  1. 1. Where Gendered Spaces Bend : The Rubber Phenomenon in Northern Laos

    Författare :Anna-Klara Lindeborg; Aida Aragao - Lagergren; Susanne Stenbacka; Jonathan Rigg; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Laos; LuangNamtha; rubber; gender; HatNyao; everyday life; bend; transitions; paradoxical spaces; intersectionality; ethnography; Hmong; phenomenon; gender contract; intersectionality; border-region; division of labour; China; Social and Economic Geography; Kulturgeografi; Geography; Geografi;

    Sammanfattning : This thesis seeks to understand and explain gendered everyday life in the village of HatNyao in Northwestern Laos, specifically in relation to rubber cultivation, by using an ethnographic approach and methods. The ‘rubber boom’ is changing the landscape of Northern Laos, and in the process is reshaping gendered everyday life. LÄS MER

  3. 3. Magneto-sensitive rubber in the audible frequency range

    Författare :Peter Blom; Leif Kari; Luigi Bregant; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magneto-sensitivity; Rubber; Audible frequency range; Amplitude dependence; Vibration isolator; Fletcher-Gent effect; Stiffness; Acoustics; Akustik;

    Sammanfattning : The dynamic behaviour in the audible frequency range of magneto-sensitive (MS) rubber is the focus of this thesis consisting of five papers A-E. Paper A presents results drawn from experiments on samples subjected to different constant shear strains over varying frequencies and magnetic fields. LÄS MER

  4. 4. Modelling the viscoplastic properties of carbon black filled rubber : A finite strain material model suitable for Finite Element Analysis

    Författare :Rickard Österlöf; Leif Kari; Alan Muhr; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcing fillers; rubber; finite strain; viscoplastic; förstärkande fyllmedel; gummi; finita töjningar; viskoplastisk; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : An increased environmental awareness, legal demands and the large part of total costs attributable to fuel cost are all incentives for the automotive industry to reduce fuel consumption. The optimal driveline to enable this reduction depends on the operational conditions and the available infrastructure. LÄS MER

  5. 5. Finite Element Procedures in Modelling the Dynamic Properties of Rubber

    Författare :Anders K Olsson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; akustik; vibration and acoustic engineering; Materiallära; materialteknik; Mechanical engineering; hydraulics; vacuum technology; Material technology; dynamic; amplitude; frequency; Technological sciences; Teknik; FEM; rubber; vibrationer; vakuumteknik; Maskinteknik; hydraulik;

    Sammanfattning : Rubber is not only a non-linear elastic material, it is also dependent on strain rate, temperature and strain amplitude. The non-linear elastic property and the strain amplitude dependence give a non-linear dynamic behavior that is covered by the models suggested in this thesis. LÄS MER
