  2. 1. Interaction Between Graphene Derivatives and Asphaltenes in Crude Oil and Crude Derivatives

    Author : Govindan Induchoodan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micelle Structures; Material enhancement; Enhanced Roads; Graphene; Asphaltene deposition; Structure-Function;

    Abstract : The chemistry of crude oil (SARA) and crude derivatives, and the percentage of asphaltene can vary significantly depending on external and internal factors such as the source and method of SARA extraction. If graphitic materials are introduced into a system such as SARA, it becomes an additional variable to a complex multi-phase colloid. READ MORE

  4. 2. Life Cycle Assessment of Asphalt Pavements including the Feedstock Energy and Asphalt Additives

    Author : Ali Azhar Butt; Björn Birgisson; John Harvey; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Life Cycle Assessment; feedstock energy; asphalt binder additives; mass-energy flows; bitumen healing; wax; polymer;

    Abstract : Roads are assets to the society and an integral component in the development of a nation’s infrastructure. To build and maintain roads; considerable amounts of materials are required which consume quite an amount of electrical and thermal energy for production, processing and laying. READ MORE

  5. 3. On the chemical state and mobility of lead and other trace elements at the biogeosphere/technosphere interface

    Author : Mattias Bäckström; Gunnar Jacks; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lead; trace elements; traffic; shooting range; peat; sediments; speciation; biokemi; Chemistry; Kemi; Kemi; Chemistry;

    Abstract : Most inorganic contamination has occurred at the interface between the technosphere and the biogeosphere, even though atmospheric emissions have affected the entire globe. Several human activities now pose a substantial threat towards human health and the ecosystems. READ MORE

  6. 4. Regional and local surface ozone variations in relation to meteorological conditions in Sweden

    Author : Lin Tang; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LWTs; surface ozone; high-ozone events; long-range transport; TAPM; MM5; NOx-O3; Sweden;

    Abstract : Air quality is strongly dependent on meteorological conditions. Atmospheric circulation encapsulates general information about local meteorological variables to some extent, and can serve as an explanatory variable for air quality at a regional or local scale. READ MORE

  7. 5. A model for simulation and generation of surrounding vehicles in driving simulators

    Author : Johan Olstam; Jan Lundgren; Pontus Matstoms; Stéphane Espié; Linköpings universitet; []
    Keywords : Traffic; Simulation; Model; Traffic flow; Vehicle; Micro; Overtaking; Vehicle spacing; Deceleration; Acceleration; Mathematical model; Simulator; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

    Abstract : Driving simulators are used to conduct experiments on for example driver behavior, road design, and vehicle characteristics. The results of the experiments often depend on the traffic conditions. One example is the evaluation of cellular phones and how they affect driving behavior. READ MORE
