The application of direct-flame incineration to successfully eliminate a smoke-oil-mist and odor problem in the manufacture of rubber-base rug underlay, is presented. The investigation of various air pollution control processes leading to the development and adoption of the direct-flame incineration system, is covered. The rug-underlay curing process incorporating the direct-flame incineration system with primary heat recovery is described. Results and discussion of a source test to determine the effectiveness of direct-flame incineration in this application are included. 相似文献

A conference was held on October 30-31,1990 to examine discrepancies between the output of vehicle emission factor models (MOBILE and EMFAC), field and laboratory measurements of vehicle emissions, and observed ratios of pollutants in urban atmospheres dominated by vehicle emissions. There was a general consensus that significant discrepancies exist and that these discrepancies must be resolved. A number of research recommendations were made as to how models and model inputs could be improved, and what additional laboratory and field work should be conducted. 相似文献

We investigate the phylogeography of California (Zalophus californianus) and Galápagos (Z. wollebaeki) sea lions and describe within-population structure for the California sea lion based on mitochondrial DNA. Fifty control-region
haplotypes were found, 41 from Z. californianus and 9 from Z. wollebaeki, with three fixed differences between the two species. Ranked population boundaries along the range of Z. californianus were defined based on the Monmonier Maximum Difference Algorithm, resulting in five genetically distinct populations, two
in the Pacific Ocean and three inside the Gulf of California. A Minimum Spanning Network showed a strong phylogeographic signal
with two well-defined clusters, Z. californianus and Z. wollebaeki, separated by six base-pair differences, supporting the existence of two genetically distinct species with an estimated divergence
time of ~0.8 Ma. Results are discussed in the context of the historical geologic and paleoceanographic events of the last
1 Ma in the eastern Pacific. 相似文献

The latest evidence relating to the enterprise zone experiment in Britain is provided in a recent report published by the Department of the Environment. The note analyses this evidence to provide an indication of the scale of economic activity taking place within the zones. The note suggests that the simplified planning regime of the enterprise zones actually plays a relatively minor role in facilitating economic change and concludes that more detailed evidence is required in order to achieve a full understanding of the effects of enterprise zones. 相似文献

Community participation is becoming increasingly popular within the field of disaster management. International disaster policies, frameworks and charters embrace the notion that communities should play an active role in initiatives to identify vulnerabilities and risks and to mitigate those dangers, and, in the event of a disaster, that they should play a proactive part in response and recovery (see, for example, UNISDR, 1994; The Sphere Project, 2004; United Nations, 2005). A number of studies have investigated the participation of communities in disaster preparedness and mitigation efforts (see, for instance, Scott‐Villiers, 2000; Andharia, 2002; Godschalk, Brody and Burby, 2003), There is, however, limited reflection on the challenges to ensuring participation in the operational context of disaster response. This paper draws on a study of the policy and practice of participatory damage assessment in Fiji to identify and discuss the barriers to formal implementation of community participation in a post‐disaster context. 相似文献
