  1. 1. The control of growth and metabolism in Caenorhabditis elegans

    Författare :Josefin Friberg; Simon Tuck; Cathy Savage-Dunn; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TGFβ; insulin; collagen; p70 S6K; metabolism; growth; dauer; Caenorhabditis elegans; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : The control of growth is a poorly understood aspect of animal development. This thesis focuses on body size regulation in Caenorhabditis elegans, and in particular, how worms grow to a certain size. In C. elegans, a key regulator of size is the TGFβ homologue DBL-1. LÄS MER

  3. 2. The plasticity of aging and survival : a role for the thioredoxin system in Caenorhabditis elegans

    Författare :Juan Carlos Fierro-González; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Thioredoxin and related systems regulate many biological processes in diverse species. In mammals, in addition to protecting against oxidative damage, they also play key roles as regulators of transcription factors, signaling cascades and immune responses. LÄS MER

  4. 3. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets

    Författare :Ragni Fjellgaard Mikalsen; Vidar Frette; Bjarne C. Hagen; Ulrich Krause; Anne Steen-Hansen; Ulrich Krause; Nieves Fernandez-Anez; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel storage safety; Industrial fire; Biofuels; Smoldering; Extinguishment; Fire suppression; Fire growth; Fire spread; Heat transfer; Nonlinear dynamics; Complex systems; Combustion; Biomass energy; Synchronization; Oscillations; EMRIS;

    Sammanfattning : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. LÄS MER

  5. 4. Discovering and targeting the mechanisms that govern age-related decline

    Författare :Xin-Xuan Lin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aging is recognized as a major risk factor for many diseases. Thus, the identification of a means to target aging would bear great potential to improve human health and quality of life. LÄS MER

  7. 5. Langzeitemissionsverhalten von Deponien für Siedlungsabfälle in den neuen Bundesländern

    Författare :Lale Andreas; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Sammanfattning : Langzeitemissionsverhalten von Deponien für Siedlungsabfälle in den neuen BundesländernZusammenfassungZiel der vorliegenden Arbeit war die Beschreibung des Langzeitverhaltens von DDR-Depo­nien unter besonderer Berücksichtigung der Emissionen auf dem Sickerwasserpfad.Die Beschreibung umfaßte die untersuchten Deponiestandorte, die Deponierungspraxis in der DDR, cha­rak­teristische Eigenschaften der abgelager­ten Abfälle sowie der nach mehrjähriger Lage­rungs­zeit ausgekofferten Altabfallproben, die Sickerwasseremissionen der Deponie Döbeln-Hohenlauft, das Auslaugverhalten der Altabfälle in Mehrfachelutionsversuchen und die Sickerwasser- und Gas­emis­­sionen der Deponiesimulationsversuche.
