2. 1. Ontological Ordering : Achieving Audience in Internet Practice

   Author : Emma Dahlin; Alexa Robertson; Trond Lundemo; Charles Ess; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; audience; ontological ordering; empirical philosophy; enactment; ontology; Science and Technology Studies; Media and Communication Studies; medie- och kommunikationsvetenskap;

   Abstract : Against the backdrop of changing technological conditions of the contemporary media landscape, new questions arise regarding how audience can be can problematized and theorized. This dissertation seeks to shift the focus from conventional assumptions of what audience is to an empirical exploration of the specificities of the process through which audience is achieved in practice.

   Abstract : Information and communication technologies (ICT) have experienced a technological convergence. Laptops, tablets and smartphones integrate previously distinct artefacts and communication protocols within information systems, personal computers and telephony. READ MORE

5. 3. Characterisation of mechanical and thermal properties of tungsten for high power spallation target applications

   Author : Jemila Habainy; Materialteknik; []
   Keywords : Utmattning; Termisk diffusivitet; Volfram; Spallation; Strålningseffekter; ESS; Oxidation; Mekaniska egenskaper; Mechanical Properties; Thermal diffusivity; Tungsten; ESS; Spallation target; Irradiation effects; Fatigue; Oxidation;

   Abstract : The European Spallation Source (ESS), which is currently under construction in Lund, will use pure tungsten as the spallation neutron target. The tungsten will be irradiated by a 2 GeV proton beam, pulsed at a repetition rate of 14 Hz. READ MORE

6. 4. Evolution of Plants : a mathematical perspective

   Author : Magnus Lindh; Åke Brännström; Jacob Johansson; Mats G Larson; Lennart Persson; Claus Rüffler; Umeå universitet; []

   Abstract : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. READ MORE

7. 5. A Fast Pixelated Thermal-Neutron Detector

   Author : Emil Rofors; Kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SoNDe; thermal-neutron detector; GS20 scintillator; Li-glass; H12700A MAPMT; position-dependent response; alpha-particle; proton; deuteron; neutron; ESS; SKADI;

   Abstract : This thesis presents the study of a position-sensitive scintillation-based detector called the Solid-State Neutron Detector (SoNDe). SoNDe is being developed for cold- and thermal-neutron detection at the small-angle neutron scattering (SANS) instrument SKADI at the European Spallation Source (ESS), currently under construction in Lund, Sweden.
