11. Optical spectroscopy and fluorescence imaging for cancer diagnostics
Sammanfattning : This work presents optical methods for diagnosing cancer. A complementary method for diagnosing eye cancer was investigated using a technique developed within this work named transscleral optical spectroscopy (TOS). LÄS MER
12. Application and Development of Optical Soot Diagnostic Techniques
Sammanfattning : Internal combustion engines (ICE) have been a vital part of society ever since their inception more than a hundred years ago. While initially it seemed as if the replacement of horse and carriage had solved the issue with pollutant emissions, it became evident in the 60’s that emission from ICEs is a major concern. LÄS MER
13. Substance flow analyses of metals and organic compounds in an urban environment : – the Stockholm example
Sammanfattning : The intensified use of materials, products and goods in our time involves massive consumption of metals and organic compounds that can be released from society to the environment in the various stages of production, use and waste. Depending on the circumstances this may give rise to environmental risks, as metals in general and certain organic substances may be toxic in the short or long term. LÄS MER
14. Studies of auroral processes using optical methods
Sammanfattning : The Aurora is a visual manifestation of the complex plasma processes that occur as the solar wind interacts with the Earth’s magnetosphere and ionosphere. Therefore, studies of the aurora can lead to better understanding of the near-Earth space environment and of fundamental physical processes. LÄS MER
15. Injection and Combustion of Alternative Fuels in Spark Ignited Direct Injection Engines
Sammanfattning : Increasingly stringent vehicle emission legislation necessitates increasingly efficient combustion engines. The use of direct injection in spark ignited engines improves engine efficiency and reduces CO2 emissions. LÄS MER
