Pore-water chemistry of ODP Leg 114 holes

Pore-water samples were recovered at five sites from ODP Leg 114 in the subantarctic South Atlantic Ocean and analyzed for pH, alkalinity, chloride, sulfate, fluoride, silica, magnesium, calcium, strontium, potassium, lithium, and barium. At sites in the East Georgia Basin and on the Islas Orcadas Rise, Ca increases and Mg decreases linearly downhole with a DeltaMg/DeltaCa ratio reflecting conservative diffusive exchange and basalt basement reactions. At sites on the west flank of the Mid-Atlantic Ridge and on the Meteor Rise, Ca gradients are nonlinear, and nonconservative DeltaMg/DeltaCa ratios reflect alteration reactions of abundant silicic volcanic ash in the sediment. K decreases linearly downhole at all sites, reflecting uptake by basement and the absence of significant sediment-hosted reactions. SO4 decreases and alkalinity increases downhole are due to a slight sulfate reduction at all sites except at Site 701. Sr increases downhole at all sites except Site 701, with DeltaSr/DeltaCa ratios reflecting diffusive exchange with basement. At Site 704 on the Meteor Rise, there is intense Sr production during carbonate recrystallization in the upper 200 mbsf. Below 200 mbsf at Site 704, the ion concentration product of SrSO4 is constant, suggesting Sr control by celestite solubility. Li and F concentrations display complex behavior related to sedimentary reactions, probably calcite recrystallization (Li uptake and F release).

Weather variability, tides, and Barmah Forest Virus Disease in the Gladstone region, Australia

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.

Thermal treatment of weddellite—a Raman and infrared emission spectroscopic study

Thermal transformations of natural calcium oxalate dihydrate known in mineralogy as weddellite have been undertaken using a combination of Raman microscopy and infrared emission spectroscopy. The vibrational spectroscopic data was complimented with high resolution thermogravimetric analysis combined with evolved gas mass spectrometry. TG–MS identified three mass loss steps at 114, 422 and 592 °C. In the first mass loss step water is evolved only, in the second and third steps carbon dioxide is evolved. The combination of Raman microscopy and a thermal stage clearly identifies the changes in the molecular structure with thermal treatment. Weddellite is the phase in the temperature range up to the pre-dehydration temperature of 97 °C. At this temperature, the phase formed is whewellite (calcium oxalate monohydrate) and above 114 °C the phase is the anhydrous calcium oxalate. Above 422 °C, calcium carbonate is formed. Infrared emission spectroscopy shows that this mineral decomposes at around 650 °C. Changes in the position and intensity of the C=O and C---C stretching vibrations in the Raman spectra indicate the temperature range at which these phase changes occur.

Extreme Sports: A positive transformation in courage and humility

Extreme sports and extreme sports participants have been most commonly explored from a negative perspective, for example the “need to take unnecessary risks.” This study explored what can be learned from extreme sports about courage and humility - two positive psychology constructs. A phenomenological method was used via unstructured interviews with 15 extreme sports participants and other first hand accounts. The extreme sports included B.A.S.E. jumping, big wave surfing, extreme skiing, waterfall kayaking, extreme mountaineering and solo rope-free climbing. Results indicate that humility and courage can be deliberately sought out by participating in activities that involve a real chance of death, fear and the realisation that nature in its extreme is far greater and more powerful than humanity.

Departing from the virtual community : a discussion of the ways and means to uncover localised order in online games

This paper is part one of a three part study into the collective regulation processes of players in massive multiplayer online games (MMOG). Traditionally game playing has not been classed as problematic, however with introduction of new media technologies and new ways to play games, certain contexts have become obscure, namely the localised order of ‘playing online’ or how players manage and maintain order between each other as opposed to ‘following the rules’. Principally this paper will examine concepts of ‘virtual community’. These will be illustrated as particularly unhelpful when considering how people conduct themselves in these spaces. Thus, ‘virtual community’ will be seen as critical in implicating various online behaviours as superior to other online behaviours causing obscurity and blurring actions. This obscurity is grounded by strong associations in the virtual community as logic of practise in and of itself; behaviours that fall outside this category become common sense and as such are made invisible for investigation. This paper will draw upon the theories of Basil Bernstein and Pierre Bourdieu to produce a distinction between online behaviours and ultimately make them visible for further investigation. In doing so this paper seeks to form a basis for future research where interaction in these spaces can be identified as belonging to a certain framework to inform the design of online games and applications more effectively.

Synthesis and characterisation of cobalt hydroxide, cobalt oxyhydroxide and cobalt oxide nanodiscs

Cobalt hydroxide, cobalt oxyhydroxide and cobalt oxide nanomaterials were synthesized through simple soft chemistry. The cobalt hydroxide displays hexagonal morphology with clear edges 20 nm long. This morphology and nanosize is retained through to cobalt oxide Co3O4 through a topotactical relationship. Cobalt oxyhydroxide and cobalt oxide nanomaterials were synthesized through oxidation and low temperature calcination from the as-prepared cobalt hydroxide. Characterisation of these cobalt-based nanomaterials were fully developed, including X-ray diffraction, transmission electron microscopy combined with selected area electron diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, and thermal gravimetric analysis. Bonding of the divalent cobalt hydroxide from the oxyhydroxide and oxides by studying their high resolution XPS spectra for Co 2p3/2 and O 1s. Raman spectroscopy of the as-prepared Co(OH)2, CoO(OH) and Co3O4 nanomaterials characterised each material. The thermal stability of the materials Co(OH)2 and CoO(OH) were established. This research has developed methodology for the synthesis of cobalt oxide and cobalt oxyhydroxide nanodiscs at low temperatures.

Online nail art application : proceeding of the project development

Online Nail Artist (ONA) project aims to create a web-based application for nail salon customers. The application will help customers to customize their hands virtually and find suitable nail colors. The main research question is to reconfigure user experience in relation to product service in terms of customization of user needs. As results, the key function of the application will be to customize a virtual hand image by selecting a matched skin tone, a nail length, and a nail shape in accordance with their hands. The objectives of the project proceeding are to 1) identify customers’ experience in relation to the product features through preliminary research on existing products; 2) create a conceptual framework of the project development in order to reflect the user experience identified; and 3) present a mock up which include key features of the ONA for the future development.

Implications of precursor chemistry on the alkaline hydrothermal synthesis of titania/titanate nanostructures

A systematic study of four parameters within the alkaline hydrothermal treatment of three commercial titania powders—anatase, rutile, and Degussa P25—was made. These powders were treated with 5, 7.5, 9, and 10 M NaOH between 100 and 220 °C for 20 h. The effects of alkaline concentration, hydrothermal temperature, and precursor phase and crystallite size on the resultant nanostructure formation have been studied through X-ray diffraction, Raman spectroscopy, transmission electron microscopy, and nitrogen adsorption. Through the correlation of these data, morphological phase diagrams were constructed for each commercial powder. Interpretation of the resultant morphological phase diagrams indicates that alkaline concentration and hydrothermal temperature affect nanostructure formation independently, where nanoribbon formation is significantly influenced by temperature for initial formation. The phase and crystallite size of the precursor also significantly influenced nanostructure formation, with rutile displaying a slower rate of precursor consumption compared with anatase. Small crystallite titania precursors formed nanostructures at reduced hydrothermal temperatures.
