  1. 1. Bridging the boundaries between D&T education and working life : A study of views on knowledge and skills in product development

    Författare :Helena Isaksson Persson; Inga-Britt Skogh; Robert Höghielm; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; upper secondary school education; design and product development; technology programme; repertory grid technique; artefacts; engineer; industrial designer; working life; gymnasium; produktutveckling; design; teknikprogrammet; utbildning; artefakter; yrkesliv; ingenjör; industridesigner; Teknikvetenskapens lärande och kommunikation; Education and Communication in the Technological Sciences;

    Sammanfattning : In Sweden upper secondary school education is organised in programmes. One of these programmes is the Technology programme that covers five orientations, one of which is Design and Product Development. LÄS MER

  3. 2. High-resolution measurement of the ¹⁶O(γ,pn) reaction

    Författare :Lennart Isaksson; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pn ; E_gamma = 67-76 MeV; resolved states; cross-sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:1996:Isaksson; 16O gamma; Photonuclear reaction;

    Sammanfattning : The 16O(gamma,pn) reaction has been measured with a resolution high enough to resolve individual low-lying states in the residual 14N nucleus. The relative population of the states provides detailed information about the quantum numbers of the proton-neutron pairs on which photons are absorbed. LÄS MER

  4. 3. Methods of Measuring Radioactivity in the Environment

    Författare :Mats Isaksson; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radioactivity; soil sampling; depth distribution; nuclear weapons fallout; Chernobyl; sewage sludge; deposition; Ekologi; Fysicumarkivet A:1997:Isaksson; Ecology; Kärnfysik; Nuclear physics; Cs-137;

    Sammanfattning : In this thesis a variety of sampling methods have been utilised to assess the amount of deposited activity, mainly of Cs-137, from the Chernobyl accident and from the nuclear weapons tests. Starting with the Chernobyl accident in 1986 sampling of air and rain was used to determine the composition and amount of radioactive debris from this accident, brought to southern Sweden by the weather systems.

  5. 4. Initiation of Autoimmunity in Experimental Autoimmune Encephalomyelitis

    Författare :Magnus Isaksson; Anna Lobell; Olle Kämpe; William Agace; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autoimmunity; Cytokines; Dendritic cells; DNA vaccination; EAE; Innate immunity; T helper cells; Toll-like receptors; Type I interferons; Molekylär medicin; Molecular Medicine;

    Sammanfattning : The events that trigger an autoimmune disease remain largely unknown. To study these events animal models are necessary because symptoms of autoimmune diseases are preceded by a long asymptomatic period in humans. LÄS MER

  7. 5. Investigating genetic factors behind the decline of a threatened plant species – Tephroseris integrifolia (Asteraceae)

    Författare :Kerstin Isaksson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantitative genetics.; AFLP; local genetic variation; relict populations; fragmentation; small populations; sporophytic self-incompatibility; extinction; threatened species; Inbreeding depression; population structure;

    Sammanfattning : Landscape change in Europe has caused the decline of many grassland species. Tephroseris integrifolia (Asteraceae) is one species which has declined rapidly in Sweden since the 19th century. LÄS MER
