Significant developments in sustainable development law and governance: A proposal

This article develops a practical proposal for progress on sustainable development law. It examines the prospects for an international sustainable development law to provide a framework for more effective, coherent governance. Sustainable development law is briefly defined and an analytical framework is provided. Different degrees of integration between economic, social and environmental law are described. Certain principles of international law related to sustainable development are also highlighted. It is argued that these principles may serve to guide law‐makers and jurists where social, economic and environmental law and policy conflict or overlap. Continuing, underlying questions of sustainable development governance are addressed and its global frameworks analysed. The article also focuses on the 2002 World Summit on Sustainable Development, held in Johannesburg in August‐September 2002, and its specific mandate for the United Nations Commission on Sustainable Development (UNCSD) to take related legal developments into account. The article advances a proposal: that governments, economic, social and environmental intergovernmental organizations and other actors establish a ‘network of inquiry’ with members from relevant groups, including legal and academic organizations, and other expert groups, in order to follow, research, analyse and debate legal developments in a balanced way.     

Stabilization and utilization of hospital waste as road and asphalt aggregate

This article reports the operational results of the effective utilization of hospital waste molten slag produced using a high-temperature melting system, and being operated at a hospital in Selangor, Malaysia. The hospital waste is incinerated and subsequently melted at 1200°C. Scanning election microscope (SEM)/EDX results showed that the slag produced after melting contained amounts of SiO₂, CaO, and Al₂O₃ in excess of 53%, 9%, and 16%, respectively. The results from a leaching analysis on the slag produced proved that the melting process had successfully stabilized the heavy metals. The use of this slag as an alternative material to replace conventional aggregates for road construction was studied. The results from aggregate and asphalt mix tests showed that the slag produced fulfills all the requirements of an alternative aggregate. The average asphalt content, or the optimum asphalt content to be mixed with hospital waste molten slag, was found to be about 5.53%.     

稳定同位素混合模型揭示的长江下游新石器时代人群摄食策略

长江下游地区是稻作农业的主要起源地之一。然而,水稻对长江下游新石器时代人群饮食的贡献程度仍不清晰。稳定同位素混合模型能够量化揭示长江下游地区史前人群的摄食策略。系统收集长江下游地区已发表的人骨、动物骨和植物稳定碳氮同位素数据,基于稳定同位素混合模型,对长江下游地区新石器时代人群的摄食策略进行研究。结果发现：距今7.0—5.3 ka长江下游地区人群可能摄食多种动植物资源,该时期水稻对人类饮食的贡献与其他植物资源基本相当。距今5.3—4.3 ka,水稻已超过其他动植物资源,成为美人地遗址人群的主要食物资源。研究揭示了长江下游新石器时代文明化进程与稻作农业发展具有同步性,狩猎采集经济则为该区域文明化进程起到基础支撑作用。     

高浓度废液纳滤膜分离工艺设计

当进行高浓度废液纳滤膜分离工艺设计时,必须首先进行纳滤膜分离工艺试验,通过工艺试验确定：纳滤膜型号,完成膜的筛选工作;确定纳滤膜分离规律、分离模型、膜污染规律。利用获得的数学关系式确定主要操作运行压力、浓缩液流量、膜面积、组件数目、膜组件排列方式、冷却循环系统设计、纳滤膜污染的预测与清洗系统设计。纳滤膜清洗系统与自控系统应该根据试验结果并考虑纳滤膜生产商提供的数据进行设计。
