Formaldehyde And Nitrogen Dioxide In Smoke Plumes From Australia's Black Saturday Fires, Emma Young, Clare Paton-Walsh 2010 University of Wollongong

Formaldehyde And Nitrogen Dioxide In Smoke Plumes From Australia's Black Saturday Fires, Emma Young, Clare Paton-Walsh

Faculty of Science - Papers (Archive)

The ‘Black Saturday’ fires were a series of devastating bushfires that burned across Victoria, Australia, during February 2009. The smoke plume from Saturday the 7th February, the worst day of the fires, separated from subsequent emissions and persisted for several weeks, providing the opportunity to track the changing composition of the smoke plume as it aged. In this study we have used satellite data from the Ozone Monitoring Instrument (OMI) and the Atmospheric InfraRed Sounder (AIRS) to characterise the emissions of formaldehyde and nitrogen dioxide from the fires. Emission ratios with respect to carbon monoxide are determined for formaldehyde (0 ...

An important concern when developing new inks containing novel, bulk, solid-state additives is to ensure consistency during the printing process. In particular, the additives should not build up on the rollers, blankets or plates during printing. In this work we describe a method for detecting such events and quantitatively monitoring, in real time, the consistency of developmental inks during commercial printing processes. The technique employs a two-component mixture of emissive nanoparticles whose ratio becomes variable in a non-homogeneous environment. Even tiny variations in the ratio can be readily and dynamically detected in real time using a fibre-optic equipped fluorescence microspectrometer ...


Patterns Of Demography For Rocky-Shore, Intertidal Invertebrates Approaching Their Geographical Range Limits: Tests Of The Abundant-Centre Hypothesis In South-Eastern Australia, Eszter Z. Hidas, David J. Ayre, Todd E. Minchinton 2010 University of Wollongong

Patterns Of Demography For Rocky-Shore, Intertidal Invertebrates Approaching Their Geographical Range Limits: Tests Of The Abundant-Centre Hypothesis In South-Eastern Australia, Eszter Z. Hidas, David J. Ayre, Todd E. Minchinton

The abundant-centre hypothesis predicts that species' abundances peak at the centre of their geographical ranges and decline gradually towards their range limits. We tested predictions of this hypothesis for three rocky-shore, intertidal invertebrates with planktonic larvae (the whelk, Morula marginalba, the snail, Afrolittorina pyramidalis, and the barnacle, Tesseropora rosea) by quantifying their patterns of abundance and size, and inferring pulses of recruitment from size-frequency distributions, at multiple spatial scales spanning a 600-km region in south-eastern Australia and encompassing roughly the southern third of their geographical ranges. At the regional scale, abundances for all species were, as predicted, dramatically lower at ...

The isolation of two new Stemona alkaloids, 1-hydroxyprotostemonine and stemocurtisine N-oxide, and a new benzofuran, stemofuran L, from the root extracts of Stemona curtisii is reported. The major known alkaloids from this plant extract, stemocurtisine, stemocurtisinol, and oxyprotostemonine, were also isolated along with oxystemokerrine N-oxide. The nonalkaloid components of this extract included a new benzofuran derivative, stemofuran L, the known stemofurans F, J, and K, dihydro-γ-tocopherol, and stigmasterol. Stemocurtisine and stemocurtisinol were converted to their respective N-oxides by oxidation. Stemocurtisine was converted to a tetracyclic derivative by oxidative cleavage of the γ-butyrolactone ring, while stemocurtisinol gave a novel lactam derivative ...

Generation of the broad spectrum protease plasmin is facilitated by the tissue (t-PA) and urokinase (u-PA) plasminogen activators, within multiple physiological and disease states. Finely tuned control of this proteolytic cascade is exerted by the plasminogen activator inhibitors type-1 (PAI-1/SERPINE1) and 2 (PAI-2/SERPINB2). Expression of this network of activators and inhibitors by cells of myeloid lineage appears to be highly interchangeable between physiological environments, and whilst the role of PAI-1 and PAI-2 in regulating u-PA-dependent functions is well established, the interaction between t-PA and PAI-2 on these cell types is poorly characterised. To this end, we used freshly ...


New Data On Occurrences Of The Devonian Rugose Coral Calceola In Belgium, Anthony J. Wright, M Coen-Aubert, P Bultynck, A P. van Viersen 2010 University of Wollongong

Opercula and corallites of Calceola sandalina from the late Eifelian and early Givetian (Middle Devonian) Hanonet Formation of Belgium are illustrated. The few previous illustrations of calceoloid corals from the Devonian of Belgium did not include opercula showing the generically diagnostic morphological features, so for the first time the presence of the genus and species in Belgium is confirmed. One important corallite shows the alar septum and insertion of septa on the external surface of the counter face adjacent to the alar septum.

In Calceola sandalina the full complement of counter major septa was established very low in the calyx, extending from the counter septum across to the edge of the counter face. At about mid-height of the calyx, a counter-lateral major septum was generated on either side of and from the counter septum. Serial minor septal insertion was initiated adjacent to the counter-lateral septa at a slightly later stage and continued throughout the subsequent ontogeny of the corallite, with minor septa (schizosepta?) arising on the median side of major septa and bifurcating from them. Alar fossulae are seen in the calyx of ...


