A Cross-Cultural Study Of Intrusiveness And Fluency Effects Of Web Ads, Xinwei Wang, Tingru Cui, Hock Hai Teo
A Cross-Cultural Study Of Intrusiveness And Fluency Effects Of Web Ads, Xinwei Wang, Tingru Cui, Hock Hai Teo
Faculty of Engineering and Information Sciences - Papers: Part A
Advertising online has increasingly become an important marketing strategy. Along with the rising ad dollars invested on the web, marketers have also devised more powerful ad delivery tactics to garner online consumers' attention. These powerful online advertising tactics may result in intrusiveness perceptions and processing fluency effects. As Westerners tend to focus on the focal object whereas East Asians tend to pay attention to the focal object and contextual background simultaneously when processing a visual scene, East Asians' and Westerners' culturally divergent visual processing styles would lead them to develop varying intrusiveness perceptions and experience differential processing fluency when exposed …
A Novel Approach To Mineral Effects On Coke Reactivity, Brian Monaghan, Apsara Jayasekara, Raymond Longbottom
A Novel Approach To Mineral Effects On Coke Reactivity, Brian Monaghan, Apsara Jayasekara, Raymond Longbottom
Faculty of Engineering and Information Sciences - Papers: Part A
A coke analogue has been developed to evaluate mineral effects on coke reactivity. Elucidation of the effects of minerals on coke reactivity has proved difficult due to the complex and heterogeneous nature of industrial coke and the potential non-additive effects of minerals on coke reactivity. The coke analogue addresses this complexity and heterogeneity through control of its mineralogy, porosity and carbon structures. Recent studies have shown the analogue is capable of discriminating individual mineral effects on coke reactivity. In this paper the reaction mechanism of the analogues reactivity in CO2 is assessed and compared with that of industrial coke.

Effects Of Chemical Preservation On Flux And Solute Rejection By Reverse Osmosis Membranes, Kha L. Tu, Allan Chivas, Long D. Nghiem
Faculty of Engineering and Information Sciences - Papers: Part A
This study investigates the impacts of chemical preservation on the performance of polyamide reverse osmosis membranes with respect to water permeability and solute rejection. Three preservative chemicals, namely formaldehyde, sodium metabisulfite, and 2,2-Dibromo-3-Nitrilopropionamide, were evaluated for membrane preservation at pH 3 and 7. Experimental data show that chemical preservation may change the membrane surface properties, and consequently water permeability and solute rejection efficiency of the membrane are negatively impacted. The impacts of preservation on boron rejection and sodium rejection are similar in magnitude and more significant than those on water permeability. The results indicate that the impact of chemical preservation …
Effects Of Tungsten On The Hydrogen Embrittlement Behaviour Of Microalloyed Steels, Jingwei Zhao, Zhengyi Jiang, Chong Soo Lee
Effects Of Tungsten On The Hydrogen Embrittlement Behaviour Of Microalloyed Steels, Jingwei Zhao, Zhengyi Jiang, Chong Soo Lee
Faculty of Engineering and Information Sciences - Papers: Part A
The effects of tungsten (W) additions (0, 0.1, 0.5 and 1 wt.%) on the hydrogen embrittlement behaviour of microalloyed steels were systematically investigated by means of slow strain rate tests on circumferentially notched cylindrical specimens, and the mechanism of hydrogen-induced embrittlement was discussed. W addition is found to increase the activation energy of hydrogen desorption. Microstructural features affect the hydrogen embrittlement behaviour and fracture modes of microalloyed steels. It is suggested that the hydrogen-induced embrittlement in the studied microalloyed steels with different W additions is caused by the combined effects of decohesion and internal pressure in the presence of hydrogen.

