1. 16. Light-Emitting Electrochemical Transistors

   Författare :Jiang Liu; Magnus Berggren; Isak Engquist; Qibing Pei; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Since the discovery of conductive polymers in 1977, the implementation of organic conjugated materials in electronic applications has been of great interest in both industry and academia. The goal of organic electronics is to realize large-area, inexpensive and mechanically-flexible electronic applications. LÄS MER

3. 17. Fibre flow mechanisms

   Författare :Roger Bergström; Ulf Björkman; Bo Norman; Mark Martinez; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre flow; floc; shear; compression; fibre network; stress chain; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Sammanfattning : The flow behaviour, and primarily the floc-floc interaction, of pulp paper suspensions have been studied visually. Analogy models based on these observations have been developed as well as the identification of important parameters of floc break-up in low shear rate flow fields. LÄS MER

4. 18. The interdependence of plastic behaviour and final properties of steel wire, analysed by the finite element method

   Författare :Henrik Överstam; Magnus Jarl; Sven-Erik Lundberg; Chunhui Luo; Örebro universitet; []
   Nyckelord :Technology; FEM; defects; steel wire; wire drawing; rolling; forging; Teknikvetenskap; TECHNOLOGY; TEKNIKVETENSKAP; Maskinteknik; Mechanical Engineering;

   Sammanfattning : The finite element method (FEM) has been used in order to study the interdependence of plastic behaviour and final properties in steel wire. Three processes metal forming have been studied: billet forging, wire rod rolling, and cold drawing. LÄS MER

5. 19. (Un)bearable freedom : Exploring the becoming of the artist in education, work and family life

   Författare :Sofia Lindström; Erling Bjurström; Marita Flisbäck; Stephanie Taylor; Linköpings universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cultural work; visual artists; subjectivity; discourse analysis; narrative analysis; Konstnärligt arbete; bildkonstnärer; subjektivitet; diskursanalys; narrativ analys;

   Sammanfattning : The aim of this dissertation is to explore and understand three important social contexts for the becoming of an artistic subjectivity: education, work and family life. The empirical data consist of interview material with alumni from the Royal Institute of Art in Stockholm, staff of the institute, and a survey material from the Swedish National Artists Organization (KRO/KIF).

7. 20. Studies on Thiol-Disulfide Oxidoreductases in Bacillus subtilis

   Författare :Mirja Carlsson Möller; Molekylär cellbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Microbiology; bacteriology; bacterial sporulation; endospore; thioredoxin; Thiol-disulfide oxidoreductase;

   Sammanfattning : Bacillus subtilis is a model organism for endospore-forming gram-positive bacteria. Endospores are formed in response to nutrient starvation. They can resist harsh environments and last for long periods of time. Once nutrients again become available, the endospore can germinate and the vegetative life cycle be resumed. LÄS MER
