   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sociology of technology; distance education; education; history of education; correspondence education; Learning Objects; standardization; actor-network theory; associations; translation; dispositif; tekniksociologi; distansutbildning; utbildning; korrespondensundervisning; lärobjekt; standardisering; aktörsnätverks teori; översättning; associering; dispositif; Technology and social change; Teknik och social förändring; Sociology; Sociologi; History of technology; Teknikhistoria; Education; Pedagogik; Informatics and systems science; Informatik och systemvetenskap;

   Abstract : This dissertation studies the social aspects of technology in distance education trough the lens of history – in the form of correspondence education – and a possible future – in the form of a project of technical standardization, Learning Objects. The studied cases form a reflexive tool that allows the present of distance education to be seen in perspective. READ MORE

4. 2. Video letters, mediation and (proper) distance : A qualitative study of international development communication in practice

   Author : Florencia Enghel; Miyase Christensen; Karin Wilkins; Robin Mansell; Karlstads universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; development communication; mediation; proper distance; international; video letters; Media and Communication Studies; Medie- och kommunikationsvetenskap;

   Abstract : This study scrutinizes the trajectory of an international development communication intervention aimed at mediating, rendering public and mobilizing processes of reconnection among estranged citizens across the former Yugoslavia. The intervention, which took place between 2000 and 2005 in the wider context of post-conflict international development assistance and peacebuilding operations in the region, was known as the Videoletters project.

5. 3. From torrefaction to gasification : Pilot scale studies for upgrading of biomass

   Author : Martin Strandberg; Anders Nordin; Linda Pommer; Jaap Kiel; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; biomass; pilot scale; continuous reactor; grindability; entrained flow gasification; degree of torrefaction; biomass powder;

   Abstract : Increasing the share of biomass, preferably by replacing fossil fuels, is one way to mitigate the present climate change. Fossil coal can be directly replaced by co-combustion of coal and biomass and fossil engine fuels (gasoline and diesel) could potentially partly be replaced by synthetic renewable fuels produced via entrained flow gasification of biomass.

6. 4. Large-scale Bioreactor Phenomena and Characteristics; Effects on E.coli fed batch fermentations on 30m3 scale

   Author : Gustav Silfversparre; KTH; []
   Keywords : Large-scale; E.coli; fed batch; concentration gradients; mixing;

   Abstract : Due to economical and practical limitations the fluiddynamics and mass transport properties are less optimal inlarge-scale bioreactors compared to lab-scale bioreactors. Incombination with the microbial reaction rates this creates amuch more dynamic environment for cells cultivated inlarge-scale bioreactors compared to lab-scale bioreactors. READ MORE

7. 5. Sustainability of the Swedish Sugar Sector : Assessment Tool Development and Case Study Appraisal

   Author : Barry Ness; LUCSUS; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; integrated assessment; DPSIR; scale; sugar beet; sugar; Sustainability science; sustainability assessment; proximity analysis; Scania; Sweden;

   Abstract : This thesis contributes to the development of tools and methods for assessing sustainability and applies them to an assessment of the Swedish sugar production system. The thesis’ aims are to compile an overview of the existing approaches for assessing sustainability, to suggest a method(s) for structuring and analyzing complex sustainability issues, and to appraise sustainability impacts from Swedish sugar production.
