2. 1. Integrated design and construction for bridges: key aspects and benefits

   Author : Daniel P T Ekström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrialized construction; ICT; concurrent engineering; BIM; integrated design; Lean Construction; Integration in construction;

   Abstract : The rate of productivity and innovation capacity within the Swedish construction industry of today is perceived to lead to a poor return of investment within infrastructures. Bridges, are commonly designed for a long service-life, and all stages after realization is greatly dependent on and constrained by decisions made during design and construction of the structure.

5. 3. Emission estimation based on traffic models and measurements

   Author : Nikolaos Tsanakas; Jan T. Lundgren; Joakim Ekström; Johan Olstam; Marcus Gerstenberger; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Traffic congestion increases travel times, but also results in higher energy usage and vehicular emissions. To evaluate the impact of traffic emissions on environment and human health, the accurate estimation of their rates and location is required. READ MORE

6. 4. Bacterial Regulation of Peripheral Immunity : Mechanistic insights from lactobacilli and Staphylococcus aureus

   Author : Manuel Mata Forsberg; Eva Sverremark-Ekström; Monika Brunner-Weinzierl; Stockholms universitet; []

   Abstract : There is a constant cross-talk between our immune system and the colonizing microbiota. The gut resident bacteria produce a broad range of molecules with regulatory activities in both local and distal tissues. Staphylococcus (S. READ MORE

7. 5. Lactobacilli- and Staphylococcus aureus mediated modulation of immune responses in vitro

   Author : Yeneneh Haileselassie; Eva Sverremark-Ekström; Huub Savelkoul; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; lactobacilli; staphylococcus aureus; dendritic cells; retinoic acid; epithelial cells; T cells; immunologi; Immunology;

   Abstract : The human gut harbors a vast number of microbes. These microbes are not passive bystanders. They are important in modulating the immune system. We have previously shown that early colonization with lactobacilli and Staphylococcus (S. READ MORE
