  1. 1. Studies of the Elemental Composition of Airway Surface Liquid with Relevance to Cystic Fibrosis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Viengphet Vanthanouvong; Uppsala universitet.; [2006]
    Keywords : Anatomy; airway surface liquid; cystic fibrosis; Na; K; Cl; X-ray microanalysis; Anatomi;

    Abstract : Cystic fibrosis (CF) is an inherited disease with symptoms mainly in the respiratory tract. The airway epithelium is covered with a thin layer of fluid, the airway surface liquid (ASL). The volume and composition of ASL are important in the pathogenesis of cystic fibrosis. The composition of ASL was determined. READ MORE

  2. 2. Transformation and Release of Potassium, Chlorine, and Sulfur from Biomass under Conditions Relevant to Dual Fluidized Bed Gasification

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Placid Tchoffor Atongka; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cl; release of K; Char gasification; and S;

    Abstract : The transformation and release of ash-forming elements during thermal conversion of biomass areconducive to ash-related problems, for example, agglomeration of bed material in fluidized beds. Theoccurrence and severity of these problems largely depend on the extent to which K, Cl, and S arereleased from biomass during thermal conversion processes. READ MORE

  3. 3. Heterogeneous Degradation and Recyclability of PP Studied by Imaging Chemiluminescence

    University dissertation from KFS AB

    Author : Mikael Hamskog; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; recyclability; mapping; surface; heterogeneity; heterogeneous; evaporation; ageing; hamamatsu; russel; ICL; CL; Irganox 1010; Irganox 1076; oxidation; hydroperoxide; radical; carbonyl; luminescence; chemiluminescence; imaging chemiluminescence; recycling; stabilization; polypropylene; degradation;

    Abstract : Oxidative degradation is a serious threat to long-term use and recyclability of polymers. Successful recycling of polymeric quality products requires characterization of the polymer material after reprocessing and use. READ MORE

  4. 4. Multiconfigurational perturbation theory

    University dissertation from Lund

    Author : Kerstin Andersson; Karlstads universitet.; Karlstads universitet.; [1992]
    Keywords : Electron correlation; CASSCF; multiconfigurational second-order perturbation theory; CASPT2; ozone; C; N; O; F; Si; P; S; Cl; Ni; benzene; pyridine; pyrazine; pyrimidine; pyridazine; s-triazine; electric properties; excited states; spectroscopic data;

    Abstract : The aim of the thesis is to analyze a method which describes the electron correlation in atoms and molecules. The method is based on Rayleigh-Schrödinger perturbation theory with a partitioning of the Hamiltonian into a fairly simple zeroth-order operator and a perturbation operator. READ MORE

  5. 5. Long-term properties of polyethylene films efficiency of a natural antioxidant

    University dissertation from Stockholm : KTH

    Author : Clara Strandberg; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer Technology; alfa-tocopherol; Polyethylene PE ; Thermal aging; Infrared Spectroscopy FT-IR ; Chemiluminescence CL ; Solid-phase microextraction SPME ; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : There is a growing awareness of the risks of pollution in biological systems and one potential problem is the synthetic antioxidants, used for e.g. the stabilisation of polymeric materials. Natural antioxidants are an interesting alternative, if the high efficiency and thermal stability of the synthetic compounds can be reached. READ MORE
