  1. 1. Applications of active materials

    Författare :Erik Edqvist; Greger Thornell; Bengt Lundberg; Edwin Jäger; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficient; microsystem; resonating cantilevers; microactuators; P VDF-TrFE ; surface mounting assembly; multi layers; flexible printed circuit board; conveyer; three legged; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : Energy efficiency is a vital key component when designing and miniaturizing self sustained microsystems. The smaller the system, the smaller is the possibility to store enough stored energy for a long and continuous operational time. LÄS MER

  3. 2. The world household : Georg Borgström and the postwar population-resource crisis

    Författare :Björn Ola Linnér; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental history; natural resources; population growth; conservation; natural resource policy; environmental ideology; Georg Borgström; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : This dissertation deals with how the agenda of environmental issues was set in the early postwar years. Natural resources were placed high on the agenda of international politics, the scientific community and the media. LÄS MER

  4. 3. An Assessment Framework for Managing Corporate Sustainable Manufacturing

    Författare :Ilaria Giovanna Barletta; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; key performance indicators; sustainable manufacturing; life cycle thinking; energy efficiency; technology assessment; sustainability management; environmental sustainability;

    Sammanfattning : This research aims to support the manufacturing industry in the endeavour of achieving the seventeen sustainable development goals by 2030, with “sustainable production” (the 12th goal) being the key one it should achieve. The output of this research is synthesised into a framework comprising assessment methods and tools which translate both economic and environmental sustainability factors into information for a specific set of company management decisions.

  5. 4. Numerical and experimental study of performance of a hydraulic motor

    Författare :Leon Dahlén; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic fluid; hydrostatic transmission; hydraulic motor; Engineering mechanics; Teknisk mekanik; Maskinelement;

    Sammanfattning : The aim of this study was to develop an understanding of the fluid properties that influence the efficiency of hydraulic systems in a steady-state, especially components in hydrostatic transmission systems under different running conditions. The aim has also been to investigate and model the sources of losses in hydraulic machines, in order to estimate the losses, taking fluid properties into account. LÄS MER

  7. 5. Effects of commercial hatchery processing on behaviour and welfare of laying hens

    Författare :Louise Hedlund; Per Jensen; Charlotta Berg; Bas Rodenburg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Around the world, more than 76.7 million tons of eggs are consumed every year. To meet this demand, billions of laying hen chicks are produced under highly industrial circum-stances. These chicks are hatched in commercial hatcheries for laying hens in a presumably stressful environment, which might affect their welfare and production later in life. LÄS MER
