Earth Is (Mostly) Flat: Apportionment Of The Flux Of Continental Sediment Over Millennial Time Scales, Jane K. Willenbring, Alexandru T. Codilean, Brandon Mcelroy Dec 2012

Earth Is (Mostly) Flat: Apportionment Of The Flux Of Continental Sediment Over Millennial Time Scales, Jane K. Willenbring, Alexandru T. Codilean, Brandon Mcelroy

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

We use a new compilation of global denudation estimates from cosmogenic nuclides to calculate the apportionment and the sum of all sediment produced on Earth by extrapolation of a statistically significant correlation between denudation rates and basin slopes to watersheds without denudation rate data. This robust relationship can explain approximately half of the variance in denudation from quartz-bearing topography drained by rivers using only mean slopes as the predictive tool and matches a similar fit for large river basins. At slopes >200 m/km, topography controls denudation rates. Controls on denudation in landscapes where average slopes are 10 mm/k ...


High Muscle Mitochondrial Volume And Aerobic Capacity In A Small Marsupial (Sminthopsis Crassicaudata) Reveals Flexible Links Between Energy-Use Levels In Mammals, Terence Dawson, Koa Webster, Enhua Lee, William A. Buttemer Dec 2012

High Muscle Mitochondrial Volume And Aerobic Capacity In A Small Marsupial (Sminthopsis Crassicaudata) Reveals Flexible Links Between Energy-Use Levels In Mammals, Terence Dawson, Koa Webster, Enhua Lee, William A. Buttemer

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

We investigated the muscle structure–function relationships that underlie the aerobic capacity of an insectivorous, small (~15 g) marsupial, Sminthopsis crassicaudata (Family: Dasyuridae), to obtain further insight into energy use patterns in marsupials relative to those in placentals, their sister clade within the Theria (advanced mammals). Disparate hopping marsupials (Suborder Macropodiformes), a kangaroo (Macropus rufus) and a rat-kangaroo (Bettongia penicillata), show aerobic capabilities as high as those of ‘athletic’ placentals. Equivalent muscle mitochondrial volumes and cardiovascular features support these capabilities. We examined S. crassicaudata to determine whether highly developed aerobic capabilities occur elsewhere in marsupials, rather than being restricted to ...


2-Cyanoethyl N,N,N',N'-Tetraisopropylphosphorodiamidite, Jichao Zhang Dec 2012

2-Cyanoethyl N,N,N',N'-Tetraisopropylphosphorodiamidite, Jichao Zhang

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

2-Cyanoethyl N,N,N′,N′-tetraisopropylphosphorodiamidite is a colorless viscous liquid, which is soluble in most organic solvents. It is a widely used phosphitylating reagent for the preparation of various phosphorylated biomolecules, such as nucleoside carbohydrate conjugates, phospholipids and glycopeptides. In particular, this reagent is highly effective for automated solid-phase DNA/RNA oligonucleotide synthesis. 2-Cyanoethyl N,N,N′,N′-tetraisopropylphosphorodiamidite has shown great utility in the coupling of nucleobases or carbohydrates via their phosphotriesters in the presence of activators such as 1H-tetrazole, in moderate yields under mild conditions. Additionally, 2-cyanoethyl N,N,N′,N′-tetraisopropylphosphorodiamidite is cheaper and more stable ...


Automated Surface Sampling Of Lipids From Worn Contact Lenses Coupled With Tandem Mass Spectrometry, Simon H. Brown, Liam H. Huxtable, Mark D. P Willcox, Stephen J. Blanksby, Todd W. Mitchell Nov 2012

Automated Surface Sampling Of Lipids From Worn Contact Lenses Coupled With Tandem Mass Spectrometry, Simon H. Brown, Liam H. Huxtable, Mark D. P Willcox, Stephen J. Blanksby, Todd W. Mitchell

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

The deposition of biological material (biofouling) onto polymeric contact lenses is thought to be a major contributor to lens discomfort and hence discontinuation of wear. We describe a method to characterize lipid deposits directly from worn contact lenses utilizing liquid extraction surface analysis coupled to tandem mass spectrometry (LESA-MS/MS). This technique effected facile and reproducible extraction of lipids from the contact lens surfaces and identified lipid molecular species representing all major classes present in human tear film. Our data show that LESA-MS/MS is a rapid and comprehensive technique for the characterization of lipid-related biofouling on polymer surfaces.

