2. 6. Methodologies to assess the fate of polar organic compounds in aquatic environments

   Author : Jörgen Magnér; Tomas Alsberg; Dag Broman; Jan-Åke Jönsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Passive equilibrium sampler; Absorbent; Polar organic compounds; Liquid chromatography-mass spectrometry; Partitioning coefficient; Fulvic acid; Sediment; PEVAC; Bag-SPE; Solid phase extraction; Pharmaceuticals; Wastewater; Sea water; UPLC-QToF; Environmental chemistry; Miljökemi; Analytical chemistry; Analytisk kemi; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Polar organic compounds (POCs) are chemicals with polar functional groups in their structure. The functional groups make the compounds hydrophilic and less prone to partition with biota. However, the knowledge of their fate is limited due to difficulties associated with their measurements.

4. 7. Localised Radial Basis Function Methods for Partial Differential Equations

   Author : Victor Shcherbakov; Elisabeth Larsson; Grady B. Wright; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radial basis function; Partition of unity; Computational finance; Option pricing; Credit default swap; Glaciology; Fluid dynamics; Non-Newtonian flow; Anisotropic RBF; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

   Abstract : Radial basis function methods exhibit several very attractive properties such as a high order convergence of the approximated solution and flexibility to the domain geometry. However the method in its classical formulation becomes impractical for problems with relatively large numbers of degrees of freedom due to the ill-conditioning and dense structure of coefficient matrix.

5. 8. Studies on dephosphorisation during steelmaking

   Author : Somnath Basu; Seshadri Seetharaman; Nobuo Sano; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

   Abstract : This work is aimed at understanding the thermodynamic principles influencing the phosphorus partition between slag and steel during steelmaking, particularly during refining of high-phosphorus hot metal using the basic oxygen steelmaking (BOS) process. Mapping of the slag path has been carried out using a mass balance model based on input conditions and off-gas analysis, which has been validated by intermediate measurements of slag and metal composition in an industrial basic oxygen furnace (BOF).

6. 9. Essays on Income Risk and Inequality

   Author : Karl Harmenberg; Per Krusell; Fatih Guvenen; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; income risk; income inequality; consumption; durable goods; cyclical skewness; top-income inequality; gender gap; glass ceiling; assortative mating; Economics; nationalekonomi;

   Abstract : Consumption Dynamics under Time-Varying Unemployment Risk We study the response of households' demand for durable goods to fluctuations in unemployment risk. First, using survey data, we document that household durable expenditures react strongly to unemployment risk, while the effect on nondurable expenditures is indistinguishable from zero. READ MORE

7. 10. Protein Surfaces Probed by Aqueous Two-phase Partitioning

   Author : Kristina Berggren; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; partitioning; Aqueous two-phase systems; protein surface; peptide; Biochemistry; amino acid residue; Biokemi;

   Abstract : This thesis is concerned primarily with peptide and protein partitioning in aqueous two-phase systems and the connection between partitioning behavior and protein structure. The surface properties of a protein is often crucial for recognition and interaction with other molecules. READ MORE
