    Sammanfattning : How did fossil-fuelled technology find its way to Egypt on its way to global dominance? This thesis presents a socioecological history of energy technologies in agrarian production in pre-colonial Egypt (1820s – 76). It situates them in the nineteenth century, understood as the beginning of the epoch of the Capitalocene; and in Egypt’s case, this is simultaneously part of the rise of Britain’s fossil empire.

  3. 2. Extracellular Matrix Remodelling-Proteoglycan and collagen turnover in arthritis

    Författare :Anette Bjärdahlen; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arthritis; collagen; cartilage; myofibroblasts; pannus; proteoglycan; Skeleton; muscle system; rheumatology locomotion; reumatologi; Skelett; muskelsystem;

    Sammanfattning : Rheumatoid arthritis is a chronic, inflammatory and systemic disease characterised by joint destruction and pannus formation. To enlarge the understanding how pannus and granulation tissue are formed two animal models were used; one using cartilage wrapped in cotton and implanted into a rat air pouch (AP) and one where mBSA induced arthritis (AIA) was performed.

  4. 3. Computational Studies of Cellulose-based Materials

    Författare :Jiu Pang; Igor Zozoulenko; Alexandar Mehandzhiyski; Sergei Popov; Maria Sammalkorpi; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Cellulose is a remarkable organic biopolymer and sustainable raw material existing in nature. Over the past several decades, the study of cellulose materials has attracted significant attention in chemistry, physics, biomedicine, and engineering fields. LÄS MER

  5. 4. Amphiphilic Polymers as Additives in Biomedical Polyurethanes. Surface Properties and Morphology

    Författare :Maria Kober; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymer micelles; phase separation; migration; poly ethylene oxide ; surface enrichment; morphology; polyurethane; additives; Surface modification; amphiphilic polymers; polymer blends; Polymer technology; biopolymers; Polymerteknik;

    Sammanfattning : The aim of this work was to achieve surface modification of two biomedical polyurethanes and one poly(urethane urea) through the addition of small amounts of amphiphilic copolymers in solution. The matrix polymers used were the poly(ether urethane)s Pellethane 2363-80AE (P80) and 2363-75D (P75) and a poly(ether urethane urea) similar to Biomer (PUUR). LÄS MER

  7. 5. Breaking the chains : A technological and industrial transformation beyond papermaking: Technology management of incumbents

    Författare :Michael Novotny; Staffan Laestadius; Lars Coenen; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technological and industrial transformation; development block; incumbents; pulp and paper industries; wood-based biorefinery; diverging innovations of non-assembled products; Teknologisk och industriell omvandling; utvecklingsblock; etablerade företag och industrier; massa- och pappersindustrin; vedbaserade bioraffinaderier; divergerande innovationer av icke-sammansatta produkter.; Industriell ekonomi och organisation; Industrial Engineering and Management;

    Sammanfattning : In recent years, the necessity and opportunity for transforming pulp and paper mills into integrative units for large-scale output of biochemicals, biomaterials, and biofuels have come up in discussions of industrial renewal in the Northern hemisphere (mainly in Canada, Sweden and Finland). This transformation is related to technology shifts as well as changing business models based on new bioproducts due to profoundly new market conditions. LÄS MER
