1. New Techniques for Chiral Separations
Abstract : Gas chromatography (GC) has been utilized for the study of enantiomer resolution of the atropisomers of PCBs, o,p´-DDD and o,p´-DDT. Different substituents and concentrations of cyclodextrin, capillary dimensions and type of stationary phase films have been investigated to achieve the resolution of as many of the atropisomers on one column as possible.

2. Pollinators and Insect Pollination in Changing Agricultural Landscapes
Abstract : Agricultural intensification and associated loss of semi-natural grasslands, has resulted in reduced landscape heterogeneity. A concomitant loss of forage and nest sites for pollinating insects has driven declines across several pollinator taxa. READ MORE

3. Estrogen receptor and multixenobiotic resistance genes in freshwater fish and snails: identification and expression analysis after pharmaceutical exposure
Abstract : Pharmaceuticals are today released into aquatic environments where they can interfere with organisms' biological processes.The general research objective was to analyze how aquatic freshwater organisms are affected by exposure to pharmaceuticals that are categorized by the EU as potential risk factors to the environment (i.e. READ MORE

4. Column Development in Capillary Electrophoresis and Electrochromatography for Bioanalytical Applications
Abstract : Analysis of biological samples can be a difficult task. This thesis covers a broad aspect of the analytical areas of capillary electrophoresis (CE) and capillary electrochromatography (CEC) in combination with mass spectrometry (MS) that are of great importance for achieving fast, accurate and sensitive bioanalyses.

5. Speeding up the Atmosphere : Experimental oxidation studies of ambient and laboratory aerosols using a flow reactor
Abstract : Apart from gases, the air we breath consist of tiny, so called, aerosol particles. A cubic metre of air in a relatively clean environment can consist of several billion aerosol particles. The impact of these particles on human health and on climate is significant. READ MORE
