  5. 4. Evaluation of suitable nursery areas for penaeid shrimps in shallow water systems in southern Mozambique

    Författare :Daniela de Abreu; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tropics; Southeast Africa; Shallow water; Estuaries; Nursery ground value; Decapods; Penaeidae; Carbon and nitrogen isotopes; Diet; Acetyl cholinesterase; Butyryl cholinesterase; Metals;

    Sammanfattning : Tropical shallow water habitats such as estuaries, mangrove forests and seagrass beds are important nursery areas for juveniles of many commercially important species including penaeid shrimp. Penaeids are one of the most important fishery resources worldwide, and in Mozambique they are the basis of a profitable commercial fishery, landing hundreds of tons per year. LÄS MER

  7. 5. A Biotechnology Perspective on Silicon Nanowire FETs for Biosensor Applications

    Författare :Nima Jokilaakso; Amelie Eriksson Karlström; Christer Wingren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The study of silicon nanowire-FET-based electronic biosensor applications is an emerging scientific field. These biosensors have the benefit of being theoretically extremely sensitive and reports of down to femtomolar (fM) levels of biomolecule detection have been reported. LÄS MER
