Customers, the public generally, the water industry, its regulators and the government are aware that water can be a scarce and costly product. Resource planning and development must increasingly be viewed as a combined package of water efficiency in (a) use, (b) metering and tariff policy, (c) leakage reduction, and (d) physical schemes.
Droughts, fears over possible climate change, concerns about resources and the environment, a greater awareness of the role and costs of the water industry and statements by the Department of the Environment, the Office of Water Services, and the National Rivers Authority have added weight to this sensible shift in emphasis.
However, society needs reliable water supplies and cannot completely rely upon the uncertain impact that demand side-measures may bring about – nor, even where achieved and cost-effective, on the important savings in losses. New resource schemes can take many years to implement. Therefore, in order to ensure adequate and reliable supplies, plans for new schemes must be brought to a state of readiness, and, in many cases, implemented. 相似文献

With rapid urbanization in China, an increasing building density has squeezed the urban public space. Community streets are occupied by motor vehicles or other functions, and can no longer sufficiently support children to carry out safe and independent activities. As an important space for children’s daily natural contact and social activities, the lack of the spatial function of streets results in a decline in children’s subjective initiative and social abilities. The United Nations has stressed the importance of community as the basic unit of space for children’s daily activities in building child friendly cities. It is urgent to reshape child-friendly community streets and support children’s healthy growth. Integrating previous research results on affordance theory and design, children’s growth and environment, and street-game spaces, this study focuses on investigating 23 community streets in four residential communities in Nanjing through questionnaires, interviews, observations, and other methods. Then, from the perspective of cognitive affordance, functional affordance, and social affordance, it analyzes the behavioral possibilities provided by the environment and the needs of the children-user group. Finally, from the perspectives of openness and security, preference and diversity, positive and negative, and reality and potential, it proposes a method to assess the existing environment. This study aims to extract the significant characteristics of the built environment that effectively support and promote children’s outdoors activities, and explore the design strategy of improving street space sharing through optimizing space elements and structure at the medium and micro levels, so as to respond to multiple goals including livable city development from the perspective of child friendliness. This study also tries to change the logical way of design thinking and provide an eco-psychological perspective on how to build a child-friendly community. 相似文献

研究针对徽州传统民居的庭院空间展开空间组织模式分析,对63处传统民居庭院进行调研,提取了面积、面积比、长宽比、饱和度和边界系数五个量化指标对庭院空间进行描述,并运用聚类分析的方法对庭院空间进行分类。总结出中小规模方整型、中小规模条型、中小规模不规则型和大规模复杂型四种庭院类型,在此基础上对庭院位置与其中要素的分布规律进行归纳。研究得出:四类庭院在位置分布与要素布置上均有所不同,中小规模方整型庭院作为空间过渡与补充,以前院和后院居多,多布置绿化、漏窗等要素;中小规模条型庭院以前院为主,组织规模较大的宅居组团的入口交通,要素上多以构筑物、拱门、字匾和二次轮廓要素结合布置;中小规模不规则型庭院往往作为宅居空间中的亮点,多位于前院和侧院,以绿化、水面、漏窗要素居多;大规模复杂型庭院多为生活化的后院,绿化、水面、石凳等要素较多。 相似文献

大跨度钢结构的滑移是一个动态过程,滑移推力、环境荷载、轨道承载力、轨道平顺性等因素对结构准确就位均有影响。为此,提出了一种能够监测滑移施工过程结构安全、稳定及滑移同步性的方法,该方法通过模拟分析施工滑移过程,准确预判滑移中结构出现损伤的位置和程度,提前采取措施;通过实时在线监测结构滑移施工过程中多项参数的变化,避免滑移过程中结构的应力集中、局部变形过大、脱轨、失稳及倾覆。以大同美术馆钢结构屋盖滑移施工监测为例,在滑移前对滑移施工过程进行模拟分析和监测系统安装,对滑移阶段结构关键构件的应变、位移、构件变形及环境温度进行实时监测、分析与反馈。结果表明:大跨度钢结构滑移受温度、轨道平顺性、轨道处结构变形值、顶推设备误差影响;采用有限元模拟分析、现场监测、实时分析与反馈的监测方法,可有效控制滑移过程中结构的内力、变形、各轨道滑移的同步性及结构的整体稳定性。 相似文献

Pollution of water by sewage and run-off from farms produces a serious public health problem in many countries. Viruses, along with bacteria and protozoa in the intestine or in urine are shed and transported through the sewer system. Even in highly industrialized countries, pathogens, including viruses, are prevalent throughout the environment. Molecular methods are used to monitor viral, bacterial, and protozoan pathogens, and to track pathogen- and source-specific markers in the environment. Molecular techniques, specifically polymerase chain reaction-based methods, provide sensitive, rapid, and quantitative analytical tools with which to study such pathogens, including new or emerging strains. These techniques are used to evaluate the microbiological quality of food and water, and to assess the efficiency of virus removal in drinking and wastewater treatment plants. The range of methods available for the application of molecular techniques has increased, and the costs involved have fallen. These developments have allowed the potential standardization and automation of certain techniques. In some cases they facilitate the identification, genotyping, enumeration, viability assessment, and source-tracking of human and animal contamination. Additionally, recent improvements in detection technologies have allowed the simultaneous detection of multiple targets in a single assay. However, the molecular techniques available today and those under development require further refinement in order to be standardized and applicable to a diversity of matrices. Water disinfection treatments may have an effect on the viability of pathogens and the numbers obtained by molecular techniques may overestimate the quantification of infectious microorganisms. The pros and cons of molecular techniques for the detection and quantification of pathogens in water are discussed. 相似文献
