Intelligent and objective measurement of wool fibre diameter. More than a half million tones of wool produced in Australia per year are visually evaluated by human woolclassers. This fibre-classing process is subjective and heavily dependent on the experience of the classers. In this project, we will objectively measure wool fibre diameter by extracting features used by human woolclassers and by combining image processing and artificial intelligence. The fractal dimension calculated by fracta ....Intelligent and objective measurement of wool fibre diameter. More than a half million tones of wool produced in Australia per year are visually evaluated by human woolclassers. This fibre-classing process is subjective and heavily dependent on the experience of the classers. In this project, we will objectively measure wool fibre diameter by extracting features used by human woolclassers and by combining image processing and artificial intelligence. The fractal dimension calculated by fractal based texture analysis will be correlated to fibre diameter. This approach will provide an insight into an on farm and/or in shed objective measurement of wool fibre diameter.Read moreRead less
Brain temperature regulation in mammals: mechanisms and consequences. Mammals detect increases in body temperature predominantly in the brain. Counterintuitively many mammals selectively cool the brain during heat stress, which appears to defeat the mechanism for inducing cooling responses. We intend to investigate this apparent anomaly which we believe is concerned with optimizing water use in hot conditions. We will further investigate the source of water for evaporative cooling by panting and ....Brain temperature regulation in mammals: mechanisms and consequences. Mammals detect increases in body temperature predominantly in the brain. Counterintuitively many mammals selectively cool the brain during heat stress, which appears to defeat the mechanism for inducing cooling responses. We intend to investigate this apparent anomaly which we believe is concerned with optimizing water use in hot conditions. We will further investigate the source of water for evaporative cooling by panting and discover if there has been convergent evolution in thermoregulatory strategies in the eutherian and marsupial lineages. The data we collect will be used to support a new model for thermoregulation in mammals.

Reassessing the role of industry associations through an examination of Australian and New Zealand wool marketing, 1890-1960. This is a study of organisational innovation in an internationally-important industry. Wool industry associations built and maintained a marketing organization, regionally and then nationally, that sold more than a half of the world's wool. Our long-term study assesses whether associations along the supply chain could replenish their social capital and remain adaptive and ....Reassessing the role of industry associations through an examination of Australian and New Zealand wool marketing, 1890-1960. This is a study of organisational innovation in an internationally-important industry. Wool industry associations built and maintained a marketing organization, regionally and then nationally, that sold more than a half of the world's wool. Our long-term study assesses whether associations along the supply chain could replenish their social capital and remain adaptive and flexible organisations in the face of marked changes in the environment. The nature of the web of connections between associations in the wool market deserves further study. If their cooperation made possible the institutions governing wool selling then government agencies may need to take a more nuanced approach to regulating inter-organizational collaboration.Read moreRead less
The Molecular Basis of Copper Metabolism in Sheep. The unusual copper metabolism of sheep represents a significant agricultural problem. They are very susceptible to copper deficiency, but readily accumulate copper to toxic levels in the liver leading to fatal liver failure. We propose to elucidate the reason for the copper accumulation phenotype of sheep. We are focussing on WND, a copper transporter responsible for copper excretion into bile. We discovered a novel form of sheep WND designated ....The Molecular Basis of Copper Metabolism in Sheep. The unusual copper metabolism of sheep represents a significant agricultural problem. They are very susceptible to copper deficiency, but readily accumulate copper to toxic levels in the liver leading to fatal liver failure. We propose to elucidate the reason for the copper accumulation phenotype of sheep. We are focussing on WND, a copper transporter responsible for copper excretion into bile. We discovered a novel form of sheep WND designated WNDb to distinguish it from the normal form, WNDa. The experiments outlined are designed to understand the function of both proteins in the sheep and their role in copper sequestration.Read moreRead less
Pathogenesis, regulation and genomics of the ovine footrot pathogen, Dichelobacter nodosus. Footrot is one of the most economically significant diseases of sheep in Australia. The aim of this project is to develop a detailed understanding of how the bacterium that causes this infection is able to infect the sheep hoof and result in clinical disease. The complete sequence of the genome of the causative bacterium will be determined, enabling us to deduce its genetic potential. The completed projec ....Pathogenesis, regulation and genomics of the ovine footrot pathogen, Dichelobacter nodosus. Footrot is one of the most economically significant diseases of sheep in Australia. The aim of this project is to develop a detailed understanding of how the bacterium that causes this infection is able to infect the sheep hoof and result in clinical disease. The complete sequence of the genome of the causative bacterium will be determined, enabling us to deduce its genetic potential. The completed project will significantly advance fundamental knowledge of the disease process and will lead to the development of improved methods for the control of the disease, with concomitant cost savings to Australian primary industry.Read moreRead less
Protein Fibre Powders: Production, Characterisation and Applications. Australia leads the world in the production of protein fibres such as wool. Traditionally, these fibres are used primarily for textile related applications, which have been increasingly relying on the much cheaper synthetic fibres. The outcome from this research will be very significant in that it will underpin the future development of a sustainable protein fibre industry, through value-added and high-end applications. It wil ....Protein Fibre Powders: Production, Characterisation and Applications. Australia leads the world in the production of protein fibres such as wool.

The outcome from this research will be very significant in that it will underpin the future development of a sustainable protein fibre industry, through value-added and high-end applications. It will further strengthen our world leading position in the production, characterisation and application of protein powder materials.Read moreRead less
Functional genomics of large clostridial plasmids. The aims of this genomics project are to determine how large DNA elements called plasmids are able to be transferred between different strains of a bacterium that causes disease in domestic livestock. These plasmids carry genes that encode the potent protein toxins that are responsible for several diseases. To understand how these diseases are spread we must learn how the plasmids have evolved and whether they can move from bacterium to bacteriu ....Functional genomics of large clostridial plasmids.

These plasmids carry genes that encode the potent protein toxins that are responsible for several diseases. To understand how these diseases are spread we must learn how the plasmids have evolved and whether they can move from bacterium to bacterium. The successful completion of the project will result in a detailed understanding of genetic elements that are important mediators of several diseases of importance to Australian primary industry.Read moreRead less
