    Sammanfattning : Today, there is an essential need for lightweight, energy-efficient, environmentally benign engineering systems, and this is the driving force behind the development of a wide range of structural and functional materials for energy generation, energy storage, propulsion, and transportation. These challenges have motivated the use of magnesium alloys for lightweight structural systems. LÄS MER

  3. 2. On the relation between paperboard properties and packaging performance

    Författare :Gustav Marin; Sören Östlund; Mikael Nygårds; Christer Korin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Paper-based materials, such as paperboard, are commonly used as packaging materials. Inaddition to the advantage that wood as a raw material is renewable, there are also many otherbenefits of paperboard. LÄS MER

  4. 3. Microsphere-based modeling of electro-active polymers

    Författare :Sara Thylander; Hållfasthetslära; []
    Nyckelord :;

    Sammanfattning : Elektroaktiva polymerers (EAPs) främsta egenskap är deras förmåga att kunna omvandla elektrisk energi till mekanisk energi (och vice versa). Den typ av EAPs som behandlas inom ramen för detta arbete kallas för dielektriska elastomerer och är en undergrupp av elektroniska elektroaktiva polymerer. LÄS MER

  5. 4. Impact of paperboard deformation and damage mechanisms on packaging performance

    Författare :Gustav Marin; Sören Östlund; Mikael Nygårds; Tomasz Garbowski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Paper-based materials, such as paperboard, are commonly used as packaging materials. In addition to the fact that paper is renewable, there are also many other benefits of paperboard. LÄS MER

  7. 5. Injury-Induced Signalling in Arterial Smooth Muscle Cells

    Författare :Sara Moses; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GAG; Clinical biology; Klinisk biologi; proteoglycan; osteopontin; ERK; MAPK; signalling; smooth muscle cell; injury;

    Sammanfattning : The vascular wall is an active, elastic and integrated organ made up of cellular and extracellular matrix (ECM) components. It is not a static organ; the components dynamically change and reorganize in response to physiological and pathological stimuli. Vascular injury induces a complex healing process, analogous to generalised wound healing. LÄS MER
