  2. 1. Prehospital medical management in Swedish road tunnel incidents

    Author : Johan Hylander; Anton Westman; Britt-Inger Saveman; Lina Gyllencreutz; Michael Haney; Stephen Sollid; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Road tunnel; incident management; disaster medicine; emergency medical services; e-learning; education; ambulance commander;

    Abstract : Background: The complexity of modern road tunnel systems may delay an efficient rescue effort. Capable decision-making is needed to limit time to care. The Swedish ambulance commander, responsible for the on-scene ambulance personnel, may lack education and experience from managing road tunnel incidents. READ MORE

  4. 2. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions

    Author : Sofiia Miliutenko; Anna Björklund; Robert Karlsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cumulative Energy Demand CED ; Global Warming Potential GWP ; Life Cycle Assessment LCA ; road infrastructure; strategic planning;

    Abstract : Road infrastructure is essential in the development of human society, but has both negative and positive impacts. Large amounts of money and natural resources are spent each year on its construction, operation and maintenance. Obviously, there is potentially significantenvironmental impact associated with these activities. READ MORE

  5. 3. Fire safety design of road tunnels

    Author : Jonatan Gehandler; Avdelningen för Brandteknik; []
    Keywords : HUMANIORA; HUMANITIES; Brandsäkerhet; vägtunnlar; design; Riskbedömning; Road tunnel fire safety; Fire safety engineering; design framework; risk evaluation;

    Abstract : This thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. READ MORE

  6. 4. Durability of fire exposed concrete : Experimental Studies Focusing on Sti„ffness & Transport Properties

    Author : Joakim Albrektsson; Johan Silfwerbrand; Lars Boström; Manouchehr Hassanzadeh; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Fire; Polypropylene fibres; Durability; Tunnel; Damage assessment; Ultrasonic pulse velocity; Water absorption; Chloride migration; DIC; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Road and rail tunnels are important parts of the modern infrastructure. High strength concrete (HSC) is commonly used for tunnels and other civil engineering structures, since it allows high load carrying capacity and long service life. In general, Swedish road and rail tunnels should be designed for a service life of 120 years. READ MORE

  7. 5. Pollutant profiles as tools for characterisation of environmental exposure

    Author : Håkan Wingfors; Peter Haglund; Calle Nilsson; Georg Becher; Umeå universitet; []

    Abstract : This thesis is concerned with measurements of persistent organic pollutants (POPs) in environmental samples. The POPs consist of several groups of compound with many isomers, hence analysing POPs in a complex environment is a This thesis is concerned with measurements of persistent organic pollutants (POPs) in environmental samples.
