We use data from the plasma and energetic particle instruments on Juno spacecraft, JADE JEDI, to study equatorial pitch angle distributions of protons within Jupiter's inner magnetosphere during Juno's prime mission 2016 2021. Averaging over all observations made by M-shell bins between M = 6 30, we find at energies 10 50 keV are predominantly field-aligned M-shells. In contrast, those above 20...

orthodontic miniscrews are widely used as temporary anchorage devices to facilitate orthodontic movements. miniscrew loosening is a common problem, which usually occurs during the first two weeks of treatment. macrodesign can affect the stability of a miniscrew by changing its diameter, length, thread pitch, thread shape, tapering angle and so on. in this study, a 3-d finite element analysis wa...

AbstractThe Darrieus turbine is used as an ocean current converter to generate renewable electrical energy. One way improve performance determine the optimal pitch angle. Therefore, purpose of this study was angle NACA 0018 airfoil with variations -6°, -2°, 0° and 2°. Numerical method help Ansy Fluent software carried out for construction turbine. The result research that 2° produces largest co...

Application of nanofluid and coiled tubes are two passive methods for increasing the heat transfer. In the present study, the turbulent flows of water and nanofluid in coiled tubes heat exchanger were numerically studied. CuO-water nanofluid containing 1 vol% copper oxide nanoparticles was used and single-phase approach was considered for nanofluid flow. The effect of different geometrical para...
