A Method For Improving Landscape Scale Temperature Predictions And The Implications For Vegetation Modelling, Michael B. Ashcroft Jan 2006

A Method For Improving Landscape Scale Temperature Predictions And The Implications For Vegetation Modelling, Michael B. Ashcroft

Faculty of Science, Medicine and Health - Papers: part A

Understanding how environmental factors influence the spatial distribution of vegetation allows environmental managers to plan for issues such as climate change, ecological restoration and intensified land use. Elevation is often used as an indirect predictor of temperature, but this limits the applicability of environmental models to other study areas and introduces errors in mountainous terrain where variations in slope, aspect, and radiation can significantly alter the relationship between elevation and temperature. Some studies have developed estimates for temperature that also consider factors such as radiation, but these usually estimate the temperature for each location without considering the surrounding environment. In ...

Fatality After Deliberate Ingestion Of Sustained-Release Ibuprofen: A Case Report, David Wood, Jane Monaghan, Peter Streete, Alison L. Jones, Paul Dargan Jan 2006

Fatality After Deliberate Ingestion Of Sustained-Release Ibuprofen: A Case Report, David Wood, Jane Monaghan, Peter Streete, Alison L. Jones, Paul Dargan

Faculty of Science, Medicine and Health - Papers: part A

Introduction Ibuprofen is a nonsteroidal anti-inflammatory drug available over the counter and on prescription for the management of pain and inflammation. Severe toxicity is rare following deliberate self-poisoning with ibuprofen, and patients are usually either asymptomatic or develop only mild gastrointestinal toxicity. Although there have been nine other reported fatalities, co-existent factors have probably contributed to all of these deaths. We report here a fatality from isolated toxicity following self-poisoning with sustained-release ibuprofen. Case report A 26-year-old female presented after deliberate ingestion of up to 105 g sustained-release ibuprofen, with a reduced level of consciousness, severe metabolic acidosis and haemodynamic ...

Lincosamide antibiotics include lincomycin, a compound produced by several actinomycetes, and its semisynthetic chlorinated derivative clindamycin. These antibiotics block the peptidyltransferase activity of the 50S subunit of the bacterial ribosome, inhibiting protein synthesis, and are active against most gram-positive cocci and anaerobes. However, they are not generally effective against gram-negative bacilli due to intrinsic resistance.

Impact Of Transatlantic Transport Episodes On Summertime Ozone In Europe, G Guerova, I Bey, J Attie, R Martin, J Cui, M Sprenger

Faculty of Science, Medicine and Health - Papers: part A

This paper reports on the transport of ozone (O3) and related species over the North Atlantic ocean and its impact on Europe. Measurements of nitrogen dioxide (NO2) and carbon monoxide (CO) columns from the GOME and MOPITT satellite instruments, respectively, are used in conjunction with the GEOS-CHEM global model of transport and tropospheric chemistry to identify the major events of long range transport that reach Europe over the course of summer 2000. Sensitivity model simulations are used to analyse observed O3 distributions with respect to the impact of long range transport events. For that purpose, we used ...


Calculation Of The Cosmogenic Nuclide Production Topographic Shielding Scaling Factor For Large Areas Using Dems, Alexandru T. Codilean Jan 2006

Calculation Of The Cosmogenic Nuclide Production Topographic Shielding Scaling Factor For Large Areas Using Dems, Alexandru T. Codilean

Faculty of Science, Medicine and Health - Papers: part A

The recent surge of applications using terrestrial cosmogenic nuclides (TCNs) to calculate catchment-averaged erosion rates from isotopic concentrations in fluvial sediment, and the prospect of coupling TCN production functions with numerical surface process models (SPMs), necessitate a fast and accurate algorithm for the calculation of topographic shielding. Topographic shielding refers to the proportion of the incoming cosmic radiation that is shielded by the surrounding topography, the scaling factor being defined as the ratio of the unshielded (total minus shielded) to the total (or maximum) cosmic ray flux (i.e. the flux received by a horizontal, unobstructed surface). Topography contributes to ...


Surface Process Models And The Links Between Tectonics And Topography, Alexandru T. Codilean, Paul Bishop, Trevor B. Hoey Jan 2006

Surface Process Models And The Links Between Tectonics And Topography, Alexandru T. Codilean, Paul Bishop, Trevor B. Hoey

Faculty of Science, Medicine and Health - Papers: part A

Advances in the theoretical understanding of large-scale tectonic and surface processes, along with a rapid growth of computing technology, have stimulated interest in the use of numerical surface process models (SPMs) of long-term landscape evolution, especially in relation to the links between tectonics and topography. Because of these advances and possibilities and because SPMs continue to play an important part in recent geological, geomorphological, thermochronological and other geosciences research, the models warrant review and assessment. This review summarizes and evaluates the important issues concerning SPMs of long-term landscape evolution that have been addressed only in a passing way by previous ...

Background: Integrons are genetic elements capable of the acquisition, rearrangement and expression of genes contained in gene cassettes. Gene cassettes generally consist of a promoterless gene associated with a recombination site known as a 59-base element (59-be). Multiple insertion events can lead to the assembly of large integron-associated cassette arrays. The most striking examples are found in Vibrio, where such cassette arrays are widespread and can range from 30 kb to 150 kb. Besides those found in completely sequenced genomes, no such array has yet been recovered in its entirety. We describe an approach to systematically isolate, sequence and annotate ...

