  1. 1. Sailing or Sinking Together : Container Shipping in Digital Platform Capitalism

    Författare :Tom Chabosseau; Ilkka Henrik Mäkinen; Patrik Aspers; René Taudal Poulsen; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Digital Platform Capitalism; Container Shipping; Logistics; Field Theory; Text Mining; Sociologi; Sociology;

    Sammanfattning : This thesis addresses the classical research problem of collaboration among competing actors in the context of digital platform capitalism. This study investigates how ocean carriers attempted, and sometimes managed, to set standards, exchange data, and jointly develop supply chain management platforms despite the alleged risks of doing so.

  3. 2. Modeling internal deformation of salt structures targeted for radioactive waste disposal

    Författare :Zurab Chemia; Hemin Koyi; Harro Schmeling; Ian Alsop; Uppsala universitet; []
    Nyckelord :salt; diapir; anhydrite; deformation; entrainment; numerical modeling; rheology; sinking; Gorleben;

    Sammanfattning : This thesis uses results of systematic numerical models to argue that externally inactive salt structures, which are potential targets for radioactive waste disposal, might be internally active due to the presence of dense layers or blocks within a salt layer.The three papers that support this thesis use the Gorleben salt diapir (NW Germany), which was targeted as a future final repository for high-grade radioactive waste, as a general guideline.

  4. 3. Mechanical Characterisation of Coatings and Composites-Depth-Sensing Indentation and Finite Element Modelling

    Författare :Zhi-Hui Xu; KTH; []
    Nyckelord :dept-sensing indentation; nanoindentation; finite element method; atomic force microscope;

    Sammanfattning : In the past two decades depth-sensing indentation has becomea widely used technique to measure the mechanical properties ofmaterials. This technique is particularly suitable for thecharacterisation of materials at sub-micro or nano scale thoughthere is a tendency to extend its application to the micro ormacro scale. LÄS MER

  5. 4. När fysik blir lärområde i förskolan

    Författare :Jonna Larsson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emergent science; physics; children; learning; preschool; begynnande naturvetenskap; fysik; barn; lärande; förskola;

    Sammanfattning : This dissertation includes four separate empirical studies, and is directed towards what happens when physics becomes a learning area in preschool. It is about children and preschool teachers exploring and working with physical phenomena such as friction, sound, floating and sinking. LÄS MER

  7. 5. Compositional variability of settling organic particles in non-tidal coastal and shelf enviroments

    Författare :Mona Petersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; vertical flux; particulate matter; amino acids; Skagerrak; Limfjorden; Geovetenskap; Earth sciences; Geovetenskap; naturgeografi; Physical Geography;

    Sammanfattning : The coupling between the composition of settling organic particles and near-bed dynamics was studied in non-tidal coastal and shelf environments. Field investigations were made in Skagerrak and Limfjorden between 1990 and 1995. LÄS MER
