1. Interaction Between Graphene Derivatives and Asphaltenes in Crude Oil and Crude Derivatives
Sammanfattning : 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. LÄS MER
2. Life Cycle Assessment of Asphalt Pavements including the Feedstock Energy and Asphalt Additives
Sammanfattning : 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. LÄS MER
3. On the chemical state and mobility of lead and other trace elements at the biogeosphere/technosphere interface
Sammanfattning : 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. LÄS MER
4. Regional and local surface ozone variations in relation to meteorological conditions in Sweden
Sammanfattning : 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. LÄS MER
5. A model for simulation and generation of surrounding vehicles in driving simulators
Sammanfattning : 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. LÄS MER
