  4. 7. Differences in glycemic control in type 1 diabetes children and adolescents : in a national and international perspective and the effect on microvascular complications in young adults

    Author : Johan Anderzén; Ulf Samuelsson; Lena Hanberger; Karin Åkesson; Carina Sparud Lundin; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : This thesis focuses on glycemic control measured as HbA1c in type 1 diabetes (T1D) patients during childhood and especially during adolescence, both in a Swedish and an international context, and relates the glycemic control to the risk of complications in young adults.  In studies I and II, the Swedish Pediatric Diabetes Quality Register (SWEDIABKIDS) and the Swedish National Diabetes Register (NDR) were used.

    Abstract : One of the main challenges in order to make electric cars competitive with gas-powered cars is in the improvement of the electric power system. Although many of the energy sources currently used in electric vehicles have sufficientlyhigh specific energy, their applicability is limited due to low specific power. READ MORE

  7. 10. Engaging in Urban Living Lab Co-design

    Author : Esbjörn Ebbesson; Vaike Fors; Jesper Lund; Johan Lundin; Högskolan i Halmstad; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban Living Labs; Participatory Design; CoDesign;

    Abstract : Urban Living Labs (ULL) have become a common way to address wicked design challenges within the future mobility, and smart city context. The move toward ULL is part of a paradigm shift away from focusing purely on the IT-artifact, innovation, and user-centeredness toward focusing on the urban context and the construction of a place as a social context rather than implementation of a product or service in isolation.
