  1. 6. Sustainable snow handling

    Författare :Karin Reinosdotter; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Urban snow contains pollution that originates from sources such as atmospheric precipitation, traffic emission, and de-icing chemicals. These pollutants accumulate in the snow during the winter and are released when the snow starts to melt. LÄS MER

  3. 7. Seasonal snow storage for space and process cooling

    Författare :Kjell Skogsberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : The world’s cooling demand has increased considerably during the last decades due to increased population, industrialisation, comfort demands, electronic equipment usage and new building technologies. Conventional cooling is often produced by electrically driven devices. LÄS MER

  4. 8. The effect of anti-slip devices on pedestrian safety : method development and practical test

    Författare :Glenn Berggård; Christer Hydén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Engineering; Trafikteknik;

    Sammanfattning : Every winter, more than 100,000 pedestrians in the Nordic countries receive medical treatment as a result of falls on slippery surfaces. In addition, the risk of injury reduces interest in outdoor activities during the wintertime. LÄS MER

  5. 9. Evaluation of Swedish Ice Cleat Distribution Programs : From Program Design to Ice Cleat Use

    Författare :Robin Holmberg; Carl Bonander; Johanna Gustavsson; Mikael Svensson; Agneta Larsson; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; program evaluation; ice cleats; anti-slip devices; usage rates; older adults; Risk and Environmental Studies; Risk- och miljöstudier;

    Sammanfattning : Winter conditions, characterized by snow and lowered temperatures, can make travel by foot difficult. Older adults aged 65 and above are especially at risk of slipping and falling on icy or snowy surfaces. Minor falls can result in severe injuries due to their frailty. LÄS MER

  7. 10. Urban Snowmelt Processes: Modelling and Observation

    Författare :Annette Semadeni Davies; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; energy; runoff; snow properties; heterogeneity; hydrological modelling; Urbanisation; snowmelt; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : In northern Scandinavia and other cold regions, urban drainage systems are often unable to cope with the high volumes of melt water which can be sustained for several weeks. High waste water treatment plant inflows, combined system overflows and low water quality are a few problems associated with snowmelt. LÄS MER
