    Sammanfattning : We have used the chicken retina as a model for investigating cell cycle regulation and cell fate commitment during central nervous system development. This thesis focuses on the characterization of and commitment to the horizontal cell fate in the retina. LÄS MER

  5. 4. Tailored layer-by-layer films of nanofibrillated cellulose

    Författare :Erdem Karabulut; Lars Wågberg; Lennart Piculell; Eva Blomberg; KTH; []
    Nyckelord :layer-by-layer assembly; nanofibrillated cellulose; thin film; surface adsorption; polyelectrolytes;

    Sammanfattning : The preparation of multifunctional films, coatings and membranes from natural, sustainable and low-cost raw materials has attracted considerable interest during the last decade. In this respect, cellulose-based products possess a great promise for research and industry due both to the availability of large amounts of material in nature and to the preparation of new classes of nano-sized and well-characterized building-blocks of cellulose from trees or annual plants.

  7. 5. Ozonskiktet och risksamhället : En studie av den svenska politiska diskussionen rörande ozonskiktet 1968-1992

    Författare :Mathias Martinsson; Jonas Anshelm; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ozone layer; ozone depletion; CFC; environmental politics; risk society; ecological modernisation; reflexive modernisation; political use of scientific knowledge; ozonskiktet; miljöaspekter; miljöpolitik; historia; Sverige; 1968-1992; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : This thesis examines the development of the Swedish political discussion concerning the ozonelayer between 1968 and 1992. The analysis is based on the assumption that the threats against the ozone layer confronted the political system with an issue that called for new ways of thinking about environmental problems.