Mechanism Of Secondary Currents In Open Channel Flows, Shu-Qing Yang, Soon Keat Tan, Xi-Kun Wang Oct 2012

Mechanism Of Secondary Currents In Open Channel Flows, Shu-Qing Yang, Soon Keat Tan, Xi-Kun Wang

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

This paper describes the conditions for initiation and maintenance of secondary currents in open channel flows. By analyzing the Reynolds equation in the wall-normal and wall-tangent directions, this study reveals that, like other types of vortices, the secondary currents are originated in the near-boundary region, and the magnitude (or strength) of secondary flow is proportional to the lateral gradient of near-wall velocity. The near-wall secondary flow always moves from the region with lower velocity (or lower boundary shear stress) to the location with higher velocity (or higher boundary shear stress). Subsequently, the near-boundary secondary flow creeps into the main flow ...

Dietary Intake Of Fish And Pufa, And Clinical Depressive And Anxiety Disorders In Women, Felice N. Jacka, Julie A. Pascoe, Lana J. Williams, Barbara J. Meyer, Rebecca Digger, Michael Berk

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

Fish and PUFA consumption are thought to play a role in mental health; however, many studies do not take into account multiple sources of PUFA. The present study analysed data from a sample of 935 randomly selected, population-based women aged 20-93 years. A validated and comprehensive dietary questionnaire ascertained the consumption of n-3 and n-6 PUFA. Another assessed fish and energy intake and provided data for a dietary quality score. The General Health Questionnaire-12 (GHQ-12) measured psychological symptoms and a clinical interview (Structured Clinical Interview for DSM-IV-TR Research Version, Non-patient edition) assessed depressive and anxiety disorders. Median dietary intakes of ...


The Small Heat-Shock Protein Αb-Crystallin Uses Different Mechanisms Of Chaperone Action To Prevent The Amorphous Versus Fibrillar Aggregation Of Α-Lactalbumin, Melissa Kulig, Heath Ecroyd Sep 2012

The Small Heat-Shock Protein Αb-Crystallin Uses Different Mechanisms Of Chaperone Action To Prevent The Amorphous Versus Fibrillar Aggregation Of Α-Lactalbumin, Melissa Kulig, Heath Ecroyd

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

Stress conditions can destabilize proteins, promoting them to unfold and adopt intermediately folded states. Partially folded protein intermediates are unstable and prone to aggregation down off-folding pathways leading to the formation of either amorphous or amyloid fibril aggregates. The sHsp (small heat-shock protein) αB-crystallin acts as a molecular chaperone to prevent both amorphous and fibrillar protein aggregation; however, the precise molecular mechanisms behind its chaperone action are incompletely understood. To investigate whether the chaperone activity of αB-crystallin is dependent upon the form of aggregation (amorphous compared with fibrillar), bovine α-lactalbumin was developed as a model target protein that could be ...


Earthly Indifference And Human Difference - Book Review, Lesley Head Sep 2012

Earthly Indifference And Human Difference - Book Review, Lesley Head

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

Inspired by, but also in reaction to the flattened topologies of Latourian relationality, Clark puts forward the notion of radical asymmetry. 'This is the bottom line of human being: we are utterly dependent on an earth and a cosmos that is, to a large degree, indifferent to us' (p. 50). With their disciplinary connection to the physical and natural sciences, geographers arguably need this lesson less than other social scientists. We should have learned it well from geologists who, spending their working lives in deepest time, tend to have a less anthropocentric perspective than others (perhaps accounting for their disproportionate ...

Translocation Of The Eastern Bristlebird 2: Applying Principles To Two Case Studies, Jack Baker, David Bain, Jean Clarke, Kris French

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

The Eastern Bristlebird (Dasyornis brachypterus) is an endangered endemic passerine of south-eastern Australia. The re-establishment of extirpated populations through translocation was identified as a key action in New South Wales to address the threats to this species associated with habitat fragmentation and widespread and frequent fire. At Jervis Bay during 2003-2005, 50 birds were translocated from Bherwerre Peninsula to Beecroft Peninsula. In the Illawarra in 2008, 50 birds were translocated from Barren Grounds Nature Reserve to Cataract. At Jervis Bay, monitoring indicated that after 7 years, (i) there was no detectable impact on the source population from the removal of ...


Simulation Study Of Ion Pairing In Concentrated Aqueous Salt Solutions With A Polarizable Force Field, Yun Luo, Wei Jiang, Haibo Yu, Alexander D. Mackerrell, Benoit Roux May 2012

Simulation Study Of Ion Pairing In Concentrated Aqueous Salt Solutions With A Polarizable Force Field, Yun Luo, Wei Jiang, Haibo Yu, Alexander D. Mackerrell, Benoit Roux

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

The accuracy of empirical force fields is critical for meaningful molecular dynamics simulations of concentrated ionic solutions. Current models are typically developed on the basis of single ion properties such as the monohydrate energy in the gas phase, or the absolute hydration free energy at infinite dilution. However, the failure of these models to represent accurately the properties of concentrated solutions cannot be excluded. Here, these issues are illustrated for a polarizable potential based on classical Drude oscillators. To model accurately concentrated ionic solutions, the parameters of the potential functions are optimized to reproduce osmotic pressure data. The sodium-chloride potential ...


