    Abstract : The potential for recycling various polymeric materials contained within buildings constructed in the late 1960s and 1970s in Sweden was investigated during the course of this work. Three residential blocks were studied to establish the quantity of materials available for recycling, to investigate the difficulty in and time needed for the dismantling of the buildings, the degree of purity of the materials, and the possibility of separating the materials.

  4. 7. Biomedical Applications of Bacterial Cellulose Fermentation, Morphology and Surface Properties

    Author : Aase Katarina Bodin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocompatibility; xyloglucan epitopes; mechanical properties; cell adhesion; tubular fermentation; morphology; Bacterial cellulose; surface properties; meniscus mold; crystal formation.; ozonation; adsorption;

    Abstract : Because average life expectancy has increased and peoples lifestyles have changed, degenerative diseases have become a critical issue. The demand for biomedical materials to replace or improve major body systems (skeletal, circulatory and nervous, etc.) will increase as people strive to maintain good quality of life. READ MORE
