  1. 1. Low smoke halogen-free materials for wire and cable applications

    Författare :Anna Lundgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flame retardant; calcium carbonate; calcium silicate; Casico; polyolefin; effervescence; intumescent structure; thermal degradation; silicone elastomer;

    Sammanfattning : Fire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start a fire and/or spread one. Traditionally, materials containing halogen have been used as primary insulation in low voltage power and telecommunication cables and most cables used today therefore contain halogen. LÄS MER

  3. 2. Mechanism of a polyolefin based effervescent flame retardant material

    Författare :Anna Lundgren; Chalmers tekniska högskola; []

    Sammanfattning : ABSTRACTFire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start and/or spread a fire. As a result of environmental and safety issues having to do with flame retardants based on halogens, much attention has lately been given to finding halogen free alternatives. LÄS MER

  4. 3. From Custom to Code : A Sociological Interpretation of the Making of Association Football

    Författare :Dominik Döllinger; Patrik Aspers; Tora Holmberg; Patrick McGovern; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; historical sociology; football; custom; culture; community; Sociologi; Sociology;

    Sammanfattning : The present study is a sociological interpretation of the emergence of modern football between 1733 and 1864. It focuses on the decades leading up to the foundation of the Football Association in 1863 and observes how folk football gradually develops into a new form which expresses itself in written codes, clubs and associations.

  5. 4. Simple haptics : Sketching perspectives for the design of haptic interactions

    Författare :Camille Moussette; Daniel Fällman; Bill Buxton; William Verplank; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; interaction design; haptics; haptic interactions; sketching; sketching in hardware; prototypes; prototyping; industrial design; human computer interaction; design research; research through desgin;

    Sammanfattning : Historically, haptics—all different aspects of the sense of touch and its study—has developed around very technical and scientific inquiries. Despite considerable haptic research advances and the obviousness of haptics in everyday life, this modality remains mostly foreign and unfamiliar to designers. LÄS MER
