  1. 1. Polypropylene Morphology, defects and electrical breakdown

    University dissertation from Stockholm : KTH

    Author : Sari J. Laihonen; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; polypropylene; poly propylene-stat-ethylene ; crystal structure; morphology; crystallinity; crystallization kinetics; lamellae; spherulite; defect; Kemiteknik; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : Crystal structure, morphology and crystallization kinetics of melt-crystallized polypropylene and poly(propylene-stat-ethylene) fractions with 2.7 to 11.0 mol% of ethylene were studied by differential scanning calorimeter, wide- and small-angle X-ray scattering, polarized light microscopy, transmission electron microscopy and infrared spectroscopy.

  2. 2. A Gill Filament EROD Assay Development and Application in Environmental Monitoring

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Maria Jönsson; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; aquatic; benzo[a]pyrene; biomarker; CYP1A; environmental monitoring; EROD; fish; gill; indigo; PCB; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : A gill filament-based assay for the cytochrome P450 1A (CYP1A)-catalysed activity ethoxyresorufin O-deethylase (EROD) was developed in rainbow trout (Oncorhynchus mykiss) and applied to Atlantic salmon (Salmo salar), Arctic charr (Salvelinus alpinus), Atlantic cod (Gadus morhua), saithe (Pollachius virens), and spotted wolffish (Anarhichas minor). Exposure to waterborne β-naphthoflavone (βNF; 10-6 M) induced branchial EROD activity in all species but the spotted wolffish. READ MORE

  3. 3. On the lateral organisation of the thylakoid membrane

    University dissertation from Department of Biochemistry, Lund University

    Author : Ravi Danielsson; Lunds universitet.; Lund University.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thylakoid membrane heterogeneity; Plant biochemistry; Växtbiokemi; Thylakoid structure; Phase partition; Thylakoid fractions;

    Abstract : Popular Abstract in Swedish Allt liv på jorden bygger på fotosyntesen. Det är den process där växterna fångar upp solljuset och gör om det till kemisk energi. Med den energin producerar de syret i luften och kolhydrater för sin egen tillväxt, med kol från luftens koldioxid. READ MORE

  4. 4. On multiscale modeling of pearlitic steel

    University dissertation from Department of Biochemistry, Lund University

    Author : Erik Lindfeldt; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cementite; crystal plasticity; Pearlite; multiscale modeling; computational homogenization; digital image correlation; ferrite; in-situ SEM;

    Abstract : By studying pearlitic steels using a scanning electron microscope it can be observed that pearlite is a two-phase material with cementite lamellae embedded in a matrix of ferrite. The cementite is commonly described as being stiff and brittle in comparison to the ferrite which is considered to have a soft and ductile mechanical behavior. READ MORE

  5. 5. The Molecular Architecture of the Chloroplast Thylakoid Membrane. Mapping of protein complexes in different structural domains and effect of light induced protein phosphorylation on domain composition

    University dissertation from Department of Biochemistry, Lund University

    Author : Hreinn Stefánsson; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; cytochrome b f; aqueous two phase partitioning; Grana margin; NADPH dehydrogenase; Metabolism; Biokemi; metabolism;

    Abstract : Non-detergent procedure for isolation of sub-thylakoid vesicle populations derived from different structural domains of the chloroplast thylakoid membrane has been developed. Sub-thylakoid vesicles representing the grana, grana core, stroma lamellae and the grana margins have been isolated and their protein composition has been investigated. READ MORE
