SYN-TES INTERDISCIPLINARY RESEARCH ON COLOUR AND LIGHT

Konferensbidrag (refereegranskat)abstract
- Colour and light have largely been considered as belonging to two different fields of knowledge, having disparate theoretical, terminological and methodological traditions. This creates a ground for misunderstandings and obstructs a fruitful interdisciplinary and interprofessional collaboration. A survey over international research literature from 2006 -2011 shows that there has been only little research on the spatial interaction between colour and light, but that the interest for this area has recently increased. The interdisciplinary Nordic research project SYN-TES: Human colour and light synthesis. Towards a coherent field of knowledge was carried out during 2010-11. Colour and light experts from Nordic universities and companies investigated different aspects of the spatial interaction between colour and light and its importance for human beings. This paper deals with the general learnings from the process. Specific results are presented in other papers at this conference.

Algebra för alla
- 1997. - 1
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Bakom titeln Algebra för alla ligger tanken att alla lärare som arbetar med matematik i grundskola och gymnasieskola ska ha glädje av innehållet och målet att alla elever ska möta matematikens generaliserande kraft. Syftet med materialet är att avdramatisera arbetet med skolalgebra samt att uppmärksamma och stimulera möjligheterna att arbeta med olika uttrycksformer. I boken ingår ett stort antal elevaktiviteter och studieuppgifter för lärare samt litteraturförslag.

Matematikkundervisning
- 2013
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Denna boken är skriven av en grupp erfarna norska och svenska lärarutbildare i matematik. Boken bygger på utprövad erfarenhet - såväl egen som andras - och på aktuell, relevant forskning i matematikdidaktik. Texten väver samman matematik och matematikdidaktik, det vill säga ämnet som det undervisas i och frågor om hur ämnet kan läras och undervisas. Boken innehåller det som är absolut viktigast att få med sig i den grundläggande lärarutbildningen i matmatik.

Influence of cobalt substitution on the magnetic properties of Fe5PB2

Tidskriftsartikel (refereegranskat)abstract
- In this study the effects of cobalt substitutions in Fe5PB2 have been studied. An increased cobalt content reduces the magnetic exchange interactions. This has been concluded from a large, linear decrease in both the Curie temperature as well as the saturated magnetic moment. At high cobalt concentrations, cobalt prefers to order at the M(2) position in the crystal structure. A tunable Curie transition like this shows some prerequisites for magnetic cooling applications.The substitutional effects of cobalt in (Fe1–xCox)5PB2 have been studied with respect to crystalline structure and chemical order with X-ray diffraction and Mössbauer spectroscopy. The magnetic properties have been determined from magnetic measurements, and density functional theory calculations have been performed for the magnetic properties of both the end compounds, as well as the chemically disordered intermediate compounds. The crystal structure of (Fe1–xCox)5PB2 is tetragonal (space group I4/mcm) with two different metal sites, with a preference for cobalt atoms in the M(2) position (4c) at higher cobalt contents. The substitution also affects the magnetic properties with a decrease of the Curie temperature (TC) with increasing cobalt content, from 622 to 152 K for Fe5PB2 and (Fe0.3Co0.7)5PB2, respectively. Thus, the Curie temperature is dependent on composition, and it is possible to tune TC to a temperature near room temperature, which is one prerequisite for magnetic cooling materials.
