    In this study we examined the impact of weather variability and tides on the transmission of Barmah Forest virus (BFV) disease and developed a weather-based forecasting model for BFV disease in the Gladstone region, Australia. We used seasonal autoregressive integrated moving-average (SARIMA) models to determine the contribution of weather variables to BFV transmission after the time-series data of response and explanatory variables were made stationary through seasonal differencing. We obtained data on the monthly counts of BFV cases, weather variables (e.g., mean minimum and maximum temperature, total rainfall, and mean relative humidity), high and low tides, and the population size in the Gladstone region between January 1992 and December 2001 from the Queensland Department of Health, Australian Bureau of Meteorology, Queensland Department of Transport, and Australian Bureau of Statistics, respectively. The SARIMA model shows that the 5-month moving average of minimum temperature (β = 0.15, p-value < 0.001) was statistically significantly and positively associated with BFV disease, whereas high tide in the current month (β = −1.03, p-value = 0.04) was statistically significantly and inversely associated with it. However, no significant association was found for other variables. These results may be applied to forecast the occurrence of BFV disease and to use public health resources in BFV control and prevention. PMID:16675420

    In January 2006, 25 tonnes of heavy fuel oil spilled into the Port of Gladstone in Queensland, Australia, from the breached hull of a bulk carrier ship. While approximately 18 tonnes of the oil was recovered, a certain amount of oil was deposited in the intertidal areas of Port Curtis leaving a highly visible, viscous residue. The objectives of this research were to assess the short-term (one month post-spill) and medium-term (six months post-spill) impacts on the intertidal habitat. Sediment polycyclic aromatic hydrocarbons (PAHs) and metal concentrations, mangrove communities and intertidal macroinvertebrates were assessed at oil impacted sites, adjacent sites which were not visibly impacted and reference sites which were located outside the recorded distribution of the oil spill. At one month post-spill, highest PAH concentrations were found at the impacted sites, with concentrations of some PAHs exceeding Australian and New Zealand sediment quality guidelines (SQG) [ANZECC/ARMCANZ, 2000. Sediment Quality Guidelines. Australia and New Zealand Environment and Conservation Council and Agriculture and Resource Management Council of Australia and New Zealand]. However, by six months post-spill PAH concentrations had significantly decreased. PAH concentrations tended to be higher in the back (upper) intertidal zone than at the front of the mangrove stand, and sediment cores indicated that PAH contaminants had remained in the top 4cm of the sediment. These results indicate that the overall decreased PAH concentrations are likely to be due to evaporation, photoxidation and tidal flushing of the residual oil in these impacted sites. During the initial survey, the impact site contained very few or no crabholes in the high intertidal area, indicating a low crab density in comparison to reference sites. However, at six months post-spill mangrove crab communities appeared to be fully recovered with crabhole densities in impact sites similar to reference sites. While little

    In January 2006, 25 tonnes of heavy fuel oil spilled into the Port of Gladstone in Queensland, Australia, from the breached hull of a bulk carrier ship. Over the following days, approximately 18 tonnes of the oil was recovered, however a certain amount of oil was deposited in the intertidal areas of Port Curtis leaving a highly visible, viscous residue. The objectives of this research were to assess the immediate impacts on the intertidal habitat and to gain baseline information for future comparative assessments. Sediment PAH and metal concentrations, mangrove communities and intertidal macroinvertebrates were assessed within one month post-spill at oil-impacted sites; adjacent sites which were not visibly impacted; and reference sites which were located outside the recorded distribution of the oil spill. Highest PAH concentrations were found at the impacted sites, with concentrations of some PAHs exceeding Australian and New Zealand Sediment Quality Guidelines (ANZECC/ARMCANZ, 2000). These sites contained very few or no crab holes in the high intertidal area, indicating a low crab density in comparison to reference sites. Little immediate impact was evident on the mangrove and macrobenthic communities, however future surveys may show evidence of longer-term impacts on these communities.

    The impact of anthropogenic factors arising from point and non-point pollution sources at a multi commodity marine port and its surrounding ecosystems were studied using sediment samples collected from a number of onshore (Gladstone Harbour and Facing Island) and offshore (Heron Island and Fitzroy Reefs) sites in Australia's Central Queensland. Sediment samples were analyzed for trace metals, organic carbon, polycyclic aromatic hydrocarbons (PAH), emerging chemicals of concern (ECC) and sterols. Similarly, the biological and biochemical interaction between the reef and its environment was analyzed by the multi-omic tools of next-generation sequencing characterization of the bacterial community and microbial community metabolic profiling. Overall, the trace elements were observed at the lower end of the Australian environmental guideline values at the offshore sites, while higher values were observed for the onshore locations Nickel and copper were observed above the high trigger value threshold at the onshore sites. The levels of PAH were below limits of detection across all sites. However, some of the ECC and sterols were observed at higher concentrations at both onshore and offshore locations, notably, the cholesterol family sterols and 17α-ethynylestradiol. Multi-omic analyses also indicated possible thermal and photo irradiation stressors on the bacterial communities at all the tested sites. The observed populations of γ-proteobacteria were found in combination with an increased pool of fatty acids that indicate fatty acid synthesis and utilisation of the intermediates of the shikimate pathways. This study demonstrates the value of applying a multi-omics approach for ecological assessments, in which a more detailed assessment of physical and chemical contaminants and their impact on the community bacterial biome is obtained.

    The Gladstone-Dale constant, which relates the refractive index to density, was measured for CF4 by counting fringes of a two-beam interferometer, one beam of which passes through a cell containing the test gas. The experimental approach and sources of systematic and imprecision errors are discussed. The constant for CF4 was measured at several wavelengths in the visible region of the spectrum. A value of 0.122 cu cm/g with an uncertainty of plus or minus 0.001 cu cm/g was determined for use in the visible region. A procedure for noting the departure of the gas density from the ideal-gas law is discussed.

    The smallest continent and one of the largest countries, Australia is a country of diverse geographical conditions and differing cultures of people unified by one predominant language and political system. Mountains, desert and rivers are some of the varying landscape features of Australia, although the climate and condition for most of the country is tropical. Original Australians, a hunting-gathering people called Aborigines, came to Australia over 38,000 years ago. Today the Aborigines compose about 1% of the population and live in traditional tribal areas as well as cities. The 1st European settlement came in 1788 from Great Britain. After World War II, the population doubled. Although the population is primarily composed of British and Irish immigrants, immigrants from other European countries such as Italy and Greece as well as refugees from Indochina, Vietnam, Cambodia and Laos are a significant factor to the growing Australian population. Australian and Aboriginal culture has took hold and took notice in the areas of opera, art, literature and film. The Australian Commonwealth is based on a constitution similar to that of the United States government. The National Parliament is bicameral with both the Senate and the House of Representatives having a select number of elected officials from each state and territory. The Australian economy is predominantly reliant on the sale of mineral and agricultural exports. History, economic changes, defense, international relations and notes to the traveler are also discussed in this overview of Australia.

  11. Australia's lithospheric density field, and its isostatic equilibration

    Density is a key driver of tectonic processes, but it is a difficult property to define well in the lithosphere because the gravity method is non-unique, and because converting to density from seismic velocity models, themselves non-unique, is also highly uncertain. Here we use a new approach to define the lithospheric density field of Australia, covering from 100°E to 165°E, from 5°N to 55°S and from the crust surface to 300 km depth. A reference model was derived primarily from the recently released Australian Seismological Reference Model, and refined further using additional models of sedimentary basin thickness and crustal thickness. A novel form of finite-element method based deterministic gravity inversion was applied in geodetic coordinates, implemented within the open-source escript modelling environment. Three spatial resolutions were modelled: half-, quarter- and eighth-degree in latitude and longitude, with vertical resolutions of 5, 2.5 and 1.25 km, respectively. Parameter sweeps for the key inversion regularization parameters show that parameter selection is not scale dependent. The sweep results also show that finer resolutions are more sensitive to the uppermost crust, but less sensitive to the mid- to lower-crust and uppermost mantle than lower resolutions. All resolutions show similar sensitivity below about 100 km depth. The final density model shows that Australia's lithospheric density field is strongly layered but also has large lateral density contrasts at all depths. Within the continental crust, the structure of the middle and lower crust differs significantly from the crystalline upper crust, suggesting that the tectonic processes or events preserved in the deep crust differ from those preserved in the shallower crust. The lithospheric mantle structure is not extensively modified from the reference model, but the results reinforce the systematic difference between the density of the oceanic and continental domains, and help identify

  12. Origin of north Queensland Cenozoic volcanism: Relationships to long lava flow basaltic fields, Australia

    Sutherland, F. L.

    1998-11-01

    A plume model proposed for north Queensland late Cenozoic volcanism and long lava flow distribution combines basalt ages with recent seismic studies of Australia's mantle, regional stress fields, and plate motion. Several basalt fields overlie mantle "thermal" anomalies, and other fields outside these anomalies can be traced to them through past lithospheric motion. Elsewhere, anomalies close to Australia's eastern rift margin show little volcanism, probably due to gravity-enhanced compression. Since final collision of north Queensland with New Guinea, areas of basaltic volcanism have developed over 10 Myr, and episodes appear to migrate southward from 15° to 20°S. Long lava flows increase southward as area/volume of fields increases, but topography, vent distributions, and uplifts play a role. This is attributed to magmatic plume activation within a tensional zone, as lithosphere moves over mantle thermal anomalies. The plume model predicts peak magmatism under the McBride field, coincident with the Undara long lava flow and that long lava flow fields will erupt for another 5-10 Myr. Queensland's movement over a major N-S thermal system imparts a consistent isotopic signature to its northern younger basalts, distinct to basalts from older or more southern thermal systems. Australia's motion toward this northern thermal system will give north Queensland fields continued vigorous volcanism, in contrast to the Victorian field which is leaving its southern thermal system.

Three repellents were compared: Autan Repel containing 9.3% picaridin, RID containing 10% deet, and Bushman Ultra containing 80% deet in a gel. The predominant mosquito species collected were Culex annulirostris Skuse (63.2%), Ochlerotatus normanensis (Taylor) (19.6%), and Anopheles meraukensis Venhuis (8.6%). Autan Repel provided >95% protection against all mosquitoes for 2 h, RID for 7 h, and Bushman for >8 h. Against Cx. annulirostris, Autan Repel provided >95% protection for 5 h, RID for 7 h, and Bushman for >8 h. The study showed that both deet formulations provided significantly better protection against mosquitoes than picaridin (Autan Repel). All 3 repellents provided good protection against Cx. annulirostris, an important vector of arboviruses in Australia.

    Pooled analyses of epidemiological studies have reported an association between prolonged residential exposure to power-frequency magnetic fields of >0.4 μT and an increased risk in childhood leukaemia. In order to compare residential magnetic fields in Australia with those in other countries, a survey was conducted in 296 randomly selected homes in Melbourne. Magnetic fields were assessed by performing spot measurements throughout the house and 24-h measurements in rooms where children spend large amounts of time. Children's exposure in Australia was generally comparable with that in other countries with average fields of 0.05-0.06 μT (95 % CI 0.05-0.06 μT). Prolonged exposure of >0.4 μT was shown in ∼2 % of the homes (95 % CI 0.2-3.6 %) mainly being due to close proximity of the house to transmission lines. Based on the results of this survey, the public health impact of a causal association between residential magnetic fields and childhood leukaemia is expected to be small. © The Author 2014.

    Field efficacy of repellent formulations containing picaridin (1-methyl-propyl 2-(2-hydroxyethyl)-1-piperidinecarboxylate) or deet (N,N,-diethyl-3-methylbenzamide) against mosquitoes in Northern Territory, Australia, was evaluated. The following repellent treatments were evaluated: 19.2% picaridin (Autan Repel Army 20), a solution of 20% deet in ethanol, and 35% deet in a gel (Australian Defense Force [ADF]). The predominant mosquito species were Culex annulirostris Skuse (57.8%), Anopheles merankensis Venhuis (15.4%), and Anopheles bancroftii Giles (13.2%). The protection provided by repellents against Anopheles spp. was relatively poor, with 19.2% picaridin and ADF deet providing >95% protection for only 1 h, whereas 20% deet provided <95% protection at 1 h after repellent application. In contrast, the repellents provided good protection against Cx. annulirostris, with 19.2% picaridin providing >95% protection for 5 h and both deet formulations providing >95% protection for 7 h when collections ceased. This study provides additional field data showing tolerance of Anopheles spp. for repellents. The response of field populations of Cx. annulirostris, an important vector of arboviruses in Australia, to repellents containing deet and picaridin is reported for the first time.

In the laboratory, both compounds provided between 150 and 195 min of protection against Aedes aegypti and between 18 and 80 min of protection against Anopheles farauti. In laboratory tests against Culex annulirostris, 20% SS220 provided 3 h of protection and 20% deet provided >6 h of protection. A field efficacy test was conducted at Redcliffe, Queensland in January 2008 and the predominant mosquito species collected was Cx. annulirostris (84.4% of collection). In the field, 20% SS220 provided significantly better protection against mosquitoes than 20% deet. Seven hours after application, SS220 provided greater than 96.0% protection against all mosquitoes, whereas 20% deet provided 58.9% protection.

    Gyrate atrophy of the choroid and retina is a rare chorioretinal dystrophy inherited in an autosomal recessive pattern. We describe the first documented case of gyrate atrophy from Australia in a 56-year-old woman with a history of previous diagnosis of retinitis pigmentosa and worsening night vision in her right eye over several years. She was myopic and bilaterally pseudophakic, and fundus examination revealed pale optic discs and extensive peripheral chorioretinal atrophy exposing bare sclera bilaterally with only small islands of normal-appearing retina at each posterior pole. Visual field testing showed grossly constricted fields, blood testing showed hyperornithinemia, and further questioning revealed consanguinity between the patient’s parents. We then used the patient’s typical retinal findings of gyrate atrophy to demonstrate the potential use of ultrawide-field fundus photography and angiography in diagnosis and monitoring response in future treatment.

    In areas of limited or zero basement exposure, potential field analysis provides an invaluable tool for determining the architecture continental cratons. We present an example from the Northern Gawler Craton, Australia. Here, the basement rocks are almost completely covered by Neoproterozoic and younger sedimentary rocks (with <<1% basement outcrop), so are amongst the least studied on the Australian continent. However, these rocks should preserve the best record of the Gawler Craton's interactions with neighbouring cratons during the amalgamation of Proterozoic Australia. We focus on the basement architecture in the Marla region of the northernmost Gawler Craton. We use geophysical techniques and apply a top-down approach to penetrate the significant thickness of cover and determine the structure of the unexposed northern Gawler Craton. The architecture, density and magnetic susceptibility of the overlying cover sequences are constrained from the surficial geology, borehole data and seismic reflection profiles. The effect of these cover sequences is then removed from gravity and magnetic data highlighting the basement structure. We then determine the architecture of the basement with depth from the potential field data by combining depth-to-source analyses, with forward and inverse modelling techniques constrained by petrophysical data from drill-holes. Results of this analysis include the observation of a major crustal boundary at the NE-SW trending Middle Bore Fault. To the NW of this boundary, crustal scale sources produce large gravity and magnetic anomalies. Whereas to the SE anomalies are sourced in the upper crust and overlie uniform middle to lower crust. We suggest that the Middle Bore Fault represents a boundary between allochthonous terranes that may have accreted to the Gawler craton during the Kimban Orogeny (~1.7 Ga) and the Archaean Gawler Craton that is overlain by Paleoproterozoic metasediments.

    In the last two decades, ambient noise studies in the range of 1-20 seconds have predominantly focused on the analysis of source regions for Rayleigh and P waves. The theoretical excitation of these phases is well understood for primary microseisms (direct coupling of gravity waves in sloping shallow bathymetry) and secondary microseisms (wave-wave interaction) and correlates well with observations. For Love waves, the excitation mechanism in the secondary microseism band is to date unknown. It has been shown, that LQ waves can exhibit larger amplitudes than Rg waves for certain frequencies. Therefore detailed analysis of the wave field are necessary to find indications on the generation mechanism. We analyse data from two spiral-shaped arrays located in Australia, the Pilbara Array (PSAR) in the North-West and an array in South Queensland (SQspa) in the East. The two arrays are different in aperture and allow for the study of primary and secondary microseisms with SQspa and higher secondary microseisms with PSAR. We use a deconvolution enhanced beamforming approach, which is based on the CLEAN algorithm. It allows the accurate detection of weaker sources and the estimation of power levels on each component or wave type. For PSAR we evaluate 1 year of data in the frequency range of 0.35-1 Hz and find fundamental and higher mode Rg and LQ waves. For the low end of the frequency range, we find the strongest fundamental mode Rg waves to originate from multiple direction, but confined to coastline reflectors, i.e. coastlines that are perpendicular to the main swell direction, while higher mode Rg waves are mainly generated in the Great Australian Bight. For higher frequencies, the source locations of Rg waves move toward the north coast, which is closest to the array and we see an increase in the Lg phase. The majority of fundamental LQ waves are generated at the west coast of Australia and we find some agreement between low frequency Rg and LQ source locations, which

    An investigation into the health of green turtles was undertaken near Gladstone, Queensland, in response to a dramatic increase in stranding numbers in the first half of 2011. A total of 56 live turtles were subject to clinical examination and blood sampling for routine blood profiles, and 12 deceased turtles underwent a thorough necropsy examination. This population of green turtles was found to be in poor body condition and a range of infectious and non-infectious conditions were identified in the unhealthy turtles, including hepato-renal insufficiency (up to 81%, 27/33 based on clinical pathology), cachexia (92%, 11/12), parasitism (75%, 9/12), cardiopulmonary anomalies (42%, 5/12), gastroenteritis (25%, 3/12), masses (25%, 3/12) and mechanical impediments (17%, 2/12 based on necropsy). Overall, there was no evidence to indicate a unifying disease as a primary cause of the mass mortality. Recent adverse weather events, historic regional contamination and nearby industrial activities are discussed as potential causative factors.

  4. Using potential field data for petroleum exploration targeting, Amadeus Basin, Australia

    NASA Astrophysics Data System (ADS)

    Dentith, Mike; Cowan, Duncan

    2011-09-01

    The Amadeus Basin, a large Proterozoic basin located in central Australia, is one of the least explored onshore petroleum-bearing basins with proven reserves in Australia. The size and remoteness of the Amadeus Basin makes ground exploration expensive so this study uses aerogravity and aeromagnetic data to assess petroleum prospectivity. In the western part of the Amadeus Basin the Gillen Petroleum System is considered most significant; this system has the important characteristic that the source in the Bitter Springs Formation is stratigraphically higher than the potential reservoirs within the Dean/Heavitree Quartzite. Thin skinned deformation is expected at the source level and above, with detachments at evaporitic horizons, but deformation of the reservoir is expected to be thick-skinned. This model can form the basis for predicting potential field responses. The most prospective areas are where: (i) gravity suggests basement (and reservoir) is shallow; (ii) magnetics maps fold-thrust complexes (structural trap); and (iii) these features occur adjacent to gravity lows, indicative of significant thicknesses of basin fill (source at depth and below reservoir). Faults at the margins of the depocentre (mapped using magnetic data) provide a possible migration path for the hydrocarbons. Favourable scenarios for younger petroleum systems are antiforms in fold-thrust complexes in units assigned to the Boord Formation and younger units. The juxtaposition of these structures with depocentres suggested by negative gravity anomalies constitutes a favourable exploration scenario. Regardless of specific exploration targets, this study demonstrates that airborne gravity and magnetic data are capable of resolving intra-basin structures in sufficient detail to allow prospective areas to be identified and for follow-up seismic surveys to be reliably planned.

    Airborne geophysics has been used at the catchment scale to map salt stores, conduits and soil variability, but few studies have evaluated its usefulness as a land management tool at the field scale. We respond to questions posed by land managers with: (1) comparison of airborne and ground-based electromagnetic surveys in the Lower Balonne catchment, Queensland, and (2) comparison with historical and anecdotal knowledge of landscape response in the country around Jamestown in mid-South Australia. In the Lower Balonne, direct comparison between ground electromagnetic survey (EM) and airborne electromagnetics (AEM) showed a strong relationship for both the absolute values and spatial patterns of conductivity. The penetration of AEM to greater than 100 m is valuable in defining hydrological barriers. In the Jamestown area, AEM conductivity corresponded well with specific outbreaks of salinity and observed variability in crop response; local inconsistencies at the ground surface could be resolved when sub-surface data were considered. AEM can provide valuable information at the field scale that is relevant to salinity management. Farmers can have confidence in any of these techniques (historical information, EM and AEM) and they may directly compare or integrate the results.

    Field trials comparing repellent formulations containing IR3535 (ethyl butylacetylaminopropionate) and deet (N,N-diethyl-3-methylbenzamide) against mosquitoes in Queensland, Australia, were conducted. Two repellents were compared: Avon Bug Guard, containing 7.5% IR3535; and Australian Defense Force (ADF) deet, containing 35% deet in a gel. Two tests were conducted, one in February-March 2006, and the second in February 2007. In the 1st test, the predominant mosquito species collected were Mansonia uniformis (58.9% of collection) and Culex annulirostris (33.4%), and in the 2nd test, the predominant species was Aedes vigilax (85.7% of collection). In the 1st test, Avon Bug Guard provided >95% protection against all mosquitoes for only 1 h, and ADF deet provided the same level of protection for 5 h. In the 2nd field test, Avon Bug Guard provided only 85% protection against all mosquitoes 1 h after repellent application, while ADF deet provided 5 h of protection. The study showed that ADF deet provided significantly better protection against mosquitoes than Avon Bug Guard (IR3535).

    It is common for at least one monitoring well to be located proximally to a production well. This presents the possibility of applying crosswell technologies to resolve a range of earth properties between the wells. We present both field and synthetic examples of dual well walk-away vertical seismic profiling in vertical wells and show how the direct arrivals from a virtual source may be used to create velocity images between the wells. The synthetic experiments highlight the potential of virtual source crosswell tomography where large numbers of closely spaced receivers can be deployed in multiple wells. The field experiment is completed in two monitoring wells at an aquifer storage and recovery site near Perth, Western Australia. For this site, the crosswell velocity distribution recovered from inversion of travel times between in-hole virtual sources and receivers is highly consistent with what is expected from sonic logging and detailed zero-offset vertical seismic profiling. When compared to conventional walkaway vertical seismic profiling, the only additional effort required to complete dual-well walkaway vertical seismic profiling is the deployment of seismic sensors in the second well. The significant advantage of virtual source crosswell tomography is realised where strong near surface heterogeneity results in large travel time statics.

    The efficacy of Distance Plus Ant Bait, containing the insect growth regulator pyriproxyfen, was tested in the field against two invasive ant species in northern Australia: African big-headed ant (Pheidole megacephala (F.)) and yellow crazy ant (Anoplolepis gracilipes (Fr. Smith)). Results were also gained for a third pest species, Singapore ant (Monomorium destructor (Jerdon)), from one trial focused primarily on P. megacephala. Five studies were conducted throughout northern Australia, each with different protocols, but common to all was the broad-scale dispersal of Distance Plus, coupled with long-term monitoring of ant population levels. Additionally, a laboratory trial was conducted to assess if there was a direct toxic effect by the bait on A. gracilipes workers, and ant community data were collected at some sites in the A. gracilipes trial to assess nontarget impacts and subsequent ecological recovery. All three species were greatly affected by the treatments. The abundance of P. megacephala declined dramatically in all trials, and by the final assessment for each study, very few ants remained, with those remaining being attributable to edge effects from neighboring untreated properties. At both sites that it occurred, M. destructor was initially at least codominant with P. megacephala, but by the final assessment, only three M. destructor individuals were present at one lure at one site, and only a single individual at the other site. Abundance of A. gracilipes fell, on average, to 31% of control levels by 91 d and then slowly recovered, with subsequent treatments only providing slightly greater control. No direct toxic effect on workers was found in the laboratory trial, indicating that population declines of A. gracilipes were typical bait-related declines resulting from reduced worker replacement. Nontarget impacts of the bait could not be distinguished from the negative competitive impacts ofA. gracilipes, but there was a noticeable absence of some key

    Intermittent dosing of free nitrous acid (FNA), with or without the simultaneous dosing of hydrogen peroxide, is a new strategy developed recently for the control of sulfide production in sewers. Six-month field trials have been carried out in a rising main sewer in Australia (150 mm in diameter and 1080 m in length) to evaluate the performance of the strategy that was previously demonstrated in laboratory studies. In each trial, FNA was dosed at a pumping station for a period of 8 or 24 h, some with simultaneous hydrogen peroxide dosing. The sulfide control effectiveness was monitored by measuring, on-line, the dissolved sulfide concentration at a downstream location of the pipeline (828 m from the pumping station) and the gaseous H2S concentration at the discharge manhole. Effective sulfide control was achieved in all nine consecutive trials, with sulfide production reduced by more than 80% in 10 days following each dose. Later trials achieved better control efficiency than the first few trials possibly due to the disrupting effects of FNA on sewer biofilms. This suggests that an initial strong dose (more chemical consumption) followed by maintenance dosing (less chemical consumption) could be a very cost-effective way to achieve consistent control efficiency. It was also found that heavy rainfall slowed the recovery of sulfide production after dosing, likely due to the dilution effects and reduced retention time. Overall, intermittent dose of FNA or FNA in combination with H2O2 was successfully demonstrated to be a cost-effective method for sulfide control in rising main sewers. Copyright © 2013 Elsevier Ltd.

  13. The statesman and the ophthalmologist: Gladstone and Magnus on the evolution of human colour vision, one small episode of the nineteenth-century Darwinian debate.

    PubMed

    1999-01-01

    Among the numerous nineteenth-century sorties into particular aspects of the Darwinian debate are two 1877 publications. The first, Die Geschichtliche Entwickelung des Farbensinnes, was a treatise on the evolutionary development of human colour vision by Hugo Magnus, an obscure German ophthalmologist. The other, The Colour-Sense, was an article by William Ewart Gladstone, the great British statesman. Magnus, working from linguistic science and optical physiology, developed the theory that humankind had passed through successive stages of colour recognition, from none to full perception, brightest colours first. Gladstone supported the theory with data from his studies of Homeric colour words, placing Homer at a very early stage. Their theory was not accepted. It assumed colour vocabulary to be an index of colour recognition, and too little was known about the nature or age of early man. The present study intends to follow this particular episode as an excellent example of the scholarship, argumentation, and limited scientific knowledge of the time, as applied to human evolution.

    Carbon (C) sequestration potential of biochar depends on its stability and stabilisation of native or added organic C in soil. However, the processes of biochar degradation, fate in soil organic matter pools, and downward translocation in the soil profile, and the influence of biochar on emissions or stabilisation of native organic C sources are poorly understood under field conditions. An Eucalyptus saligna green-waste biochar (δ13C -36.6o; total C 66.8%) produced by slow pyrolysis at 450° C was applied at 29.2 t ha-1 to 10-cm depth in circular (0.66-m diameter) micro-plots, encompassing three soils [Tenosol, Dermosol and Ferrosol (Australian Soil Classification); Arenosol, Planosol, Ferralsol (approximate WRB Classification] under contrasting pasture systems across New South Wales and Tasmania (Australia). The aims of this study were to (i) monitor the fate of biochar C in respired CO2 and quantify biochar stability and stabilisation under field conditions, (ii) determine the influence of biochar on native soil C emissions, and (iii) track downward migration of the surface (0-10 cm) applied biochar over a 1-year period. We also periodically monitored the impact of biochar on microbial biomass carbon (MBC) and aboveground biomass production. The soils were separated into light and heavy C fractions and the C recovery of applied biochar C was calculated at 0-8, 8-12, 12-20 and 20-30 cm depths. Biochar C mineralisation rates were generally higher, albeit fluctuated widely, in the first 3 to 4 months. Over the first 7 months, the proportion of added biochar C mineralised in soils ranged between 1.4 and 5.5% and followed the sequence: Tenosol < Dermosol < Ferrosol. The mean residence time (MRT) of biochar ranged from 29 and 70 years. These values of MRT should be treated as highly conservative values, as they mainly reflect the MRT of relatively labile C components in biochar.

  18. Geochemical characteristics of lava-field basalts from eastern Australia and inferred sources: Connections with the subcontinental lithospheric mantle?

    NASA Astrophysics Data System (ADS)

    O'Reilly, Suzanne Y.; Zhang, Ming

    1995-08-01

    A large new database of major, trace elements and Sr-Nd isotopic ratios from 11 lava-field provinces in New South Wales and Queensland, eastern Australia allows detailed interpretation of the origin of these basaltic magmas. Isotopic signatures and trace element patterns identify an OIB-type (oceanic island basalt) source as a dominant component for most of these and some provinces appear to have additional significant components derived from the subcontinental lithospheric mantle (SCLM). The SCLM components have geochemical characteristics that overlap those observed in spinel lherzolite xenoliths (samples of shallow lithospheric mantle) from eastern Australia. These SCLM components show geochemical provinciality that indicates the occurrence of distinct geochemical lithospheric domains reflecting the timing and style of tectonic evolution of different regions. One component reflects modification by subduction-related processes during the late Paleozoic and Mesozoic, one records enrichment by fluids during old metasomatic events and another suggests a metasomatic event involving a distinctive amphibole and apatite-style enrichment. The composition and age distribution of volcanic lava-field provinces older than 10 Ma are consistent with a model involving a regional upwelling (elongated N-S along eastern Australia) of deep hot mantle related to marginal rifting and with OIB-type source geochemical characteristics. Thermal inhomogeneities within this plume swath resulted in small diapirs which may have undergone melt segregation at about 100 km and incorporated varying amounts of SCLM components there or from higher levels of the SCLM during ascent. Subsequent hot-spot generated central volcanoes overprinted this lava-field volcanism, tapped a similar OIB-type source component and truncated the thermal events.

    Field trials to compare repellent formulations containing either picaridin or deet against rainforest mosquitoes in northern Queensland, Australia, were conducted. Three repellents were compared at night: 9.3% picaridin and 19.2% picaridin (Autan Repel and Autan Repel Army 20, respectively, Bayer, Sydney, Australia) and 35% deet in a gel (Australian Defense Force [ADF]). During the day, the following three repellents were compared: 19.2% picaridin, 20% deet in a controlled release formulation (Sawyer Controlled Release Deet), and 33% deet in a polymer formulation (U.S. Army Extended Duration Topical Insect and Arthropod Repellent [EDTIAR]). The predominant mosquito species collected was Verrallina lineata (Taylor), with smaller numbers of Ochlerotatus kochi (Donitz), Anopheles farauti s.s. Laveran, Ochlerotatus notoscriptus (Skuse), and Coquilletidia xanthogaster (Edwards). In nighttime tests, 19.2% picaridin provided >94.7% protection for at least 9 h, and ADF deet provided >95% protection for 7 h. The 9.3% picaridin formulation provided >95% protection for only 2 h, and provided 60% protection at 9 h. In daytime tests, Sawyer 20% deet provided >95% protection for 6 h, and both 19.2% picaridin and U.S. Army EDTIAR provided >95% protection for 8 h. In both nighttime and daytime tests 19.2% picaridin provided similar or better protection than deet formulations.

    The mosquito repellent efficacy of New Mountain Sandalwood Mosquito Sticks (containing 0.5% w/w essential oils) and New Mountain Sandalwood Botanical Repellent (containing soybean and geranium oils) was assessed. Tests were conducted in the field with 4 volunteers in a wooded area near Cairns, North Queensland, Australia. Predominant biting species were Verrallina funerea and Ve. lineata. A pair of burning Mosquito Sticks immediately upwind of the subject (acting as an area repellent) provided a 73.1% mean reduction in mosquito landing and probing over the 3-h test period. The Botanical Repellent and a DEET-based control were both 100% effective in preventing mosquito probing for 3 h. These data are consistent with other studies of area repellents in that such products provide significant protection from mosquito bites, albeit inferior to the protection provided by topically applied repellents.

    Rare ruby crystals appear among prevailing sapphire crystals mined from placers within basaltic areas in the New England gem-field, New South Wales, Australia. New England ruby (NER) has distinctive trace element features compared to those from ruby elsewhere in Australia and indeed most ruby from across the world. The NER suite includes ruby (up to 3370 ppm Cr), pink sapphire (up to 1520 ppm Cr), white sapphire (up to 910 ppm) and violet, mauve, purple, or bluish sapphire (up to 1410 ppm Cr). Some crystals show outward growth banding in this respective colour sequence. All four colour zones are notably high in Ga (up to 310 ppm) and Si (up to 1820 ppm). High Ga and Ga/Mg values are unusual in ruby and its trace element plots (laser ablation-inductively coupled plasma-mass spectrometry) and suggests that magmatic-metasomatic inputs were involved in the NER suite genesis. In situ oxygen isotope analyses (secondary ion mass spectrometry) across the NER suite colour range showed little variation (n = 22; δ18O = 4.4 ± 0.4, 2σ error), and are values typical for corundum associated with ultramafic/mafic rocks. The isolated NER xenocryst suite, corroded by basalt transport and with few internal inclusions, presents a challenge in deciphering its exact origin. Detailed consideration of its high Ga chemistry in relation to the known geology of the surrounding region was used to narrow down potential sources. These include Late Palaeozoic-Triassic fractionated I-type granitoid magmas or Mesozoic-Cenozoic felsic fractionates from basaltic magmas that interacted with early Palaeozoic Cr-bearing ophiolite bodies in the New England Orogen. Other potential sources may lie deeper within lower crust-mantle metamorphic assemblages, but need to match the anomalous high-Ga geochemistry of the New England ruby suite.

  7. Assessment of bias in a survey of residential magnetic fields in Melbourne, Australia.

    2015-01-01

    An important consideration in surveys of residential magnetic fields is whether the sample of homes measured is representative of the population. This study assessed the potential bias in a survey of magnetic fields conducted in 296 homes randomly selected from the telephone directory in Melbourne. The choice of the telephone directory as the sampling frame introduced some bias when compared with census information. There was also evident self-selection bias with residents twice as likely to participate if they lived in the vicinity of visible electrical infrastructure such as transmission lines. However, when corrected for bias the corrected magnetic fields were only slightly lower than the measurements with a percentage difference in the range of 2.8-6.0 %. These results provide confidence that the measurements in the survey were good estimates of the distribution of residential magnetic fields in Melbourne. © The Author 2014.

