We here present a Computational Fluid Dynamics (CFD) model performed with COMSOL Multiphysics® simulation software as part of a collaboration with the Polarized Target Research Group at the University of New Hampshire (http://nuclear.unh.edu/research/polarized-target-lab/). By coupling ... En savoir plus

In his seminal work, “A Chemical Basis for Morphogenesis,” Alan Turing proposed a mechanism for pattern formation in nature. Turing patterns occur in a broad range of natural systems, from desert vegetation to animal markings. Turing mechanisms have also been implicated in processes ... En savoir plus

HVDC electrodes are installed on HVDC transmission systems to provide a low resistance current return path during both monopolar and bipolar operation, using the earth and/or sea as the conductive medium. HVDC electrodes are in general less costly and have lower losses than dedicated ... En savoir plus

Microwave plasma sources with a resonant cavity have been widely used in microwave electrothermal thrusters as an electric propulsion device, in which free-floating plasma is ignited and sustained in a propellant gas. The resonant cavity microwave plasma has become increasingly ... En savoir plus

Cold season thunderstorms are a threat for wind turbines in several areas of the world because the thundercloud is much closer to the earth compared to warm season thunderstorms. As a consequence, the electric field between cloud and ground is much higher during these storms, triggering ... En savoir plus

Disciplines such as neutron polarimetry and medical imaging depend on highly uniform magnetic fields to preserve target polarization, and have turned to "magic boxes" to reliably generate these fields. Searches for the permanent Electric Dipole Moment of the neutron (nEDM) are sensitive ... En savoir plus

Granular and powdered activated carbons have been widely used for purification/filtration in air and water as catalysts or organic adsorbents. To obtain mechanical filtration capacity and inorganic reduction performance, activated carbon can be formed as a block-shaped porous media, ... En savoir plus

Cancer cells have an increased sensitivity to heat compared to healthy cells; at 42°C cancer cells are destroyed while normal cells can survive up to 47°C. Thus hyperthermia-based approaches that target specific spatial locations and simultaneously provide controlled thermal exposure ... En savoir plus
