  1. 1. Barnlitteraturens tekniklandskap : En didaktisk vandring från Nils Holgersson till Pettson och Findus

    Författare :Cecilia Axell; Jonas Hallström; Jan-Erik Hagberg; Lena Kåreland; Linköpings universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technology education; children’s literature; views of technology; views of nature; views of future; Teknikdidaktik; barnlitteratur; tekniksyn; natursyn; framtidssyn;

    Sammanfattning : Syftet med denna studie är att utifrån ett didaktiskt perspektiv undersöka budskap om teknik i ett urval svenska skönlitterära barnböcker samt undersöka hur berättelsernas tekniksyner förhåller sig till deras natur- respektive framtidssyn. Analyserna grundar sig på sex svenska författares skönlitterära barnböcker: Selma Lagerlöf, Otto Witt, Elsa Beskow, Karl-Aage Schwartzkopf, Sven Wernström och Sven Nordqvist. LÄS MER

  3. 2. Synthesis of amino- and hydroxyl-substituted bridged bicyclic compounds and their application in asymmetric catalysis

    Sammanfattning : In this work, hydroxyl- and amino-substituted bridged bicyclic compounds based on bicyclo[2.2.1]heptane, bicyclo[2.2. LÄS MER

  4. 3. Functional collaboration between HLH transcription factors in B cell development

    Författare :Ramiro Gisler; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; E47; Early B cell Factor EBF ; Clinical genetics; Klinisk genetik; HLH proteins; transcription factors; gene expression; B cell development; transcription regulation;

    Sammanfattning : The cells in B cell development can be divided into several subgroups or fractions, e.g. early-pro-B-, pro-B, large-pre-B-, small-pre-B-, immature and mature B cells, where the stages reflect the maturity degree of the cells. LÄS MER

  5. 4. Complexation between hydrophobically modified polymers and amylose. Gelation and competition by surfactants

    Författare :Monica Egermayer; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; rheology; Physical chemistry; Fysikalisk kemi; inclusion complex; amylose; surfactant; ethyl hydroxyethyl cellulose; hydrophobically modified polymer; hydroxyethyl cellulose;

    Sammanfattning : Aqueous mixtures of hydrophobically modified polymers (HMP) with amylose have been investigated by rheology and 1H NMR. Amylose can cross-link HMP chains by forming single-helical inclusion complexes with the hydrophobic side chains of the HMP, leading to thermoreversible, elastic, and thixotropic gels at ambient temperatures.

  7. 5. Variational Methods in Combinatorial Optimization and Phylogeny Reconstruction

    Författare :Henrik Jönsson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; annealing; variational; mean-field; phylogeny; constraint satisfaction; combinatorial optimization; maximum likelihood; Physics; Fysik; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2001:Jönsson; Matematisk och allmän teoretisk fysik; thermodynamics;

    Sammanfattning : Algorithms based on the variational approach, as used in statistical physics, are developed. For constraint satisfaction problems a novel cost function, based on information-theoretic arguments, is introduced, and an algorithm similar to the mean-field annealing algorithm is proposed. LÄS MER
