Comparative studies of invasive plants: a leaf carbon strategy approach. Invasion of communities by exotic plants is a significant threat to biodiversity globally. This proposal is to strengthen collaborative links between the Plant Invasion Research Laboratories of Leishman in Australia and Richardson in South Africa. Their current research seeks to understand strategies of invasive plants in novel environments using the framework of leaf carbon strategies.

Invasion of communities by exotic plants is a significant threat to biodiversity globally. This proposal is to strengthen collaborative links between the Plant Invasion Research Laboratories of Leishman in Australia and Richardson in South Africa. Their current research seeks to understand strategies of invasive plants in novel environments using the framework of leaf carbon strategies. Australian plants invasive in South Africa and South African plants invasive in Australia provide an ideal model system. This collaborative research will enable better prediction of potential invaders, as well as providing important input for models of plant, ecosystem and biosphere responses to global change incorporating invasion dynamics.Read moreRead less
Microdynamic study of the flow of granular materials in bladed mixers. This project aims to develop a comprehensive understanding of granular mixing mechanics in bladed mixers. The study will be carried out by means of newly developed advanced numerical and experimental techniques to generate particle scale information. The flow and mixing behaviour of particles under different conditions will be analysed at both micro- and macro-scopic levels. The research outcomes such as predictive equations ....Microdynamic study of the flow of granular materials in bladed mixers. This project aims to develop a comprehensive understanding of granular mixing mechanics in bladed mixers. The study will be carried out by means of newly developed advanced numerical and experimental techniques to generate particle scale information. The flow and mixing behaviour of particles under different conditions will be analysed at both micro- and macro-scopic levels. The research outcomes such as predictive equations will be tested by simulating and analysing complicated industrial mixing processes; modelling to improve granulation and breakage will be targets. It will significantly improve the design, optimisation and control of mixing processes that are widely used in many industries.Read moreRead less
Particle scale studies of powder mixing in bladed mixers. Powder handling and processing are widely used in both conventional and modern industries but rarely reach more than 60% of design capacity because of poor fundamental understanding. Such operations are important to Australia in view of the heavy dependence on raw materials processing (about 40% of the GNP). This project will tackle the core problems in powder mixing which is a key operation in many industries. Application of the research ....Particle scale studies of powder mixing in bladed mixers. Powder handling and processing are widely used in both conventional and modern industries but rarely reach more than 60% of design capacity because of poor fundamental understanding. Such operations are important to Australia in view of the heavy dependence on raw materials processing (about 40% of the GNP). This project will tackle the core problems in powder mixing which is a key operation in many industries. Application of the research outcomes can lead to better process or product control, a decrease in energy consumption and an improvement in productivity, which is very helpful to maintaining Australia's leading position in resource, energy, process and allied industries.Read moreRead less
Development of an integrated methodology to assess dewatering system performance in solid-liquid separation. 3D visualisations of microstructures are possible with techniques such as confocal laser microscopy and high resolution X-ray microtomography. Data obtained in-situ enable direct computation of solids assembly properties and their permeability to fluids. A specific application involving aggregate formation and sediment networks could be evaluated through micro-scale analysis combined with ....Development of an integrated methodology to assess dewatering system performance in solid-liquid separation. 3D visualisations of microstructures are possible with techniques such as confocal laser microscopy and high resolution X-ray microtomography. Data obtained in-situ enable direct computation of solids assembly properties and their permeability to fluids. A specific application involving aggregate formation and sediment networks could be evaluated through micro-scale analysis combined with robust fluid flow simulations. The method can potentially be utilized to predict trends such as filtration behaviour of materials under different states of compression. This offers significant benefits in formulating the design of flocculated systems pertinent to a number of industrial sectors wishing to design optimum solid-liquid separation processes.Read moreRead less
Environmental quality and health in the elderly; The Australian situation and international comparison. The elderly are a vulnerable population group that should receive particular attention in health policy. They are a group of considerable and growing size that contributes disproportionately to total health burden. Although residential environment is likely to influence health and well-being among the elderly, the evidence-base for appropriate policy and practice is lacking. Improved understa ....Environmental quality and health in the elderly; The Australian situation and international comparison. The elderly are a vulnerable population group that should receive particular attention in health policy. They are a group of considerable and growing size that contributes disproportionately to total health burden. Although residential environment is likely to influence health and well-being among the elderly, the evidence-base for appropriate policy and practice is lacking. Improved understanding of the role of relevant environmental factors could lead to substantially reduced morbidity and mortality (and associated costs) for the key outcomes: falls, and cardiovascular and respiratory disease. Results will contribute to the international evidence-base in this increasingly critical area of research, policy, and practice. Read moreRead less

Aerially applied insecticides are used worldwide to control periodic locust infestations. Assessment of their effects on vertebrates is based on limited information concerning a few North American or European species. We will compare the sublethal effects of 3 compounds currently used or under consideration by the Australian Plague Locust Commission (APLC) on representative Australian vertebrates. Assessments include cholinesterase inhibition, peak aerobic performance , thermoregulatory ability, stress responses, immune function and feeding behaviour. Our collaboration includes expertise in comparative physiology, endocrinology and wildlife toxicology.Read moreRead less
