  2. 6. Through the magnifying glass - The big small world of marine meiofauna : Morphology, species and evolution in Nemertodermatida

    Author : Inga Meyer-Wachsmuth; Ulf Jondelius; Mark E Sidall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nemertodermatida; Acoelomorpha; morphology; CLSM; Phalloidin; musculature; DNA; cryptic species; species delimitation; dispersal; taxonomy; phylogenetics; IHC; nervous system; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Nemertodermatida is a group of microscopic marine worm-like animals that live as part of the marine meiofauna in sandy or muddy sediments; one species lives commensally in a holothurian. These benthic worms were thought to disperse passively with ocean currents, resulting in little speciation and thus wide or even cosmopolitan distributions. READ MORE

  4. 7. Morphology and material stability in polymer solar cells

    Author : Rickard Hansson; Ellen Moons; Andreas Opitz; Mats Fahlman; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer solar cell; photovoltaics; morphology; photo-degradation; conjugated polymer; fullerene; synchroton-based techniques; Physics; Fysik;

    Abstract : Polymer solar cells are promising in that they are inexpensive to produce, and due to their mechanical flexibility have the potential for use in applications not possible for more traditional types of solar cells. The performance of polymer solar cells depends strongly on the distribution of electron donor and acceptor material in the active layer. READ MORE

  5. 8. The plantaris tendon in relation to the Achilles tendon in midportion Achilles tendinopathy : studies on morphology, innervation and signalling substances

    Author : Christoph Spang; Sture Forsgren; Håkan Alfredson; Patrik Danielson; Karim Khan; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Plantaris tendon; Achilles tendon; Achilles tendinopathy; innervation; morphology;

    Abstract : Midportion Achilles tendinopathy (tendinosis) is a troublesome painful condition, often characterised by pain, local swelling, tenderness and functional disability. Despite extensive research, the pathogenesis is poorly understood and treatment remains challenging. Features related to the peritendinous connective tissue can be of importance. READ MORE

  6. 9. Heterogeneous Film-Forming Latexes : Preparation - Morphology - Mechanical Properties

    Author : Ola Karlsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; core-shell; particle morphology; heterogeneous latexes; particle size; crosslinking; hydrophilicity; poly isoprene-co-styrene-co-methacrylic acid ; monomer partitioning; internal particle viscosity; transmission electron microscopy TEM ; calorimetric reactor; two-stage; seeded emulsion polymerization; film morphology; mechanical properties; paper coating.; Polymer technology; biopolymers; Polymerteknik;

    Abstract : This thesis describes the preparation of heterogeneous latexes, which may serve as binders in coating applications, and the characterization of these. The latexes were prepared in two-stage seeded emulsion polymerization. READ MORE

  7. 10. Crystallinity and Morphology of Starch Polymers in Films

    Author : Åsa Rindlav Westling; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; morphology; amylose; surface; thermal transitions; amylopectin; starch; crystallinity; film;

    Abstract : Starch is a renewable material that can be converted into biodegradable plastic products, or films with excellent oxygen barrier properties. Films of potato starch, amylose, amylopectin and blends thereof were made by solution casting. READ MORE
