Meibum is believed to be the major source of tear !lm lipids, which are vital in the prevention of excessevaporation of the aqueous phase. The complete lipid composition of meibum has yet to be established.While earlier studies reported the presence of phospholipids in human meibum, recent mass spectrometricstudies have not detected them. In this study we use electrospray ionisation tandem massspectrometry to investigate the presence of phospholipids in meibum and provide comparison to thephospholipid pro!le of tears.Lipids were extracted from human meibum and tear samples using standard biphasic methods andanalysed by nano-electrospray ionisation tandem mass spectrometry using targeted ion scans. …


Global Co(2) Fluxes Inferred From Surface Air-Sample Measurements And From Tccon Retrievals Of The Co(2) Total Column, Frederic Chevallier, Nicholas M. Deutscher, T J.

"We present the first estimate of the global distribution of CO(2) surface fluxes from 14 stations of the Total Carbon Column Observing Network (TCCON). The evaluation of this inversion is based on 1) comparison with the fluxes from a classical inversion of surface air-sample-measurements, and 2) comparison of CO(2) mixing ratios calculated from the inverted fluxes with independent aircraft measurements made during the two years analyzed here, 2009 and 2010. The former test shows similar seasonal cycles in the northern hemisphere and consistent regional carbon budgets between inversions from the two datasets, even though the TCCON inversion appears to be …

Certain limitations arise from the persistent consideration of two common relationsof islands in the humanities and social sciences: land and sea, and island andcontinent/mainland. What remains largely absent or silent are ways of being, knowing anddoing¿ontologies, epistemologies and methods¿that illuminate island spaces as inter-related,mutually constituted and co-constructed: as island and island. Therefore, this paper seeks tomap out and justify a research agenda proposing a robust and comprehensive exploration ofthis third and comparatively neglected nexus of relations. In advancing these aims, the paper¿sgoal is to (re)inscribe the theoretical, metaphorical, real and empirical power and potential ofthe archipelago: of seas studded with …

The Cu(I) halide (X = I, Br, Cl) mediated reactions of Cbz-protected cis-2-phenylethenyl-3-hydroxypyrrolidine gave novel 3-halo-2,5-trisubstituted furans in good yields, via a cyclization-halogenation, ring-opening reaction sequence. In contrast, the reactions with CuCN gave mainly the corresponding 3-cyanofuro[3,2-b]pyrrole formed from a cyclization-cyanation reaction.

The bicyclic hexaamine "cage" ligand Me 8tricosaneN 6 (1,5,5,9,13,13,20,20-octamethyl-3,7,11,15,18, 22-hexaazabicyclo[7.7.7]tricosane) is capable of encapsulating octahedral metal ions, yet its expanded cavity allows the complexed metal to adopt a variety of geometries comprising either hexadentate or pentadentate coordination of the ligand. When complexed to Cu II the lability of the metal results in a dynamic equilibrium in solution between hexadentate- and pentadentate- coordinated complexes of Me 8tricosaneN 6. Both [Cu(Me 8tricosaneN 6)](ClO 4) 2 (6-coordinate) and [Cu(Me 8tricosaneN 6)](S 2O 6) (5-coordinate) have been characterized structurally. In weak acid (pH 1) a singly protonated complex [Cu(HMe 8tricosaneN 6)] 3+ has been …

The relatively short life cycles of harpacticoid copepods makes them appropriate animals for use in tests that rapidly assess the #180, sublethal, or chronic effects of sediment contaminants. In this study, four harpacticoid copepod species (Nitocra spinipes, Tisbe tenuimana, Robertgurneya hopkinsi, and Halectinosoma sp.) were isolated from clean marine sediments, and procedures for laboratory culturing were developed. Halectinosoma sp. was abandoned due to handling difficulties. For the remaining species, the influence of food type and quantity on life-cycle progression was assessed. A mixed diet, comprising two species of algae (Tetraselmis sp. and Isochrysis sp.) and fish food (Sera …

The aim of this work is the presentation of a synthesis of available geochronological data for the basement inliers and metavolcano-sedimentary sequences which occur in the southern part of the Apiai Terrane, south-southeastern Brazil. These data, especially those obtained during the last decade, have made substantial modifi cations to the tectonic scenario of south-southeastern Brazil with the recognition of the presence of extensional basins (continental rifts) with magmatism and sedimentation at the late Paleoproterozoic (1790 - 1750 Ma) and of the Mesoproterozoic (1600 - 1450 Ma). These processes started at the late Paleoproterozoic in the Betara, Perau and Apiai Mirim …

