  1. 31. Associative Multicomponent Polymers in Bulk and at Interfaces

    Författare :Fredrik Joabsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymer adsorption; polymer self-diffusion; polymer-surfactant interactions; phase behaviour; ethyl hydroxyethyl cellulose; hydrophobically modified polymers; capillary-induced phase separation; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The solution and interfacial properties of an associative water-soluble cellulose derivative, ethyl(hydroxyethyl)cellulose (EHEC) have been investigated. Main themes have been to study the effect of hydrophobic modification of the polymer (HM-EHEC) and the interactions with surfactants, both in bulk and at interfaces. LÄS MER

  3. 32. Modelling and analysis of multiphysical interactions in hydropower rotor systems

    Författare :Martin Karlsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : In this thesis the objective is to develop rotordynamical models of hydropower units, where coupling between mechanical, electromagnetic and fluid dynamical system systems is of certain interest. Both fluid-rotor and electromechanical interactions are known to change the system coefficients of the rotor system, which affects eigenfrequencies, damping, stability and response. LÄS MER

  4. 33. Integration and creative experiences after a merger of two organizations within the Social Insurance Service : A longitudinal group perspective

    Författare :Ingrid Dackert; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Experience sampling; Repertory grid; Team climate; Innovation; Creativity; Organizational climate; Merger; Organizational culture; Psychology; Psykologi;

    Sammanfattning : Mergers of organizations are a widespread phenomenon in the public as well as in the private sector. The individual and the organizational outcomes are dependent on the success of the integration process. During the integration after a merger, a cross-fertilization of ideas, working methods etc. LÄS MER

  5. 34. Polymer Gels and their Interactions with Ionic Surfactants

    Författare :Olof Rosén; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Polymer-Surfactant Interactions; Modified Polymers; Binding Isotherm; Polymer Gels; Swelling Isotherm; Fysikalisk kemi;

    Sammanfattning : The response on chemically crosslinked gels and polymer solutions on the addition of ionic surfactants and/or addition of salt at different temperatures have been studied. All polymers studied are water soluble and slightly hydrophobic or hydrophobically modified. LÄS MER

  7. 35. The Inherent Complexity of Agglomeration : Essays on the self-organization of urban economies

    Författare :Joakim Wernberg; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Complex adaptive system CAS ; Complexity; Self-organization; Agglomeration economies; Knowledge spillovers; Information processing; Local interactions; Cities; Urban economies; Urban Scaling; Intra-urban scaling;

    Sammanfattning : This doctoral thesis combines complexity science and economic geography in order to explore bottom-up, self-organizing principles within urban economies, in particular in relation to the flow of information and knowledge between people. The thesis consists of a kappa that covers the general theoretical framework and four papers. LÄS MER
