Abstract: Equations to calculate the hydraulic residence time (HRT) of complete‐mix reactors (CSTR), with or without recirculation, under unsteady‐state condition are developed in this study. Recirculation does not affect the hydraulic ...

Abstract: Volatilization of selected organic compounds from water without agitation has been studied. Mathematical models, incorporating Fick's diffusion law, are developed for volatilization under quiescent condition. A theoretical ...

Abstract: The balance between overall economic growth and protection of the environment is an important research topic of urban sustainable development. In 2005, Shenzhen promulgated the regulations, Administrative Regulations of ...

Abstract: Public resources such as transportation, hospitals, parks, and schools are important factors in housing prices. However, studies on property value have mainly concentrated on transportation, and few studies have focused ...

Abstract: To explore the effects of some operating conditions on NO removal efficiency in a packed tower, the denitration process was simulated in a laboratory-scale packed tower using an ammonia solution containing Fe(II) ethylene ...

Abstract: Long-span, single-layer spatial grid structures are widely used in public buildings. The progressive collapse of such structures could cause great losses of property and human life. To accurately capture the performance ...

Abstract: As an effective approach to sustainable urban planning, integrated urban land-use zoning can contribute to fully understanding the integrated characteristics of urban land-use system, indicating the trend and possibility ...

Abstract: A dynamic experiment of progressive collapse constitutes the basis of a collapse-resistant analysis. To achieve broad applicability and avoid superfluous influencing factors, two representative substructures extracted from ...
