1. 11. Sustainable Aluminum and Iron Production

   Författare :Reza Beheshti; Emma Strömberg; Jafar Safarian; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Optimization; Black Dross; Salt removal; Steel flux agent; Waste processing; Greenhouse gases; Direct reduction; COMSOL Multiphysics®; Kemi; Chemistry;

   Sammanfattning : Aluminium recycling requires 95% less energy than primary production with no loss of quality. The Black Dross (BD) produced during secondary aluminium production contains high amounts of water-soluble compounds, therefore it is considered as a toxic waste. LÄS MER

3. 12. The economics of a silent pandemic - A health economic analysis of antibiotic resistance in Sweden

   Författare :Sofie Larsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health economics; Economic analysis; Antibiotic resistance; Cost-effectiveness analysis; Production loss; QALY;

   Sammanfattning : The overall aim of this thesis was to analyze the health economic consequences of antibiotic resistance in Sweden, and to assess the implications of methodological assumptions related to measuring health in health economic analysis. The thesis consists of four papers. LÄS MER

4. 13. Importance of bacterial maintenance respiration and baseline respiration for development of coastal hypoxia

   Författare :Kevin Vikström; Johan Wikner; Jan Karlsson; Josep M. Gasol; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Respiration; Estuarine; Allochthonous; Maintenance; primary production; bacterial production;

   Sammanfattning : Reduced oxygen concentrations and increasing hypoxic zones havebecome more common in the sea due to climate change andeutrophication. The main cause of oxygen loss in oxygenatedenvironments is respiration. LÄS MER

5. 14. Part Quality Prediction and Variation Reduction in Multistage Machining Processes Based on Skin Model Shapes

   Författare :Filmon Yacob; Daniel Semere; Sophie Gröger; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining simulation; model-based prediction; variation propagation; variation source identification; variation compensation; tolerance analysis; Octree; anomaly detection; quaternion; dual quaternion; Plücker coordinate.; Maskinbearbetningssimulering; modellbaseradförutsägelse; variationsspridning; variationskällidentifiering; variationskompensation; toleransanalys; Octree; dual quaternions; Plücker-koordinat.; Production Engineering; Industriell produktion;

   Sammanfattning : All manufacturing processes inevitably induce variations into manufactured parts that may result in nonconformance. Nonconforming parts incur costs due to the additional process required for rework or scrap loss. Hence, methodical efforts to reduce these variations are necessary for competitive manufacturing.

7. 15. Dietary fibre production from oat hulls

   Författare :Eva Schmitz; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oat hulls; Dietary fibre; Chemical composition; Bleaching; Pre-treatment; Enzyme synergy;

   Sammanfattning : The current threats of climate change connected to the unsustainable consumption of fossil resources paired with an increasing world population demands the exploration of alternative raw materials for the production of food, fuel and specialty chemicals. Agricultural waste streams present suitable sources due to their availability in large quantities at low costs without competing with current food production. LÄS MER
