This document provides guidelines for preparing manuscripts from the 35 th COSPAR assembly for publication in Advances in Space Research. These instructions are similar to the standard Elsevier manuscript preparation instructions, which can be downloaded from the Elsevier author gateway http://authors.elsevier.com. The general instructions are to prepare(More)
The geophysical significance of the thin nitrate-rich layers that have been found in both Arctic and Antarctic firn and ice cores, dating from the period 1561-1991, is examined in detail. It is shown that variations of meteorological origin dominate the record until the snow has consolidated to high-density firn some 30 years after deposition. The thin(More)
A total of 125 large fluence solar proton events identified from the nitrate deposition in ice core from Greenland for the period 1561-1950 are examined in an exploratory study of the geophysical information that will be available from such data in the future. These data have been augmented with ionospheric and satellite data for the up to 8 times more(More)

Wheelchair users are at high risk for developing repetitive stress injuries (RSI) of the cervical spine and glenohumeral joints due to increased demands on active range of motion (AROM) when performing functional tasks from a seated position. The addition of a seat elevation device may alleviate the risk factors that lead to the development of RSI. However,(More)
In recent years, there has been much debate surrounding the purpose and desirable out comes for higher education. This debate is illustrated in the different metaphors academics use to describe and makes sense of higher education. The goal of this study was to gain more insight into how college students understand higher education, and if their perceptions(More)
The global network of ground based neutron monitors and muon telescopes constitutes a unique " instrument " in an armada of particle detection and measurement facilities now in space and to be deployed in the future. This network has a particle energy detection threshold of order 500 MeV, extending up to 50 GeV, with a full-sky field of view continuously(More)
The Solar Radiation Alert (SRA) system continuously evaluates measurements of high-energy protons made by instruments on GOES satellites. If the measurements indicate a substantial elevation of effective dose rates at aircraft flight altitudes, the Civil Aerospace Medical Institute issues an SRA via the National Oceanic and Atmospheric Administration(More)
