1. Simplifying complex models : Application of modeling tools in exposure assessment of organic pollutants
Sammanfattning : Thousands of chemicals are used in society, but the exposure to humans and other organisms has been measured only for a small number of compounds. Modeling tools constitute low-cost and effective alternatives to measurements for the assessment of exposure. LÄS MER
2. Melting behaviour of reduced iron ore pellets and raceway adiabatic flame Temperature Characteristics in the Blast Furnace
Sammanfattning : .... LÄS MER
3. Models of the Distribution of Persistent Organic Pollutants in the Marine Environment
Sammanfattning : Persistent organic pollutants (POPs) is a group of chemicals that are toxic, undergo long-range transport and accumulate in biota. Due to their persistency the distribution and recirculation in the environment often continues for a long period of time. LÄS MER
4. Combining Models of Coronal Mass Ejections and Solar Dynamos
Sammanfattning : Observations show that Coronal Mass Ejections (CMEs) are associated with twisted magnetic flux configurations. Conventionally, CMEs are modeled by shearing and twisting the footpoints of a certain distribution of magnetic flux at the solar surface and letting it evolve at the surface. LÄS MER
5. Appropriate Modelling Complexity: An Application to Mass Balance Modelling of Lake Vänern, Sweden
Sammanfattning : This work is about finding an appropriate modelling complexity for a mass-balance model for phosphorus in Lake Vänern, Sweden. A statistical analysis of 30 years of water quality data shows that epilimnion and hypolimnion have different water quality and should be treated separately in a model. Further vertical division is not motivated. LÄS MER
