  1. 1. Diffusion studies in gels using holographic laser interferometry

    University dissertation from Chemical Engineering 1, Lund University

    Author : Charlotte Mattisson; Lund University.; Lunds universitet.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical potential; ionic strenght; pH; cubic phase; partition coefficient; holographic laser interferometry; holography; pullulan; lysozyme; BSA; macromolecules; diffusion; gel; Poisson-Boltzmann; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : This thesis is an investigation of the potential of holographic laser interferometry for the study of diffusion of both small solutes and macromolecules. An investigation on the importance of errors due to light deflection in refarctive index gradients showed that the magnitude of the refractive index gradients were negligible for the system investigated.

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

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Author : Jörgen Magnér; Stockholms universitet.; [2010]
    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; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; tillämpad miljövetenskap; Applied Environmental Science;

    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.

  5. 5. Localised Radial Basis Function Methods for Partial Differential Equations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Victor Shcherbakov; Uppsala universitet.; Uppsala universitet.; [2018]
    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.
