[1] Variations in ocean productivity are driven largely by nutrient supply to the photic zone, but temporal records of nutrient variability are sparse. Here we show scleractinian coral P/Ca proxy records of variations in phosphate concentrations during El Niño Southern Oscillation (ENSO) cycles in the central equatorial Pacific. Covarying P/Ca records in Porites corals from Christmas and Fanning Islands show a regional ~40% decrease during the upwelling relaxation of the 1997–1998 El Niño, consistent with less frequent nutrient measurements from this area. Similar ~35–45% skeletal P/Ca decreases occur during the 1982–1983 and 1986–1987 El Niño events, which predate satellite color …

The base-induced propargylation of the dye indigo results in the rapid and unprecedented one-pot synthesis of highly functionalized representatives of the pyrazino[1,2-a:4,3-a′]diindole, pyrido[1,2-a:3,4-b′]diindole and benzo[b]indolo[1,2-h]naphthyridine heterocyclic systems, with the last two reflecting the core skeleton of the anticancer/antiplasmodial marine natural products fascaplysin and homofascaplysins and a ring B-homologue, respectively. The polycyclic compounds 6–8, whose structures were confirmed through single-crystal X-ray crystallographic analysis, arise from sequential inter/intramolecular substitution–addition reactions, and in some cases, ring rearrangement reactions. Preliminary studies on controlling the reaction path selectivity, and the potential reaction mechanisms, are also described. Initial biological activity studies with these new heterocyclic derivatives …

Rates Of Shoreline Change Along The Coast Of Bangladesh, Md. Golam Mahabub Sarwar, Colin D. Woodroffe
Faculty of Science, Medicine and Health - Papers: part A
Bangladesh, at the confluence of the sediment-laden Ganges and Brahmaputra Rivers, supports an enormous and rapidly growing population (>140 million in 2011), across low-lying alluvial and delta plains that have accumulated over the past few thousand years. It has been identified as one of the most vulnerable places in the world to the impacts of climate change and sea-level rise. Although abundant sediment supply has resulted in accretion on some parts of the coast of Bangladesh, others are experiencing rapid erosion. We report a systematic assessment of rates of shoreline change over a 20-year period from 1989 to 2009, …
Concise Synthesis Of (-)-Steviamine And Analogues And Their Glycosidase Inhibitory Activities, Nadechanok Jiangseubchatveera, Marc E. Bouillon, Boonsom Liawruangrath, Saisunee Liawruangrath, Robert J. Nash, Stephen G. Pyne

A concise synthesis of (−)-steviamine is reported along with the synthesis of its analogues 10-nor-steviamine, 10-nor-ent-steviamine and 5-epi-ent-steviamine. These compounds were tested against twelve glycosidases (at 143 μg mL−1 concentrations) and were found to have in general poor inhibitory activity against most enzymes. The 10-nor analogues however, showed 50–54% inhibition of α-L-rhamnosidase from Penicillium decumbens while one of these, 10-nor-steviamine, showed 51% inhibition of N-acetyl-β-D-glucosaminidase (from Jack bean) at the same concentration (760 μM).

Faculty of Science, Medicine and Health - Papers: part A
UV-vis photodissociation action spectroscopy is becoming increasingly prevalent because of advances in, and commercial availability of, ion trapping technologies and tunable laser sources. This study outlines in detail an instrumental arrangement, combining a commercial ion-trap mass spectrometer and tunable nanosecond pulsed laser source, for performing fully automated photodissociation action spectroscopy on gas-phase ions. The components of the instrumentation are outlined, including the optical and electronic interfacing, in addition to the control software for automating the experiment and performing online analysis of the spectra. To demonstrate the utility of this ensemble, the photodissociation action spectra of 4-chloroanilinium, 4-bromoanilinium, and 4-iodoanilinium cations …
Switching Radical Stability By Ph-Induced Orbital Conversion, Ganna Gryn'ova, David L. Marshall, Stephen J. Blanksby, Michelle L. Coote
Switching Radical Stability By Ph-Induced Orbital Conversion, Ganna Gryn'ova, David L. Marshall, Stephen J. Blanksby, Michelle L. Coote
Faculty of Science, Medicine and Health - Papers: part A
In most radicals the singly occupied molecular orbital (SOMO) is the highest-energy occupied molecular orbital (HOMO); however, in a small number of reported compounds this is not the case. In the present work we expand significantly the scope of this phenomenon, known as SOMO–HOMO energy-level conversion, by showing that it occurs in virtually any distonic radical anion that contains a sufficiently stabilized radical (aminoxyl, peroxyl, aminyl) non-π-conjugated with a negative charge (carboxylate, phosphate, sulfate). Moreover, regular orbital order is restored on protonation of the anionic fragment, and hence the orbital configuration can be switched by pH. Most importantly, our theoretical …
Five Practical Uses Of Spatial Autocorrelation For Studies Of Coral Reef Ecology, S Hamylton
Five Practical Uses Of Spatial Autocorrelation For Studies Of Coral Reef Ecology, S Hamylton
Faculty of Science, Medicine and Health - Papers: part A
The organisation of benthic communities across coral reefs is underpinned by spatially structured ecological processes and neighbourhood interactions such as larval dispersal, migration, competition and the spread of disease. These give rise to spatial autocorrelation in reef communities. This paper demonstrates how the measurement of spatial autocorrelation can profitably be incorporated into studies of coral reef ecology through a series of 5 simple statistical exercises: for the generation of maps depicting the strength of spatial relationships between ecological communities, as an indicator of optimal dimensions for sampling ecological communities on coral reefs, as a diagnostic tool for model misspecification, as …