Effects Of Hydrogen On The Critical Conditions For Dynamic Recrystallization Of Titanium Alloy During Hot Deformation, Jingwei Zhao, Hua Ding, Zhengyi Jiang, Dongbin Wei, Kezhi Linghu
Faculty of Engineering and Information Sciences - Papers: Part A
Hot deformation tests were performed to study the flow behavior and microstructural evolution of a Ti600 titanium alloy with different hydrogen contents. The effects of hydrogen on the critical conditions for the initiation of dynamic recrystallization (DRX) were investigated. The DRX kinetics models of hydrogenated Ti600 alloy were developed, and the DRX volume fractions were quantified under different deformation conditions. The results indicate that the addition of proper hydrogen (no greater than 0.3 pct) benefits the decrease of both the critical stress and critical strain for the initiation of DRX. The critical stress and critical strain are dependent linearly on …
Effects Of Temperature And Strain Rate On Microstructure And Mechanical Properties Of High Chromium Cast Iron/Low Carbon Steel Bimetal Prepared By Hot Diffusion-Compression Bonding, Xingjian Gao, Zhengyi Jiang, Dongbin Wei, Sihai Jiao, Dengfu Chen, Jianzhong Xu, Xiaoming Zhang, Dianyao Gong
Effects Of Temperature And Strain Rate On Microstructure And Mechanical Properties Of High Chromium Cast Iron/Low Carbon Steel Bimetal Prepared By Hot Diffusion-Compression Bonding, Xingjian Gao, Zhengyi Jiang, Dongbin Wei, Sihai Jiao, Dengfu Chen, Jianzhong Xu, Xiaoming Zhang, Dianyao Gong
Faculty of Engineering and Information Sciences - Papers: Part A
The objective of this study is to develop a hot diffusion-compression bonding process for cladding low carbon steel (LCS) to high chromium cast iron (HCCI) in solid-state. The influence of temperature (950-1150 degrees C) and strain rate (0.001-1 s (1)) on microstructure, hardness and bond strength of the HCCI/LCS bimetal were investigated. The interface microstructure reveals that the unbonded region can only be found for 950 degrees C due to lack of diffusion, while the intergrowth between the constituent metals occurred at and above 1100 degrees C. When bonding temperature increases to 1150 degrees C, a carbide-free zone was observed …

This study investigated effects of mature compost on gaseous emissions during composting using pig manure amended with corn stalks. Apart from a control treatment, three treatments were conducted with the addition of 5% (wet weight of raw materials) of mature compost: (a) mixing raw materials with mature compost at the beginning of composting; (b) covering raw materials with mature compost throughout the experimental period; and (c) covering raw materials with mature compost at the start of composting, but incorporating it into composting pile on day 6 of composting. Mature compost used for the last treatment was inoculated with 2% (wet …

Two metallurgical cokes were heat treated at 1673 K to 2273 K (1400 degrees celsius to 2000 degrees celsius) in a nitrogen atmosphere. The effect of heat treatment on the microstructure and microstrength of metallurgical cokes was characterized using X-ray diffraction, Raman spectroscopy, and ultramicroindentation. In the process of heat treatment, the microstructure of the metallurgical cokes transformed toward the graphite structure. Raman spectroscopy of reactive maceral-derived component (RMDC) and inert maceral-derived component (IMDC) indicated that the graphitisation degree of the RMDC was slightly lower than that of the IMDC in the original cokes; however graphitisation of the RMDC progressed …

Effects Of Mesh Size And Escape Gaps On Discarding In An Australian Giant Mud Crab (Scylla Serrata) Trap Fishery, Matt Broadhurst, Paul Butcher, Brian R. Cullis
Effects Of Mesh Size And Escape Gaps On Discarding In An Australian Giant Mud Crab (Scylla Serrata) Trap Fishery, Matt Broadhurst, Paul Butcher, Brian R. Cullis
Faculty of Engineering and Information Sciences - Papers: Part A
In response to concerns over excessive discarding from Australian recreational round traps (with four funnel entrances) used to target giant mud crabs, Scylla serrata, an experiment was done to assess the independent and cumulative utility of paired, bottom-located horizontal escape gaps (46x120 mm) and increasing mesh size (from 51 to 101 mm). Compared to conventional traps comprising 51-mm mesh throughout, those with the same mesh size and escape gaps caught significantly fewer (by 95%) undersize (- CL) crabs while maintaining legal catches. Traps made from 101-mm mesh (but with the same funnel entrances as conventional designs) and with and without …

The Effects Of Feed Solution Temperature On Pore Size And Trace Organic Contaminant Rejection By The Nanofiltration Membrane Nf270, Hai Quang Dang, William E. Price, Long Duc Nghiem
Faculty of Engineering and Information Sciences - Papers: Part A
This study investigated the effect of feed temperature on membrane pore size and the rejection of trace organic contaminants (TrOCs) by the nanofiltration (NF) membrane NF270. Filtration experiments were conducted using a cross flow membrane system at 20, 30 and 40 C. The membrane pore radius was estimated using the pore hindrance transport model at each temperature and the rejection data of three reference organic solutes (i.e. erythritol, xylose and glucose) experimentally obtained in this study. The results suggest that the pore size of an NF membrane is dependent on the feed solution temperature. An increase in the feed temperature …