Faculty of Science, Medicine and Health - Papers: part A

We have printed arrays of strain sensors on textiles by inkjet printing of conducting lines and piezoresistive polymer (PEDOT) in order to provide detailed information about the response of a fabric in use. Conducting polymer has been printed onto polyamide and cellulose woven fabrics to form sensors using a modified HP inkjet print-head and X-Y linear positioning table. Good penetration and attachment is found on mercerized cotton but not on polyamide. Silver nitrate lines have been printed onto polyamide and converted to silver connectors by electroless plating. We observed that resistance of silver lines ranged from 0.7-1.5Ω/cm ...

The catalytic core of Escherichia coli DNA polymerase III contains three tightly associated subunits, the α, ε, and θ subunits. The θ subunit is the smallest and least understood subunit. The three-dimensional structure of θ in a complex with the unlabeled N-terminal domain of the ε subunit, ε186, was determined by multidimensional nuclear magnetic resonance spectroscopy. The structure was refined using pseudocontact shifts that resulted from inserting a lanthanide ion (Dy3+, Er3+, or Ho3+) at the active site of ε186. The structure determination revealed a three-helix bundle fold that is similar to the solution structures of θ ...

The Impact Of Institutional Surveillance Technologies On Student Behaviour, Shane Dawson

Faculty of Science, Medicine and Health - Papers: part A

Contemporary education institutions are increasingly investing fiscal and human resources to further develop their online infrastructure in order to enhance flexible learning options and the overall student learning experience. Coinciding with the implementation of these technologies has been the centralisation of data and the emergence of online activities that have afforded the capacity for more intimate modes of surveillance by both the institution and education practitioner. This study offers an initial investigation into the impact of such modes of surveillance on student behaviours. Both internal and external students surveyed indicated that their browsing behaviours, the range of topics discussed and ...

Beyond The Rhetoric: What Do We Mean By A 'Model Of Care'?, Patricia Davidson, Elizabeth Halcomb, L Hickman, J Phillips, B Graham

Faculty of Science, Medicine and Health - Papers: part A

Background: Contemporary health care systems are constantly challenged to revise traditional methods of health care delivery. These challenges are multifaceted and stem from: (1) novel pharmacological and non-pharmacological treatments; (2) changes in consumer demands and expectations; (3) fiscal and resource constraints; (4) changes in societal demographics in particular the ageing of society; (5) an increasing burden of chronic disease; (6) documentation of limitations in traditional health care delivery; (7) increased emphasis on transparency, accountability, evidence-based practice (EBP) and clinical governance structures; and (8) the increasing cultural diversity of the community. These challenges provoke discussion of potential alternative models of care ...

Measles is uncommon in Australia due to effective national vaccination strategies. In mid-2003, a cluster of nine cases of measles occurred in western Sydney. The index case was a 29-year-old traveller recently returned from Nepal. The case presented to hospital and transmitted the disease to two others in the Emergency Department. Further cases resulted from both community and nosocomial transmission. The median age of cases was 24 years, with three cases in children aged under four years. Only one person had a documented history of measles vaccination, a child who had received one dose of vaccine overseas. One case was ...

Faculty of Science, Medicine and Health - Papers: part A

The randomly amplified polymorphic DNA technique was used to trace the geographic origin of Liposcelis bostrychophila Badonnel populations in Australia from unknown geographic sources internationally. Haplotype (or clonal) diversity was high, with 474 unique haplotypes found from 616 individuals genotyped. Gene diversity estimates (0.10–0.28) and percent polymorphic loci (38.1–88.1%) were moderate to high for most populations. This resulted in genetic distance estimates that ranged from 0.04 to 0.26 and were significantly different for most pairwise population combinations. G ST values for all populations were also moderate (0.04–0.54) and again ...


A Holistic Approach To Aboriginal Well Health Screening, Jill Mitchell, Kathryn Weston Jan 2006

A Holistic Approach To Aboriginal Well Health Screening, Jill Mitchell, Kathryn Weston

Faculty of Science, Medicine and Health - Papers: part A

Moving past crisis management to the implementation of effective primary health care programs is key to rapid improvement in Aboriginal health. Historically. service delivery has been based on a sickness and disease model rather than an approach that focuses towards well health. Well health incorporates disease prevention. early intervention and management to restore physical and mental health, together with social health and wellbeing. Social health and wellbeing are crucial components of the holistic approach required to address the determinants of health, socio-ilconomic disadvantage and continuing grief which are evident in many remote Aboriginal communities.


Observation Of Nondegenerate Cavity Modes For A Distorted Cavity Modes For A Distorted Polystyrene Microsphere, Adam J. Trevitt, Philip J. Wearne, Evan J. Bieske, Michael D. Schuder Jan 2006

Observation Of Nondegenerate Cavity Modes For A Distorted Cavity Modes For A Distorted Polystyrene Microsphere, Adam J. Trevitt, Philip J. Wearne, Evan J. Bieske, Michael D. Schuder

Nondegenerate azimuthal morphology-dependent resonances are observed for a distorted, fluorescently labeled polystyrene microsphere levitated in a quadrupole ion trap. Modeling the individual resonances by using perturbation theory allows a determination of quadrupole and octupole distortion parameters. The particle’s shape changes slowly over the course of the measurement and eventually becomes spherical. The morphological changes are facilitated by laser heating of the particle above the polystyrene glass transition temperature. We demonstrate a method of transforming a trapped particle to a sphere and rendering its azimuthal modes degenerate.
