Smart management of disinfectant in chloraminated water-supply systems. This project aims to develop an adaptive, real-time control system for managing disinfectant residuals in chloraminated water supply systems. While chloramine delivers microbiologically safe drinking water in warmer climates and in long distribution systems, it is largely unpredictable, costs water utilities millions of dollars annually, and has uncertain benefits. This project’s control system will be guided by quantitative models formulated from multi-pronged, fundamental experiments. The project will quantify microbial chloramine decay and determine mechanisms to increase predictability. The project will develop and demonstrate a real-time control technology which delivered microbiologically safe, cost-efficient drinking water to people in warmer climates, despite warming climate and increasing population.Read moreRead less

Summary
Inconsistent quality of farmed barramundi (pond or recirculation system) in the marketplace has been identified by ABFA as a major issue causing buyer resistance and negative market impacts. This is limiting realisation of full revenue return for farmed barramundi. The inconsistency in quality is mainly associated with the presence of ‘earthy’ or ’muddy’ taints derived from planktonic and benthic algae (particularly cyanobacteria), fungi and actinomycetes which are known to p ....Inconsistent quality of farmed barramundi (pond or recirculation system) in the marketplace has been identified by ABFA as a major issue causing buyer resistance and negative market impacts. This is limiting realisation of full revenue return for farmed barramundi. The inconsistency in quality is mainly associated with the presence of ‘earthy’ or ’muddy’ taints derived from planktonic and benthic algae (particularly cyanobacteria), fungi and actinomycetes which are known to produce geosmin (GSM) and 2-methyl isoborneol (MIB). These compounds impart muddy, earthy, musty odour, detectable by the human palate when present at extremely low concentrations in water and fish, and not favoured by consumers (Percival et al., 2008). This project aims to develop an algae-taint production model for recirculation systems. This innovative approach will provide clear and measurable direction for reducing taint compound levels through provision of a practical management tool. Its use will significantly improve knowledge of the balance between water quality, algicide use and purging time and conditions, and taint variability.Read moreRead less

This project aims to assess the risk of low rates of mixing in sub-tropical drinking water supply reservoirs, using environmental monitoring and numerical modelling. Emerging evidence suggests sub-tropical drinking water supply reservoirs could transition to low mixing states with increasing age and projected changes in global climate. While this risk is poorly understood, it could significantly affect the long-term reliability of water supply and potable water treatment costs. Addressing this knowledge gap is expected to develop effective management responses to ensure the long term sustainable use of these water resources.Read moreRead less

Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely collected in Australia's catchments and thereby better predict water quality behaviour. Proposed field studies aim to support this development. The outcomes sought are improved planning and management of water quality in our rivers, lakes and estuaries, improved health of these water bodies and improved water supplies.Read moreRead less
Changing your mind by changing your brain: An interventionist perspective on cognitive neuroscience. Functional neuroimaging provides a tremendous amount of information about the brain, but what it shows about the mind is less clear.

Functional neuroimaging provides a tremendous amount of information about the brain, but what it shows about the mind is less clear. Addressing this fundamental philosophical question requires developing a detailed account of theory-testing in cognitive neuroscience. This project aims to connect neuroimaging to theories of explanation that focus on the way one variable can make a difference to another. By linking neuroimaging to facts about manipulable relationships between the brain and the mind, it will also provide a bridge between neuroimaging and complementary technologies for directly intervening on the brain. This, in turn, will provide a platform from which to explore the theoretical and ethical consequences of direct brain manipulation.Read moreRead less

Significant revenue loss for farmed prawns within the retail sector occurs through product not meeting market colour specification and also severe price reduction near the end of chilled storage life. The losses can be minimised by optimising on-farm production protocols to maintain a consistent colour in farmed prawns during frozen storage and by gaining additional shelf-life of chilled cooked prawns throughout the supply chain.
The opportunity is to introduce a range of technologies, along with widely-adopted proven best practise, that maintains premium quality after cooking and freezing. The technologies will incorporate natural compounds with antimicrobial/antioxidant properties, synergistic packaging, glazing and thereby extend chilled storage-life of the prawn whilst maintaining optimal quality. By maximising astaxanthin level at harvest and reducing degradation during storage, consistent premium red-orange colour of prawns will be assured for the retail market.
This research addresses the Program 3: Improving Farmed Prawn Market Value priority of APFA’s Five Year R&D Plan for the Australian Prawn Farming Industry, 2007-2012. Program 3 seeks to achieve the objective of increasing the average price received for Australian farmed prawns to $16.50/kg.
Objectives: 1. Evaluate the effectiveness of natural extracts as preservation technologies for reducing microbial loads 2. Compare various packaging options which are available commercially and select the most appropriate for synergistic extension storage life and to develop ready-to-go concept products 3. Develop optimised on-farm processing protocols by combining the most suitable natural compounds and packaging to obtain premium quality prawns 4. Summarise current available information on world-wide best practice operations that maximise red colour in cooked prawns 5. Determine rate of astaxanthin loss during processing and frozen storage 6. Establish required astaxanthin level in harvested prawns to retain colour level (APFA 8+) through subsequent long-term frozen storage 7. Identify synergistic benefits of a combination of techniques, including live harvest holding (black tank) and optimal glazing methods on astaxanthin levels and colour retention 8. Extend and illustrate optimal protocols to the industry partners through on-farm trials Read moreRead less