    The numerical wave model SWAN (Simulating WAves Nearshore) and historical wave buoy observations were used to investigate the response of surface wave fields to tropical cyclone (TC) wind forcing on the Australian North West Shelf (NWS). Analysis of historical wave data during TC events at a key location on the NWS showed that an average of 1.7 large TCs impacted the region each year, albeit with high variability in TC track, intensity and size, and also in the surface wave field response. An accurately modeled TC wind field resulted in a good prediction of the observed extreme wave conditions by SWAN. Results showed that the presence of strong background winds during a TC and a long TC lifetime (with large variations in translation speed) can provide additional energy input. This potentially enhances the generated swell waves and increases the spatial extent of the TC generated surface wave fields. For the TC translation speeds in this study, a positive relationship between TC translation speed and the resulting maximum significant wave height and wave field asymmetry was observed. Bottom friction across the wide NWS limited the amount of wave energy reaching the coastal region; consistently reducing wave energy in depths below 50 m, and in the case of the most extreme conditions, in depths up to 100 m that comprise much of the shelf. Nevertheless, whitecapping was still the dominant dissipation mechanism on the broader shelf region. Shelf-scale refraction had little effect on the amount of wave energy reaching the nearshore zone; however, refraction locally enhanced or reduced wave energy depending on the orientation of the isobaths with respect to the dominant wave direction during the TC.

    In San Juan County, Colo., the effects of historical mining continue to contribute metals to ground water and surface water. Previous research by the U.S. Geological Survey identified ground-water discharge as a significant pathway for the loading of metals to surface water in the upper Animas River watershed from both acid-mine drainage and acid-rock drainage. In support of this ground-water research effort, Prospect Gulch was selected for further study and the geochemistry of surface and ground water in the area was analyzed as part of four sampling plans: (1) ten streamflow and geochemistry measurements at five stream locations (four locations along Cement Creek plus the mouth of Prospect Gulch from July 2004 through August 2005), (2) detailed stream tracer dilution studies in Prospect Gulch and in Cement Creek from Gladstone to Georgia Gulch in early October 2004, (3) geochemistry of ground water through sampling of monitoring wells, piezometers, mine shafts, and springs, and (4) samples for noble gases and tritium/helium for recharge temperatures (recharge elevation) and ground-water age dating. This report summarizes all of the surface and ground-water data that was collected and includes: (1) all sample collection locations, (2) streamflow and geochemistry, (3) ground-water geochemistry, and (4) noble gas and tritium/helium data.

    The oil and gas-bearing Tirrawarra Sandstone lies in the basal section of the Cooper basin sequence, which is largely Permian in age. The sandstone is characteristically thick, but both interfingers with and conformable overlies glacio-lacustrine diamictites and varvites of the late Carboniferous-Early Permian Merrimeleia Formation. The Tirrawarra Sandstone has previously been interpreted as being deposited in a glacio-fluvial braided river environment. The sandstone produces high gas:oil-ratio oil at the Moorari field, from depths of 9,400 ft below sea level. Appraisal and development of the field has been hampered by the patchy distribution of reservoir quality sandstone. This study investigated the cause of reservoir quality variations. For seven cored wells, core facies analysis, core plug porosity/permeability, petrology, and wireline logs were all matched and compared. The results are as follows. (1) Facies states (grain size and bed form) largely control permeability distribution in the Tirrawarra Sandstone at the Moorari field, such that horizontally bedded medium-coarse sandstones are consistently more permeable than cross-bedded equivalents. (2) Diagenesis levels are high and include extensive silica cement and patchy kaolinite and siderite cements. However, diagenesis rarely operates independently of original depositional fabric. (3) An association between depositional environment and permeability is recognizable, with medial bars in particular providing better reservoir quality.

    Introduced Wolbachia bacteria can influence the susceptibility of Aedes aegypti mosquitoes to arboviral infections as well as having detrimental effects on host fitness. Previous field trials demonstrated that the wMel strain of Wolbachia effectively and durably invades Ae. aegypti populations. Here we report on trials of a second strain, wMelPop-PGYP Wolbachia, in field sites in northern Australia (Machans Beach and Babinda) and central Vietnam (Tri Nguyen, Hon Mieu Island), each with contrasting natural Ae. aegypti densities. Mosquitoes were released at the adult or pupal stages for different lengths of time at the sites depending on changes in Wolbachia frequency as assessed through PCR assays of material collected through Biogents-Sentinel (BG-S) traps and ovitraps. Adult numbers were also monitored through BG-S traps. Changes in Wolbachia frequency were compared across hamlets or house blocks. Releases of adult wMelPop-Ae. aegypti resulted in the transient invasion of wMelPop in all three field sites. Invasion at the Australian sites was heterogeneous, reflecting a slower rate of invasion in locations where background mosquito numbers were high. In contrast, invasion across Tri Nguyen was relatively uniform. After cessation of releases, the frequency of wMelPop declined in all sites, most rapidly in Babinda and Tri Nguyen. Within Machans Beach the rate of decrease varied among areas, and wMelPop was detected for several months in an area with a relatively low mosquito density. These findings highlight challenges associated with releasing Wolbachia-Ae. aegypti combinations with low fitness, albeit strong virus interference properties, as a means of sustainable control of dengue virus transmission.

    This paper describes seagrass species and percentage cover point-based field data sets derived from georeferenced photo transects. Annually or biannually over a ten year period (2004-2014) data sets were collected using 30-50 transects, 500-800 m in length distributed across a 142 km2 shallow, clear water seagrass habitat, the Eastern Banks, Moreton Bay, Australia. Each of the eight data sets include seagrass property information derived from approximately 3000 georeferenced, downward looking photographs captured at 2-4 m intervals along the transects. Photographs were manually interpreted to estimate seagrass species composition and percentage cover (Coral Point Count excel; CPCe). Understanding seagrass biology, ecology and dynamics for scientific and management purposes requires point-based data on species composition and cover. This data set, and the methods used to derive it are a globally unique example for seagrass ecological applications. It provides the basis for multiple further studies at this site, regional to global comparative studies, and, for the design of similar monitoring programs elsewhere.

    Insecticide-treated lethal ovitraps are used for control of the dengue vector Aedes aegypti in north Queensland, Australia. In an effort to optimize their use, the influence of deployment height, premise shading, and protection from wind on trap efficacy was assessed in field experiments. Sticky ovitraps were used as a proxy for lethal ovitraps because they provide a direct measure of adult visitation rates. Sticky ovitraps deployed at ground level for 1 wk captured significantly more female Ae. aegypti (mean +/- SE, 1.7 +/- 0.4) than those set at 1.75-m elevation (1.0 +/- 0.3). Setting traps on the leeward side of houses significantly improved collections during a dry season experiment but not in the wet season. Traps set at lightly or heavily shaded premises performed equally well. To determine the optimum number of ovitraps to set per premise, five treatments making up different numbers of traps (1, 2, 4, 6, or 8) were trialled in a Latin square experimental design. Female Ae. aegypti collections increased as more traps were deployed, although mean collections by using 4 (2.6 +/- 0.6), 6 (2.4 +/- 0.5), or 8 traps (4.8 +/- 1.3) could not be separated statistically, suggesting that 4 traps was the optimum number for routine deployment.

    A study to evaluate the protection provided by permethrin-treated military fabric following cold-water washing against host-seeking mosquitoes is reported. The landing/probing of native mosquitoes on Australian Defence Force Disruptive Pattern Combat Uniform shirts treated by dipping in 0.6% permethrin emulsion (Perigen Defence®, containing 500 g/l permethrin), and commercial factory treatments in the USA (Factory A) and Europe (Factory B) were recorded after 0, 1, 3, 5, and 10 washes. The study showed that significantly shorter landing/probing times compared with untreated controls were recorded for shirts treated with Factory A treatment after 0 and 1 wash, and for the Factory B treatment after 0 washes, and there were no differences between permethrin treatment and control landing. The study concludes that better methods to assess protection from landing/probing mosquitoes in the field are needed.

  16. Size-resolved dust flux measurements in a fallow wheat field from the Japan-Australia Dust Experiment (JADE)

    The time- and size-resolved dust flux was observed by using optical particle counters and profile measurements of wind speed and air temperature on a dry, non-crusted fallow wheat field in Australia during the Japan-Australia Dust Experiment (JADE). Mineral dust emitted from the ground surface into the atmosphere by strong winds is transported around the globe and can have effects on cloud properties and thus on climate. Therefore not only on the amount of dust but also on the size of the dust particles is important. To evaluate the power n of the law linking dust flux to friction velocity according to the particle size, the time- and size-resolved number and mass concentrations were measured and dust flux along with the friction velocity was evaluated by a gradient method. This observation shows the simple relationship between diffusion dust flux and friction velocity using power law to address questions: what is the best value to use for the power n? Does the n has the particle size dependency? The dust concentration and dust flux fluctuated greatly with time, and the fluctuations corresponded well with fluctuations in u*. The trend of the relationship between friction velocity and dust flux was similar across all measured particle sizes. Size distributions of suspended dust particles at two different heights (1 and 3.5 m) had a similar shape and modal behavior. This is different from saltation sand particles. This result indicates that dust particles were transported by vertical turbulent eddy motions. As for dust mass flux, particles ranging in size from 2.0 to 8.4 μm composed 90% and particles from 0.6 to 2.0 μm composed 10%. While, finer dusts are dominant for number concentration. Number concentration and mass flux behave differently. The dust flux integrated from 0.6 to 8.4 μm in six bins fluctuated greatly, depending on friction velocity. When the power law equation was fitted to the data for each particle size range, the power n should be determined

    Cyclopentanone is a saturated monoketone typically used as an intermediate in the manufacture of pharmaceuticals, biologicals, insecticides, and rubber chemicals. Recently, it has been demonstrated that cyclopentanone activates the cpA CO2 receptor neuron on the maxillary palp of mosquitoes, suggesting that it may be a viable alternative to CO2 as an attractant for mosquitoes. Furthermore, semifield experiments showed that traps baited with cyclopentanone attract Culex quinquefasciatus Say at a similar rate to those baited with CO2. We evaluated the field efficacy of cyclopentanone as an alternative to CO2 in Centers for Disease Control (CDC) light traps and counterflow geometry (CFG) traps commonly used to collect mosquitoes in surveillance programs. Three pairwise trials and four Latin square trials were conducted across three peri-urban sites, comprising two saltwater sites and one freshwater site, in southeast Queensland, Australia. In all trials, CO2-baited traps outperformed traps baited with cyclopentanone. Carbon dioxide-baited CDC traps collected significantly more total mosquitoes, Aedes vigilax (Skuse), Culex sitiens Weidemann, and Culex annulirostris Skuse, than those baited with ≥99% cyclopentanone in pairwise trials. Similarly, in almost all Latin square trials, CO2-baited CDC and CFG traps collected significantly greater numbers of total mosquitoes, Ae. vigilax, Cx. annulirostris, Culex orbostiensis Dobrotworsky, and Cx. sitiens when compared with CFG traps baited with 20% cyclopentanone. Our trials indicate that cyclopentanone is not effective as a mosquito attractant in the field and cannot be used as a simple substitute for CO2 in commonly used mosquito surveillance traps.

    Changes to benthic infauna caused by exploratory gas drilling operations in the Minerva field were examined experimentally using a BACI (before, after, control, impact) design. Analysis of 72 x 0.1 m2 Smith-McIntyre grab samples obtained from one pre-drilling and three post-drilling periods yielded a diverse fauna consisting of 196 invertebrate species and 5035 individuals. Changes to benthic community structure were assessed using ANOVA and nonmetric multidimensional scaling (MDS). The abundances of two common species (Apseudes sp. 1 and Prionospio coorilla) decreased significantly at the well-head site immediately after drilling. The size of these reductions in abundance ranged between 71% and 88%, and persisted for less than 4 months after drilling. A third common species (Katlysia sp. 1) increased in abundance 200 m east of the well-head following drilling. Most species occurred at densities too low to be analysed individually and so were pooled at higher taxonomic levels. Changes in the abundance of species aggregated by phylum varied, but significant declines in the most abundant phyla (Crustaceans and Polychaetes) of 45-73% were observed at all sites within a 100 m radius of the well-head following drilling. In most cases these changes became undetectable four months after drilling following species recruitments. MDS ordinations confirm that drilling related changes to benthic community structure are most pronounced at stations located closest to the well-head. Additionally, the ordinations indicate that modified communities persist at the well-head for more than 11 months following exploratory drilling.

  19. Organic tissues, graphite, and hydrocarbons in host rocks of the Rum Jungle Uranium Field, northern Australia

    The Rum Jungle Uranium field consists of at least six early Proterozoic deposits that have been mined either for uranium and/or the associated base and precious metals. Organic matter in the host rocks of the Whites Formation and Coomalie Dolomite is now predominantly graphite, consistent with the metamorphic history of these rocks. For nine samples, the mean total organic carbon content is high (3.9 wt%) and ranged from 0.33 to 10.44 wt%. Palynological extracts from the host rocks include black, filamentous, stellate (Eoastrion-like), and spherical morphotypes, which are typical of early Proterozoic microbiota. The colour, abundance, and shapes of these morphotypes reflect the thermal history, organic richness, and probable lacustrine biofacies of the host rocks. Routine analysis of rock thin sections and of palynological residues shows that mineral grains in some of the host rocks are coated with graphitized organic matter. The grain coating is presumed to result from ultimate thermal degradation of a petroleum phase that existed prior to metamorphism. Hydrocarbons are, however, still present in fluid inclusions within carbonates of the Coomalie Dolomite and lower Whites Formation. The fluid inclusions fluoresce dull orange in blue-light excitation and their hydrocarbon content is confirmed by gas chromatography of whole-rock extracts. Preliminary analysis of the oil suggests that it is migrated, and because it has escaped graphitization through metamorphism it is probably not of early Proterozoic age. The presence of live oil is consistent with fluid inclusion data that suggest subsequent, low-temperature brine migration through the rocks. The present observations support earlier suggestions that organic matter in the host formations trapped uranium to form protore. Subsequent fluid migrations probably brought additional uranium and other metals to these formations, and the organic matter provided a reducing environment for entrapment. ?? 1990.

    Using the 1.4 GHz Australia Telescope Large Area Survey, supplemented by the 1.4 GHz Very Large Array images, we undertook a search for bent-tailed (BT) radio galaxies in the Chandra Deep Field South. Here we present a catalog of 56 detections, which include 45 BT sources, 4 diffuse low-surface-brightness objects (1 relic, 2 halos, and 1 unclassified object), and a further 7 complex, multi-component sources. We report BT sources with rest-frame powers in the range 10{sup 22} ≤ P {sub 1.4} {sub GHz} ≤ 10{sup 26} W Hz{sup –1}, with redshifts up to 2 and linear extents from tens of kiloparsecs up to about 1 Mpc. This is the first systematic study of such sources down to such low powers and high redshifts and demonstrates the complementary nature of searches in deep, limited area surveys as compared to shallower, large surveys. Of the sources presented here, one is the most distant BT source yet detected at a redshift of 2.1688. Two of the sources are found to be associated with known clusters: a wide-angle tail source in A3141 and a putative radio relic which appears at the infall region between the galaxy group MZ 00108 and the galaxy cluster AMPCC 40. Further observations are required to confirm the relic detection, which, if successful, would demonstrate this to be the least powerful relic yet seen with P {sub 1.4} {sub GHz} = 9 × 10{sup 22} W Hz{sup –1}. Using these data, we predict future 1.4 GHz all-sky surveys with a resolution of ∼10 arcsec and a sensitivity of 10 μJy will detect of the order of 560,000 extended low-surface-brightness radio sources of which 440,000 will have a BT morphology.

    This second paper reports the results of plant growth, plant mortality, plant leaf tissue metal and salt concentrations and leachate quality monitoring from lysimeters in four large field trial treatments established on sulfidic waste rock/soil that was used for haul road construction at a closed gold mine in Australia. The TerraB™, lime and clay treatments allowed good tree growth of four Eucalypt species, compared to the control. There was no statistical difference in tree growth between the TerraB™, lime or clay treatments over the 2 years of monitoring in this paper. However, the growth of one tree species was poor in the TerraB™ treatment. Leaf tissue metal and major ion data are also presented. Leachate pH in the control became increasingly acidic (pH 4.57-3.95). The addition of Ca(OH)2 and biosolids led to an initial increase in leachate pH, compared to the control; however, this has decreased over the duration of the study (pH 5.37-4.89) and may affect the sustainable growth of plants in the future. In the TerraB™ and biosolids treatment leachate pH increased to 6.92 after the first rainfall event and continued to increase over the duration of the study to pH 7.4 after 24 months. After 24 months average heavy metal leachate concentrations (mg/L) in the lysimeters for Al, Cd, Cu, Mn and Zn were, control: 32.55, 5.67, 12.71, 39.29, 121.80, TerraB™: 0.07, 0.02, 0.07, 0.57, 0.23, and lime: 2.19, 1.19, 2.33, 3.6, 28.4. No leachate was available for collection from the clay treatment indicating that this technique was functioning in terms of minimizing the infiltration of water into the mine soil.

    Stratigraphic transition of black chert to iron-rich sedimentary rocks above volcanic sequences with hydrothermal systems is common and characteristic feature of Archean greenstone belts. The 3.2 Ga Dixon Island Formation, exposed along the northern coast of Dixon Island located in the coastal Pilbara terrane, Western Australia, is one of such units and the focus of our study. We introduce field occurrence and lithology of the Dixon Island Formation that preserves features of paleohydrohermal environment in the Mesoarchean ocean. The Dixon Island Formation is composed of the following three members (in ascending order): Komatiite-Rhyolite Tuff, Black Chert, and Varicolored Chert members (Kiyokawa and Taira, 1998). Here we focus on the Komatiite-Rholite Tuff member. It preserves two cycles of highly altered komatiite lavas and well-stratified rhyolite tuff. Komatiite lavas include dendritic crystals of chrome spinel and ghosts of spinifex, euhedral and sheet-like olivines and pyroxenes. These rocks are now composed of granular microcrystalline quartz with chromian muscovite, chrome spinel and chrorite that formed by intense silicification. Its upper part contains hydrothermal veining and alteration (i.e., many vein swarms composed of veins of quartz and organic carbon-rich black chert). Most black chert veins intrude vertically into overlying layers, and contain barite, pyrite, monazite and clay minerals which were least affected by silicificatio. Based on the cross-cutting relationship seen in the outcrops, we recognized two generations of black chert veins (type 1 and type 2 veins; Kiyokawa et al., 2006). Type 1 veins are mainly composed of carbonaceous peloids in a microcrystalline quartz matrix. Euhedral and xenocrystic tourmaline are found only in Type1 veins. Type 2 veins are organic carbon-poor and contain fragments of black chert and siliceous volcanic breccia (Kiyokawa et al., 2006).

    Komatiites in the western part of the Norseman-Wiluna greenstone belt in the Yilgarn Block of Western Australia display a wide variety of volcanic facies, ranging from very thin differentiated Munro Township-type flow units through to very thick olivine-rich cumulate flow units containing high proportions of adcumulate dunite. Cumulate flow units have been mapped in detail in the Agnew-Wiluna segment of the Norseman-Wiluna Greenstone Belt. In the Yakabindie and Mt. Keith areas, thick lenticular bodies of olivine adcumulate are flanked and overlain by thinner sheet-like sequences of finer grained olivine orthocumulates. They show fine-scale internal layering, broad-scale cryptic layering and upper fractionated sequences containing harrisites, pyroxene bearing cumulates and in some cases gabbroic derivatives. Low grade disseminated sulphide mineralisation occurs within the dunite lenses. In the stratigraphically equivalent Kathleen East area adcumulate dunite grades laterally into olivine orthocumulates and spinifex textured flows. A similar relationship is also seen further south, where the Perseverance ultramafic complex consists of a thick central dunite lens flanked on one side by thin fine grained orthocumulate sequences and on the other by intercalated orthocumulates and spinifex textured flows. These field relationships indicate an extrusive origin for the adcumulate dunite bodies. The Walter Williams Formation, in the west-central part of the Norseman-Wiluna Belt, is a very large cumulate flow unit 150 km long and 30 km wide in presently exposed extent. It consists of a central sheet-like body of adcumulate dunite, underlain and overlain by olivine orthocumulates. The adcumulate sheet is everywhere capped by a distinctive thin layer of olivine harrisite. At its northernmost extent, the flow unit consists of cyclically layered olivine and pyroxene bearing cumulates capped by gabbros, dolerites and pyroxene spinifex-textured material, interpreted as a

    Heron Island is located in Queensland, Australia, approximately 45 miles (72 kilometers) off the Australian mainland, to the northeast of Gladstone. Part of Australia's Great Barrier Reef, the island is an evergreen coral cay surrounded by Wistari coral reef. Although just 42 acres in size, the island is home to a large resort and the University of Queensland's Heron Island Research Station. The island is famous for diving and snorkeling and is a World Heritage-Listed Marine National Park. It is one of two locations on the Great Barrier Reef that are serving as bases for in-water validation activities for NASA's Coral Reef Airborne Laboratory (CORAL) mission, which is studying the condition and function of the Great Barrier Reef and selected reef systems worldwide using NASA's airborne Portable Remote Imaging Spectrometer (PRISM) instrument from an altitude of 28,000 feet (8,500 meters). The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft acquired this image of Heron Island and its surroundings on December 22, 2001. The island appears at the left of the reef (Heron Reef) in the center of the image. Vegetation is red on the image. The image covers an area of 10.3 by 18.6 miles (16.5 by 30.0 kilometers), and is located at 23.5 degrees south, 151.9 degrees east. http://photojournal.jpl.nasa.gov/catalog/PIA20900

    This qualitative study aimed to describe field worker perceptions, evaluations of worth, and time costs of routine dengue vector surveillance methods in Cairns (Australia), Kuala Lumpur and Petaling District (Malaysia). In Cairns, the BG-Sentinel trap is a favored method for field workers because of its user-friendliness, but is not as cost-efficient as the sticky ovitrap. In Kuala Lumpur, the Mosquito Larvae Trapping Device is perceived as a solution for the inaccessibility of premises to larval surveys. Nonetheless, the larval survey method is retained in Malaysia for prompt detection of dengue vectors. For dengue vector surveillance to be successful, there needs to be not only technical, quantitative evaluations of method performance but also an appreciation of how amenable field workers are to using particular methods. Here, we report novel field worker perceptions of dengue vector surveillance methods in addition to time analysis for each method. © 2014 APJPH.

    The purposes of this study were: i) to demonstrate the assessment of personal exposure from various RF-EMF sources across different microenvironments in Australia and Belgium, with two on-body calibrated exposimeters, in contrast to earlier studies which employed single, non-on-body calibrated exposimeters; ii) to systematically evaluate the performance of the exposimeters using (on-body) calibration and cross-talk measurements; and iii) to compare the exposure levels measured for one site in each of several selected microenvironments in the two countries. A human subject took part in an on-body calibration of the exposimeter in an anechoic chamber. The same subject collected data on personal exposures across 38 microenvironments (19 in each country) situated in urban, suburban and rural regions. Median personal RF-EMF exposures were estimated: i) of all microenvironments, and ii) across each microenvironment, in two countries. The exposures were then compared across similar microenvironments in two countries (17 in each country). The three highest median total exposure levels were: city center (4.33V/m), residential outdoor (urban) (0.75V/m), and a park (0.75V/m) [Australia]; and a tram station (1.95V/m), city center (0.95V/m), and a park (0.90V/m) [Belgium]. The exposures across nine microenvironments in Melbourne, Australia were lower than the exposures across corresponding microenvironments in Ghent, Belgium (p<0.05). The personal exposures across urban microenvironments were higher than those for rural or suburban microenvironments. Similarly, the exposure levels across outdoor microenvironments were higher than those for indoor microenvironments.

    We present an inversion algorithm for magnetic anomaly data in spherical coordinates to image the three dimensional (3-D) susceptibility distributions in the lithosphere. The method assumes that remanent magnetization is absent and that the magnetic anomalies are solely the result of lateral variations in magnetic susceptibility. To take into account the curvature of the Earth, the 3-D model is comprised of a set of spherical prisms (referred to as tesseroids), each of which has a constant isotropic susceptibility. The inversion method is formulated with a specifically designed model objective function and radial weighting function in spherical coordinates. A Tikhonov regularization technique is used to obtain an optimal solution with data misfit consistent with the estimated error level. Results for regional synthetic models with different magnetized inclinations and declinations are presented to demonstrate the capability of the method to recover large scale lithospheric magnetic structures. We have applied the algoithm to study the lithospheric susceptibility structures in the Australia region using magnetic anomaly data from the GRIMM_L120v0.0 model, which is based on ten years of CHAMP satellite data. As a self-constrained inversion, the maximum depths variation of magnetization layer is estimated first and then incorporated to the three dimensional (3-D) inversion. Results showed that the susceptibility anomalies concentrate in the depth range from 25 km to 45 km, i.e., focused in the lower crust. In addition, the results showed that the susceptibilities in continental lithosphere are higher than those in oceanic lithosphere. The inverted 3-D susceptibility distribution in the region of Australia reveals significant features related to tectonics, surface heat-flux, crustal thickness and Curie isotherm depths. In general, the higher susceptibility anomalies correlate with Precambrian rocks, and the lower susceptibility anomalies correlate with younger orogenic

    2009-01-01

    Background The International Health Regulations (2005) and the emergence and global spread of infectious diseases have triggered a re-assessment of how rich countries should support capacity development for communicable disease control in low and medium income countries (LMIC). In LMIC, three types of public health training have been tried: the university-based model; streamed training for specialised workers; and field-based programs. The first has low rates of production and teaching may not always be based on the needs and priorities of the host country. The second model is efficient, but does not accord the workers sufficient status to enable them to impact on policy. The third has the most potential as a capacity development measure for LMIC, but in practice faces challenges which may limit its ability to promote capacity development. Discussion We describe Australia's first Master of Applied Epidemiology (MAE) model (established in 1991), which uses field-based training to strengthen the control of communicable diseases. A central attribute of this model is the way it partners and complements health department initiatives to enhance workforce skills, health system performance and the evidence-base for policies, programs and practice. Summary The MAE experience throws light on ways Australia could collaborate in regional capacity development initiatives. Key needs are a shared vision for a regional approach to integrate training with initiatives that strengthen service and research, and the pooling of human, financial and technical resources. We focus on communicable diseases, but our findings and recommendations are generalisable to other areas of public health. PMID:19358710

    Mini-mark-release-recapture experiments were conducted in suburban Cairns, Australia to establish the sampling rate of the Biogents-Sentinel (BGS) trap for adult Aedes aegypti (L.). Small cohorts of marked mosquitoes (30 females and 15 males) were released at typical Cairns residences, and the number of marked mosquitoes recaptured in the BGS trap after 24 h was recorded. The sampling rate was compared between two seasons and two common housing styles (high-set 'Queenslander-style' timber and low-set brick houses), between old gravid and young nulliparous females, and between mosquitoes released in different areas of a house. Overall, the BGS traps recaptured a mean (+/- SEM) of 24.6% (+/- 1.9) of the released marked female mosquitoes in 24 h. The mean recapture rate for females was significantly higher in the dry season (30.4% +/- 2.8) compared with the wet (18.8% +/- 2.2). The overall recapture rates did not differ significantly between the two house types, but variability between the individual premises was high. An overall mean of 18.2% (+/- 1.7) of males was collected. Recapture rates of young nullipars and older gravid females were similar. These recapture rates can be used to estimate the population density of Ae. aegypti females in north Queensland, although it will provide an underestimate as trap sample was largely representative of mosquitoes present in the same area as the trap, and not from other areas of the house.

    The 3.4-Ga Strelley Pool Formation (SPF) at the informally named 'Waterfall Locality' in the Goldsworthy greenstone belt of the Pilbara Craton, Western Australia, provides deeper insights into ancient, shallow subaqueous to possibly subaerial ecosystems. Outcrops at this locality contain a thin (<3 m) unit of carbonaceous and non-carbonaceous cherts and silicified sandstones that were deposited in a shallow-water coastal environment, with hydrothermal activities, consistent with the previous studies. Carbonaceous, sulfide-rich massive black cherts with coniform structures up to 3 cm high are characterized by diverse rare earth elements (REE) signatures including enrichment of light [light rare earth elements (LREE)] or middle rare earth elements and by enrichment of heavy metals represented by Zn. The massive black cherts were likely deposited by mixing of hydrothermal and non-hydrothermal fluids. Coniform structures in the cherts are characterized by diffuse laminae composed of sulfide particles, suggesting that unlike stromatolites, they were formed dominantly through physico-chemical processes related to hydrothermal activity. The cherts yield microfossils identical to previously described carbonaceous films, small and large spheres, and lenticular microfossils. In addition, new morphological types such as clusters composed of large carbonaceous spheroids (20-40 μm across each) with fluffy or foam-like envelope are identified. Finely laminated carbonaceous cherts are devoid of heavy metals and characterized by the enrichment of LREE. This chert locally contains conical to domal structures characterized by truncation of laminae and trapping of detrital grains and is interpreted as siliceous stromatolite formed by very early or contemporaneous silicification of biomats with the contribution of silica-rich hydrothermal fluids. Biological affinities of described microfossils and microbes constructing siliceous stromatolites are under investigation. However, this

    Sand-sized spherules up to 1.7 mm across with spherulitic, vesicular, and other crystalline textures that consist mainly of K-feldspar help define a unique horizon in the well-preserved 2.6-Ga Wittenoom Formation in the Hamersley Basin of Western Australia. This layer is informally known as the spherule marker bed. In the northeastern part of the Hamersley Basin, similar spherules again occur at only one horizon, but here they are a minor constituent of a dolomitic debris-flow deposit known as the dolomixtite layer. The dolomixtite layer occurs in the Carawine Dolomite, which is stratigraphically equivalent to the Wittenoom Formation. Moreover, paleocurrent data from closely associated carbonate and volcaniclastic turbidites indicate the spherule marker bed was deposited in deeper-water paleoenvironments than the dolomixtite layer. Therefore, the dolomixtite layer is believed to be a proximal equivalent of the spherule marker bed. The layers that host the spherules are interpreted to be the deposits of a major sediment gravity flow that exhumed and redeposited most of the spherules after shallow burial, although the flow is not believed to have been a direct result of the proposed impact. The most likely site for the proposed impact would have been in the early Precambrian ocean close to the northeastern edge of the Pilbara Craton. Another thin horizon in the overlying Brockman Iron Formation contains spherules that again consist largely of K-feldspar and have internal textures strikingly similar to those of the Wittenoom Formation and Carawine Dolomite. The close resemblance of these spherules to those of the Wittenoom Formation and Carawine Dolomite suggests they also originated as impact melt droplets, even though they are admixed with volcaniclastic detritus. The stratigraphic separation between the two suggests that a second major impact occurred near the Hamersley Basin after a time interval of about 75 m.y. elapsed. This suggests the record of impacts in

    This paper estimates the two-daily extent of savanna burning and consumption of fine (grass and litter) fuels from an extensive 230,000 km2 region of northern Australia during August-September 1999 encompassing the Australian continental component of the Biomass Burning and Lightning Experiment B (BIBLE B) campaign [, 2002]. The extent of burning for the study region was derived from fire scar mapping of imagery from the advanced very high resolution radiometer (AVHRR) on board the National Oceanic and Atmospheric Administration (NOAA) satellite. The mapping was calibrated and verified with reference to one Landsat scene and associated aerial transect validation data. Fine fuel loads were estimated using published fuel accumulation relationships for major regional fuel types. It is estimated that more than 43,000 km2 was burnt during the 25 day study period, with about 19 Mt of fine (grass and litter) fuels. This paper examines assumptions and errors associated with these estimates. It is estimated from uncalibrated fire mapping derived from AVHRR imagery that 417,500 km2 of the northern Australian savanna was burnt in 1999, of which 136,405 km2, or 30%, occurred in the Northern Territory study region. Using generalized fuel accumulation equations, such biomass burning consumed an estimated 212.3 Mt of fine fuels, but no data are available for consumption of coarse fuels. This figure exceeds a recent estimate, based on fine fuels only, for the combined Australian savanna and temperate grassland biomass burning over the period 1990-1999 but is lower than past estimates derived from classification approaches. We conclude that (1) fire maps derived from coarse-resolution optical imagery can be applied relatively reliably to estimate the extent of savanna fires, generally with 70-80% confidence using the approach adopted here, over the major burning period in northern Australia and (2) substantial further field assessment and associated modeling of fuel accumulation

    Runoff from the urban environment is a major contributor of non-point source contamination for many estuaries, yet the ultimate fate of this stormwater within the estuary is frequently unknown in detail. The relationship between catchment rainfall and estuarine response within the Sydney Estuary (Australia) was investigated in the present study. A verified hydrodynamic model (Environmental Fluid Dynamics Computer Code) was utilised in concert with measured salinity data and rainfall measurements to determine the relationship between rainfall and discharge to the estuary, with particular attention being paid to a significant high-precipitation event. A simplified rational method for calculating runoff based upon daily rainfall, subcatchment area and runoff coefficients was found to replicate discharge into the estuary associated with the monitored event. Determining fresh-water supply based upon estuary conditions is a novel technique which may assist those researching systems where field-measured runoff data are not available and where minor field-measured information on catchment characteristics are obtainable. The study concluded that since the monitored fresh-water plume broke down within the estuary, contaminants associated with stormwater runoff due to high-precipitation events (daily rainfall > 50 mm) were retained within the system for a longer period than was previously recognised.

