Low frequency resistive instability in a dusty Hall thruster plasma
, 2017 Along with crossed electric and magnetic fields in a Hall thruster, a radial component of electric field is generated that takes ions toward the walls, which causes sputtering and produces dust contamination in the thruster plasma. Considering negatively

Design and Simulation of a Miniature Hall-Effect Thruster
, 2018 Hall-Effect Thrusters are one of the simpler designs of modern Electric Propulsion (EP) systems, with one of the highest efficiency rates. They use a crossed electric and magnetic field to generate the known Hall current from which the device derives its

Digital Rights Activism in Multilevel Governance
European Policy Analysis, EarlyView.ABSTRACT Multilevel governance (MLG) without a clear hierarchical structure can create power imbalances among various actors, particularly in settings with overlapping jurisdictions and policy areas. This dynamic is especially pronounced in Internet governance, which faces a complex interplay of domestic laws, state interdependence, and heightened ...

Health Economics, EarlyView.ABSTRACT Economic policy can be a powerful instrument to influence food environments and support improved diets and health. Over the past 20 years, the use of fiscal policy to improve diets has increased dramatically. This paper reviews the trajectory of policy change, and explores the ways in which research has informed three different dimensions of ...
