The number of cars is increasing rapidly in most cities around the world including those in China. Access to a car increases the range of opportunities available and confers status. The construction of cars can also be a major contributor to a national economy and provide many jobs. However, mass car ownership brings many problems including environmental damage, resource depletion, congestion and inequality. In this paper the nature of urban transport problems in general is examined, and then the extent to which these are applicable in Chinese cities is considered. Then the future of transport in such cities is considered using some projections by the World Bank. It is shown that the problems will become much worse if no policy intervention occurs, but even with significant investment, the quality of the environment will deteriorate.

AbstractThis paper gives H-O type grid generation and applies finite-volume method forwing-body flow.A 3-D Euler code for wing-body has been developed. We improve in thiscode the distribution of the number of grid points over wing and body surfaces,and keepthe training edge of the wing being one of the grid lines even when the edge has sweepbackor sweep *** code developed can provide not only the spanwise pressure distribu-tion as usual ou cross-flow planes,but also the chordwise Pressure *** com-putation for NASA TN D-712 wing-body model with the present code shows that thecomputed pressure distributions are in very good agreement with the experiment.

This contribution presents a magnetron sputter deposition tool with broadband optical monitor and online re-optimization capability for high volume production. The layer termination relies on a comparison of the actually measured reflection spectrum with a pre-calculated target spectrum. Spectra recorded after each deposited layer are analyzed by the re-optimization module and in case of significant deviations layer thicknesses and target spectra for the remaining layers are recalculated. This technique significantly improves the performance and reproducibility in case of highly denlanding coating designs and is able to correct abnormal production errors in individual layers, which will lead to coating failure without re- optimization.

A simple optical technique based on fluctuations in light transmitted through flowing suspensions has proved useful in two distinct water treatment applications. The first of these is the monitoring and control of coagulation/flocculation processes, where information on optimum coagulant dosages as well as on the dynamics of floc formation can be derived. The method is suitable for a very wide range of particle concentrations, up to levels found in highly turbid river waters. The second application is as a very sensitive monitor of particles in filtered water. Such monitoring can help to ensure the effective removal of pathogens such as Cryptosporidium from drinking water. Brief accounts of these techniques are given, together with some examples of their use.

The purpose of this paper is to show how activating perception, imagery and creativity facilitate the mastery of specific skills of visual arts education. Specifically, the study aimed at answering two questions: How can teachers enhance visual and creative expression; and What criteria should be used to evaluate specific learning of visual arts skills Based on a literature review on visual language two specific exercises were devised: one concerning the elaboration and meaning attribution of an image and the other the illustration of a concept. The two exercises were applied to 100 13-year-old students of a rural community in Portugal. The exercises were evaluated in terms of fluency, flexibility, originality, elaboration, expressiveness and adequateness. The results reveal statistically significant differences in these dimensions after the completion of second exercise, revealing that it is possible to use elements of the visual code to express ideas in creative ways.

Flood Risk Mitigation in the Tisza Valley by Deep Floodplain Reservoirs： The Effect on the Land Use

Journal of Environmental Science and Engineering(A) 2012年第1期1卷 34-40页

作者： Zs6fia Derts Laiszlo Koncsos Department of Sanitary and Environmental Engineering Budapest University of Technology and EconomicsBMEBudapest H-｜111．Hungary

The actual situation of the Tisza Valley traditionally used for land farming is basically determined by the consequences of the river regulation of the nineteenth century which aimed at the extension of the intensive agriculture, by the extreme water regime of alternating periods of flood showing a deteriorating trend and drought related to the climatic change; and by several environmental problems induced mainly by the land use. The objective of the article is to prove the regional advantages of a proposed technical solution to mitigate the flood risk with a special regard to the land cover. Hydrodynamic modeling results prove that the best technical solution is given by a combination of different strategies containing the inundation of deep floodplains-areas regularly covered by water before the river regulation works and, globally, by an important mitigation of flood damages, the costs of solution would be surely covered in the longterm. By means of its natural-resembling operation, the regular water cover would allow a multiple use of water, contributing to the solution of the simultaneously existing aridity problem, and, the development of the floodplain landscape management would help improve the ecological and the economical upgrading of the region.
