1. 21. Development of a test facility for experimental investigation of fluid-structure interaction

   Författare :Nikolaos Andrinopoulos; Torsten H Hansson; Anestis Kalfas; KTH; []
   Nyckelord :;

   Sammanfattning : Fluid-structure interaction phenomena are strongly related to the loading appearing on many energy converting components introducing limitations for improving their efficiency. The term “fluid-structure interaction” includes many phenomena with the “shock wave – boundary layer interaction” being one of the most important. LÄS MER

3. 22. Conjugated Polymers for Neural Interfaces : Prospects, possibilities and future challenges

   Författare :Maria Asplund; Hans von Holst; Olle Inganäs; Thomas Stieglitz; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neuroprosthetics; conjugated polymers; conducting polymers; PEDOT; functional electrical stimulation; neural electrodes; Medical engineering; Medicinsk teknik; Neuroscience; Neurovetenskap; Functional materials; Funktionella material;

   Sammanfattning : Within the field of neuroprosthetics the possibility to use implanted electrodes for communication with the nervous system is explored. Much effort is put into the material aspects of the electrode implant to increase charge injection capacity, suppress foreign body response and build micro sized electrode arrays allowing close contact with neurons.

4. 23. Novel oil resistant cellulosic materials

   Författare :Christian Aulin; Lars Wågberg; Derek Gray; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oleophobic; MFC; cellulose; oil resistant; contact angle; XPS; SEM; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Sammanfattning : The aim of this study has been to prepare and characterise oil resistant cellulosic materials, ranging from model surfaces to papers and aerogels. The cellulosic materials were made oil resistant by chemical and topographic modifications, based on surface energy, surface roughness and barrier approaches. LÄS MER

5. 24. En Meningsfull Historia? : Didaktiska perspektiv på historieförmedlande museiutställningar om migration och kulturmöten

   Författare :Cecilia Axelsson; Lars Olsson; Lena Fritzén; Carina Rönnqvist; Växjö universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; museums; exhibitions; history; mediation of history; education; learning; making meaning of; historical consciousness; Afrikafararna; Kongospår; gender; class; ethnicity; democratic values; migration; cultural encounters; democratic conception of education; History; Historia; Historia; History;

   Sammanfattning : This thesis concerns the mediation of history in a public arena in society, namely in historical exhibitions in museums. The foci of the thesis are exhibitions on migration history, cultural encounters, “Us” and “the Others”, and in particular how relations based on the principles of class, gender and ethnicity are mediated.

7. 25. Dominanser : En utveckling av den realistiska livsformsteorin

   Författare :Jonas Axelsson; Jan Ch Karlsson; Liselotte Jakobsen; Tuula Bergqvist; Margareta Oudhuis; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; everyday life; life mode; life mode analysis; life mode theory; work; love; structural dominance; ownership; critical realism; Other social sciences; Övrig samhällsvetenskap; Working Life Science; Arbetsvetenskap;

   Sammanfattning : The present dissertation develops a specific theory about everyday life called realist life mode theory. This theory is based on critical realism and consists of "work", "love" and "life mode" as central concepts. The background of the theory is the Danish life mode analysis developed by Thomas Højrup in the 1980:s. LÄS MER
