  1. 16. Improving selectivity in protein extraction by subtle interactions and environmental changes

    Författare :Sheryl Fernandes; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Difference Spectroscopy; Circular dichroism; Biotechnology; Bioteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Fluorescence spectroscopy; Metal ions; Cibacron blue; Polyvinylpyrrolidone; Polyethylene glycol; Triton X-114; His 6 tag; Cold-active ß-lactamase; Cold-active ß-galactosidase; Lactate dehydrogenase; Cutinase; Affinity Extraction; Conformational change; Partial Denaturation; Molecular interaction; Aqueous two-phase systems; Detergent foam;

    Sammanfattning : The challenges for efficient bioprocesses lie in developing and adapting further current technologies or in creating innovative separation technologies. The thesis is based on the studies on protein recovery from crude feedstocks by extraction in aqueous two-phase systems and detergent foam, respectively. LÄS MER

  3. 17. Change agency in (old) industrial regions : Shaping new futures

    Författare :Linda Stihl; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic Geography; Change Agency; Reproductive agency; Old industrial regions; Regional development; Ekonomisk geografi; Förändringsagens; Reproduktiv agens; Gamla industriregioner; Regional utveckling;

    Sammanfattning : The aim of the dissertation is to develop a better understanding of the role of local agency in the transformation of old industrial regions. Theoretically the dissertation builds on concepts which are important in the debate on regional development in old industrial regions such as path dependency, negative lock-ins, the role of institutions, and new path development, while exploring and unpacking the role of agency.

  4. 18. The potential of industrial hemp (Cannabis sativa L.) for biogas production

    Författare :Emma Kreuger; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; anaerobic digestion; bioenergy; Cannabis sativa L.; hemp; energy crops; biofuel; methane; transportation fuel; renewable energy;

    Sammanfattning : Biofuels are currently produced from agricultural crops, and an increasing use of crops for this application is expected in the EU in the years to come. The dominating crops cultivated in the EU for biofuel production today have a relatively large environmental impact. LÄS MER

  5. 19. Industrial Dynamics and Regional Structural Change : Geographical Perspectives on Economic Evolution

    Författare :Martin Henning; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; agglomeration externalities; industrial dynamics; Regional system; structural change; Sweden; industry life cycle; technology shift;

    Sammanfattning : This thesis investigates the process of economic transformation taking place in Sweden since the mid 1970s. Especially, it is concerned with how and why benefits that firms and industries draw from regional co-location with other actors (agglomeration externalities) vary over stages of economic transformation.

  7. 20. Towards membrane engineering as a tool in cell factory design: A case study on acetic acid tolerance in Saccharomyces cerevisiae

    Författare :Lina Lindahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; butanol; inhibitors; lipidomics; Key words: Lignocellulose; Zygosaccharomyces bailii; molecular dynamics simulations; membrane permeability; carbon-14 uptake; ethanol; robustness;

    Sammanfattning : The sustainable production of fuels, chemicals, and materials using renewable resources is a necessity if we are to reduce our ecological footprint and the rate of climate change. Lignocellulosic biomass, the major constituent of plant cell walls, is a renewable raw material with great potential due to its high abundance. LÄS MER
