The challenge of the municipality is to prepare to have its territory fully transformed. This study aimed to establish quantitative data on the interferences that the growth model practiced has caused in its main watercourse called Val?o dos Bois. For this, its morphometric characteristics and physicochemical parameters of water quality were measured, and computational simulations of the self-purification processes were performed at various points, as well as the infiltration and precipitation processes, surface flow and leaching in four occupation scenarios of the urbanized areas of the basin, for rains with five different return periods.展开更多

So, population radiophobia can be overcome. That type of reactors can be simultaneously more safely and more cheaply. As all other coolants, LBE and lead coolant (LC) possess the certain virtues and shortcomings. The presented report includes the comparative analysis of characteristic properties of those coolants, their impact on reactor safety, reliability and operating characteristics. The conclusion is made about promising usage of FRs with these coolants in future NP after the experience in operating of the prototypes of such reactors has been obtained.展开更多

The route is abundant with natural and human resources. In the research, quantitative and qualitative methods were integrated and scientific evaluation and analysis were made on tourism resources along the route according to National Standard of Classification, Investigation and Evaluation of Tourism Resources, with countermeasures proposed.展开更多

However, the economic development is at the cost of environment and resources, which will decrease the speed of economic development in return. China should gradually change the guideline from simply pursuing GDP growth to harmonious development, and establish a new set of performance-evaluating system, the resource-saving responsibility system as soon as possible.展开更多
