  1. 1. Synthesis of degradable aliphatic polyesters: strategies to tailor the polymer microstructure

    Författare :Jenny Fagerland; Anna Finne-Wistrand; David Kaplan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer synthesis; enzymatic synthesis; degradable polyesters; peptides; scaffolds; Chemical Engineering; Kemiteknik;

    Sammanfattning : Key factors for successful tissue engineering are the synthesis and design of the scaffold materials. Aliphatic polyesters have been studied and often used as scaffold materials for tissue engineering. However, their lack of biological cues and degradation under high-temperature processing (e.g. LÄS MER

    Sammanfattning : This thesis introduces new ways to produce micro-and nanostructures of recombinant spider silk and explores ways to characterize their topography, mechanical properties, cell compatibility, and permeability. The suitability of the formed structures for applications within tissue engineering, primarily in vitro tissue modeling, is also investigated. LÄS MER

  4. 3. Re-establishment of connectivity for fish populations in regulated rivers

    Författare :Olle Calles; Larry Greenberg; Lars Nyberg; David Scruton; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Attraction efficiency; Connectivity; Flow regime; Hyporheic water quality; Nature-like fishway; Passage efficiency; Regulated river; Remedial measures; Salmo trutta; Biology; Biologi; Biology; Biologi;

    Sammanfattning : The hydropower industry has altered connectivity in many rivers during the last century. Many fish species depend on both an intact longitudinal connectivity to be able to migrate between spawning, feeding and winter habitats, and vertical connectivity for development and survival of incubating embryos and larvae in the gravel.