Simulation of the land subdivision process is useful in many applied and research areas. Planners use such tools to understand potential impacts of planning regulations prior to their implementation. While the credibility of both land-use change and urban growth models would be enhanced by integrating capabilities to simulate land subdivision, such research is lacking in the published literature. Of the few subdivision tools that exist, most are either not fully-automated or are unable to generate realistic subdivision layouts. This limits their applicability, particularly for high resolution land-use change models. In this paper, we present a fully-automated land subdivision tool that …


Films, Buckypapers And Fibers From Clay, Chitosan And Carbon Nanotubes, Thomas M. Higgins, Holly Warren, Marc In Het Panhuis Jan 2011

Films, Buckypapers And Fibers From Clay, Chitosan And Carbon Nanotubes, Thomas M. Higgins, Holly Warren, Marc In Het Panhuis

Faculty of Science - Papers (Archive)

The mechanical and electrical characteristics of films, buckypapers and fiber materials from combinations of clay, carbon nanotubes (CNTs) and chitosan are described. The rheological time-dependent characteristics of clay are maintained in clay–carbon nanotube–chitosan composite dispersions. It is demonstrated that the addition of chitosan improves their mechanical characteristics, but decreases electrical conductivity by three-orders of magnitude compared to clay–CNT materials. We show that the electrical response upon exposure to humid atmosphere is influenced by clay-chitosan interactions, i.e., the resistance of clay–CNT materials decreases, whereas that of clay–CNT–chitosan increases.

This study uses computational chemistry and statistical reaction rate theory to investigate the chemically activated reaction of diacetylene (butadiyne, C4H2) with the propargyl radical (C •H2CCH) and the reaction of acetylene (C 2H2) with the i-C5H3 (CH 2CCCC•H) and n-C5H3 (CHCC •HCCH) radicals. A detailed G3SX-level C7H 5 energy surface demonstrates that the C3H3 + C4H2 and C5H3 + C2H 2 addition reactions proceed with moderate barriers, on the order of 10 to 15 kcal mol-1, and form activated open-chain C 7H5 species that can isomerize to the fulvenallenyl radical with the highest barrier still significantly below the entrance channel …

Faculty of Science - Papers (Archive)

The polymorphic deletion of Glu-155 from human glutathione transferase omega1 (GSTO1-1) occurs in most populations. Although the recombinant ΔGlu-155 enzyme expressed in Escherichia coli is active, the deletion causes a deficiency of the active enzyme in vivo. The crystal structure and the folding/unfolding kinetics of the ΔGlu-155 variant were determined in order to investigate the cause of the rapid loss of the enzyme in human cells. The crystal structure revealed altered packing around the Glu-155 deletion, an increase in the predicted solvent-accessible area and a corresponding reduction in the buried surface area. This increase in solvent accessibility was consistent with …

Inkjet Printing Of Self-Assembling Polyelectrolyte Hydrogels, Skander Limen, Donald Mccallum, Gordon G. Wallace, Marc In Het Panhuis, Paul Calvert

Faculty of Science - Papers (Archive)

Inkjet printing of alternate layers of anionic and cationic polyelectrolytes allows organized gels to form with structures similar to those made by layer-by-layer dipping methods but very much faster. Structures of gels formed using slow and fast inkjet printing systems are compared using elemental analysis, swelling and diffusion kinetics as characterization methods. After printing and washing, most sodium or chloride counter-ions are lost from the gel, leaving only the polymer complex. The swelling properties of the printed and washed gel depend on the deposition rate and on the ratio of the two polymers as originally printed.

Inkjet And Extrusion Printing Of Conducting Poly(3,4-Ethylenedioxythiophene) Tracks On And Embedded In Biopolymer Materials, Charles A. Mire, Animesh Agrawal, Gordon G. Wallace, Paul Calvert, Marc In Het Panhuis

Faculty of Science - Papers (Archive)

Two printing methods, extrusion and inkjet, are used to deposit tracks of PEDOT/PSS conducting polymer onto biopolymer films with a view to prepare implantable tissue mimics containing electronic devices. Extruded tracks offer lower printing resolution, but better electrical characteristics compared to inkjet printed tracks. The biopolymer–ink interaction results in narrower printed tracks compared to those on glass. This affects the final conductivity, which is lower for printed tracks on biopolymer than for lines printed on glass, due to the part of the track lying below the surface. Extrusion printing is used to embed tracks into a biopolymer matrix, resulting in …

