1. 21. Life Cycle Assessment of Asphalt Roads : Decision Support at the Project Level

   Författare :Ali Azhar Butt; Björn Birgisson; Nicole Kringos; Susanna Toller; Stephen T. Muench; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt roads; life cycle assessment; feedstock energy; warm mix asphalt additives; green procurement; decision support; laboratory investigation; pavement design.; Byggvetenskap; Civil and Architectural Engineering; Transportvetenskap; Transport Science;

   Sammanfattning : Transport infrastructures such as roads are assets for the society as they not only ensure mobility but also strengthen society’s economy. Considerable amount of energy and materials, that include bitumen, aggregates and asphalt, are required to build and maintain roads. LÄS MER

3. 22. Making Sense of Making Sense - Exploring users’ understanding of automated vehicles during use

   Författare :Mikael Johansson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Automated vehicles; Driving automation; Make sense; Product semantics; Signifiers; Meaning; Conceptual model; Understanding;

   Sammanfattning : Automation has for a long time been embraced by the vehicle industry and in recent years, the amount and sophistication of automation in vehicles have rapidly increased, creating more advanced automated vehicle (AV) systems. The complexity of AVs does not only pose a technical challenge, but the entry of automation into vehicles also creates new dynamics in the human-vehicle interaction, that puts new demands on the user.

4. 23. Synthesis and modification of potential CO2 adsorbents : Amine modified silica and calcium carbonates

   Författare :Baroz Aziz; Niklas Hedin; Lennart Bergström; Helmut Cölfen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amine-modified silica; carbon capture; Fractional factorial design; IR spectroscopy; calcium carbonate; Materials Chemistry; materialkemi;

   Sammanfattning : The prospect of rapid changes to the climate due to global warming is subject of public concern. The need to reduce the emissions of atmospheric green house gases and in particular carbon dioxide is greater than ever. Extensive research is performed to find new solutions and new materials, which tackles this problem in economically benign way. LÄS MER

5. 24. Crossflow Microfiltration of particle Suspensions - The influence of hydrodynamics and physico-chemical interactions

   Författare :Ingmar Harald Huisman; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; ceramic membranes; shear-induced diffusion; crossflow microfiltration; silica particles; zeta potential; Livsmedelsteknik;

   Sammanfattning : Crossflow microfiltration is a technique to separate suspended particles (or cells or droplets) from liquids by use of a membrane that is permeable for the liquid but impermeable for the particles. The permeate flow drives particles to the membrane surface, where they may be deposited and form a fouling layer. LÄS MER

7. 25. The role of freshwater phytoplankton in the global carbon cycle

   Författare :Fabian Engel; Gesa A. Weyhenmeyer; Don Pierson; Katrin Attermeyer; John A. Downing; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; carbon dioxide; lake; river; global limnology; spatial scale; carbon budget;

   Sammanfattning : Water flowing through the landscape transports chemical substances including carbon. Along the way from upland soils to the ocean, carbon is transformed from organic carbon into inorganic carbon and vice versa. One such carbon transformation process is the uptake of carbon dioxide (CO2) from the water phase by phytoplankton. LÄS MER