    South-central Australia is home to several deserts, including the Simpson Desert, whose reddish-orange sands are seen in the upper left quadrant of this Moderate Resolution Imaging Spectroradiometer (MODIS) image from July 1, 2002. Several impermanent, salty, lakes stand whitely out against the arid terrain. The largest is North Lake Eyre, southwest of center. At bottom center, Spencer Gulf separates the triangular Eyre Peninsula from the Yorke Peninsula. The Gulf of St. Vincent separates Yorke Peninsula from the mainland. In Spencer Gulf, colorful blue-green swirls indicate the presence of a bloom of marine plants called phytoplankton, whose brightly colored photosynthetic pigments stain the water. Water quality in the Gulf is an ongoing problem for Australia, as irrigation projects have diverted the already small flow of freshwater that empties into the Gulf. Other problems include contamination with pesticides and agricultural and residential fertilizer. On both the Eyre Peninsula and in the Victoria Territory to the east of Spencer Gulf, dark-colored rectangles show the boundaries of parks and nature preserves where the natural, drought-tolerant vegetation thrives.

    At Geoscience Australia, we are upgrading our gravity and magnetic modeling tools to provide new insights into the composition, properties, and structure of the subsurface. The scale of the investigations varies from the size of tectonic plates to the size of a mineral prospect. To accurately model potential field data at all of these scales, we require modeling software that can operate in both spherical and Cartesian coordinate frameworks. The models are in the form of a mesh, with spherical prismatic (tesseroid) elements for spherical coordinate models of large volumes, and rectangular prisms for smaller volumes evaluated in a Cartesian coordinate framework. The software can compute the forward response of supplied rock property models and can perform inversions using constraints that vary from weak generic smoothness through to very specific reference models compiled from various types of "hard facts" (i.e., surface mapping, drilling information, crustal seismic interpretations). To operate efficiently, the software is being specifically developed to make use of the resources of the National Computational Infrastructure (NCI) at the Australian National University (ANU). The development of these tools is been carried out in collaboration with researchers from the Colorado School of Mines (CSM) and the China University of Geosciences (CUG) and is at the stage of advanced testing. The creation of individual 3D geological models will provide immediate insights. Users will also be able to combine models, either by stitching them together or by nesting smaller and more detailed models within a larger model. Comparison of the potential field response of a composite model with the observed fields will give users a sense of how comprehensively these models account for the observations. Users will also be able to model the residual fields (i.e., the observed minus calculated response) to discover features that are not represented in the input composite model.

    The effects of production practices on the relative abundance of springtails (Collembola) in irrigated cotton fields of northern New South Wales (NSW) were studied over 2 yr to examine effects of farm management on these decomposer organisms. Pitfall trapping and soil core extraction was undertaken in both pseudoreplicated plots within whole fields on cotton farms and on experimental replicate plots of Envirofeast cotton and Lucerne. The relative abundance of surface-active springtails in cotton rows and densities of soil species from the rhizosphere were calculated. Twenty-three species of Collembola were collected from 5 fields, 19 in pitfall traps, and 11 in soil cores. Five species, Setogaster sp., Proisotoma minuta, Entomobrya unostrigata, Entomobrya multifasciata grp, and Lepidobrya sp. were numerically dominant on the ground at 86-96% of individuals and Mesaphorura sp., Folsomides parvulus, and Hemisotoma thermophila grp dominant in the soil. Native grassland samples contained 15 species of which a probable 10 were native and 8 were not found in cotton. Nineteen species of the 24 species identified from cotton were predominantly fungal feeders. Highest catches of Collembola occurred after flowering and soil Collembola increased with depth and during cotton growth on unsprayed plots but decreased on sprayed plots. Surface soil moistures affected daily catch rates with decomposing residues, crop stage, predator abundance, and season as secondary factors. Insecticide (endosulfan, pyrethroid, carbamate, and organophosphate) and predator effects were either negligible or unclear depending on the factor involved. Springtails appear to be predominately food limited during times of adequate soil moisture in cotton fields.

    The Newer Volcanics Province (NVP) is a Pliocene to Recent intra-plate basaltic volcanic field (BVF) that has formed in a compressive tectonic setting (σv < σhmin < σHmax) and is not readily attributed to a single geodynamic process. A comprehensive spatial analysis of both monogenetic eruption centres and coeval vents of the NVP constrain factors that control the distribution and emplacement of volcanoes. A point-set of 434 eruption centres totalling 726 vents are divided into three geographical sub-provinces for analysis. Kernel density estimation and Poisson nearest neighbour analysis are used to scrutinize the distribution of eruption centres. A simple and novel fitted regression line method is used to determine the orientation of coeval vents, and Hough transform and two-point azimuth methods are used to identify alignments and alignment trends between eruption centres. The distribution of eruption centres and their relative spatial density corresponds with the extent of thinner lithosphere. Eruption centres of the NVP have a clustered distribution whilst smaller sub-sets of eruption centres are distributed more uniformly. The main alignment trends between coeval vents related to individual dikes and between eruption centres related to successive temporally discrete dikes are primarily oriented nearly parallel with pre-existing crustal fault trends. The frequency of volcanic alignments shows faults oriented nearly parallel to the orientation of the regional maximum horizontal compressive stress (σ1) are favourably utilised by intrusions over other fault trends. The depth from which pre-existing faults facilitate dike propagation is not constrained. We interpret they are likely important in preventing dikes from stalling and forming sills under a compressive stress field in the case of the NVP. It is also observed that coeval vent alignments are more strongly aligned in areas overlying consolidated basement relative to areas of poorly consolidated basin

    In 2006, the government in the state of Victoria, Australia, mandated the rollout of smart meters in Victoria, which effectively removed a whole population's ability to avoid exposure to human-made high-frequency nonionizing radiation. This issue appears to constitute an unprecedented public health challenge for Victoria. By August 2013, 142 people had reported adverse health effects from wireless smart meters by submitting information on an Australian public Web site using its health and legal registers. The study evaluated the information in the registers to determine the types of symptoms that Victorian residents were developing from exposure to wireless smart meters. In this case series, the registers' managers eliminated those cases that did not clearly identify the people providing information by name, surname, postal address, and/or e-mail to make sure that they were genuine registrants. Then they obtained consent from participants to have their deidentified data used to compile the data for the case series. The author later removed any individual from outside of Victoria. The study included 92 residents of Victoria, Australia. The author used her medical experience and judgment to group symptoms into clinically relevant clusters (eg, pain in the head was grouped with headache, tinnitus was grouped with ringing in the ears). The author stayed quite close to the wording used in the original entries. She then calculated total numbers and percentages for each symptom cluster. Percentages were rounded to the nearest whole number. The most frequently reported symptoms from exposure to smart meters were (1) insomnia, (2) headaches, (3) tinnitus, (4) fatigue, (5) cognitive disturbances, (6) dysesthesias (abnormal sensation), and (7) dizziness. The effects of these symptoms on people's lives were significant. Review of some key studies, both recent and old (1971), reveals that the participants' symptoms were the same as those reported by people exposed to

    A number of viruses from the genera Furovirus, Hordeivirus and Rymovirus are known to infect and damage the four major temperate cereal crops, wheat, barley, sorghum and oats. Currently, there is no active testing in Australia for any of these viruses, which pose a significant biosecurity threat to the phytosanitary status of Australia's grains industry. To address this, broad spectrum PCR assays were developed to target virus species within the genera Furovirus, Hordeivirus and Rymovirus. Five sets of novel genus-specific primers were designed and tested in reverse-transcription polymerase chain reaction assays against a range of virus isolates in plant virus diagnostic laboratories in both Australia and New Zealand. Three of these assays were then chosen to screen samples in a three-year survey of cereal crops in western Victoria, Australia. Of the 8900 cereal plants screened in the survey, all were tested free of furoviruses, hordeiviruses and rymoviruses. To date, there were no published genus-specific primers available for the detection of furoviruses, hordeiviruses and rymoviruses. This study shows for the first time a broad-spectrum molecular test being used in a survey for exotic grain viruses in Australia. Results from this survey provide important evidence of the use of this method to demonstrate the absence of these viruses in Victoria, Australia. The primer pairs reported here are expected to detect a wide range of virus species within the three genera.

    A method for subsurface recognition of blind geological bodies is presented using combined surface constraints and 3-D structural modelling that incorporates constraints from detailed mapping, and potential-field inversion modelling. This method is applied to the Mount Painter Province and demonstrates that addition of low density material is required to reconcile the gravity signature of the region. This method may be an effective way to construct 3-D models in regions of excellent structural control, and can be used to assess the validity of surface structures with 3-D architecture. Combined geological and potential-field constrained inversion modelling of the Mount Painter Province was conducted to assess the validity of the geological models of the region. Magnetic susceptibility constrained stochastic property inversions indicates that the northeast to southwest structural trend of the relatively magnetic meta-sedimentary rocks of the Radium Creek Group in the Mount Painter Inlier is reconcilable with the similar, northeast to southwest trending positive magnetic anomalies in the region. Radium Creek Group packages are the major contributor of the total magnetic response of the region. However field mapping and the results of initial density constrained stochastic property inversion modelling do not correlate with a large residual negative gravity anomaly central to the region. Further density constrained inversion modelling indicates that an additional large body of relatively low density material is needed within the model space to account for this negative density anomaly. Through sensitivity analysis of multiple geometrical and varied potential-field property inversions, the best-fitting model records a reduction in gravity rms misfit from 21.9 to 1.69 mGal, representing a reduction from 56 to 4.5 per cent in respect to the total dynamic range of 37.5 mGal of the residual anomaly. This best-fitting model incorporates a volumetrically significant source

    Rhizobacteria closely related to two recently described species of pseudomonads, Pseudomonas brassicacearum and Pseudomonas thivervalensis, were isolated from two geographically distinct wheat field soils in South Australia. Isolation was undertaken by either selective plating or immunotrapping utilizing a polyclonal antibody raised against P. brassicacearum. A subset of 42 isolates were characterized by amplified 16S ribosomal DNA restriction analysis (ARDRA), BIOLOG analysis, and gas chromatography-fatty acid methyl ester (GC-FAME) analysis and separated into closely related phenetic groups. More than 75% of isolates tested by ARDRA were found to have >95% similarity to either Pseudomonas corrugata or P. brassicacearum-P. thivervalensis type strains, and all isolates had >90% similarity to either type strain. BIOLOG and GC-FAME clustering showed a >70% match to ARDRA profiles. Strains representing different ARDRA groups were tested in two soil types for biological control activity against the soilborne plant pathogen Gaeumannomyces graminis var. tritici, the causative agent of take-all of wheat and barley. Three isolates out of 11 significantly reduced take-all-induced root lesions on wheat plants grown in a red-brown earth soil. Only one strain, K208, was consistent in reducing disease symptoms in both the acidic red-brown earth and a calcareous sandy loam. Results from this study indicate that P. brassicacearum and P. thivervalensis are present in Australian soils and that a level of genetic diversity exists within these two novel species but that this diversity does not appear to be related to geographic distribution. The result of the glasshouse pot trial suggests that some isolates of these species may have potential as biological control agents for plant disease. PMID:10742249

    The Proterozoic Mt Isa inlier ( ˜50,000 km2) in NW Queensland, Australia, underwent a complex tectonothermal history involving multiple episodes of intracontinental rifting, sedimentation, and magmatism that culminated in the Isan Orogeny (1590-1500 Ma) where strong E-W shortening led to compressional inversion of former rift basins. The resulting metamorphic complex of subgreenschist to amphibolite facies assemblages is disrupted by brittle, late-orogenic (1500-1450 Ma?) strike-slip faults. The faults occur in two mutually cross-cutting sets; a set of dextral strike-slip faults striking NE-SW to NNE-SSW with offsets <20 km, and a conjugate set of sinistral faults striking NW-SE to NNW-SSE. The two contemporaneous fault sets therefore lie at +/-45-60° to inferred E-W maximum compression, approaching the expected lock-up angle for 'Byerlee' friction coefficients. The faults commonly outcrop as linear blade-like ridges extending for many kilometres across the semi-arid terrain. Transects across the NE-SW Fountain Range and Overlander Faults which crosscut Corella Formation amphibolite facies assemblages and granites have shown that the fault zones are about 100 m in width with a composite brittle fabric comprising: (1) subvertical silicified cataclastic shear zones (cataclasites plus microbreccias containing vein fragments); (2) innumerable subvertical quartz-veins (cm to m thickness) lying subparallel to the principal shear zones (some retain purely dilational textures; others are multiply recemented fault-breccias with wallrock fragments); (3) highly irregular non-systematic veins; and (4) a systematic set of predominantly extensional, steep planar quartz veins oriented 080-120° at moderate angles to the main faults. Mutual cross-cutting relationships occur between all structural components, indicating broad contemporaneity. Recorded dextral separations along shear fracture components are commonly of the order of 1-10 cm, consistent with small-moderate seismic

    South-eastern Australia is generally regarded as one of the world's most fire-prone environments because of its high temperatures, low rainfall and flammable native Eucalyptus forests. Modifications to the landscape by fire can lead to significant changes to erosion rates and hydrological processes. Debris flows in particular have been recognised as a process which increases in frequency as a result of fire. This study used a debris flow event in the east Upper Ovens occurred on the 28th of February 2013 as a case study for analysing sediment transport processes and connectivity of sediment sources and sinks. Source areas were identified using a 15 cm resolution areal imagery and a logistic regression model was made based on fire severity, aridity index and slope to predict locations of source areas. Deposits were measured by making cross-sections using a combination of a differential GPS and a total station. In total 77 cross-sections were made in a 14.1 km2 sub-catchment and distributed based on channel gradient and width. A more detailed estimation was obtained by making more cross-sections where the volume per area is higher. Particle size distribution between sources and sink areas were obtained by combination of field assessment, photography imagery analyses and sieve and laser diffraction. Sediment was locally eroded, transported and deposited depending on factors such as longitude gradient, stream power and the composition of bed and bank material. The role of headwaters as sediment sinks changed dramatically as a result of the extreme erosion event in the wildfire affected areas. Disconnected headwaters became connected to low order streams due to debris flow processes in the contributing catchment. However this redistribution of sediment from headwaters to the drainage network was confined to upper reaches of the Ovens. Below this upper part of the catchment the event resulted in redistribution of sediment already existing in the channel through a

    In recent years, the global incidence of Fasciola hepatica (liver fluke) infections exhibiting resistance to triclabendazole (TCBZ) has increased, resulting in increased economic losses for livestock producers and threatening future control. The development of TCBZ resistance and the worldwide discovery of F. hepatica population diversity has emphasized the need to further understand the genetic structure of drug susceptible and resistant Fasciola populations within Australia. In this study, the genetic diversity of liver flukes was estimated by sequencing mitochondrial DNA (mtDNA) encoding the NAD1 (530 bp) and COX1 (420 bp) genes of 208 liver flukes (F. hepatica) collected from three populations: field isolates obtained from abattoirs from New South Wales (NSW) and Victoria (Vic); three TCBZ-resistant fluke populations from NSW and Victoria; and the well-established TCBZ-susceptible Sunny Corner laboratory isolate. Overall nucleotide diversity for all flukes analysed of 0.00516 and 0.00336 was estimated for the NAD1 and COX1 genes respectively. Eighteen distinct haplotypes were established for the NAD1 gene and six haplotypes for the COX1 gene, resulting in haplotype diversity levels of 0.832 and 0.482, respectively. One field isolate showed a similar low level of haplotype diversity as seen in the Sunny Corner laboratory isolate. Analysis of TCBZ-resistant infrapopulations from 3 individual cattle grazing one property revealed considerable sequence parasite diversity between cattle. Analysis of parasite TCBZ-resistant infrapopulations from sheep and cattle revealed haplotypes unique to each host, but no significant difference between parasite populations. Fst analysis of fluke populations revealed little differentiation between the resistant and field populations. This study has revealed a high level of diversity in field and drug resistant flukes in South-Eastern Australia.

    Australia's earliest-known planispheres were made by a Sydney amateur astronomer named George Butterfield in 1870 and 1877, although a similar but more crudely-made 'noctural dial' was created by Philip Parker King in 1852. This paper discusses these pioneering endeavours, other nineteenth century attempts to popularise astronomy, and the prevailing astronomical climate in Australia at that time.

  3. Field Evaluation of Melolure, a Formate Analogue of Cuelure, and Reassessment of Fruit Fly Species Trapped in Sydney, New South Wales, Australia.

    In Australia, tephritids are usually attracted to either cuelure or methyl eugenol. Methyl eugenol is a very effective lure, but cuelure is less effective likely due to low volatility. A new formate analogue of cuelure, melolure, has increased volatility, resulting in improved efficacy with the melon fruit fly, Bactrocera cucurbitae Coquillett. We tested the efficacy of melolure with fruit fly species in Sydney as part of the National Exotic Fruit Fly Monitoring programme. This monitoring programme has 71 trap sites across Sydney, with each trap site comprising separate Lynfield traps containing either cuelure, methyl eugenol, or capilure lure. In 2008, an additional Lynfield trap with melolure plugs was added to seven sites. In 2009 and 2010, an additional Lynfield trap with melolure wicks was added to 11 trap sites and traps were monitored fortnightly for 2 yr. Capture rates for melolure traps were similar to cuelure traps for Dacus absonifacies (May) and Dacus aequalis (Coquillet), but melolure traps consistently caught fewer Bactrocera tryoni (Froggatt) than cuelure traps. However, trap sites with both a cuelure and melolure traps had increased capture rates for D. absonifacies and D. aequalis, and a marginally significant increase for B. tryoni. Melolure plugs were less effective than melolure wicks, but this effect may be related to lure concentration. The broader Bactrocera group species were attracted more to cuelure than melolure while the Dacus group species were attracted more to melolure than cuelure. There is no benefit in switching from cuelure to melolure to monitor B. tryoni, the most important fruit fly pest in Australia.

    Abstract We report the clinical course and physiologic and anesthetic data for a case series of 76 free-ranging dromedary camels (Camelus dromedarius) chemically restrained, by remote injection from a helicopter, in the rangelands of Western Australia and South Australia, 2008-11, to attach satellite-tracking collars. Fifty-five camels were successfully anesthetized using medetomidine-ketamine (MK, n=27) and medetomidine-ketamine-butorphanol (MKB, n=28); the induction of anesthesia in 21 animals was considered unsuccessful. To produce reliable anesthesia for MK, medetomidine was administered at 0.22 mg/kg (± SD=0.05) and ketamine at 2.54 mg/kg (± 0.56), and for MKB, medetomidine was administered at 0.12 mg/kg (± 0.05), ketamine at 2.3 mg/kg (± 0.39), and butorphanol at 0.05 mg/kg (± 0.02). Median time-to-recumbency for MKB (8.5 min) was 2.5 min shorter than for MK (11 min) (P=0.13). For MK, the reversal atipamezole was administered at 0.24 mg/kg (± 0.10), and for MKB, atipamezole was administered at 0.23 mg/kg (± 0.13) and naltrexone at 0.17 mg/kg (± 0.16). Median time-to-recovery was 1 min shorter for MK (5 min) than MKB (6 min; P=0.02). Physiologic parameters during recumbency were not clinically different between the two regimes. Both regimes were suitable to safely anesthetize free-ranging camels; however, further investigation is required to find the safest, most consistent, and logistically practical combination.

    In this study, we compared the efficacy of the newly available BG-Sentinel with an established "gold standard,", the CDC Backpack Aspirator, and a CO2-baited EVS trap for the collection of Aedes aegypti (L.) in Cairns, Australia. BG-Sentinels collected significantly more (P = 0.017) female Ae. aegypti (mean per collection, 1.92 +/- 0.39) than both the CDC Backpack Aspirator (1.00 +/- 0.35) and the EVS trap (0.71 +/- 0.27). Male-only and combined male-female Ae. aegypti collections for th BG-Sentinel and the CDC Backpack Aspirator were also greater than EVS trap collections. The CDC Backpack Aspirator and the BG-Sentinel captured proportionally fewer females compared with the EVS trap. The BG-Sentinel was the most Ae. aegypti specific collection method. The CDC Backpack Aspirator collected proportionally more bloodfed Ae. aegypti than the other methods, which collected a greater proportion of nullipars. The data presented here will aid researchers in deciding what Ae. aegypti sampling device best suits their needs. BG-Sentinels and CDC Backpack Aspirators should be considered as alternatives to human-bait collections for Ae. aegypti sampling.

  9. ESO and Australia to Discuss Future Collaboration

    NASA Astrophysics Data System (ADS)

    1996-01-01

    For some time, the astronomical community in Australia has expressed interest in closer ties to ESO. One of the main reasons is the construction of the ESO Very Large Telescope (VLT), of which the first 8.2 m unit telescope is scheduled for completion less than 2 years from now. The science of astronomy and astrophysics is highly developed in Australia and researchers in this country already have access to several excellent observational facilities, notably the 3.9 m optical telescope at the Siding Spring Observatory, the 64 m Parkes radio telescope and the Australia Telescope, one of the largest radio interferometric instruments in the world. On this important background, it is understandable that there is now an expressed desire among Australian scientists to participate in the VLT project and thus to partake in the front-line science and technology at the world's largest optical telescope. The related moves have been channelled through the Australian National Committee for Astronomy and the first formal contacts between Australia and ESO were made 1/2 year ago, cf. ESO Press Release 07/95 of 8 June 1995. ESO has welcomed the prospects of a closer, future collaboration with Australia, in particular because of the acknowledged expertise in that country within the important field of optical interferometry, a main feature of the VLT project. The Australian Government recently announced a new master plan 'Innovate Australia' which aims at updating and further development of science and technology in this country. It incorporates important support towards the modernization of the Australia Telescope, and certain funds are also foreseen for participation in international projects within the field of astronomy and astrophysics. At the request of the Australian Government, a high-ranking Australian delegation will visit the ESO Headquarters in Garching (Germany) in order to explore with ESO in some detail possible modes of future collaboration. This visit will take place

    1996-04-01

    A 3.1-3.3 Ga Mid-Archean accretionary complex has been identified in the Cleaverville area, Pilbara granite-greenstone terrain, Western Australia, by using a well-defined duplex structure and by reconstructing the oceanic plate stratigraphy. Archean mid-oceanic ridge basalts (AMORBs) which are part of this sequence were selected for detailed petrochemical analysis to infer Archean divergent plate tectonic process. The Cleaverville AMORBs are low-K tholeiites which tend to be richer in FeO ∗ than modern MORBs. Abundance ratios of most incompatible elements such as REE, Ti, Y and Zr are chondritic. Neither Nb/Zr nor P/Zr suggest partitioning into the metallic core before the middle Archean. Estimated Mg ∗ values of the mantle source is about 85, and is lower than that of 89-92 modern MORBs. The Cleaverville AMORBs are considered to have been produced by partial melting at a pressure and temperature of 2.5 GPa and 1425 °C of a Fe-rich mantle peridotite (Mg ∗ value = 85.0). Potential mantle temperature (PMT) of the Earth of the mid-oceanic ridge at this time 3.1-3.3 Ga was estimated from the above constraints on the Cleaverville AMORBs to be 1400 °C. If the Cleaverville example is representative of Archean plate boundary processes at spreading ridges, the PMT was about 120 °C higher than today and extensive partial melting of adiabatically rising mantle material would have been initiated at 90 km depth. Net production of partial melt at the AMOR axis was equivalent to 15-20 km thickness of oceanic crust (roughly 2-3 times thicker than today).

  12. Modelling the impacts of climate change on wheat yield and field water balance over the Murray-Darling Basin in Australia

    Wang, Jing; Wang, Enli; Liu, De Li

    2011-06-01

    The study used a modelling approach to assess the potential impacts of likely climate change and increase in CO2 concentration on the wheat growth and water balance in Murray-Darling Basin in Australia. Impacts of individual changes in temperature, rainfall or CO2 concentration as, well as the 2050 and 2070 climate change scenarios, were analysed. Along an E-W transect, wheat yield at western sites (warmer and drier) was simulated to be more sensitive to temperature increase than that at eastern sites; along the S-N transect, wheat yield at northern warmer sites was simulated to be more sensitive to temperature increase, within 1-3°C temperature increase. Along the E-W and S-N transects, wheat at drier sites would benefit more from elevated [CO2] than at wetter sites, but more sensitive to the decline in rainfall. The increase in temperature only did not have much impact on water balance. Elevated [CO2] increased the drainage in all the sites, whilst rainfall reduction decreased evapotranspiration, runoff and drainage, especially at drier sites. In 2050, wheat yield would increase by 1-10% under all climate change scenarios along the S-N transect, except for the northernmost site (Dalby). Along the E-W transect, the most obvious increase of wheat yields under all climate change scenarios occurred in cooler and wetter eastern sites (Yass and Young), with an average increase rate of 7%. The biggest loss occurred at the driest sites (Griffith and Swan Hill) under A1FI and B2 scenarios, ranging from -5% to -16%. In 2070, there would be an increased risk of yield loss in general, except for the cool and wet sites. Water use efficiency was simulated to increase at most of the study sites under all the climate change scenarios, except for the driest site. Yield variability would increase at drier sites (Ardlethan, Griffith and Swan Hill). Soil types would also impact on the response of wheat yield and water balance to future climate change.

  13. Surface and sub-surface anatomy of the landscape: integrating Unmanned Aerial Vehicle Structure from Motion (UAV-SfM) and Ground Penetrating Radar (GRP) to investigate sedimentary features in the field. - an example from NW Australia

    Geomorphology is confronted by the challenge of reconstructing landscape features at appropriate scales, resolution and accuracy, that allows meaningful analysis of environmental processes and their implications. Field geomorphology offers a discrete snapshot (i.e. one or two field campaigns) to reconstruct how features have changed, evolved or responded over time. We explore the application of an emerging photogrammetry technique called Structure-from-Motion (SfM), which uses multiple photographs of the same feature (but taken at different locations) to create high-accuracy three-dimensional models of surface of sedimentary fans formed by extreme wave events. This approach is complimented by investigation of the sub-surface morphology using Ground Penetrating Radar (GPR). Using an UAV "octocopter", we captured 1208 photos with a DSLR camera (Canon EoS-M) at the height of 50m with a ground pixel resolution of 9mm, above a cyclone wash-over fan in the Exmouth Gulf (Western Australia) that measured about 500m inland by 300m wide. Based on 38 ground control point targets (with between 4 and 45 individual photographs per target) the SfM surface had an absolute total (XYZ) accuracy of 51mm (39mm X, 29mm Y and 14mm Y), based on RTK-DGPS surveying from a local ground reference station (with an absolute AUSPOS accuracy of 57mm X, 6mm Y, 50mm Z to AHD) and an overall relative point accuracy of 7mm. A sparse point cloud of over 5.5 million data points was generated using only points with a reconstruction accuracy of <50mm, before spectral unsupervised classification (RGB colour of each XYZ pixel) using K-Means clustering within Python. The output was then manually classified into ground and non-ground points, and the geostatistical analyst functionality of ArcGIS used to produce a final bare-earth DEM. This approach has allowed the study team to economically collect an unprecedented high-resolution and accuracy topographic model of this feature to compliment on

    With consultations having been held across Australia this year as part of the process of developing a new National Alcohol Strategy, it seemed timely to invite my colleagues from the National Drug Research Institute who are experts in the alcohol field to write this Harm Reduction Digest. The authors have canvassed a range of alcohol policy options and discussed their effectiveness in reducing harm for what is arguably Australia's number one drug problem. Australia's response to alcohol and other drug problems has, historically, been based on 'harm minimization--incorporating supply reduction, demand reduction and harm reduction'. At this time where the policy options for alcohol are being set for the next 5 years in a climate of 'small government', removing restrictions of 'fair competition' in business and a belief in the free market, what does the research have to say about recommended policies and strategies to reduce alcohol-related harm?

    No single issue has dominated health practitioners' ethical debates in 2014 in Australia, but a controversial decision on gene patenting and the media focus on "Dr. Death," euthanasia campaigner Dr. Philip Nitschke, have given new life to these two familiar (and global) debates. Currently a dying with dignity bill, drafted by the Australian Green Party, is under examination. The Senate inquiry into the bill received more than 663 submissions, with 57% opposed and 43% in support of the bill, which has now been referred to a Senate committee. Will this be another of Australia's failed attempts to legalize euthanasia? The trial of Dr. Nitschke begins on November 10, 2014.

This scene was acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra satellite. (Please note that this scene has not been reprojected.) Cyclone Chris is one of the most powerful storms ever to hit Australia. Initially, the storm contained wind gusts of up to 200 km per hour (125 mph), but shortly after making landfall it weakened to a Category 4 storm. Meteorologists expect the cyclone to weaken quickly as it moves further inland.

  4. Australia: a continuing genocide?

    PubMed

    Short, Damien

    2010-01-01

    Debates about genocide in Australia have for the most part focussed on past frontier killings and child removal practices. This article, however, focuses on contemporary culturally destructive policies, and the colonial structures that produce them, through the analytical lens of the concept of genocide. The article begins with a discussion of the meaning of cultural genocide, locating the idea firmly in Lemkin's work before moving on to engage with the debates around Lemkin's distinction between genocide and cultural 'diffusion.' In contrast to those scholars who prefer the word 'ethnocide,' the underlying conceptual contention is that the term 'cultural genocide' simply describes a key method of genocide and should be viewed, without the need for qualification, as genocide. While direct physical killing and genocidal child removal practices may have ceased in Australia, some indigenous activists persuasively contend that genocide is a continuing process in an Australia that has failed to decolonise. Concurring with these views the article argues that the contemporary expression of continuing genocidal relations in Australia can be seen principally, and perversely, in the colonial state's official reconciliation process, native title land rights regime and the recent interventionist 'solutions' to indigenous 'problems' in the Northern Territory.

  8. Australia's nuclear graveyard

    Milliken, R.

    1987-04-01

    Britain and Australia have become locked in a battle of wills and wits over a nuclear legacy that is now more than 30 years old. At stake is the issue of who will pay to clean up a stretch of the central Australian outback where at least 23 kilograms of plutonium are buried in nuclear graveyards or scattered in fine particles on the ground. The plutonium was left there after a series of British nuclear weapons tests in the 1950s and 1960s. The cost of cleaning it up today, and rendering the ground safe the the Aborigines who claim it as their tribal homeland, has been estimated at up to $158 million. Australia's minister for resources, Senator Gareth Evans, went to London in October 1986 to try to involve the British in the cleanup. But Britain is still taking the stand that it had discharged any obligations on this score long ago. This question is at the heart of controversy that began mounting in the late 1970s over the British nuclear tests. It was then that Aborigines and test veterans from Britain and Australia started alleging that they had been exposed to unduly high doses of radiation. Clearly, the nuclear tests, which began as a political exercise between Britain and Australia more than 30 years ago, seem destined to remain the source of much legal, diplomatic, and financial fallout between the two countries for a long time to come.

    1994-01-01

    Australia had a population of 17.6 million in 1991. In 1992, Australia's population grew at the rate of 1.06%, 0.8% due to natural increase and 0.26% from immigration. The recent Australian Bureau of Statistics Report estimates that it will grow to 18.9 million by the end of the century and 23.1 million by 2025, assuming fertility remains at current levels and net migration stabilizes at 70,000 per annum from the year 2000. The World Bank estimates that Australia's population will stabilize at 25 million some time in the future. Since Australia's politicians and economists fail to understand that the country already has a large enough population, no national population policy has been declared. The Department of Immigration and Ethnic Affairs, responsible for all population issues, gives no thought to the long-term environmental consequences of the rapidly growing population and determines the annual migrant intake simply on the basis of the nation's economic needs, demands from new immigrants for admission of their next of kin, and humanitarian considerations with regard to refugees. Population growth in Australia needs to be checked as soon as possible. Reducing the annual migrant intake to below 50,000, Australia could achieve a stable population of approximately 23 million by 2040; the annual intake of 150,000 immigrants will grow the population to 37 million. The total fertility rate (TFR) has been below replacement level since 1976, but the population's skewed age distribution will cause it to continue to grow through natural increase at the current rate of approximately 0.8% per year for some time to come. Improving educational opportunities for women and ensuring that all have ready access to modern contraception could help produce a further decline in TFR. Moreover, education about contraception must be made a part of every school curriculum. Steps taken now may avert any future flood of millions of ecological refugees from Southeast Asia, particularly

    STS035-501-007 (2-10 Dec. 1990) --- The STS-35 crewmembers aboard the Earth-orbiting Space Shuttle Columbia photographed this view of the Arid Simpson Desert of Australia with a handheld Rolleiflex camera. Lake Eyre is normally dry; however, the STS-35 crew was able to recognize water in the lowest parts of the lake (dark pink area) and possibly in Lake Blanche east of Lake Eyre. Lake Frome lies in the distance separated from Lake Torrens (top right) by dark hills of Flinders Range. The Finke River (bottom left to middle) flows into the Eyre basin from the northwest. Although it is the largest river entering the basin, Finke's floods seldom reach Lake Eyre. The dark brown patch in the foreground is an area of ancient, brown lateritic soils partly covered by dunes.

  15. How should Australia regulate voluntary euthanasia and assisted suicide?

    2012-12-01

    This article invites consideration of how Australia should regulate voluntary euthanasia and assisted suicide. It attempts to pose this question as neutrally as possible, acknowledging that both prohibition and legalisation of such conduct involve decisions about regulation. It begins by charting the wider field of law at the end of life, before considering the repeated, but ultimately unsuccessful, attempts at law reform in Australia. The situation in Australia is contrasted with permissive jurisdictions overseas where voluntary euthanasia and/or assisted suicide are lawful. The authors consider the arguments for and against legalisation of such conduct along with the available empirical evidence as to what happens in practice both in Australia and overseas. The article concludes by outlining a framework for deliberating on how Australia should regulate voluntary euthanasia and assisted suicide. It asks a threshold question of whether such conduct should be criminal acts (as they presently are), the answer to which then leads to a range of possible regulatory options.

