The urban environmental pollution is closely related to unilateral pursuit of economic growth, insufficient investment in urban environmental control, lack of environmental protection mechanism, etc . To promote urbanization, it is necessary to set up the development concept ecological cities and towns, establish scientific assessment mechanism for local governments, increase the investment in environmental control in villages and towns, optimize urban distribution, and achieve the coordinated development of urbanization and the environment.展开更多

One was a pre-adaption training with progressive intermittent hypoxia, with a constant lower pressure oxygen tank used in the plain before arriving at the plateau (PG). The other was by progressively increasing the time of exposure to hypoxia with oxygen supplied in stages after radical plateau (RG). By testing the blood oxygen saturation (SpO2), heart rate (HR), and quality of sleep after arriving at the 3800 m high plateau, results showed that the pre-acclimatization and radical groups performed better than the control group (CG). Both strategies were equivalent in terms of effects and principles in providing more flexible choices for acclimatization.展开更多

However, the microclimate and air quality must be well controlled so that they are not harmful to human health. This survey indicated that relative humidity is a common hygienic problem in underground space and buildings. Attention should be paid to humidity control and to the strengthening of routine ventilation at the construction stage. Carbon dioxide can be used as a hygiene index of air pollution; the sanitary standard for it in the air of underground buildings is 10%. The hygienic survey shows that the concentration of carbon dioxide is usually below this standard in the environments of underground space and buildings. (c)1989 Academic Press,Inc.展开更多

For developing countries, there is a de facto conflict between the right to development and the right to the environment, which leads to serious consequences. To coordinate development and the environment, developing countries should shift their pattern of development, take the path of sustainable development and realize environmental protection and ecological balance while promoting economic growth.展开更多

However, the disease may also be transmitted upon the interaction with the infected materials or surfaces in the environment. In this study, a deterministic model for bubonic plague disease with Yersinia pestis in the environment is developed and analyzed. Conditions for existence and stability of the equilibrium points are established. Using Jacobian method disease free equilibrium (DFE) point, E<sup>0</sup> was proved to be locally asymptotically stable. The Metzler matrix method was used to prove that the DFE was globally asymptotically stable when R<sub>0</sub> < 1. By applying Lyapunov stability theory and La Salles invariant principle, we prove that the endemic equilibrium point of system is globally asymptotically stable when R<sub>0</sub> > 1. Numerical simulations are done to verify the analytical predictions. The results show that bubonic plague can effectively be controlled or even be eradicated if efforts are made to ensure that there are effective and timely control strategies.展开更多

Because of the individual's speculative behaviors, the government's deviation from its environmental governance, and the non-cooperative game between individuals and the legal organization, the implementation of the compulsive institutions is not as good as being expected. Through analyzing the mechanism of the compulsive institutions, this paper puts forward some suggestions to enhance the efficiency of such institutions' implementation.展开更多

The natural nidi and epidemic areas of HFRS are distributed mainly in plain and hilly regions under 500 meters above the sea level; in plentiful-water zones and transitional zones; in temperate zone and subtropical zone of the eastern monsoon region; in the abundant-aluminum soil region and the sial soil region; in the eastern China damp forest region (agricultural districts and northeast forest districts); in the eastern Asia dampness-prefering animal geographic region. Apodemus agrarius and Rattus norvegicus are the thriving animal population, predominant species or common species as well as the main reservoir hosts and sources of infection in the natural nidi and epidemic areas of HFRS.展开更多
