  1. 1. Alveolar macrophages and lung surfactant in the defense against Cryptococcus neoformans

    Författare :Norma Teresa Gross; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :alveolar macrophages; Cryptococcus neoformans; lung surfactant;

    Sammanfattning : Cryptococcus neoformans causes disease mainly in immunosuppressed patients, especially those with AIDS, and on corticosteroids. The yeast is normally inhaled and the lung is the primary site of infection, where the alveolar macrophages (AM) provide a first line of host defense. LÄS MER

  3. 2. Phenotypic and Genotypic responses in the planktonic diatom Skeletonema marinoi - Effects of Natural Processes and Anthropogenic Stressors

    Författare :Susanna Gross; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diatoms; genotype; phenotype; resting cell; eutrophication; spring bloom; diversity; grazing; adaptation; phytoplankton; microalgae; Skeletonema;

    Sammanfattning : Diatoms are one of the most diverse and abundant phytoplankton taxa and are highly important as primary producers, accounting for nearly half of the marine primary production and constituting the base in the marine food web. Despite their high dispersal potential they are genetically diverse and display genetically structured populations. LÄS MER

  4. 3. Superdiffusive Spin Transport and Ultrafast Magnetization Dynamics : Femtosecond spin transport as the route to ultrafast spintronics

    Författare :Marco Battiato; Olle Eriksson; Hardy Gross; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ultrafast magnetisation dynamics; anomalous diffusion; femtosecond dynamics; magnetism; Materialvetenskap; Materials Science;

    Sammanfattning : The debate over the origin of the ultrafast demagnetization has been intensively active for the past 16 years. Several microscopic mechanisms have been proposed but none has managed so far to provide direct and incontrovertible evidences of their validity. LÄS MER

  5. 4. Magnesium ions stabilizing solid-state transition metal hydrides

    Författare :Helen Blomqvist; Karl J Gross; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi; Structural Chemistry; strukturkemi;

    Sammanfattning : This thesis is focused on hydrides containing first-row transition metal–hydrido complexes counterbalanced by magnesium. In particular, fundamental properties of the promising hydrogen storage material Mg2NiH4 have been studied. LÄS MER

  7. 5. Wireless Control of Modular Multilevel Converter Submodules

    Författare :Baris Ciftci; Hans-Peter Nee; Lennart Harnefors; Staffan Norrga; James Gross; Lars Kildehöj Rasmussen; Remus Teodorescu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G mobile communication; autonomous control; converter control; distributed control; electromagnetic interference; emerging technology; fault ride-through; modular multilevel converter MMC ; prototype; wireless control; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The modular multilevel converter (MMC) has extensively been used in high-voltage, high-power applications such as high-voltage dc transmission systems and flexible alternating current transmission systems. The control of MMC submodules is conventionally realized using wired communication systems. LÄS MER