The development of cell printing is vital for establishing biofabrication approaches as clinically relevant tools. Achieving this requires bio-inks which must not only be easily printable, but also allow controllable and reproducible printing of cells. This review outlines the general principles and current progress and compares the advantages and challenges for the most widely used biofabrication techniques for printing cells: extrusion, laser, microvalve, inkjet and tissue fragment printing. It is expected that significant advances in cell printing will result from synergistic combinations of these techniques and lead to optimised resolution, throughput and the overall complexity of printed constructs.
Carbon Dioxide Rebreathing In Respiratory Protective Devices: Influence Of Speech And Work Rate In Full-Face Masks, Carmen L. Smith, Jane L. Whitelaw, Brian Davies
Carbon Dioxide Rebreathing In Respiratory Protective Devices: Influence Of Speech And Work Rate In Full-Face Masks, Carmen L. Smith, Jane L. Whitelaw, Brian Davies
Faculty of Science, Medicine and Health - Papers: part A
Carbon dioxide (CO2) rebreathing has been recognised as a concern regarding respirator use and is related to symptoms of discomfort, fatigue, dizziness, headache, muscular weakness and drowsiness. Previous investigations are limited by small sample size and have not evaluated the relationship between CO2 inhalation and phonic respiration (breathing during speech) in respiratory protective devices (RPDs). A total of 40 workers trained in the use of RPDs performed a graded exercise test on a cycle ergonometer that increased in workload every 5 min. During the third minute of each stage, participants read aloud a prepared text. Measures of mixed expired CO2 …

Diversifying Ethnicity In Australia's Population And Environment Debates, Natascha Klocker, Lesley Head
Faculty of Science, Medicine and Health - Papers: part A
Population–environment debates in Australia are at an impasse. While the ability of this continent to sustain more migrants has attracted persistent scrutiny, nuanced explorations of diverse migrant cultures and their engagements with Australian landscapes have scarcely begun. Yet as we face the challenges of a climate changing world we would undoubtedly benefit from the most varied knowledges we can muster. This paper brings together three arenas of environmental debate circulating in Australia—the immigration/carrying capacity debate, comparisons between Indigenous and Anglo-European modes of environmental interaction, and research on household sustainability dilemmas—to demonstrate the exclusionary tendencies of each. We then attempt to …

Welcome To Bogan-Ville: Reframing Class And Place Through Humour, Chris Gibson
Faculty of Science, Medicine and Health - Papers: part A
On August 4, 2009, Australian online news commentary website the Punch announced that Albion Park, in the Australian industrial city of Wollongong, was one of the nation's top ten “most bogan” places. This paper explores what it means to be bogan in Australia, tracing historical antecedents, local debate at the time of this media event, and the manner in which the politics of class and place identity are negotiated through humour. Some local residents railed against associations with “lower-class” culture or feared damaged reputations for their neighbourhoods; others responded in sometimes unexpected and creative ways—through humour, and by claiming bogan …

