The Projected Impact Of Rising Sea Levels On Real Property Right: An Australian Evaluation, John Sheehan, Lynne Armitage

Lynne Armitage

The predicted rise in sea level and associated increasing storm action over the next half century is colliding with settled property law for tidal properties much of which is held on the Australian coast in private ownership. Faster change to the climate is reported with more serious risk than anticipated, with implications for sea level rise now expected at the upper end of projections by the Intergovernmental Panel on Climate Change (IPCC) of around 0.8m by 2100 along the Australian coastline.

In response to the threat of sea level rise, the six Australian States have attempted to provide information to …

3d Single-Walled Carbon Nanotube Networks Encased In Crosslinked Polymer Monolayers: Toward Robust Nanotube Aerogels, Kevin Ausman, Andrew Adams, Lawanya Ojha, Maxim Tchoul, Krishna Bastola

Kevin D. Ausman

A thin, uniform coating of a polymer can suspend single-walled carbon nanotubes in water. The polymer coating is stabilized by the hydrophobic effect. Upon crosslinking this system under dilute conditions, the polymer sheath becomes stable to changes in solvent system. Upon crosslinking the system under semi-dilute conditions, robust three-dimensional networks are formed. Progress toward generating aerogels from these monolayer-coated nanotubes is reported.

C60 Oxide As A Key Component Of Aqueous C60 Colloidal Suspensions, Kevin Ausman, Befrika Murdianti, Joshua Damron, Martha Hilburn, Randall Maples, Rangika Hikkaduwa Koralege, Satish Kuriyavar

Kevin D. Ausman

The [6,6]-closed epoxide derivative (C60O) of buckminsterfullerene (C60) is found to stabilize aqueous fullerene colloidal suspensions (nC60). This pervasive derivative is often unrecognized, but present in small quantities in nearly all C60 starting materials due to a reaction with air. In nC60 formation from organic solvent solutions, C60O partitions preferentially to the colloid, significantly enriching the C60O content of the particles relative to the starting material. Because this partitioning is significantly retarded in nC60 synthesis methods that do not use organic solvents, such as long-term stirring in water, such methods instead rely on trace levels of ozone in the ambient …

Integrated Mathematica™-Based Physical Chemistry Curriculum: Bringing The Science To The Forefront, Kevin Ausman

Kevin D. Ausman

Undergraduate- and graduate-level physical chemistry classes are often so mathematically intensive that they often (a) dissuade qualified students from pursuing the field, (b) require more homework, testing, and grading time be devoted to tracking down hidden mathematical errors than is devoted to working with the subject matter, and (c) limit the complexity, and therefore real-world applicability, of assigned problems. In this talk, the integration of the general-purpose mathematical tool MathematicaTM throughout the second semester of undergraduate physical chemistry will be discussed. Examples provided will demonstrate the feasibility of introducing the MathematicaTM language gradually over the course of the semester, allowing …

Reference Interval Studies: What Is The Maximum Number Of Samples Recommended?, Robert Hawkins, Tony Badrick

Tony Badrick

Background: Little attention has been paid to the maximum number of specimens for reference interval calculation, i.e., the number of specimens beyond which there is no further benefit in reference interval calculation. We present a model for the estimation of the maximum number of specimens for reference interval studies based on setting the 90% confidence interval of the reference limits to be equal to the analyte reporting interval. Methods: Equations describing the bounds on the upper and lower 90% confidence intervals for logarithmically transformed and untransformed data were derived and applied to determine the maximum number of specimens required to …

The Effects Of Increasing Salinity On Exchange Processes In Coastal Lowland Acid Sulfate Soils, Vanessa Wong, Scott Johnston, Richard Bush, Leigh Sullivan, Edward Burton, Peter Slavich

Associate Professor Edward D Burton

10 coastal lowland acid sulfate soils (CLASS) from floodplains in eastern Australia were subjected to increasing seawater concentrations to determine the effects of exchange processes on metal desorption due to increasing ionic strength. Soils were subjected to one of six treatments; 0%, 10%, 20%, 50%, 80% or 100% seawater diluted in deionised water. pH decreased with increasing seawater concentration. In general, concentrations of Al, Cd, Fe2+ and Mn increased in soils sampled from levees, organic and mineral sulfuric horizons with increasing salinity. Increasing trace metal concentrations with increasing seawater concentration is attributed to both exchange processes and pH effects. The …

Harry Potter And The Myriad Mothers: The Maternal Figure As Lioness, Witch And Wardrobe, Kimberley Mcmahon-Coleman, Roslyn Weaver

Kimberley McMahon-Coleman

Families are important in the Harry Potter series. Harry's loss of his parents is a key focal point of the narrative, and the series is bookended by scenes that focus on family. Book One begins with Harry's placement as a baby into the Dursley family environment-the opening sentence of the series setting up the issue of families, normality, and belonging-while Book Seven concludes with a scene about the adult Harry's own family with his wife and children. A particular recurring theme is Harry's mother's love that protects and sustains him as he endures many trials and adventures. In this respect, …

Characterisation Of Porous Freeze Dried Conducting Carbon Nanotube-Chitosan Scaffolds, Simon Moulton, Gordon Wallace, Luke Sweetman

Luke Sweetman

In this study, the fabrication and characterisation of highly porous yet conductive scaffolds was performed. The conductive component, namely single-walled carbon nanotubes (SWNTs), was incorporated into a chitosan bio-polymeric matrix utilising a dispersion-based freeze dry approach. The electroactive polymer poly(2-methoxy-5-sulfonic acid) (PMAS) was also successfully incorporated into scaffolds in an effort to improve the structural integrity of scaffolds in an aqueous, biologically relevant environment. Here, we report how the variation in dispersion and scaffold synthesis conditions, as well as the composition of constituent components, impact on scaffold properties.

Suitability Of Membrane Bioreactor For Treatment Of Recalcitrant Textile Dye Wastewater Utilising White-Rot Fungi, Faisal Hai, Kazuo Yamamoto

Faisal I Hai

The performance of a laboratory scale membrane bioreactor (MBR) — utilizing a mixed microbial community dominated by fungi— for treatment of textile dye wastewater was investigated. A synthetic wastewater containing dye, starch (main contributor to total organic carbon, TOC) and other nutrients was used. Preliminary batch tests confirmed the superior decoloration capacity of pure fungus culture (Coriolus versicolor, NBRC 9791) as compared to that of conventional activated sludge. Simultaneous biosorption and biodegradation was evident in case of the fungus, while mainly biosorption was responsible for decoloration by activated sludge. On the other hand, activated sludge demonstrated comparatively faster TOC removal. …

Local Knowledge And The State: The 1990 Floods In Cunnamulla, Queensland, Australia, Emily O'Gorman

Emily O'Gorman

In April 1990, record-breaking floods in the Warrego River threatened the rural town of Cunnamulla, located in Queensland, Australia. The floods had already inundated the upstream town of Charleville causing significant damage to property and the mass evacuation of residents. This article explores the 1990 floods in Cunnamulla in the context of two key elements of Australian history: first, several decades of rural decline in southwestern Queensland, and second, state responses to floods that had become increasingly centralized over the preceding two decades. I first examine the wider historical contexts of colonial settlement, environmental changes, and past floods in Cunnamulla …
