  2. 11. Fatty acid methyl esters as reactive diluents in solvent-borne thermally cured coil-coatings

    Author : Katarina Johansson; Mats Johansson; Mats Jonsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fatty acids; Reactive diluents; Coatings; Thermal curing; Transesterification; Film properties; Polymer chemistry; Polymerkemi;

    Abstract : This work describes how a fatty acid methyl ester (FAME) derived from a vegetable oil can be introduced as reactive diluent in a solvent-borne thermally cured coil-coating system. The evaluated reactive diluent, rape seed methyl ester (RME), has been evaluated both in a fully formulated clear coat system and via model studies. READ MORE

  4. 12. Thermally cured coil-coatings utilizing novel resins and fatty acid methyl esters as reactive diluents

    Author : Katarina Johansson; Mats Johansson; Rolf van Benthem; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coatings; Coil-coatings; Thermal cure; Reactive diluents; Fatty acids; Transesterification; Hyperbranched polyester resins; Film properties; Polymer chemistry; Polymerkemi;

    Abstract : Solvent-borne thermally cured coil-coating resins contain large amounts of volatile organic solvents in order to obtain suitable flow for film application. This work describes how the expensive and environmental hazardous volatile organic solvent content of a solvent-borne thermally cured polyester/melamine coil-coating system can be reduced by introduction of fatty acid methyl esters (FAMEs) as reactive diluents and modification of the polyester binder resin.

  5. 13. Epidemiology of venous thromboembolism with focus on risk markers

    Author : Magdalena Johansson; Lars Johansson; Marcus Lind; Jan-Håkan Jansson; Gerd Lärfars; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Venous thromboembolism; venous thrombosis; deep vein thrombosis; pulmonary embolism; incidence; risk markers; diabetes; glucose; alcohol consumption; alcohol dependence; physical activity; medicin; Medicine;

    Abstract : Background: Venous thromboembolism (VTE) is a vascular disease with an incidence of approximately 140 cases per 100,000 person-years in adults. The incidence of VTE has increased over the last decades, and more than 20% of affected individuals die in the first year after diagnosis. READ MORE

  6. 14. The circadian clock in annuals and perennials : coordination of Growth with Environmental Rhythms

    Author : Mikael Johansson; Maria E. Eriksson; Paul Devlin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; circadian clock; arabidopsis; populus; Molecular biology; Molekylärbiologi; Plant biotechnology; Växtbioteknik; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Abstract : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. READ MORE

  7. 15. Epiphytic lichen responses to nitrogen deposition

    Author : Otilia Johansson; Kristin Palmqvist; Johan Olofsson; Annika Nordin; Lars E Ericson; Peter Crittenden; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lichens; air pollution; nitrogen deposition; phosphorus; growth; chlorophyll a; boreal forest; field experiment; irrigation; carbon based secondary compounds; Lavar; luftföroreningar; alg; svamp; kväve; fosfor; skog; Terrestrial ecology; Terrestrisk ekologi; ekologisk botanik; Ecological Botany;

    Abstract : Nitrogen (N) deposition has increased globally over the last 150 years and further increase is predicted for the future. Nitrogen is an important nutrient for lichens, involved in many processes in both photobiont and mycobiont.  However, N can be a stressor, causing many lichens and lichen communities to disappear with increased deposition.
