    Sammanfattning : Through 270 million years of evolution, the finely tuned hierarchical structure of wood has been optimized for efficient nutrient transport and exceptional mechanical stability. Its distinctive orthotropic constitution can provide inspiration and design opportunities for the development of novel functional materials. LÄS MER

  3. 2. Chemical Communication and Mate Choice : Investigations into the Meaning of a Fruit Fly Pheromone

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Drosophila grimshawi; sexual selection; pheromone; mate choice; lekking; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Chemical signals are the most widely used form of sexual communication throughout the living world. However, there is in general little knowledge about what these signals actually communicate. The role of chemical signals, i.e. LÄS MER

  4. 3. Making sense of Baltic democracy : public support and political representation in nationalising states

    Författare :Kjetil Duvold; Sten Berglund; Lars Johannsen; Paul G. Lewis; Örebro universitet; []

    Sammanfattning : A chief topic of this book is the advance of democracy in Estonia, Latvia and Lithuania. The three countries belong to the most ‘successful’ cases of transition from communist rule to democracy, demonstrated by the fact that they joined the European Union in 2004. LÄS MER

  5. 4. SAR studies of Capsazepinoid Bronchodilators The B-ring and the C-region

    Författare :Magnus Berglund; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; bronchodilator; Capsazepine; structure activity relationship;

    Sammanfattning : Capsazepine and similar compounds, capsazepinoids, were shown to be general inhibitors of agonist (leukotriene D4, histamine, acetylcholine, prostaglandin D2) evoked constriction of human small airway preparations. The mechanism of action remains to be elucidated, but established bronchodilator principles, e.g. LÄS MER

  7. 5. The threat from non indigenous species - ecosystem vulnerability, global distribution and co-occurrence with other major threats

    Författare :Helena Berglund; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; threats; distribution range; isolation; endemism; invasions; invaders; vulnerability; non indigenous species; rarity; threatened species;

    Sammanfattning : We live in a globalised world where people and goods travel large distances. Various species are brought along on these journeys, intentionally or as hitchhikers. Some of these species establish populations in regions to which they could not have spread without human assistance, and where they are considered to be non indigenous species (NIS). LÄS MER
