  1. 1. Structural studies of enzymes regulating bacterial life style and cell wall biogenesis

    Författare :Ming Wei Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Bacteria can adapt to different biotic and abiotic environments by changing their life style, switching between sessile or motile, free-living or community-bound, virulent or dormant states. Each bacterium also faces the challenges of maintaining a protective barrier while growing, replicating and responding to environmental changes. LÄS MER

    Författare :Chen Wei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; river sediments; sample analysis; metals;

    Sammanfattning : Metal transport, speciation and toxicity were studied in urban runoff and receiving urban river systems. Sediments were recognised as an important environmental compartment for metals. LÄS MER

  5. 4. Glass Ionomer Cements with Improved Bioactive and Antibacterial Properties

    Författare :Song Chen; Håkan Engqvist; Wei Xia; Jie Zhou; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterial; glass ionomer cement; bioactivity; hydroxyapatite; monetite; calcium silicate;

    Sammanfattning : Dental restorative cements are placed in a harsh oral environment where they are subjected to thermal shock, chemical degradation, and repeating masticatory force. The ideal restorative dental cements should have superior mechanical properties, chemical stability, aesthetic, good handling properties, biocompatibility, antibacterial properties, and preferably bioactivity.

  7. 5. Cyber-Physical Engineering of Distributed Automation Systems in Energy Domain

    Författare :Chen-Wei Yang; Valeriy Vyatkin; Evgeny Osipov; Nirmal Nair; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : The main focus of this thesis is in the domain of Energy Systems, specifically in the engi-neering of modern Smart Grid (SG) automation systems. The SG has been categorizedas a Cyber-Physical System (CPS), a complex system which exhibits tight integration between the cyber and the physical processes and their interactions in a networked envi-ronment.
