Ecological compensation based on willingness to accept for conservation of drinking water sources

Linyu XU,Bing YU,Yang LI

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 1,   Pages 58-65 doi: 10.1007/s11783-014-0688-3

Abstract: Ecological compensation is a powerful environmental economic tool for environmental protection in areas where drinking water sources are located. We established an ecological compensation accounting system based on respondents’ willingness to accept (WTA). In this system, stakeholder preferences and the factors that influence them can be gauged effectively using logit and tobit models. We applied this accounting system to ecological compensation for the Miyun Reservoir, Beijing, China. The average WTA value for Miyun Reservoir residents was approximately 1186 CNY per family in 2012, which could be set as a suitable compensation standard, since it is slightly higher than the local protection cost. Thus, the annual total ecological compensation could be 58.73 million CNY. Distance from the reservoir, job types, and attitude to environmental protection were variables with significant effects on WTA. In addition, trends for individual preferences were identified via an analysis of key influential factors. The results suggest some useful information for establishing ecological compensation mechanisms for conservation of drinking water sources. Suggestions include popularizing the concept and meaning of ecological compensation among residents, setting different compensation levels based on distance from the reservoir, considering the requirements of farmers, and taking various in-kind and out-of-kind compensation approaches.

Pollution survey of carbonyl compounds in train air

LU Hao, ZHU Lizhong

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 1,   Pages 125-128 doi: 10.1007/s11783-007-0023-3

Abstract: The train is an important vehicle in China, but its air quality has important impacts on passengers health. In this work, pollution from carbonyl compounds was measured in the air of six trains. The objectives of this work were to investigate carbonyl compound levels in selected air from trains, identify their emission sources, and assess the intake of carbonyl compounds for passengers. The methods for sampling and analyzing 10 carbonyl compounds such as formaldehyde, acetaldehyde, acrolein, acetone, propionaldehyde, crotonaldehyde, butyraldehyde, benzaldehyde, cyclohexanone, and valeraldehyde in indoor air were proposed with the sampling efficiency, recovery, and detection limit being 92% 100%, 91% 104%, and 0.26 0.82 ng/m, respectively. It was indicated that the total concentrations of carbonyl compounds were 0.159 0.2828 mg/m with the average concentration of 0.2330 mg/m. The average concentrations of formaldehyde, acetaldehyde and acetone were 0.0922, 0.0499, and 0.0580 mg/m, accounting for 42.6%, 21.4%, and 24.9% of the total concentrations of carbonyl compounds, respectively. The carbonyl compounds probably came from woodwork and cigarette smoking. The intake of carbonyl compounds for the passengers was approximately 0.043 0.076 mg/h. The carbonyl compounds in train air could be harmful to human health.

A survey of instantaneous poles for a class of two-degree-of-freedom spherical mechanisms

Soheil ZARKANDI

Frontiers of Mechanical Engineering 2014, Volume 9, Issue 4,   Pages 344-353 doi: 10.1007/s11465-014-0320-z

Abstract:

This paper is a detailed exploration of instantaneous poles for a class of two-degree-of-freedom (two-DOF) spherical mechanisms (SMs) with seven links or bars. For two-DOF SMs, the secondary instantaneous poles (the ones which cannot be found by direct inspection) must lie on the specified great circles. For many of these mechanisms, however, some of these great circles cannot be obtained by a direct application of Aronhold-Kennedy theorem. This paper presents geometrical and analytical techniques to locate these unknown great circles for three topologies of seven-bar two-DOF SMs.

A survey of physical activity among urban women in China

Shilin DENG MD, Tongyuan LIU,

Frontiers of Medicine 2009, Volume 3, Issue 4,   Pages 463-469 doi: 10.1007/s11684-009-0081-y

Abstract: Few studies have been conducted to assess the level of physical activity (PA) of women in China. The purpose of this study was to describe the prevalence of PA among women in Wuhan and explore sociodemographic and behavioral correlation to PA for the population. A total of 1359 community-dwelling women (42.9713.60 years old) participated in this study. The long-version IPAQ was used to define the level of PA. 45.7% of women were considered physically active, and 27.5% were vigorously active. The proportion of physical inactivity was around 26.8%. The total and 4 domains of PA showed significant age, education level, and occupation variation. PA tended to be lower as the age declined. PA in transportation, housework, leisure time, and the total tended to be the lowest or the second lowest among the women aged 18–35 years old. PA tended to be lower as the level of education increased. Among the 5 indices, PAwas the lowest among women with college education, especially those with postgraduate education. PA tended to be the lowest among the women of office staff and instructor or technician. Generally, the total and 4 domains of PA showed significant age, education level, and occupation variation. Physical inactivity appears to be more common among younger women, or college-educated women, office ladies, and female instructor and technicians.

A survey of decorative materials on the energy consumption of mid-rise residential buildings in Mashad

Masoud Taheri SHAHRAEIN, Lihua ZHAO, Qinglin MENG

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 4,   Pages 490-497 doi: 10.1007/s11709-010-0068-4

Abstract: Polyvinylchloride (PVC) panel is one of the most favorite decorative materials that has been popularly applied as finishing of ceiling in residential buildings. It is about five years that the people incline to redecorate the ceiling of old buildings with PVC panel in big cities of Iran, such as Mashad. In this study, the influence of ceiling PVC panel on the cooling and heating loads of studied apartment were determined by software DeST-h. In addition, the summer natural ventilation of the mentioned apartment is investigated by determining the wind speed into the apartment through the computational fluid dynamics (CFD) software. The evaluation of environment indoor wind velocity showed that most of the apartment space is a comfortable zone. The results of studied building analyses demonstrated that using PVC panel on the ceiling can decline the energy consumption of the penthouse (fifth level) of the investigated building, which is about 3.7% and 7% for studied methods of without and with air layer, respectively. In addition, although the existence of air layer can decline the cooling and heating loads, the increase in air layer thickness did not show significant decrease on building energy consumption. However, the PVC panel is expensive and is not suitable to be used for ceiling thermal insulation, but adding a thin layer of air between ceiling and PVC panel can be a good step toward sustainable building, when the people are inclined to utilize it as a decorative ceiling.

Jun BI, Yongliang ZHANG, Bing ZHANG,

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 3,   Pages 361-372 doi: 10.1007/s11783-010-0017-4

Abstract: In developing countries, there is controversy over the correct perception regarding environmental and developmental issues. Few studies have examined the perception of low-income nationals in regards to social and environmental issues. This paper looks at the relationship between socio-demographic factors and the groups’ perceived priority regarding environmental and social issues in Wujin County. The results indicated that most residents, specifically the young, government employed and the urban community consider environmental issues to be serious, especially in relation to air pollution and water pollution. Furthermore, many residents feel it is important to rank environmental problems that are related to other social and economic issues, and that environmental protection must be set as a priority in Wujin County. Compared to social issues, environmental concern was greater among the young, government employed, and the urban community, because of their higher education and affluence. In addition, 66.2% of residents consider environmental protection to be more important than economic development. Thus, environmental protection must be set as a high priority in Wujin County, in order to face the many social and environmental challenges inherent in development.