  16. A new dasyurid marsupial from Kroombit Tops, south-east Queensland, Australia: the Silver-headed Antechinus, Antechinus argentus sp. nov. (Marsupialia: Dasyuridae).

    Antechinus argentus sp. nov. is currently only known from the plateau at the eastern escarpment of Kroombit Tops National Park, about 400km NNW of Brisbane and 60km SSW of Gladstone, south-east Queensland, Australia. Antechinus flavipes (Waterhouse) is also known from Kroombit Tops NP, 4.5km W of the nearest known population of A. argentus; A. mysticus Baker, Mutton and Van Dyck has yet to be found within Kroombit Tops, but is known from museum specimens taken at Bulburin NP, just 40km ESE, as well as extant populations about 400km to both the south-east and north-west of Kroombit NP. A. argentus can be easily distinguished in the field, having an overall silvery/grey appearance with much paler silver feet and drabber deep greyish-olive rump than A. flavipes, which has distinctive yellow-orange toned feet, rump and tail-base; A. argentus fur is also less coarse than that of A. flavipes. A. argentus has a striking silver-grey head, neck and shoulders, with pale, slightly broken eye-rings, which distinguish it from A. mysticus which has a more subtle greyish-brown head, pale buff dabs of eyeliner and more colourful brownish-yellow rump. Features of the dentary can also be used for identification: A. argentus differs from A. flavipes in having smaller molar teeth, as well as a narrower and smaller skull and from A. mysticus in having on average a narrower snout, smaller skull and dentary lengths and smaller posterior palatal vacuities in the skull. A. argentus is strongly divergent genetically (at mtDNA) from both A. flavipes (9.0-11.2%) and A. mysticus (7.2-7.5%), and forms a very strongly supported clade to the exclusion of all other antechinus species, in both mtDNA and combined (mtDNA and nDNA) phylogenies inferred here. We are yet to make detailed surveys in search of A. argentus from forested areas to the immediate east and north of Kroombit Tops. However, A. mysticus has only been found at these sites in low densities in decades past and not at all in several

    Nurses in the field of wound care are increasingly being courted by the wound industry. A survey regarding nurses' perceptions and participation in pharmaceutical marketing was conducted. Based on existing instruments, a standardized questionnaire (39 items, 5-point Likert scale) was developed. It was sent electronically and by mail to all nursing members of the Austrian Society for Vascular Care (ÖGvP), the German Wound Healing Society (DGfW e. V.) and the Swiss Association for Wound Care (SAfW). 178 nurses participated in the survey (75 % women; aged 27 - 70 years [median 45], 0 - 40 years [median 9] practice in the area of the wound care). Only about one fourth of the respondents (23,0 %) did not participate in pharmaceutical marketing last year. Generally small gifts were more frequently received than expensive gifts. Most of the nurses valued inexpensive gifts, educational gifts and gifts with patient benefit as appropriate. The majority of respondents consider themselves as less influenceable in decision making, compared to physicians. The behavior and attitude of nurses are ambivalent. The occurrence of conflict of interest is partly justified by perceived patient benefit. Lack of knowledge about the topic and social desirability could be the cause of an uncritical attitude. For a more critical approach education and ethical standards are necessary.

    Tasmania is important for understanding Quaternary climatic change because it is one of only three areas that experienced extensive mid-latitude Southern Hemisphere glaciation and it lies in a dominantly oceanic environment at a great distance from Northern Hemisphere ice sheet feedbacks. We applied exposure dating using 36Cl to an extensive sequence of moraines from the last glacial at Mt. Field, Tasmania. Glaciers advanced at 41-44 ka during Marine oxygen Isotope Stage (MIS) 3 and at 18 ka during MIS 2. Both advances occurred in response to an ELA lowering greater than 1100 m below the present-day mean summer freezing level, and a possible temperature reduction of 7-8°C. Deglaciation was rapid and complete by ca. 16 ka. The overall story emerging from studies of former Tasmanian glaciers is that the MIS 2 glaciation was of limited extent and that some glaciers were more extensive during earlier parts of the last glacial cycle.

  19. Constrained potential field modeling of the crustal architecture of the Musgrave Province in central Australia: Evidence for lithospheric strengthening due to crust-mantle boundary uplift

    NASA Astrophysics Data System (ADS)

    Aitken, Alan R. A.; Betts, Peter G.; Weinberg, Roberto F.; Gray, Daniel

    2009-12-01

    We image the crustal architecture of the Musgrave Province with petrophysically constrained forward models of new potential field data. These models image divergent shallow-dipping crustal scale thrusts that, at depth, link with an axial zone defined by steeper, lithospheric scale transpressional shear zones. They also show that to permit a near-surface density distribution that is consistent with petrophysical and geological observations, approximately 15-20 km of crust-mantle boundary uplift is necessary beneath the axial zone. The long-term preservation of this crust-mantle boundary offset implies a change from relatively weak lithosphere to relatively strong lithosphere during the intraplate Petermann Orogeny. To explain this, we propose a model in which uplift of the axial zone of the orogen leads to local lithospheric strengthening as a result of the uplift of mantle rocks into the lower crust, coupled with long-term lithospheric cooling due to the erosion of a radioactive upper crust. Brace-Goetze lithospheric strength models suggest that these processes may have increased the integrated strength of the lithosphere by a factor of 1.4-2.8. Because of this strengthening, this system is self-limiting, and activity will cease when lithospheric strength is sufficient to resist external forces and support isostatic imbalances. A simple force-balance model demonstrates that the force required to uplift the axial zone is tectonically reasonable and that the system can subsequently withstand significant tensional forces. This example shows that crust-mantle boundary uplift coupled with reduced crustal heat production can profoundly affect the long-term strength of the continental lithosphere and may be a critical process in the tectonic stabilization of intraplate regions.

    PubMed

    Ruddock, P

    1999-01-01

    In an address to the Australian Population Association Biennial Conference during October 1998, the Immigration and Multicultural Affairs Minister Philip Ruddock argued that neither the zero net overseas migration policy nor the massive boost in immigration are in the national interest of Australia. Environmental groups generally view that Australia should adopt a policy of zero net overseas migration. On the other hand, business and industry bodies consider that a substantial increase in the migration intake is needed in order to increase economic growth and to reduce the impact of an aging population. Moreover, some are concerned about population targets reaching up to 50 million in 50 years time. Thus, management of immigration policy is a difficult balancing act between competing objectives. The Minister concluded that their immigration program must operate on a totally global and nondiscriminatory basis regarding matters such as race, religion, color, and ethnic origin.

    The legal structure for the regulation of tissue banking has existed for many years. In Australia, the donation of human tissue is regulated by legislation in each of the eight States and Territories. These substantially uniform Acts were passed in the late 1970's and early 1980's, based on model legislation and underpinned by the concept of consensual giving. However, it was not until the early 1990's that tissue banking came under the notice of regulatory authorities. Since then the Australian Government has moved quickly to oversee the tissue banking sector in Australia. Banked human tissue has been deemed to be a therapeutic good under the Therapeutic Goods Act 1989, and tissue banks are required to be licensed by the Therapeutic Goods Administration and are audited for compliance with the Code of Good Manufacturing Practice- Human Blood and Tissues. In addition, tissue banks must comply with a myriad of other standards, guidelines and recommendations.

    Australian regolith materials are described, many of which are complex. Much Australian regolith dates back to the Tertiary, Mesozoic or earlier. There is a progressive change in the nature of alluvium through the Tertiary. Aridity, revealed through sand dunes and evaporites, is confined to the Quaternary. Ferricretes and silcretes are formed on lower slopes, often followed by inversion of relief. Tectonic isolation of Australia as well as climatic change is responsible for the change in the nature of terrestrial sediments since the Cretaceous.

    2005-01-01

    We estimated for Australia the number of cases, hospitalizations, and deaths due to foodborne gastroenteritis in a typical year, circa 2000. The total amount of infectious gastroenteritis was measured by using a national telephone survey. The foodborne proportion was estimated from Australian data on each of 16 pathogens. To account for uncertainty, we used simulation techniques to calculate 95% credibility intervals (CrI). The estimate of incidence of gastroenteritis in Australia is 17.2 million (95% confidence interval 14.5–19.9 million) cases per year. We estimate that 32% (95% CrI 24%–40%) are foodborne, which equals 0.3 (95% CrI 0.2–0.4) episodes per person, or 5.4 million (95% CrI 4.0–6.9 million) cases annually in Australia. Norovirus, enteropathogenic Escherichia coli, Campylobacter spp., and Salmonella spp. cause the most illnesses. In addition, foodborne gastroenteritis causes ≈15,000 (95% CrI 11,000–18,000) hospitalizations and 80 (95% CrI 40–120) deaths annually. This study highlights global public health concerns about foodborne diseases and the need for standardized methods, including assessment of uncertainty, for international comparison. PMID:16102316

  6. GNSS Antenna Calibration Facility at Geoscience Australia

    2013-12-01

    A GNSS antenna calibration facility has recently been established at Geoscience Australia. The facility includes a GEO++ robotic antenna calibration system, and an industrial robot (';KUKA'). Previous studies have highlighted the importance of accounting for the variation in antenna calibration due to the electromagnetic coupling between the antenna and monument. The reactive near-field effect has been reported to have the potential to produce a combination of a mean bias and change in periodic noise characteristics which then result in a velocity bias as well as a decrease in precision of coordinate estimates. Initially the priority of the calibration system will be to perform individual antenna calibrations for over 100 antennas purchased for high accuracy deformation surveys carried out in Western Australia, South Australia and south-east Australia. The principal aim of these deformation surveys is to detect intra-plate crustal deformation, where the magnitude of the signal is expected to be less than 1 mm/yr. The main role of the industrial robot is for research and development into GNSS algorithms and to further developments into antenna calibration. The industrial robot has a much higher payload capability of up to 60 kg. This makes it feasible to perform calibrations with a section of the monument still attached to the antenna, potentially providing a calibration which will better reflect the environment the signals are observed in. We will detail various experiments to be carried out on the industrial robot, and provide an update on the status and performance of the calibration facility.

    Space Weather Plan Australia has a draft space weather plan to drive and focus appropriate research into services that meet future industry and social needs. The Plan has three main platforms, space weather monitoring and service delivery, support for priority research, and outreach to the community. The details of monitoring, service, research and outreach activities are summarised. A ground-based network of 14 monitoring stations from Antarctica to Papua New Guinea is operated by IPS, a government agency. These sites monitor ionospheric and geomagnetic characteristics, while two of them also monitor the sun at radio and optical wavelengths. Services provided through the Australian Space Forecast Centre (ASFC) include real-time information on the solar, space, ionospheric and geomagnetic environments. Data are gathered automatically from monitoring sites and integrated with data exchanged internationally to create snapshots of current space weather conditions and forecasts of conditions up to several days ahead. IPS also hosts the WDC for Solar-Terrestrial Science and specialises in ground-based solar, ionospheric, and geomagnetic data sets, although recent in-situ magnetospheric measurements are also included. Space weather activities A research consortium operates the Tasman International Geospace Environment Radar (TIGER), an HF southward pointing auroral radar operating from Hobart (Tasmania). A second cooperative radar (Unwin radar) is being constructed in the South Island of New Zealand. This will intersect with TIGER over the auroral zone and enhance the ability of the radar to image the surge of currents that herald space environment changes entering the Polar Regions. Launched in November 2002, the micro satellite FEDSAT, operated by the Cooperative Research Centre for Satellite Systems, has led to successful space science programs and data streams. FEDSAT is making measurements of the magnetic field over Australia and higher latitudes. It also carries a

    Australia, like all polio-free countries and regions, remains at risk of a wild poliovirus importation until polio is eradicated globally. The most probable route of importation will be through a traveller arriving in Australia either by air or sea from a polio-endemic or re-infected country. While the overall risk of an imported wild poliovirus infection leading to transmission within Australia is assessed as being low, some areas of the country have been identified as at increased risk. Local areas with relatively high arrivals from polio endemic countries, areas of low vaccination coverage and the potential for transmission to occur when these 2 factors are combined, were identified by this review as Australia's main polio risk. The risk of an importation event leading to locally acquired cases is mitigated by generally high polio vaccination coverage in Australia. This high coverage extends to residents of the Torres Strait Islands who are in close proximity to Papua New Guinea, a country identified as at high risk of poliovirus transmission should an importation occur. In 2012, all states and territories had vaccination coverage of greater than 90% at 1 year of age and all exceeded 93% at 2 years of age. Population immunity to wild poliovirus type 1, which remains the major cause of paralysis globally, has been estimated at 82%. This is sufficient to prevent outbreaks of this type in Australia. Of the 211 eligible non-polio acute flaccid paralysis (AFP) cases classified between 2008 and 2011, 91% (193) were vaccinated against polio at least once. High quality surveillance for AFP, which is supplemented by sentinel enterovirus and environmental surveillance activities, gives confidence that an imported case would be detected and appropriate public health action would ensue.

    Objective Despite public interest in the rural workforce, there are few published data on the geographical distribution of Australia's rural surgeons, their practice skill set, career stage or work-life balance (on-call burden). Similarly, there has not been a peer-reviewed skills audit of rural training opportunities for surgical trainees. The present study undertook this baseline assessment for Western Australia (WA), which has some of the most remote practice areas in Australia.Methods Hospital staff from all WA Country Health Service hospitals with surgical service (20 of 89 rural health services) were contacted by telephone. A total of 18 of 20 provided complete data. The study questionnaire explored hospital and practice locations of practicing rural surgeons, on-call rosters, career stage, practice skill set and the availability of surgical training positions. Data were tabulated in excel and geographic information system geocoded. Descriptive statistics were calculated in Excel.Results Of the seven health regions for rural Western Australia, two (28.6%) were served by resident surgeons at a ratio consistent with Royal Australasian College of Surgeons (RACS) guidelines. General surgery was offered in 16 (89%) hospitals. In total, 16 (89%) hospitals were served by fly-in, fly-out (FIFO) surgical services. Two hospitals with resident surgeons did not use FIFO services, but all hospitals without resident surgeons were served by FIFO surgical specialists. The majority of resident surgeons (62.5%) and FIFO surgeons (43.2%) were perceived to be mid-career by hospital staff members. Three hospitals (16.7%) offered all eight of the identified surgical skill sets, but 16 (89%) offered general surgery.Conclusions Relatively few resident rural surgeons are servicing large areas of WA, assisted by the widespread provision of FIFO surgical services. The present audit demonstrates strength in general surgical skills throughout regional WA, and augers well for the training

    An interest in mass spectrometry in Australia can be traced back to the 1920s with an early correspondence with Francis Aston who first visited these shores a decade earlier. The region has a rich tradition in both the development of the field and its application, from early measurements of ionization and appearance potentials by Jim Morrison at the Council for Scientific and Industrial Research (CSIR) around 1950 to the design and construction of instrumentation including the first use of a triple quadrupole mass spectrometer for tandem mass spectrometry, the first suite of programs to simulate ion optics (SIMION), the development of early TOF/TOF instruments and orthogonal acceleration and the local design and construction of several generations of a sensitive high-resolution ion microprobe (SHRIMP) instrument. Mass spectrometry has been exploited in the study and characterization of the constituents of this nation's unique flora and fauna from Australian apples, honey, tea plant and eucalyptus oil, snake, spider, fish and frog venoms, coal, oil, sediments and shale, environmental studies of groundwater to geochronological dating of limestone and granite, other terrestrial and meteoritic rocks and coral from the Great Barrier Reef. Peter Jeffery's establishment of geochronological dating techniques in Western Australia in the early 1950s led to the establishment of geochronology research both at the Australian National University and at what is now the Curtin Institute of Technology in the 1960s. This article traces the history of mass spectrometry in its many guises and applications in the island continent of Australia. An article such as this can never be complete. It instead focuses on contributions of scientists who played a major role in the early establishment of mass spectrometry in Australia. In general, those who are presently active in the field, and whose histories are incomplete, have been mentioned at best only briefly despite their important

    Along the western margin of the Australian continent there exist four major sedimentary basins, filled with predominantly marine rocks from Cambrian to Tertiary in age, and up to 40,000 feet thick. Seaward these basins continue into depressions recognizable in the continental shelf and even the continental slope. Their very presence, the nature of their sediments and the composition and relationships of their fossil faunas indicate the existence of an open ocean to the west of Australia since early Paleozoic time. Composition of the Australian fossil land vertebrate faunas suggests isolation of the Australian continent since at least Permian time. ?? 1959 Ferdinand Enke Verlag Stuttgart.

    Australia is comparable in size to the United States, but its population is far smaller, approximately 17 million. Australia is technologically advanced and has a high standard of health care, in which ET nursing has always been considered a specialist nursing role. Although Australia is historically linked with England, formation of closer ties with geographic neighbors, such as Southeast Asia, New Zealand, and the Pacific nations, is ongoing. This article describes some relevant aspects of the Australian context and considers the past, present, and expected future trends for ET nurse education in Australia, from the first program in 1971 to current World Council of Enterostomal Therapy-recognized programs teaching students from as far away as Japan, Israel, Singapore, Malaysia, New Zealand, China, Russia, and New Guinea. The content of the programs has progressively broadened in recognition of the expanded scope of practice, and this trend will undoubtedly continue. ET nursing should remain, however, a distinct nursing specialty practice in Australia.

    In all modelling studies of realistic scenarios, a researcher has to go through a number of steps to set up a model in order to produce a model simulation of value. The steps are generally the same, independent of the modelling system chosen. These steps include determining the time and space scales and processes of the required simulation; obtaining data for the initial set up and for input during the simulation time; obtaining observation data for validation or data assimilation; implementing scripts to run the simulation(s); and running utilities or custom-built software to extract results. These steps are time consuming and resource hungry, and have to be done every time irrespective of the simulation - the more complex the processes, the more effort is required to set up the simulation. The Australian Marine Virtual Laboratory (MARVL) is a new development in modelling frameworks for researchers in Australia. MARVL uses the TRIKE framework, a java-based control system developed by CSIRO that allows a non-specialist user configure and run a model, to automate many of the modelling preparation steps needed to bring the researcher faster to the stage of simulation and analysis. The tool is seen as enhancing the efficiency of researchers and marine managers, and is being considered as an educational aid in teaching. In MARVL we are developing a web-based open source application which provides a number of model choices and provides search and recovery of relevant observations, allowing researchers to: a) efficiently configure a range of different community ocean and wave models for any region, for any historical time period, with model specifications of their choice, through a user-friendly web application, b) access data sets to force a model and nest a model into, c) discover and assemble ocean observations from the Australian Ocean Data Network (AODN, http://portal.aodn.org.au/webportal/) in a format that is suitable for model evaluation or data assimilation, and

    Lake Mackay is the largest of hundreds of ephemeral lakes scattered throughout Western Australia and the Northern Territory, and is the second largest lake in Australia. The darker areas indicate some form of desert vegetation or algae, moisture within the soils, and lowest elevations where water pools. The image was acquired on September 19, 2010 and covers an area of 27 x 41 km. With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.

    The Great Barrier Reef extends for 2,000 kilometers along the northeastern coast of Australia. It is not a single reef, but a vast maze of reefs, passages, and coral cays (islands that are part of the reef). This nadir true-color image was acquired by the MISR instrument on August 26, 2000 (Terra orbit 3679), and shows part of the southern portion of the reef adjacent to the central Queensland coast. The width of the MISR swath is approximately 380 kilometers, with the reef clearly visible up to approximately 200 kilometers from the coast. It may be difficult to see the myriad details in the browse image, but if you retrieve the higher resolution version, a zoomed display reveals the spectacular structure of the many reefs.

    The more northerly coastal area in this image shows the vast extent of sugar cane cultivation, this being the largest sugar producing area in Australia, centered on the city of Mackay. Other industries in the area include coal, cattle, dairying, timber, grain, seafood, and fruit. The large island off the most northerly part of the coast visible in this image is Whitsunday Island, with smaller islands and reefs extending southeast, parallel to the coast. These include some of the better known resort islands such as Hayman, Lindeman, Hamilton, and Brampton Islands.

    Further south, just inland of the small semicircular bay near the right of the image, is Rockhampton, the largest city along the central Queensland coast, and the regional center for much of central Queensland. Rockhampton is just north of the Tropic of Capricorn. Its hinterland is a rich pastoral, agricultural, and mining region.

  5. An Update on SSA in Australia

    2011-09-01

    At AMOS 2008 the first author presented a review of surveillance of space activities in Australia up to that date: this paper reviews significant initiatives and events that have taken place since then. In summary some major policy commitments to Space Situational Awareness (SSA) have been made and some sizeable new R&D programs have been launched to develop nascent Australian SSA capabilities. Australia has still to settle on its national requirements for SSA and space generally, however, so these initiatives have yet to evolve into substantial, enduring programs of record. In more detail, the communiqués issued at the annual Australian-US ministerial consultations in November 2010 announced an in-principle commitment to Defence collaboration on SSA and to establishing a joint space tracking facility in Western Australia: Defence in Australia is now working through setting up this facility and how it will move into SSA generally. These are part of a larger national re-engagement with space: in particular in 2009 Australia committed to developing a national space policy and allocated A40 million of funding to a new Australian Space Research Program (ASRP) to boost space research. Over 5 million from this program has been awarded to projects centred on SSA, primarily to enhance EOS’ satellite laser tracking system. In addition to these projects, the partners in an allied Defence R&D agreement that includes DSTO have agreed to a joint experiment that will fly a small formation of suitably instrumented CubeSats with the aim of, inter alia, providing ground truth for testing SSA capabilities. More generally DSTO has been supporting various aspects of Defence’s engagement with SSA, including identification of S&T in which Australia has particular expertise that could be deployed on SSA given the necessary direction. The paper outlines these recent developments, reviews relevant Australian expertise in one particular field, tracking and sensor fusion (the second

    Northern Australia is biologically diverse and of national and global conservation signicance. Its ancient landscape contains the world's largest area of savannah ecosystem in good ecological condition and its rivers are largely free-flowing. Agriculture, previously confined largely to open range-land grazing, is set to expand in extent and to focus much more on irrigated cropping and horticulture. Demands on the water resources of the region are thus, inevitably increasing. Reliable information is required to guide and inform development and help plan for a sustainable future for the region which includes healthy rivers that contain diverse fish assemblages. Based on a range of information sources, including the outcomes of recent and extensive new field surveys, this study maps the distribution of the 111 freshwater fishes (excluding elasmobranches) and 42 estuarine vagrants recorded from freshwater habitats of the region. We classify the habitat use and migratory biology of each species. This study provides a comprehensive assessment of the diversity and distribution of fishes of the region within a standardised nomenclatural framework. In addition, we summarise the outcomes of recent phylogeographic and phylogenetic research using molecular technologies to identify where issues of taxonomy may need further scrutiny. The study provides an informed basis for further research on the spatial arrangement of biodiversity and its relationship to environmental factors (e.g. hydrology), conservation planning and phylogentic variation within individual taxa.

  7. The practice of clinical neuropsychology in Australia.

    2016-11-01

    This paper describes the development and practice of clinical neuropsychology in Australia. Clinical Neuropsychology has shown rapid growth in Australia over the past three decades. Comprehensive and specialized training programs are producing high quality graduates who are employed in a broad range of settings or private practice. Australia now has a substantial number of clinical neuropsychologists with specialist training. Whilst the majority of Australian clinical neuropsychologists still undertake assessment predominantly, there are growing opportunities for clinical neuropsychologists in rehabilitation and in a broad range of research contexts. Cultural issues relating to the assessment of Indigenous Australians and immigrants from many countries present significant challenges. Some major contributions have been made in the realms of test development and validation across various age groups. Australian clinical neuropsychologists are also contributing significantly to research in the fields of traumatic brain injury, aging and dementias, epilepsy, memory assessment, rehabilitation, substance abuse, and other psychiatric disorders. Expansion of roles of clinical neuropsychologists, in domains such as rehabilitation and research is seen as essential to underpin continuing growth of employment opportunities for the profession.

    Numerous algae reefs are seen in Shark Bay, Western Australia, Australia (26.0S, 113.5E) especially in the southern portions of the bay. The south end is more saline because tidal flow in and out of the bay is restricted by sediment deposited at the north and central end of the bay opposite the mouth of the Wooramel River. This extremely arid region produces little sediment runoff so that the waters are very clear, saline and rich in algae.

  10. Soil Carbon Sequestration: Perspectives from Australia

    NASA Astrophysics Data System (ADS)

    Sanderman, J.; Macdonald, L.; Baldock, J.

    2011-12-01

    Australia is currently embarking upon an unparalleled program to mitigate greenhouse gas emissions by engaging farmers and landholders to reduce emissions and store carbon in the soil. Currently, the magnitude of a potential soil carbon sink in Australian agricultural soils is largely unknown. The oft repeated rubric that adoption of recommended management practices (RMP) can raise soil carbon levels to 50-66% of pre-clearing levels has lead many to conclude that soil carbon sequestration can offset a large portion of Australia's current greenhouse gas emissions. Is there evidence in Australia (and abroad) to support these sequestration rates? In this presentation, we will present findings from both a retrospective analysis of existing field trial data and preliminary results from a national scale assessment of current soil carbon stocks under different agricultural management practices. A comprehensive review of field-trial data in Australia suggests that most management shifts within a given agricultural system (i.e. tillage, stubble management, fertilizer application, etc...) result in modest relative gains of 0.1 to 0.3 tC ha-1 yr-1. Importantly, whenever time series data was available, we found that the relative improvement in soil carbon stocks under RMPs was due to a reduction in the rate of loss of soil carbon and not in an actual increase in soil carbon. This finding has important repercussions for both how we think about soil carbon sequestration and how we can account for it in an accounting framework. Current research within the National Soil Carbon Research Program looks to assess the potential for agricultural management to influence soil carbon content and its distribution within various measurable carbon pools (particulate, humus, charcoal-like). For example, 200 randomly selected farms have been sampled in two major agricultural regions in South Australia based on a soil-type by rainfall stratification. In addition to measuring carbon content and

The focus is on Indian Settlers and Temporary Entrants admitted to Australia for employment and Indian students admitted to Australia for higher studies. The volume of emigration for permanent residence during the early 1990s has made India one of the leading source countries of migration to Australia. A majority of Indians admitted as Settlers every year join the labor force. Recent data indicate that, among Indian Settlers, there is a preponderance of unsponsored Independent Skilled Migrants. Given the anticipated growth in the number of Indian students, the coming years are likely to witness a spurt in Skilled Temporary Workers from India." excerpt

    Neutron scattering techniques have been part of the Australian scientific research community for the past three decades. The High Flux Australian Reactor (HIFAR) is a multi-use facility of modest performance that provides the only neutron source in the country suitable for neutron scattering. The limitations of HIFAR have been recognized and recently a Government initiated inquiry sought to evaluate the future needs of a neutron source. In essence, the inquiry suggested that a delay of several years would enable a number of key issues to be resolved, and therefore a more appropriate decision made. In the meantime, use of the present source is being optimized, and where necessary research is being undertaken at major overseas neutron facilities either on a formal or informal basis. Australia has, at present, a formal agreement with the Rutherford Appleton Laboratory (UK) for access to the spallation source ISIS. Various aspects of neutron scattering have been implemented on HIFAR, including investigations of the structure of biological relevant molecules. One aspect of these investigations will be presented. Preliminary results from a study of the interaction of the immunosuppressant drug, cyclosporin-A, with reconstituted membranes suggest that the hydrophobic drug interdigitated with lipid chains.

    Heron Island is located at the sourthern end of Australia's 2,050 km-long Great Barrier Reef. Surrounded by coral reef and home to over 1000 species of fish, scuba divers and scientists alike are drawn to the island's resort and research station. The true-color image above was taken by Space Imaging's Ikonos satellite with a resolution of 4 meters per pixel-high enough to see individual boats tied up at the small marina. The narrow channel leading from the marina to the ocean was blasted and dredged decades ago, before the island became a national park. Since then the Australian government has implemented conservation measures, such as limiting the number of tourists and removing or recycling, instead of incinerating, all trash. One of the applications of remote sensing data from Ikonos is environmental monitoring, including studies of coral reef health. For more information about the island, read Heron Island.

    This article proposes reconsideration of laws prohibiting paid surrogacy in Australia in light of increasing transnational commercial surrogacy. The social science evidence base concerning domestic surrogacy in developed economies demonstrates that payment alone cannot be used to differentiate "good" surrogacy arrangements from "bad" ones. Compensated domestic surrogacy and the introduction of professional intermediaries and mechanisms such as advertising are proposed as a feasible harm-minimisation approach. I contend that Australia can learn from commercial surrogacy practices elsewhere, without replicating them.

    2013-11-01

    Indigenous species of actinorhizal plants of Casuarinaceae, Elaeagnaceae and Rhamnaceae are found in specific regions of Australia. Most of these plants belong to Casuarinaceae, the dominant actinorhizal family in Australia. Many of them have significant environmental and economical value. The other two families with their indigenous actinorhizal plants have only a minor presence in Australia. Most Australian actinorhizal plants have their native range only in Australia, whereas two of these plants are also found indigenously elsewhere. The nitrogen-fixing ability of these plants varies between species. This ability needs to be investigated in some of these plants. Casuarinas form a distinctive but declining part of the Australian landscape. Their potential has rarely been applied in forestry in Australia despite their well-known uses, which are being judiciously exploited elsewhere. To remedy this oversight, a programme has been proposed for increasing and improving casuarinas that would aid in greening more regions of Australia, increasing the soil fertility and the area of wild life habitat (including endangered species). Whether these improved clones would be productive with local strains of Frankia or they need an external inoculum of Frankia should be determined and the influence of mycorrhizal fungi on these clones also should be investigated.

    The surface electric field induced by external geomagnetic source fields is modeled for a continental-scale 3-D electrical conductivity model of Australia at periods of a few minutes to a few hours. The amplitude and orientation of the induced electric field at periods of 360 s and 1800 s are presented and compared to those derived from a simplified ocean-continent (OC) electrical conductivity model. It is found that the induced electric field in the Australian region is distorted by the heterogeneous continental electrical conductivity structures and surrounding oceans. On the northern coastlines, the induced electric field is decreased relative to the simple OC model due to a reduced conductivity contrast between the seas and the enhanced conductivity structures inland. In central Australia, the induced electric field is less distorted with respect to the OC model as the location is remote from the oceans, but inland crustal high-conductivity anomalies are the major source of distortion of the induced electric field. In the west of the continent, the lower conductivity of the Western Australia Craton increases the conductivity contrast between the deeper oceans and land and significantly enhances the induced electric field. Generally, the induced electric field in southern Australia, south of latitude -20°, is higher compared to northern Australia. This paper provides a regional indicator of geomagnetic induction hazards across Australia.

    2009-12-01

    Geoscience Australia and the Australian State and Territory Geological Surveys have systematically surveyed most of the Australian continent over the past 40 years using airborne gamma-ray spectrometry to map potassium, uranium and thorium elemental concentrations at the Earth's surface. However, the individual surveys that comprise the national gamma-ray spectrometric radioelement database are not all registered to the same datum. This limits the usefulness of the database as it is not possible to easily combine surveys into regional compilations or make accurate comparisons between radiometric signatures in different survey areas. To solve these problems, Geoscience Australia has undertaken an Australia-Wide Airborne Geophysical Survey (AWAGS), funded under the Australian Government's Onshore Energy Security Program, to serve as a radioelement baseline for all current and future airborne gamma-ray spectrometric surveys in Australia. The AWAGS survey has been back-calibrated to the International Atomic Energy Agency's (IAEA) radioelement datum. We have used the AWAGS data to level the national radioelement database by estimating survey correction factors that, once applied, minimise both the differences in radioelement estimates between surveys (where these surveys overlap) and the differences between the surveys and the AWAGS traverses. The database is thus effectively levelled to the IAEA datum. The levelled database has been used to produce the first `Radiometric Map of Australia' - levelled and merged composite potassium (% K), uranium (ppm eU) and thorium (ppm eTh) grids over Australia at 100m resolution. Interpreters can use the map to reliably compare the radiometric signatures observed over different parts of Australia. This enables the assessment of key mineralogical and geochemical properties of bedrock and regolith materials from different geological provinces and regions with contrasting landscape histories.

  2. Late Cenozoic intraplate faulting in eastern Australia

    Babaahmadi, Abbas; Rosenbaum, Gideon

    2014-12-01

    The intensity and tectonic origin of late Cenozoic intraplate deformation in eastern Australia is relatively poorly understood. Here we show that Cenozoic volcanic rocks in southeast Queensland have been deformed by numerous faults. Using gridded aeromagnetic data and field observations, structural investigations were conducted on these faults. Results show that faults have mainly undergone strike-slip movement with a reverse component, displacing Cenozoic volcanic rocks ranging in ages from ˜31 to ˜21 Ma. These ages imply that faulting must have occurred after the late Oligocene. Late Cenozoic deformation has mostly occurred due to the reactivation of major faults, which were active during episodes of basin formation in the Jurassic-Early Cretaceous and later during the opening of the Tasman and Coral Seas from the Late Cretaceous to the early Eocene. The wrench reactivation of major faults in the late Cenozoic also gave rise to the occurrence of brittle subsidiary reverse strike-slip faults that affected Cenozoic volcanic rocks. Intraplate transpressional deformation possibly resulted from far-field stresses transmitted from the collisional zones at the northeast and southeast boundaries of the Australian plate during the late Oligocene-early Miocene and from the late Miocene to the Pliocene. These events have resulted in the hitherto unrecognized reactivation of faults in eastern Australia.

