  3. 2. Measures that matter : Facilitating literacy through targeted instruction and assistive technology

    Författare :Thomas Nordström; Idor Svensson; Stefan Gustafson; Rickard Carlsson; Dave Edyburn; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Targeted instruction; intervention; assistive technology; reading difficulties; Riktad undervisningsinsats; intervention; assisterande teknik; lässvårigheter; Psychology; Psykologi; Special Education; Specialpedagogik; Education; Pedagogik;

    Sammanfattning : The acquisition of reading skills is one of the most important academic outcomes, as reading enables the individual to acquire knowledge and to actively take part in society. Despite research and educational progress, not all students develop their reading skills to a level that meet academic or societal demands. LÄS MER

  4. 3. Materials for Magnetic Recording Applications

    Författare :Till Burkert; Olle Eriksson; Lars Nordström; Stefan Blügel; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; magnetic materials; magnetic anisotropy; saturation magnetization; magnetic data storage; superlattice; hydrogen; density functional theory; first-principles calculations; two-dimensional magnetism; FP-LMTO; EXAFS; MOKE; Fysik; Physics; Fysik;

    Sammanfattning : In the first part of this work, the influence of hydrogen on the structural and magnetic properties of Fe/V(001) superlattices was studied. The local structure of the vanadium-hydride layers was determined by extended x-ray absorption fine structure (EXAFS) measurements. LÄS MER

  5. 4. Multiphase models for freeze-thaw actions and mass transport in concrete hydraulic structures

    Författare :Daniel Eriksson; Anders Ansell; Richard Malm; Erik Nordström; Stefan Jacobsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Degradation; Hydraulic structures; Air-entrained concrete; Multiphase models; Multiphysics; Long-term moisture conditions; Freeze-thaw; Hysteresis; Absorption; Calcium leaching; Finite Element Method; Concrete Structures; Betongbyggnad;

    Sammanfattning : A crucial task for civil engineers is to make appropriate designs of new concrete structures and assessments of existing structures to ensure a long service life and sustainable use of the infrastructure. This doctoral thesis aims to increase the understanding of how advanced mathematical models can be used to describe phenomena and processes governing concrete degradation and thereby ultimately contribute to improving tools for design and assessments.

  7. 5. Using patient-derived cell models to investigate the role of misfolded SOD1 in ALS

    Författare :Elin Forsgren; Jonathan Gilthorpe; Stefan Marklund; Peter Andersen; Thomas Brännström; Ulrika Nordström; Séverine Boillée; Umeå universitet; []
    Nyckelord :ALS; SOD1; patient-derived models; induced pluripotent stem cells; motor neurons; astrocytes; 20S proteasome low oxygen tension; misfolded SOD1; Neurology; neurologi;

    Sammanfattning : Protein misfolding and aggregation underlie several neurodegenerative proteinopathies including amyotrophic lateral sclerosis (ALS). Superoxide dismutase 1 (SOD1) was the first gene found to be associated with familial ALS. LÄS MER
