China and East Asian Energy - Prospects and Issues Volume II Part I

This collection of papers in two volumes is the second in a series on China and East Asian Energy, a major project which is an initiative of the East Asia Forum in conjunction with the China Economy and Business Program in the Crawford School of Economics and Government at the Australian National University (ANU). The first volume was published in April 2007. The research program is directed at understanding the factors influencing Chinas energy markets. It also involves high-level training and capacity building to foster long-term links between policy thinkers in China and Australia. It provides for regular dialogue with participants from the energy and policy sectors in the major markets in East Asia and Australia. The backbone of the dialogue is an annual conference, the location of which has thus far alternated between Beijing and Canberra. The objective is to advance a research agenda that informs and influences the energy policy discussion in China, Australia and the region. This special edition of the Asia Pacific Economic Papers brings together papers presented at the second conference in the series. Due to their number and length, papers from that second conference are published across two volumes of the Asia Pacific Economic Papers. This volume includes the first half of the papers, while the next volume includes the second half. The third conference in the project is scheduled for July 2008.China, Energy, East Asia

China and East Asian Energy : Prospects and Issues

In October 2005, the Crawford School (then the Asia Pacific School of Economics and Government) within the Australian National University (ANU) initiated a major research project on China and East Asian Energy. The project is being undertaken under the schools East Asia Forum in conjunction with the China Economy and Business Program. The first conference in the series being organised under the auspices of the China and East Asian Energy Strategies Research Program was hosted in Beijing by the Energy Research Institute and the ANU on 1011 October 2005. It was the first of five annual conferences in the program. This book brings together the key papers presented at that conference.

Optimal load scheduling of household appliances considering consumer preferences : an experimental analysis

Abstract: This paper discusses an experimental study of the home appliances scheduling problem that incorporates realistic aspects. The residential load scheduling problem is solved while considering consumer’s preferences. The objective function minimizes the weighted sum of electricity cost by earning relevant incentives, and the scheduling inconvenience. The objective of this study is five-fold. First, it sought to develop and solve a binary integer linear programming optimization model for the problem. Second, it examined the factors that might affect the obtained schedule of residential loads. Third, it aimed to test the performance of a developed optimization model under different experimental scenarios. Fourth, it proposes a conceptual definition of a new parameter in the problem, the so-called “flexibility ratio”. Finally, it adds a data set for use in the literature on the home appliance scheduling problem, which can be used to test the performance of newly-developed approaches to the solution of this problem. This paper presents the results of experimental analysis using four factors: problem size, flexibility ratio, time slot length and the objective function weighting factor. The experimental results show the main and interaction effects, where these exist, on three performance measures: the electricity cost, inconvenience and the optimization model computation time

Multi-objective analysis of the co-mitigation of CO2 and PM2.5 pollution by China's iron and steel industry

China has experienced serious fine particulate matter (PM2.5) pollution in recent years, and carbon dioxide (CO2) emissions must be controlled so that China can keep its pledge to reduce CO2 emissions by 2030. The iron and steel industry is energy intensive and contributes significantly to PM2.5 pollution in China. The simultaneous reduction of CO2 emissions and PM2.5 pollution while minimizing the total mitigation costs remains a crucial issue that must be resolved. Using a multi-objective analysis, we compared potential technology combinations based on various policy preferences and targets. Our results showed that policies designed to mitigate PM2.5 pollution have substantial co-benefits for CO2 emissions reductions. However, policies focused solely on reducing CO2 emissions fail to effectively reduce PM2.5. Furthermore, CO2 emissions reductions correspond to large financial costs, whereas PM2.5 pollution reductions are less expensive. Our results suggest that under limited budgets, decision makers should prioritize PM2.5 reductions because CO2 reductions may be simultaneously achieved. Achieving large decreases in CO2 emissions will require further technological innovations to reduce the cost threshold. Thus, China should focus on reducing PM pollution in the short term and prepare for the expected challenges associated with CO2 reductions in the future

Rapid label-free identification of mixed bacterial infections by surface plasmon resonance

<p>Abstract</p> <p>Background</p> <p>Early detection of mixed aerobic-anaerobic infection has been a challenge in clinical practice due to the phenotypic changes in complex environments. Surface plasmon resonance (SPR) biosensor is widely used to detect DNA-DNA interaction and offers a sensitive and label-free approach in DNA research.</p> <p>Methods</p> <p>In this study, we developed a single-stranded DNA (ssDNA) amplification technique and modified the traditional SPR detection system for rapid and simultaneous detection of mixed infections of four pathogenic microorganisms (<it>Pseudomonas aeruginosa</it>, <it>Staphylococcus aureus</it>, <it>Clostridium tetani </it>and <it>Clostridium perfringens</it>).</p> <p>Results</p> <p>We constructed the circulation detection well to increase the sensitivity and the tandem probe arrays to reduce the non-specific hybridization. The use of 16S rDNA universal primers ensured the amplification of four target nucleic acid sequences simultaneously, and further electrophoresis and sequencing confirmed the high efficiency of this amplification method. No significant signals were detected during the single-base mismatch or non-specific probe hybridization (<it>P </it>< 0.05). The calibration curves of amplification products of four bacteria had good linearity from 0.1 nM to 100 nM, with all R²values of >0.99. The lowest detection limits were 0.03 nM for <it>P. aeruginosa</it>, 0.02 nM for <it>S. aureus</it>, 0.01 nM for <it>C. tetani </it>and 0.02 nM for <it>C. perfringens</it>. The SPR biosensor had the same detection rate as the traditional culture method (<it>P </it>< 0.05). In addition, the quantification of PCR products can be completed within 15 min, and excellent regeneration greatly reduces the cost for detection.</p> <p>Conclusions</p> <p>Our method can rapidly and accurately identify the mixed aerobic-anaerobic infection, providing a reliable alternative to bacterial culture for rapid bacteria detection.</p

The cosmic ray test of MRPCs for the BESIII ETOF upgrade

In order to improve the particle identification capability of the Beijing Spectrometer III (BESIII),t is proposed to upgrade the current endcap time-of-flight (ETOF) detector with multi-gap resistive plate chamber (MRPC) technology. Aiming at extending ETOF overall time resolution better than 100ps, the whole system including MRPC detectors, new-designed Front End Electronics (FEE), CLOCK module, fast control boards and time to digital modules (TDIG), was built up and operated online 3 months under the cosmic ray. The main purposes of cosmic ray test are checking the detectors' construction quality, testing the joint operation of all instruments and guaranteeing the performance of the system. The results imply MRPC time resolution better than 100$ps$, efficiency is about 98$\%$ and the noise rate of strip is lower than 1$Hz/$($scm^{2}$) at normal threshold range, the details are discussed and analyzed specifically in this paper. The test indicates that the whole ETOF system would work well and satisfy the requirements of upgrade