Polymorphic Male Color Morphs Visualized With Steroids In Monomorphic Females: A Tool For Designing Analysis Of Sex-Limited Trait Inheritance, Mats M. Olsson, Mo Healey, Mark Wilson, Michael Tobler Feb 2012

Polymorphic Male Color Morphs Visualized With Steroids In Monomorphic Females: A Tool For Designing Analysis Of Sex-Limited Trait Inheritance, Mats M. Olsson, Mo Healey, Mark Wilson, Michael Tobler

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

In diploid animals, males and females share most of the genome (except sex-specific elements, such as sex chromosome genes), yet despite sharing the underlying genes that hard-wire traits, males and females may differ in their phenotypes when traits are controlled by proximate mechanisms, such as hormones. In color polymorphic species where coloration is only expressed in one sex, the design of studies of the inheritance of color and coevolved morph-specific traits (e.g. territorial vs sneaker strategies, skewed energetic investment in territorial defense vs sperm production, etc.) is compromised as the expression of morph-coding genes is only visualized in one ...

Hate Blood But Want A Career In Medicine? Don't Worry, There's A Job For You, Ian Wilson

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

Just before I finished high school, my local general practitioner suggested I consider medicine. But the thought of blood made me feel squeamish, so I went to university to do maths and physics, and to try the new field of computer science. Needing a fourth subject, I opted for biology so that my friend who also did biology could give me a lift to campus. I ended up becoming fascinated with biology, so much so that I wanted to study neuroscience, and I felt the best way into a research career was through medicine. Luckily, I was successful. As an ...

De Combe Grenal À Pech De L'Azé Iv: L'Évolution Des Méthodes De Fouilles De François Bordes, Shannon P. Mcpherron, Harold L. Dibble, Paul Goldberg, Michel Lenoir, Dennis Sandgathe, Alain Turq

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

François Bordes excavated the site of Combe Grenal from 1953 to 1965. It was his first major excavation project in southwest France, and he applied a number of new methodologies the most important of which was three-dimensional positioning of artifaas. Bordes' last major excavation project in southwest France was the site of Pech de I'Aze IV. This excavation lasted from 1970 to 1977. We have digitized the square notebooks from both of these excavations and analyzed portions of the material from both sites. With this information we can see the evolution of Bordes' excavation techniques over the decades and ...

Fine-Resolution (25 M) Topoclimatic Grids Of Near-Surface (5 Cm) Extreme Temperatures And Humidities Across Various Habitats In A Large (200 X 300 Km) And Diverse Region, Michael B. Ashcroft, John R. Gollan Jan 2012

Fine-Resolution (25 M) Topoclimatic Grids Of Near-Surface (5 Cm) Extreme Temperatures And Humidities Across Various Habitats In A Large (200 X 300 Km) And Diverse Region, Michael B. Ashcroft, John R. Gollan

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

The development of fine-resolution climate grids is an important priority in explaining species' distributions at the regional scale and predicting how species may respond to variable and changing climates. Recent studies have demonstrated advantages of producing these grids using large networks of inexpensive climate loggers, as the resulting grids can capture local climatic variations over a range of environments. In this study we extend these methods to develop innovative fine-resolution (25 m) climate grids for a large region (∼200 x 300 km) of New South Wales, Australia. The key aspects of these grids is that they: (1) are based on ...

A Novel Approach To Quantify And Locate Potential Microrefugia Using Topoclimate, Climate Stability, And Isolation From The Matrix, Michael B. Ashcroft, John R. Gollan, David I. Warton, Daniel Ramp

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

Ecologists are increasingly recognizing the conservation significance of microrefugia, but it is inherently difficult to locate these small patches with unusual climates, and hence they are also referred to as cryptic refugia. Here we introduce a new methodology to quantify and locate potential microrefugia using fine-scale topoclimatic grids that capture extreme conditions, stable climates, and distinct differences from the surrounding matrix. We collected hourly temperature data from 150 sites in a large (200 km by 300 km) and diverse region of New South Wales, Australia, for a total of 671 days over 2 years. Sites spanned a range of habitats ...


Combining Citizen Science, Bioclimatic Envelope Models And Observed Habitat Preferences To Determine The Distribution Of An Inconspicuous, Recently Detected Introduced Bee (Halictus Smaragdulus Vachal Hymenoptera: Halictidae) In Australia, Michael B.

