21. Microorganisms in indoor environments. A search for health-related measurements
Abstract : Microorganisms are ubiquitous in indoor air and epidemiological data suggest that inhalation of microbes and/or their products adhered on air–borne dust particles can impair well–being and health. In the present thesis microbial volatile organic compounds (MVOCs) and cellular markers were studied by gas chromatography–mass spectrometry (GC/MS). READ MORE

22. Pheromone production in the butterfly Pieris napi L
Abstract : Aphrodisiac and anti-aphrodisiac pheromone production and composition in the green-veined white butterfly Pieris napi L. were investigated.Aphrodisiac pheromone biosynthesis had different time constraints in butterflies from the diapausing and directly developing generations. READ MORE

23. On chip integrated sample preparation for proteomics
Abstract : The aim of this thesis project has been to create miniaturized analytical tools that improve sample preparation for the very rapidly growing field of proteomics research. The presented miniaturized analytical tools provide novel and generic analytical solutions, which are highly adaptable for analysis of various low abundant biomolecules. READ MORE

24. Volatiles of Conifer Seedlings : Compositions and Resistance Markers
Abstract : Pine weevils cause major damage to newly planted conifer seedlings in reforestation areas. However, recent findings indicate that small (“mini”) seedlings, planted at the age of 7-10 weeks, are gnawed less by pine weevils than the larger, conventionally planted seedlings. READ MORE

25. Improved methods for enrichment of organic ultra trace components for analysis by gas chromatography
Abstract : This thesis describes some new methods for analysis oforganic trace components from air and water by gaschromatography. The work is particularly focused on thedevelopment of new technologies for analyte enrichment, usingsorbent-based concepts. Short lengths of open tubular columnswere examined for their potential use as denuders. READ MORE