    The basal theropod dinosaur clade Ceratosauria, and its subclade Abelisauroidea, is characteristic of late Mesozoic terrestrial vertebrate faunas in western Gondwana (South America, Africa, Madagascar, and India) and Europe. Yet unambiguous records of ceratosaurs have hitherto been absent from Australia, where the theropod assemblage appears to include several typically Laurasian clades. Here, we report the first evidence of ceratosaurs (and potentially abelisauroids) from eastern Gondwana--a diagnostic astragalocalcaneum from the Aptian (121-125 Ma) of Victoria, Australia. Ceratosauria thus occurred in both western and eastern Gondwana during the Early Cretaceous. This fossil adds to the poorly known dinosaur fauna of Australia, a major clade of basal theropods, emphasising that its mid-Cretaceous theropod diversity was surprisingly cosmopolitan despite relative geographic isolation, including clades that have been thought to be typical of both Gondwana and Laurasia--Ceratosauria, Spinosauridae, Carcharodontosauria, Tyrannosauroidea, and Deinonychosauria. Such a contemporaneous association of theropod clades is unknown from other Gondwanan continents and questions the views that the late Mesozoic dinosaur fauna of Australia was dominated by Gondwanan or Laurasian elements, extreme isolation, relictualism, and/or novelty as a `centre of origin'. The cosmopolitan theropod fauna of Australia probably reflects the global distribution of these clades early in their history, prior to significant continental breakup.

  5. Oil and gas developments in Australia in 1984

    1985-10-01

    Exploration successes in Australia in 1984 were scored in the established hydrocarbon provinces: onshore, in the Eromanga-Cooper basins in South Australia and Queensland, and in the Surat basin and Denison trough in Queensland; offshore, in the Gippsland basin and along Australia's Northwest Shelf, in the Barrow and Dampier subbasins, and farther north, in the Vulcan subgraben. An encouraging feature of the Eromanga basin discoveries has been the progressive geographic spread of Mesozoic oil discoveries. There has been a stratigraphic spread also: in both South Australia and Queensland, oil is being found increasingly in Cretaceous reservoirs as well as in basal Jurassic reservoirs. Springton 1 was a Permian multizone gas discovery at the north end of the Denison trough. Further finds in intra-Latrobe sands were made in the Gippsland basin, notably Manta 1, near the 1983 Basker discovery. In the Dampier subbasin, a new-field discovery, Talisman 1, flowed 4,020 BOPD from an 11.5-m zone in the Barrow Group. Follow-up drilling at Jabiru in the Vulcan subgraben has been disappointing: 3 extension tests and 2 wildcats were plugged before the Challis 1 discovery. Canning basin exploration was essentially onshore in 1984 and yielded disappointments as well as some tantalizing encouragement. Pictor 1, on the Broome ridge, yielded the most promising flow of gas and oil yet achieved from low-productivity Ordovician carbonates. Results in the offshore Bonaparte, Arafura, and Carpentaria basins were discouraging, as were the widely spaced wildcats in the Drummond and Moreton basins in Queensland and the New South Wales portion of the Surat basin. Several onshore tests in the Carnarvon basin in Western Australia were unsuccessful. Very little drilling was attempted in South Australia beyond the confines of the Eromanga basin. Two tests each in the Otway and Bass basins of South Australia, Victoria, and Tasmania were unsuccessful.

    Because home hemodialysis has long been a common Australian support modality, the advent of home-based nocturnal hemodialysis (NHD) in Canada stimulated the extension of our existing home- and satellite-based conventional hemodialysis (CHD) programs to NHD. As a result, the first government-funded, home-based, 6-nights-per-week NHD program in Australia began in July 2001. Sixteen patients have been trained for NHD; 13 dialyzed at home 8 to 9 hr per night for 6 nights per week, whereas 3 preferred to train for NHD at home using an 8- to 9-hr alternate-night regime. The program experience to March 1, 2003, was 655 patient-weeks. Two patients had withdrawn for transplantation and 2 for social reasons, although 1 continues on alternate-night NHD. There hade been no deaths. Ten patients had dialyzed without partners. All patients ceased phosphate binders at entry. Thirteen of 16 discontinued all antihypertensive drugs. There were no fluid or dietary restrictions. Phosphate was added to the dialysate to prevent hypophosphatemia. Pre- and postdialysis urea and phosphate levels were broadly within the normal ranges. All patients reported restorative sleep; similarly partners reported stable sleep patterns and noted improved mood, cognitive function, and marital relationships in their NHD partners. Preliminary cost analyses show that whereas consumables had doubled, and epoetin and iron expenditures had risen by 28.9%, other pharmaceutical costs had fallen by 47%, and nursing wage costs were 48% of the notional cost had these patients remained on CHD. Three patients on NHD were retired, 7 worked full-time, 3 worked part-time, and 3 drew disability support, whereas previously on CHD, 3 were retired, 3 had worked full-time, 3 had worked part-time, and 7 had drawn disability support. We believe that NHD is viable, safe, effective, and well accepted with significant lifestyle benefits and reemployment outcomes. Although initial setup costs are significant, NHD cost advantage

    Hamelin Pool Marine Nature Reserve is located in the Shark Bay World Heritage Site in Western Australia. It is one of the very few places in the world where living stromatolites can be found. These are the first living examples of structures built by cyanobacteria. These bacteria are direct descendants of the oldest form of photosynthetic life on earth, dating back 3,500 million years (Wikipedia). The image was acquired December 30, 2010, covers an area of 34 x 46 km, and is located at 26.4 degrees south latitude, 114.1 degrees east longitude. With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.

    Situated in the Timor Sea and Joseph Bonaparte Gulf regions, the Bonaparte basin is one of the Phanerozoic basins of what is now called the North West Shelf of Australia. This basin consists of a number of Paleozoic and Mesozoic synclines and horsts. Drilling success rate for this basin is one of the highest in Australia in the last 5 years. New opportunities are available in the southeastern Bonaparte basin, where seven vacant tracts have just been released for application for exploration permits. The paper discusses the regional geology, previous exploration activities, and potentials of the southern Petrel sub-basin and Darwin shelf.

    1990-12-10

    STS035-81-040 (2-10 Dec 1990) --- Numerous algae reefs are seen in Shark Bay, Western Australia, Australia (26.0S, 113.5E) especially in the southern portions of the bay. The south end is more saline because tidal flow in and out of the bay is restricted by sediment deposited at the north and central end of the bay opposite the mouth of the Wooramel River. This extremely arid region produces little sediment runoff so that the waters are very clear, saline and rich in algae.

  10. The mismatch of bioaccumulated trace metals (Cu, Pb and Zn) in field and transplanted oysters (Saccostrea glomerata) to ambient surficial sediments and suspended particulate matter in a highly urbanised estuary (Sydney estuary, Australia).

    2016-04-01

    A significant correlation between sedimentary metals, particularly the 'bio-available' fraction, and bioaccumulated metal concentrations in the native Sydney rock oyster (Saccostrea glomerata) tissues has been successfully demonstrated previously for Cu and Zn in a number of estuaries in New South Wales, Australia. However, this relationship has been difficult to establish in a highly modified estuary (Sydney estuary, Australia) where metal contamination is of greatest concern and where a significant relationship would be most useful for environmental monitoring. The use of the Sydney rock oyster as a biomonitoring tool for metal contamination was assessed in the present study by investigating relationships between metals attached to sediments and suspended particulate matter (SPM) to bioaccumulated concentrations in oyster tissues. Surficial sediments (both total and fine-fraction), SPM and wild oysters were collected over 3 years from three embayments (Chowder Bay, Mosman Bay and Iron Cove) with each embayment representing a different physiographic region of Sydney estuary. In addition, a transplant experiment of farmed oysters was conducted in the same embayments for 3 months. No relationship was observed between sediments or SPM metals (Cu, Pb and Zn) to tissue of wild oysters; however, significant relationship was observed against transplanted oysters. The mismatch between wild and farmed, transplanted oysters is perplexing and indicates that wild oysters are unsuitable to be used as a biomonitoring tool due to the involvement of unknown complex factors while transplanted oysters hold strong potential.

  8. Review of Australia's polio surveillance.

    2013-06-30

    With eradication almost within reach, the importance of detecting every poliomyelitis case has taken on additional significance. The selected surveillance strategy must be effective and efficient. A review of polio surveillance in Australia was conducted to consider whether current strategies were optimal. Document review and semi-structured key informant interviews were used to conduct the review. Interviews were recorded, transcribed and thematically analysed. The review was an iterative process with feedback on the findings sought from interviewees. Since Western Pacific Regional polio-elimination status was certified, one imported adult case was detected in 2007 in Australia, with no evidence of further transmission, and no Australian paediatric cases identified. Respondents reported that: it was not possible to prevent importations; paediatric cases were more likely to be identified than adult cases; and there may be a low level of suspicion among clinicians. Case detection and outbreak mitigation were considered key reasons to undertake polio surveillance. While Australia has not achieved one of the key World Health Organization (WHO) surveillance targets, this did not compromise Australias polio-free status. Identified issues with polio surveillance were the potential for an importation with high attendant investigation and containment costs, low stool sample collection rates, and the opportunity to improve safeguards around the importation and laboratory storage of biological samples containing poliovirus. The review found strong support for ongoing polio surveillance, particularly to detect imported cases and to demonstrate commitment to maintaining a polio-free region. Existing polio surveillance strategies were considered appropriate for Australia. This work is copyright.

  9. The crustal thickness of Australia

    2000-01-01

    We investigate the crustal structure of the Australian continent using the temporary broadband stations of the Skippy and Kimba projects and permanent broadband stations. We isolate near-receiver information, in the form of crustal P-to-S conversions, using the receiver function technique. Stacked receiver functions are inverted for S velocity structure using a Genetic Algorithm approach to Receiver Function Inversion (GARFI). From the resulting velocity models we are able to determine the Moho depth and to classify the width of the crust-mantle transition for 65 broadband stations. Using these results and 51 independent estimates of crustal thickness from refraction and reflection profiles, we present a new, improved, map of Moho depth for the Australian continent. The thinnest crust (25 km) occurs in the Archean Yilgarn Craton in Western Australia; the thickest crust (61 km) occurs in Proterozoic central Australia. The average crustal thickness is 38.8 km (standard deviation 6.2 km). Interpolation error estimates are made using kriging and fall into the range 2.5-7.0 km. We find generally good agreement between the depth to the seismologically defined Moho and xenolith-derived estimates of crustal thickness beneath northeastern Australia. However, beneath the Lachlan Fold Belt the estimates are not in agreement, and it is possible that the two techniques are mapping differing parts of a broad Moho transition zone. The Archean cratons of Western Australia appear to have remained largely stable since cratonization, reflected in only slight variation of Moho depth. The largely Proterozoic center of Australia shows relatively thicker crust overall as well as major Moho offsets. We see evidence of the margin of the contact between the Precambrian craton and the Tasman Orogen, referred to as the Tasman Line. Copyright 2000 by the American Geophysical Union.

    2016-12-01

    Solar-terrestrial physics research in Australia began in 1792 when de Rossel measured the southern hemisphere geomagnetic field at Recherche Bay on the southern tip of Tasmania, proving the field magnitude and direction varied with latitude. This was the time when the French and British were competing to chart and explore the new world. From the early twentieth century Australian solar-terrestrial physics research concentrated on radio wave propagation and communication, which by the 1950s fed into the International Geophysical Year in the areas of atmosphere and ionosphere physics, and geomagnetism, with some concentration on Antarctic research. This was also the era of increased studies of solar activity and the discovery of the magnetosphere and the beginning of the space age. In the 1960s, Australia became a world leader in solar physics which led to radio astronomy discoveries. This paper outlines the historical development of solar-terrestrial physics in Australia and its international connections over the years and concludes with examples of specific research areas where Australia has excelled.

    The Gippsland Basin Province 3930, located on the southeastern coast of Australia, is formed from two successive failed rifts that developed into a passive margin during the Cretaceous. Formation of this basin is related to the break up of Gondwana, which resulted in the separation of Antarctica from Australia, and the separation of the New Zealand and Lord Howe Rise continental crust from Australia. Coals and coaly shales of Late Cretaceous through Eocene age are the source rocks for oil and gas that accumulated predominantly in anticlinal traps. The basin was Australia?s major producing basin until 1996 when daily oil/condensate production from the North West Shelf surpassed it.

  12. Surveillance of Space in Australia

    NASA Astrophysics Data System (ADS)

    Newsam, G.

    Australia's geography and technology base got it off to a flying start in the early days of surveillance of space, starting with CSIRO's first radio telescope in the 1940's and climaxing in NASA's establishment of station 43 in the Deep Space Network at Tidbinbilla in 1965. But Britain's exit from space and the subsequent closure of the Woomera launch range and associated space tracking facilities in the early 1970's saw the start of a long draw-down of capability. Programs such as CSIRO's radio astronomy telescopes, Electro-Optic Systems' adoption of laser technology for satellite laser ranging and tracking system, and the exploration of the use of technology developed in Australia's over-the-horizon-radar program for surveillance of space, kept some interest in the problem alive, but there has been no serious national investment in the area for the last thirty years. Recently, however, increased awareness of the vulnerability of space systems and the need to include potential opponents' space capabilities in operations planning has led to a revival of interest in space situational awareness within the Australian Defence Organisation. While firm commitments to new systems must wait on the next Defence White Paper due out at the end of 2007 and the policy directions it formally endorses, discussions have already started with the US on participating in the Space Surveillance Network (SSN) and developing a comprehensive space situational awareness capability. In support of these initiatives the Defence Science and Technology Organisation (DSTO) is drawing up an inventory of relevant Australian capabilities, technologies and activities: the paper will describe the findings of this inventory, and in particular local technologies and systems that might be deployed in Australia to contribute to the SSN. In the optical regime the available options are rather limited; they centre primarily on the satellite laser ranging technology developed by Electro-Optic Systems and

    1999-12-01

    A cluster of acute melioidosis cases occurred in a remote, coastal community in tropical Western Australia. Molecular typing of Burkholderia pseudomallei isolates from culture-confirmed cases and suspected environmental sources by pulsed-field gel electrophoresis (PFGE) of XbaI chromosomal DNA digests showed that a single PFGE type was responsible for five cases of acute infection in a community of around 300 during a 5 week period. This temporal and geographical clustering of acute melioidosis cases provided a unique opportunity to investigate the environmental factors contributing to this disease. B. pseudomallei isolated from a domestic tap at the home of an asymptomatic seroconverter was indistinguishable by PFGE. Possible contributing environmental factors included an unusually acid communal water supply, unrecordable chlorine levels during the probable exposure period, a nearby earth tremor, and gusting winds during the installation of new water and electricity supplies. The possible role of the potable water supply as a source of B. pseudomallei was investigated further.

    PubMed

    March, Lynette M; Bagga, Hanish

    2004-03-01

    Arthritis affects around 3 million people in Australia, representing about 15% of the population. Osteoarthritis is the leading cause of pain and disability among the elderly. Osteoarthritis is the third leading cause of life-years lost due to disability. Obesity and joint injury are important potentially modifiable risk factors for the development of osteoarthritis. Obesity is also an important predictor of progression of osteoarthritis. Currently, about 19000 hip and 20000 knee replacements are performed for osteoarthritis in Australia each year. Prevalence of osteoarthritis and the need for total joint replacement surgery are likely to increase because of a combination of increasing risk factors (age, obesity, injury), increasing expectations for improved quality of life, and improved surgical and anaesthetic techniques making surgery possible for more people. Services to provide these cost-effective procedures need to be increased. Primary and secondary prevention programs aimed at reducing obesity, preventing injury and improving rehabilitation and physical activity are urgently required.

    We reviewed anaesthesia training program in Australia. Anaesthetists in Australia and New Zealand need to obtain the Diploma of Fellowship of the Australian and New Zealand College of Anaesthetists (FANZCA) to be recognised as specialists. The training sequence approved by ANZCA encompasses an initial two-year Prevocational Medical Education, Training (PMET) period, and the five-year period of ANZCA Approved Training, which included two-year Basic Training and three-year Advanced Training. On completion of all Training Program requirements the Trainee is awarded the Diploma of Fellowship and is entitled to use the qualification of FANZCA. The assessment of trainees in anaesthesia is principally by examination and the staff of the hospitals in which trainees work. There are a number of specific goals to be achieved during training. ANZCA accredits Hospital Departments of Anaesthesia and other training institutions across Australia, New Zealand, and South-East Asia, to provide approved training in anaesthesia for ANZCA trainees. Accreditation requires an onsite review by the College in order to assess a hospital's ability to provide training and supervision of the required standard, and its degree of compliance with ANZCA Professional Documents.

  4. Deliberate introduction of the European rabbit, Oryctolagus cuniculus, into Australia.

    PubMed

    Fenner, F

    2010-04-01

    The European rabbit was brought to Australia as a companion animal by early settlers. It sometimes escaped, but failed to survive in the Australian bush. In 1879 wild rabbits were deliberately sent to Victoria to provide game for wealthy settlers to shoot. They soon spread all over Australia, except in the tropics, and became Australia's major animal pest. After careful testing in Australian wildlife and in humans, control by myxoma virus was introduced at various sites between 1937 and 1950, spreading all over the Murray-Darling Basin in 1950. Within one year mutations in the virus had led to slightly less virulence, and these continued for the next 50 years. In the early 21st Century testing viruses obtained from wild rabbits showed that the majority of these viruses were more virulent than the virus used to initiate the epidemic. In 1995 another virus specific for European rabbits, rabbit haemorrhagic disease virus, escaped from areas in which field trials were being carried out and spread around Australia. It was more successful than myxomatosis for rabbit control in arid regions.

    The National Notifiable Diseases Surveillance System received 1,385 tuberculosis (TB) notifications in 2011, representing a rate of 6.2 cases per 100,000 population. While Australia has maintained a rate of 5 to 6 cases per 100,000 for TB since the mid-1980s, there has been a steady increase in incidence over the past decade. In 2011, Australia's overseas-born population continued to represent the majority of TB notifications (88%) with a notification rate of 20.2 per 100,000. The incidence of TB in the Australian-born Indigenous population has fluctuated over the last decade and showed no clear trend; however, in 2011 the notification rate was 4.9 per 100,000, which is a notable decrease from the 7.5 per 100,000 recorded in 2010. The incidence of TB in the Australian-born non-Indigenous population has continued to remain low at 0.9 per 100,000. Australia continued to record only a small number of multi-drug-resistant TB (MDR-TB) cases nationally (n=25), all of which were identified in the overseas-born population. To ensure that Australia can retain its low TB rate and work toward reducing rates further, it is essential that Australia maintains good centralised national TB reporting to monitor trends and identify at-risk populations, and continues to contribute to global TB control initiatives.

  6. Biotech prospects for the control of introduced mammals in Australia.

    More than twenty exotic vertebrate species are now listed as pests in Australia. Collectively, these pests have a huge economic and environmental impact and pose a major threat to Australia's ecosystems and unique biodiversity. Management of such pests on a continental scale is a major challenge. Recent advances in biotechnology suggest alternatives to the lethal diseases normally sought for use as biological control agents. One proposal, being investigated in the Pest Animal Control Cooperative Research Centre, Canberra, is the use of biotechnology to develop a new generation of agents that act through controlling reproduction to prevent the build up of pest populations. The core concept is fertility control through immunocontraceptive vaccines delivered by viruses that specifically infect the target pest population. Proof of this exciting concept has been obtained for the mouse and, very recently, the rabbit, and a candidate vaccine vector identified for the fox, portending better control of a trio of Australia's most pervasive pests. Other advances in biotechnology suggest ways to negate the build up of both innate and acquired immune resistance in target pest populations that normally act to limit the efficacy and effective life of biocontrol agents in the field. Prospects for extending the use of virally vectored vaccines to the field management of wildlife diseases are also identified. Targets for such vaccines include a growing suite of emerging diseases, hosted by Australia's wildlife, which pose a threat to human and livestock health. Numerous technical challenges remain to be addressed before any of these new agents are ready for use in the field. However, the major risk to their development is now no longer viewed as being technical, but the failure to gain public acceptance for their use in the field. This already significant risk is exasperated by the present heightened level of public concern about all introductions of genetically modified organisms.

    There is ample contempory evidence that most meteorological themometers in Australia were not exposed in Stevenson screens until very late in the nineteenth century, and in many places not until well into the twentieth century. There is also evidence, from a long-running comparision at Adelaide, that mean temperatures in a Stevenson screen are lower than in an open stand in Australian conditions. Thus, there are strong grounds for expecting that ninteenth century, and some early twentieth century, Australian temperatures are biased warm, relative to modern exposures.

    Land cover information is critical for national reporting and decision making in Australia. A review of information requirements for reporting on national environmental indicators identified the need for consistent land cover information to be compared against a baseline. A Dynamic Land Cover Dataset (DLCD) for Australia has been developed by Geoscience Australia and the Australian Bureau of Agriculture and Resource Economics and Sciences (ABARES) recently, to provide a comprehensive and consistent land cover information baseline to enable monitoring and reporting for sustainable farming practices, water resource management, soil erosion, and forests at national and regional scales. The DLCD was produced from the analysis of Enhanced Vegetation Index (EVI) data at 250-metre resolution derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) for the period from 2000 to 2008. The EVI time series data for each pixel was modelled as 12 coefficients based on the statistical, phenological and seasonal characteristics. The time series were then clustered in coefficients spaces and labelled using ancillary information on vegetation and land use at the catchment scale. The accuracy of the DLCD was assessed using field survey data over 25,000 locations provided by vegetation and land management agencies in State and Territory jurisdictions, and by ABARES. The DLCD is seen as the first in a series of steps to build a framework for national land cover monitoring in Australia. A robust methodology to provide annual updates to the DLCD is currently being developed at Geoscience Australia. There is also a growing demand from the user community for land cover information at better spatial resolution than currently available through the DLCD. Global land cover mapping initiatives that rely on Earth observation data offer many opportunities for national and international programs to work in concert and deliver better outcomes by streamlining efforts on development and

    Abstract This article adopts a human rights lens to consider Australian law and practice regarding elective abortion. As such, it considers Australian laws within the context of the right to equality, right to privacy, right to health, and right to life. After setting out the human rights framework and noting the connected nature of many of the rights (and their corresponding violations), the article shifts its focus to analyzing Australian law and practice within the framework of these rights. It considers the importance of decriminalizing abortion and regulating it as a standard medical procedure. It discusses the need to remove legal and practical restrictions on access to abortion, including financial obstacles and anti-abortion protestors. Further, it comments on the importance of facilitating access; for example, by keeping accurate health data, securing continuity of health care, increasing the availability of medical abortion, and ensuring appropriate care is provided to the most marginalized and vulnerable women.

  18. Rural male suicide in Australia.

    PubMed

    Alston, Margaret

    2012-02-01

    The rate of suicide amongst Australia's rural men is significantly higher than rural women, urban men or urban women. There are many explanations for this phenomenon including higher levels of social isolation, lower socio-economic circumstances and ready access to firearms. Another factor is the challenge of climate transformation for farmers. In recent times rural areas of Australia have been subject to intense climate change events including a significant drought that has lingered on for over a decade. Climate variability together with lower socio-economic conditions and reduced farm production has combined to produce insidious impacts on the health of rural men. This paper draws on research conducted over several years with rural men working on farms to argue that attention to the health and well-being of rural men requires an understanding not only of these factors but also of the cultural context, inequitable gender relations and a dominant form of masculine hegemony that lauds stoicism in the face of adversity. A failure to address these factors will limit the success of health and welfare programs for rural men. Copyright © 2010 Elsevier Ltd. All rights reserved.

  19. Tuberculosis notifications in Australia, 2010.

    The National Notifiable Diseases Surveillance System received 1,353 tuberculosis (TB) notifications in 2010, representing a rate of 6.1 cases per 100,000 population. While rates of 5 to 6 cases per 100,000 population for TB have been maintained in Australia, since first achieved in the mid-1980s, there has been a steady increase in incidence over the past decade. The incidence in the Australian-born Indigenous population was 7.5 per 100,000 population, which is 11 times the incidence reported in the Australian-born non-Indigenous population of 0.7 per 100,000 population. Overseas-born people accounted for 90% of all cases notified in 2010 and represented a rate of 24 per 100,000 population. International students have been recognised as an increasingly important group, representing 25% of all overseas-born cases notified in 2010, and are a focus of this report. Household or other close contact with TB or past residence in a high risk country were the most commonly reported risk factors for TB infection. Outcome data for the 2009 TB cohort indicate that treatment success was attained in more than 95% of cases. As Australia continues to contribute to global TB control it is important to maintain good centralised national reporting of TB to identify populations at risk and monitor trends in TB. copyright@health.gov.au

  20. An Impact Crater in Palm Valley, Central Australia?

    2011-05-01

    We explore the origin of a 280 m wide, heavily eroded circular depression in Palm Valley, Northern Territory, Australia using gravity, morphological, and mineralogical data collected from a field survey in September 2009. From the analysis of the survey, we debate probable formation processes, namely erosion and impact, as no evidence of volcanism is found in the region or reported in the literature. We argue that the depression was not formed by erosion and consider an impact origin, although we acknowledge that diagnostics required to identify it as such (e.g. meteorite fragments, shatter cones, shocked quartz) are lacking, leaving the formation process uncertain. We encourage further discussion of the depression's origin and stress a need to develop recognition criteria that can help identify small, ancient impact craters. We also encourage systematic searches for impact craters in Central Australia as it is probable that many more remain to be discovered.

    Forensic entomology as a science and a tool for investigation has had slow beginnings in Australia. A number of small animal decomposition trials have been recorded in the literature but mostly from an ecological rather than a forensic entomology perspective. In the last 20 years, a number of more forensically orientated field trials on small pigs and some fly developmental trials in the laboratory have been conducted but lack any replication. The following article was presented at an international seminar to detail the current research in forensic entomology, the applications of forensic entomology in scene of crime (SOC) and homicide investigations and the education of police and judiciary in the discipline of forensic entomology in Western Australia over the last 10 years.

    Ig levels were determined by radial immunodiffusion in uncomplicated cases of acute hepatitis with or without Australia antigenaemia. Initial sera from Australia antigen negative cases showed a striking elevation in IgM levels when compared to Australia antigen positive cases (6·5 versus 1·9 mg/ml). None of twenty-four Australia antigen positive cases exceeded 3 mg/ml IgM, and only 3/58 Australia antigen negative cases exhibited values below 3 mg/ml. Intial sera from Australia antigen positive and Australia antigen negative subjects did not differ in concentration of IgG, IgA, or IgD. Serial determinations of IgG revealed a transient fall in patients with Australia antigen positive hepatitis, and a rise in Australia antigen negative cases. Asymptomatic, Australia antigen positive, Guaymi Indian subjects were compared to matched Australia antigen negative controls from the same indigenous group and no differences in the concentration of IgG, IgM, IgA or IgD were found, although elevations of IgG and IgM were common in both groups. No evidence of abnormal proteins was found when sera were tested by cellulose acetate electrophoresis or by immunoelectrophoresis versus immunoglobulin-specific antisera. Ultracentrifugal analysis failed to detect `7S' IgM. PMID:4625396

    We estimated the relationship between religion and body mass index (BMI) for a general and representative sample of the Australia population. Data from the Household Income Labour Dynamics survey were analysed for 9,408 adults aged 18 and older. OLS regression analyses revealed that religious denomination was significantly related to higher BMI, after controlling for socio-demographic, health behaviours, and psychosocial variables. 'Baptist' men had, on average, a 1.3 higher BMI compared to those reporting no religious affiliation. Among women, 'Non-Christians' had, on average, a 1 unit lower BMI compared to those reporting no religious affiliation while 'Other Christian' women reported, on average, a 1 unit higher BMI. Our results also indicate that there was a negative relationship between religious importance and BMI among Australian women.

    2011-02-21

    In recent years, a phenomenon of "late effects of the Holocaust" has emerged, with impacts on the psychological and physical health of ageing Holocaust survivors. As Holocaust survivors age, they may experience heightened anxiety around normal processes of ageing, worsened post-traumatic stress disorder with cognitive decline, and fear of the medical system. Holocaust survivors are at increased risk of osteoporosis, cardiometabolic disease due to hypothalamic-pituitary-adrenal axis dysfunction, cancer, and sequelae of Nazi medical experiments. From existing medical literature on this topic, practical principles of management are derived to create a framework for sensitive medical management of Holocaust survivors in Australia. The issues discussed are also relevant to the wider geriatric refugee or prisoner-of-war experience.

  16. Skin cancer prevention in Australia.

    PubMed

    Sinclair, C; Foley, P

    2009-11-01

    Australia has one of the highest skin cancer incidence and mortality rates in the world. The reason for these high rates is due in part to the high ambient UV radiation levels, combined with a predominantly susceptible fair-skinned population. To address this problem, since 1980 Australians have been exposed to social marketing campaigns to raise awareness of skin cancer prevention. These campaigns have used mass media alongside interventions in schools, workplaces, and in community and leisure settings to motivate sun protective behaviour. As a result of these interventions it can be demonstrated that social marketing campaigns can be a very effective method to not only motivate behaviour change, reduce sunburn, and increase awareness but more importantly, reduce melanoma rates and bring positive economic returns to government. However long term investment in this area is required otherwise any population gains in behaviour are very likely to be quickly eroded.

    2006-09-01

    I recently watched a fascinating documentary about the crusade of Dr Bertram Wainer in the 1960s to bring the practice of illegal abortion in Victoria to an end. It documented the profound horror of the backyard abortion that so often ended in infection, sterility or death, and served as a potent reminder of a practice to which we must never return. Of course that cant happen again, abortion is legal now, isnt it? In Victoria in 1969 a Supreme Court judge ruled that an abortion is not unlawful if a doctor believed that: the abortion is necessary to preserve the woman from serious danger to her life or physical or mental health (Menhennit ruling). In Australia today however, abortion law remains conditional, unclear and inconsistent and, except in the ACT, is still part of criminal statutes.

    In Australia, the strengthening of marriage through relationship education has received strong governmental policy support and some modest financial support. Couple relationship education services are offered by a variety of community-based, church-affiliated, and church-based providers. There is a strong emphasis on providing programs that are developed locally in response to perceived couple needs and government policies. Available evaluations show that most couples who attend education value the service, but relationship education providers need to do a better job reaching out to couples at high risk for future relationship problems, and more research is needed on the effects of education on long-term marital outcomes. There is significant scope for building on current initiatives to incorporate evidence-based approaches and to expand the program reach to more couples.

    NASA Image and Video Library

    2017-09-27

    In late July 2013, a low pressure system off Australia’s southeast coast and moist onshore winds combined to create unsettled weather across central Australia – and a striking image of a broad cloud band across the stark winter landscape. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image on July 22 at 01:05 UTC (10:35 a.m. Australian Central Standard Time). To the west of the low pressure trough the skies are clear and dry. To the east, the broad band of bright white clouds obscures the landscape. The system brought wind, precipitation and cooler temperatures to the region. The same day as MODIS captured this image, the Naval Research Lab (NRL) published an edition of the Global Storm Tracker (GST), which gave a world-wide view of the low-pressure systems across the world. This tracker shows the entire cloud band across Australia, as well as the location of the low pressure system.

  1. Understanding extreme rainfall events in Australia through historical data

    NASA Astrophysics Data System (ADS)

    Ashcroft, Linden; Karoly, David John

    2016-04-01

    Historical climate data recovery is still an emerging field in the Australian region. The majority of Australia's instrumental climate analyses begin in 1900 for rainfall and 1910 for temperature, particularly those focussed on extreme event analysis. This data sparsity for the past in turn limits our understanding of long-term climate variability, constraining efforts to predict the impact of future climate change. To address this need for improved historical data in Australia, a new network of recovered climate observations has recently been developed, centred on the highly populated southeastern Australian region (Ashcroft et al., 2014a, 2014b). The dataset includes observations from more than 39 published and unpublished sources and extends from British settlement in 1788 to the formation of the Australian Bureau of Meteorology in 1908. Many of these historical sources provide daily temperature and rainfall information, providing an opportunity to improve understanding of the multidecadal variability of Australia's extreme events. In this study we combine the historical data for three major Australian cities - Melbourne, Sydney and Adelaide - with modern observations to examine extreme rainfall variability over the past 174 years (1839-2013). We first explore two case studies, combining instrumental and documentary evidence to support the occurrence of severe storms in Sydney in 1841 and 1844. These events appear to be at least as extreme as Sydney's modern 24-hour rainfall record. Next we use a suite of rainfall indices to assess the long-term variability of rainfall in southeastern Australia. In particular, we focus on the stationarity of the teleconnection between the El Niño-Southern Oscillation (ENSO) phenomenon and extreme rainfall events. Using ENSO reconstructions derived from both palaeoclimatic and documentary sources, we determine the historical relationship between extreme rainfall in southeastern Australia and ENSO, and examine whether or not this

Australia's Terrestrial Ecosystem Research Network (TERN) is a national research infrastructure investment designed to support the ecosystem science community through all stages of the data lifecycle. TERN has developed and implemented a comprehensive network of ';hard' and ';soft' infrastructure that enables Australia's ecosystem scientists to collect, publish, store, share, discover and re-use data in ways not previously possible. The aim of this poster is to demonstrate how TERN has successfully delivered infrastructure that is enabling a significant cultural and practical shift in Australia's ecosystem science community towards consistent approaches for data collection, meta-data, data licensing, and data publishing. TERN enables multiple disciplines, within the ecosystem sciences to more effectively and efficiently collect, store and publish their data. A critical part of TERN's approach has been to build on existing data collection activities, networks and skilled people to enable further coordination and collaboration to build each data collection facility and coordinate data publishing. Data collection in TERN is through discipline based facilities, covering long term collection of: (1) systematic plot based measurements of vegetation structure, composition and faunal biodiversity; (2) instrumented towers making systematic measurements of solar, water and gas fluxes; and (3) satellite and airborne maps of biophysical properties of vegetation, soils and the atmosphere. Several other facilities collect and integrate environmental data to produce national products for fauna and vegetation surveys, soils and coastal data, as well as integrated or synthesised products for modelling applications. Data management, publishing and sharing in TERN are implemented through a tailored data

    Severe thunderstorms are a common occurrence in Australia and have been documented since the first European settlement in 1788. These events are characterized by large damaging hail in excess of 2 cm, convective wind gusts greater than 90 km h- 1 and tornadoes, and contribute a quarter of all natural hazard-related losses in the country. This impact has lead to a growing body of research and insight into these events. In this article, the state of knowledge regarding their incidence, distribution, and the resulting hail, tornado, convective wind, and lightning risk will be reviewed. Applying this assessment of knowledge, the implications for forecasting, the warning process, and how these events may respond to climate change and variability will also be discussed. Based on this review, ongoing work in the field is outlined, and several potential avenues for future research and exploration are suggested. Most notably, the need for improved observational or proxy climatologies, the forecasting guidelines for tornadoes, and the need for a greater understanding of how severe thunderstorms respond to climate variability are highlighted.

