  1. 1. Brash Ice and Level Ice Growth, Effects of Snow

    Författare :Vasiola Zhaka; Andrzej Cwirzen; Kaj Riska; Robert Ettema; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brash ice growth; level ice growth; snow effects; slush; snow ice; macroporosity; piece size distribution; Byggmaterial; Building Materials;

    Sammanfattning : Brash ice occurs due to frequent navigation in ice-infested waters, typically along established navigation tracks regularly maintained by icebreakers and harbors. The accumulation and consolidation of brash ice between two ship passages are influenced by meteorological factors including the cumulative freezing air temperatures, and the mechanical processes such as ice-breaking due to ship passages.

  4. 3. Accident Risk and Environmental Assessment : Development of an Assessment Guideline with Examination in Northern Scandinavia

    Författare :Markus Lundkvist; Lennart Strömquist; Christer Jonasson; Rolf Nyberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geography; accident; risk; hazard; environmental assessment; geomorphology; railway; road; avalanche; debris flow; rock fall; slush flow; torrent; moose; reindeer; environmental impact assessment; proposal alternatives; Kiruna; Narvik; Geografi; Other earth sciences; Övrig geovetenskap;

    Sammanfattning : In environmental impact assessment (EIA), accident risk should be considered as one impact. However, few studies have compared assessed risk levels with documented accidents. There is thus a need for assessing accuracy of risk assessment methodologies. LÄS MER

  5. 4. Service life of repaired concrete bridge decks

    Författare :Johatan Paulsson-Tralla; KTH; []
    Nyckelord :;

    Sammanfattning : Pre-mature deterioration of reinforced concrete causesproblems world-wide and the search for reliable cost effectiveand environmental friendly repairs is intense. The service lifeof the repaired structure is important in order to establishthe annual cost and environmental impact for differentalternatives. LÄS MER

  7. 5. Winter maintenance and cycleways

    Författare :Anna Bergström; KTH; []
    Nyckelord :cycleways; winter maintenance; maintenance service level; mode choice; winter cycling frequency; winter road condition assessment; bicycle measurements; friction measurement; winter maintenance equipment;

    Sammanfattning : Increasing cycling as a means of personal travel couldgenerate environmental benefits if associated with acorresponding decrease in car-based transport. In seeking topromote cycling in wintertime, it is desirable to understandhow important the road surface condition is compared to otherfactors in people's decision to cycle or not. LÄS MER
