The challenge for sustainability educational programs lies in how to imbue students with the strong motivation necessary to move the world in a more sustainable direction. Five universities in Japan have mutually collaborated in the design and development of a unique curriculum and education system for sustainability science since 2008. Specifically, they have developed a common and remote lecture system called the “Frontier of sustainability science” (FSS). This paper discusses the concepts and challenges of FSS and how it was organized to teach students to actively learn how to work with people of various disciplines to realize interdisciplinarity. 相似文献

Since establishment of the ISO 14001 environmental management system in 1996, Japanese facilities have led the world in numbers of certifications. This research utilises survey data from more than 1700 Japanese facilities as well as follow-up interviews to identify the determinants of ISO certification, to examine the differences between early, recent and in-process certifiers, and to understand how ISO 14001 certification affects various environmental and managerial outcomes in Japan. Findings show that ISO certified facilities are larger and report higher levels of environmental management capacity. In addition, early certifiers are more likely to have established voluntary environmental agreements and are more active in international trade and business. Findings also provide evidence that while many facilities believe that ISO 14001 certification is excessively costly, they also report that certification has resulted in the establishment of new energy efficiency and waste reduction targets and higher target levels. Nevertheless, evidence indicates that certification does not generally result in longer-term outcomes such as post-certification adjustment of non-regulated targets. 相似文献

Thermal remediation of contaminated soils and groundwater by injection of hot air and steam using large‐diameter auger in situ soil mixing effectively remediates volatile and semivolatile organic compounds. This technology removes large amounts of contamination during the early treatment stages, but extended treatment times are needed to achieve high removal percentages. Combining thermal treatment with another technology that can be injected and mixed into the soil, and that continues to operate after removal of the drilling equipment, improves removal efficiency, and reduces cost. Using field‐determined pseudo first‐order removal rates, the cost of the combined remediation of chlorinated volatile organic compounds (CVOCs) by thermal treatment followed by reductive dechlorination by iron powder has been estimated as 57 percent of the cost of thermal treatment alone. This analysis was applied to a case‐study remediation of 48,455 cubic yards, which confirmed the cost estimate of the combined approach and showed over 99.8 percent removal of trichloroethene and other chlorinated VOCs. © 2010 Wiley Periodicals, Inc. 相似文献

Biodegradation of the polychlorinated naphthalenes (PCNs) 1,4-dichloronaphthalene (1,4-DCN), 2,7-dichloronaphthalene (2,7-DCN), and 1,2,3,4-tetrachloronaphthalene (1,2,3,4-TCN), by the white-rot fungus Phlebia lindtneri was investigated. 1,4-DCN was metabolized to form six metabolites by the fungus. It was estimated from GC–MS fragment patterns that the metabolites were four putative hydroxylated and two dihydrodihydroxylated compounds. One of the hydroxylated products was identified as 2,4-dichloro-1-naphthol by GC–MS analysis using an authentic standard. This intermediate indicated chlorine migration in a biological system of P. lindtneri. 2,7-DCN was metabolized to five hydroxylated metabolites and a dihydrodihydroxylated metabolite. Significant inhibition of the degradation of DCNs and formation of their metabolic products was observed in incubation with the cytochrome P-450 monooxygenase inhibitor piperonyl butoxide. The formation of the dihydrodiol-like metabolites, chlorine migration and the experiment with P-450 inhibitor suggested that P. lindtneri provides hydroxyl metabolites via benzene oxide intermediates of DCNs by a cytochrome P450 monooxygenase. In addition, P. lindtneri degraded 1,2,3,4-TCN; two hydroxylated compounds and a dihydrodihydroxylated compound were formed. 相似文献

Summary. The major component of the trail pheromone of
the myrmicine ant Crematogaster castanea
has been identified as (R)-2-dodecanol from
the tibial glands of the hind legs. The substance gave activity comparable to the
contents of 8 tibial glands at a concentration of 1 pg per 32 cm trail. 相似文献

Oxidative stress generating active oxygen species has been proved to be one of the underlying agents causing tissue injury after the exposure of Eucalyptus (Eucalyptus spp.) plants to a wide variety of stress conditions. The objective of this study was to perform data mining to identify favorable genes and alleles associated with the enzyme systems superoxide dismutase, catalase, peroxidases, and glutathione S-transferase that are related to tolerance for environmental stresses and damage caused by pests, diseases, herbicides, and by weeds themselves. This was undertaken by using the eucalyptus expressed-sequence database (https//forests.esalq.usp.br). The alignment results between amino acid and nucleotide sequences indicated that the studied enzymes were adequately represented in the ESTs database of the FORESTs project. 相似文献

Purification and immunolocalization of a vitellin-like protein from the Pacific oyster Crassostrea gigas 总被引:4,自引:0,他引:4
A female-specific protein from the hemolymph, and a related ovarian protein were identified in the Pacific oyster Crassostrea gigas using immunological procedures. The latter protein was isolated from ovarian extract by a combination of precipitation in distilled water, ammonium sulfate fractionation, hydroxylapatite chromatography and gel filtration on a Sepharose 6B column, and was identified as a macromolecular glycolipoprotein of 500 kD; sodium dodecylsulfate polyacrylamide gel electrophoresis, under reducing conditions, revealed seven heterogeneous polypeptides. Using a specific antiserum against purified protein, we also examined the immunohistochemical distribution of the protein at light- and electron-microscopic levels. Light microscopy revealed its presence in the oocytes, and electron microscopy identified it in yolk granules and the vitelline coat of the oocytes. These results indicate that the purified protein is a vitellin-like protein. Since no organ other than the ovary reacted with the antiserum, it is probable that the protein is produced inside the ovary, probably autosynthetically by oocytes. 相似文献
