21. Binding of benzo(a)pyrene metabolites and derivatives to DNA : characterization using optical spectroscopy techniques
Sammanfattning : DNA with covalently bound benzo(a)pyrene (BP) derivatives was studied with fluorescence spectroscopy, fluorescence decay measurements, fluorescence quenching measurements, light absorption and linear dichroism of flow oriented samples. The modified DNA was prepared in three different ways: (1) by incubating calf thymus DNA with rat liver micromomes, necessary cofactors and benzo(a)pyrene or derivatives of benzo(a)pyrene, (2) by isolating DNA.

24. Lip-motion and speech biometrics in person recognition
Sammanfattning : Biometric identification techniques are frequently used to improve security, e.g. in financial transactions, computer networks and secure critical locations. The purpose of biometric authentication systems is to verify an individual by her biological characteristics including those generating characterisitic behaviour. LÄS MER
25. Optical Diagnostics for Quantitative Potassium Chemistry in Biomass Thermochemical Conversion Processes
Sammanfattning : Biomass is an essential sustainable and carbon-neutral energy source. Through thermochemical conversion processes, such as combustion and gasification, biomass can generally be used in boilers to provide heat and/or power. Biomass fuels contain varying amounts of potassium, chlorine and sulfur. LÄS MER
