  2. 1. Flow-oriented studies for environmental management by local authorities : experiences from a regional substance flow analysis

    Author : Annica Lindqvist-Östblom; Linköpings universitet; []
    Keywords : flow-oriented studies; material flow analysis; substance flow analysis; interpretation; local authorities; regional authorities; environmental management; cadmium; sewage;

    Abstract : This thesis focuses on the issue of how to perform flow-oriented studies in order to become more useful for and adapted to local/regional authorities. Compared to traditional environmental monitoring and measurement of the state of the environment, flow-oriented studies are an attempt to broaden the approach to environmental concerns. READ MORE

  4. 2. Choreographing Flow : A Study in Concrete Deposition

    Author : Helena Westerlind; Hélèna Frichot; Marcelyn Gow; KTH; []
    Keywords : HUMANIORA; HUMANITIES; Architectural Technology; Arkitekturteknik;

    Abstract : The traditional use of concrete in architecture is fundamentally conditioned by the inverse relationship that exists between material and formwork. When poured into a mold, a homogenous mixture takes the shape of its container. More detailed adjustment of the structure of concrete, however, is not possible. READ MORE

  5. 3. Managing the flows? Furthering a socio-material flow methodology for industrial ecology

    Author : Mathias Lindkvist; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; industrial ecology; actor-network-theory ANT ; methodology; action nets; socio-material; field studies; conceptualisation; material flow; review; life cycle assessment LCA ;

    Abstract : This dissertation defends the thesis that application of the socio-material methodology that I present can assist environmentally more effective decision-making. The methodology provides a recipe for a systematic and accurate understanding of how human actions determine environmental impacts via material (tangible) flows. READ MORE

  6. 4. Decarbonising the Stainless Steelmaking through Alloy Solutions

    Author : Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. READ MORE

  7. 5. Effect of swirling blade on flow pattern in nozzle for up-hill teeming

    Author : Line Hallgren; Pär Jönsson; Jonas Alexis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirling flow; up-hill teeming; nozzle; casting; fluid flow; modelling; CFD; LDA.; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The fluid flow in the mold during up-hill teeming is of great importance for the quality of the cast ingot and therefore the quality of the final steel products. At the early stage of the filling of an up-hill teeming mold, liquid steel enters, with high velocity, from the runner into the mold and the turbulence on the meniscus could lead to entrainment of mold flux.