  4. Petroleum prospectivity in Precambrian and Early Paleozoic basins, Australia

    Proterozoic to Devonian age strata with some potential for petroleum accumulations are known from sedimentary basins covering {approximately}1,870,000 km{sup 2} onshore Australia. Portions of these very old basins have not sustained the deleterious effects of deep burial. Explorers with vision continue to target these very old rocks in the MacArthur/South Nicholson, Amadeus, Canning, Adavale, and Bonaparte basins. Approximately 429,000 km{sup 2} of these basins remain under license for petroleum exploration. The oldest known oil in Australia is reservoired within and sourced from the mid-Proterozoic in the McArthur basin. The Early Ordovician Pacoota Sandstone of the Amadeus basin is the oldest formation commercially exploited for oil and gas in Australia. Significant discoveries awaiting development include Dingo, Pictor, and Gilmore. The Tern gas field trap in the Bonaparte basin is related to a salt diapir; the salt probably being Silurian-Devonian in age. Salt probably of the same age has formed diapirs in the Canning basin, too. Cambrian and Proterozoic salt-bearing strata are likewise the cause and core of some anticlinal and diapiric structures in the Amadeus basin. Minor oil shows have been reported from the Cambrian of the Officer basin. The Warburton, Pedirka, Arrowie, Ord, Wiso, Georgina, and Ngalia basins contain Proterozoic and early Paleozoic sedimentary rocks but are ascribed only limited petroleum prospectivity at this time.

    Eastern Australia is covered by a series of continental sedimentary basins deposited during the Triassic and Jurassic, but the geodynamic context of these basins is not fully understood. Using gridded aeromagnetic data, seismic reflection data, geological maps, digital elevation models, and field observations, we conducted a structural synthesis aimed at characterizing major structures and deformation style in the Triassic-Jurassic sedimentary basins of eastern Australia. Our results show evidence for four alternating episodes of rifting and contractional events during the Triassic. Two major episodes of rifting, characterized by syn-sedimentary steep normal faults and bimodal volcanism, resulted in the development of the Early-Middle Triassic Esk-Nymboida Rift System and the early Late Triassic Ipswich Basin. Faults in the Esk-Nymboida Rift System have been controlled by a pre-existing oroclinal structure. Each phase of rifting was followed by a contractional event, which produced folds, reverse faults and unconformities in the basins. Since the latest Late Triassic, thermal subsidence led to the deposition of continental sediments in the Clarence-Moreton Basin, which continued until the Early Cretaceous. We suggest that the geodynamic control on the alternating episodes of rifting and contraction during the Triassic in eastern Australia was ultimately related to plate boundary migration and switches between trench retreat and advance.

    Paramedic education has been undergoing major development in Australia in the past 20 years, with many different educational programmes being developed across all Australian jurisdictions. This paper aims to review the current paramedic education programmes in Australia to identify the similarities and differences between the programmes, and the strengths and challenges in these programmes. A literature search was performed using six scientific databases to identify any systematic reviews, literature reviews or relevant articles on the topic. Additional searches included journal articles and text references from 1995 to 2011. The search was conducted during December 2010 and November 2011. Included in this review are a total of 28 articles, which are focused around five major issues in paramedic education: (i) principle on paramedic programmes and the involvement of industry partners; (ii) clinical placements; (iii) contemporary methods of education; (iv) needs for specific programmes within paramedic education; and (v) articles related to the accreditation process for paramedic programmes. Paramedic programmes across Australian universities vary with many different practices, especially relating to clinical placements in the field. The further advances of the paramedic education programmes should aim to respond to population change and industry development, which would enhance the paramedic profession across Australia. © 2012 The Authors.

    The Australian Bluelink collaboration between CSIRO, the Bureau of Meteorology and the Royal Australian Navy has made available to the research community the output of BODAS (Bluelink ocean data assimilation system), an ensemble optimal interpolation reanalysis system with ~10 km resolution around Australia. Within the Bluelink project, BODAS fields are assimilated into a dynamic ocean model of the same resolution to produce BRAN (BlueLink ReANalysis, a hindcast of water properties around Australia from 1992 to 2004). In this study, BODAS hydrographic fields are assimilated into a ~ 3 km resolution Princeton Ocean Model (POM) configuration of the coastal ocean off SE Australia. Experiments were undertaken to establish the optimal strength and duration of the assimilation of BODAS fields into the 3 km resolution POM configuration for the purpose of producing hindcasts of ocean state. It is shown that the resultant downscaling of Bluelink products is better able to reproduce coastal features, particularly velocities and hydrography over the continental shelf off south eastern Australia. The BODAS-POM modelling system is used to provide a high-resolution simulation of the East Australian Current over the period 1992 to 2004. One of the applications that we will present is an investigation of the seasonal and inter-annual variability in the dispersion of passive particles in the East Australian Current. The practical outcome is an estimate of the connectivity of estuaries along the coast of southeast Australia, which is relevant for the dispersion of marine pests.

    We use an absolute and relative plate motion model for the plates around Australia to identify major plate tectonic events, evaluate their causes, and investigate their effects on anomalous intraplate subsidence or uplift and on the history of oceanic crustal accretion. An event at ˜136 Ma is marked by the onset of sea floor spreading between Greater India and Australia. At about this time long-lived subduction east of Australia ceased, probably due to subduction of the Phoenix-Pacific spreading ridge, changing this plate boundary to a transform margin. Between 130 and 80 Ma, Australia and East Antarctica moved eastward in the Atlantic-Indian mantle hotspot reference frame. This can be plausibly linked to ridge push from the NW-SE oriented spreading center NW of Australia and to the inferred geometry and continued subduction of the Phoenix plate beneath the West Antarctic margin. A drastic change in spreading direction between the Indian and Australian plates from NE-SW to N-S occurred at about 99 Ma, possibly caused by a change in absolute motion of the Pacific Plate. Chron 27 (˜61 Ma) marks the onset of relative motion between East and West Antarctica, and a change in the relative motion between Australia and Antarctica. It may be linked to the subduction of a segment of the Neo-Tethyan Ridge. Both events caused anomalous subsidence on the Northwest Shelf of Australia. The almost stationary position of Australia w.r.t. the mantle from ˜80 Ma to ˜40 Ma may reflect the progressive subduction of the Pacific-Phoenix ridge to the east of New Zealand preceding 80 Ma, resulting in a diminished trench suction force east of Australia. Preliminary reconstructions to close the Pacific-Australian plate circuit based on recently collected geophysical data indicate that a tectonic event at 43 Ma may mark the onset of renewed subduction east of Australia. At the same time spreading in the Wharton Basin between India and Australia ceased, and tectonic reactivation is

    Larval production and recruitment underpin the maintenance of coral populations, but these early life history stages are vulnerable to extreme variation in physical conditions. Environmental managers aim to minimise human impacts during significant periods of larval production and recruitment on reefs, but doing so requires knowledge of the modes and timing of coral reproduction. Most corals are hermaphroditic or gonochoric, with a brooding or broadcast spawning mode of reproduction. Brooding corals are a significant component of some reefs and produce larvae over consecutive months. Broadcast spawning corals are more common and display considerable variation in their patterns of spawning among reefs. Highly synchronous spawning can occur on reefs around Australia, particularly on the Great Barrier Reef. On Australia's remote north-west coast there have been fewer studies of coral reproduction. The recent industrial expansion into these regions has facilitated research, but the associated data are often contained within confidential reports. Here we combine information in this grey-literature with that available publicly to update our knowledge of coral reproduction in WA, for tens of thousands of corals and hundreds of species from over a dozen reefs spanning 20° of latitude. We identified broad patterns in coral reproduction, but more detailed insights were hindered by biased sampling; most studies focused on species of Acropora sampled over a few months at several reefs. Within the existing data, there was a latitudinal gradient in spawning activity among seasons, with mass spawning during autumn occurring on all reefs (but the temperate south-west). Participation in a smaller, multi-specific spawning during spring decreased from approximately one quarter of corals on the Kimberley Oceanic reefs to little participation at Ningaloo. Within these seasons, spawning was concentrated in March and/or April, and October and/or November, depending on the timing of the

    Since 1995, a large region of Australia has been gripped by the most severe drought in living memory, the so-called ``Big Dry''. The ramifications for affected regions are dire, with acute water shortages for rural and metropolitan areas, record agricultural losses, the drying-out of two of Australia's major river systems and far-reaching ecosystem damage. Yet the drought's origins have remained elusive. For Southeast Australia, we show here that the ``Big Dry'' and other iconic 20th Century droughts, including the Federation Drought (1895-1902) and World War II drought (1937-1945), are driven by Indian Ocean variability, not Pacific Ocean conditions as traditionally assumed. Specifically, a conspicuous absence of Indian Ocean temperature conditions conducive to enhanced tropical moisture transport has deprived southeastern Australia of its normal rainfall quota. In the case of the ``Big Dry'', its unprecedented intensity is also related to recent higher temperatures.

    Population-based surveillance for candidemia in Australia from 2001 to 2004 identified 1,095 cases. Annual overall and hospital-specific incidences were 1.81/100,000 and 0.21/1,000 separations (completed admissions), respectively. Predisposing factors included malignancy (32.1%), indwelling vascular catheters (72.6%), use of antimicrobial agents (77%), and surgery (37.1%). Of 919 episodes, 81.5% were inpatient healthcare associated (IHCA), 11.6% were outpatient healthcare associated (OHCA), and 6.9% were community acquired (CA). Concomitant illnesses and risk factors were similar in IHCA and OHCA candidemia. IHCA candidemia was associated with sepsis at diagnosis (p<0.001), death <30 days after infection (p<0.001), and prolonged hospital admission (p<0.001). Non–Candida albicans species (52.7%) caused 60.5% of cases acquired outside hospitals and 49.9% of IHCA candidemia (p = 0.02). The 30-day death rate was 27.7% in those >65 years of age. Adult critical care stay, sepsis syndrome, and corticosteroid therapy were associated with the greatest risk for death. Systematic epidemiologic studies that use standardized definitions for IHCA, OHCA, and CA candidemia are indicated. PMID:17176564

    The need for increasingly widespread application of a policy or program, settlement, and multiculturalism is urgent in both Canada and Australia. For both countries there is a clear pattern of coalescence and divergence and the distinct growth of immigration as a federal function. While Australia has strengthened federal functions in a area of increasingly geo-political need, Canada is moving towards a looser model of federalism. By 1918 both countries were strengthening their federal functions in immigration as discussions within the British Empire on the recommendations of the 1917 Dominions Royal Commission took root. Both countries were interested in agricultural immigration and land settlement. The Great Depression caused a major reduction in population growth rates. From 1933-1948 Canada had a poor record of providing sanctuary for Jews. In Australia, however, Jewish voluntary agencies were aiding the reception of refugees by 1937. The 1st permanent embodiment of commonwealth jurisdiction over immigration was the establishment of an Immigration Branch within the Department of Interior around 1938. Australia needed extra population for defense. The major structural link between government and the immigrant communities was through the Good Neighbor Movement, which began on a nationwide basis in 1950. Both Canada and Australia are major receiving countries for refugees. In 1973 Australia reached the position of effective, practical nondiscrimination achieved by Canada in 1967. Prime Minister Trudeau's policy was multiculturalism within a framework of bilingualism. By 1978 Australia had a new federalism policy, which in all areas concerned with immigrants, refugees and ethnicity, rationalized resources allocation and imposed a political philosophy. The foci of multiculturalism in Australia are 1) community languages; 2) creation of a tolerant, non-discriminatory society; and 3) equity and participation. In 1978 Australia specified population replacement and

    There has been a proliferation of quality use of medicines activities in Australia since the 1990s. However, knowledge of the nature and extent of these activities was lacking. A mechanism was required to map the activities to enable their coordination. To develop a geographical mapping facility as an evaluative tool to assist the planning and implementation of Australia's policy on the quality use of medicines. A web-based database incorporating geographical mapping software was developed. Quality use of medicines projects implemented across the country was identified from project listings funded by the Quality Use of Medicines Evaluation Program, the National Health and Medical Research Council, Mental Health Strategy, Rural Health Support, Education and Training Program, the Healthy Seniors Initiative, the General Practice Evaluation Program and the Drug Utilisation Evaluation Network. In addition, projects were identified through direct mail to persons working in the field. The Quality Use of Medicines Mapping Project (QUMMP) was developed, providing a Web-based database that can be continuously updated. This database showed the distribution of quality use of medicines activities by: (i) geographical region, (ii) project type, (iii) target group, (iv) stakeholder involvement, (v) funding body and (vi) evaluation method. At September 2001, the database included 901 projects. Sixty-two per cent of projects had been conducted in Australian capital cities, where approximately 63% of the population reside. Distribution of projects varied between States. In Western Australia and Queensland, 36 and 73 projects had been conducted, respectively, representing approximately two projects per 100,000 people. By comparison, in South Australia and Tasmania approximately seven projects per 100,000 people were recorded, with six per 100,000 people in Victoria and three per 100,000 people in New South Wales.

    Bacteraemias in children are an important cause of morbidity and mortality. Knowledge of local epidemiology and trends is important to inform practitioners of likely pathogens in the sick child. This study aimed to determine trends over time in pathogenic organisms causing paediatric bacteraemia in North Queensland and to audit a hospital's blood culture results with respect to contamination rate. This was a retrospective review of 8385 blood cultures collected from children attending a tertiary centre in North Queensland over a 10-year period (2001-2010). There were 696 positive blood cultures (8.3%) with 70 different bacterial species detected. Gram-positive and Gram-negative bacteria accounted for 48.6% and 51.4% of isolates, respectively. Overall, bacteraemia accounted for 4.7 per 1000 admissions. The rate of contamination was 60.6% among positive blood cultures and 5.0% for all blood cultures sampled. These results were compared with previous published reports. Notable differences were seen in the frequencies of Salmonella and group A Streptococcus bacteraemias in North Queensland when compared with other reports. There was also a decline in vaccine-preventable infections such as S. pneumoniae and an increasing trend of community-acquired MRSA bacteraemia. This study has demonstrated the unique profile of causative pathogens of paediatric bacteraemias in tropical Australia. In light of the increasing prevalence of MRSA, empiric treatment for sepsis for children in this region needs to be reconsidered. © 2014 The Authors.

  5. Contemporary vocational rehabilitation in Australia.

    Buys, Nicholas; Matthews, Lynda R; Randall, Christine

    2015-01-01

    There is a strong connection between disability and decreased participation rates in the Australian labour market. Australian government policy recognises vocational rehabilitation as a key strategy to increase employment rates of people with disabilities. This paper examines current Australian disability employment policies and practices. It also reviews vocational rehabilitation competency research to identify knowledge and skill domains central to quality service provision, and explores the delivery of tertiary level vocational rehabilitation education. Policy changes in Australia over the last decade have been aimed at addressing the unsustainable increase in disability benefits. In this context vocational rehabilitation services continue to be viewed as crucial in assisting people with disabilities to maintain employment and reduce disengagement. Competencies research has consistently identified vocational counselling, personal counselling, professional practice and case management as central to quality vocational rehabilitation service provision. Two competencies identified in recent research, workplace disability case management and workplace interventions and program management, reflect the centrality of vocational rehabilitation to disability management. Changes in the policy environment to reduce the number of disability pension recipients will inevitably lead to an increased demand for trained vocational rehabilitation personnel. Given the development of strong accreditation standards for vocational rehabilitation education and practice that underpin the provision of tertiary level rehabilitation counselling training programs, professionally qualified rehabilitation counsellors are ideally placed to address the complex employment needs of people with a disability. It is important to understand changes that may occur in policy environments in terms of their impact on vocational rehabilitation service delivery for people with disabilities. Variable levels

    2006-01-01

    OBJECTIVE: Many countries are implementing measles elimination strategies. In Australia, the State of Victoria has conducted enhanced measles surveillance since 1997 using case interviews and home-based specimen collection for laboratory confirmation. We attempted to identify features of notified cases that would better target surveillance resources. METHODS: We retrospectively classified notifications received from 1998 to 2003 as having been received in an epidemic (one or more laboratory-confirmed cases) or an interepidemic period (no laboratory-confirmed cases). We labelled the first case notified in any epidemic period that was not laboratory-confirmed at the time of notification as a "sentinel case". To maximize detection of sentinel cases while minimizing the follow-up of eventually discarded notifications, we generated algorithms using sentinel cases and interepidemic notifications. FINDINGS: We identified 10 sentinel cases with 422 interepidemic notifications from 1281 Victorian notifications. Sentinel cases were more likely to report fever at rash onset (odds ratio (OR) 15.7, 95% confidence interval (CI) CI: 2.1-688.9), cough (OR 10.4, 95% CI: 1.4-456.7), conjunctivitis (OR 7.9, 95% CI: 1.8-39.1), or year of birth between 1968 and 1981 (OR 31.8, 95% CI: 6.7-162.3). Prospective application of an algorithm consisting of fever at rash onset or born between 1968 and 1981 in the review period would have detected all sentinel cases and avoided the need for enhanced follow-up of 162 of the 422 eventually discarded notifications. CONCLUSION: Elimination strategies should be refined to suit regional and local priorities. The prospective application of an algorithm in Victoria is likely to reduce enhanced measles surveillance resource use in interepidemic periods, while still detecting early cases during measles outbreaks.

    2004-01-01

    The Multi-angle Imaging SpectroRadiometer (MISR) acquired these natural color images and cloud top height measurements for Monty before and after the storm made landfall over the remote Pilbara region of Western Australia, on February 29 and March 2, 2004 (shown as the left and right-hand image sets, respectively). On February 29, Monty was upgraded to category 4 cyclone status. After traveling inland about 300 kilometers to the south, the cyclonic circulation had decayed considerably, although category 3 force winds were reported on the ground. Some parts of the drought-affected Pilbara region received more than 300 millimeters of rainfall, and serious and extensive flooding has occurred.

    The natural color images cover much of the same area, although the right-hand panels are offset slightly to the east. Automated stereoscopic processing of data from multiple MISR cameras was utilized to produce the cloud-top height fields. The distinctive spatial patterns of the clouds provide the necessary contrast to enable automated feature matching between images acquired at different view angles. The height retrievals are at this stage uncorrected for the effects of the high winds associated with cyclone rotation. Areas where heights could not be retrieved are shown in dark gray.

    The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. These data products were generated from a portion of the imagery acquired during Terra orbits 22335 and 22364. The panels cover an area of about 380 kilometers x 985 kilometers, and utilize data from blocks 105 to 111 within World Reference System-2 paths 115 and 113.

    MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the

    The Endocrine Society of Australia was formed in 1958 with the aims of advancing knowledge and practice in endocrinology (the study of hormones) and to bring together physicians and scientists in this area of study. It was one of the first medical specialist societies in Australia. From humble beginnings with ninety-nine foundation members, it has flourished to a society with almost 950 members which annually runs three successful clinical and scientific meetings, and provides scholarships, research grants, and travel grants for its young members. Members have received international and national recognition within the field and more generally. Collaboration between scientists and physicians has been a key strength of the Society.

    Tick bites in Australia can lead to a variety of illnesses in patients. These include infection, allergies, paralysis, autoimmune disease, post-infection fatigue and Australian multisystem disorder. Rickettsial (Rickettsia spp.) infections (Queensland tick typhus, Flinders Island spotted fever and Australian spotted fever) and Q fever (Coxiella burnetii) are the only systemic bacterial infections that are known to be transmitted by tick bites in Australia. Three species of local ticks transmit bacterial infection following a tick bite: the paralysis tick (Ixodes holocyclus) is endemic on the east coast of Australia and causes Queensland tick typhus due to R. australis and Q fever due to C. burnetii; the ornate kangaroo tick (Amblyomma triguttatum) occurs throughout much of northern, central and western Australia and causes Q fever; and the southern reptile tick (Bothriocroton hydrosauri) is found mainly in south-eastern Australia and causes Flinders Island spotted fever due to R. honei. Much about Australian ticks and the medical outcomes following tick bites remains unknown. Further research is required to increase understanding of these areas.

  19. Does Lyme disease exist in Australia?

    PubMed

    Collignon, Peter J; Lum, Gary D; Robson, Jennifer Mb

    2016-11-07

    There is no convincing evidence that classic Lyme disease occurs in Australia, nor is there evidence that the causative agent, Borrelia burgdorferi, is found in Australian animals or ticks. Lyme disease, however, can be acquired overseas but diagnosed in Australia; most people presenting with laboratory-confirmed Lyme disease in Australia were infected in Europe. Despite the lack of evidence that Lyme disease can be acquired in Australia, growing numbers of patients, their supporters, and some politicians demand diagnoses and treatment according to the protocols of the "chronic Lyme disease" school of thought. Antibiotic therapy for chronic "Lyme disease-like illness" can cause harm to both the individual (eg, cannula-related intravenous sepsis) and the broader community (increased antimicrobial resistance rates). Until there is strong evidence from well performed clinical studies that bacteria present in Australia cause a chronic debilitating illness that responds to prolonged antibiotics, treating patients with "Lyme disease-like illness" with prolonged antibiotic therapy is unjustified, and is likely to do much more harm than good.

  20. Coral reproduction in Western Australia

    Speed, Conrad W.; Babcock, Russ

    Larval production and recruitment underpin the maintenance of coral populations, but these early life history stages are vulnerable to extreme variation in physical conditions. Environmental managers aim to minimise human impacts during significant periods of larval production and recruitment on reefs, but doing so requires knowledge of the modes and timing of coral reproduction. Most corals are hermaphroditic or gonochoric, with a brooding or broadcast spawning mode of reproduction. Brooding corals are a significant component of some reefs and produce larvae over consecutive months. Broadcast spawning corals are more common and display considerable variation in their patterns of spawning among reefs. Highly synchronous spawning can occur on reefs around Australia, particularly on the Great Barrier Reef. On Australia’s remote north-west coast there have been fewer studies of coral reproduction. The recent industrial expansion into these regions has facilitated research, but the associated data are often contained within confidential reports. Here we combine information in this grey-literature with that available publicly to update our knowledge of coral reproduction in WA, for tens of thousands of corals and hundreds of species from over a dozen reefs spanning 20° of latitude. We identified broad patterns in coral reproduction, but more detailed insights were hindered by biased sampling; most studies focused on species of Acropora sampled over a few months at several reefs. Within the existing data, there was a latitudinal gradient in spawning activity among seasons, with mass spawning during autumn occurring on all reefs (but the temperate south-west). Participation in a smaller, multi-specific spawning during spring decreased from approximately one quarter of corals on the Kimberley Oceanic reefs to little participation at Ningaloo. Within these seasons, spawning was concentrated in March and/or April, and October and/or November, depending on the timing of

    NASA image acquired April 18 - October 23, 2012 This image of Asia and Australia at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012. The new data was mapped over existing Blue Marble imagery of Earth to provide a realistic view of the planet. The nighttime view was made possible by the new satellite’s “day-night band” of the Visible Infrared Imaging Radiometer Suite. VIIRS detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as city lights, gas flares, auroras, wildfires, and reflected moonlight. In this case, auroras, fires, and other stray light have been removed to emphasize the city lights. “Night time imagery provides an intuitively graspable view of our planet,” says William Stefanov, a scientist in NASA’s International Space Station program office who has worked with similar images from astronauts. “City lights are an excellent means to track urban and suburban growth, which feeds into planning for energy use and urban hazards, for studying urban heat islands, and for initializing climate models.” Named for satellite meteorology pioneer Verner Suomi, NPP flies over any given point on Earth's surface twice each day at roughly 1:30 a.m. and p.m. The polar-orbiting satellite flies 824 kilometers (512 miles) above the surface, sending its data once per orbit to a ground station in Svalbard, Norway, and continuously to local direct broadcast users distributed around the world. The mission is managed by NASA with operational support from NOAA and its Joint Polar Satellite System, which manages the satellite's ground system.

    Despite an apparent increase in cases of angiostrongyliasis in humans and animals in Australia, the epidemiology of infection with the two species of Angiostrongylus that co-exist in this country, namely A. cantonensis and A. mackerrasae, is poorly understood. This knowledge gap is particularly important with respect to A. mackerrasae, a species evidently native to Australia, as its ability to cause disease in humans is unknown. Likewise, there is little information on the roles of native and introduced species of rodents and molluscs as hosts of Angiostrongylus species in Australia. This review focuses on the gaps in the knowledge about the two species, highlighting the need for epidemiological and pathogenesis studies on the native lungworm A. mackerrasae.

    Development in 1989 of Seahorse and Tarwhine fields in the Bass Strait, offshore Australia, promoted the first reeled installation of the thermally insulated pipeline system known as pipe-in-pipe (PIP). This paper reports that this system consists of an inner steel pipe coated with high-density polyurethane (HDPU) foam inside an outer steel carrier pipe. The offshore lines for which PIP was finally chosen are 7 and 10.8 miles, respectively, connecting the Barracouta offshore platform and subsea wellheads at each field location. Several alternative coating systems were evaluated, as report in Part 1 of this series. This conclusion chronicles coating application and shore fabrication of PIP for this project.

    The status of women in physics is Australia has remained mostly steady until recently, with the appointment of several eminent women in major government of public roles. Australia seems to maintain the same gender ratio for those studying and working in physics. There is no overall coordination of programs to assist women into the workplace but there is generally goodwill. Success in attracting and retaining women in the physics workforce appears to depend on the local culture, initiatives, and attitude of the most senior person in the organization.

    Australia and New Zealand share in part a history in the Gondwana supercontinent. Australia has a long and complex tectonic history with the last major accretion in the early Paleozoic, whereas New Zealand is still undergoing major plate boundary processes. The Australian continent is relatively well covered with both active and passive seismic techniques. Multiple sources of information are therefore available for building a model of Moho depth. Results from on-shore and off-shore refraction experiments are supplemented by receiver functions from a large number of portable stations and the recently augmented set of permanent stations. Moho picks from more than 10 500 km of full-crustal reflection profiles provide valuable additional constraints. The composite data set provides good sampling of much of Australia, though coverage remains low in some remote desert areas. The various datasets provide multiple estimates of the depth to Moho in many regions, and the consistency between the different techniques is high. Some of the thinnest crust lies beneath the Archean craton in the Pilbara, and in the neighbourhood of the Simpson desert. Thick crust is encountered beneath parts of the Proterozoic in Central Australia, and beneath the Paleozoic Lachlan fold belt in southeastern Australia. There are a number of zones of sharp contrast in depth to Moho, notably in the southern part of Central Australia. Despite most of the continental material around New Zealand being submerged, Moho data for this region is mainly onshore concentrating on the Australia-Pacific plate boundary. Two major wide-angle reflection transects provide the bulk of the active source data with just a few traditional reflection profiles offshore. The plate boundary provides an abundance of local earthquakes for tomographic imaging and this data is supplemented with receiver functions from both portable and permanent networks. Onshore the combined coverage is as dense as that of Australia, although it

    We aimed to identify regional centres of plant biodiversity in South Australia, a sub-continental land area of 983,482 km2, by mapping a suite of metrics. Broad-brush conservation issues associated with the centres were mapped, specifically climate sensitivity, exposure to habitat fragmentation, introduced species and altered fire regimes. We compiled 727,417 plant species records from plot-based field surveys and herbarium records and mapped the following: species richness (all species; South Australian endemics; conservation-dependent species; introduced species); georeferenced weighted endemism, phylogenetic diversity, georeferenced phylogenetic endemism; and measures of beta diversity at local and state-wide scales. Associated conservation issues mapped were: climate sensitivity measured via ordination and non-linear modelling; habitat fragmentation represented by the proportion of remnant vegetation within a moving window; fire prone landscapes assessed using fire history records; invasive species assessed through diversity metrics, species distribution and literature. Compared to plots, herbarium data had higher spatial and taxonomic coverage but records were more biased towards major transport corridors. Beta diversity was influenced by sampling intensity and scale of comparison. We identified six centres of high plant biodiversity for South Australia: Western Kangaroo Island; Southern Mount Lofty Ranges; Anangu Pitjantjatjara Yankunytjatjara lands; Southern Flinders Ranges; Southern Eyre Peninsula; Lower South East. Species composition in the arid-mediterranean ecotone was the most climate sensitive. Fragmentation mapping highlighted the dichotomy between extensive land-use and high remnancy in the north and intensive land-use and low remnancy in the south. Invasive species were most species rich in agricultural areas close to population centres. Fire mapping revealed large variation in frequency across the state. Biodiversity scores were not always

    The residents of rural and regional Australia have less access to health care services than in capital cities. There is a reluctance of General Practitioners to practice in the country. New information technology and government initiatives are now addressing this problem. High bandwidth videoconferencing is now being routinely used to provide psychiatric consultations to areas without this service. But this (like many other implementations of telecommunication technologies to health) has resulted in loss of revenue to regional Australia while benefiting capital cities. Thus, the current implementation of telecommunication technology to health has resulted in loss of revenue of the regions while increasing the bias towards the cities. Further, the system is not economically viable and requires the Government to inject funds for the smooth operation of the system. This paper proposes the use of telecommunication technology for enabling the communities of regional Australia to access health facilities via physical and virtual clinics. The proposed technique is self supporting and is based in the country with the intent to prevent the drain of resources from regional Australia. The technique attempts to eradicate the problem at the root level by providing a business opportunity that is based in and to cater for the needs of the remote communities. The proposed system would provide health services by physical and virtual clinics and while serving the communities would be profit centres- and thus attracting doctors and other resources to the remote communities.

    Artificial tanning, defined as deliberate exposure to ultraviolet rays produced by artificial tanning devices, is a new and emerging public health issue in Australia and globally. Epidemiological research suggests that artificial tanning may contribute to the incidence of melanoma, nonmelanoma skin cancer as well as other health problems. Given that Australia has a high incidence of skin cancer, we have undertaken a study to explore how artificial tanning has been promoted to its users. The aim was to analyze the completeness and accuracy of information about artificial tanning. A content analysis of web sites of tanning salons and distributors of tanning equipment in Australia was conducted. A total of 22 web sites were analyzed. None of the solarium operators or distributors of equipment provided full information about the risks of artificial tanning. Fifty-nine percent of web advertisements had no information and 41% provided only partial information regarding the risks of artificial tanning. Pictures with the image of bronze-tanned bodies, predominantly women, were used by all web advertisers. In light of the success of sun-safety campaigns in Australia, the findings of future epidemiological research on the prevalence of artificial tanning and sociological and anthropological research on why people utilize artificial tanning should be a basis for developing effective targeted health promotion on the elimination of artificial tanning in the country.

  6. Remote access laboratories in Australia and Europe

    NASA Astrophysics Data System (ADS)

    Ku, H.; Ahfock, T.; Yusaf, T.

    2011-06-01

    Remote access laboratories (RALs) were first developed in 1994 in Australia and Switzerland. The main purposes of developing them are to enable students to do their experiments at their own pace, time and locations and to enable students and teaching staff to get access to facilities beyond their institutions. Currently, most of the experiments carried out through RALs in Australia are heavily biased towards electrical, electronic and computer engineering disciplines. However, the experiments carried out through RALs in Europe had more variety, in addition to the traditional electrical, electronic and computer engineering disciplines, there were experiments in mechanical and mechatronic disciplines. It was found that RALs are now being developed aggressively in Australia and Europe and it can be argued that RALs will develop further and faster in the future with improving Internet technology. The rising costs of real experimental equipment will also speed up their development because by making the equipment remotely accessible, the cost can be shared by more universities or institutions and this will improve their cost-effectiveness. Their development would be particularly rapid in large countries with small populations such as Australia, Canada and Russia, because of the scale of economy. Reusability of software, interoperability in software implementation, computer supported collaborative learning and convergence with learning management systems are the required development of future RALs.

  14. Labour market outcomes of public health graduates: evidence from Australia.

    PubMed

    Li, Ian W; Awofeso, Niyi

    2014-09-01

    Little information is available on the public health workforce. This study contributes to the gap in the literature and examines the demographic characteristics, career destinations and earnings of Masters in Public Health (MPH) graduates in Australia, using data from the 1999-2009 waves of the Graduate Destination Survey. It was found that public health graduates had a high amount of female representation and very low proportions of indigenous representation. Public health graduates experienced a relatively low unemployment rate and 85% were employed within 120 days of graduation. However, close to half of the graduates did not work in the health industry or in health-related roles. The mean salaries of public health graduates working in public health roles were relatively low compared to those in other occupations, but they had a range comparable to that observed for public health professionals in the USA and were higher than those of other Masters graduates in some other health fields. The results indicate strong demand and positive employment prospects for public health graduates in Australia. Strategies to target recruitment and/or retention of female or indigenous graduates in the public health workforce should be a priority. Mapping of public health graduate destinations and employment prospects should might be prioritised, given its strong potential to facilitate workforce planning and provide potential public health workers with more comprehensive career trajectories. © Royal Society for Public Health 2013.

  5. Floodflow frequency model selection in Australia

    NASA Astrophysics Data System (ADS)

    Vogel, Richard M.; McMahon, Thomas A.; Chiew, Francis H. S.

