  1. 21. Surface Densification of Solid Wood : Paving the Way Towards Industrial Implementation

    Författare :Benedikt Neyses; Dick Sandberg; Alexander Pfriem; Luleå tekniska universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

    Sammanfattning : Surface densification of a piece of solid wood results in an increase in density and in hardness in the whole or a part of the densified material, and is one of the ways of improving the properties and value of low-density wood species. Despite efforts for many years, mass commercialisation of either bulk- or surface-densified wood products has not yet been achieved. LÄS MER

  3. 22. Coteaching chemical bonding with Upper secondary senior students : A way to refine teachers PCK

    Författare :Felix Schultze; Pernilla Nilsson; Zimmerman Nilsson Marie-Helene; Anna Vikström; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Coteaching; pedagogical content knowledge; pck; chemical bonding; representations; chemistry education; chemistry didactic;

    Sammanfattning : The aim of this study was to investigate how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers while teaching chemical bonding in a grade 10 Upper secondary class. The study has been conducted from a sociocultural perspective, especially Vygotsky’s zone of proximal development (ZPD) (Vygotsky, 1978). LÄS MER

  4. 23. Dark Matter in the Milky Way

    Författare :Axel Widmark; Joakim Edsjö; David Milstead; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dark matter; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Den här licenciatuppsatsen bygger på två vetenskapliga artiklar, varav den första är skriven som ensamförfattare och den andra är skriven tillsammans med Dr. Giacomo Monari. De är båda på temat mörk materia i Vintergatan.Den första artikeln handlar om mörk materia som fångas i solen. LÄS MER

  5. 24. Deactivation of commercial three-way catalysts: Experimental and theoretical studies

    Författare :Anna Fathali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; car exhaust; three-way catalyst TWC ; alumina; fuel-cut; palladium; ; hydrocarbon cracking; ceria; deactivation; oxygen storage capacity OSC ; rhodium; zirconia; sintering; monolith catalyst; catalysis;

    Sammanfattning : This PhD thesis is a summary of my work with thermal deactivated commercial three way catalysts (TWCs). An examination of catalytic properties, before and after accelerated aging was performed, such as light-off temperature, specific surface area (BET), noble metal dispersion and oxygen storage capacity was performed.

  7. 25. Forming future IT : the living lab way of user involvement

    Författare :Anna Ståhlbröst; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informatik; Informatics;

    Sammanfattning : This thesis addresses the process of user involvement in the development of information technology (IT) systems. The motive for this research is that there is still a need of more knowledge about how users can be involved in IT-development when the aim is to develop solutions that represent user needs. LÄS MER
