  1. 1. Towards computational materials design and upscaling of alternative binder cemented carbides

    Författare :David Linder; Annika Borgenstam; John Ågren; Jonas Östby; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Increasing demands on economic, social and environmental sustainability throughout society is putting pressure on the development of new and improved materials for resource efficiency, improved component life-time and substitution of toxic or rare elements. For the cemented carbide industry, as a major provider of tools for e.g. LÄS MER

  2. 2. The biology of cognitive decline and reduced survival in Parkinson disease : prognostic factors in a population-based cohort

    Författare :David C Bäckström; Lars Forsgren; Jan Linder; Niklas Lenfeldt; Jan Aasly; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson disease; multiple system atrophy; progressive supranuclear palsy; natural history; cognitive impairment; dementia; predictors of mortality; cerebrospinal fluid biomarkers; prospective; population-based; Neurology; neurologi;

    Sammanfattning : Parkinson disease (PD) is a progressive neurodegenerative disease that affects about 1% of the population over 60 years. The cardinal symptoms are motor disabilities but cognitive decline is also common. About 50% of all persons with PD develop dementia within 10 years after disease onset. LÄS MER

  3. 3. Using a Social Semiotic Perspective to Inform the Teaching and Learning of Physics

    Författare :Tobias Fredlund; Cedric Linder; David Wolfe; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Social semiotics; semiotic resources; physics education research; interactive engagement; disciplinary affordance; disciplinary-relevant aspects; patterns of disciplinary-relevant aspects; the Variation Theory of Learning; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Sammanfattning : This thesis examines meaning-making in three different areas of undergraduate physics: the refraction of light; electric circuits; and, electric potential and electric potential energy. In order to do this, a social semiotic perspective was constituted for the thesis to facilitate the analysis of meaning-making in terms of the semiotic resources that are typically used in the teaching and learning of physics.

  4. 4. Learning Physics through Transduction : A Social Semiotic Approach

    Författare :Trevor Stanton Volkwyn; John Airey; Bor Gregorcic; Cedric Linder; David Brookes; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Introductory physics; transduction; interactive engagement; social semiotics; representational competence; probeware; mathematical tools; 1-D kinematics; coordinate systems; magnetic field; pedagogical affordance; disciplinary affordance; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Sammanfattning : This doctoral thesis details the introduction of the theoretical distinction between transformation and transduction to Physics Education Research. Transformation refers to the movement of meaning between semiotic resources within the same semiotic system (e.g. LÄS MER
