Temperature effect on migration of Zn and Cd through natural clay
No full textTo investigate the effect of temperature on effective diffusion coefficients and retardation factors for Zn and Cd, combined diffusion and sequential extraction analyses were conducted at 15 degrees C and 55 degrees C. The effective diffusion coefficients of the metals increased up to ten times according to the increased temperature. On the other hand, the effect of temperature on the retardation factor depended on the retention mechanisms of the metals. The distribution coefficient for Zn, which was mainly partitioned in the carbonate phase, increased up to two times with the increase in temperature. On the other hand, the distribution coefficient for Cd, which was mainly partitioned in the exchangeable phase, was hardly affected by the temperature change. Results of combined diffusion and sequential extraction analysis showed that the effect of temperature on the heavy metals' (Zn and Cd) migration through the compacted natural clay was influenced by the combined effects of the diffusion coefficient and the retardation factor. Additionally, we could also observe the change in retention mechanism for the metals with the change in pore water concentration
Financial Crisis and Its Impact on the Economies of China and India
No full textThe study will focus on the current financial crisis and its impact on the growth, trade and employment in emerging market economies (EMEs) namely China and India. The emerging market economies are characterized as transitional, which means that they are in the process of moving from a closed to an open market economy. It is said that by adoption of neoliberal policies, the economy will suppose to lead to a better economic performance levels, as well as transparency and efficiency in the capital market.
The proponents of the ‘neoliberal economic policies’ always maintained that it is working and as a consequence, for example, the Indian economy is growing at high rates, the stock market is booming, foreign reserve is at a comfortably high level. The ‘free trade’ policy is making availability of a variety of goods unimaginable earlier as a mark of the benefits of globalization. The ‘invisible hand’ of the market, tries to pretend that market operates in isolation. On the basis most recent available data and studies the author has examined the impact of financial crisis on the economic growth and various sectors of the economies in China and India.
Finally, the author finds the argument that China emerging as the alterative engine of growth for the world economy is too ambitious. Some have suggested that a ‘decoupled Asia’ through its own growth and expanding domestic demands would ensure higher imports demands for its growing economies and thus limit the economic slowdown in the developed economies. But this is unlikely due to: the US, EU and Japan together account for more than half of China’s exports, and as recession deepens, it is bound to affect export sector and overall economic activity in China
Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
Portfolio of recorded performances and exegesis: Messiaen’s musical language for the jazz pianist - an exploration through performance.
No full textMoving beyond Gunther Schuller’s Third Stream amalgamation of classical and jazz, this study explores whether the musical language of Olivier Messiaen can make a valid contribution to jazz piano performance. Initially, my project sought to answer such questions as: What elements of the musical language of Messiaen already exist in the jazz vocabulary? Am I able to extend this further? What are the timbral structures and pianistic effects within Messiaen’s musical language? What will be the most effective application of Messiaen’s musical language to jazz piano performance? Endeavouring to answer the final question led me to consider such aspects as whether the project should be limited to quoting Messiaen motifs, arranging Messiaen melodies, replacing jazz harmonic structures on standards with examples from Messiaen’s musical language or whether it would be better to approach the research conceptually. The work of Hubert Nuss provided encouraging reassurance that this was not an impossible task. In order to articulate this conception, the initial challenge was to decide how the classical and jazz worlds might meet in a ‘Messiaen’ technique. The approach adopted was similar to that used for undergraduate jazz study, namely, immersion in the piano scores and recordings of Messiaen’s music as well as by live performances. This was followed by the development and assessment of a contrived approach when specific techniques, such as tonal colourings or harmonic structures, were developed through prepared exercises and consciously included in my performance. It was then compared with an intuitive approach when no such precise parameters were established. This submission consists of CD recordings of two public recitals and an exegesis. It documents the development of this Messiaen technique and discusses its application in my performances. It also demonstrates the ways that Messiaen’s musical language can be used within jazz piano performance to provide a colour that distinguishes jazz piano performance in a competitive field.Thesis (M.Mus.) -- University of Adelaide, Elder Conservatorium of Music, 201

The Political Economy of Development in Singapore
No full textSingapore has gone through a rapid transformation during the last forty-five years. From an entrepot predominantly towards commerce and services in the mid-1960s into an economy, which presently specialising in high value manufacturing activities, and regional financial hub for business services in East Asia. This paper aims to overview the issues of the role of state and foreign investment, which has played an important role in achieving rapid economic growth. For instance, in 2002 Singapore’s GDP was 24 times compared to 1965 levels. The average annual growth rate for GDP between 1965 and 2006 was nearly 8 % and GNP increased slightly higher over this period. The study examines the international environment and how it contributed to achieve higher rates of growth. It seems that these aspects are overlooked by the researchers. And with the end of the Cold War and with the recent surge in globalisation of production Singapore’s economy is being affected. The study will also argue that the historical factors seem to be important in determining a country’s development strategie

Comparison of the expression of cluster of differentiation (CD)39 and CD73 between propofol- and sevoflurane-based anaesthesia during open heart surgery
No full textHigh expression of cluster of differentiation (CD) 39 and CD73 has cardio-protective effects. We hypothesised that the expression of CD39 and CD73 would differ between propofol- and volatile anaesthetic-based anaesthesia in patients undergoing open heart surgery (OHS). The objective of this prospective randomized trial was to compare the changes in CD39 and CD73 levels in CD4(+) T cells between propofol-and sevoflurane-based anaesthesia during OHS. The study randomly allocated 156 patients undergoing OHS to a propofol or sevoflurane group. Blood was obtained preoperatively and up to 48 hours after weaning from cardiopulmonary bypass (CPB). The expression levels of CD39 and CD73 in circulating CD4(+) T cells, serum cytokines and other laboratory parameters were analysed. The primary outcome was the expression of CD39 and CD73 on CD4(+) T cells. Demographic data and perioperative haemodynamic changes did not show significant differences between the two groups. The expression of CD39 and CD73 in the sevoflurane group was significantly lower than in the propofol group (P < 0.001). Other laboratory findings including cardiac enzymes and cytokine levels, did not show significant intergroup differences. Propofol attenuated the decrease in CD39 and CD73 in circulating CD4(+) T cells compared to sevoflurane-based anaesthesia during OHS.Y
