    Abstract : In most of the industrialised world, the proportion of older and retired people in the population is continuously increasing. This will have budgetary implications for maintaining the welfare state, because the active working section of the population must fund the non-active and old population. READ MORE

  4. 2. Control of Alloy Composition and Evaluation of Macro Inclusions during Alloy Making

    Author : Yuichi Kanbe; Du Sichen; Leiv Kolbeinsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slag metal reaction; equilibrium; kinetics; largest inclusion; statistics of extreme values; electrolytic extraction; cross section; inclusion morphology; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : In order to obtain a good performance and predict the properties of alloys, it is necessary to control the contents of alloying elements and to evaluate a largest inclusion in the product. Thus, improved techniques for both control of alloy elements and evaluation of the large inclusion in products will enable us to provide better qualities of the final products. READ MORE

    Abstract : This doctoral thesis presents a modeling method fordemonstrating the behavior of inclusions and their surroundingmatrix during plastic deformation of steels.Inclusions are inescapable components of all steels. READ MORE

  6. 4. One-school-for-all As Practice – A Nexus Analysis of Everyday Digitalization Practices

    Author : Lars Almén; Sangeeta Bagga-Gupta; Cecilia Bjursell; Giulia Messina Dahlberg; Pia Lane; Jönköping University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; nexus analysis; digitalization; one-school-for-all; inclusion; identity;

    Abstract : The Government of Sweden formulated a strategy in 2017 to digitalize the entire Swedish educational system. The government summarizes this strategy through three focus areas: (i) all parts of the school system shall have equitable digital competence, (ii) all parts of the school system shall have equal access to and usage of digital tools, and (iii) research and follow-up of the possibilities of digitalization shall be conducted.

  7. 5. Formation of non-metallic inclusions and the possibility of their removal during ingot casting

    Author : Lars Ragnarsson; Sichen Du; Carlo Mapelli; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ingot casting; tool steel; inclusion; runner; refractory; erosion; casting powder; cold model; argon shroud; reoxidation; oxygen measurement; CFD; PIV; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The present study was carried out to investigate the formation and evolution of non-metallic inclusions during ingot casting. Emphasize have been on understanding the types of inclusions formed and developed through the casting process and on the development of already existing inclusions carried over from the ladle during casting.
