But such kind of evaluation system has not been proposed in China. In this study, an evaluation index system is specifically developed to evaluate deep groundwater management efficiency. It is composed of three first-level indicators(law enforcement capability, management ability, and management effectiveness) and eleven second-level indicators. The second-level indicators include seven mandatory indicators and four optional indicators. Piecewise linear function is used to normalize the quantitative indicators, and expert scoring method and questionnaire survey method are used to normalize the qualitative indicators. Then a comprehensive indicator weighting evaluation method is used to evaluate the first-level indicators and the target topic. A case study is carried out to evaluate deep groundwater management efficiency in Tianjin City. According to the evaluation score in each period, the management efficiency of every district in Tianjin City gradually improved. The overall evaluation score in the early deep groundwater extraction period is 0.12. After a series of deep groundwater protection efforts, this score reached to 0.61 in 2007, and met the regulation criteria. The evaluation results also showed that the further groundwater management efforts in Tianjin City should be focused on building a dynamic database to collect comprehensive deep well-log data; and on a reasonable design and distribution of the groundwater monitoring network. It demonstrated that the index system is suitable to locate the deficiencies of current groundwater management systems and to guide further improvements. It can then be used to protect deep groundwater.展开更多

MethodsThe questionnaire consisting of prevalence, awareness rate, management rate, behavior correct rate, control rate, and medicine obey was used to survey the chronic disease condition in 2009. A total of 809 736 residents were randomly selected from Shanghai and Guangdong, China. ResultsThe hypertension prevalence was 17.81%. From sex analysis, the female has higher rate than male in hypertension prevalence, understand rate, management rate, behavior correct rate, control rate, and medicine obey rate. From age analysis, the prevalence, understand rate, management rate, control rate, and medicine obey were increasing along with the age, but behavior correct rate was not in this condition. The diabetes prevalence was 6.92%. To compare with Shanghai and Guangzhou in 5 aspects, the prevalence of chronic diseases was alike. Except lower behavior correct rate in Shanghai, management rate, behavior correct rate, control rate, and medicine obey rate were higher in Shanghai. ConclusionThe government must take main principle in chronic disease control. Base construction of community health management and increase management level of chronic diseases should be enhanced and practitioner's knowledge of chronic disease management should also be enhanced.展开更多

While efforts to identify and limit point source inputs of P to surface waters have seen some success, nonpoint sources remain difficult to identify, target, and remediate. As further improvements in wastewater treatment technologies becomes increasingly costly, attention has focused more on nonpoint source reduction, particularly the role of agriculture. This attention was heightened over the last 10 to 20 years by a number of highly visible cases of nutrient-related water quality degradation; including the Lake Taihu, Baltic Sea, Chesapeake Bay, and Gulf of Mexico. Thus, there has been a shift to targeted management of critical sources of P loss. In both the U.S. and China, there has been an intensification of agricultural production systems in certain areas concentrate large amounts of nutrients in excess of local crop and forage needs, which has increased the potential for P loss from these areas. To address this, innovative technologies are emerging that recycle water P back to land as fertilizer. For example, in the watershed of Lake Taihu, China one of the largest surface fresh waters for drinking water supply in China, local governments have encouraged innovation and various technical trials to harvest harmful algal blooms and use them for bio-gas, agricultural fertilizers, and biofuel production. In any country, however, the economics of remediation will remain a key limitation to substantial changes in agricultural production.展开更多

An overview of recent progress in PEM fuel cell modeling has been provided. Fundamental transport phenomena in PEM fuel cells and the corresponding mathematical formulation of macroscale models are analyzed. Various important issues in PEM fuel cell modeling and simulation are examined in detail, including fluid flow and species transport, electron and proton transport, heat transfer and thermal management, liquid water transport and water management, transient response behaviors, and cold-start processes. Key areas for further improvements have also been discussed.展开更多

Is the healthy business environment a fiction or a real opportunity？ How far-reaching are the roots of the future natural processes of changes？ How to work with the current global economic models？ Can the current European integration process be considered as natural？ Is a weak state a new opportunity for a future strong economy？ What is the historical essence of the liberal thought？ Why the current economic models are not permanent, why are they not sustainable, and why are they not developing for the basic quantum, which is the man as an individual？ Can also the basic quantum be integration units as family, society, company, municipality, region, country, or EU, etc.？ Qualified answers to the questions can be seen in a theoretical context of the General Theory of the Sustainable Development （GTSD）, too. Theoretical trinity of GTSD is based on three theoretical pillars： GPT （Gravitation Polarity Theory）, QET （Quantum Economy Theory）, and BIT （Big Integration Theory）. They can be considered as relevant theoretical basics for historical, current, and future sustainable development process. The healthy business environment is based on the healing of man. In GTSD, businessman and man gain a new source of knowledge, a new natural relationship, and a new content. This is a responsibility towards the customer and towards the pa^ner in business. Businessman＇s profit speaks about a new business in natural partnerships. Sustainable development without the Groove Management （second generation management） and without the fourth Reformation （with second generation of innovation） is a process that only reflects the regressive trend that takes place for more than 6000 years. Without the new content of the Fifth Theoretical Dimension （Consciousness） the historical mainstream of sustainable development process cannot be grasped. The biggest risk for the expected Healthy business society is a contemporary slave communism and contemporary crazy capitalism. Feasibility of business models of healthy business doing societies stands not only on adequate theoretical basis, but also on predicted cannibalism between slave communism and crazy capitalism. The biggest current risk of healthy business environment is a political arbitrariness, the desire for power, and the desire for money----corruption.展开更多

However, uncertainty regarding travel time decreases the quality of service and leads end-users to change their routes and schedules even when the average travel time is low, Indicators describing travel time reliability are being developed and should be used in the future both for the optimization and the assessment of active traffic management operation. This paper describes a managed lane experience on a motorway weaving section in France - hard shoulder running operation in rush hours. The paper is focused on travel time reliability indicators and their use for reliability assessment. It provides some discussions about the advantages and drawbacks of reliability indicators under different traffic conditions. It particularly shows the difference between using buffer times and buffer indexes. The paper also discusses the difficulty of interpreting the skew of travel time distribution for travel reliability,展开更多
