Hydro-mechanical interactions in coal geo-sequestration of carbon dioxide. One of the most critical environmental issues facing society is that of global warming because of increasing concentrations of carbon dioxide released from burning of fossil fuels. Storage of CO2 in the ground, geo-sequestration, offers the promise of significant reductions in atmospheric CO2 release, particularly from coal fired power stations which produce 40% of Australia's CO2 emissions. The proposed project will lead ....Hydro-mechanical interactions in coal geo-sequestration of carbon dioxide. One of the most critical environmental issues facing society is that of global warming because of increasing concentrations of carbon dioxide released from burning of fossil fuels. Storage of CO2 in the ground, geo-sequestration, offers the promise of significant reductions in atmospheric CO2 release, particularly from coal fired power stations which produce 40% of Australia's CO2 emissions. The proposed project will lead to greater understanding and reduced risks during the injection and storage of CO2 in deep unmineable coal deposits. This will contribute to national efforts to reduce global warming, safeguard the Australian coal industry, and allow continued electricity generation from coal-fired plants. Read moreRead less

The project aims to discover the strategies by which cells in the brain interact with each other to code the sensory input efficiently. It is expected that simultaneous recording of the activity of many neurones from the visual cortex of anaesthetised cats during visual stimulation will reveal how the biophysics of synaptic integration combined with excitatory and inhibitory inputs from different sources sculpts the output of individual neurones. The experiments will be extended to the study of possible interactions between different areas of the brain and the study of mechanisms by which the cortical network and higher cognitive factors such as attention and memory might influence the coding of sensory information in awake animals.Read moreRead less
