It is expected that this will result in improved outcomes and fewer side-effects for radiotherapy patients.
The flotation of oxide minerals using hydroxamate collectors. Australian and world mineral resources are declining in quality as we exploit the richest sulfidic ore deposits. This is increasing our reliance on concentration and beneficiation processes to improve the economics of the selective recovery of minerals from lower grade and, increasingly, oxide or lateritic ore bodies. In addition, greater emphasis is being placed on our environmental stewardship and the need to remove hazardous mater ....The flotation of oxide minerals using hydroxamate collectors. Australian and world mineral resources are declining in quality as we exploit the richest sulfidic ore deposits. This is increasing our reliance on concentration and beneficiation processes to improve the economics of the selective recovery of minerals from lower grade and, increasingly, oxide or lateritic ore bodies. In addition, greater emphasis is being placed on our environmental stewardship and the need to remove hazardous material from the concentrate streams. This proposal will develop improved methods and techniques that will facilitate better, cleaner separations and recovery of the valuable oxide mineral components using Australian-developed flotation reagents.Read moreRead less

Most of Australia's 10 billion litre milk flow is converted to powder form for exports, with an annual value exceeding $1billion. The anticipated improvements in the performance and shelf-life of the dried dairy powder systems to be investigated in this project have the potential ....The Molecular Mechanism of Protein Instability in Dairy Powder Systems. Dairy is the fourth largest rural industry sectors in Australia, directly involving more than 13,000 farms and a large number of dairy factories. Most of Australia's 10 billion litre milk flow is converted to powder form for exports, with an annual value exceeding $1billion. The anticipated improvements in the performance and shelf-life of the dried dairy powder systems to be investigated in this project have the potential to generate significant economic impacts in both the dairy production and processing sectors. This work will also benefit the wider scientific community in dairy- and food-related areas, particularly in relation to the novel multidisciplinary approach involving a combination of material science and protein chemistry.Read moreRead less
Mapping the dark matter with early type galaxies. Unidentified dark matter outweighs luminous matter (stars, gas, and galaxies) by several times and is detected by its gravitational effects in the Universe. The Six Degree Field Galaxy Survey is now complete and this project will prepare a larger survey, which will put the team clearly in the lead in understanding the distribution of dark matter.
QUANTIFICATION OF INTERACTIONS DURING THE DISPERSION OF CORONA IONS AND AIRBORNE PARTICLES NEAR POWER LINES. Currently there is no method for quantification of concentration and dispersion of charged aerosols near high voltage power lines (HVPLs). However, hypothesis have been presented, but not yet proven scientifically, that residents of houses close to combustion sources such as highways or industrial plants and HVPLs may be subjected to health risk due to inhalation of charged aerosols. The ....QUANTIFICATION OF INTERACTIONS DURING THE DISPERSION OF CORONA IONS AND AIRBORNE PARTICLES NEAR POWER LINES. Currently there is no method for quantification of concentration and dispersion of charged aerosols near high voltage power lines (HVPLs). However, hypothesis have been presented, but not yet proven scientifically, that residents of houses close to combustion sources such as highways or industrial plants and HVPLs may be subjected to health risk due to inhalation of charged aerosols. The outcome of this project will be a model for quantitative assessment of the processes occurring during the transport and dispersion of corona ions and combustion aerosol, which will be a tool for predictive risk assessment and informed management of public resources in relation to power line design and maintenance.Read moreRead less

Fighting terrorism and crime is one of the most important and difficult tasks that requires substantial human and technological resources. This project will help to address this enormous problem by developing a new optical sensor technology for the detection and identification of traces of chemicals, explosives, drugs and biological agents. It will develop a laboratory prototype of this sensor that is expected to have superior sensitivity and operational capabilities. Thus it will noticeably contribute to practical law enforcement, air quality and environmental monitoring, counter-terrorism, air safety, border security and customs service. It will also lead to further development of nano-optics and nanotechnology in Australia. Read moreRead less

Severe-profound congenital hearing loss engenders significant costs to society. In 2005, specialised education cost -- on average $25,000 per child, loss of productivity cost -- $6.7 billion, and social security benefits were paid to approximately 129,000 individuals who were unemployed due to hearing loss. If bilateral cochlear implantation results in improved language, social development, and academic outcomes, the community benefits arising will be greatly improved quality of life for these individuals and significant savings to society. In partnership with Cochlear Ltd, this study will provide some of the first data worldwide comparing the effects of an additional implant on language, social and educational outcomes.Read moreRead less

Relationship between melanosome distribution and skin colour. This work seeks to examine how the colour of our skin is related to the distribution of melanosomes. This work may allow us to better understand how to develop novel therapies that may alter skin colour and provide protection from the sun (frontier technologies) but may also, in the longer term, lead to healthier approaches to skin management - especially for ageing skin.
