Silence, Absence, And Mystery In Linda Hogan's Mean Spirit, Solar Storms, And Power
<p>In Mean Spirit, Solar Storms, and Power, Linda Hogan uses the devices of silence, absence, and mystery to articulate the oppression and marginalization of Native Americans. Specifically, because of the environmental crises that produce conflict in each novel, the project benefits from …

Quantification of Effect of Solar Storms on TEC over U.S. sector Using Machine Learning
A study of large solar storms in the equinox periods of solar cycles 23 and 24 is presented to quantify their effects on the total electron content (TEC) in the ionosphere. We study the dependence of TEC over the contiguous US on various storm parameters, including the onset time of the storm, the …

THE CATASTROPHIC OPEN WOUND: THE APPLICATION OF COMPLEX POST-TRAUMATIC STRESS DISORDER IN LINDA HOGAN’S SOLAR STORMS AND EDEN ROBINSON’S MONKEY BEACH
… of several characters in Linda Hogan’s <em>Solar Storms</em> and Eden Robinson’s <em>Monkey Beach</em>. The analysis first employs the two authors’ Native American ideas of trauma and then adds Herman’s theory of CPTSD to help bridge the gap between the Native American and Western cultures …

Caution Light: The Anik E2 Solar Disruption And Its Effect On Telesat Canada
… Anik line. On January 20, 1994, a major solar storm knocked out communications on two Anik satellites. Anik E1 was recovered through a backup system within hours. However, Anik E2 was non-operational until June 31, 1994, when engineers used an innovative ground fix to regain control.</p> …

Geomagnetically induced currents and their effect on power systems
… to power grids around the world. For example, solar storms that generate coronal mass ejections can induce a change in the Earth’s magnetic field. Geomagnetically induced current (GIC) then enters the power grid and causes unusual real and reactive power flows, voltage fluctuations, frequency …

Radiation of VLF/ELF waves from a magnetospheric tether
… of the Van Allen belts coming from cosmic rays, solar storms, high altitude nuclear explosions (HANEs) and other processes represent a significant danger to humans and spacecraft operating in those regions, as well as an obstacle to exploration and development of space technologies. The …

Controlled precipitation of energetic Van Allen belt protons by electromagnetic ion cyclotron (EMIC) waves : scientific and engineering implications
… belt traps highly energetic protons sourced from solar storms, cosmic rays and other processes. These particles can rapidly damage the space systems orbiting the inner region, limiting access to Low Earth Orbit (LEO). Decades of modeling and observations, however, show that naturally generated …

Saturation Effects in 3p3L Power Transformers due to Geomagnetically Induced Currents
… induced currents (GIC's) caused by solar storms or other sources of dc excitation can impact the normal operation of power transformers in transmission networks. The impact is caused by the dc current introduced into the windings of a transformer energised with ac, which leads to a …

Measurements and finite element modelling of transformer flux with dc and power frequency current
… induced currents (GIC’s) caused by solar storms or other sources of dc excitation in the presence of ac energization can disturb the normal operation of power transformers. If large enough, they cause half-cycle saturation of a power transformer’s core which could lead to overheating …

Long-term investigation of the lunar tide in the equatorial electrojet during stratospheric sudden warmings
… near-Earth space is not under the influence of solar storms, these processes become important drivers for ionospheric variability. Studying the link between these processes in the lower atmosphere and the ionospheric variability is important for our understanding of fundamental mechanisms in …
