Effects of design parameters on rooftop photovoltaic economics in the urban environment: a case study

Hongying ZHAO, Rebecca YANG, Chaohong WANG, W. M. Pabasara U. WIJERATNE, Chengyang LIU, Xiaolong XUE, Nishara ABDEEN

Frontiers of Engineering Management 2019, Volume 6, Issue 3,   Pages 351-367 doi: 10.1007/s42524-019-0023-6

Abstract: Many researchers found high potential of adopting building photovoltaic (PV) systems in urban areas, especially on building rooftop, to improve the sustainability of urban environment. However, the optimal energy output performance and economic benefit of the PV system are affected by the usable roof area, PV array layout, and shading effect considering high city density. This study aims to understand the effects of these design parameters in the urban environment of rooftop PV’s economic performance. This study carries out a case study in the urban area of Melbourne with 90 PV designs under three shading conditions to generate 270 scenarios. Through a lifecycle cost-benefit analysis, including net present value (NPV), NPV per kW, internal return rate (IRR), and payback year, the results can help in developing a comprehensive understanding of the economic performance of rooftop PV designs that cover most of the urban areas of Melbourne. The optimal PV design scenarios for the urban environment are identified, thereby providing investors and industry professionals with useful information on value-for-money PV design. Meanwhile, the maximum shading loss that makes the PV systems financially unfeasible is investigated, and design scenarios with greatest ability to sustain the shading effect are identified. This research can also support the policy makers’ decision on the development and deployment of the roof PV systems in urban planning.

Comparative cost analysis of three different anesthesia methods in gynecological laparoscopic surgery

Xiaohui Chi, Yeling Chen, Mingfeng Liao, Fei Cao, Yuke Tian, Xueren Wang

Frontiers of Medicine 2012, Volume 6, Issue 3,   Pages 311-316 doi: 10.1007/s11684-012-0205-7

Abstract:

In the current study, we assessed and evaluated the costs and benefits of three popular methods of general anesthesia practiced in our department for gynecological laparoscopic surgery in recent years. Sixty adult female patients who underwent elective gynecological laparoscopic surgery under general anesthesia were randomly divided into three groups: group V, group I and group C. In group V, anesthesia was induced intravenously with midazolam, remifentanil, propofol and vecuronium, and maintained with continuous infusion of propofol and remifentanil. In group I, anesthesia was intravenously induced with midazolam, fentanyl, propofol and vecuronium, and maintained with inhaled isoflurane and intravenous bonus of fentanyl. In group C, anesthesia was induced as in group I, but maintained with isoflurane inhalation combined with propofol-remifentanil infusion. All patients received vecuronium for muscle relaxation. Perioperative incidences of complications and total anesthesia costs for patients in all groups were recorded. In addition, postoperative satisfaction of the patients was also noted, and similar outcomes of the satisfaction were reported in all 60 patients. Although there was no statistical significance among groups, the incidence of postoperative nausea and vomiting were higher in group C, and the rates of shivering and the needs for analgesics were higher in group V. Anesthesia costs in group I were the lowest. Therefore, it is concluded that the costs of anesthesia induced with midazolam, fentanyl, propofol, vecuronium, and maintained with isoflurane, fentanyl and vecuronium are cheapest, and there is no significant difference in patients’ satisfaction and safety among the three above-mentioned methods of anesthesia in our department.

Circular economy：ideas and innovation

Jin Yong,Feng Zhijun,Chen Dingjiang

Strategic Study of Chinese Academy of Engineering 2010, Volume 12, Issue 1,   Pages 4-11

Abstract:

It has been over a decade since China paid close attention to the concept of circular economy. During this period the country made promoting circular economy as one of the basic national development strategies. There are many ideas and theories which have been brought forward and explored by experts and researchers from multi disciplines. As a connecting link between the preceding and the following, this paper summarizes and comments one of those most important ideas and theories, which could be used as general guidelines for innovation to boost the circular economy.

Methodological considerations for redesigning sustainable cropping systems: the value of data-mining large and detailed farm data sets at the cropping system level

Nicolas MUNIER-JOLAIN, Martin LECHENET

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 1,   Pages 21-27 doi: 10.15302/J-FASE-2019292

Abstract:

Redesigning cropping and farming systems to enhance their sustainability is mainly addressed in scientific studies using experimental and modeling approaches. Large data sets collected from real farms allow for the development of innovative methods to produce generic knowledge. Data mining methods allow for the diversity of systems to be considered holistically and can take into account the diversity of production contexts to produce site-specific results. Based on the very few known studies using such methods to analyze the crop management strategies affecting pesticide use and their effect on farm performance, we advocate further investment in the development of large data sets that can support future research programs on farming system design.

Development and technical progress in large-scale circulating fluidized bed boiler in China

Zhong HUANG, Lei DENG, Defu CHE

Frontiers in Energy 2020, Volume 14, Issue 4,   Pages 699-714 doi: 10.1007/s11708-020-0666-3

Abstract: Circulating fluidized bed (CFB) boilers has realized the clean and efficient utilization of inferior coal like gangue and coal slime, high sulfur coal, anthracite, petroleum coke, oil shale and other resources. As a country with the largest amount of CFB boilers and the largest installed capacity in the world, China has 440 100–600 MW CFB boilers with a total capacity of 82.29 GW , including 227 units of 135 MW , 95 units of 300 MW , and 24 supercritical units. The statistics of typical 100–300 MW CFB boilers showed that the average number of unplanned shut-down was only 0.37 times per year, among which the 135 MW was 0.26 times per year and 300 MW was 0.46 times per year. The auxiliary power ratio of some 300 MW CFB boilers based on flow-pattern reconstruction can be reduced to about 4%, which is closed to the same level of pulverized coal (PC) boilers. This paper summarizes the development process and application status of China’s large-scale CFB boilers, analyzes the characteristics and technical performance of the iconic units, and introduces solutions to the problems such as water wall wear and bottom ash cooling.

Insights into Current Severe Problems with China’s Nursing System, and Construction Strategies

Pi Hongyin,Meng Wenwen,Zhang Jie,Zhi Chen and Zhao Ting

Strategic Study of Chinese Academy of Engineering 2017, Volume 19, Issue 2,   Pages 79-83 doi: 10.15302/J-SSCAE-2017.02.013

Abstract:

Based on a literature review, a questionnaire survey, and expert consultation, this paper provides insights into the severe problems that exist within China’s nursing system; analyzes these problems in terms of the allocation of nursing human resources, the development and construction of the nursing discipline, and nursing value realization; and sets forth countermeasures and suggestions. According to the analysis results, problems exist regarding the allocation of nursing human resources in China, and include the number of nurses, the educational background of nurses, the age structure of nurses, and the stability of the nurse workforce. Professional curriculum design, professional training modes, and financing investments reveal severe problems for the development and construction of the nursing discipline. Nursing services are low priced, nursing income is low, and the value of nursing is underestimated; these circumstances are key problems that hinder the development of the nursing profession. In view of these severe problems, this paper puts forward countermeasures and suggestions for strengthening nursing team building, improving the quality of nursing services, accelerating nursing discipline construction and professional training, refining the pricing of nursing, and raising nurse treatment and construction strategies, with a view toward providing a basis for building a new nursing system.
