ObjectiveScrew loosening is a common complication following lumbar spine fixation surgery, yet the biomechanical outcomes after screw loosening remain rarely reported.This study aims to utilize finite element (FE) models to compare the biomechanical performance of PEEK rod dynamic fixation and titanium rod rigid fixation in the postoperative lumbar
The paper describes two different procedures to explain and to model the observed heave of a nuclear power plant founded on an expansive unsaturated claystone.In the initial model developed, the claystone was represented by a double structure (micro-macro) expansive clay.Field swelling records were accurately reproduced and the model was used to pr
The olive tree may be attacked by several insect pests, especially the black Scale, which is associated with this plant throughout its cycle, could limit the production due to leaf drop and poor fruit set.This study aims to evaluate the behavior toothbrush timer of the predatory stinkbug Podisus nigrispinus Dallas (Hemiptera: Pentatomidae) in olive
Abstract The importance of human resource for the success and growth of every organisation, including banks in developing economies, cannot be underestimated.The banking sector in Ghana, a developing economy, has recently faced some significant performance-related difficulties, such Sun Hats as suspending the licences of new banks, raising the mini
Gaussian boson sampling (GBS) is a quantum sampling task in which one has to draw samples from the photon-number distribution of a large-dimensional nonclassical squeezed state of light.In an effort to make this task intractable for a classical computer, experiments building GBS machines have mainly focused on increasing the dimensionality and sque
