Stabilization of monolayers at the organic-aqueous interface by citrate protected Au nanoparticles is shown to affect the interfacial dynamics and this effect is manifested in the oscillations of the interfacial potential. Variation in the size and concentration of the nanoparticles systematically affects the oscillations, attributed to particle-induced stabilization of monolayers. A structural...

OBJECTIVES The use of escorts (chauffeurs and chaperones) while on duty in after-hours-house-call (AHHC) is one key protective option available to doctors in the service, and has been linked to low burnout and increased satisfaction in AHHC. This study aims to explore the patterns of engagement of escorts in Australian AHHC. METHOD This is a questionnaire-based, electronic survey of all 300 d...

A label-free method is developed to ratiometrically determine the stoichiometry of oligonucleotides attached to the surface of gold nanoparticle (GNP) by whispering gallery mode biosensing. Utilizing this scheme, it is furthermore shown that the stoichiometric ratio of GNP attached oligonucleotide species can be controlled by varying the concentration ratio of thiolated oligonucleotides that ar...

We report that the addition of alkali ions (sodium or potassium) to gold on KLTL-zeolite and mesoporous MCM-41 silica stabilizes mononuclear gold in Au-O(OH)x-(Na or K) ensembles. This single-site gold species is active for the low-temperature (<200°C) water-gas shift (WGS) reaction. Unexpectedly, gold is thus similar to platinum in creating -O linkages with more than eight alkali ions and esta...

In this research, WO3 and Au-WO3 thin films were prepared at different temperatures using the sol gel method. The effect of gold nanoparticles (GNPs) on the electrochromic properties of WO3 was also studied. 2.5 nm GNP was synthesized through sodium citrate reduction of gold chloride in an aqueous solution. These films were characterized by XRD, SEM, TEM, and spectrophotometer analyses. The fil...

Ten years ago I wrote a resource paper on “Discrete Choice Modeling for Transportation” for the 9 IATBR conference on the Gold Coast of Australia (Brownstone, 2001). While the scope of the resource paper for this conference is broader, it is still interesting to review the claims and recommendations made ten years ago to see how they have been received in our profession. The purpose of this pap...

INTRODUCTION The Frank Street catchment is an urbanised area on the Gold Coast located between Loders Creek and Biggera Creek, and drains directly to the Southport Broadwater. It has long been recognised that the capacity of drainage systems in the Frank Street area is minimal, primarily due to the aging drainage infrastructure. Most of the drainage systems were constructed prior to 1987 (when ...

The pilot study reported in this paper was devised to develop and compare service delivery models that would achieve the provision of high quality parenteral therapy care to patients in the Gold Coast District Health Service community. All data were collected on 113 patients for a 12-month period, January to December 1996. The study compared the provision of outreach nursing services and contra...

The recent association of a fatal human case of encephalitis with a newly identified lyssavirus apparently acquired from a native Australian bat has highlighted the possibility that previous human infections have passed urecognised. Infected bats have been identified on the Queensland Gold Coast where extensive close contact between bats and humans has occurred for many years. In an attempt to ...

Several HMGB1-specific antagonists have provided beneficial results in multiple models of inflammatory disease-preclinical trials including arthritis. Since no HMGB1-specific targeted therapy has yet reached the clinic, we have performed in vitro studies to investigate whether any of a selection of well-established antirheumatic drugs inhibit HMGB1 release as part of its mode of action. Freshly...
