  1. 1. The Dynamics of Innovation and Knowledge-Based Regional Development

    Författare :Peter Svensson; Magnus Klofsten; Per-Olof Brehmer; Dylan Jones-Evans; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation process; dynamics; knowledge-based regional development; social networks; entrepreneurship; Business and economics; Ekonomi;

    Sammanfattning : Geographical regions as diverse as Silicon Valley, California and Linköping, Sweden have been the sources of new technology and endogenously created innovations. Scholars and policymakers recognise that specific regions or clusters of businesses have the capability to engage in more innovative activities and new business formation and to experience higher employment growth than others.

  3. 2. Rectal cancer : the influence of surgical technique on morbidity, mortality and survival

    Författare :Petrus Boström; Martin Rutegård; Markku Haapamäki; Peter Matthiessen; Jörgen Rutegård; Martyn Evans; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rectal cancer; anterior resection; high ligation; level of tie; anastomotic leakage; postoperative pain;

    Sammanfattning : Surgery is still the most common treatment for rectal cancer, being the most effective and cost-efficient modality. However, it is not without risk, nor without controversies. LÄS MER

  4. 3. Alpha-2 Adrenergic Receptors and Signal Transduction : Effector Output in Relation to G-Protein Coupling and Signalling Cross-Talk

    Författare :Johnny Näsman; Peter Evans; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; Adrenergic; receptor; G-protein; adenylyl cyclase; cAMP; calcium; cross-talk; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : The alpha-2 adrenergic receptor (α2-AR) subfamily includes three different subtypes, α2A-, α2B- and α2C-AR, all believed to exert their function through heterotrimeric Gi/o-proteins. The present study was undertaken in order to investigate subtype differences in terms of cellular response and to explore other potential signalling pathways of α2-ARs. LÄS MER

  5. 4. Enhancing UV-protection of clear coated wood by utilizing reactive UV-absorber and epoxyfunctionalized soybean oil

    Författare :Sara Olsson; Mats KG Johansson; Emma Östmark; Mats Westin; Philip Evans; Minna Hakkarainen; Peter Weissenborn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UV-protaction; wood; clear coating; UV absorber; epoxy functionalized soybean oil; grafting;

    Sammanfattning : This work presents the development of a new pretreatment for clear coated wood, that aims to increase the photoprotection of exterior wood products, and at the same time make the system more environmentally friendly. The pretreatment comprises the reactive UV absorber 2-hydroxy-4(2,3-epoxy­propoxy)-benzophenone (HEPBP), which has a primary epoxy group that can be covalently attached to the hydroxyl groups of the wood substrate.

  7. 5. Distribution and actions of insect tachykinin-related peptides

    Författare :Åsa Winther; Peter D. Evans; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Insects; Insekter;

    Sammanfattning : Tachykinin-related peptides (TRPs) have been identified in a number of invertebrates belonging to the mollusca, euchiurdea, crustacea and insecta. The TRPs are named after their sequence similarities and possible common evolutionary relationship to the vertebrate tachykinins. LÄS MER
