  1. 11. Skissandets mening - Undersökningar på arbetsplatsen

    Författare :Tobias Engberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; contiguity; metonomy; heuristic; realism; rhetoric; memory; contexture; sketching; architecture; workplace;

    Sammanfattning : How do architects, when facing an unfamiliar situation, proceed and go about their work? One view would argue that they apply some universal principle or model, that helps them handle the many contingencies of a situation. But architects themselves often claim, on the contrary, that their work grows out of the situation genuinely. LÄS MER

  3. 12. Aspects of DNA Strand Exchange: Recombination Proteins and Model System Studies

    Författare :Karolin Frykholm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA strand exchange; cationic liposome; Rad51; Site-Specific Linear Dichroism; RecA; molecular crowding;

    Sammanfattning : DNA recombination is of fundamental importance to all living cells; it is part of the DNA repair machinery and a means to generate genetic diversity. DNA strand exchange, the exchange of strands between homologous DNA molecules, is the central reaction of the recombination process. LÄS MER

  4. 13. Surface Modifications and Applications of Aqueous Silica Sols

    Författare :Peter Greenwood; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applications; Surface modification; aqueous; silica sol; silane; colloidal silica; titania;

    Sammanfattning : Methods of modifying the surface of the particles of colloidal silica were developed and the effects of surface modification on the properties of colloidal silica were studied.Gamma-glycidoxypropyltrimethoxysilane (GPTMS) readily reacts with water to yield a hydrolysed silane that reacts readily with the silica surface.

  5. 14. Unfolding the formative phase of gasified biomass in the European Union: The role of system builders in realising the potential of second-generation transportation fuels from biomass

    Författare :Hans Hellsmark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; technical change; second-generation transportation fuels; technology policy.; technological innovation systems; biomass gasification; system builders;

    Sammanfattning : In an era of climate change, the process of and time frame for fostering new industries with the capacity of being innovative and able to diffuse a wide range of renewable energy technologies on a large scale has become a pressing issue. In the midst of the creation of such industries are the system builders―without such actors, new technologies and industries would not emerge. LÄS MER

  7. 15. Process Integration Opportunities for Synthetic Natural Gas (SNG) Production by Thermal Gasification of Biomass

    Författare :Stefan Heyne; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass; synthetic natural gas; energy systems; process integration; renewable energy;

    Sammanfattning : Synthetic natural gas (SNG) from gasified biomass is one promising option to produce renewable transport fuels. This thesis presents a process integration study investigating thermal gasification of biomass for the production of SNG and identifies critical conversion steps for the overall process performance.
