The paper presents the results of optical dating of potassium-rich feldspar grains obtained from the Haua Fteah cave in Cyrenaica, northeast Libya, focussing on the chronology of the Deep Sounding excavated by Charles McBurney in the 1950s and re-excavated recently. Samples were also collected from a 1.25 m-deep trench (Trench S) excavated during the present project below the basal level of the Deep Sounding. Optically stimulated luminescence (OSL) data sets for multi-grain, single aliquots of quartz for samples from the Middle Trench were previously published. Re-analyses of these OSL data confirm significant variation in the dose saturation levels of the …

Re-Examining "Redesign" In Critical Literacy Lessons With Grade 6 Students, Jessica Mantei, Lisa K. Kervin
Faculty of Social Sciences - Papers (Archive)
In children's literary texts, ideologies aligning readers with discourses of certain communities often remain uncontested, potentially privileging those views and values over others. Critical literacy, therefore, is important so children can contest positions taken in literary texts and consider how their own texts in turn position others. This inquiry examined redesign as a pedagogical approach for developing critical literacy with 12 year old students as they deconstructed messages they identified in a short film and then reconstructed alternative viewpoints with new digital literary texts (redesigns). Findings revealed that the redesign cycle supported learners as they moved through a process of …

Controlled And Scalable Torsional Actuation Of Twisted Nylon 6 Fiber, Shazed Aziz, Sina Naficy, Javad Foroughi, Hugh Ralph Brown, Geoffrey M. Spinks
Faculty of Engineering and Information Sciences - Papers: Part A
Large-scale torsional actuation occurs in twisted fibers and yarns as a result of volume change induced electrochemically, thermally, photonically, and other means. A quantitative relationship between torsional actuation (stroke and torque) and volume change is here introduced. The analysis is based on experimental investigation of the effects of fiber diameter and inserted twist on the torsional stroke and torque measured when heating and cooling nylon 6 fibers over the temperature range of 26-62 °C. The results show that the torsional stroke depends only on the amount of twist inserted into the fiber and is independent of fiber diameter. The torque …

Faculty of Engineering and Information Sciences - Papers: Part A
Terahertz spectroscopy of benzoic acid (BA) and two of its derivatives, 2-hydroxybenzoic acid (2OH-BA) and 3-hydroxybenzoic acid (3OH-BA), has been investigated in the spectral region 200 to 500 cm-1 (6.06 to 15.15 THz). The spectra show distinct absorption features. There is agreement between some of the absorption lines observed for these compounds, despite a shift in energy, which is attributed to the differences in the molecular structures. Numerical modelling gave corresponding absorption lines, and this helped in the assignment. Temperature dependence studies revealed that most of the absorption lines are composite lines in this frequency region.

This study examined the classification accuracy of the activPAL™, including total time spent sedentary and total number of breaks in sedentary behavior (SB) in 4-6 year old children. Forty children aged 4-6 years (5.3±1.0 years) completed a ~150-min laboratory protocol involving sedentary, light and moderate-to vigorous-intensity activities. Posture was coded as sit/lie, stand, walk or 'other' using direct observation. Posture was classified using the activPAL™ software. Classification accuracy was evaluated using sensitivity, specificity and area under the receiver operating characteristic curve (ROC-AUC). Time spent in each posture and total number of breaks in SB were compared using paired sample t-tests. …

A 3D elastic–plastic finite element method (FEM) model of cold strip rolling for 6-high continuous variable crown (CVC) control rolling mill was developed. This model considers the boundary conditions such as accurate CVC curves, total rolling forces, total bending forces and roll shifting values. The rolling force distributions were obtained by the internal iteration processes instead of being treated as model boundary conditions. The calculated error has been significantly reduced by the developed model. Based on the rolling schedule data from a 1,850-mm CVC cold rolling mill, the absolute error between the simulated results and the actual values is obtained …

A Comparative Study For Wear Resistant Of Stellite 6 Coatings On Nickel Alloy Substrate Produced By Laser Cladding, Hvof And Plasma Spraying Techniques, Alain Kusmoko, Druce P. Dunne, Huijun Li
Faculty of Engineering and Information Sciences - Papers: Part A
Stellite 6 coatings were deposited using laser cladding, high velocity oxygen fuel (HVOF) thermal spraying and plasma spraying techniques on a nickel alloy substrate. The surface roughness, chemical composition and microstructure of these coatings were characterised by a surface profilometer, optical microscopy (OM) and scanning electron microscopy (SEM). The microhardness of the coatings was measured and the wear behaviour of the coatings was examined under controlled test conditions in a pin-on-plate (reciprocating) tribometer. The results showed that fully dense and crack-free laser clad Stellite 6 coatings can be formed on a high nickel steel substrate. Average microhardness values of the …

