The ionospheric storm evolution process was monitored during the 22 September 1999 magnetic storm over the Australian eastern region, through measurements of the ionospheric Total Electron Content (TEC) from seven Global Positioning Systems (GPS) stations. The spatial and temporal variations of the ionosphere were analysed as a time series of TEC maps.(More)
The effects of the 31 March 2001 severe magnetic storm on the Southern Hemisphere ionosphere have been studied using ground-based and satellite measurements. The prime goal of this comprehensive study is to track the ionospheric response from high-to-low latitude to obtain a clear understanding of storm-time ionospheric change. The study uses a combination(More)

Foods are complex systems exhibiting various degrees of elasticity, viscosity, and plasticity. Because of its complex structure and mechanical behavior, objective measurements of food texture may be influenced by a variety of test conditions, including rate of loading, the magnitude of deformations imposed upon the material, geometry of the loading surface,(More)
This paper describes the experimental procedures of tomographic imaging techniques that have been developed and used at La Trobe University. Tomographic imaging provides a powerful technique for obtaining images of the ionospheric electron density distribution, and is a relatively new technique which has promising features to supplement the most expensive(More)
With the recent advent of Global Positioning System (GPS) satellites as a research tool in studying the ionised regions that surround the Earth, a need has arisen for a simple yet accurate model for the plasmasphere, the region above the ionosphere. A model based on diffuse equilibrium has been developed, which is combined with the International Reference(More)
Seven patients who presented to hospital later than 10 h following an overdose of paracetamol were treated by charcoal hemoperfusion. In all cases there was a rapid fall in the plasma paracetamol concentrations, although the total amounts of drug removed varied from 364.5 to 6699 mg. One patient developed fulminant hepatic failure and died; the remainder(More)
