2. 21. Simulation of diffusional processes in alloys : techniques and applications

   Author : Henrik Strandlund; John Ågren; John Morral; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; Kirkendall effect; Phase transformations; Random walk; Solute drag; Interfacial mobility; Other materials science; Övrig teknisk materialvetenskap;

   Abstract : This thesis concerns computer simulation of diffusional processes in alloys. The main focus is on the development of simulation techniques for diffusion in single-phase domains, but also diffusion controlled phase-transformations and interfacial processes are discussed. READ MORE

4. 22. The Establishment of Semi-Presidential Regimes : A Mixed Methods Approach to How and Why

   Author : Jenny Åberg; Thomas Sedelius; Joachim Åström; Thomas Denk; Petra Schleiter; Högskolan Dalarna; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Semi-presidentialism; regime type; constitutional choice; diffusion; legacies; transitional bargaining; Intercultural Studies; Interkulturella studier;

   Abstract : One of the crucial constitutional choices made in a democratizing or recently independent state is the structure of executive-legislative relations that forms into a parliamentary, presidential, or semi-presidential regime. Even so, only a few studies have sought the reasons for the establishment and least of all is known when it comes to the most recent of them: the semi-presidential one. READ MORE

5. 23. Social movements and social networks

   Author : Rickard Sandell; Peter Marsden; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; sociologi;

   Abstract : One consistent finding in research on social movement organizations is that people's participation as well as their involvement in the formation of these organizations is linked to their structural location in several social dimensions. Hence, understanding the premises for social movement organizations is ultimately a question of examining the structure of people's social networks. READ MORE

6. 24. Coagulation of Cellulose: from Ionic-Liquid Solution to Cellulose Nanostructure

   Author : Artur Hedlund; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wet Spinning; Cellulose; Ionic Liquids; Diffusion; Coagulation; Nonsolvent;

   Abstract : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. READ MORE

7. 25. Phase Phenomena in Polymer Networks : Empirical Studies on the Influence of Hydrophobicity, Charge Density and Crosslinks on Macroion-Induced Phase Transitions in Polyelectrolyte Gels

   Author : Martin Andersson; Per Hansson; Lennart Piculell; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gel; microgel; microsphere; polystyrenesulfonate; polyacrylate; polyacrylicacid; DoTAB; DoTAC; CTAB; CTAC; network; polyelectrolyte; complex salt; self assembly; phase behaviour; hysteresis; thermodynamic; core-shell; lysozyme; cytochrome c; microscopy; micromanipulator; elastomer; elastic; protein; surfactant; phase behaviour; sorting; PHARMACY; FARMACI; Physical chemistry; Fysikalisk kemi;

   Abstract : The thesis concerns polyelectrolyte gels in contact with oppositely charged proteins and surfactant micelles, and includes of four papers (I-IV). In paper I confocal Raman spectroscopy was introduced as a method to trace micelles and investigate the structure of gel-surfactant complexes, in phase separated gel spheres. READ MORE
