  2. 1. Microbes Associated with Hylobius abietis : A Chemical and Behavioral Study

    Author : Muhammad Azeem; Anna Karin Borg-Karlson; Irena Valterová; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hylobius; Ewingella; Penicillium; Heterobasidion; Bacteria; Fungi; Bark; Forest waste; Metabolites; Styrene; Methyl salicylate.;

    Abstract : This thesis is based on three inter-related studies: the first part deals with the microbial consortium, the identification of microbes and their volatiles, the second part deals with the study of bio-chemical control methods of two conifer pests; the pine weevil Hylobius abietis (L.) and the root rot fungi Heterobasidion spp. READ MORE

  4. 2. Physiologically based pharmacokinetic modeling in risk assessment - Development of Bayesian population methods

    Author : Fredrik Jonsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; methyl chloride; dichloromethane; toluene; styrene; uncertainty; intra- individual variability; risk assessment; physiologically based modeling; Markov chain Monte Carlo; PBPK; Bayesian; population modeling; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Biopharmaceutics; biofarmaci;

    Abstract : In risk assessment of risk chemicals, variability in susceptibility in the population is an important aspect. The health hazard of a pollutant is related to the internal exposure to the chemical, i.e. the target dose, rather than the external exposure. READ MORE

  5. 3. Chemical exposure in the work place : mental models of workers and experts

    Author : Anita Pettersson-Strömbäck; Bengt Järvholm; Steven Nordin; Bo Strangert; Marianne Törner; Umeå universitet; []
    Keywords : self-assessment of exposure; predictions; expert judgment; risk; interpretation; time series analysis; MAPE; benzene; monoterpenes; styrene; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Many workers are daily exposed to chemical risks in their work place that has to be assessed and controlled. Due to exposure variability, repeated and random measurements should be conducted for valid estimates of the average exposure. READ MORE

  6. 4. Palladium(II)-Catalysed Heck and Addition Reactions : Exploring Decarboxylative and Desulfitative Processes

    Author : Bobo Skillinghaug; Mats Larhed; Antonio de la Hoz Ayuso; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palladium; catalysis; palladium II catalysis; synthesis; Heck; carboxylic acid; sulfinic acid; sodium sulfinate; nitrile; styrene; ketone; aryl ketone; electrospray ionization mass spectrometry; density functional theory; microwave heating; continuous flow; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Palladium complexes have the ability to catalyse cross-coupling of two organic moieties through the formation of transient metal-carbon bonds, thus bringing them closer to each other to facilitate the formation of a new bond. Palladium-catalysed coupling reactions are one of the most important carbon-carbon forming reactions available to organic chemists and many of these reactions rely on the reactivity of aryl-palladium complexes.

  7. 5. Palladium-Catalyzed Carbonylation and Arylation Reactions

    Author : Jonas Sävmarker; Mats Larhed; Gary Molander; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; palladium; carbonylation; styrene; amidine; aryl ketones; aryl sulfinates; ESI-MS; aryltrifluoroborates; Organic Pharmaceutical Chemistry; Organisk farmaceutisk kemi;

    Abstract : Palladium-catalyzed reactions have found widespread use in contemporary organic chemistry due to their impressive range of functional group tolerance and high chemo- and regioselectivity. The pioneering contributions to the development of the Pd-catalyzed C-C bond forming cross-coupling reaction were rewarded with the Nobel Prize in Chemistry in 2010. READ MORE