    1993-06-01

    Uniform flood frequency guidelines in Australia and the United States recommend the use of the log Pearson type 3 (LP3) distribution in flood frequency investigations. Many investigators have suggested alternate models such as the Generalized Extreme Value (GEV) distribution as an improvement over the LP3 distribution. Using floodflow data at 61 sites across Australia, we explore the suitability of various flood frequency models using L-moment diagrams. We also repeat the experiment performed in the original US Water Resource Council report (Bulletin 17B) which led to the LP3 mandate in the United States. Our evaluations reveal that among the models tested, the GEV and Wakeby distributions provide the best approximation to floodflow data in the regions of Australia that are dominated by rainfall during the winter months, such as southwest Western Australia and Tasmania. For the remainder of the continent, the Generalized Pareto (GPA) and Wakeby distributions provide the best approximation to floodflow data. The two- and three-parameter log-normal models and the LP3 distribution performed satisfactorily, yet not as well as either the GEV or GPA distributions. Other models such as the Gumbel, log-normal, normal, Pearson, exponential, and uniform distributions are shown to perform poorly. Recent research indicates that regional index-flood type procedures should be more accurate and more robust than the type of at-site procedures evaluated here. Nevertheless, this study reveals that index-flood procedures should not be restricted to a single distribution such as the GEV distribution because other distributions such as the GPA distribution perform significantly better in the most densely populated regions of Australia.

  6. Potential seen in areas off Northwest, Southeast Australia

    SciTech Connect

    Williamson, P.E.

    1997-11-24

    Effective with its 1997 release of offshore acreage, Australia launched a new system of offering two groups of areas with different closing dates. In the group for which bids close in March 1998: the Brose basin, which has supergiant gas reserves and now the major Cornea oil discovery, has the potential for more major discoveries in moderate to deep water between the petroleum kitchens and basin margin fields; elsewhere, shallow water, underexplored parts of the oil productive Bonaparte basin have intriguing oil and gas shows, noncommercial discoveries, and seismic anomalies. Small and large companies, with bids guaranteed by seismic-only to multiwell work programs, were successful in gaining exploration permits from the previous bidding round. The paper describes the bidding areas, the Southern Timar Sea, and the Petrel sub-basin.

  7. Developing a high-resolution regional atmospheric reanalysis for Australia

    2017-04-01

    A dynamically consistent, long-term atmospheric reanalysis can be used to support high-quality assessments of environmental risk and likelihood of extreme events. Most reanalyses are presently based on coarse-scale global systems that are not suitable for regional assessments in fire risk, water and natural resources, amongst others. The Australian Bureau of Meteorology is currently working to close this gap by producing a high-resolution reanalysis over the Australian and New Zealand region to construct a sequence of atmospheric conditions at sub-hourly intervals over the past 25 years from 1990. The Australia reanalysis consists of a convective-scale analysis nested within a 12 km regional-scale reanalysis, which is bounded by a coarse-scale ERA-Interim reanalysis that provides the required boundary and initial conditions. We use an unchanging atmospheric modelling suite based on the UERRA system used at the UK Met Office and the more recent version of the Bureau of Meteorology's operational numerical prediction model used in ACCESS-R (Australian Community Climate and Earth-System Simulator-Regional system). An advanced (4-dimensional variational) data assimilation scheme is used to optimally combine model physics with multiple observations from aircrafts, sondes, surface observations and satellites to create a best estimate of state of the atmosphere over a 6-hour moving window. This analysis is in turn used to drive a higher-resolution (1.5 km) downscaling model over selected subdomains within Australia, currently eastern New South Wales and Tasmania, with the capability to support this anywhere in the Australia-New Zealand domain. The temporal resolution of the gridded analysis fields for both the regional and higher-resolution subdomains are generally one hour, with many fields such as 10 m winds and 2 m temperatures available every 10 minutes. The reanalysis also produces many other variables that include wind, temperature, moisture, pressure, cloud cover

All three cases presented with ulceration in the limb; however, the classical sporotrichoid spread was present only in the first two cases. Their occurrence within several weeks of each other was suggestive of a common source of environmental contamination such as hay used as garden mulch. Diagnoses were delayed in each case, with each patient having substantial exposure to ineffective antibiotics before the correct diagnosis was made. These cases bring the total number of reported sporotrichosis cases in Australia since 1951 to 199. Lessons from these cases are to consider the diagnosis of sporotrichosis in lesions of typical appearance, even in geographical settings from where this pathogen has not previously been reported.

    Goat Paddock, a crater slightly over 5 km in diameter (18??20??? S, 126??40???E), lies at the north edge of the King Leopold Range/Mueller Range junction in the Kimberley district, Western Australia (Fig. 1). It was noted as a geological anomaly in 1964 during regional mapping by the Bureau of Mineral Resources, Geology and Geophysics and the Geological Survey of Western Australia. The possibility of its being a meteorite impact crater has been discussed1, although this suggestion was subsequently ignored2. Two holes were drilled by a mining corporation in 1972 to test whether kimberlite underlay the structure. Here we report the findings of five days of reconnaissance in August 1979 which established that Goat Paddock is a cryptoexplosion crater containing shocked rocks and an unusually well exposed set of structural features. ?? 1980 Nature Publishing Group.

    Trans Australia believes that its excellent accident rate record is due to a number of factors. It has a good group of standard operating procedures, and its crews are pretty well self-disciplined and adhere to those procedures. But the other thing that it believes is a factor in its safety record is that perhaps it is also due to its preparedness to be innovative, to keep up with what is going on in the rest of the world and, if it looks to have value, then to be amongst the first to try it out. Trans Australia commenced a program similar to Line Oriented Flight Training (LOFT) fairly early in 1979--that being its first windshear program-- which leads to why they are doing a course of resource management training, which we have chosen to call Aircrew Team Management (ATM). This course is detailed in another presentation.

  11. History of corneal transplantation in Australia.

    2015-04-01

    Corneal transplantation is a triumph of modern ophthalmology. The possibility of corneal transplantation was first raised in 1797 but a century passed before Zirm achieved the first successful penetrating graft in 1905. Gibson reported the first corneal graft in Australia from Brisbane in 1940 and English established the first eye bank there a few years later. Corneal transplantation evolved steadily over the twentieth century. In the second half of the century, developments in microsurgery, including surgical materials such as monofilament nylon and strong topical steroid drops, accounted for improvements in outcomes. In 2013, approximately 1500 corneal transplants were done in Australia. Eye banking has evolved to cope with the rising demands for donor corneas. Australian corneal surgeons collaborated to establish and support the Australian Corneal Graft Registry in 1985. It follows the outcomes of their surgery and has become an important international resource for surgeons seeking further improvement with the procedure.

    The Australian Anti-Dumping Authority (ADA0) has imposed dumping duties on imports of polyvinyl chloride (PVC) resin from seven countries and on certain expanded polystyrene (EPS) beads from Korea and Singapore. The decisions come at the end of two separate investigations begun earlier this year. In its first finding, the ADA concluded that there has been dumping of PVC resin from Canada, China, France, Japan, Norway, Saudi Arabia, and Thailand, which has caused and threatens to cause material injury to the domestic PVC industry. An eighth country, Romania, was found not to have been exporting PVC to Australia. The case is the second of its kind in Australia focusing on PVC. In December 1991 the ADA found in favor of local producer sin a dumping complaint against Argentina, Brazil, Hungary, Israel, Korea, Mexico, Poland, Singapore, Taiwan, and the US.

    Up to 2006 there was some improvement for women in physics in Australia; since then there has been a decline. Women are underrepresented in all aspects of physics education and work, including school, university, and research laboratories. In addition, women physicists usually have lower seniority and earn less. This scenario is compounded by recent inactivity of the Australian Institute of Physics women's group since December 2010.

    The lure of land and gold, the hope for better health and an overcrowded profession in Britain led to an increasing number of doctors migrating to Australia. This migration was even more marked after the goldrush, especially in Victoria. The fifth article in this series looks at the way in which medical practice was controlled by excluding many of those doctors who were from non-British origins.

    Understanding the spatial distribution of suicide can inform the planning, implementation and evaluation of suicide prevention activity. This study explored spatial clusters of suicide in Australia, and investigated likely socio-demographic determinants of these clusters. National suicide and population data at a statistical local area (SLA) level were obtained from the Australian Bureau of Statistics for the period of 1999 to 2003. Standardised mortality ratios (SMR) were calculated at the SLA level, and Geographic Information System (GIS) techniques were applied to investigate the geographical distribution of suicides and detect clusters of high risk in Australia. Male suicide incidence was relatively high in the northeast of Australia, and parts of the east coast, central and southeast inland, compared with the national average. Among the total male population and males aged 15 to 34, Mornington Shire had the whole or a part of primary high risk cluster for suicide, followed by the Bathurst-Melville area, one of the secondary clusters in the north coastal area of the Northern Territory. Other secondary clusters changed with the selection of cluster radius and age group. For males aged 35 to 54 years, only one cluster in the east of the country was identified. There was only one significant female suicide cluster near Melbourne while other SLAs had very few female suicide cases and were not identified as clusters. Male suicide clusters had a higher proportion of Indigenous population and lower median socio-economic index for area (SEIFA) than the national average, but their shapes changed with selection of maximum cluster radii setting. This study found high suicide risk clusters at the SLA level in Australia, which appeared to be associated with lower median socio-economic status and higher proportion of Indigenous population. Future suicide prevention programs should focus on these high risk areas.

    The aim of this paper is to identify certain important population trends among heroin users in Australia for the period 1971 - 97, such as: population growth, initiation, i.e. the number who were initiated to heroin in a given year, and quitting, i.e. the number that quit using heroin. For this purpose, we summarize and extract relevant characteristics from data from National Drug Strategy Household Survey (NDSHS 1998) conducted in Australia in 1998. We devise a systematic procedure to estimate historical trends from questions concerning past events. It is observed from our findings that the size of the heroin user population in Australia is in a sharp increase, especially from the early 1980s onwards. The general trend obtained for the period 1971 - 97 is strikingly similar to that obtained by Hall et al. (2000) for the dependent heroin user population in Australia, even though their study was based on different datasets and a different methodology. In our reconstruction of the time history we also detect a levelling-off prior to 1990. Initiation is also observed to be on a sharp increase. The latter trend is accompanied by a similar trend of quitting, perhaps indicating a relatively short heroin use career. A sharp decrease in both initiation and quitting is observed after 1990. In conclusion, in the case of the trend in the population of heroin users a high rate of growth has been identified that is consistent with the existing literature. In the process, we demonstrated that even a static survey such as NDSHS 1998 can, sometimes, be used to extract historical (dynamic) trends of certain important variables.

    Australian biobanks are largely autonomous and funded by local health care institutions, although some biobanks also receive funding from the National Health and Medical Research Council (NHMRC). There is no formal biobank legislation, but the NHMRC has developed biobanking guidelines. The regulation of biobanks is mainly through privacy laws and human research ethics committees. Australia is moving toward the use of broad consent for biobanking. International data sharing is permitted.

    The Glikson structural anomaly in western Australia is associated with a complex ring magnetic anomaly about 16 km in diameter. It is composed of many smaller anomalies arranged roughly like beads on a necklace. On the basis of reconnaissance observations, the ring anomaly evidently is more or less coincident with the ring structural depression. It is suggested that the magnetic anomaly is due to the presence of dolerite intruded along the axis of the ring structural depression.

    This paper presents results from the inaugural Scope of Practice Survey of Optometry Australia members conducted in October 2015. The survey gathered information related to confidence in detecting and diagnosing key ocular conditions, grading diabetic retinopathy, prescribing scheduled medicines, access to equipment, confidence using equipment, incidence of patients requiring therapeutic management, referral practices and services provided. The survey was developed, piloted, modified and administered to members of Optometry Australia (excluding student and retired members), who had a current email address. Results were collated and analysed using Microsoft Excel. Of the 587 optometrists in clinical practice who responded, 254 (43 per cent) had therapeutic endorsement of registration. The majority of respondents practised in a major city or surrounding suburbs (63 per cent). Independent practice was the most frequently cited practice type (58 per cent). The estimated average number of patients seen in a week was 48; there was a steady decrease in the number of patients per week with increasing age, from 53 for optometrists in their 20s to 27 for optometrists aged over 70. There was very high confidence (over 93 per cent) in ability to grade diabetic retinopathy and diagnose a range of ocular conditions. Confidence in performance of more advanced techniques was higher for endorsed than non-endorsed optometrists. Approximately 12 per cent of patients required a Schedule 4 therapeutic prescription. The most frequently recommended over-the-counter medications were for dry eye for both endorsed and non-endorsed optometrists. The most frequently prescribed Schedule 4 medications were anti-inflammatories. The most challenging conditions to prescribe for were glaucoma, microbial keratitis and uveitis. Approximately one in six therapeutically endorsed optometrists reported unexpected side effects of medications they had prescribed. Information from the survey will guide

    The population history of Aboriginal Australians remains largely uncharacterized. Here we generate high-coverage genomes for 83 Aboriginal Australians (speakers of Pama-Nyungan languages) and 25 Papuans from the New Guinea Highlands. We find that Papuan and Aboriginal Australian ancestors diversified 25-40 thousand years ago (kya), suggesting pre-Holocene population structure in the ancient continent of Sahul (Australia, New Guinea and Tasmania). However, all of the studied Aboriginal Australians descend from a single founding population that differentiated ~10-32 kya. We infer a population expansion in northeast Australia during the Holocene epoch (past 10,000 years) associated with limited gene flow from this region to the rest of Australia, consistent with the spread of the Pama-Nyungan languages. We estimate that Aboriginal Australians and Papuans diverged from Eurasians 51-72 kya, following a single out-of-Africa dispersal, and subsequently admixed with archaic populations. Finally, we report evidence of selection in Aboriginal Australians potentially associated with living in the desert.

    The sera of 271 pteropid bats (or flying foxes) collected from Queensland, New South Wales, Western Australia, and the Northern Territory were screened against a reference panel of 21 Leptospira spp. using the microscopic agglutination test (MAT). Sera were collected from December 1997 through August 1999. The MAT panel represented those serovars previously isolated in Australia, as well as exotic serovars found in neighboring countries. Leptospiral antibodies were detected in 75 (28%) of the sera and represented seven serovars, one of which, L. interrogans serovar cynopteri has been regarded as exotic to Australia. Sixty sera were reactive to one serovar, 12 sera were reactive to two serovars, and three sera were reactive to three serovars. The L. kirschneri serovar australis was most frequently identified (60.2%). The findings suggest a previously unrecognized role of pteropid bats in the natural history of leptospirosis. The potential exists for establishment of infection in new host species, the transmission of new serovars to known host species, and for changes in virulence of leptospires as a result of passage through these species.

  6. Gulf War illness: a view from Australia

    Australia sent a small, mostly naval, deployment to the 1991 Gulf War. When papers and media concerns arose about unexplained Gulf War illnesses in Gulf War troops from other countries, Australia decided to undertake its own study of Australian veterans. Undertaking a later study, more than 10 years after the Gulf War, allowed us to incorporate some methodological improvements on previous research, such as the inclusion of a face-to-face health assessment where more objective health data could be collected in addition to using a postal questionnaire. Despite the different Gulf War experience for the mostly naval Australian group, there were remarkable consistencies in the patterns of multiple symptom reporting found in overseas studies, including the fact that no unique symptom clusters were identified. In general, this excess symptom reporting was not found to occur with excesses in more objective measures of physical health. These objective physical measures included a wide range of haematological, biochemical and serological markers, a physical examination, spirometry and a step test of fatigability. In contrast, several psychological disorders, including anxiety, post-traumatic stress disorder, depression and substance abuse, were found to occur in excess in the Australian Gulf War group and were associated with Gulf War psychological stressors. These findings have helped raise awareness in Australia of psychological health problems in deployed military personnel. PMID:16687266

    In Australia, nurse practitioner (NP) services are a relatively new development with little being known about the prescribing practices of Australian NPs. The aim of this study was to conduct the first national study of Australian NP prescribing practices. Focus groups were conducted to inform construction of an electronic survey that was available for all NPs and NP candidates across Australia to complete. Seventy-two percent of authorized NPs and 39% of NP candidates reported that their practice involved prescribing pharmaceutical agents. Of those respondents who did prescribe during the course of their practice, 59% (n = 29) of the authorized NPs and 64% (n = 16) of the NP candidates reported that they usually prescribe at least once a day. The results from this study suggest that fewer Australian NPs prescribe than do NPs in the United States, and those who do prescribe do so less frequently. The current health policy framework in Australia while creating space for the role of the NP is restricting the role's utility and potential contribution to the health care of Australians.

    The paper describes the current position of shared decision making (SDM) within the Australian healthcare system. SDM POLICY IN AUSTRALIA: Support for SDM exists through guidelines and policy documents, and is strongly endorsed by consumer organisations; however, there is no clear overarching policy framework for SDM in Australia. TOOLS FOR SDM: There are limited tools available for SDM in clinical practice. Access to tools exists through some Australian health research and consumer organisation websites but the use of tools remains idiosyncratic. IMPLEMENTATION OF SDM: Comparatively little has been achieved in the implementation of SDM in Australia. Although there is wide recognition that consumer involvement in health decisions is important, provision of resources and infrastructure to achieve it is limited, and there is no clear strategy to support implementation within the healthcare system. SDM IN THE FUTURE: Current reforms to the healthcare system may enable a more centralised approach to implementation of SDM in the future. A new federally funded consumer health information organisation may assist by providing a central point through which SDM interventions may be made available to the Australian public and the Australian Charter of Rights has the potential to provide a national framework for consumer involvement. However, priority needs to be given to SDM by both federal and state governments with greater investment in SDM research and in activities to support implementation in clinical practice.

    Summer in southern Australia is the dry season, and in this true-color MODIS image of South Australia and the Spencer Gulf from October 20,2001, the area's vegetation is losing much of the lushness it possessed in the winter rainy season (See image from September 19, 2001). In southern hemisphere summer, the high pressure systems that dominate the continent's weather move south, and block the rain-bearing westerly winds. The resulting changes in seasonal rainfall are extreme. Many of the rivers are impermanent, and flow into dry or impermanent salt lakes, such as Lake Torrens (long, thin lake bed, roughly in the center of the image), and Lake Eyre (pink and white lake bed to the northwest of Torrens). Between the Eyre Peninsula (lower left) and the Yorke Peninsula further east lies the Spencer Gulf, showing the blue-green swirls that indicate a phytoplankton bloom. Australia gets less rainfall than any continent except Antarctica, and the low and seasonal flows contribute to problems with salinity and algal blooms in the continent's surface waters.

    Australia is a large, sparsely populated country with an economy based traditionally on raw materials exports. Though still a major international trader in minerals and agricultural products, Australia has suffered a decline in productivity, employment, exports, and economic growth since the 1950s. Most energy research and development (R and D) and policymaking activities are carried out under the National Energy Research, Development, and Demonstration (NERDD) program. The NERDD program priorities include, among others, production of liquid hydrocarbon fuels from natural gas or coal-derived synthesis gas and oil and gas exploration, assessment, and recovery technology (high priority); production of liquid fuels from coal and oil shale by hydrogenation or pyrolysis, coal gasification, and achievement of cost reductions in coal and oil shale exploration and assessment techniques (medium priority); and in-situ coal gasification (low priority). Bilateral agreements for energy R and D with other countries are carried out under the Australian Department of National Development and Energy. Australia currently has agreements related to oil, gas, shale, and coal liquids R and D with the UK, the US, Japan, and West Germany.

    In Australia, a number of managed entry agreements have been developed to enable national coverage of new medicines. Non-outcome based agreements are usually pricing arrangements that involve price or volume rebate agreements. In February 2013, there were at least 71 special pricing arrangements in place, including 26 for medicines restricted to use in hospitals. Health outcome based agreements can be made at the individual or population level. At the individual level, there were 28 medicines funded subject to continuation rules involving documentation of adequate benefit within the individual; some of these medicines also had price agreements in place. At the population level, only one outcome-based agreement has been implemented so far, for bosentan, a medicine marketed for pulmonary hypertension. In May 2010, a memorandum of understanding signed between the Australian Government and Medicines Australia, the peak pharmaceutical industry organisation, included the possibility for industry to request consideration of a 'Managed Entry Scheme' as part of the funding submission process for medicines with high clinical needs. It includes the possibility of a randomised controlled trial (RCT)-based entry scheme. Although this form of managed entry has yet not been trialed in Australia, several 2012/2013 funding recommendations included requests by the decision making committee for further evidence development.

    2015-05-01

    Scientific societies provide an important forum for scientists to meet and exchange ideas. In the early days of European settlement in Australia the few people interested in the sciences joined together to form societies that embraced all their individual disciplines. From 1888 the Australasian Association for the Advancement of Science with its different sections allowed a growing number of astronomers to share meetings only with researchers in the closely allied fields of mathematics and physics. Eventually, all three of these groups formed their own societies with the Astronomical Society of Australia (ASA) being the last in 1966. Archival records are used to illustrate how the formation of the ASA came about and to identify the people involved. The makeup of Australian astronomy at that period and some of its research fields are looked at, as well as the debates and discussions in the Society's first year while its future structure and role were established.

    During the 1950s and 1960s Australia was a world leader in the specialised field of low frequency radio astronomy, with two geographically-distinct areas of activity. One was in the Sydney region and the other in the island of Tasmania to the south of the Australian mainland. Research in the Sydney region began in 1949 through the CSIRO's Division of Radiophysics, and initially was carried out at the Hornsby Valley field station before later transferring to the Fleurs field station. In this paper we summarise the low frequency radio telescopes and research programs associated with the historic Hornsby Valley and Fleurs sites.

  15. Episodic behavior of Gondwanide deformation in eastern Australia: Insights from the Gympie Terrane

    Hoy, Derek; Rosenbaum, Gideon

    2017-08-01

    The mechanisms that drove Permian-Triassic orogenesis in Australia and throughout the Cordilleran-type Gondwanan margin is a subject of debate. Here we present field-based results on the structural evolution of the Gympie Terrane (eastern Australia), with the aim of evaluating its possible role in triggering widespread orogenesis. We document several deformation events (D1-D3) in the Gympie Terrane and show that the earliest deformation, D1, occurred only during the final pulse of orogenesis (235-230 Ma) within the broader Gondwanide Orogeny. In addition, we found no evidence for a crustal suture, suggesting that terrane accretion was not the main mechanism behind deformation. Rather, the similar spatiotemporal evolution of Permian-Triassic orogenic belts in Australia, Antarctica, South Africa, and South America suggest that the Gondwanide Orogeny was more likely linked to large-scale tectonic processes such as plate reorganization. In the context of previous work, our results highlight a number of spatial and temporal variations in pulses of deformation in eastern Australia, suggesting that shorter cycles of deformation occurred at a regional scale within the broader episode of the Gondwanide Orogeny. Similarly to the Cenozoic evolution of the central and southern Andes, we suggest that plate coupling and orogenic cycles in the Late Paleozoic to Early Mesozoic Gondwanide Orogeny have resulted from the superposition of mechanisms acting at a range of scales, perhaps contributing to the observed variations in the intensity, timing, and duration of deformation phases within the orogenic belt.

    Surface ultraviolet (UV) radiation plays an important role in human health. Increased exposure to UV radiation increases the risk of skin cancer. In Australia, public campaigns to prevent skin cancer include the promotion of daily UV forecasts. If all other atmospheric factors are equal, stratospheric ozone decreases result in UV increases. Given that Australia still has the highest skin cancer rates in the world, it is important to monitor Australia's stratospheric ozone and UV radiation levels over time because of the effects cumulative exposure can have on humans. In this paper, two long-term ozone datasets derived from surface and satellite measurements, a radiation code and atmospheric meteorological fields are used to calculate clear-sky UV radiation over a 50-year period (1959-2009) for Australia. The deviations from 1970-1980 levels show that clear-sky UV is on the rise. After the 1990s, an overall annual increase from 2 to 6% above the 1970-1980 levels was observed at all latitudes. Examining the summer and winter deviations from 1970-1980 showed that the winter signal dominated the annual changes, with winter increases almost twice those in summer. With ozone levels not expected to recover to pre-depletion levels until the middle of this century, UV levels are expected to continue to rise. Combined with Australians favoring an outdoor life-style, when temperatures are warmer, under high levels of UV, the associated risk of skin cancer will increase.

    Surface ultraviolet (UV) radiation plays an important role in human health. Increased exposure to UV radiation increases the risk of skin cancer. In Australia, public campaigns to prevent skin cancer include the promotion of daily UV forecasts. If all other atmospheric factors are equal, stratospheric ozone decreases result in UV increases. Given that Australia still has the highest skin cancer rates in the world, it is important to monitor Australia's stratospheric ozone and UV radiation levels over time because of the effects cumulative exposure can have on humans. In this paper, two long-term ozone datasets derived from surface and satellite measurements, a radiation code and atmospheric meteorological fields are used to calculate clear-sky UV radiation over a 50-year period (1959-2009) for Australia.

  18. Monitoring and adaptive resistance management in Australia for Bt-cotton: current status and future challenges.

    2007-07-01

    In the mid-1990 s the Australian Cotton industry adopted an insect-resistant variety of cotton (Ingard) which expresses the Bt toxin Cry1Ac that is specific to a group of insects including the target Helicoverpa armigera. A conservative resistance management plan (RMP), that restricted the area planted to Ingard, was implemented to preserve the efficacy of Cry1Ac until two-gene transgenic cotton was available. In 2004/05 Bollgard II replaced Ingard as the transgenic cotton available in Australia. It improves on Ingard by incorporating an additional insecticidal protein (Cry2Ab). If an appropriate refuge is grown, there is no restriction on the area planted to Bollgard II. In 2004/05 and 2005/06 the Bollgard II acreage represented approximately 80 of the total area planted to cotton in Australia. The sensitivity of field-collected populations of H. armigera to Bt products was assayed before and subsequent to the widespread deployment of Ingard cotton. In 2002 screens against Cry2Ab were developed in preparation for replacement of Ingard with Bollgard II. There have been no reported field failures of Bollgard II due to resistance. However, while alleles that confer resistance to H. armigera in the field are rare for Cry1Ac, they are surprisingly common for Cry2Ab. We present an overview of the current approach adopted in Australia to monitor and adaptively manage resistance to Bt-cotton in field populations of H. armigera and discuss the implications of our findings to date. We also highlight future challenges for resistance management in Australia, many of which extend to other Bt-crop and pest systems.

    1989-03-01

    In 1986, 21.3% of the population of Australia had been born overseas; currently, foreign born workers comprise 25% of the labor force. The level of skilled immigration has continued to increase throughout the 1980s. In the past, most English-speaking migrants gained recognition of their overseas qualifications, but about half of those from non-English speaking countries have never been able to return to their pre-migration occupations. Beginning with the medical field, occupational regulating gradually grew with state autonomy being a marked feature. Australia has 1 of the most highly regulated labor markets in the world, with hundreds of bodies to determine entry criteria. The Council of Overseas Professional Qualifications, established in 1969, guides selection and tests professionals both overseas and already resident in Australia. The Tradesmen's Rights Regulation Act recognizes acceptable tradesmen. Aside from these 2 bodies, the majority of qualifications are assessed at the state or local level. Problems skilled immigrants have encountered in attempting to gain recognition of their overseas qualifications include 1) preference for locally trained workers or discrimination against non-British/non-Australian qualifications; 2) lack of adequate information about assessment procedures; 3) inadequate use of interpreting and translating services; 4) language difficulties in tests; and 5) frequent assessment only on formal qualifications, with skills and experience not being evaluated. The 2 basic models for assessing occupational suitability are the valuation of qualifications approach and the valuation of skills approach. To illustrate the operation of various models of assessment, the author discusses these occupations: medicine, nursing, engineering, computing, and electrical trades. The major factors that are essential for an overall strategy of change include 1) less occupational regulation in the labor market; 2) national registration and licensing systems

    2009-07-01

    Pulsed digital holographic interferometry has been used to investigate the plume and the shock wave generated in the ablation process of a Q-switched Nd-YAG ( λ=1064 nm and pulse duration=12 ns) laser pulse on a polycrystalline boron nitride (PCBN) target under atmospheric air pressure. A special setup based on two synchronised wavelengths from the same laser for simultaneous processing and measurement has been used. Digital holograms were recorded for different time delays using collimated laser light ( λ=532 nm) passed through the volume along the target. Numerical data of the integrated refractive index field were calculated and presented as phase maps showing the propagation of the shock wave and the plume generated by the process. Radon inversion has been used to estimate the 3D refractive index fields measured from the projections assuming rotational symmetry. The shock wave density has been calculated using the point explosion model and the shock wave condition equation and its behaviour with time at different power densities ranging from 1.4 to 9.1 GW/cm 2 is presented. Shock front densities have been calculated from the reconstructed refractive index fields using the Gladstone-Dale equation. A comparison of the shock front density calculated from the reconstructed data and that calculated using the point explosion model at different time delays has been done. The comparison shows quite good agreement between the model and the experimental data. Finally the reconstructed refractive index field has been used to estimate the electron number density distribution within the laser-induced plasma. The electron number density behaviour with distance from the target at different power densities and its behaviour with time are shown. The electron number densities are found to be in the order of 10 18 cm -3 and decay at a rate of 3×10 15 electrons/cm 3 ns.

    PubMed

    Tibballs, James

    2006-12-01

    Struan Sutherland (1936-2002) was the doyen of medical research in the field of envenomation and the ultimate authority on the medical management of envenomated victims in Australia for almost 3 decades. In 1981 as Head of Immunology Research of Commonwealth Serum Laboratories (CSL), he produced an antivenom against the Sydney Funnel-web Spider (Atrax robustus)-an accomplishment that had defied numerous previous attempts. Struan also invented the pressure-immobilisation technique of first-aid for snake bite. This ingenious, simple but safe and effective technique revolutionised first-aid management of snake bite and of some other types of envenomation. It made redundant the use of tourniquets and other dangerous first-aid treatments. Similarly, he helped to develop a snake venom detection kit, which enables doctors working at a victim's bedside to ascertain which snake was responsible and which antivenom should be administered. He had a very wide range of research interests and was a prodigious researcher publishing over 200 scientific and medical articles, numerous chapters in books and the standard Australian medical textbook on the management of envenomation, Australian Animal Toxins. He made major contributions to the understanding of the venoms of Australia's remarkable range of fauna including snakes, spiders, Blue-ringed octopus, ants, jellyfish and stinging fish. Struan served the medical fraternity and the public selflessly. He was always available to doctors, or to anybody, to give advice at any hour of the day or night, on management of envenomated victims. Members of the Australian Venom Research Unit, which he founded in 1994 at The University of Melbourne, now continue this 24-h advisory service.

  3. A practical scientific approach to riparian vegetation rehabilitation in Australia.

    Webb, Ashley A; Erskine, Wayne D

    2003-08-01

    The clearance of indigenous riparian vegetation and removal of large woody debris (LWD) from streams combined with the planting of exotic plant species has resulted in widespread detrimental impacts on the fluvial geomorphology and aquatic ecology of Australian rivers. Vegetation exerts a significant influence on fluvial geomorphology by affecting resistance to flow, bank strength, sediment storage, bed stability and stream morphology and is important for aquatic ecosystem function. As the values of indigenous riparian vegetation are becoming better recognised by Australian river managers, large amounts of money and resources are being invested in the planting of indigenous riparian vegetation as part of river rehabilitation programs. This paper summarises the results of an investigation into the survival, growth and regeneration rates of a series of trial native riparian vegetation plantings on in-channel benches in the Hunter Valley of southeastern Australia. The trials were poorly designed for statistical analysis and the paper highlights a number of shortcomings in the methods used. As a result, a new approach to riparian vegetation rehabilitation is outlined that promotes the use of scientific principles and understanding. Appropriate species should be selected using a combination of remnant vegetation surveys, historical records, palynology and field trials. A number of important factors should be considered in the rehabilitation of riparian vegetation to achieve worthwhile results. These include flood disturbance, vegetation zonation, vegetation succession, substrate composition, corridor planting width, planting techniques, native plant regeneration, LWD recruitment and adaptive ecosystem management. This approach, if adopted, revised and improved by river managers, should result in greater success than has been achieved by previous riparian vegetation rehabilitation efforts in Australia.

    Abstract The penicillate genus Unixenus Jones, 1944 is widespread, with species found in Africa, Madagascar, India and Australia. Each of the two Australian species was originally described from single samples from Western Australia. In this study, collections of Penicillata from museums in all states of Australia were examined to provide further details of the two described species, to revise the diagnoses for both the genus and the species, and to better understand the distribution of the two species in Australia. In addition, two new species Unixenus karajinensis sp. n. and Unixenus corticolus sp. n. are described. PMID:22303098

  6. How profitable is methamphetamine dealing in Australia?

    The illicit drug trade is the largest in value among global illicit commodities, at some $320 billion US dollars, according to the UN World Drug Report. Endeavours to control such a large illicit market would be enhanced by improved understanding of the economics of the trade. However, due to its illicit nature many aspects of the illicit drug market are largely unknown. This study explored one economic aspect of illicit drug dealing, profitability, with the aim of developing a better picture of the financial gains from illicit drug dealing. Data were obtained from judges sentencing remarks, key informants from law enforcement, and other published reports which detail the prices paid for methamphetamine in Australia. The financial margins attained from non-crystal methamphetamine dealing in Australia were calculated by examining the best fit for the relationship between prices and quantities: in this case a power law. If it is assumed that a single deal is divided ("cut") between 4 times and 20 times before selling to the next customer, the mark-ups can range from 24% to 59%. The mark-ups appear low compared with those found in US research, but similar to those found in UK research. To our knowledge, this is the first attempt to analyse profitability of methamphetamine dealing in Australia. The findings of this study will help in understanding the motivations and decisions of drug dealers, and potentially assist drug law enforcement agencies to design better strategies to dismantle supply chain linkages which generate excessive profits.

