    Sammanfattning : The geological disposal of nuclear waste, in underground openings and the long-term performance of these openings demand a detailed understanding of fundamental rock mechanics. A full scale field experiment: Äspö Pillar Stability Experiment was conducted at a depth of 450 m in sparsely fractured granitic rock to examine the rock mass response between two deposition holes.

    Sammanfattning : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry due to major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the vehicle’s weight while increasing engine's efficiency. LÄS MER

  7. 5. The Entheses of the Medial Meniscns and Ligaments of the Knee Joint : Descriptive and Experimental Studies

    Författare :Jizong Gao; Michael Benjamin; Linköpings universitet; []
    Nyckelord :knee joint; meniscus; ligaments; insertion; enthesis; quantitative morphology; fibrocartilage; cement line; collagens; proteoglycans; nerve fibres; tensile strength; failure mode; transection; refixation; repair; healing; osteoarthrosis; histology; immunohistochemistry; biomechanics; rabbit model; MEDICINE; MEDICIN;

    Sammanfattning : Meniscal injuries are common in sports. Surgical removal of the meniscus to relieve symptoms is associated with a high risk for late knee joint osteoarthrosis and pain. Meniscal repair or replacement has therefore been advocated. LÄS MER
