    Abstract: The use of P fertilizer in Eucalyptus plantations can result in significant and economically viable increases in timber production. Soil analyses could potentially indicate sites requiring more P fertilizer than is currently applied and prevent excess P fertilizer application on sites where little or no response would be obtained. The ability of several soil P analyses to predict first year growth responses of E. nitens and E. globulus to P fertilizer was assessed in 24 previously established field experiments situated in southeast and southwest Australia on a range of soil types. Soil P analyses that were assessed included an intensity‐based analysis (CaCl 2 extracted P), quantity‐based analyses (total P, bicarbonate extracted P, and Bray No. 2 P), and quantity–intensity relationships (P adsorption curves). An excellent relationship was found between CaCl 2 ‐extractable P (range: 26–162 μg kg −1 , R 2 = 0.83) and first year growth response to P applied at planting for 21 of the 24 field experiments. Quantity‐based P analyses, such as bicarbonate P (range: 2–63 μg g −1 , R 2 = 0.43), Bray No. 2 P (range: 0.1–15 μg g −1 , R 2 = 0.30), acid‐extractable P (range: 0.6–11 μg g −1 , R 2 = 0.37), and total P (range: 0.038–3.5 mg g −1 , R 2 = 0.39) did not correlate as well with plant growth response to P application. However, quantity‐based P analyses may be useful if specific calibrations were developed for a limited range of soils. Inclusion of P adsorption data in multiple regressions of soil P concentration against relative yield generally did not improve the relationships. The excellent relationship between plantation response to P fertilizer and soil P intensity suggested that such analyses may be useful for managing P fertilizer in eucalypt plantations across the wide range of sites where eucalypts are currently being planted.

    Abstract: BACKGROUND: Poly(ethylene terephthalate) (PET) is widely used in the packaging industry. In order to enhance the mechanical and barrier properties, nanoscale fillers are added to PET matrices to form nanocomposites. In the work reported here, a melt‐processed PET/synthetic mica nanocomposite sheet was characterised to determine the effect of the incorporation of synthetic mica on the sheet properties and also to see if these properties are an indicator of subsequent performance under high‐speed, high‐temperature biaxial deformation, typical of processes such as stretch blow moulding. RESULTS: The incorporation of synthetic mica was found to enhance the modulus, particularly above the glass transition temperature, and barrier properties of the extruded sheet and it significantly altered the deformation behaviour of PET under biaxial deformation. The plastic flow of PET during biaxial deformation was found to diminish for the nanocomposites, and strain hardening occurred earlier. CONCLUSION: The modulus and barrier properties of PET were enhanced by the incorporation of synthetic mica. Clay loading also altered the biaxial deformation behaviour of PET.

    Abstract: Although drinking for tension reduction has long been posited as a risk factor for alcohol‐related problems, studies investigating anxiety in relation to risk for alcohol problems have returned inconsistent results, leading researchers to search for potential moderators. Negative urgency (the tendency to become behaviorally dysregulated when experiencing negative affect) is a potential moderator of theoretical interest because it may increase risk for alcohol problems among those high in negative affect. This study tested a cross‐sectional mediated moderation hypothesis whereby an interactive effect of anxiety and negative urgency on alcohol problems is mediated through coping‐related drinking motives. Methods The study utilized baseline data from a hazardously drinking sample of young adults ( N  = 193) evaluated for participation in a randomized controlled trial of naltrexone and motivational interviewing for drinking reduction. Results The direct effect of anxiety on physiological dependence symptoms was moderated by negative urgency such that the positive association between anxiety and physiological dependence symptoms became stronger as negative urgency increased. Indirect effects of anxiety and negative urgency on alcohol problems (operating through coping motives) were also observed. Conclusions Although results of the current cross‐sectional study require replication using longitudinal data, the findings suggest that the simultaneous presence of anxiety and negative urgency may be an important indicator of risk for alcohol use disorders via both direct interactive effects and indirect additive effects operating through coping motives. These findings have potentially important implications for prevention/intervention efforts for individuals who become disinhibited in the context of negative emotional states.

    Abstract: The global demand for providing nutritious, sustainable, and safe diets for a 10 billion population by 2050 while preserving affordability, reducing environmental impacts, and adapting to climate change will require accelerating the transition to sustainable agri‐food systems. A plausible way to help tackle these challenges is by developing new plant varieties that have improved crop yield, plant nutritional quality, and sustainability (or resilience) traits. However, stakeholders, consumers, and citizens' concerns and appreciation of future‐proofing crops and the acceptability of new plant breeding strategies are not well‐established. These groups are actors in the agri‐food systems, and their views, values, needs, and expectations are crucial in helping to co‐design fair, ethical, acceptable, sustainable, and socially desirable policies on new plant breeding techniques (NPBTs) and the transition to sustainable agri‐food systems. In this study, we engaged with consumer experts and societal stakeholders to consider their perceptions, expectations, and acceptability of improving crops and NPBTs for future‐proofing the agri‐food systems. Our analysis points to a need for governments to take a proactive role in regulating NPBTs, ensure openness and transparency in breeding new crop varieties, and inform consumers about the effects of these breeding programmes and the risks and benefits of the new crop varieties developed. Consumer experts and societal stakeholders considered these strategies necessary to instil confidence in society about NPBTs and accelerate the transition to sustainable agri‐food systems.

    Abstract: Nanocomposites of poly(ethylene terephthalate) PET with a partially synthetic fluoromica were prepared by melt mixing and extruded into sheet and subjected to large‐scale biaxial stretching. Transmission electron microscopy (TEM) analysis of the mica tactoids showed that biaxial stretching had caused the tactoids to be more orientated and with improved exfoliation. The moduli of the nanocomposites were enhanced with increasing mica loading and the reinforcement effect was higher when the stretch ratio was 2 or 2.5, accommodated by having more aligned tactoids and reduced agglomeration. Enhancement in modulus was less pronounced for a stretch ratio of 3. Storage modulus was enhanced more significantly above the glass transition temperature. The barrier properties were enhanced by addition of mica before and after stretching. The Halpin‐Tsai theory underpredicted the relative modulus of the PET nanocomposites, whereas the Nielsen model over‐predicted the relative permeability. POLYM. ENG.

    Abstract: High density polyethylene (HDPE) is predominately processed from the molten state. However, there is the potential to enhance the mechanical properties by forming below the melt temperature, in the semi‐solid phase. To further investigate this enhancement, HDPE sheets were deformed under constant width, simultaneous equal‐biaxial (EB), and sequential biaxial deformation. The samples were deformed at strain‐rates, from 4 to 16 s −1 , up to nominal strains of 3.0 at temperatures below 130°C. The strain‐rate and high‐strain level applied were chosen so that the data was comparable to the thermoforming process. It was discovered that in order for the HDPE sheet to deform at the high‐rate and high strains the processing temperature must be between 126°C and 130°C. This resulted in a processing window that was particularly small, 5°C, and that within this window a temperature change of 1°C had a significant impact on the stress–strain response. The samples were analyzed post deformation, where the elastic modulus was found to increase by a factor of 2.08 in the machine direction, when deformed via EB at 129°C. The results showed that HDPE can be deformed to strain levels comparable to the thermoforming process. POLYM. ENG. SCI., 58:1516–1522, 2018. © 2017 Society of Plastics Engineers
