  1. 6. Gastrointestinal stromal tumors. Pathogenetic mechanisms, phenotypic characterization and prognosis

    Author : Johanna Andersson; Göteborgs universitet; []
    Keywords : Gastrointestinal stromal tumor GIST ; neurofibromatosis type I NF1 ; mutation; prognosis; denaturating high performance liquid chromatography dHPLC ; sequencing; KIT; PDGFRA; NF1;

    Abstract : Gastrointestinal stromal tumor (GIST), the most common non-epithelial neoplasm of the gastrointestinal tract, has historically been problematic both conceptually and clinically. Recently, GIST has been shown to share phenotypic features with the interstitial cells of Cajal (ICC), including the almost uniform expression of the tyrosine kinase receptor KIT. READ MORE

  2. 7. Structural Requirements for Selective DNA Binding - Studies on Mono- and Binuclear Ruthenium Complexes

    Author : Johanna Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ruthenium; enantioselectivity; sequence selectivity; spectroscopy; threading intercalation; calorimetry; kinetics; DNA; cell studies;

    Abstract : Ever since the discovery of the role of DNA as the template for protein synthesis, efforts have been made to develop DNA targeted drugs. One of the major challenges in the design of DNA binding drugs is to achieve selective binding to specific DNA sequences, which is crucial to avoid side effects. READ MORE

  3. 8. Surface tension-driven flow in soft porous materials — An investigation of the mechanism of capillary flow in microchannels of hydrogels

    Author : Johanna Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting on soft materials; Capillary flow; alginate gel; capillary action;

    Abstract : Spontaneous spreading of liquids in porous materials is of great industrial relevance and occurs in, for example, diapers, fabrics, paper or paint. Often, it is necessary to manipulate the spreading rate of liquids to result in the desired mass transport, for example to soak up large liquid volumes, as in a diaper. READ MORE

  4. 9. No environmental problem is an island : Aligning networks of transboundary collaboration to complex policy issue interdependencies

    Author : Johanna Hedlund; Örjan Bodin; Daniel Nohrstedt; Erik Andersson; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; complex environmental problems; policy issues; policy issue interdependencies; transboundary governance; networks; collaborative governance; policy issue interdependency networks; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : In recent times, societal and environmental problems have been exhibiting a growing interconnectedness and interdependency. Based on the idea of institutional fit, interdependency on a problem level should be preferably matched with governance arrangements for effective problem-solving. READ MORE

  5. 10. Assessment of Robustness in Railway Traffic Timetables

    Author : Emma V. Andersson; Jan Lundgren; Anders Peterson; Johanna Törnquist Krasemann; Thorsten Büker; Linköpings universitet; []
    Keywords : ;

    Abstract : A tendency seen for the last decades in many European railway networks is a growing demand for capacity. An increased number of operating trains has led to a delay sensitive system where it is hard to recover from delays, where even relatively small delays are easily propagating to other traffic.
