Microenvironmental time-activity patterns in Chongqing, China

Yu ZHAO, Shuxiao WANG, Gangcai CHEN, Fei WANG, Kristin AUNAN, Jiming HAO

《环境科学与工程前沿（英文）》 2009年第3卷第2期页码 200-209 doi: 10.1007/s11783-009-0010-y

摘要： An investigation using recall questionnaires was conducted in winter and autumn 2006 to evaluate the time-activity patterns in Chongqing, China. The average time spent in seven microenvironments (MEs) including outdoors, transit, living room, bedroom, kitchen, classroom/office, and other indoors were found to be about 3.5, 1.1, 2.5, 9.7, 1.4, 4.2, and 1.7 h per day, respectively. According to the results of a nonparametric test, the sampling period and day of week were significant for the variation of the time spent in all MEs except for transit and outdoors. The time budget was analyzed using a general linear model (GLM), which exhibited significant variability by demographic factors such as gender, age, residence, education, and household income.

Design concept of the Twin River Bridges in Chongqing, China

Man-Chung TANG

《结构与土木工程前沿（英文）》 2011年第5卷第4期页码 427-431 doi: 10.1007/s11709-011-0134-6

摘要： The Dongshuimen Bridge over the Yangtze River and the Qiansimen Bridge over the Jialing River in Chongqing, China are located at the tip of the Yuzhong Peninsula. Together, they are called the Twin River Bridges. Both are double deck structures carrying four lanes of traffic on their upper decks and two transit tracks on their lower decks. The girders are steel truss structures with orthotropic plates and the towers are made of concrete. Aesthetics were carefully considered for the design of these bridges because of their visibility in the city and their neighboring landmarks.

CuAlCl

Yixiu WANG,Chao LI,Fanchao MENG,Shuling LV,Jintao GUO,Xiaoqin LIU,Chongqing WANG,Zhengfei MA

《化学科学与工程前沿（英文）》 2014年第8卷第3期页码 340-345 doi: 10.1007/s11705-014-1438-6

摘要： A CuAlCl doped metal organic framework, CuAlCl @MIL-101, was prepared by introducing CuAlCl into the pores of MIL-101 for the selective adsorption of CO over N . The CuAlCl molecules were evenly distributed into various pores sizes and did not change the intrinsic structure of the MIL-101. Isotherms for CO and N adsorption at 298 K showed that the CO capacity on CuAlCl @MIL-101 was much higher than that on virgin MIL-101, whereas the N capacity decreased. The selectivity for CO over N improved from 4.64 to 31.5 at 298 K and 1 bar. The CuAlCl @MIL-101 adsorbent displayed outstanding CO adsorption stability and the adsorbent could be regenerated by applying a simple vacuum of 4 mmHg.

Life cycle analysis and choice of natural gas-based automotive alternative fuels in Chongqing Municipality

WU Rui, LI Guangyi, ZHANG Zongyi, REN Yulong, HAN Weijian

《环境科学与工程前沿（英文）》 2007年第1卷第3期页码 292-298 doi: 10.1007/s11783-007-0049-6

摘要： Road transport produces significant amounts of emissions by using crude oil as the primary energy source. A reduction of emissions can be achieved by implementing alternative fuel chains. The objective of this study is to carry out an economic, environmental and energy (EEE) life cycle study on natural gas-based automotive fuels with conventional gasoline in an abundant region of China. A set of indices of four fuels/vehicle systems on the basis of life cycle are assessed in terms of impact of EEE, in which natural gas produces compressed natural gas (CNG), methanol, dimethylether (DME) and Fischer Tropsch diesel (FTD). The study included fuel production, vehicle production, vehicle operation, infrastructure and vehicle end of life as a system for each fuel/vehicle system. A generic gasoline fueled car is used as a baseline. Data have been reviewed and modified based on the best knowledge available to Chongqing local sources. Results indicated that when we could not change electric and hydrogen fuel cell vehicles into commercial vehicles on a large scale, direct use of CNG in a dedicated or bi-fuel vehicle is an economical choice for the region which is most energy efficient and more environmental friendly. The study can be used to support decisions on how natural gas resources can best be utilized as a fuel/energy resource for automobiles, and what issues need to be resolved in Chongqing. The models and approaches for this study can be applied to other regions of China as long as all the assumptions are well defined and modified to find a substitute automotive energy source and establish an energy policy in a specific region.

摘要： After the establishment of big reservoirs, the environment along the Yangtze River, China, has changed. The alterations may influence people’s health. This study intended to find out the relationships between the environmental changes and the incidence of hemorrhagic fever with renal syndrome (HFRS) in the Big Three Gorges Area (BTGA) of Chongqing Municipality, China. Land-use thematic maps were applied in the research. The results show that there was a significant relationship between the land-use change in the grass area and the cumulative HFRS incidence (correlation coefficient= − 0.676, = 0.011). In the BTGA, the land was submerged because water filled in the reservoir, and meanwhile, the government called for returning land for farming to forestry. It is concluded that the changes of environment may influence the incidence of HFRS.

《中国工程科学》 2014年第16卷第5期页码 110-112

摘要：

2012—2013年根据国家卫生和计划生育委员会发布的《计划生育手术并发症鉴定管理办法（试行）》和《计划生育手术并发症鉴定分级标准（试行）》，通过填写重庆市统一的计划生育手术并发症鉴定申请表，对重庆市部分区（县）进行了计划生育手术并发症鉴定，并对市级鉴定情况进行了探讨。结果表明：2012—2013 年申请男性绝育术后并发症市级鉴定的56 例中，符合男性绝育术后并发症的有10 例，占申请人数的25.2 %；自述症状中有25 例与男性绝育术后并发症无关，占44.64 %；符合男性绝育术后并发症的都是20 世纪90 年代以前进行的绝育术。因此，男性绝育术后并发症鉴定应严格执行鉴定标准，做到公平、公开、公正，应做好男性绝育术相关知识的宣传，加强对老年病科普知识的宣传，并加强计划生育技术服务队伍的建设。
