  1. 1. Welds in the lean duplex stainless steel LDX 2101 : effect of microstructure and weld oxides on corrosion properties

    Författare :Elin M. Westin; John Ågren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Duplex stainless steel; welding; weld metal; HAZ; nitrogen; manganese; austenite formation; phase balance; precipitates; pitting resistance; heat input; solidification; element loss; evaporation; deposition; weld oxides; discoloration; mechanical properties; thermo-mechanical simulation; Geeble; GTA; laser; LOM; SEM; EDS; TEM; Leco; EPMA; ferroxyl test; XPS; post weld cleaning; pickling; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Duplex stainless steels are a very attractive alternative to austenitic grades due to their higher strength and good corrosion performance. The austenitic grades can often be welded autogenously, while the duplex grades normally require addition of filler metal. LÄS MER

  3. 2. Microstructure and properties of welds in the lean duplex stainless steel LDX 2101

    Författare :Elin M. Westin; John Ågren; Hannu Hänninen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Duplex stainless steel; welding; HAZ; nitrogen; manganese; microstructure; austenite formation; phase balance; precipitates; element distribution; segregation; depletion; solidification; pitting corrosion resistance; solidification; element loss; evaporation; deposition; weld oxide; thermo-mechanical simulation; thermodynamic modelling; EPMA; XPS; post-weld cleaning; pickling; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : Duplex stainless steels can be very attractive alternatives to austenitic grades due to their almost double strength at equal pitting corrosion resistance. When welding, the duplex alloys normally require addition of filler metal, while the commodity austenitic grades can often be welded autogenously. LÄS MER

  4. 3. Bone Morphogenetic Protein 4 regulates white, beige and brown adipose tissue

    Författare :Jenny M Hoffmann; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obesity; BMP4; Browning; WAT; BAT; insulin sensitivity;

    Sammanfattning : Obesity and its associated complications, including Type 2 diabetes, are increasing at an epidemic rate globally. Adipose tissue exerts different functions and is central in energy homeostasis, and it consists of white, beige or brown adipocytes. LÄS MER

  5. 4. Shaping sustainable food systems : Local participation in addressing global challenges

    Författare :Aniek Hebinck; Line Gordon; Joost M. Vervoort; Stephan Barthel; Moya Kneafsey; Stockholms universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; food systems; sustainability; food governance; transformative change; participatory processes; participation; civil society; niche level; food policy; urban food; urban agriculture; food poverty; imagined futures; foresight; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : The current unsustainable trajectory of food systems puts the social and ecological processes and functions on which human flourishing depends at risk. This last decade has seen, on one hand, continued insistence on transformative action and on the other, uncertainty and instability with respect to traditional, established institutions, such as the state.

  7. 5. Using and Managing Resources in Industrialized House-Building : Characterization of a Swedish Industrialized House-Building Company from a Resource-Based View

    Författare :Petri Uusitalo; Lars Stehn; Susanne Engström; Daniel M. Hall; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entreprenourial orientation; Dynamic capability; Path dependency; Technology transfer; Resource based-view; Industrailized house-building; Byggproduktion och teknik; Construction Management and Building Technology;

    Sammanfattning : Global reports stress the importance of developing the construction industry to address productivity related issues and challenges with urbanization. McKinsey conclude that the construction industry could be more efficient by how they manage and employ resources to address the low productivity. LÄS MER
