Australian Adolescents' Compliance With Sun Protection Behaviours During Summer: The Importance Of The School Context, Melinda Williams, Sandra C. Jones, Peter Caputi, Donald Iverson

Faculty of Health and Behavioural Sciences - Papers (Archive)

Adolescents exhibit significantly lower sun protection behaviours than adults in Australia. While many studies have assessed the sun protection behaviours of adolescents during summer, few studies have explored the differences in sun protection behaviours of adolescents across key contexts relevant to adolescents during summer—notably school time, weekends and school holidays. Greater understanding of differences in behaviours across these contexts provides more detailed explanations of the nature of adolescent ultraviolet exposure and thereby facilitates improved targeting of interventions for this segment whose behaviour is considered hard to change. In this study, we explore the differences in self-reported, habitual, sun protection behaviours …

Vection During Conflicting Multisensory Information About The Axis, Magnitude And Direction Of Self-Motion, April Ash, Stephen Palmisano

Faculty of Health and Behavioural Sciences - Papers (Archive)

We examined the vection induced by consistent and conflicting multisensory information about self-motion. Observers viewed displays simulating constant-velocity self-motion in depth while physically oscillating their heads left ^ right or back ^ forth in time with a metronome. Their tracked head movements were either ignored or incorporated directly into the self-motion display (as an added simulated self-acceleration). When this head oscillation was updated into displays, sensory conflict was generated by simulating oscillation along: (i) an orthogonal axis to the head movement; or (ii) the same axis, but in a non-ecological direction. Simulated head oscillation always produced stronger vection than `no …

What Influences Australian Women To Not Drink During Pregnancy?, Sandra C. Jones, Joanne Telenta

Faculty of Health and Behavioural Sciences - Papers (Archive)

There is a strong social norm against consuming alcohol during pregnancy. However, many women do not realise they are pregnant until the sixth week and are not provided with information about the risks of consuming alcohol until they visit a health professional in the second trimester. We conducted semi-structured interviews with 12 midwives and 12 pregnant women from two regions inNSWin 2008–09 to explore attitudes towards alcohol consumption during pregnancy, and the factors that may encourage or inhibit women from following the recommendation to abstain from drinking while pregnant. Both groups noted the social issues around pregnant women consuming alcohol …

Two sediment types were found in five gravity cores collected from water depths between 56 m and 121 m along the northwestern continental margin of India: lime muds were abundant in the lower section while siliciclastic sediments dominated the upper section. Lime mud-dominated sediments in shelf cores contained 60%–75% carbonate, 0.3%–0.6% Sr and terrigenous minerals, whereas those at the shelf break were found to have >90% carbonate, 0.6%–0.8% Sr and traces of terrigenous minerals. Aragonite needles showing blunt edges, jointed needles and needles wrapped in smooth aragonite cement were found to be common. Stable (O and C) isotopes of lime …

A Pluvial Episode Identified In Arid Australia During The Medieval Climatic Anomaly, T J. Cohen, G C. Nanson, J D. Jansen, L A. Gliganic, J.-H May, J R. Larsen, I D. Goodwin, S Browning, D M. Price

Faculty of Science - Papers (Archive)

Optically stimulated luminescence (OSL) ages from a relict shoreline on Lake Callabonna record a major pluvial episode in southern central Australia between 1050 ± 70 and 1100 ± 60 Common Era (CE), within the Medieval Climatic Anomaly (MCA). During this pluvial interval Lake Callabonna filled to 10–12 times the volume of the largest historical filling (1974) and reached maximum depths of 4–5 m, compared to the 0.5–1.0 m achieved today. Until now there has been no direct evidence for the MCA in the arid interior of Australia. A multi-proxy, analogue-based atmospheric circulation reconstruction indicates that the pluvial episode was associated …

Is It Important To Position Foot In Subtalar Joint Neutral Position During Non-Weight-Bearing Molding For Foot Orthoses?, Winson Lee, Christina Lee, Aaron Leung, Stephen W. Hutchins

