Single Event Upset at Ground Level

Ground level upsets have been observed in computer systems containing large amounts of random access memory (RAM). Atmospheric neutrons are most likely the major cause of the upsets based on measured data using the Weapons Neutron Research (WNR) neutron beam.

Ground Water Issue: Chemical Enhancements to Pump-and-Treat Remediation January 1992

Conventional pump-and-treat technologies are among the most widely used systems for the remediation of contaminated ground water. Within recent years it has become recognized that these systems can require protracted periods of time to make significant reductions in the quantity of contaminants associated with both the liquid and solid phases which constitute the subsurface matrix. Evaluating t...

Analysis 65 January 2005

Clark and Chalmers (1998) defend the view that the human mind need not be in the human head. To speak more carefully, they defend the view that the material vehicles 1 of cognition can be spread out across brain, body and certain aspects of the physical environment itself. Critics of this view (which has become known as the ‘extended mind hypothesis’, henceforth EM) have pointed to the supposed...

Acceleration of Relativistic Protons during the 20 January 2005 Flare and CME

The origin of relativistic solar protons during large flare/CME events has not been uniquely identified so far. We perform a detailed comparative analysis of the time profiles of relativistic protons detected by the worldwide network of neutron monitors at Earth with electromagnetic signatures of particle acceleration in the solar corona during the large particle event of 20 January 2005. The i...
