    Detta är en avhandling från Center for Chemistry and Chemical Engineering

    Författare :Malin Mejàre; Lunds universitet.; Lund University.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cadmium; metal quantification; fusion tag; metal affinity tag; phage display; peptide library; metal tolerance; metal resistance; metal accumulation; bioremediation; transgenic plant; tobacco; potato; protein purification; immobilised metal affinity chromatography; metal affinity precipitation; metal detection; protein stabilisation; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry; metal ion;

    Sammanfattning : Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. LÄS MER

  5. 5. Aspects of Adapting Data Collection to Intrusion Detection

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ulf Larson; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data collection; data reduction; intrusion detection; Manifestation extraction; log analysis;

    Sammanfattning : The focus of this thesis is on data collection and in particular data collection for intrusion detection purposes. Data collection is the first, and possibly most important activity in the overall intrusion detection process. The result of the detection can never be better than the data on which the detection is based. LÄS MER
