  1. 1. Printability and Ink-Coating Interactions in Inkjet Printing

    Författare :Erik Svanholm; Göran Ström; Gunnar Engström; Janet Preston; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; inkjet; print quality; printability; pigment; silica; polyvinyl alcohol; colorant; ink absorption; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. LÄS MER

  3. 2. Heterogeneous Film-Forming Latexes : Preparation - Morphology - Mechanical Properties

    Författare :Ola Karlsson; Fysikalisk kemi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Modification of flavonoid content and photosynthesis by ultraviolet-B radiation. Atrazine-tolerant and -sensitive ultivars of Brassica napus

    Författare :Louise Olsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; recovery; quercetin; photosynthesis; photoinhibition; photoacoustics; leaf anatomy; kaempferol; flavonoid; D1 protein; fluorescence; cold stress; carbon dioxide; atrazine tolerance; Brassica napus; UV-B; Physiological biophysics; Växtfysiologi;

    Sammanfattning : Levels of ultraviolet-B (UV-B, 280-320 nm) radiation reaching the Earth´s surface increase due to stratospheric ozone depletion. In this thesis the effect of enhanced UV-B radiation was studied on the atrazine-tolerant mutant Stallion, susceptible to photoinhibition, and the atrazine-sensitive cultivar Paroll of Brassica napus (oilseed rape).

  5. 4. Effect of virulence factors on survival strategies of vibrio cholerae and vibrio mimicus

    Författare :Soni Priya Valeru; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vibrio cholerae;

    Sammanfattning : Vibrio is a genus of gram-negative bacteria comprising nearly 70 species and they are clinically human pathogens that can cause many infections. This study is mainly based on two species such as Vibrio cholerae O1 El Tor, which cause cholera disease and Vibrio mimicus, that cause gastroenteritis, open wounds infection, and septicemia.

  7. 5. Effects of increased UV-B radiation on the lichen Cladonia arbuscula spp. mitis: UV-absorbing pigments and DNA damage

    Författare :Roberta Buffoni Hall; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Systematic botany; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; kemotaxonomi. Växters fysiologi inte kärlväxter .; Systematisk botanik; taxonomi; morfologi;

    Sammanfattning : Lichens, a form of symbiosis between a fungal and a photosynthetic partner, are believed to be a group that evolved early in the history of terrestrial life. As a consequence, they probably experienced higher ultraviolet (UV) radiation fluxes than at present. LÄS MER
