  1. 31. Inflation and Instabilities of Hyperelastic Membranes

    Författare :Amit Patil; Anders Eriksson; Arne Nordmark; Peter Hansbo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membranes; Constrained inflation; Energy release rate; Adhesive contact condition; Limit point; Bifurcation point; Wrinkling; Tension field theory; Pressure induced instability.; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The applications of membranes are increasing rapidly in various fields of engineering and science. The geometric, material, force and contact non-linearities complicate their analysis, which increases the demand for computationally efficient methods and interpretation of counter-intuitive behaviours.

  3. 32. It's who you know and what you know : exploring the relationship between education and prejudice in adolescence

    Författare :Lena Werner; Mikael Hjerm; Ingemar Johansson Sevä; Maureen A. Eger; Pieter Bevelander; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; anti-immigrant attitudes; education; critical thinking; multicultural education; teacher qualification; intergroup contact theory; secondary transfer effects; friendship; Sociology; sociologi;

    Sammanfattning : Background: Previous studies have consistently identified an association between higher levels of education and lower levels of anti-immigrant sentiment, but the underlying reasons for this relationship remain unclear. Therefore, this research aims to help explain why education matters for attitudes toward immigrants. LÄS MER

  4. 33. On the phase behaviour of hydrogels : A theory of macroion-induced core/shell equilibrium

    Författare :Jonas Gernandt; Per Hansson; Göran Frenning; Renko de Vries; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polymer; polyelectrolyte; surfactant; thermodynamics; elasticity; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : Colloidal macroions are known to interact very strongly with oppositely charged polyionic hydrogels. Sometimes this results in a non-uniform distribution of the macroions within the gel, a phenomenon that is not fully understood. LÄS MER

  5. 34. Concept evaluation and contact problems in simple rotordynamical systems

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

    Sammanfattning : Rotating machines serves an important role in many different applications. Extensive research has been made, manly during the last century, in order to develop these systems and understand the dynamics. The theory of rotordynamics differs in many fundamental aspects from structural dynamics and is therefore usually treated as an own research area. LÄS MER

  7. 35. Knowing and the Art of IT Management. An inquiry into work practices in one-stop shops

    Författare :Sara Eriksén; Institutionen för informatik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; systems theory; Informatics; IT management; one-stop shops; public service; Knowing; work practice; Informatik; systemteori; Knowing;

    Sammanfattning : New information technology is developing faster than the models, metaphors and methods in use for conceptualizing the sharing and managing of information in organizations, in communities and in society in general. The way we utilize information technology today does not seem to succeed in supporting the everyday work practices through which organizations accomplish their work. LÄS MER
