A new dynamic neutralisation system for lumbar spine segments has been developed and tested on four cadaveric lumbar spines. Segments L4/5 (3 cases) and L3/4 (1 case) were tested on a new lumbar spine simulator which allowed the simultaneous application of bending moments, compressive and shear loads. The average applied loads were 18.3 Nm flexion moment,(More)
This study presents a comparison of denitrification rates and denitrification stoichiometry when using different sources of carbon. Denitrification tests were carried out in test bottles containing water and soil samples acquired at a nitrate-contaminated site and supplemented with either sucrose, acetate or ethanol. The tests demonstrated nitrate removal(More)