This report is the second in a series of companion papers describing the effects of atmospheric light scattering in observations of atmospheric carbon dioxide (CO2) by the Greenhouse gases Observing SATellite (GOSAT), in orbit since 23 January 2009. Here we summarize the retrievals from six previously published algorithms; retrieving column-averaged dry air mole fractions of CO2 (XCO2) during 22 months of operation of GOSAT from June 2009. First, we compare data products from each algorithm with ground-based remote sensing observations by Total Carbon Column Observing Network (TCCON). Our GOSAT-TCCON coincidence criteria select satellite observations within a 5° radius of 11 …
Dinosaur Lactation?, Paul L. Else
Dinosaur Lactation?, Paul L. Else
Faculty of Science, Medicine and Health - Papers: part A
Lactation is a process associated with mammals, yet a number of birds feed their newly hatched young on secretions analogous to the milk of mammals. These secretions are produced from various sections (crop organ, oesophageal lining and proventriculus) of the upper digestive tract and possess similar levels of fat and protein, as well as added carotenoids, antibodies and, in the case of pigeons and doves, epidermal growth factor. Parental care in avian species has been proposed to originate from dinosaurs. This study examines the possibility that some dinosaurs used secretory feeding to increase the rate of growth of their young, …

Sequential Extraction Procedures For The Determination Of Phosphorus Forms In Sediment, Changyou Wang, Yong Zhang, Hongli Li, R John Morrison
Faculty of Science, Medicine and Health - Papers: part A
This article summarizes the main extraction methods for sedimentary phosphorus (P) determination. With sequential chemical extractions, P is supposed to be selectively removed from different compounds in the sediments. Extraction schemes using strong acids and alkaline solutions have been tested on different sediments and found not to extract well-defined fractions. In addition, several systematic errors in these schemes have been detected. Thus, these schemes have been modified and simplified accordingly. The Standards Measurements and Testing Program of the European Commission (SMT) method is a popular modification of these extraction schemes, as it is simple to handle, allows laboratories to achieve …

Oligomers of the 40 and 42 residue amyloid-β peptides (Aβ40 and Aβ42) have been implicated in the neuronal damage and impaired cognitive function associated with Alzheimer’s disease. However, little is known about the specific mechanisms by which these misfolded species induce such detrimental effects on cells. In this work, we use single-molecule imaging techniques to examine the initial interactions between Aβ monomers and oligomers and the membranes of live cells. This highly sensitive method enables the visualization of individual Aβ species on the cell surface and characterization of their oligomerization state, all at biologically relevant, nanomolar concentrations. The results indicate …

CONTEXT: Maternal obesity is associated with high plasma triglyceride, poor vascular function, and an increased risk for pregnancy complications. In normal-weight pregnant women, higher triglyceride is associated with increased small, dense low-density lipoprotein (LDL). HYPOTHESIS: In obese pregnancy, increased plasma triglyceride concentrations result in triglyceride enrichment of very low-density lipoprotein-1 particles and formation of small dense LDL via lipoprotein lipase. DESIGN: Women (n = 55) of body mass index of 18-46 kg/m(2) were sampled longitudinally at 12, 26, and 35 weeks' gestation and 4 months postnatally. SETTING: Women were recruited at hospital antenatal appointments, and study visits were in a …

Food Synergy: The Key To A Healthy Diet, David R. Jacobs Jr, Linda C. Tapsell
Faculty of Science, Medicine and Health - Papers: part A
Food synergy is the concept that the non-random mixture of food constituents operates in concert for the life of the organism eaten and presumably for the life of the eater. Isolated nutrients have been extensively studied in well-designed, long-term, large randomised clinical trials, typically with null and sometimes with harmful effects. Therefore, although nutrient deficiency is a known phenomenon, serious for the sufferer, and curable by taking the isolated nutrient, the effect of isolated nutrients or other chemicals derived from food on chronic disease, when that chemical is not deficient, may not have the same beneficial effect. It appears that …
Synthesis, Characterization, And Photophysics Of Oxadiazole- And Diphenylaniline-Substituted Re(I) And Cu(I) Complexes, Raphael Horvath, Michael G. Fraser, Scott A. Cameron, Allan G. Blackman, Pawel Wagner, David L. Officer, Keith C. Gordon

