  2. 6. Microextraction for usage in environmental monitoring and modelling of nitroaromatic compounds and haloanisoles

    Author : Sofie Jönsson; Bert van Bavel; Tomas Öberg; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PCA; PLS; QSPR; SPME; MEPS; nitroaromatic compounds; TCA; TBA; Chemistry; Kemi; Kemi; Chemistry;

    Abstract : Processes in the environment are often complex and the description and prediction of the behaviour of environmental pollutants requires sophisticated methodology including multidimensional technology. Multivariate statistical methods including principal component analysis (PCA) and partial least squares projection to latent structures (PLS) were used to characterise several nitroaromatic compounds according to a large number of chemical and physical properties.

  4. 7. Chemoinformetics for green chemistry

    Author : Tao Liu; Tomas Öberg; Ian Nicholls; Bert van Bavel; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QSPR; PLS; Chemometrics; Chemoinformatics; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

    Abstract : This thesis focuses on the development of quantitative structure-activity relationship (QSPR) models for physicochemical properties, e.g., vapor pressure and partitioning coefficients. Such models can be used to estimate environmental distribution and transformation of the pollutants or to characterize solvents properties. READ MORE

  5. 8. The Conditions for Multi-Level Governance : Implementation, Politics, and Cooperation in Swedish Active Labor Market Policy

    Author : Martin Lundin; PerOla Öberg; Jörgen Hermansson; Tomas Bergström; Uppsala universitet; []
    Keywords : Political science; Governance; Intergovernmental relations; Implementation; Cooperation; Political parties; Active labor market policy; Sweden; Statsvetenskap;

    Abstract : How can the central state direct local public units to work effectively towards public sector goals? In an effort to understand the conditions for governance, the three self-contained essays housed in this thesis examine the role of central and local government agencies in implementation of active labor market policy (ALMP) in Sweden. The study is based on new and unique quantitative data. READ MORE
