21. Free software to open hardware: Critical theory on the frontiers of hacking
Sammanfattning : Starting from the experiences of hackers developing free software and open hardware, this thesis addresses some key and recurrent themes in the field of Science and Technology Studies (STS). It poses the question: how are technologies conceptualised, constructed and used in ways that render some aspects of them transparent, while leaving others opaque? This question is complicated by the fact that what is visible and transparent to some will remain opaque to others, depending on the level of technical expertise commanded. LÄS MER
22. The use of Fenton chemistry for reducing the refining energy during TMP production : the effect of free ferrous and free or chelated ferric ions
Sammanfattning : The potential of using acid hydrogen peroxide under Fenton conditions to lowerthe electrical energy consumed during the production of Black spruce (Piceamariana) thermomechanical pulp (TMP) was investigated in pilot scale. Thechemical system, which consisted of ferrous sulphate, hydrogen peroxide andoptionally an enhancer (such as a chelating agent), was evaluated as an inter-stagetreatment. LÄS MER
23. Metal-Free Catalysis for Efficient Synthesis
Sammanfattning : The strength of efficient metal-free catalysis will be examined in this thesis. Efforts towards more sustainable processes will be demonstrated through implementation of strategies that meet several of the 12 principles of Green Chemistry. LÄS MER
24. Is it the gluten-free diet that matters the most? : Food, gender and celiac disease
Sammanfattning : Background: The only treatment for celiac disease consists of excluding gluten. Gluten is a protein complex found in wheat, rye, and barley, which are cereals commonly used in bread, pasta, pizza, etc. LÄS MER
25. Free fatty acids and insulin hypersecretion studied in human islets
Sammanfattning : Free fatty acid (FFA) levels are increased in many obese subjects. High FFA levels stimulate the pancreatic beta-cells but have negative long-term effects. In obese children with high FFA levels circulating insulin concentration is high early in life but decline with age precipitating the development of type 2 diabetes mellitus (T2DM). LÄS MER
