  1. 16. Characterization of White Layers induced by Hard Turning of AISI 52100 Steel

    Författare :Seyed Hosseini; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; white layer; hard turning; IR-pyrometer; nano-sized grains; martensite; cutting temperature; bainite; cubic boron nitride; residual stress; retained austenite; cutting forces;

    Sammanfattning : Hard turning is a machining process applied to metallic materials with hardness above 45 HRC. The process offers high production flexibility and sustainable manufacturing since it allows performing both rough and finishing machining of complex geometries in one single setup. LÄS MER

  3. 17. On Institutional Demands in Banking and the Exchange of Hard and Soft Accounting Information

    Författare :Magnus Norberg; Fredrik Nilsson; Linda Wedlin; Mikael Wendschlag; Katarina Kaarbøe; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Banking; Institutional demands; Regulatory initiatives; Exchange; Accounting information; Hard information; Soft information; Financial regulation; KRITA; MiFID II; Financial robo-advising; Transactions; Relationship; Firms; Digitalisation; Tension; Business Studies; Företagsekonomi;

    Sammanfattning : The overarching purpose of the thesis is to explore how institutional demands influence banks, which has been a core issue in banking research. This has become even more critical since the financial crisis of 2007–2009. LÄS MER

  4. 18. Multicomponent Alloying for Improved Hard Coatings

    Författare :Rikard Forsén; Magnus Odén; Naureen Ghafoor; Mats Johansson; Jochen Schneider; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Coatings are vital to protect and to increase the productivity of cutting tools in high speed and dry cutting applications. During the cutting operation the temperature may exceed 1000 ºC it is therefore necessary that the coatings withstand high temperatures. LÄS MER

  5. 19. Gene expression during hard tissue formation

    Författare :Catharina Ellerström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :bone; dentin; mRNA; fibrillar collagens; osteonectin; fibronectin; development; rat;

    Sammanfattning : The purpose of this thesis was to study the formation of the extracellular matrix (ECM) of bone and dentin during development. Molecular techniques, such as in situ hybridization and RT-PCR, were used to investigate the occurrence of specific gene products in formative cells. LÄS MER

  7. 20. 'Soft' Questions in a 'Hard' Industry? : Sociotechnical Problems of the Mining Industry

    Författare :Joel Lööw; Jan Johansson; Margareta Oudhuis; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arbetsvetenskap; Human Work Sciences;

    Sammanfattning : The workplaces of mining industry fail to attract the skills and competences that the industry needs for maintaining its production and, in particular, tackling its future challenges. Some of the challenges that face the mining industry are technical and call for technical solutions: deeper and poorer ore deposits, greater environmental requirements, and lower ore prices, for example.
