  1. 1. Försvarets elasticitet i princip och praktik. Arméns teknikförnyelse under mellankrigstiden 

    Författare :Petter Wulf; Hans Weinberger; Arne Kaijser; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; teknikförnyelse; försvarsmaterialsförsörjning; elasticitet; anpassning; Historiska studier av teknik; vetenskap och miljö; History of Science; Technology and Environment;

    Sammanfattning : Det är ett grundläggande krav på dagens svenska försvar att det ska kunna anpassa sig till nya förhållanden. Här finns en parallell med mellankrigstiden (1919-1939). LÄS MER

  3. 2. Studies in Local Public Transport Demand

    Författare :Johan Holmgren; Jan Owen Jansson; Lars Westin; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public transport; Demand; Elasticity; Price; Service; Time series; Panel data; Kollektivtrafik; Efterfrågan; Elasticitet; Pris; Trafikutbud; Inkomst; Bilinnehav; Tidsserieanalys; Paneldata; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of four papers where the overall purpose is to contribute to the understanding of how local public transport demand is affected by different factors. An underlying theme running trough the thesis is the two-way relationship between public transport demand and the service level caused by the fact that capacity and quality are joint products.

  4. 3. Lung volumes and lung mechanics in anesthetized children

    Författare :Adalbjörn Thorsteinsson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sulfur hexafluoride; Anaesthesiology; lung volumes; lung compliance; Anesthesia: pediatric; functional residual capacity; intensive care; Anestesiologi; ventilation inhomogeneity; intensivvård; airway closure;

    Sammanfattning : The thesis was intended to fill gaps in the knowledge regarding the normal development of lung volumes and lung mechanics in children, from young infancy to the mid-teens. In particular, data were previously lacking regarding pre-school children. The studies were done during anesthesia and muscle relaxation. LÄS MER

  5. 4. Numerical simulation of non-Newtonian fluids flow over surfaces

    Författare :Kazem Bazesefidpar; Outi Tammisola; Luca Brandt; Shahriar Afkhami; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic wetting; viscoelasticity; non-Newtonian fluids; contact- angle hysteresis; droplet spreading; self-propelled jumping; dynamisk vätning; viskoelasticitet; icke-Newtonska vätskor; kontaktlinjehysteres; dropparnas spridning på ytor; spontan hoppning av droppar från ytor; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Wetting of surfaces by droplets of non-Newtonian fluids is important for various industrial and natural processes such as coating and cleaning of surfaces and inkjet printing, to name a few. Viscoelastic fluids are compounds of a very small amount of polymers and solvent. LÄS MER

  7. 5. Hierarchical Assembly Investigations and Multiscale Characterization of Protein-based Materials : Insights from Whey Protein Nanofibrils and Recombinant Spider Silk Microspheres

    Författare :Eirini Ornithopoulou; My Hedhammar; Thomas Crouzier; Christina Divne; Tim Melander Bowden; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hierarchical Assembly; Protein-based materials; Whey Protein Nanofibrils; β-Lactoglobulin; Recombinant Spider Silk; Microspheres; Biomedical Applications; Surface Biofunctionalization; Hierarkisk montering; Proteinbaserade material; Vassleprotein nanofibriller; β-Laktoglobulin; Rekombinant spindelsilke Mikrosfärer; Biomedicinska tillämpningar; Ytbiokonjugering; Biotechnology; Bioteknologi;

    Sammanfattning : Protein-based materials, with their unique properties of combining high strength, while maintaining elasticity, and their inherent biocompatibility, hold immense potential for various applications. In order to harness these properties, we need to understand and control how protein building blocks come together to form hierarchically structured materials. LÄS MER
