11. 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
12. Development and Use of Optical Remote Sensing Methods for Studies of Megacity Air Pollution and Volcanic Gas Emissions
Sammanfattning : Optical Remote Sensing Techniques offers the opportunity to, in real-time, obtain line averaged measurements of gases in the lower and upper atmosphere. These techniques easily offer themselves to automatization, which increases their usability for e.g. LÄS MER
13. Development and Implementation of a Wireless Sensor Network for Volcanic Gas Emission Monitoring
Sammanfattning : Volcanic eruptions have great impacts on the life of the inhabitants in the surrounding areas and even to the global climate. Around 15-21×10 Tg/yr SO2 are injected to the troposphere and the stratosphere by the active volcanoes in the world[Halmer et al., 2002]. LÄS MER
14. Positron Emission Tomography and Magnetic Resonance Techniques in Diabetes
Sammanfattning : In order to further advance the field of diabetes research there is a great need for establishing validated non-invasive quantitative techniques to study the pancreas and other tissues of importance for blood glucose regulation. The general aim of this thesis was to explore magnetic resonance techniques and positron emission tomography as such tools. LÄS MER
15. Lithium-ion Battery Safety - Assessment by Abuse Testing, Fluoride Gas Emissions and Fire Propagation
Sammanfattning : Lithium-ion batteries offer high energy and power densities as well as long life time but have a more narrow stability window compared to other battery types and contain reactive and flammable materials. In case of overheating the battery cell can release gas (vent) and, at temperatures of about 150-200 °C, a so called thermal runaway can occur, that is a rapid self-heated temperature increase which is typically accompanied with a large release of smoke and gas, fire and a potential cell case explosion or gas explosion.
