    Abstract : Plastics are extremely diverse in terms of chemical composition, properties and possible applications, and are widely distributed in the society and the environment. In the last 15 years the global annual production has doubled, reaching 245 million tons in 2008. READ MORE

  2. 2. In vitro and in vivo studies of tissue engineering in reconstructive plastic surgery

    Author : Fredrik R.M. Huss; Gunnar Kratz; Elof Eriksson; Fredrik Huss; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue engineering; plastic surgery; guided tissue regeneration; Plastic surgery; Plastikkirurgi; Plastikkirurgi; Plastic Surgery;

    Abstract : To correct, improve, and maintain tissues, and their functions, are common denominators in tissue engineering and reconstructive plastic surgery. This can be achieved by using autolo-gous tissues as in flaps or transplants. However, often autologous tissue is not useable. READ MORE

  3. 3. Chemical Pollutants Released to the Marine Environment by Degradation of Plastic Debris

  5. 5. Plastic Deformation of Duplex Stainless Steel

    Author : Magnus Nyström; Chalmers University of Technology; []
    Keywords : stainless steel; microstructure; plastic zones; impact toughness; anisotropy; prestraining; annealing; fractography; fatigue;

    Abstract : Duplex austenitic/ferritic stainless steels are increasingly used as an alternative to conventional austenitic grades. Main advantages of the duplex grades are good resistance to corrosion cracking and corrosion fatigue in environments that contain chloride. READ MORE