Stratigraphic Distribution And Suggested Evolution Of Dendroid Graptolites From The Silurian Of Eastern Australia, Barrie Rickards, Anthony Wright 2010 University of Cambridge

Stratigraphic Distribution And Suggested Evolution Of Dendroid Graptolites From The Silurian Of Eastern Australia, Barrie Rickards, Anthony Wright

Faculty of Science - Papers (Archive)

Five evolutionary lineages are proposed for Silurian species of the benthic dendroid graptolite genus Dictyonema, based largely on the exceptional eastern Australian records of the genus, comprising at least 25 species. These are: A, the delicatulum lineage with bifurcating ventral autothecal apertural spines; B, the paululum lineage with single ventral apertural spines or processes; C, the elegans lineage with isolated thecal apertures ± processes; D, the sherrardae lineage with dorsal apertural processes; and E, the venustum lineage with simple autothecal apertures. Brief comments are also made on other dendroid genera occurring in Australian strata, namely: Acanthograptus, Koremagraptus, Callograptus, Dendrograptus, Stelechocladia, Thallograptus ...


What Did Grinding Stones Grind? New Light On Early Neolithic Subsistence Economy In The Middle Yellow River Valley, China, Li Liu, Judith Field, Richard Fullagar, Sheahan Bestel, Xingcan Chen, Xiaolin Ma 2010 La Trobe University, Melbourne

What Did Grinding Stones Grind? New Light On Early Neolithic Subsistence Economy In The Middle Yellow River Valley, China, Li Liu, Judith Field, Richard Fullagar, Sheahan Bestel, Xingcan Chen, Xiaolin Ma

Grinding stones have provided a convenient proxy for the arrival of agriculture in Neolithic China. Not any more. Thanks to high-precision analyses of use-wear and starch residue, the authors show that early Neolithic people were mainly using these stones to process acorns. This defines a new stage in the long transition of food production from hunter-gatherer to farmer.

The Total Carbon Column Observing Network (TCCON) produces precise measurements of the column average dry-air mole fractions of CO2, CO, CH4, N2O and H2O at a variety of sites worldwide. These observations rely on spectroscopic parameters that are not known with sufficient accuracy to compute total columns that can be used in combination with in situ measurements. The TCCON must therefore be calibrated to World Meteorological Orga-nization (WMO) in situ trace gas measurement scales. We present a calibration of TCCON data using WMO-scale instrumentation aboard aircraft that measured profiles over four TCCON stations during 2008 and 2009. These calibrations are ...

Background: Photochemical tissue bonding (PTB) is a promising sutureless technique for tissue repair. PTB is often achieved by applying a solution of rose bengal (RB) between two tissue edges, which are irradiated by a green laser to crosslink collagen fibers with minimal heat production. In this study, RB has been incorporated in chitosan films to create a novel tissue adhesive that is laser-activated. Methods: Adhesive films, based on chitosan and containing ~0.1 wt% RB were manufactured and bonded to calf intestine by a solid state laser (l = 532 nm, Fluence~110 J/cm2, spot size~0.5 cm). A ...

Invasive species may have negative impacts on many narrow range endemics and species restricted to oceanic islands. Predicting recent impacts of invasive species on long-lived trees is difficult because the presence of adult plants may mask population changes. We examined the impact of introduced black rats (Rattus rattus) on two palm species restricted to cloud forests and endemic to Lord Howe Island, a small oceanic island in the southern Pacific. We combined estimates of the standing size distribution of these palms with the proximal impacts of rats on fruit survival in areas baited to control rats and in unbaited areas ...

Lipid model membranes such as 1,2-Dimyristoyl-sn-Glycero-3-Phosphocholine (DMPC) serve as role models for their more complex counterparts in biological systems. Quasielastic neutron scattering (QENS) [1-3], inelastic neutron scattering (INS) [4] and neutron spin echo spectroscopy (NSE) [5] have been employed to study local as well as collective dynamics of these membranes on a ps-ns time scale. Most of these studies lack a systematic investigation of the behavior of the model membranes in dependence on their hydration. We now started a detailed investigation of hydration effect on model membrane systems. The complexity of the dynamics can be further reduced by selective ...

CARBON TRADING and the growing interest in biofuel production from sugarcane necessitate the ability to measure gains and losses of soil organic C which may occur as a result. Modelling and soil sampling suggest that changes in soil C are likely to be < 1 t C/ha/y. Published accounts indicate that confirming such small changes by traditional soil sampling is error-prone and requires investigations of > 10 years. The paper explores the possibility of calculating soil gains or losses by subtracting the carbon stored in the crop biomass from the carbon gained by the crop through the uptake of carbon dioxide supplied by the atmosphere and processes in the soil. Although uptake and storage very nearly balanced each other in one–year measurements ...

How are preferences for “native” and “introduced” species of plants and animals given expression in Australian cities? Given the nation's predominantly European cultural heritage, how do urban Australians articulate multiple desires for living environments encountered in everyday life? In examining the cases of inner city parks, backyards, and more general views about flora and fauna appropriate for the city, the paper considers a range of deeply enculturated attachments to familiar landscapes. While residents have considerable interest in the possibilities of urban ecological restoration, our interviews, ethnographic observation, and textual analysis also reveal cultural preferences for introduced species and emplaced ...
