    Abstract : Two numerical models for simulation of concrete cracking and bond slip have been implemented and applied in various comparative analyses. Both models were implemented in the commercial finite element system ABAQUS. READ MORE

  4. 4. Impairment of Endothelial Thromboprotective Function by Haemodynamic and Inflammatory Stress - Implications for hypertensive disease

    University dissertation from Chalmers University of Technology

    Author : Erik Ulfhammer; Göteborgs universitet.; Gothenburg University.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tissue-type plasminogen activator; endothelium; fibrinolysis; hypertension; shear stress; strain; antihypertensive agents; inflammation; TNF-alpha; NF-kappaB; MAPK;

    Abstract : The physiologically most important activator of intravascular fibrinolysis is tissue-type plasminogen activator (t-PA). The endothelium synthesizes and stores t-PA and regulated release of the enzyme is an important local protective response to prevent thrombus extension. READ MORE

  5. 5. Ultrastructural Aspects of Pulp Fibers as Studied by Dynamic FT-IR Spectroscopy

    University dissertation from Stockholm : Fiber- och polymerteknologi

    Author : Margaretha Åkerholm; KTH.; [2003]
    Keywords : cellulose; cooperation; crystallinity; dynamic test; glucomannan; hardwood; holocellulose; humidity; infrared spectroscopy; kraft pulp; lignin; mechanical pulp; orientation; polarised light; softwood; strain; sulphite pulp; viscoelasticity; xylan;

    Abstract : Dynamic (or 2D) FT-IR spectroscopy in combination withpolarized IR irradiation has been used in this work to studywood polymer orientation and interactions on theultrastructural level in wood fibers in the native state aswell as the effects of different pulping processes. The woodpolymer interactions were studied under both dry and humidconditions. READ MORE
