  1. 16. A broad perspective on life cycle considerations in product development

    Författare :Ingrid Hallander; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : For products with long life cycles, operational and support costs represent a significant part of the total cost for the product. Moreover, such products frequently tend to be complex and contain a mixture of both mature. stable technology with bng life cycles and new technology with short life cycles. LÄS MER

  3. 17. Geographic variation in life cycles : Local adaptation and ecological genetics in a temperate butterfly

    Författare :Olle Lindestad; Karl Gotthard; Sören Nylin; Christopher W Wheat; Greg Ragland; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; voltinism; local adaptation; insect; life cycle; seasonality; genomics; life history; zoologisk ekologi; Animal Ecology;

    Sammanfattning : Conditions in nature change with the seasons, necessitating seasonal adaptations that synchronize the life cycles of organisms with their surroundings. Such regulatory adaptations must vary between populations to track local variation in climate and seasonality; this local adaptation is facilitated by locally specific seasonal cues, but may be hampered by gene flow and genetic history.

  4. 18. Observing and Modeling Precipitation in the Tibetan Plateau region - from large-scale processes to convective storms

    Författare :Julia Kukulies; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tibetan Plateau; Water cycle; Precipitation; Climate modeling; Mesoscale convective systems; Large-scale atmospheric circulation;

    Sammanfattning : Climate change in mountain regions has far-reaching societal impacts such as increased risks for natural hazards and water scarcity that may affect billions of people in the downstream regions. Precipitation changes play a critical role in these impacts due to their effects on river runoff and flooding. LÄS MER

  5. 19. Modeling and Testing of Insulation Degradation due to Dynamic Thermal Loading of Electrical Machines

    Författare :Zhe Huang; Industriell elektroteknik och automation; []
    Nyckelord :thermal degradation; thermal cycle; dynamic temperature; thermal-mechanical; fatigue; electrical insulation system; accelerated testing; condition monitoring; electrical machine; electrified vehicles;

    Sammanfattning : Electrical machines in electrified vehicles are subjected to dynamic loadings at different driving conditions, which results in dynamic temperatures. The aging of the Electrical Insulation System (EIS) in electrical machines is caused by these dynamic temperatures, namely high average temperatures and temperature cycles. LÄS MER

  7. 20. Cell cycle control in G1 : restriction points for growth factors and anchorage dependence

    Författare :Peter Zickert; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cell cycle; cyclin E; growth control; growth factor; restriction point; ECM; anchorage;

    Sammanfattning : Background: The eukaryotic cell cycle consists of four well-defined phases. During the S phase DNA is replicated and during the M phase the chromosomes are segregated to daughter cells. The time gap between completion of M phase and entry into S phase is called G1. The time gap between S phase and mitosis is called G2. LÄS MER