Transition-metal complexes of the types [Re(CO)3Cl(NN)], [Re(CO)3py(NN)]+, and [Cu(PPh3)2(NN)]+, where NN = 4,4′-bis(5-phenyl-1,3,4-oxadiazol-2-yl)-2,2′-bipyridine (OX) and 4,4′-bis(N,N-diphenyl-4-[ethen-1-yl]-aniline)-2,2′-bipyridine (DPA), have been synthesized and characterized. Crystal structures for [Re(CO)3Cl(DPA)] and [Cu(PPh3)2(OX)]BF4 are presented. The crystal structure of the rhenium complex shows a trans arrangement of the ethylene groups, in agreement with density functional theory calculations. The structure of the copper complex displays the planar aromatic nature of the bpy–oxadiazole ligand. Density functional theory modeling of the complexes was supported by comparison of calculated and experimental normalized Raman spectra; the mean absolute deviations of the complexes were <10 cm–1. The Franck–Condon state was investigated using UV–vis and resonance Raman spectroscopic as well as density functional theory computational techniques. It was shown that the lowest energy absorption peaks are metal to ligand charge transfer and ligand-centered charge transfer for the oxadiazole- and diphenylaniline-substituted bipyridine ligands, respectively. The lowest energy excited states were characterized using transient emission and absorption spectroscopic techniques in conjunction with density functional theory calculations. These showed that the DPA complexes had ligand-centered nonemissive “dark” states with lifetimes ranging from 300 to 2000 ns.

Propargyl amines 4, where R3 is aryl, undergo 5-exo-dig cyclization reactions under relatively mild conditions (AgNO3, DMF, 60 °C, 1 h) to give 3-amino-2,3-dihydro-2-arylmethylidenebenzofurans 5 (R3 = aryl). In contrast, substrates where R3 is alkyl undergo competing 6-endo-dig and 5-exo-dig cyclization processes. The hydroxymethyl substrate 4 (R3 = CH2OH), however, was smoothly converted to its corresponding 5-exo-dig cyclization product 5, likely due to the assistance of the primary hydroxyl group in the 5-exo-dig cyclization process by silver cation coordination. Under more enforcing conditions (AgNO3, DMF, 100 °C, 18 h), the initially formed products 5 undergo a 1,3-allylic rearrangement to their …

Research on rare and threatened plants is a major focus of conservation biology. We want to know why species are rare or declining, how best to arrest that decline and what is lost when species become locally extinct. Occasionally, understanding decline is straightforward - e.g. if the species is restricted to fertile soils that are desirable for cultivation. However, managing declining populations is more complex and requires knowledge of genetic diversity and interspecific interactions.

Faculty of Science, Medicine and Health - Papers: part A
Background: At-risk drinking is common in Australia. Validated screening tools such as the AUDIT-C have been promoted to general practitioners (GPs), but appear rarely used and detection of at-risk drinking in primary care remains low. We sought to describe Australian GP perceptions of the detection and screening of at-risk drinking; to understand their low uptake of alcohol screening questionnaires, and in particular, their attitude to the adoption of the AUDIT-C. Methods. Semi-structured focus group interviews of four groups of GPs and GP trainees were conducted in metropolitan Sydney between August and October 2011. Audio recordings were transcribed and analysed using …

Atrial fibrillation (AF) is estimated to affect 1%-2% of the population. It is increasing in prevalence and is associated with excess mortality, considerable morbidity and hospitalisations. AF is responsible for a significant and growing societal financial burden. Catheter ablation is an increasingly used therapeutic strategy for the management of AF; however, some confusion exists among those caring for patients with this condition about the role and optimal use of ablative treatments for AF. Our aim in this consensus statement is to provide recommendations on the use of primary catheter ablation for AF in Australia, on the basis of current evidence. …

An environmental water releases to the Snowy River was made in October 2011 (12,000 ML/day) as part of the Snowy River Increased Flows Program. The effects on the inlet entrance morphology and tidal response were measured on four field trips for each release to cover the flow peak and recovery. Water level recorders were deployed in the principal channels over the period of the releases and for the prior two months at Marlo. The EFR raised waterlevels in the estuary but the change was attenuated by the large storage capacity and the relatively open entrance. Entrance scour was minor as …

Estimation of total leaf area (LAT) is important to express biochemical properties in plant ecology and remote sensing studies. A measurement of LAT is easy in broadleaf species, but it remains challenging in coniferous canopies. We proposed a new geometrical model to estimate Norway spruce LAT and compared its accuracy with other five published methods. Further, we assessed variability of the total to projected leaf area conversion factor (CF) within a crown and examined its implications for remotely sensed estimates of leaf chlorophyll content (Cab). We measured morphological and biochemical properties of three most recent needle age classes in three …
