1. Prehospital medical management in Swedish road tunnel incidents
Sammanfattning : 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. LÄS MER
2. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions
Sammanfattning : 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. LÄS MER
3. Fire safety design of road tunnels
Sammanfattning : 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. LÄS MER
4. Durability of fire exposed concrete : Experimental Studies Focusing on Stiffness & Transport Properties
Sammanfattning : 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. LÄS MER
5. Pollutant profiles as tools for characterisation of environmental exposure
Sammanfattning : 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.
