    Abstract : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. READ MORE

  5. 3. Injection and Combustion of Alternative Fuels in Spark Ignited Direct Injection Engines

    Author : Lars Christian Riis Johansen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas fuel; direct injection; E85; stratified combustion; spark ignition; alternative fuels; optical measurements;

    Abstract : Increasingly stringent vehicle emission legislation necessitates increasingly efficient combustion engines. The use of direct injection in spark ignited engines improves engine efficiency and reduces CO2 emissions. READ MORE

  6. 4. Epidemiological studies of bioprosthetic aortic valves

    Author : Michael Dismorr; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: The use of bioprosthetic valves is common and offers a prosthetic option that does not require anti-coagulant therapy, but with shorter valve longevity compared to mechanical prostheses. Valve model selection might influence the long-term performance of the prosthesis. READ MORE

  7. 5. Effects of GH and liver-derived IGF-I on growth and metabolism

    Author : Klara Sjögren; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GH; IGF-I; Insulin; GHRH; Somatostatin; GHS; Body growth; Body composition; Liver; Bone mineral content; Bone mineral density.;

    Abstract : Growth hormone (GH) exerts major effects on body growth and metabolism. Insulin-like growth factor (IGF) is expressed in response to GH and is known to mediate many of the effects of GH. The largest expression of IGF is found in the liver although it is expressed in virtually every tissue of the body. READ MORE
