  1. 1. Protection of Biomolecules by Antioxidants - Mechanisms and Applications

    Författare :Carl Grey; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dG; antioxidants; mass spectrometry; Analytical chemistry; Analytisk kemi; Food and drink technology; Livsmedelsteknik; Bioteknik; Biotechnology; DNA; Oxidation; Protein; Fenton reaction;

    Sammanfattning : Reactive oxygen species (ROS) consisting of various oxygen-based free radicals as well as other reactive non-radical species produced in O2-related metabolism or through other processes are involved in the oxidation of such vital biomolecules as DNA, proteins and lipids. The types of oxidation represented here are known to cause many different diseases and disorders in human beings, such as cancer, Alzheimer's disease and ageing. LÄS MER

  3. 2. A radical view of haemoglobin - protein engineering and characterisation

    Författare :Marie Grey; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; His-Gln tagging; protein purification; blood substitutes; radical scavenging; superoxide dismutase; E. coli; diglobin; Haemoglobin; protein engineering; aqueous two-phase systems; hydrophobic interaction chromatography;

    Sammanfattning : In recent years shortages of donated blood have become a growing problem for health care systems world-wide. Blood substitutes based on human haemoglobin (Hb) could potentially ameliorate this situation. However, clinical trials have indicated problems due to e.g. LÄS MER

  4. 3. Defining moments : a cultural biography of Jane Eyre

    Författare :Philip Grey; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Literature; identity; production; representation; regulation; consumption; circuit of culture; discourse; publishing; biography; canonization; adaptation; education; moral panic; criticism; Charlotte Brontë; Victorian literature; National Curriculum; Litteraturvetenskap; Literature; Litteraturvetenskap; Literature; litteraturvetenskap;

    Sammanfattning : This thesis examines the ways in which various practices, such as novel-writing, publishing, book-reviewing, reading for pleasure, adaptation and studying English literature, have produced Jane Eyre’s complex cultural profile. The organizing principle of the study is Paul du Gay, Stuart Hall et al’s ‘circuit of culture’, which identifies five key processes or ‘moments’ as being productive of the meanings that a cultural artefact or text comes to possess.

  5. 4. Grey-box Identification of Distributed Parameter Systems

    Författare :Yi Liu; Elling W. Jacobsen; Denis Dochain; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; grey-box modeling; grey-box identification; model reduction; PDE; chromatography; bifurcation; moving mesh methods; orthogonal collocation on moving finite elements; OCMFE; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : This thesis considers the problem of making dynamic models for industrial processes by combining physical modelling with experimental data. The focus is on distributed parameter systems, that is, systems for which the model structure involves partial differential equations (PDE). Distributed parameter systems are important in many applications, e. LÄS MER

  7. 5. "Please Mind the Grey Digital Divide" : An Analysis of Digital Public Policies in Light of the Welfare State (Sweden and Greece)

    Författare :Sofia Alexopoulou; Joachim Åström; Martin Karlsson; Elin Wihlborg; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; grey digital divide; welfare regimes; digital public policies; digital technologies; older people;

    Sammanfattning : This thesis examines the grey digital divide and digital policies in the divergent welfare regimes of Sweden and Greece. The grey digital divide is a serious problem not only for the individual but also for society. The grey digital divide signifies the inability of older people to utilize digital technology. LÄS MER
