Is the extreme phosphate sensitivity found among Australian plants a consequence of their adaptation to a severely phosphate-limited environment? The phosphorus (P)-impoverished soils of south-western Australia have allowed the evolution of many plants that are amazingly efficient at retrieving P from dying tissues. This project will contribute to the understanding of the mechanism determining P efficiency and will contribute significantly to the development of crops that are less reliant on non ....Is the extreme phosphate sensitivity found among Australian plants a consequence of their adaptation to a severely phosphate-limited environment?

The Identification Of Thoracic Targets For Prevention And Intervention In Bronchopulmonary Dysplasia

Summary
The persistence of breathing problems from infancy to later life is a complication of premature birth with lifelong consequences. Breathing problems often occur together with lung disease, but prematurity can also affect heart and blood vessel development, and weakness of the main breathing muscle. We will find out how much the heart, lungs and diaphragm contribute to breathing problems in babies; helping us to better predict, diagnose and treat severe breathing problems in babies born preterm.
Do Exposures Before Conception Influence The Risk Of Asthma In Offspring?

National Health and Medical Research Council
Funding Amount
$688,586.00
Summary
Asthma and poor lung function are major causes of public health issues. Emerging evidence suggests adverse exposures even before the conception of a child may cause these conditions. The proposed project is part of an international study across generations to identify these factors. This study will provide novel evidence to guide interventions and identify studies to advance this area further. These original findings will be of great importance both nationally and internationally.
CCC method: new applications to electron scattering from atoms and molecules. Achievement of the stated aims will be of enormous benefit to industry
and laboratory research because at the present time no reliably accurate
models exist for the range of the required scattering parameters. The
modelling work will result in development of new software packages for
supercomputers and will provide training for research associates, PhD
and Honours students in an area where Australian theorists are ....CCC method: new applications to electron scattering from atoms and molecules. Achievement of the stated aims will be of enormous benefit to industry

Summary
Ultra High Resolution Electron Recycling Spectrometer. Electron collisions with atoms and molecules provide enormous versatility through the transfer of large amounts of angular momentum and the ability to excite dipole forbidden states. However a lack of energy resolution severely restricts the processes that can be studied.
We propose to construct a unique, ultra-high resolution, electron recycling spectrometer using a radical new design.

Electron collisions with atoms and molecules provide enormous versatility through the transfer of large amounts of angular momentum and the ability to excite dipole forbidden states. However a lack of energy resolution severely restricts the processes that can be studied.
We propose to construct a unique, ultra-high resolution, electron recycling spectrometer using a radical new design. State-of-the-art spectroscopic studies of atoms and molecules will be enabled, including the dynamics of near-threshold processes, the formation of transient states and the examination of processes such as rotational excitation and dissociative attachment in molecules - important in a number of gas-discharge based devices.

These range from the fundamental problems of electron- or proton-impact ionisation of hydrogen through to collisions involving targets of interest to astrophysics, fusion, X-ray lasers and the lighting industry. The theory will also be extended to atom-surface interactions. The understanding of collisions between atomic particles and surfaces will support emerging fields of nanoscience and quantum computing.
