  1. 1. Distributed vehicle testing : dynamic simulation for automotive winter testing

    Författare :Mikael Nybacka; Luleå University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Today, rather than provide parts similar to their competitors and rely on one or two automakers, successful automotive component suppliers focus heavily on innovation and collaboration with several manufacturers in a global market. In this thesis, an as-is scenario for automotive winter testing is presented. LÄS MER

  4. 3. Communication of life cycle assessment results : life cycle key performance indicators

    Författare :Helena Nydahl; Thomas Olofsson; Anders P. Åstrand; Staffan Andersson; Åsa Wahlström; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; Monetary Valuation; Climate Impact; Life Cycle Key Performance Indicators; Global Warming Potential; LCA-result communication; Interpretation of LCA-results; climate change; klimatförändringar;

    Sammanfattning : The global warming that we are on track for will result in a severe loss of natural capital leading to significant losses in economic capital when urban infrastructure is destroyed, agricultural productivity declines and poverty spread among other disasters. Climate change due to emissions does not only affect the polluter, the hazardous effects becomes evident on a global level. LÄS MER

  5. 4. Experimental Evolution of Life-history : Testing the Evolutionary Theories of Ageing

    Författare :Hwei-yen Chen; Alexei Maklakov; Tracey Chapman; Uppsala universitet; []
    Nyckelord :senescence; ageing; longevity; mortality; experimental evolution; Caenorhabditis remanei; Biologi; Biology;

    Sammanfattning : Ageing reduces fitness, but how ageing evolves is still unclear. Evolutionary theory of ageing hinges on the fundamental principal that the force of natural selection declines with age. LÄS MER

  7. 5. Fatigue in individuals with multiple sclerosis : lived experiences and perceived impact in daily life

    Författare :Gullvi Flensner; Birgitta Engström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; action-theory; cooling; daily life; fatigue; perceived health; phenomenology; scale testing; MEDICINE; MEDICIN; Nursing; Vårdvetenskap;

    Sammanfattning : The overall aim of this thesis was to gain knowledge about experiences of fatigue among individuals diagnosed with MS and to compare these experiences with those of individuals in the general population. Individuals' experiences of fatigue have been approached both inductively and deductively and qualitative and quantitative research methods have been combined. LÄS MER
