  2. 1. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements

    Author : Annika Lundmark; Per-Erik Jansson; Bo Olofsson; Ann-Catrine Norrström; Helen K. French; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chloride; De-icing salt; Groundwater; Modelling; Monitoring; Road; Roadside; Soil water; Water in nature and society; Vatten i natur och samhälle;

    Abstract : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. READ MORE

  4. 2. Crash Compatibility between Roadside Infrastructure and Passenger Vehicles: Improving the Geometric and Structural Compatibility to Reduce Fatalities

    Author : Weijia Wu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crash simulations.; ditches; accident analysis; crash compatibility; guardrails; roadside safety;

    Abstract : Roadside accidents cause a significant number of fatalities each year in the world. To reducethis type of accident, roadside infrastructure needs to be investigated to improve protection todifferent kinds of passenger vehicles during crashes. READ MORE

  5. 3. De-icing salt and the roadside environment : Air-borne exposure, damage to Norway spruce and system monitoring

    Author : Göran Blomqvist; KTH; []
    Keywords : road; de-icing salt; air-borne; environmental impact; vegetation damage; Norway spruce; seedling; follow-up; monitoring; indicator;

    Abstract : After decades of investigation, we still have to deal withthe problem of environmental effects of the use of de-icingsalt on roads. Lacking useful indicators of the system, westill do not know the environmental utility of ameliorativemeasures taken. READ MORE

  6. 4. Road traffic metals : sources and emissions

    Author : David Hjortenkrans; Bo Bergbäck; Per-Arne Malmqvist; Högskolan i Kalmar; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission patterns; Heavy metals; Roadside soil; Sweden; Traffic; Sequential extractions; SFA; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

    Abstract : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. READ MORE

  7. 5. Alien Places in Late Soviet Science Fiction : The "Unexpected Encounters" of Arkady and Boris Strugatsky as Novels and Films

    Abstract : This dissertation deals with how science fiction reflects the shift in cultural paradigms that occurred in the Soviet Union between the 1960s and the 1970s. Interest was displaced from the rational to the irrational, from a scientific-technologically oriented optimism about the future to art, religion, philosophy and metaphysics. READ MORE