Deposition Of Stellite 6 On Nickel Superalloy And Mild Steel Substrates With Laser Cladding, Alain Kusmoko, Druce P. Dunne, Huijun Li, David J. Nolan
Faculty of Engineering and Information Sciences - Papers: Part A
Stellite 6 was deposited by laser cladding of two different steel substrates (nickel superalloy and mild steel). The chemical compositions and microstructures of these coatings were characterized by atomic absorption spectroscopy, optical microscopy and scanning electron microscopy. The microhardness of the coatings was measured and the wear mechanism of the coatings was examined using a pin-on-plate (reciprocating) wear testing machine. The results showed less cracking and pore development for Stellite 6 coatings applied to the mild steel (MS) substrate. Further, the Stellite coating on mild steel was significantly harder than that deposited on the superalloy. The wear test results showed …

Several regulatory bodies have approved a health claim on the cholesterol-lowering effects of oat β-glucan at levels of 3·0 g/d. The present study aimed to test whether 1·5 g/d β-glucan provided as ready-to-eat oat flakes was as effective in lowering cholesterol as 3·0 g/d from oats porridge. A 6-week randomised controlled trial was conducted in eighty-seven mildly hypercholesterolaemic ( ≥ 5 mmol/l and < 7·5 mmol/l) men and women assigned to one of three diet arms (25 % energy (E%) protein; 45 E% carbohydrate; 30 E% fat, at energy requirements for weight maintenance): (1) minimal β-glucan (control); (2) low-dose oat β-glucan (1·5 g β-glucan; oats low – OL) or (3) higher dose oat β-glucan (3·0 g β-glucan; oats high – OH). Changes in total cholesterol and LDL-cholesterol (LDL-C) from baseline were assessed using a linear mixed model and repeated-measures ANOVA, adjusted for weight change. Total cholesterol reduced significantly in all groups ( − 7·8 (sd 13·8) %, − 7·2 (sd 12·4) % and − 5·5 (sd 9·3) % in the OH, OL and control groups), as did LDL-C ( − 8·4 (sd 18·5) %, − 8·5 (sd 18·5) % and − 5·5 (sd 12·4) % in the OH, OL and control groups), but between-group differences were not significant. In responders only (n 60), β-glucan groups had higher reductions in LDL-C ( − 18·3 (sd 11·1) % and − 18·1 (sd 9·2) % in the OH and OL groups) compared with controls ( − 11·7 (sd 7·9) %; P = 0·044). Intakes of oat β-glucan were as effective at doses of 1·5 g/d compared with 3 g/d when provided in different food formats that delivered similar amounts of soluble β-glucan.
Dietary Docosahexaenoic Acid (22:6) Incorporates Into Cardiolipin At The Expense Of Linoleic Acid (18:2): Analysis And Potential Implications, Colin Cortie, Paul L. Else
Dietary Docosahexaenoic Acid (22:6) Incorporates Into Cardiolipin At The Expense Of Linoleic Acid (18:2): Analysis And Potential Implications, Colin Cortie, Paul L. Else
Faculty of Science, Medicine and Health - Papers: part A
Cardiolipin is a signature phospholipid of major functional significance in mitochondria. In heart mitochondria the fatty acid composition of cardiolipin is commonly viewed as highly regulated due to its high levels of linoleic acid (18:2n − 6) and the dominant presence of a 4×18:2 molecular species. However, analysis of data from a comprehensive compilation of studies reporting changes in fatty acid composition of cardiolipin in heart and liver mitochondria in response to dietary fat shows that, in heart the accrual of 18:2 into cardiolipin conforms strongly to its dietary availability at up to 20% of total dietary fatty acid and …

