As part of the Virgo Cluster Survey Tracing Ionised Gas Emission, a blind narrow-band H ? +[NII] imaging survey cluster carried out with MegaCam at CFHT, we discovered eight massive (10 10 ? M star 11 ? ) lenticular galaxies prominent ionised gas emission features in their inner (a few kiloparsec) regions. These are either filaments similar to those observed cooling flows (two galaxies), or the...

The emission of biogenic volatile organic compounds, hereafter referred to as BVOC, is well accepted as a dominant factor in atmospheric chemistry and physics. Despite this wide acceptance we still face significant gaps in our knowledge of emission budgets and emission regulation. We need more data on emission qualities and quantities which can only be gained by experimental work providing supp...

In this study, we examine various effects of carbon emission regulation enacted in South Korea. We provide empirical evidence regulated firms strategically hedging against potential risks by increasing the number directors with environment-related backgrounds. also find that relationship is clearly evidenced when firm owned a lower proportion foreign investors. Further analysis shows these succ...

In models of plant volatile isoprenoid emissions, the instantaneous compound emission rate typically scales with the plant’s emission potential under specified environmental conditions, also called as the emission factor, ES. In the most widely employed plant isoprenoid emission models, the algorithms developed by Guenther and colleagues (1991, 1993), instantaneous variation of the steady-state...

Chengdu, China, is experiencing rapid economic growth and urbanization at a cost of serious air pollution problems. China has developed a series of policies to reduce PM2.5 emissions and to reform energy structure. However, problems exist which may prevent effectively implementation of the PM2.5 policies, include poor PM2.5 monitoring, isolated environmental management, lack of health improveme...

Congestion pricing strategy has been recognized as an effective countermeasure in the practical field of urban traffic congestion mitigation. Despite the positive effects of congestion pricing, its implementation has faced problems. This paper investigates the issue of environmental equity in cordon pricing and a park-and-ride scheme. Although pollution decreases inside the cordon by implementa...
