The Heber River Diversion Dam (Heber Dam) and 3.6 km penstock on Vancouver island, British Columbia, Canada was built in 1953 and by 2009, it had reached the end of its useful life due to the deteriorated wooden structures. A decision was taken to remove the dam, return the flows in the Heber River to pre-dam conditions and restore the footprint of the dam and penstock. Plans were developed for removal of the dam and contaminated materials including the creosote coated wooden penstock and other wooden structures associated with the dam and site restoration. Work on removal and restoration was undertaken over the summer and fall of 2012 and the spring of 2013. Restoration treatments were based on the use of natural processes as a model for recovery. The recovery of dam and penstock removal disturbances was initiated in the late summer and fall of 2012 with the fall dispersal of seeds from mature pioneering species that formed a significant part of the local undisturbed vegetation. This paper describes the treatments that were applied to enhance the natural recovery of the disturbed areas and the results of those treatments. The restoration treatments were designed to address the filters that were present in project areas. These were identified during an initial inspection in 2009 and were centred on compaction of substrates and a lack of micro-sites. In addition to the use of natural processes for the restoration of project disturbances, a local First Nations crew was hired to transplant sword ferns (Polystichum munitum (Kaulf.) C. Presl) from the adjacent forest areas onto project sites to provide a social benefit from the restoration work. 展开更多

OBJECTIVE: To supply literature for developing an international standard of auricular acupuncture points. METHODS: Electronic database searches were con- ducted in the Chinese National Knowledge Infra- structure and VlP, and the Western databases, Pubmed, the National Science and Technology Li- brary, and the German Journal of Acupuncture, from 1990 to April, 2012. We also searched the doc- uments of international symposiums for auricular acupuncture points (AAPs). Keywords were "auricu- lar points", "auricular acupuncture points", "ear points", or "auriculotherapy" RESULTS: Basic and clinical research on AAPs was performed in China, the United States, France, andGermany. Clinical AAP research was done in Italy, Austria, Switzerland, Spain, the UK, Holland, Japan, Russia, and Africa. However, AAP research was not communicated internationally. The World Federa- tion of Acupuncture-Moxibustion Societies recom- mended international standard of auricular acu- puncture points (ISAAPs). Standardized nomencla- ture and locations of AAPs would provide a solid basis to draft an international standard organiza- tion. CONCLUSION: Experts need to find common points from different countries or regions, provide evidence of different ideas, and list the proposal as a recommendation for an international standard. 展开更多
