    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognitive linguistics; cognitive tools; language; English; sense development; meaning extension; thought; metaphors; metonymies; scaffoldings; entrenchment; technology; electricity; steam engines; motor vehicles; roads; ways; Languages and linguistics; Språkvetenskap; English; engelska; Engelska med didaktiskt inriktning;

    Sammanfattning : In this thesis, the relationship between technological innovation and the development of language and thought is analysed. For this purpose, three different fields of technology are investigated: 1) the steam engine, 2) electricity, and 3) motor vehicles, roads and ways. LÄS MER

  3. 2. Bracing of steel bridges during construction; theory, full-scale tests and simulations

    Författare :Hassan Mehri; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bracing; steel-concrete composite; steel; bridge; test; construction; laboratory; experiment; experimental; theory;

    Sammanfattning : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.

  4. 3. Surface Properties of Antibodies and their Complexes with Antigens Studied by LLPC

    Författare :Christer Wingren; Institutionen för immunteknologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ligand-binding.; surface properties; isomerism; conformational changes; antibody; specificity; two-phase partitioning; antigen-binding sites; Biochemistry; Metabolism; Biokemi; metabolism;

    Sammanfattning : The main objective of this thesis was to gain further insight into the relationship between the exposed surfaces and the functional properties of antibodies and their complexes with antigens in solution. To study this relationship, a new technique, liquid-liquid partition chromatography (LLPC) in aqueous two-phase systems, was developed further with respect to sensitivity, selectivity and reproducibility.
