21. The OH/IR Star Population in the Galactic Center
Abstract : The OH/IR stars and M-type Mira variables, that form the topic of this thesis are in two important ways different from OH/IR stars found elsewhere in the Galaxy. Their location in the central few tens of parsecs of the Galactic center allows one to study the dynamics of the Galaxy on that scale, and to investigata a population of evolved stars with a high metal abundance.

22. Hydroxylated polybrominated diphenyl ethers in Baltic Sea biota : Natural production, food web distribution and biotransformation
Abstract : Hydroxylated polybrominated diphenyl ethers (OH-PBDEs) are naturally produced in aquatic ecosystems e.g. by algae. Many OH-PBDEs have been observed to be highly bioactive and to cause adverse effects through several pathways, e. READ MORE

23. Environmentally relevant chemical disruptors of oxidative phosphorylation in Baltic Sea biota : Exposure and toxic potentials
Abstract : This thesis focuses on toxicity and occurrence of hydroxylated polybrominated diphenyl ethers (OH-PBDEs) in Baltic Sea biota. The aims were to assess OH-PBDEs potency for disruption of oxidative phosphorylation (OXPHOS) and determine their and related compounds exposure in Baltic blue mussel, herring and long-tailed duck.

24. Synthesis of organobromines as a tool for their characterisation and environmental occurrence assessment
Abstract : Polybrominated diphenyl ethers (PBDEs) have been intensively used as flame retardants (FRs) and have become ubiquitous environmental pollutants. PBDEs form hydroxylated PBDEs (OH-PBDEs) as metabolites. Further, some OH-PBDEs and methoxy-PBDEs (MeO-PBDEs) are natural products. READ MORE

25. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines
Abstract : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. READ MORE
