    Sammanfattning : Background Animal models can be used to mimic human conditions of psychopathology, and also as pre-clinical models to evaluate candidate drugs. With hormonal treatment it is possible to produce behavior in the rat which corresponds to the mental symptoms of pre-menstrual syndrome (PMS), and pre-menstrual dysphoric disorder (PMDD). LÄS MER

    Sammanfattning : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

  4. 3. Psychophysiological and Performance Aspects on Motion Sickness

    Författare :Joakim Dahlman; Torbjörn Falkmer; Torbjörn Ledin; John Golding; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Sammanfattning : Motion sickness is not an illness, but rather a natural autonomic response to an unfamiliar or specific stimulus. The bodily responses to motion sickness are highly individual and contextually dependent, making them difficult to predict. The initial autonomic responses are similar to the ones demonstrated when under stress. LÄS MER

    Sammanfattning : During the so-called early modern time, i.e. from 1500 to 1800, Sweden as well as other European states went through fundamental changes. The central power increased its influence and control over society and its people. LÄS MER

  7. 5. Aesthetic Flexibility : Modularity of Visual Form in Product Portfolios and Branded Products

    Författare :Torbjörn Andersson; Johan Ölvander; Anders Warell; Stefan Holmlid; Monika Hestad; Linköpings universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aesthetic flexibility; industrial design; product modularity; brand extension; product portfolio development; carry-over; face-lift;

    Sammanfattning : The increase in competition amongst companies that produce complex or large product portfolios has created a need to utilise modularity strategies not only to flexibly manage technical complexity in a costeffective manner but also for visual appearance. This research aims to understand how the visual appearance of products is affected by modular product development strategies. LÄS MER