    To describe the characteristics of patients with occupational skin disease (OSD) in a tertiary referral clinic in Victoria, Australia. A retrospective review was conducted of records from patients seen at the Occupational Dermatology Clinic in Melbourne, Australia between 1 January 1993 and 31 December 2010. Of the 2894 people assessed in the clinic during the 18-year period, 44% were women and 56% were men. In all, 2177 (75%) were diagnosed with occupational skin disease (OSD). Of the patients with a work-related skin condition, 45% (n = 979) were considered to be atopic. The most common diagnosis in those with OSD was irritant contact dermatitis (ICD) (44%), followed by allergic contact dermatitis (33%) and endogenous eczema (11%). Women were significantly more likely to have soaps and detergents (P < 0.001) and water/wet work (P < 0.001) as causes of their ICD than men. Men were significantly more likely to have oils and coolants (P < 0.001) and solvent exposures (P < 0.001) as causes of their ICD. Occupational groups with the highest incidence of OSD were the hair and beauty professions (70 per 100 000), followed by machine and plant operators (38 per 100 000) and health-care workers (21 per 100 000). We confirm the importance of occupational contact dermatitis as the most common cause of OSD, with ICD being the most common diagnosis. There are differences in the causes of ICD between our group of male and female workers. For the first time in Australia, rates of OSD in certain industries have been calculated. © 2015 The Australasian College of Dermatologists.

  8. Imaging crustal structure variation across southeastern Australia

    A broad-band seismic network of 28 three-component seismometers was deployed in southeastern Australia to examine variations in crustal thickness across the transition between Precambrian and Phanerozoic lithosphere. Receiver function observations and modelling of P-to-S conversions at the Mohorovičić discontinuity (Moho) have been employed to investigate: (i) the variations in the Moho depth across southeastern Australia, and (ii) the nature of the transition between crust and mantle. Data from temporary deployments were used together with data from the few permanent broad-band stations in the region. The extraction of P-receiver functions from high-quality seismic data recorded on these stations has enabled the determination of the crustal thickness across the region. The crustal thicknesses lie in the range 28-48 km. The Moho depth is generally well correlated with the Earth surface elevation in the southeastern Australia. The Moho estimates from receiver functions are in good agreement with results from reflection profiling. The average crustal thickness is found to be around 39 km beneath the Precambrian area in the west and even thicker beneath the Lachlan Orogen in the east (~ 43 km). The average crustal thickness in between, beneath the Murray Basin is thinner ~ 32 km. Interestingly, the crust in the Mount Gambier volcanic area is rather thick ~ 41 km, suggesting that the limit between the Delamerian and western Lachlan orogens is located east of Mount Gambier. Our results favour a position for the Tasman Line generally consistent with the interpretation by Direen and Crawford (2003) and thus to the east of the location favoured by many authors. The broader crust-mantle transition and thicker crust beneath the Lachlan Orogen suggest the presence of magmatic underplating at the base of the lower crust. The intermediate nature of the crust-mantle transition also suggests magmatic underplating beneath the Gawler Craton and the Curnamona Province.

    Child maltreatment is a complex phenomenon, with four main types (childhood sexual abuse, physical abuse, emotional abuse, and neglect) highly interrelated. All types of maltreatment have been linked to adverse health consequences and exposure to multiple forms of maltreatment increases risk. In Australia to date, only burden attributable to childhood sexual abuse has been estimated. This study synthesized the national evidence and quantified the burden attributable to the four main types of child maltreatment. Meta-analyses, based on quality-effects models, generated pooled prevalence estimates for each maltreatment type. Exposure to child maltreatment was examined as a risk factor for depressive disorders, anxiety disorders and intentional self-harm using counterfactual estimation and comparative risk assessment methods. Adjustments were made for co-occurrence of multiple forms of child maltreatment. Overall, an estimated 23.5% of self-harm, 20.9% of anxiety disorders and 15.7% of depressive disorders burden in males; and 33.0% of self-harm, 30.6% of anxiety disorders and 22.8% of depressive disorders burden in females was attributable to child maltreatment. Child maltreatment was estimated to cause 1.4% (95% uncertainty interval 0.4-2.3%) of all disability-adjusted life years (DALYs) in males, and 2.4% (0.7-4.1%) of all DALYs in females in Australia in 2010. Child maltreatment contributes to a substantial proportion of burden from depressive and anxiety disorders and intentional self-harm in Australia. This study demonstrates the importance of including all forms of child maltreatment as risk factors in future burden of disease studies. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2002-12-01

    Extinction of the Australian megafauna (50ñ5ka) occurred shortly after human colonization (55ñ5ka). A link between the two has been suggested, including the possibility that landscape modification was influential, but pinpointing the role of humans remains elusive. To evaluate changes at the ecosystem level across the extinction event we utilize dietary information recorded by d13C preserved in eggshells of the extant emu (Dromaius novaehollandiae), a large flightless bird. Emus are opportunistic feeders; their diet reflects the range of food sources available in the weeks before nesting (June). d13C quantifies the proportion of C3 vs C4 vegetation that constitutes the emu's diet. A 150,000-year record of emu dietary intact has been reconstructed using more than 300 individuals from Lake Eyre (south-central Australia) dated by 14C, luminescence and/or racemization. Prior to 50 ka emu diet was highly variable, ranging from 100% C3 to 100% C4. However, immediately after 50 ka, emu diet shifted dramatically: the C4 contribution never exceeded 50% (n=200) after 50 ka, whereas more than half the samples older than 50 ka old contain >50% C4 dietary sources. We attribute the observed changes in emu diet to a fundamental rearrangement of the plant ecosystems in semi-arid central Australia. Such a change in plant communities may have contributed to the extinction of many dependent herbivores. The coincidence in time of megafauna extinction and ecosystem collapse shortly after human colonization suggests there may be a causal link. Development of similar records of vegetation change for other regions of Australia are currently underway to evaluate whether the Lake Eyre record reflects a continental scale reorganization of the Australian biota.

    2011-01-01

    This article focuses on the provision and financing of aged care in Australia. Demand for aged care will increase substantially as a result of population aging, with the number of Australians aged 85 and over projected to increase from 400,000 in 2010 to over 1.8 million in 2051. Meeting this demand will greatly strain the current system, and makes it important to exploit opportunities for increased efficiency. A move to greater beneficiary co-payments is also likely, though its extent may depend on whether aged care insurance and other forms of pre-payment can develop. PMID:22312229

    To equip the Chinese VLBI network, a transportable compact active hydrogen maser has been developed at Shanghai Observatory (SO) since 1985. So far five such masers have come into use for VLBI radioastronomy and some military. These hydrogen masers are all compact, relatively light, rugged and easily transportable. In Nov. 1993, one of these masers was transported to Australia Telescope National Facility (ATNF) to determine its performance as a stable oscillator for VLBI. This paper describes the design and construction of the hydrogen maser and presents the results tested at Parkes Observatory of ATNF.

    On July 1, 1990, the first statewide law in Australia requiring wearing of an approved safety helmet by all bicyclists became effective in Victoria (1989 population: approximately 4.3 million) (Figure 1). Implementation of the law was preceded by a decade-long campaign to promote helmet use among the estimated 2.2 million persons who ride bicycles; the campaign included educational programs; mass media publicity; financial incentives; and efforts by professional, community, and bicycle groups (1,2). This report assesses helmet law enforcement, helmet use, and injuries related to bicycling in Victoria.

    The potential therapeutic applications of stem cells are unlimited. However, the ongoing political and social debate surrounding the intellectual property and patenting considerations of stem cell research has led to the implementation of strict legislative regulations. In Australia the patent landscape surrounding stem cells has evolved considerably over the past 20 years. The Australian Patents Act 1990 includes a specific exclusion to the patentability of human beings and of biological processes for their generation. However, this exclusion has received no judicial consideration to date, and so its scope and potential impact on stem cell patents is unclear.

  16. A mammal-like reptile from Australia

    NASA Astrophysics Data System (ADS)

    Thulborn, Richard A.

    1983-05-01

    New fossil evidence indicates that a mammal-like reptile inhabited Australia in the early part of the Triassic period (~220 Myr ago). There are no previous reports of mammal-like reptiles from this continent, and the earliest known Australian mammals have been dated as no older than Oligocene (~23 Myr)1,2. The evidence is an isolated quadrate bone, recently discovered in Lower Triassic rocks of the Arcadia Formation, south-east Queensland. This bone has morphological peculiarities matched only in dicynodonts (mammal-like reptiles of the infraorder Dicynodontia, order Therapsida) and was probably derived from an animal similar or identical to the common African dicynodont Kannemeyeria.

  17. Tuberculosis notifications in Australia, 2012 and 2013.

    2015-06-30

    The National Notifiable Diseases Surveillance System received 1,317 tuberculosis (TB) notifications in 2012 and 1,263 notifications in 2013. This represents a rate of 5.8 per 100,000 population in 2012 and 5.5 per 100,000 population in 2013 and a reversal of the upward trend in TB incidence reported since 2007. In 2012 and 2013, Australia's overseas-born population continued to represent the majority of TB notifications with an incidence rate of 19.5 per 100,000 and 18.4 per 100,000 respectively. The incidence of TB in the Australian-born Indigenous population has fluctuated over the last decade; however, it remained reasonably steady in 2012 and 2013 with an incidence rate of 4.5 per 100,000 and 4.6 per 100,000 respectively. The incidence of TB in the Australian-born non-Indigenous population has continued to remain low at 0.7 per 100,000 in 2012 and 0.8 per 100,000 in 2013. Australia continued to record only a small number of multi-drug resistant TB cases nationally (2012: n=20; 2013: n=22) of which nearly all were identified in the overseas-born population. This report demonstrates excellent and sustained control of TB in Australia and reflects Australia's commitment to reducing the global burden of TB. This work is copyright.

    In Australia, dengue is not endemic, although the vector mosquito Aedes aegypti is established in far north Queensland (FNQ). Aedes albopictus has recently invaded the Torres Strait region, but is not established on mainland Australia. To maintain dengue-free, public health departments in FNQ closely monitor introduced dengue infections and confine outbreaks through rigorous vector control responses. To safeguard mainland Australia from Ae. albopictus establishment, pre-emptive strategies are required to reduce its breeding in difficult to access habitats. We compare the residual efficacy of VectoBac WDG, Bacillus thuringiensis var. israelensis (Bti) formulation, as a residual treatment when misted across a typical FNQ bushland using a backpack mister (Stihl SR 420 Mist Blower) at two dose rates up to 16 m. Semi-field condition results, over 16 weeks, indicate that Bti provided high mortality rates (> 80%) sustained for 11 weeks. Mist application penetrated 16 m of dense bushland without efficacy decline over distance.

    In 2008, Scarlet Alliance, the Australian Sex Workers Association, carried out a needs assessment among sex workers living with HIV in Australia. The research showed that HIV positive sex workers experience discrimination from within the community, are criminalised for sex work and subject to disclosure laws in some states and territories, and face stigma perpetrated by the media. Supported by legislation, they have an almost insurmountable lack of access to policy development due to disclosure and confidentiality issues, and have expressed ongoing frustration at the lack of leadership on the intersecting issues of HIV and sex work. A high profile prosecution of a sex worker living with HIV coincided with the duration of the needs assessment project. The research gave a voice to sex workers living with HIV and highlighted the levels of institutionalised marginalisation and stigmatisation they experience. Criminalisation of sex work, of people living with HIV, and of sex workers living with HIV is at the core of this discrimination and must be challenged. Scarlet Alliance advocates for the decriminalisation of sex work across all jurisdictions in Australia. This will deliver rights to sex workers living with HIV and create a more equitable and productive environment for HIV prevention and public health generally.

    As low carbon-emitting fossil fuel, the natural gas is mainly used for power generation and industrial applications. It is also used for heating and cooling in commercial and residential buildings as well as in transport industry. Although the natural gas reaches the end-user mainly through pipelines (if gas is available locally), the liquefied form is the most viable alternative to transport natural gas from far away location to the end user. The economic progress in Asia and other parts of the world creates huge demand for energy (oil, gas and coal). As low carbon-emitting fuel, the demand for gas especially in liquefied form is progressively rising. Having 7th largest shale gas reserve (437 trillion cubic feet recoverable), Australia has become one of the world's major natural gas producers and exporters and is expected to continue a dominating role in the world gas market in foreseeable future. This paper reviews Australia's current gas reserve, industries, markets and LNG production capabilities.

  9. Medical abortion in Australia: a short history.

    PubMed

    Baird, Barbara

    2015-11-01

    Surgical abortion has been provided liberally in Australia since the early 1970s, mainly in privately owned specialist clinics. The introduction of medical abortion, however, was deliberately obstructed and consequently significantly delayed when compared to similar countries. Mifepristone was approved for commercial import only in 2012 and listed as a government subsidised medicine in 2013. Despite optimism from those who seek to improve women's access to abortion, the increased availability of medical abortion has not yet addressed the disadvantage experienced by poor and non-metropolitan women. After telling the story of medical abortion in Australia, this paper considers the context through which it has become available since 2013. It argues that the integration of medical abortion into primary health care, which would locate abortion provision in new settings and expand women's access, has been constrained by the stigma attached to abortion, overly cautious institutionalised frameworks, and the lack of public health responsibility for abortion services. The paper draws on documentary sources and oral history interviews conducted in 2013 and 2015. Copyright © 2015 Elsevier Inc. All rights reserved.

    Design studies for the offshore pipeline system for the North West Shelf project in Australia commenced in the early 1970s. The trunkline from the North Rankin A platform to shore has recently been completed as the first part of the offshore pipeline system for the North West Shelf project. This pipeline originates from the platform in a water depth of 125 m (410 ft), enters the mouth of Mermaid Sound, and terminates just south of Withnell Bay on the Burrup Peninsula, on the North West coastline of Western Australia. The pipeline is 1,016 mm (40 in.) in diameter and 134.2 km (83.4 miles) long. It will operate in two-phase flow, bringing both gas and condensate to an onshore plant near its landfall. A slugcatcher has been constructed within the plant to receive liquidhydrocarbon slugs from the pipeline. The trunkline to shore will initially serve only the one offshore platform and operate at about 25% of its capacity to supply the Western Australian domestic gas market. The domestic gas plant on the Burrup Peninsula is being constructed by Woodside to produce pipeline-quality gas for delivery to the State Energy Commission and condensate for shipment by coastal tankers.

  11. The funding of private hospitals in Australia.

    Bloom, Abby L

    2002-01-01

    Private hospitals are an essential component of Australia's complex mix of public and private health funding and provision. Private hospitals account for 34.3 per cent of all hospital separations, and over half (56.2%) of all same-day separations. The revenue (funding) of the sector approached $4 billion by 1998/99, and as a result of its recent rapid growth capital expenditure in the sector was nearly $550 million in the same year. Private casemix of private hospitals is distinctive, and characterised by a high proportion of surgical procedures in general (48.1 per cent), and more than a majority of all services in such areas as rehabilitation, orthopaedics (shoulder, knee, spinal fusion, and hand surgery), alcohol disorders, same day colonoscopy and sleep disorders. This chapter synthesizes data from a multitude of sources to produce a comprehensive picture of Australia's private hospital sector and its funding. It examines the funding (revenue) sources of private hospitals, and considers how and why private hospitals approach the issue of funding from a different perspective than their public sector colleagues. To illustrate how Australian private hospitals approach revenue (funding) strategically, a series of indicative types of hospitals is explored.

    Neutron capture therapy research in Australia has continued to grow since the first Australia-Japan workshop in April, 1986. The support base has broadened and the wide range of contributing laboratories includes universities, research institutes, and hospitals. Considerable progress has been made in boron chemistry--an accurate boron assay technique has been developed, boron analogues of chlorpromazine and thiouracil have been synthesised or nearly so, and decaborane conjugation with monoclonal antibodies has been achieved to the required loadings. In vitro cell survival experiments are proceeding in the Moata reactor using human melanoma and mouse cell lines incubated with enriched boronophenylalanine and boron tetraphenyl porphyrins. Electron microscopy examination of radiation damaged morphology shows considerable differences between cell lines. Progress with the nude mouse human melanoma model has been slow because of the lack of a reliable in vivo melanotic melanoma line, and the B16 mouse line is found to be more efficacious. Tailored beam calculations for the 10 MW HIFAR reactor indicate the difficulty of obtaining a suitable therapeutic beam because of the generated gamma dose in the beam filters. A new approach to NCT utilises the enormous cross section of 157Gd and the induced-Auger effect which has been shown to cause double strand breaks in circular DNA. 34 references.

  13. 'Linkage' pharmaceutical evergreening in Canada and Australia.

    PubMed

    Faunce, Thomas A; Lexchin, Joel

    2007-06-01

    'Evergreening' is not a formal concept of patent law. It is best understood as a social idea used to refer to the myriad ways in which pharmaceutical patent owners utilise the law and related regulatory processes to extend their high rent-earning intellectual monopoly privileges, particularly over highly profitable (either in total sales volume or price per unit) 'blockbuster' drugs. Thus, while the courts are an instrument frequently used by pharmaceutical brand name manufacturers to prolong their patent royalties, 'evergreening' is rarely mentioned explicitly by judges in patent protection cases. The term usually refers to threats made to competitors about a brand-name manufacturer's tactical use of pharmaceutical patents (including over uses, delivery systems and even packaging), not to extension of any particular patent over an active product ingredient. This article focuses in particular on the 'evergreening' potential of so-called 'linkage' provisions, imposed on the regulatory (safety, quality and efficacy) approval systems for generic pharmaceuticals of Canada and Australia, by specific articles in trade agreements with the US. These 'linkage' provisions have also recently appeared in the Korea-US Free Trade Agreement (KORUSFTA). They require such drug regulators to facilitate notification of, or even prevent, any potential patent infringement by a generic pharmaceutical manufacturer. This article explores the regulatory lessons to be learnt from Canada's and Australia's shared experience in terms of minimizing potential adverse impacts of such 'linkage evergreening' provisions on drug costs and thereby potentially on citizen's access to affordable, essential medicines.

    Alcohol has been consumed in Australia since European settlement in 1788. In 1998, approximately 60% of Australians consumed an alcoholic beverage at least once per week. The effects of alcohol on the human body are dose dependent, where the harmful effects of alcohol are generally observed only when alcohol consumption exceeds moderate consumption levels of 30 to 40 g of alcohol per day. The discovery that a J-shaped curve described the relationship between level of alcohol consumption and risk of cardiovascular disease was, however, only made in 1990-cardiovascular disease is the leading cause of death in the western world. Thus prior to 1990, Australian public health policy focused primarily on the harmful effects of alcohol consumption and the health benefits of a moderate level of alcohol consumption have only recently been recognized in public policy. This paper chronicles changes in Australian Federal government policy on alcohol since the initial draft National health policy on alcohol in Australia was presented to the Ministerial Council on Drug Strategy in 1987 to the National Drug Strategic plan for action 2001 to 2003-2004 which was launched in July last year.

  16. Cosmetic surgery in Australia: a risky business?

    PubMed

    Parker, Rhian

    2007-08-01

    Cosmetic surgery is increasing in popularity in Australia and New Zealand, as it is across other Western countries. However, there is no systematic mechanism for gathering data about cosmetic surgery, nor about the outcomes of that surgery. This column argues that the business of cosmetic surgery in Australia has questionable marketing standards, is conducted with little scrutiny or accountability and offers patients imperfect knowledge about cosmetic procedures. It also argues that while medical practitioners debate among themselves over who should carry out cosmetic procedures, little attention has been paid to questionable advertising in the industry and even less to highlighting the real risks of undergoing cosmetic surgery. While consumers are led to believe that cosmetic surgery is accessible, affordable and safe, they are sheltered from the reality of invasive and risky surgery and from the ability to clearly discern that all cosmetic procedures carry risk. While doctors continue to undertake advertising and engage in a territorial war, they fail to address the really important issues in cosmetic surgery. These are: providing real evidence about what happens in the industry, developing stringent regulations under which the industry should operate and ensuring that all patients considering cosmetic surgery are fully informed as to the risks of that surgery.

    2001-01-01

    Domestic wastewater reuse is currently not permitted anywhere in Australia but is widely supported by the community, promoted by researchers, and improvised by up to 20% of householders. Its widespread implementation will make an enormous contribution to the sustainability of water resources. Integrated with other strategies in the outdoor living environment of settlements in arid lands, great benefit will be derived. This paper describes six options for wastewater reuse under research by the Remote Area Developments Group (RADG) at Murdoch University and case studies are given where productive use is being made for revegetation and food production strategies at household and community scales. Pollution control techniques, public health precautions and maintenance requirements are described. The special case of remote Aboriginal communities is explained where prototype systems have been installed by RADG to generate windbreaks and orchards. New Australian design standards and draft guidelines for domestic greywater reuse produced by the Western Australian State government agencies for mainstream communities are evaluated. It is recommended that dry composting toilets be coupled with domestic greywater reuse and the various types available in Australia are described. For situations where only the flushing toilet will suffice the unique 'wet composting' system can be used and this also is described. A vision for household and community-scale on-site application is presented.

    Melioidosis, an infection due to the environmental bacterium Burkholderia pseudomallei, is endemic to Southeast Asia and northern Australia, with cases strongly correlated with the monsoonal wet season. We hypothesized that seasonal variation in the mode of acquisition, informed by traditional knowledge, would result in variations in disease characteristics as well as disease incidence. We explored the seasonal variation in acute, culture-confirmed melioidosis using local Aboriginal definitions of seasons in presentations to the Royal Darwin Hospital, the referral centre for the Top End of the Northern Territory, Australia. In 387 patients, we observed an increased proportion of patients with pneumonia (60%) and severe sepsis (25%) associated with presentations in the wet seasons Gunumeleng (October-December) and Gudjewg (January-March) compared with the drier seasons Wurrgeng (June August) and Gurrung (August-October) (pneumonia 26%, severe sepsis 13%). This observation supports the hypothesis that in the wet seasons there may be changes in the mode and/or magnitude of exposure to B. pseudomallei, with a shift from percutaneous inoculation to aerosol inhalation, for instance.

    South Australia occupies the center of the Australian continent. The deserts of the interior give way to more fertile land along the coast of the Southern Ocean. This true-color MODIS image from September 17, 2001, shows the marked contrast between the country's arid interior--where seasonal salt lakes stand out in white against the deserts' vast, red expanse--and the coastal regions, including Spencer Gulf, to the lower left of the image's center. The characteristic blue-green swirls of a phytoplankton bloom can be seen in the Gulf and southeastward along the coast. To Spencer Gulf's east, the brownish-gray pixels on the eastern coast of the Gulf of St. Vincent indicate the location of the city of Adelaide, the region's capital. The large dark areas that stand out amid the green vegetation do not indicate areas where vegetation had been damaged or burned. In fact, the opposite is actually true. In many cases, those areas are land protected by national and state parks and preserves, where the natural vegetation of the semi-arid landscape is allowed to exist undisturbed. For example, due east of Adelaide are Billiat Conservation Park and the semi-rectangular Murray Sunset National Park, which is across the border from South Australia in Victoria. South of those parks are the parks of the Big Desert (top) and Little Desert (bottom).

    2016-12-01

    Seismic attenuation is a valuable observation that can provide insight into lithospheric structure complementary to the more commonly studied seismic velocity. We map apparent attenuation beneath the Australian mainland and Tasmania using 21 deep-focus teleseismic events recorded on Geoscience Australia's seismic network. In contrast to the traditional frequency-domain approach, we use a time-domain based procedure. For each event, we estimate a source waveform from the highest quality recordings, apply an attenuation operator to the source estimate using a range of t* values to find the best fit to the record at each station, and invert the ensemble of t* estimates to produce a smooth map. Our results are broadly consistent with velocity models obtained from surface-wave tomography. Lowest apparent attenuation occurs in the Northern Territory near Darwin, with low attenuation appearing to extend down to the Southern Territory's southern coast. The Archean Gawler, Pilbara and Yilgarn cratons also correspond to regions of lower attenuation. New South Wales and Victoria are primarily dominated by high attenuation values, with the highest apparent attenuation occurring in Tasmania, possibly associated with the East Australia Plume System.

    2015-01-01

    This paper aims to explore and discuss the role that ANMAC and the accreditation standards play in pre-registration nursing education nationally. The context of the discussion is situated in the continuum of events that mark the accreditation of nursing education in Australia. The National Registration and Accreditation Scheme has given rise to significant challenges related to the accreditation of nursing programs of education in Australia. Given the importance of accreditation to the quality of nursing education, ANMAC in its appointed role as accrediting authority, must fill the position rather than occupy it. Enhancing transparency and effectiveness is central to ensuring accreditation facilitates quality in nursing education. Given ANMAC's key position, further work is needed in developing a broad base of expertise by fostering scholarly output in the substantive area of nursing accreditation. There is a concerning lack of research centred on the accreditation of programs of nursing education along with the processes associated with it. This problem is not restricted to the Australian context but also extends internationally. In this context, the expertise of accreditors ought to be questioned along with the processes ANMAC use to identify individual capability. As such, the selection of experts needs to be articulated clearly by ANMAC along with the ownership of introducing a research culture into accreditation.

    2013-01-01

    Saproscincus skinks are restricted to wet forest habitats of eastern Australia. Eleven species have previously been described, with most having small distributions in disjunct areas of subtropical and tropical rainforest. The localized distributions and specific habitat requirements of Saproscincus have made them a key group for understanding the biogeographic history of Australia's rainforests. Here I describe a new species of Saproscincus from the Melville Range on Cape Melville, north-east Australia. The Melville Range is composed of boulder-fields and areas of rainforest in the uplands, and is highly isolated from other areas of elevated rainforest. All individuals of the new species were found on a moist ridgeline, active on boulders under a rainforest canopy or on boulder-field immediately adjacent to rainforest. Saproscincus saltus sp. nov. is highly distinct in morphology and colour pattern. Of particular interest are its long limbs and digits compared to congeners, which in conjunction with the observed ecology, suggest a long history of association with rock. The discovery of S. saltus sp. nov. extends the distribution of the genus over 100 km north from the nearest congeners in the Wet Tropics region. This species brings the number of vertebrates known to be endemic to the Melville Range to six, which is remarkable for such a small area.

    The biogenic emissions of isoprene and monoterpenes are one of the main drivers of atmospheric photochemistry, including oxidant and secondary organic aerosol production. In this paper, the emission rates of isoprene and monoterpenes from Australian vegetation are investigated for the first time using the Model of Emissions of Gases and Aerosols from Nature version 2.1 (MEGANv2.1); the CSIRO chemical transport model; and atmospheric observations of isoprene, monoterpenes and isoprene oxidation products (methacrolein and methyl vinyl ketone). Observations from four field campaigns during three different seasons are used, covering urban, coastal suburban and inland forest areas. The observed concentrations of isoprene and monoterpenes were of a broadly similar magnitude, which may indicate that southeast Australia holds an unusual position where neither chemical species dominates. The model results overestimate the observed atmospheric concentrations of isoprene (up to a factor of 6) and underestimate the monoterpene concentrations (up to a factor of 4). This may occur because the emission rates currently used in MEGANv2.1 for Australia are drawn mainly from young eucalypt trees (< 7 years), which may emit more isoprene than adult trees. There is no single increase/decrease factor for the emissions which suits all seasons and conditions studied. There is a need for further field measurements of in situ isoprene and monoterpene emission fluxes in Australia.

    A new focus of scrub typhus (Rickettsia tsutsugamushi) is described in a remote rain forest region of the Northern Territory of Australia. Five serologically confirmed cases, two near fatal with multisystem involvement, have occurred since the area became accessible to tourists. As tourism increases, other remote foci of vectors and organisms may also be recognized in tropical Australia.

  14. New cryptic species of Teratosphaeria on Eucalyptus in Australia.

    PubMed

    Andjic, Vera; Maxwell, Aaron; Hardy, Giles E StJ; Burgess, Treena I

    2016-12-01

    Teratosphaeria destructans and T. viscida are serious pathogens causing leaf, bud and shoot blight diseases of Eucalyptus plantations in the subtropics and tropics of South-East Asia (T. destructans) and North Queensland, Australia (T. viscida). During disease surveys in northern Western Australia and the Northern Territory of Australia, symptoms resembling those of T. destructans were observed on young and adult leaves of native and plantation Eucalyptus spp. and its hybrids. Phylogenetic studies revealed Teratosphaeria species associated with these symptoms are new taxonomic novelties described here as T. novaehollandiae and T. tiwiana spp. nov. Isolates from previous records of T. destructans recorded in Australia were re-examined and based upon the phylogenetic evidence are reassigned to these new taxa. We conclude that T. destructans is absent from Australia.

    depositional textures are well preserved and show little evidence of recrystallization and diagenetic reorganization. Only small percentages of Neoproterozoic dolomites of Zagros and central Iran are synsedimentary or formed during early diagemesis. Most dolomites are medium to coarsely crystalline, due to an increased amount of diagenetic alteration. Geochemical evidence also confirms that dolomicrites are the least-altered dolomites in Gachin, Zagros, Iran. These dolomicrites have high values of Mg, low values of Fe and Mn, high values of Sr and Na and heavy δ18O values and fall within the cold water dolomite fields of Renison, and least-altered Neoproterozoic dolomite of California. This dolomite probably formed in cold water conditions, which corresponds to the cold climatic condition during Neoproterozoic. Geochemical evidence also confirms that dolomicrites are the least-altered dolomites. These dolomicrites have high values of Mg, low values of Fe and Mn, high values of Sr and Na and heavy δ18O values and fall within the cold water dolomite fields of Renison, and least-altered Neoproterozoic dolomite of California. These dolomite probably formed in cold water conditions, which corresponds to the cold climatic condition during Neoproterozoic. However, the absence of tillite, diamictite and the lack of dropstones or glacial erratics in carbonate sequences indicate that climatic conditions in Iran was not as cold as other parts of the world, such as Australia or USA during Neoproterozoic and Gaskiers glacial period (~580 Ma) was not active in Iran. The heaviest δ18O values (-0.61‰) in Gachin least-altered dolomicrite correspond to paleotemperature of about 18°C (Land equation). Cold water marine dolomite from other geologic periods, such as Barremian -age sediments with temperatures as low as 15°C, and from the West Florida Neogen cold deep water marine dolomite with palaeotemperature of 4.5 to 12°C, have been reported recently (Flood and Chivas, 1995).

  16. Growth dynamics of Australia's polar dinosaurs.

    Woodward, Holly N; Rich, Thomas H; Chinsamy, Anusuya; Vickers-Rich, Patricia

    2011-01-01

    Analysis of bone microstructure in ornithopod and theropod dinosaurs from Victoria, Australia, documents ontogenetic changes, providing insight into the dinosaurs' successful habitation of Cretaceous Antarctic environments. Woven-fibered bone tissue in the smallest specimens indicates rapid growth rates during early ontogeny. Later ontogeny is marked by parallel-fibered tissue, suggesting reduced growth rates approaching skeletal maturity. Bone microstructure similarities between the ornithopods and theropods, including the presence of LAGs in each group, suggest there is no osteohistologic evidence supporting the hypothesis that polar theropods hibernated seasonally. Results instead suggest high-latitude dinosaurs had growth trajectories similar to their lower-latitude relatives and thus, rapid early ontogenetic growth and the cyclical suspensions of growth inherent in the theropod and ornithopod lineages enabled them to successfully exploit polar regions.

  18. Australia, Shaded Relief and Colored Height

    NASA Technical Reports Server (NTRS)

    2004-01-01

    Australia is the world's smallest, flattest, and (after Antarctica) driest continent, but at 7.7 million square kilometers (3.0 million square miles) it is also the sixth largest country. Its low average elevation (300 meters, or less than 1000 feet) is caused by its position near the center of a tectonic plate, where there are no volcanic or other geologic forces of the type that raise the topography of other continents. In fact Australia is the only continent without any current volcanic activity at all - the last eruption took place 1400 years ago at Mt. Gambier.

    The Australian continent is also one of the oldest land masses, with some of its erosion-exposed bedrock age dated at more than 3 billion years. More than one-fifth of the land area is desert, with more than two-thirds being classified as arid or semi-arid and unsuitable for settlement. The coldest regions are in the highlands and tablelands of Tasmania and the Australian Alps at the southeastern corner of the continent, location of Australia's highest point, Mt. Kosciusko (2228 meters, or 7310 feet.)

    Prominent features of Australia include the Lake Eyre basin, the darker green region visible in the center-right. At 16 meters (52 feet) below sea level this depression is one of the largest inland drainage systems in the world, covering more than 1.3 million square kilometers (500,000 square miles). The mountain range near the east coast is called the Great Dividing Range, forming a watershed between east and west flowing rivers. Erosion has created deep valleys, gorges and waterfalls in this range where rivers tumble over escarpments on their way to the sea.

    The crescent shaped uniform green region in the south, just left of center, is the Nullarbor Plain, a low-lying limestone plateau which is so flat that the Trans-Australian Railway runs through it in a straight line for more than 483 kilometers (300 miles).

    Two of the offshore areas recently released for exploration bids by the Australian government are NT94-1 and NT94-2 covering 23,000 sq km in the oil producing Bonaparte basin off northwestern Australia 300 km northwest of Darwin. Three wells have been drilled in the two areas, including Evans Shoal-1 which made a gas discovery currently considered to be non-commercial. The results of a study by the Australian Bureau of Resource Sciences (BRS) have been synthesized into the Evans Shoal Area Bulletin and Data Base. BRS interprets the available geochemical and maturation data to indicate that potential source rocks are present in the Jurassic Plover formation and Flamingo group and the Cretaceous Bathurst Island group. The paper describes the area geology, play types, and gas and oil potential.

  20. Fit for purpose: Australia's National Fitness Campaign.

    2011-12-19

    During a time of war, the federal government passed the National Fitness Act 1941 to improve the fitness of the youth of Australia and better prepare them for roles in the armed services and industry. Implementation of the National Fitness Act made federal funds available at a local level through state-based national fitness councils, which coordinated promotional campaigns, programs, education and infrastructure for physical fitness, with volunteers undertaking most of the work. Specifically focused on children and youth, national fitness councils supported the provision of children's playgrounds, youth clubs and school camping programs, as well as the development of physical education in schools and its teaching and research in universities. By the time the Act was repealed in 1994, fitness had become associated with leisure and recreation rather than being seen as equipping people for everyday life and work. The emergence of the Australian National Preventive Health Agency Act 2010 offers the opportunity to reflect on synergies with its historic precedent.
