  1. 1. Metal Affinity Peptides in Biotechnological Applications As tools in protein purification, protein stabilisation, metal quantification and metal tolerance of bacteria and plants

    Författare :Malin Mejàre; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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

  2. 2. Metal fate and sensitivity in the aquatic tropical vegetable Ipomoea aquatica

    Författare :Agneta Göthberg; Maria Greger; Hans Borg; M.N.V. Prasad; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; aquatic plants; vegetables; methyl mercury; metal accumulation; metal effects; thiol-rich peptides; Ipomoea aquatica; Plant physiology; Växtfysiologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The aquatic plant Ipomoea aquatica is a popular vegetable in Southeast Asia, often cultivated in nutrient rich and polluted waters. The overall aim of this thesis was to estimate potential risks for human health and reduced plant growth due to accumulation and toxicity of total-Hg, methyl-Hg, Cd and Pb. LÄS MER

  3. 3. Towards an Effective Virtual Sheet Metal Assembly Development Process Securing Geometrical Quality and Equipment Utilization

    Författare :Johan Segeborn; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot motion planning; geometrical quality; equipment utilization; robust design; Sheet metal assembly; tolerance analysis;

    Sammanfattning : Automobiles are an integral part of modern society and its way of life. In addition, automotive manufacturers are important institutions in society, summing the work of a vast array of sub suppliers, employing many. The margins are however moderate and competition is fierce. LÄS MER

  4. 4. Tolerance Analysis Framework for Cutting Tool Interface Design

    Författare :Soner Camuz; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variation simulation; reliability-based optimization; tolerance analysis; cutting tool interface design; geometry assurance;

    Sammanfattning : Tolerance analysis of cutting tool interface designs is a field with many opportunities for further development of existing methodologies. Cutting tool interface designs require multiple contacting surfaces, allocating the stress generated from the cutting forces, to avoid excessive deformation of the interface. LÄS MER

  5. 5. Fatigue of Metal Matrix Composites

    Författare :Magnus Levin; Chalmers University of Technology; []
    Nyckelord :mechanical properties; microstructures; manufacture; DMMC;

    Sammanfattning : This thesis treats the mechanical properties of discontinuously reinforced metal matrix composites, DMMCs, in general and their fatigue properties in particular. Methods of manufacture, microstructures and resulting mechanical properties of DMMCs are reviewed in the introductory part. LÄS MER