α-Carboxylate radical anions are potential reactive intermediates in the free radical oxidation of biological molecules (e.g., fatty acids, peptides and proteins). We have synthesised well-defined α-carboxylate radical anions in the gas phase by UV laser photolysis of halogenated precursors in an ion-trap mass spectrometer. Reactions of isolated acetate (CH2CO 2-) and 1-carboxylatobutyl (CH3CH 2CH2CHCO2-) radical anions with dioxygen yield carbonate (CO3-) radical anions and this chemistry is shown to be a hallmark of oxidation in simple and alkyl-substituted cross-conjugated species. Previous solution phase studies have shown that Cα-radicals in peptides, formed from free radical damage, combine with dioxygen to form …

The nature of the Australian climate at about the time of rapid megafaunal extinctions and humans arriving in Australia is poorly understood and is an important element in the contentious debate as to whether humans or climate caused the extinctions. Here we present a new paleoshoreline chronology that extends over the past 100 k.y. for Lake Mega-Frome, the coalescence of Lakes Frome, Blanche, Callabonna and Gregory, in the southern latitudes of central Australia. We show that Lake Mega-Frome was connected for the last time to adjacent Lake Eyre at 50-47 ka, forming the largest remaining interconnected system of paleolakes on …


Significance Of P2x7 Receptor Variants To Human Health And Disease, Ronald Sluyter, Leanne Stokes Jan 2011

Significance Of P2x7 Receptor Variants To Human Health And Disease, Ronald Sluyter, Leanne Stokes

Faculty of Science - Papers (Archive)

The human P2X7 receptor is a trimeric ligand-gated cation channel coded by the P2RX7 gene located at chromosome position 12q24. P2X7 is expressed in a wide variety of normal and disease-associated cell types. Activation of this receptor by extracellular adenosine 5’-triphosphate results in numerous downstream events including the release of pro-inflammatory mediators, cell proliferation or death, and killing of intracellular pathogens. As a result, P2X7 plays important roles in inflammation, immunity, bone homeostasis, neurological function and neoplasia. The P2RX7 gene encodes a P2X7 subunit 595 amino acids in length, however splice isoforms that can alter receptor expression and function, and …


Alunite Formation Within Silica Stalactites From The Sydney Region, South-Eastern Australia, Robert A. Wray Jan 2011

Alunite Formation Within Silica Stalactites From The Sydney Region, South-Eastern Australia, Robert A. Wray

Faculty of Science - Papers (Archive)

"This paper presents X-ray diffraction and SEM evidence for the formation of alunite, and possibly small quantities of natroalunite, within opal-A stalactites formed on quartz sandstone near Sydney in south-eastern, Australia. Alunite has been reported as a speleogenetic mineral from sediments within a number of caves around the world, but this is believed to be the first report of speleothemic alunite in opaline silica speleothems. Individual alunite crystals have not been visually identified, but SEM X-ray element mapping suggests the alunite has formed amongst kaolinite clay. Sedimentary alunite and natroalunite formation is usually associated with the reaction of sulphuric acid …

Traditionally, suburbs have been conceived as dormitory – in binary opposition to the inner-city (Powell). Supporting this stereotypical view have been gendered binaries between inner and outer city areas; densely populated vs. sprawl; gentrified terraces and apartment culture vs. new estates and first home buyers; zones of (male) production and creativity against (female) sedate, consumer territory. These binaries have for over a decade been thoroughly criticised by urban researchers, who have traced such representations and demonstrated how they are discriminatory and incorrect (see Powell; Mee; Dowling and Mee). And yet, such binaries persist in popular media commentaries and even in …

Faculty of Science - Papers (Archive)

Membrane biological reactors combine the use of biological processes and membrane technology to treat wastewater. The use of biological treatment can be traced back to the late nineteenth century. It became a standard method of wastewater treatment by the 1930s (Rittmann, 1987). Both aerobic and anaerobic biological treatment methods have been extensively used to treat domestic and industrial wastewater (Visvanathan et al., 2000). After removal of the soluble biodegradable matter in the biological process, any biomass formed needs to be separated from the liquid stream to produce the required effluent quality. In the conventional process, a secondary settling tank is …
