  1. 1. The role of freshwater phytoplankton in the global carbon cycle

    Författare :Fabian Engel; Gesa A. Weyhenmeyer; Don Pierson; Katrin Attermeyer; John A. Downing; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; carbon dioxide; lake; river; global limnology; spatial scale; carbon budget;

    Sammanfattning : Water flowing through the landscape transports chemical substances including carbon. Along the way from upland soils to the ocean, carbon is transformed from organic carbon into inorganic carbon and vice versa. One such carbon transformation process is the uptake of carbon dioxide (CO2) from the water phase by phytoplankton. LÄS MER

  3. 2. Protein-Based Adhesives for Particleboards

    Författare :Sara Khosravi; Mats Johansson; A. A Broekhuis; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Sammanfattning : The main objective of this study was to elucidate the possibilities to use wheat gluten (WG) as a binder for particleboards, as well as soy protein isolate (SPI). The focus was on the effect of the adhesive formulation and the processing conditions, while the press parameters were kept constant. LÄS MER

  4. 3. Magnetic bead-based isolation of biological therapeutic modalities

    Författare :Nils A. Brechmann; Véronique Chotteau; Nigel Titchener-Hooker; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic bead separation; Magnetic beads; Protein A; Protein G; Negative cell isolation; Monoclonal antibody; induced pluripotent stem cells; human mesenchymal stem cells; Allogenic cell therapy; Biomanufacturing; cell clarification; Biotechnology; Bioteknologi;

    Sammanfattning : Biopharmaceutical modalities, such as monoclonal antibodies or the less established cell therapies, are nowadays very important for the treatment of severe or incurable diseases. The manufacturing of such modalities is complex and costly, including the downstream processing, which is highly essential to ensure the safety and quality of the product. LÄS MER

  5. 4. Color Centers in Semiconductors for Quantum Applications : A High-Throughput Search of Point Defects in SiC

    Författare :Joel Davidsson; Igor A. Abrikosov; Rickard Armiento; Viktor Ivády; Giulia Galli; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; point defects; color centers; high-throughput; photoluminescence; zero phonon line; SiC;

    Sammanfattning : Point defects in semiconductors have been and will continue to be relevant for applications. Shallow defects realize transistors, which power the modern age of information, and in the not-too-distant future, deep-level defects could provide the foundation for a revolution in quantum information processing.

  7. 5. Study on the Function of Translation Initiation Factor IF1

    Författare :Victor Croitoru; Leif A. Isaksson; Kim Kusk Mortensen; Stockholms universitet; []
    Nyckelord :translation; initiation factor IF1; mutagenesis; A-site; RNA chaperone; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Initiation is the first step in protein biosynthesis representing a fundamental event in cell life which determines fidelity, efficiency and regulation of gene expression. In addition to the ribosome and mRNA, three protein factors IF1, IF2 and IF3 are involved in the initiation of translation in prokaryotes. LÄS MER
