutination test compared with Treponema pallidum particle agglutination test

    Kandidat-uppsats, Uppsala universitet/Institutionen för medicinsk cellbiologi

    Författare :Emilia Lind; [2023]
    Nyckelord :TP-PA; TP-HA; syphilis; treponemal antibody test; nontreponemal antibody test;

    Sammanfattning : Treponema pallidum (T. pallidum) is the bacteria that causes syphilis, which is a sexually transmitted disease that might give the carrier a multisystemic infection. A combination of serological tests is needed to put a diagnosis of T. pallidum infection, because the bacteria cannot be cultured in vitro. LÄS MER

  4. 3. METABOLIC CRISIS IN humans WITH MITOCHONDRIAL DIABETES : DEVELOPMENT OF AN EX VIVO MODEL IN HUMAN BLOOD CELLS UNDER THE INFLUENCE OF ANTI-DIABETics

    Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Filippa Dahlgren; [2023]
    Nyckelord :Anti-diabetics; ATP-production; Metabolic crisis; Mitochondrial diabetes; Respiration;

    Sammanfattning : Mitochondria are found in all cells of the body except red blood cells. Mitochondria is the organelle that produces the most ATP in the body, which is the cells energy carrier. All processes in the body require energy in one way or another, hence the function of mitochondria is very important. LÄS MER

  5. 4. Evaluation of the stability of immobilized lipases from Rhizomucor miehei and Rhizopus oryzae in high oleic sunflower oil

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Jinxu Xu; [2021]
    Nyckelord :lipase; immobilization; oxidation; biotechnology; Technology and Engineering;

    Sammanfattning : Lipase is one of the most useful enzymes in food industry, which can catalyze the hydrolysis and the synthesis of esters. However, the high cost due to the poor operation stability of lipase hinders the wide use of it. LÄS MER

  7. 5. Hall Measurements at Cryogenic Temperatures

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Viktor Wallén; [2021]
    Nyckelord :Hall measurement; Hall effect; Cryoelectronics; Cryogenics; Subthreshold slope; Subthreshold swing; Mobility; Carrier Concentration; Resistivity; Boltzmann limit; van der Pauw measurement; Semiconductor; Nanoelectronics; Nanophysics; Solid state physics; Technology and Engineering;

    Sammanfattning : Kryoelektronik är av allt större intresse inom många tillämpningar, exempelvis för utveckling av kvantdatorer. Detta arbete vill därför undersöka de effekter kryogeniska temperaturer (under 10 K) har på halvledarkomponenter och deras elektriska egenskaper. Särskilt intressant är effekten på subthreshold swing (SS). LÄS MER
