Managing The Acidity Of Abandoned Water Filled Coal Mining Voids In Collie (Western Australia) Using Organic Matter, Scott A. Thompson
Managing The Acidity Of Abandoned Water Filled Coal Mining Voids In Collie (Western Australia) Using Organic Matter, Scott A. Thompson
Theses: Doctorates and Masters
The effectiveness of using organic matter additions to increase pH in abandoned water filled coal mining voids in Collie was investigated. Previous studies have demonstrated that passing acidic drainage through organic matter increased the waters pH. Laboratory trials using intact sediment cores (collected from Ewington, Collie, Western Australia) were used to assess the effects of additions of hay, manure and mulched vegetation on pH, nutrients an sulphate levels. In a series of experiments the effect of different quantities of organic material, sulphate reducing bacterial inoculations and alkalinity generation were measured. A subsequent field experiment was conducted to examine the impact …
An Investigation Of The Relationship Between Organisational Size And Industry Type With The Development And Use Of Executive Information Systems In The Manufacturing Sector, Nigel Warne
Theses: Doctorates and Masters
The purpose of this investigative research is to provide quantitative detail to better understand the development and use of Executive Information Sysytems (EIS) in the Australian Manufacturing sector. This investigation is an extension of previous research done on EIS in Australia (Prevan, 1992; Pervan and Phua, 1997) and looks more closely at the independent variables of organisation size and industry type in their relationaship with the development and use of EIS. A broad literature review provides a descriptive model that gives some insight into the development and use of EIS over more than fifteen years. Over eighty per cent of …
