   Författare :Karin Due; Sylvia Benckert; Britt-Marie Berge; Svein Sjøberg; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; physics education; science education; gender; group discussions; upper secondary school; sociocultural theory; discourse analysis; images of physics; Fysikdidaktik; naturvetenskapernas didaktik; genus; gruppdiskussioner; gymnasieskolan; sociokulturell teori; diskursanalys; föreställningar om fysik; lärande; Subject didactics; Ämnesdidaktik;

   Sammanfattning : This thesis investigates how students in upper secondary school solve problems and discuss physics in small groups. The study examines how gender, knowledge in physics and the image of the subject physics are constructed in the students’ conversation and how these processes are related to each other. LÄS MER

4. 3. Contributions to the Use of Statistical Methods for Improving Continuous Production

   Författare :Francesca Capaci; Erik Vanhatalo; Bjarne Bergquist; Murat Kulahci; Johan Carlson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process industry; Continuous process; Statistical process control; Design of experiments; Process improvements; Simulation tool; Engineering process control; Kvalitetsteknik; Quality Technology Management;

   Sammanfattning : Complexity of production processes, high computing capabilities, and massive datasets characterize today’s manufacturing environments, such as those of continuous andbatch production industries. Continuous production has spread gradually acrossdifferent industries, covering a significant part of today’s production. LÄS MER

5. 4. Phase chemistry in process models for cement clinker and lime production

   Författare :Bodil Hökfors; Rainer Backman; Bo Björkman; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process modelling; phase chemistry; cement clinker; lime; sustainability; CO2; energy;

   Sammanfattning : The goal of the thesis is to evaluate if developed phase chemical process models for cement clinker and lime production processes are reliable to use as predictive tools in understanding the changes when introducing sustainability measures.The thesis describes the development of process simulation models in the application of sustainability measures as well as the evaluation of these models.

7. 5. Partial CO2 capture to facilitate cost-efficient deployment of carbon capture and storage in process industries - Deliberations on process design, heat integration, and carbon allocation

   Författare :Max Biermann; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon allocation; Partial CO2 capture; process industry; techno-economic assessment; CCS; heat recovery; amine absorption;

   Sammanfattning : Climate change requires that all energy-related sectors reduce drastically their greenhouse gas (GHG) emissions, at a global rate of 1–2 GtCO2 per year, starting now. Process industries, such as the iron and steel, cement, petrochemical, and oil-refining industries, are inherently carbon-intensive, and carbon capture and storage (CCS) is one of the few options available to achieve the required deep reductions in carbon dioxide (CO2) emissions.
