  1. 1. Shaping Macroporous Ceramics : templated synthesis, X-ray tomography and permeability

    Författare :Linnéa Andersson; Lennart Bergström; Ludwig Gauckler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alumina; ceramic; CO2 capture; colloidal processing; expandable microspheres; gel casting; layer-by-layer; macroporosity; near-net shape; non-destructive evaluation; permeability; porosity; sacrificial templating; X-ray computed tomography; Chemistry; Kemi; Materials Chemistry; materialkemi;

    Sammanfattning : Macroporous ceramic materials have found widespread technological application ranging from particulate filters in diesel engines, tissue engineering scaffolds, and as support materials in carbon capture processes. This thesis demonstrates how the pore space of macroporous alumina can be manipulated, analysed in three-dimensions (3D) using visualisation techniques, and functionalised with a CO2-adsorbing material.

  3. 2. Shaping Risk Management in Banks

    Författare :Vikash Kumar Sinha; Mats Engwall; Håkan Kullvén; Torkel Strömsten; Marika Arena; Andrea Mennicken; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; internal audit; risk management; risk culture; Basel models; operational risk; liquidity risk; internrevision; riskhantering; riskkultur; Baselmodellerna; operativ risk; likviditetsrisk; Industriell ekonomi och organisation; Industrial Economics and Management; Business Studies; Företagsekonomi;

    Sammanfattning : The recent financial crisis of 2007-08 was a watershed moment in the history of banking. The unprecedented event led to severe scrutiny by standard setters and regulators on how the business of banking is run. As a result of this strict scrutiny, a wide variety of reforms aimed at the second line of defense (risk management) ensued globally. LÄS MER

  4. 3. Mechanical properties and microstructure of laser sintered and starch consolidated iron-based powders

    Författare :Yu Wang; Jens Bergström; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powder metallurgy; Laser sintering; Microstructure; Fatigue; Thermal fatigue; Wear; Starch consolidation; Rapid forming; Net shaping; Liquid phase sintering; Nitriding; High speed steels; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

    Sammanfattning : In powder metallurgy research field, Direct Metal Laser Sintering (DMLS) and Metal Powder Starch Consolidation (MPSC) are relatively new rapid forming techniques to fabricate complex and near net-shaped components. The working principles of DMLS are to melt and fuse metal powder layer by layer in computer controlled systems to pile up components like three dimensional printing. LÄS MER

  5. 4. The role of adjuvant-induced innate immune activation in shaping vaccine responses

    Författare :Elizabeth A Thompson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Adjuvants are components added to non-live vaccine formulations to enhance the effect of the vaccine by alerting the immune system to initiate a response against the vaccine. Powerful new adjuvants will be critical for the development of next generation vaccines to diseases such as tuberculosis, HIV-1/AIDS, malaria, and therapeutic cancer vaccines. LÄS MER

  7. 5. Genetic and epigenetic factors shaping the transcriptome in multiple sclerosis and its animal model

    Författare :Petra Bergman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Multiple Sclerosis (MS) is a chronic inflammatory and demyelinating disease of the central nervous system. Susceptibility to develop MS is determined by both genetic and environmental factors. The epigenome resides in the interface of genetic and environmental factors thereby shaping the transcriptome.
