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.

An introduction to the medicinal plant genome project

Shilin Chen, Li Xiang, Xu Guo, Qiushi Li

Frontiers of Medicine 2011, Volume 5, Issue 2,   Pages 178-184 doi: 10.1007/s11684-011-0131-0

Abstract: In recent years, genomics has developed rapidly with the application of next-generation sequencing technology. However, very few studies have been carried out on genomics for medicinal plants. This paper introduces the genome research of medicinal plants, including genome sequencing, assembly, annotation, and functional genomics, to set up the foundation for the development of natural medicines and the selection of cultivars with good agricultural traits. This study places the study on traditional Chinese medicine into the frontier field of life science.

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.