Lipid-induced insulin resistance is associated with intracellular accumulation of inhibitory intermediates depending on the prevalent fatty acid (FA) species. In cultured myotubes, ceramide and phosphatidic acid (PA) mediate the effects of the saturated FA palmitate and the unsaturated FA linoleate, respectively. We hypothesized that myriocin (MYR), an inhibitor of de novo ceramide synthesis, would protect against glucose intolerance in saturated fat-fed mice, while lisofylline (LSF), a functional inhibitor of PA synthesis, would protect unsaturated fat-fed mice. Mice were fed diets enriched in saturated fat, n-6 polyunsaturated fat, or chow for 6 wk. Saline, LSF (25 mg/kg · d), or MYR …

This paper examines the role of powerful entities and coalitions in shaping international accounting standards. Specifically, the focus is on the process by which the International Accounting Standards Board (IASB) developed IFRS 6, Exploration for and Evaluation of Mineral Resources. In its Issues Paper, the IASB recommended that the successful efforts method be mandated for pre-production costs, eliminating the choice previously available between full cost and successful efforts methods. In spite of the endorsement of this view by a majority of the constituents who responded to the Issues Paper, the final outcome changed nothing, with choice being retained. A compelling …

Technical report IEC/TR 61000-3-6 is widely used as a guide to harmonic management in HV and MV networks, assisting in coordination of harmonic levels between utility and customer. In 2001, Australia and New Zealand adopted the harmonic standard AS/NZS 61000.3.6, which closely follows the above IEC technical report. As a result, transmission utilities and connected loads are required by government regulations to abide by the harmonic allocations set by the standard. The technical report contains some useful general principles which can be applied to the harmonic management of power systems. However, unexpected difficulties can be found when attempts are made …

Multiple myeloma is characterized by accelerated production of the proteolytic enzyme matrix metalloproteinase (MMP)-9. We hypothesized that myeloma- produced MMP-9 may influence the rate of bone turnover in a paracrine manner. Thus, we examined the correlations of MMP-9 levels, disease severity, and bone turnover rate as evaluated by markers of bone formation and resorption. Thirty-seven newly diagnosed multiple myeloma patients (nine of Durie-Salmon stage I, 12 of stage II and 16 of stage III) and 12 age-matched controls were studied. Serum MMP-9 levels were significantly higher at stage II compared to stage I (188.78"91.27 vs. 59.25"33.09 ng/mL, p-0.004). Additionally, free …

We investigated the effect of organically modified clay on the thermal and flammability behavior of nylon 6 nanocomposites. We also used zinc borate along with layered silicate with an aim of achieving synergistic effect in flame retardancy. It is found that addition of 10 wt% clay reduced the onset decomposition (5% wt loss) temperature of nylon 6 by 20°C, while addition of 5 wt% zinc borate and 5 wt% clay in combination reduced it by around 10°C. Differential thermogravimetric analysis indicated that the peak decomposition temperature was not affected by the addition of clay, but the rate of weight loss …

The effects of diets high in n-3 polyunsaturated fatty acids (PUFA; provided by fish oil), n-6 PUFA (sunflower oil) or in more-saturated fatty acids (tallow) on the distribution of subclasses of choline phospholipids (PC) and ethanolamine phospholipids (PE) from the breast muscle of broiler chickens were examined. Supplementation with the different fatty acids had no effect on the distribution of phospholipid subclasses. Feeding sunflower oil or tallow gave a molecular-species profile similar in both fatty acid subtype and proportion. In the diacyl PC phospholipids, 16: 0–18: 1n-9 and 16: 0–18: 2n-6 accounted for approximately …

The effects of dietary saturated fatty acids and polyunsaturated fatty acids (PUFA) of the n-3 and n-6 series on weight gain, body composition and substrate oxidation were investigated in broiler chickens. At 3 weeks of age three groups of chickens (n 30; ten birds per group) were fed the fat-enriched experimental diets for 5 weeks. These diets were isonitrogenous, isoenergetic and contained 208 g protein/kg and 80 g edible tallow, fish oil or sunflower oil/kg; the dietary fatty acid profiles were thus dominated by saturated fatty acids, n-3 PUFA or n-6 PUFA respectively. Resting RQ …

This book is about extending good practice in curriculum development and supporting and sustaining the positive practices that characterise many early childhood settings. The curriculum cannot be seen in isolation and it cannot exist without a strong and well-developed framework of support, the social and institutional context in which curriculum 'happens'. To develop and deliver a sound curriculum the staff must be well informed about child development and culture and about subject knowledge and appropriate ways of 'teaching' young children so that all the children in their setting can access the curriculum. Time needs to be spent developing shared perspectives …
