1. 26. Transformation phenomena in a super duplex stainless steel

   Författare :Anders Wilson; KTH; []
   Nyckelord :Duplex stainless steel; Microstructure; Phase transformations; Precipitates; Sigma phase; Kinetics; Thermodynamic calculation; Continuous cooling transformation diagram; Time temperature transformation diagram; Computer model.;

   Sammanfattning : Duplex stainless steels consist of about equal fractions offerrite and austenite and are attractive due to their highcorrosion resistance against pitting corrosion and stresscorrosion cracking. The pitting corrosion resistance can bedescribed by the PREN value which is defined asPREN=%Cr+3.3*%Mo+16*%N. LÄS MER

3. 27. The effect of dissolved hydrogen on spent nuclear fuel corrosion

   Författare :Patrik Fors; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; alpha-doped; Nuclear waste repository; Hydrogen; Solubility; Corrosion; UO2; MOX; Spent nuclear fuel; High burn-up; Groundwater;

   Sammanfattning : In case of a canister failure in a deep bedrock repository for nuclear fuel, the release of radiotoxic nuclides to the groundwater will depend on the chemical environment near the fuel surface.Due to the presence of large amounts of iron in the canister, hydrogen will be formed if the canister becomes groundwater flooded.

4. 28. Constructive Conflict in Classrooms and Beyond

   Författare :Elizabeth Olsson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; CARE framework; collaboration; cooperation; grounded theory; interpersonal conflict; participant observation; schools; transformation;

   Sammanfattning : Conflict has exercised the minds of scholars since the establishment of the academy. Yet, those studying conflict continue to struggle over what, precisely, it is, and how and why it occurs. LÄS MER

5. 29. Characterisation of Fuels and Fly Ashes from Co-Combustion of Biofuels and Waste Fuels in a Fluidised Bed Boiler. A Phosphorus and Alkali Perspective

   Författare :Anita Pettersson; Högskolan i Borås; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; phosphorus recovery; co-combustion; fluidised bed combustion; olivine; Biofuels; zeolites; fertiliser; extraction; refuse derived fuels; kaolin; alkali; sulphur; ash; municipal sewage sludge;

   Sammanfattning : In the efforts to create sustainable production of heat and power and to reduce the net CO2 emissions to the atmosphere, alternative fuels are today being utilised. These fuels are, for example, biofuels and waste derived fuels such as different residues from the agricultural sector and the pulp and paper industry, municipal sewage sludge and municipal sorted solid waste.

7. 30. Point of care microfluidic tool development for resource limited settings

   Författare :Indradumna Banerjee; Aman Russom; Luca Brandt; Gustaf Mårtensson; Jens Ducrée; KTH; []
   Nyckelord :Blood; control; cell separation; centrifugal microfluidics; diagnostics; elasto-inertial; hematocrit level; microfluidics; neonatal diagnostics; nucleic acid quantification; point of care; particle focusing; resource limited settings.; Bioteknologi; Biotechnology;

   Sammanfattning : The development of point of care diagnostics using recent advances in microfluidics have the potential to transform health care in several ways, especially in resource limited settings with limited access to advanced health care infrastructure. However, translating a point of care device to reality is often a challenging task because of the complexities involved in integrating a number of diverse engineering concepts into an easy to use, accurate and portable device.