Faculty of Engineering and Information Sciences - Papers: Part A

When taking molds for foot orthoses, it is accepted practice to position the subtalar joint in its neutral position. However, foot orthoses have no contact with the talus, and this leads to a hypothesis that as long as there is correction available to appropriately align the forefoot relative to the hindfoot when taking a mold, changes in subtalar joint angles do not lead to significant alterations in the plantar surface shapes of the molds taken. This study tested this presumption with 20 subjects between 22 and 46 years old. During non-weight-bearing casting, the subtalar joints were aligned at positions of …

Acoustic Emission Monitoring Of Split Formation During Charpy Impact Testing Of High Strength Steel, Andrii Kostryzhev, R B. Punch, Claire L. Davis, Martin Strangwood

Faculty of Engineering and Information Sciences - Papers: Part A

Acoustic emission (AE) monitoring has been used to detect split formation during room temperature low blow Charpy impact testing of high strength thick strip steels. The AE signal analysis identified separate signals originating from hammer impact, plastic deformation (verified using Charpy impact testing on mild steel with no splits) and split initiation/growth. The presence of splits was confirmed by sectioning and fractography, and the splits were brittle in nature. A possible correlation between the AE signal features and fracture mode is presented.

Strain-Induced Phase Transformation During Thermo-Mechanical Processing Of Titanium Alloys, A Dehghan-Manshadi, Rian J. Dippenaar

Faculty of Engineering and Information Sciences - Papers: Part A

Strain-induced phase transformation studies have been conducted in a Ti-6Al-2Sn-4Zr-6Mo alloy. This alloy was subjected to b sub-transus deformation upon slow cooling from the b-phase field and the effect of strain on the extent and morphology of the phase transformation during hot-deformation was determined. In addition, the transformation kinetics and the morphology of the newly formed a-phase were studied following deformation under different cooling conditions. By applying strain, the rate of the b-to-a phase transformation increased significantly during deformation as well as during slow cooling following deformation. This increase in the kinetics of the b-to-a transformation can be ascribed to …

Thermal, Microstructural And Mechanical Coupling Analysis Model For Flatness Change Prediction During Run-Out Table Cooling In Hot Strip Rolling, Xiao-Dong Wang, Fei Li, Zheng-Yi Jiang

Faculty of Engineering and Information Sciences - Papers: Part A

Non-uniformity of temperature distribution across strip width direction is the ultimate reason why the flatness defect occurs on the strip after cooling process although the strip is flat at the exit of finishing mill. One thermal, microstructural and mechanical coupling analysis model for predicting flatness change of steel strip during the run-out table cooling process was established using ABAQUS finite element software. K Esaka phase transformation kinetics model was employed to calculate the phase transformation, and coupled with temperature calculation using the user subroutine program HETVAL. Elasto-plasticity constitutive equations of steel material, in which conventional elastic and plastic strains, thermal …

Sex And Censorship During The Occupation Of Japan, Mark J. Mclelland

Faculty of Arts - Papers (Archive)

This chapter entitled “Sex and Censorship During the Occupation of Japan” is excerpted from Mark McLelland’s Love, Sex and Democracy in Japan during the American Occupation (Palgrave MacMillan 2012). The book examines the radical changes that took place in Japanese ideas about sex, romance and male-female relations in the wake of Japan’s defeat and occupation by Allied forces at the end of the Second World War. Although there have been other studies that have focused on sexual and romantic relationships between Japanese women and US military personnel, little attention has been given to how the Occupation impacted upon the courtship …

Analysis Of Thermal Stress During Of Twin-Roll Casting Of Magnesium Alloy, Yucheng Zhang, T Han, Zhengyi Jiang, Dongbin Wei

Faculty of Engineering and Information Sciences - Papers: Part A

The process of twin-roll casting including pouring, solidifying, rolling and cooling can be accomplished in a very short time. Consequently, some important process parameters in the twin-roll casting that are difficult to be obtained in experiment can be acquired using numerical simulation. In this paper, a numerical simulation based on a 2D finite element model of vertical twin-roll strip casting of magnesium alloy has been conducted, and the thermal stress fields are significantly discussed. The influences of key process parameters consisting of submerged nozzle depth and nozzle spray angle have been studied. The thermal cracks on the surface of the …