Combining Citizen Science, Bioclimatic Envelope Models And Observed Habitat Preferences To Determine The Distribution Of An Inconspicuous, Recently Detected Introduced Bee (Halictus Smaragdulus Vachal Hymenoptera: Halictidae) In Australia, Michael B. Ashcroft, John R. Gollan, Michael Batley

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

Introduced bees may compete with native fauna, spread parasites or pathogens to commercial bee hives, or increase the fecundity of introduced weeds. Therefore, the recent detection of Halictus smaragdulus, native to the western Palaearctic, in the Hunter Valley region of New South Wales (NSW, Australia) is cause for concern. However, it is currently difficult to justify control measures, as there is little known on its ecology, impacts and distribution. Determining the current distribution is fundamental to managing introduced species, yet this is difficult with inconspicuous species such as H. smaragdulus, especially as recent introductions are often found in low densities ...

Background There has been substantial increase in use of androgen deprivation therapy as adjuvant management of prostate cancer. However, this leads to a range of musculoskeletal toxicities including reduced bone mass and increased skeletal fractures compounded with rapid metabolic alterations, including increased body fat, reduced lean mass, insulin resistance and negative lipoprotein profile, increased incidence of cardiovascular and metabolic morbidity, greater distress and reduced quality of life. Numerous research studies have demonstrated certain exercise prescriptions to be effective at preventing or even reversing these treatment toxicities. However, all interventions to date have been of rehabilitative intent being implemented after a ...

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

Lake Ohrid shared by the Republics of Albania and Macedonia is formed by a tectonically active graben within the south Balkans and suggested to be the oldest lake in Europe. Several studies have shown that the lake provides a valuable record of climatic and environmental changes and a distal tephrostratigraphic record of volcanic eruptions from Italy. Fault structures identified in seismic data demonstrate that sediments have also the potential to record tectonic activity in the region. Here, we provide an example of linking seismic and sedimentological information with tectonic activity and historical documents. Historical documents indicate that a major earthquake ...

Experimental And Computational Simulation Of Beta-Dose Heterogeneity In Sediment, Alastair C. Cunningham, Daniel J. De Vries, Dennis R. Schaart Jan 2012

Experimental And Computational Simulation Of Beta-Dose Heterogeneity In Sediment, Alastair C. Cunningham, Daniel J. De Vries, Dennis R. Schaart

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

Interpreting the spread in equivalent-dose estimates is an important aspect of optically stimulated luminescence (OSL) dating. Ideally, prior to age estimation, an assessment should be made of the likely spread in equivalent dose due to dose-rate heterogeneity in the sediment. Such a procedure would greatly increase the validity of OSL ages, particularly for sediments susceptible to partial bleaching, and for sediments with coarse or poorly sorted grain-size distributions. In this paper we take a step towards a general model of dose-rate heterogeneity by simulating the 40K-derived beta dose to quartz. We present an experimental simulation of the 40K beta dose ...

[1] Recent studies have shown that measured OH under NOx-limited, high-isoprene conditions are many times higher than modeled OH. In this study, a detailed analysis of the HOx radical budgets under low-NOx, rural conditions was performed employing a box model based on the Master Chemical Mechanism (MCMv3.2). The model results were compared with HOx radical measurements performed during the international HOxComp campaign carried out in Jülich, Germany, during summer 2005. Two different air masses influenced the measurement site denoted as high-NOx (NO, 1-3 ppbv) and low-NOx (NO, < 1 ppbv) periods. Both modeled OH and HO2 diurnal profiles lay within the measurement range of all HOx measurement techniques, with correlation slopes between measured and modeled OH and HO2 around unity. Recently discovered interference in HO2 measurements caused by RO2 cross sensitivity was found to cause a 30% increase in measured HO2 during daytime on average. After correction of the measured HO2 data, the model HO2 is still in good agreement with the observations at high NOx but overpredicts HO2 by a factor of 1.3 to 1.8 at low NOx. In addition, for two different set of measurements, a missing OH source of 3.6 ± 1.6 and 4.9 ± 2.2 ppb h−1 was estimated from the experimental OH budget during the low-NOx period using the corrected HO2 data. The measured diurnal profile of the HO2/OH ratio, calculated using the corrected HO2, is well reproduced by the MCM at high NOx but is significantly overestimated at low NOx. Thus, the cycling between OH and HO2 is better described by the model at high NOx than at low NOx. Therefore, similar comprehensive field measurements accompanied by model studies are urgently needed to investigate HOx recycling under low-NOx conditions.

The ageing population and increasing prevalence of chronic illness have contributed to the need for significant primary care reform, including increased use of multidisciplinary care and task substitution. This cross-sectional study explores conditions under which older patients would accept having health professionals other than their general practitioner (GP) involved in their care for chronic disease management (CDM). Ten practices were randomly sampled from a contiguous major city and inner regional area. Questionnaires were distributed to consecutive patients aged 60 years and over in each practice. Agency theory was used to inform analyses. Statistical analysis was undertaken using Wald’s test ...
